QC #: 329 - Status: Closed

QC #: Project Date Reported: Area: 329 Delphi 11/11/1996 RTL\Delphi\WinAPI Description Steps:MakeLCID and MakeLangId functions should be added, as in the Win32 macros. All the other associated macros (primary from LANGID, etc.) should be added as well.


QC #: Project Date Reported: Area: 584 Delphi 4/9/2002 IDE\Structure Pane Description Steps:[QC Short Description] Strcuture View (formerly Object TreeView) doesn't automatically scroll when in Drag&Drop [QC Description] When designing complex forms the content of Structure View doesn't fit on the screen. If you then try to move components in the Structure TreeView by Drag&Drop you can't drop it onto a TreeView node which is currently not visible because the TreeView doesn't scroll when you're pointing your mouse near the edges of the TreeView. That way Object TreeView loses it's most important feature (IMO) ! QC Entry 584

1. Create a new application 2. Drop quite a few buttons etc. on the form and a PageControl. 3. Open the Object TreeView (Alt+Shift+F11) 4. Resize the Object TreeView window so that not all nodes are visible and the scrollbars appear 5. Now try to drag one of the buttons TreeNodes to the edges of the TreeView exp: TreeView should automatically scroll act: Nothing


QC #: Project Date Reported: Area: 1124 C++Builder 9/9/2002 IDE\Translation Tools Description Steps:I can't port existing BCB5 translated applications. AFAICT there are several faults in the resulting BPRs including: UNITNAME is always "Form" CONTAINERID is always empty (though this may be correct). In addition "#pragma resource" has been changed so that you need double '\\'s to represent a single '\'. Having fixed these issues I can get the project to Build and Make but I get EResourceNotFound on running and when I try to open the form for viewing/designing I just get taken to the DFM in the edit window. ---------

1.Choose a VCL project with several forms. 2.\File\New\ and select Resource DLL Wizard 3.Click to the language selection page and enable a foreign language.4.Click on to finish and allow the IDE to recompile and create the new project. You will find the new project has only one form (probably the first listed in your original project) and that double clicking the form in the Project Manager only opens the file in the text editor. The pop-up menu has 'View as form' greyed out. If you attempt to compile this project it will fail at a #pragma directive. If you fix this by replacing '\' with '\\' it will compile and link but the

I tried recreating the project from scratch but after running the Resource DLL Wizard the translation project only had the first form listed. Aside from that it appeared to have the same BPR defects as the upgraded BPR. -------- None of the ITE menu items appear in the IDE although it is listed as an available package.

resulting DLL fails when you try and run it and is obviously deficient. // ADDITIONAL EXAMPLE OF 'BROKEN ITE' ////////////////////////////////// The 'RichEdit' example project shows some aspects of how broken the ITE is. Each international project does at least have two forms but: 1.They're both called "Form" in the Project Manager 2.You can't view/edit them as forms..only as DFMs. FWIW if you build the project it does work but obviously in its current state it would be a PITA to maintain.

QC #: Project Date Reported: Area:1346 Delphi 5/24/2002 IDE\Project Management\Project Manager

Description Steps:[QC Short Description] control build order via drag and drop instead of endless "Build sooner/later" [QC Description] Like many others my projects (in the realworld sense) consist of quite a big number of individual projects (in the Delphi sense). Of course I need to order these based on their inter-dependencies to ensure a "build/compile all projects" will succeed. When I add projects to the project group they're always added at the bottom and I have to go through an almost endless cycle of right click/build sooner steps to put the new project in the place it belongs.It would be much nicer if I could just drag it to the desired position. An intermediate solution would maybe be if the new project would at least be inserted at the position where I invoked the "Add new/existing project" from the context menu. I suggest both.

QC #: Project Date Reported: Area: 1936 Delphi 7/26/2002 IDE\Search\Find in Files Description Steps:[QC Short Description] Allow "find in files" in properties on forms/datamodels/frames (DFMs) [QC Description] When finding in files only the source code is searched. There is no such function for searching in all forms / data models within a project / directory etc. Example: Your customer asks you to change all texts / labels / ... from Automobile to Vehicle. You know this word is present is source code, on many forms in captions, hints etc.

Do a "Find in files" on Automobile with the (Associated files checkbox enabled or something like that). When you select the Automobiles found on DFMs it popups the form, selects the correct component/control, popups the Object Inspector and selects the correct property. QC Entry 1936

QC #: Project Date Reported: Area: 2480 C++Builder 9/24/2002 RTL\C++\Miscellaneous Description Steps:[QC Short Description] strtol and strtoul ( _i64toa and _ui64toa ? ) malfunction [QC Description] Short description: strtol and strtoul ( possibly _i64toa and _ui64toa as well) fail to detect input number overflow in some cases and return wrong result. Tested with BC 5.02, BCB5, BCB6( thanks to Jose Hortal) --------------------------------------------------------- Long description: When parsing input string with strto(u)l, numbers "near to" but greater than ULONG_MAX, both functions fail to detect overflow (don't set errno) and return wrong value. The numbers affected are defined with following rule: having char* ep; strtol( snumber, &ep , radix) where 'radix' defines valid _digits_ ['0','1',...N], AND if the last (rightmost) digit of ULONG_MAX converted to 'radix' representation is *not* equal to last valid digit N defined by 'radix', THAN all values between ULONG_MAX+1 and ULONG_MAX+n will be

1. bcc32 foo.cpp 2. foo.exe 3. press <space> to continue (increment base) <escape> to exit //exp : no RTL bugs to be reported //res : only tests with base 2,4,8,16 or 32 pass Create console application with attached test code. On output, "RTL bug:..." message is displayed for every value that is parsed wrongly.

parsed wrong, where 'n' is the difference between last valid digit N defined by 'radix',and last (rightmost) digit of ULONG_MAX represented with base 'radix'. The result of both functions, strtol and strtoul, will be equal to n-1 in this case and errno value will not be set to ERANGE as expected. Gee, even I don't understand what I wrote above :-) I hope an example will help having char* ep; strtol( snumber, &ep , 10) where 'radix' defines valid _digits_ ['0','1',...,'9'], AND ULONG_MAX is represented as "4294967295" in 10 base. Last (rightmost) digit of that number is '5' and last valid digit for 10 base is '9' therefore they arenot equal. THAN n = 9 - 5 == 4 => all these values will be parsed wrong: 4294967295 + 1 = 4294967296 ( strtol = 0 / errno = 0) 4294967295 + 2 = 4294967297 ( strtol = 1 / errno = 0) 4294967295 + 3 = 4294967298 ( strtol = 2 / errno = 0) 4294967295 + 4 = 4294967299 ( strtol = 3 / errno = 0) See attached test program that will run through all valid bases and display values that are parsed wrong. --------------------------------------------------------- Details: Looking at RTL source in "\Source\RTL\source\io\scantol.c" around line 178 overflow condition is tested with: oldresult = result; result = result * radix + digit; if ((result - digit) / radix != oldresult) { status = 2; / * overflow * / result = sign ? LONG_MIN : LONG_MAX; break; } This test is buggy. At a first glance it looks like the same problem is in "Source\RTL\source\io\scn2i64.c" (not tested) which affects _i64toa and _ui64toa.

QC #: Project Date Reported: Area: 2499 Delphi 9/25/2002 IDE\Search\Find in Files Description Steps:[QC Short Description] Redo a search using F5 or ctrl-R [QC Description] If focusing on a search tab in the message view, it would be very neat if it was possible to repeat the search with a single keystroke. F5 (common for refresh) or Ctrl-R would be fine. QC Entry 2499

Note, you can now use a menu item, but there should be a keystroke for that


QC #: Project Date Reported: Area:2750 Delphi 10/28/2002 VCL\System Controls\TDdeServerItem

It is using try..finally for the clipboard.close but the functionality fails miserably for it lacks any clipboard.open statement. QC Entry 2750 [In Delphi 7]

1. Place a TDdeServerConv and a TDdeServerItem and fill the properties. 2. Call DdeServerItem.CopyToClipboard. 3. Go to Word and attempt to Paste this link, you will fail.

This code works as expected with D5. It does not work with D7, since RegisterClassAlias calls RegisterClass which is no longer comparing the class pointer before checking the class name, thus raising an exception on the second call.

After discussions on the newsgroups it appears that the error message is actually plain wrong and the code should compile cleanly. There is a workaround for this problem. QC Entry 2925

QC #: Project Date Reported: Area: 3399 Delphi 1/22/2003 Debugger\Breakpoints Description Steps:[QC Short Description] Add ability for breakpoint to be active only in selected thread [QC Description] I have to debug the same code that is run in a few different threads, those threads don't bother each other. When I put a break point in the code, debugger stops when each thread reachs this point, but I only want one particular thread to stop there, that's why I have to observe thread window if I'm in the right one. The nice solution would be to select thread in the Threads Window then query popup menu on a thread and select for example 'disable debug' if the debugger for a thread is active or 'enable debug' if the debugger for a thread is inactive. Thread state during debugging would be presented with appropriate icon. QC Entry 3399


QC #: Project Date Reported: Area: 3755 C++Builder 3/5/2003 Compiler\C++ Description Steps:// reopened for QC 3755 Compilier and Linker should make the following items accessable by script - perhaps included with the version information.

Integration Build Number (not product version) SKU (if relevant) these two data points, along with the platform (which can be determined by the test tool), and the name of the binary file, should exactly identify the binary under test. This allows for automatic, unambiguous logging of exactly what is being tested, and to prevent the testing of one version and attributing the results to another.


QC #: Project Date Reported: Area:3791 Delphi 3/13/2003 VCL\Win 32 Controls\TToolBar

Description Steps:[QC Short Description] Setting the Visible property of TToolButtons to False at runtime causes other TToolButtons to behave incorretly [QC Description] I have a TToolBar with aprox 10 buttons. At runtime I hide some of these buttons. Some of the buttons that are left behave incorrectly. One on the buttons now does nothing, and another calls the wrong button click event. However, shortcuts for the buttons and Button.Click both still work. If I maximize the form the buttons start to work again. I did find this piece of code which does work, but I do not want to do this everytime I show/hide buttons on a TToolBar. pCaption := TToolBar.Buttons[0].Caption; TToolBar.Buttons[0].Caption := ''; TToolBar.Buttons[0].Caption := pCaption; QC Entry 3791

Run the attached example. Click the referrals button to open the child form with the toolbar on. Now click the "Elective Exward" button and nothing happens except you get a mouse drag icon. Note using the ALT+W key still works. Now click the "Add" button and the "Elective Exward" button event is called but using ALT+A still works. All the other buttons work fine. Now resize the form and ALL the buttons begin to work correctly????


QC #: Project Date Reported: Area: 3820 Delphi 3/16/2003 RTL\Delphi\Date - Time Description Steps:This has also been reported for BCB/6.0, report #3526. I just copied the same report here. HoursBetween does not return the correct value of HoursBetween in some cases. By analysing the behaviour of the functions involved in returning the number of hours, i found that the problem seems to be localised on the Trunc function (called in HoursBetween) returning 999 as the truncated value of 1000.000008, calculated by the Hourspan function.QC Entry 3820 [Top Ten]

Compile and run the attached program. See the following output. FAIL #2 FAIL FAIL #2 indicates that the expected value of 1000 was not seen from HoursBetween. program Test; {$APPTYPE CONSOLE} uses SysUtils, DateUtils; var datebeg, dateEnd: TDateTime; RetVal: Integer;

Description Steps:[QC Short Description] StayOnTop Bug in Delphi 6 and 7 but not in Delphi5

The following is very simple test. 1.First create a new project in Delphi7, set some properties of the main form (Form1) like this : Left

[QC Description] There is a bug in Delphi 6 and 7, and BDS2006 (not in Delphi 5). A form with FormStyle=fsStayOnTop will not stay on topmost in some situations.The following is very simple test. 1.First create a new project in Delphi7, set some properties of the mainform (Form1) like this : Left = 388 Top = 165 Width = 264 Height = 132 Hint = '11111111111111111111111111111111111111111111111' FormStyle = fsStayOnTop Position = poDesktopCenter ShowHint = True 2.Then run this program, and start another program, for example, the notepad.exe . 3.Drag form1 of project1 to overlap the window of notepad. Now form1 is properly staying on topmost. 4.Active project1 and move mouse over form1, now you can see the long hint '1111111111111111111111111'. 5.When hint showing( This is important!), move mouse quickly and click the window of notepad. Do you see the window of notepad overlap form1?Just try some times to switch between program quickly, you can find that form1 is not staying on topmost. 6. If you compile this project under delphi5, this bug is gone. Why the bug occurred in Delphi7 ? I found that the VCL of Delphi7 changed Forms.pas. The implements in TApplication.RestoreTopMosts and TApplication.DoNormalizeTopMosts are differ from Delphi5 implements. Delphi5 implements: procedure TApplication.RestoreTopMosts; var I: Integer; begin if (Application.Handle <> 0) and (FTopMostLevel > 0) then begin Dec(FTopMostLevel); if FTopMostLevel = 0 then begin for I := FTopMostList.Count - 1 downto 0 do SetWindowPos(HWND(FTopMostList[I]), HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE or SWP_NOSIZE or SWP_NOACTIVATE); FTopMostList.Clear; end; end; end; Delphi7 implements: procedure TApplication.RestoreTopMosts; var I: Integer; begin if (Application.Handle <> 0) and (FTopMostLevel > 0) then begin Dec(FTopMostLevel);

= 388 Top = 165 Width = 264 Height = 132 Hint = '11111111111111111111111111111111111111111111111' FormStyle = fsStayOnTop Position = poDesktopCenter ShowHint = True 2.Then run this program, and start another program, for example, the notepad.exe . 3.Drag form1 of project1 to overlap the window of notepad. Now form1 is properly staying on topmost. 4.Active project1 and move mouse over form1, now you can see the long hint '1111111111111111111111111'. 5.When hint showing( This is important!), move mouse quickly and click the window of notepad. Do you see the window of notepad overlap form1? Just try some times to switch between program quickly, you can find that form1 is not staying on topmost. 6. If you compile this project under delphi5, this bug is gone.

if FTopMostLevel = 0 then begin for I := FTopMostList.Count - 1 downto 0 do SetWindowPos(HWND(FTopMostList[I]), HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE or SWP_NOSIZE or SWP_NOACTIVATE or SWP_NOOWNERZORDER); FTopMostList.Clear; end; end; end; Note the flags in SetWindowPos is important! Delphi7 has a extra flagSWP_NOOWNERZORDER. This flag make the main form not stay on topmost. When this hint window is showing, switching between programs trigerTApplication.RestoreTopMosts and TApplication.DoNormalizeTopMosts. The hint window is a topmost window too. These codes run and make form1 not stay on topmost. SYSOP (comment from Jordan Russell): > Forms with fsStayOnTop will only stay on top of other windows in the ** same ** application. > > Hence, I believe this report is wrong. No, that is only true of secondary forms. By design, fsStayOnTop main forms will stay on top of all applications. (Check TApplication.DoNormalizeTopMosts and you'll see that it makes an exception for the main form.) Please re-open. QC Entry 4162

QC #: Project Date Reported: Area: 5269 Delphi 7/17/2003 Debugger Description Steps:[QC Short Description] Add option to turn off "Source has been modified. Rebuild?" [QC Description] Add an Environment Option to turn on or off this message: "Source has been modified. Rebuild?" It is common to change code during debugging, whether intentionally or unintentionally. It is very annoying to be in the middle of debugging and have Delphi hang for 20 seconds while it determines if I have changed anything. It then interrupts what I am doing to ask me if I want to rebuild. I would like to turn this option off so that it never checks to see if I have changed anything. The compiler will check it again anyway the next time I build. (I'm using Delphi 6, so maybe this is already fixed in Delphi 7.) QC Entry 5269

Set a breakpoint in your code. Run the program to that breakpoint. Edit the code or add a comment, and save your work. Continue stepping through the code. Delphi will hang for a while, then ask if you want to rebuild.



Description Steps:Changing a Enumeration value that is published on a component causes undefined results. QC Entry 5338

Steps to produce 1. install the package attached with "TMyControl" 2. Open the Form1 from the Propread Project. 3. Make sure that the MyEnum property has the value enThree 4. save the form 5. remove the . from {.$DEFINE BUG} and recompile the package. 6. reopen the form. now the MyEnum property has the value enTwo, but no one has been noticed that the property was changed ! 7. do nothing else than save the form again. 8. Close the form and try to reopen the form. you will get the message "object expected on line 24" taking a look at the dfm you will see, that the MyEnum property has no longer a valid value assigned. The Problem is that GetEnumValue does return a (-1) if the Value does not exist. ReadPropValue from the reader does not check this value at all, and assigns it using SetOrdProp to the property. Delphi 5 raised a exception, which would be the correct solution.

QC #: Project Date Reported: Area: 5607 Delphi 8/12/2003 IDE\Code Editor Description Steps:[QC Short Description] Include a Source Code Formatter in Delphi's IDE [QC Description] I think it would be useful if Delphi could auto-format EXISTING code, not just new code as it's being typed. Perhaps include a Source Code Formatter, which does one or more of the following: - Properly indents all code in a file to a given number of spaces (Report 1131). - Arranges all Begin/End statements consistently according to a style.- Sorts implementation of procedures and functions (Report 424). - Correct all Upper/Lowercase variables according to VAR declarations (Report 972). - Has the ability to apply these style changes to a single file or all files in a project. I realize that there are 3rd party tools that do this, but it would be much

easier if Delphi included it. QC Entry 5607

Description Steps:TReader.ReadBoolean only performs a "ReadValue = vaTrue" check to determine its return value, and since ReadValue only blindly reads and casts a byte, ReadBoolean will always pass whatever type was written is the filer. This leading to ReadErrors being detected in further "correct" filer reads at best, and at worse, this can result in undetected data loss/corruption. Also present in Delphi 5 and 6. QC Entry 6585

QC #: Project Date Reported: Area: 7102 Delphi 1/28/2004 Midas\TClientDataSet Description Steps:TClientDataset slows down with large data volume. As the amount of data contained within a TClientDataset increases, the speed at which a constant amount of data is inserted deteriorates almost linearly. This creates an overhead that ranges from annoying for a small volume of data to unacceptable for larger volumes. Also appending only one more record to a TClientdataset containing many rows is very slow. The problem seems to be severely aggravated by the use of large VARCHAR fields QC Entry 7102

Description Steps:[QC Short Description] VarArrayRedim() mistakenly changes low bound of rightmost array dimension [QC Description] When VarArrayRedim is called on a multidimensional array (2 or more dimensions) it changes its rightmost dimension low bound to that of the leftmost dimension. For example, when a bidimensional array with dimensions [0..1], [2..5] is VarArrayRedim'd to 6 it will end-up having the dimensions [0..1], [0..6]. This is because the writer of VarArrayRedim() did not take into account the fact that the indices vector that is passed in the SafeArrayXXX() windows api functions contains indexes IN REVERSE ORDER. Therefore the assignment: with LVarArray^ do VarBound.LowBound := Bounds[DimCount - 1].LowBound; is wrong. It should be: with LVarArray^ do VarBound.LowBound := Bounds[0].LowBound; because Bounds[DimCount - 1] corresponds to the leftmost dimension, not the rightmost. This is mentioned in MSDN in the description for e.g. function SafeArrayGetElement(): rgIndices: Pointer to a vector of indexes for each dimension of the array. The right-most (least significant) dimension is rgIndices[0]. The left-most dimension is stored at rgIndices[psa->cDims - 1]. QC Entry 7524

Compile and run the attached application below. program BTS242389; {$APPTYPE CONSOLE} uses Variants, SysUtils; var V: Variant; begin V := VarArrayCreate([0,1, 2,5], varVariant); WriteLn(Format('[%d..%d] [%d..%d]', [VarArrayLowBound(V, 1), VarArrayHighBound(V, 1), VarArrayLowBound(V, 2), VarArrayHighBound(V, 2)])); VarArrayRedim(V, 6); WriteLn(Format('[%d..%d] [%d..%d]', [VarArrayLowBound(V, 1), VarArrayHighBound(V, 1), VarArrayLowBound(V, 2), VarArrayHighBound(V, 2)])); end. One would expect that the second message would display [0..1] [2..6] but it displays [0..1] [0..6] instead. Change the low bound of the first dimension to any number you want and run the program again. You will see that after VarArrayRedim the low bound of the second dimension will be the same as the low bound of the first dimension and not 2. NOTE: I added TVariantsTests.Test_VarArray_Redim to rtl\test\UnitTest.Variants.

QC #: Project Date Reported: Area: 8070 Delphi 5/5/2004 RTL\Delphi\Math Unit Description Steps:This also happens in BDS 2006 and Highlander. [QC Short Description]

With a TButton (Button1)and a TMemo (Memo1), code the following procedure TForm1.Button1Click(Sender: TObject); var e: extended; begin e := RoundTo(1.235, -2);

RoundTo and SimpleRoundTo are very sick [QC Description] Help says about RoundTo(): "Rounds a floating-point value to a specified digit or power of ten using Banker's rounding." And the D7 help further says gives these examples: RoundTo(1.235, -2) ->1.24 RoundTo(1.245, -2) -> 1.24 But in reality: RoundTo(1.235, -2) ->1.24 RoundTo(1.245, -2) -> 1.25 RoundTo does indeed "use" bankers rounding to arrive at its result, but it uses it incorrectly. For an example of good, well tested decimal rounding routines for the extended, double, and single number types, see my DecimalRounding (JH0) package in CodeCentral at URL: http://codecentral.borland.com/codecentral/ccweb.exe/listing?id=17998(I can give you my test program if you are interested.) The SimpleRoundTo function suffers a similar problem. The Help file says "SimpleRoundTo uses asymmetric arithmetic rounding to determine how to round values that are exactly midway between the two values that have the desired number of significant digits. This method always rounds to the larger value." SimpleRoundTo happens to give the correct results for the examples given in the Help file; but for other values, gives results that don't seem to "jive" with the Help description. E.g. SimpleRoundTo(1.005, -2) -> 1.00 Now, floating point experts will recognize that the possibility of an input decimal fraction number being "exactly midway between the two values that have the desired number of significant digits" is *very* small. This probably is so small, in fact, that the help definition of "midway" very rarely comes into play, as it did not in the example immediately above. The Help definition can however easily mislead the neophyte programmer. QC Entry 8070 [BCMF]

Memo1.Lines.Add(Format('RoundTo(1.235, -2) -> %0.4f (S.B. 1.24)',[e])); e := RoundTo(1.245, -2); Memo1.Lines.Add(Format('RoundTo(1.245, -2) -> %0.4f (S.B. 1.24)',[e])); end; When executed, you will get RoundTo(1.235, -2) -> 1.2400 (S.B. 1.24) RoundTo(1.245, -2) -> 1.2500 (S.B. 1.24) Notice the error in the second test.

QC #: Project Date Reported: Area:8800 Delphi 8/14/2004 Database\Data Aware Controls\TDBGrid

Description Steps:[QC Short Description] Mixing lookup fields with numeric and string keys in a DBGrid throws exceptions [QC Description] Added by Sysop <<<<<<<< This issue still exists in Delphi 2010. Please see attached Delphi project to reproduce this issue. >>>>>>>> When a DBGrid includes lookup fields with different types of keys (e.g.- String and numeric) then editing one field and then the other can throw exceptions for "key not found" and type mismatches. The problem seems to be in the DBGrid code on the first of two updates of the pulldown list where it incorrectly uses the previous key, from the previous field. If the type is different it causes problems. The second update corrects the problem. The exceptions are only seen in the debugger, not in the final application run by itself (i.e.- not seen by the user). This was only tried with ClientDataSets, though it is probably a problem with other data sources since it seems to be in the DBGrid code. QC Entry 8800

A simple BCB demonstration program is attached, or you can create your own: - Create a couple of lookup data sets, one with a numeric key and one with a string key. - Create a dataset that includes numeric and string fields to use as keys, and add two lookup fields, one based on the numeric key and lookup dataset and the other string based. - Drop a grid on your form and link it to the main dataset. - Add code to your form initialization to put some data in the lookup tables. - Run the application and make a selection from the pulldown list of the string based lookup field. Then try to make a selection from the numerically keyed lookup field pulldown. You will see the exception(s) in the debugger, and then be able to continue on and finally make the proper selection.

This is of course not an error but it can be rather anoying. I suggest a Ctrl/Shift/Alt F7/F8 or whatever key combination that will cause the debugger to not stop in other threads but only in the relevant thread.

QC #: Project Date Reported: Area: 22015 Delphi 12/7/2005 IDE\Code Editor Description Steps:[QC Short Description] Bookmark icon when font size is 8 [QC Description] When font in editor is Courier New and size is 8, when you use bookmarks in the editor, removing a bookmark will not remove the top line of the icon. It appears that the redraw routine follow the height of the font, and since the icon is a little bigger, the first pixel line of the icon will not be redrawn until you move the cursor up one line. QC Entry 22015

Open D2006 Go into Tools>Options>Editor Options>Display, set Editor font to Courier New and Size to 8 (or 9) and press Ok. Create a bookmark in source by using Ctrl+Shift+1. Press Ctrl+Shift+1 again and notice that a part of the icon will not be removed. Move the cursor up one line, and the icon part will disappear. Looks like the redraw of the icon use the font height, and the icon is higher than this height.



22088 C++Builder 12/8/2005 IDE\Packages Description Steps:[QC Short Description] Component does not appear in C++ tool palette [QC Description] If a Delphi package is installed without the option generating all C++ builder files, then it won't appear in C++ tool palette, which is correct. However, if you go back to the package and select "Generate all c++ builder files", rebuild and remove + reinstall package, the components still won't appear in C++ tool palette. It seems that it is marked as a Delphi package forever, until you recreate the package in Delphi and save it as a different name. QC Entry 22088

NOTE: I've tracked this down to the package cache in the registry. deleting this is a workaround. It should be deleted whenever a package is installed. Create a Package in Delphi, and create an empty TComponent descendent to go with it. Build and install. Create a VCL Form app in C++. Save and Close. Remove bpl from package list. Open Package again, go to Project Options | Linker | Generate all C++ builder files. Build and install. Open the C++ VCL Form app again. Try to find the component you've created in Delphi -- not found!


QC #: Project Date Reported: Area: 22809 Delphi 12/26/2005 IDE\Form Designer Description Steps:[QC Short Description] Access violation when deleting FlowPanel [QC Description] Under special circumstance (see steps), deleting a FlowPanel in the FormDesigner causes an AV which renders the IDE totally unstable, so it has to be killed with the Task Manager. QC Entry 22809 Stack: + $8[51F315B6]{rtl100.bpl } Classes.Classes.TList.IndexOf (Line 3018, "classes.pas" + 2) + $8 + $0[51F06B47]{rtl100.bpl } System.System.@HandleAnyException (Line 9980, "system.pas" + 13) + $0 + $41[7C903786]{ntdll.dll } RtlConvertUlongToLargeInteger + $41 + $9[7C90EAF5]{ntdll.dll } KiUserExceptionDispatcher + $9 + $6[5203C998]{vcl100.bpl } Controls.Controls.TWinControl.WndProc (Line 7242, "Controls.pas" + 101) + $6 + $C[52038674]{vcl100.bpl } Controls.Controls.TControl.Perform (Line 5018, "Controls.pas" + 5) + $C

// Note: SafeMM will make this reproduce consistently. 1. New VCL Form32 App 2. Put a FlowPanel on the form, resize it so it is big enough to hold 2 LabeledEdits. 3. Add two TLabeledEdit components to the panel; no need to set any properties 4. Select the FlowPanel, wait until the designer hint is shown 5. Press Del to delete the FlowPanel If the AV doesn't occur, press Ctrl+Z to undo the delete and repeat from step 4. I've personally never seen it AV on the first delete, but always on subsequent deletes. After the AV occured, you have to kill bds.exe, since the IDE can't close the form and therefore the project properly. If, after the AV, I put another component on the form (say a TButton), the Structure View gets updated and I can see that the FlowPanel and the LabeledEdits are still there, although not shown in the designer. The interesting thing is, that LabeledEdit2 is now parented by the form and not the FlowPanel!

QC #: Project Date Reported: Area:23373 C++Builder 1/11/2006 IDE\Code Editor\Code Folding

Description Steps:[QC Short Description] Editing/Entering code causes unfolding [QC Description] In a .cpp file, If I try to enter a new function wile the code is folded, typing the opening { for the new function causes all code following that point to unfold. I realize that the code is ill-formed at the moment I type the opening brace for a new function, but the editor sould let me perform normal functions without getting in my way. I see no reason to ever reevaluate folding dynamicly - anything that's folded or unfolded should stay that way until I invoke folding or unfolding again with a hotkey or menu choice. ADDED AFTER REPORT WAS CLOSED: This report was closed, I suspect due to the steps not being followed closely enough. Step 5 says to type an opening brace, not to type the brace followed by <Enter>. Just to be sure I have attached a simple demo project. I assume that the file will be folded if someone else opens it - if not, Fold Methods. When I add an opening brace { at the start of line 18 of FoldMain.cpp the three buttonClick methods unfold. Automatic block completion will stop this from happening if the { is followed immediately by the Enter key. QC Entry 23373

Updated Steps: - Create a new .c or .cpp file in the IDE - Enter this code // ----- #pragma region #pragma end_region 4| // ----- - Fold the region - Move the cursor to the pipe - type '2' Exp.: '2' is inserted Act.: '2' is inserted and the elided block is un-elided Also: same issue with #if...#endif blocks and #ifdef...#endif blocks. -- Original Steps: -- Open the attached project open FoldMain.cpp right click and Fold Methods type an opening { on line 18 //not all the methods following will unfold -------- File | New | VCL Forms Application - C++ Builder Add several functions to the .cpp file Right-click in editor and Fold | Methods

Add a new method near the top of the file (with several folded methods following it) Type the opening { for the new method (***and don't type anything else***) Code following the { will unfold

QC #: Project Date Reported: Area: 26801 Delphi 3/30/2006 Compiler\Delphi Description Steps:[QC Short Description] RTTI functionality for private and protected sections in classes [QC Description] Today, it's only possible to get RTTI information through a published section. Any published section is always public. This is also true for any components placed on any design surface (TForm, TDatamodule, TWebModule etc.). Because of the current RTTI all components must be placed inside a public section, violating the object creation rules. If RTTI is upgraded to also have possibilities to save variables etc. inside private and or at least protected section, we may eliminate this problem, and also create new possibilites for persistence. They would need some new sections for this, something like TYourClass = class private published protected published public published // today "published" The old "published" could be marked as deprecated, to preserve pattern, but it's not the most important issue. TypeInfo blocks could be adjusted to have visibility information. After the changes, TReader, TWriter needs to be updated with these new RTTI features.

A prime example is Chapter 13 of the C++ Developers Guide - "C++ language support for the VCL". The new Borland help information does not include this type of information. (Or if it does, I can't find it). Not understanding such detail can lead to subtle, hard-to-find bugs. In general, I beleive the online help is not a replacement to the "C++ Developers Guide" but rather a complement to it. As a minimum, an updated version of the PDF version of the "C++ Builder Development Guide" should be provided, and in the meantime provide the version 6 version for those not fortunate enough to have upgraded from a prior version.

The page ms-help://borland.bds4/bds4ref/html/NestedTypes.htm says, "Nested type declarations are terminated by the first occurance of a non-identifier token, for example, procedure, class, type, and all visibility scope specifiers." The word "occurance" should be "occurrence". The page ms-help://borland.bds4/bds4ref/html/StructuredTypes.htm says var Int1: array[1..10] of Integer; array[1..10] of Integer; ... Int1 := Int2; The second declaration should be Int2: array[1..10] of Integer; The page ms-help://borland.bds4/bds4ref/html/StructuredTypes.htm in the "Records (advanced)" section discusses constructors for records. However, it is not clear how to use these since records are not normally constructed. More explanation and an example would be good. The page ms-help://borland.bds4/bds4ref/html/DeclarationsAndStatements.htm in the "Iteration Over Containers Using For statements" section gives an example that has the statement "IDynArray := IArray1;". This won't compile. The compiler says, "Error: E2010 Incompatible types: 'TGenericIntArray' and 'Array'". The page ms-help://borland.bds4/bds4ref/html/DeclarationsAndStatements.htm#ForStmts has an example containing the lines TMyIntArray = array of Integer; ... Values := TMyIntArray.Create(100, 200, 300); However, the TMyIntArray.Create syntax doesn't seem to be documented. The page ms-help://borland.bds4/bds4ref/html/CallingProceduresAndFunctions.htm says, "No inlining will be done between units that are circularly dependent. This included indirect circular dependencies". The word "included" should be "includes".

QC #: Project Date Reported: Area: 34006 Delphi 9/15/2006 VCL\Action Classes Description Steps:[QC Short Description] TSearchFind action doesn't work with more than 64k bytes text [QC Description] If you add a standard action of Search category, the search function returns "Text not found" if it exists beyond the 64k boundary. Function SearchEdit in unit StdActns uses a variable called Size of type word to store the result of EditControl.GetTextLen. Although GetTextLen returns an Integer. The type of the Size variable should be changed to an integer. QC Entry 34006


QC #: Project Date Reported: Area: 34360 Delphi 9/22/2006 IDE\Dialogs Description Steps:[QC Short Description] Make the Tools | Options dialog sizeable [QC Description] I have noticed that many of the dialogs in BDS are now sizeable (compared to the same dialogs in BCB6). This is a great improvement. However, the Tools | Options dialog is still not sizeable, but it contains many controls that would greatly benefit from allowing the dialog to be sized.

Description Steps:[QC Short Description] Data loss in TDBGrid [QC Description] there is data loss if - record is edited using DBEdits and simultaneously shown in a DBGrid - user clicks on the empty are of a DBGrid

1. Download and run the attached test-case 2. Activate the second record by clicking on the cell showing "two" 3. Enter a different text (e.g. "test") into the DBEdit above the grid 4. click on the empty area in the grid below the records exp: updated value ("test") should show up in the grid act: value is cleared, i.e. data loss

See steps and attached test-case This is caused since in TCustomDBGrid.MouseDown there is a call to UpdateData instead of FDataLink.UpdateData (see workaround) QC Entry 34447


QC #: Project Date Reported: Area: 34774 Delphi 10/3/2006 Compiler\Delphi Description Steps:[QC Short Description] Documentation generation does not produce a valid xml file. [QC Description] The delphi win32 compiler can produce xml documentation if enabled under project options. This xml is sometimes invalid for specific pieces of pascal code. QC Entry 34774

create an empty win32 delphi project. enable xml documentation generation under project options. example: program BTS246097; {$APPTYPE CONSOLE} const a = '&'; b = '$'; c = [a, b]; begin end. Which produces an xml file containing: <const name="a" type="Char"> <value> $26 </value> </const> <const name="b" type="Char"> <value> $24 </value> </const> <const name="c" type="Set"> <value> ['&','$'] </value> </const> This is incorrect, the & should have been escaped to & Also: The generated documentation also does not include the 'low' and 'high' of the first dimension of a multidimensional array TAnArray = array[Char, Byte, 0..12] of TEnum; <array name="TAnArray"> <array name="TAnArray" low="0" high="255"> <array name="TAnArray" low="0" high="12"> <element type="TEnum" /> </array> </array>

</array> Also the manual basicly says nothing about what the comments should look like, we assume it should mimic the visualstudio style ? There seems to be a basic design issue with how type reference are handled btw: Usually an type attribute is added to whateer the type refers tp, but for some types, like pointers and arrays it is added as a childtag, but in some cases a type tag is used for unclear reasons. Also most of the time there is no reference to the namespace of a type, so you need to have global knowledge or a search engine to make links between interfaces. Also : type HRESULT = type Longint; does not yield anything in the xml documentation

Description Steps:[QC Short Description] Allow DllRegister, DllUnregister (and other affected routines) to call a user-defined procedure [QC Description] Allow DllRegister, DllUnregister (and other affected routines, probably DllGet) to call a user-defined procedure. On Windows 2000 and later, a user account can be a Limited User Account (LUA). In that case, if a Delphi-written in-proc server (written as an EXE, not a DLL) is called, it will attempt to register the OLE classes implemented in the EXE into the registry through HKCR, which is mapped into HKLM\Software\Classes. This will cause an AV when the application is executed in a LUA account. One of the ways to overcome this issue is to use the RegOverridePredefkey to redirect HKCR to HKCU\Software\Classes instead. This can be implemented by defining and calling a OnBefore and OnAfter variable (of procedure). See also Clarify 642168. QC Entry 34805

Compile and run the attached program below. See the following output instead of the expect output of PASS. FAIL lResult='This is a tes'

AnsiExtractQuotedStr will be shortened by one character. e.g. '"This is a test' will only return 'This is a tes' as the result instead of 'This is a test'. See Steps and attached test case QC Entry 35323

See how the last character of the string is dropped. program BTS242470; {$APPTYPE CONSOLE} uses SysUtils; var lResult: String; lStr: PChar; begin lStr := '"This is a test'; lResult := AnsiExtractQuotedStr(lStr, '"'); if lResult = 'This is a test' then WriteLn('PASS') else WriteLn('FAIL lResult=', lResult); end.

QC #: Project Date Reported: Area:37344 Delphi 6/20/2007 VCL\Win 32 Controls\TComboBoxEx

Description Steps:The destructor of TCustomComboBoxEx calls CoUninitialize. This should only be called if a preceding call to CoInitialize returned success. This is a problem if the application uses COINIT_MULTITHREADED as threading model. Calling CoInitialize with both COINIT_MULTITHREADED + COINIT_APARTMENTTHREADED doesn't make sense, because COINIT_MULTITHREADED = 0; constructor TCustomComboBoxEx.Create(AOwner: TComponent); begin //... if Assigned(CoInitializeExProc) then

Add the following code to a unit: initialization CoInitFlags := COINIT_MULTITHREADED; end. Then add TComboBoxEx to a dynamically created form.

This is an often needed feature and such a would prevent having to write more complex Windows API code like this: ActiveLineNo := Perform(EM_LINEFROMCHAR, -1, 0); when this would be easier to read: ActiveLineNo := RichEdit1.ActiveLineNo; The RichEdit1.CaretPos.Y property returns the line number but only for non wrapped lines.

QC #: Project Date Reported: Area: 38921 C++Builder 1/18/2007 IDE\Performance Description Steps:[QC Short Description] IDE Compiler searching & opening the same file multiple times during compiling [QC Description] This is Technically a duplicate of QC: 13775 but with everything together in a cohesive whole with the reasons why it occurs. Asked for by David Dean. When BDS 10/11 compiles a project the internal compiler re-searches for header (and source) files mulitple times down the entire include path; even though it should know where it found it last time -- this is waisting a lot of time duplicating efforts that it should already know about. All of Code Insight features also uses the internal compiler which then causes CI to be a lot slower than it can be. QC Entry 38921

Attached is Andreas Plugin with my mod to track the stats per compile 1. Load BDS 110 project, Install plugin 2. Run->Load Process 3. Choose BDS.exe and run 4. Open the WPM sample application located in ($BDS)\Demos\CPP\Apps\Wpm 5. Project -> Options 6. Disable ALL pre-compiled headers (otherwise your numbers are not correct) -> OK 7. Project -> Build WPM 8. Switch to BDS where you are debugging IDE and you should have on your eventlog: File In Known: 308, In Missed: 655, Total: 1174 Date In Cache: 140, Total: 279 8. Switch back to BDS, and click in the source 9. Hit CTRL-Space, to activate one of the Code Insight features. File In Known: 86, In Missed: 294, Total: 591 Date In Cache: 139, Total: 139 Now these numbers grow exponentionally (yes, exponentionally) each additional unit you add to a project, so on this small aplication with one form (two CPP files); you have that many file hits. Please note the stats/cache are reset for EVERY compile. The statisics are: Number of files that the plugin cached as already knowing didn't exist in that location from a prior request Number of files that the plugin cached as already knowing existed from a prior request Total number of file requests. If you subtract the two cache counts from the Total, that will leave you with the total number of _unique_ valid file requests (Using the above numbers a total of 211). Second stats that is the number of requests for the date/time of a file, and how many were requests for dates that _weren't_ cached. If you subtract the two numbers, then result is the number of date/times that were cached that BDS should already have had since it asked for it before. (Sorry the Output say "In Cache" but it sould actually be "Added to Cache". Using the above build numbers meaning a 140 unique file/date requests and a total of 139 duplicate file date requests.

available from the compiler. 2) Help from MS Vissual Studio, such as ms-help://borland.bds5/vclang/html/_pluslang_Bitwise_Exclusive_OR_Operator.htm which includes the inacurate statement: "There are two ways to access the xor operator in your programs: include the header file iso646.h, or compile with the /Za (Disable language extensions) compiler option." Neither of the two ways is the correct way to do so with the Borland compiler - the first method refers to the Dinkumware macros and the second to a switch for the ms compiler. QC Entry 39577

- click the History tab. - Click the Diff tab at the bottom of the History Manager. - The Differences From and To panes at the top of the page shows the file versions that you can compare. - Select the different file versions in both the Differences From pane and the To pane to see the results in source viewer. - At the bottom of the page, source lines that were deleted are highlighted and marked with a PLUS sign - Lines that were added are highlighted and marked with a MINUS sign it should be the other way around. Documentation is correct on this issue: "To compare file versions using the Diff page Using the file that you created in the previous procedure, click the History tab. Click the Diff tab at the bottom of the History Manager. The Differences From and To panes at the top of the page shows the file versions that you can compare.

At the bottom of the page, source lines that were deleted are highlighted and marked with a minus sign ( ). Lines that were added are highlighted and marked with a plus sign (+). The highlighting colors depend on the Code Editor colors. Select the different file versions in both the Differences From pane and the To pane to see the results in source viewer."

I believe an alternate UI for those areas of the settings, or allowing this dialog to resize would make this dialog more usable. The first 4(*) items in the list would give me a significant benefit, because I believe developers use them more frequently. Tools (Environment) Options (Ignoring Together) ------------------------------------------------------------------------------ Significant Benefit (central portion could resize, less scrolling, etc.): - Library Win32 (path lists)* - Environment Variables (variable lists)* - Color (syntax preview)* - Language Exceptions (exception list)* - Native OS Exceptions (exception list) - Event Log (color listbox very cramped) Minor Benefit: - Environment Options (paths) - Object Inspector (color listbox) - Explorer (explorer categories) - CodeGear Debuggers (paths) Little/No Benefit: - Tool Palette - Colors - Type Library - VCL Designer - Editor Options - Source Options (could resize, but large enough now) - Display

Start Delphi 2007 Tools, Options Click around in the options tree and notice some ot the options screens seem cramped in the existing small dialog (see the list in the Description for details) I've attached screenshots of how this dialog looks once it is made resizable, and I think the results are nicer

- Key mappings (could resize, but large enough now) - Code Insight - Debugger Options I'm happy to accept a better/alternate UI instead of resizing, if CodeGear can come up with one that performs the same function in less space, but resizing is the bet option I've imagined so far.

1. Open a readonly .cpp or .h file 2. Right click in code editor, uncheck "Read Only" item 3. Edit the file 4. Save it. Observation: An error message saying the file is read only. Suggestion: When user explicitely removes "Read Only", IDE should smartly ask if user wants to overwrite, instead of popping up an error. Otherwise, user has to go to Windows Explorer, find that file and remove "Read Only" attribute once again. This is inconvenience, especially if a source control system (e.g., CVS) makes all files read only after checking in. Alternatively, it's also ok to disable "Read Only" menu in this case.

Both autosave options enabled, open a complete readonly project except for a .dfm and try to F9 it. This report continues the 41145. Handling readonly .dfm became better but still not there, IMO. QC Entry 48308

Use a small project to demo this stuff, one that uses at least one form (so it has a .dfm) and it is of course already a Delphi 2007 project so it won't need conversion when opened. Make sure you have both AutoSave options enabled (editor+desktop) 1. mark all the files used in the project READONLY, except for a .dfm file and .dproj file 2. now open the project and make some minor change to the source file (.pas) coresponding to the .dfm 3. compile or build the project 4. hit Run expected: .pas file gets saved and project should run actual: .pas file gets saved, plus, you get an error box saying the .dfm file is readonly ... and the worst thing: project does NOT run, and it won't run in the IDE unless you disable the Autosave for editor files. For example the biggest problem is: In the project above, after I changed the .pas file, if the .dfm is readonly I am NOT able to close the project and work something else. Practically you get stuck in the loop Close (or Close All) and the exception box, that's when you answer Yes to the question about saving the project. Well, I maybe changed options for the project and want them saved, so I answer Yes. Thus I can not close the project because it fails on the readonly .dfm (as a workaround I can say No, the second time IDE asks about saving the project - but than, if it did save the project first time, why does it ask again?...)

The IDE doesn't detect that the file is modified. If I instead opens the unit1.cpp file, edits it in an external editor, then the IDE detects this change, but it fails for the main source file.



Description Steps:[QC Short Description] Better troubleshooting help with make/build issues. [QC Description] For trouble shooting build/make issues, consider adding one of the following features: 1) Show the current target/file being worked on in the message pane. (For example, if a compilation error occurs in a header file, the message in the messages pane indicates the header file name, but not the C++/C source file name that is including the header; if the problem is the result of the order of #include's in the source file, how can you find the file that needs to be modified?). 2) Add an extra pane to the project options dialog for viewing the full command line arguments applied for a tool (full project options) (similar to what appears in VC) or to a file (local project options). 3) Generate a makefile equivalent from an IDE project (this is the old BC IDE way of doing things; unfortunately, this utility often failed to keep up with new features added to the IDE).

If one wishes to link to a replacement library calling some of the memory management functions directly (fastmm or other), since the ordinal values for the functions in the replacement library do not necessarily match, one will wind up linking to and calling an incorrect function. The memmgr.lib, should A)preferably be removeable in some obvious fashion (if it is I haven't figured out how), or B)minimally, and maybe even in addition to, provide linking by name, rather than by ordinal. QC Entry 50350

Create a simple vcl forms project. Make sure BDS is configured to show command lines. Build the project. Examine the command line and see that a memmgr.lib is part of the link command, but has not been specified as part of the project. tdump the <bdsinstall>\lib\memmgr.lib, and see that the items are specified as link by ordinal.

The offending part is in lines 12671-12677: '/': if DateSeparator <> #0 then AppendChars(@FormatSettings.DateSeparator, 1); ':': if TimeSeparator <> #0 then AppendChars(@FormatSettings.TimeSeparator, 1); '''', '"': The DateSeparator and TimeSeparator global variables are checked, instead of the fields from FormatSettings, which makes little sense. These should be instead: '/': if FormatSettings.DateSeparator <> #0 then AppendChars(@FormatSettings.DateSeparator, 1); ':': if FormatSettings.TimeSeparator <> #0 then AppendChars(@FormatSettings.TimeSeparator, 1); '''', '"': This not only will cause the separators to be left out in the unlikely chance that the local machine has them null, but in accessing the global variables it undermines the purported thread-safety of the routine.

Description Steps:[QC Short Description] template static data member multiply defined [QC Description] The following report applies to BCB 6.0 update #4: If you unzip the attaced files and do first "make error" then "make noerror", you will see that in the former case, a simple template static data member like template <class T, int N> class Foo { public: static T arr[N]; }; can be multiply defined in an object file depending on whether the first reference to it comes before or after its definition in the source code. When the error appears, the object file contains both a PUBDEF and a COMDEF record for the template static data member, and the PUBDEF record unfortunately contains an incorrect offset. This seems to confuse the linker when creating the final executable. We have also understood that a COMDEF (or actually a VIRDEF record, in the present case) is normally incompatible with the presence of a PUBDEF for the same symbol. But the compiler apperently doesn't comply with this rule. The error has been reproduced in the IDE as well. QC Entry 52639

FileAge may no longer be thread-safe on D2007 (possible access violation) [QC Description] If two threads enter FileAge() simultaneously, it is possible for an access violation to occur on the call to the procedural variable GetFileAttributesExFunc. Initially, GetFileAttributesExFunc points to a function called "GetFileAttributesExPreload": function GetFileAttributesExPreload(lpFileName: PChar; fInfoLevelId: TGetFileExInfoLevels; lpFileInformation: Pointer): BOOL; stdcall; begin GetFileAttributesExFunc := GetProcAddress(GetModuleHandle(kernel32), 'GetFileAttributesExA'); if not Assigned(GetFileAttributesExFunc) then GetFileAttributesExFunc := GetFileAttributesExEmulated; Result := GetFileAttributesExFunc(lpFileName, fInfoLevelId, lpFileInformation); end; Can you spot the race condition? If GetProcAddress returns nil, there's a window in which GetFileAttributesExFunc will be set to nil. If, prior to reaching the "GetFileAttributesExFunc := GetFileAttributesExEmulated" line, a second thread enters FileAge(), the second thread will fail with an access violation when it attempts to call GetFileAttributesExFunc, because it will be jumping into a nil function pointer. This race condition can be eliminated by changing the code to read as follows: function GetFileAttributesExPreload(lpFileName: PChar; fInfoLevelId: TGetFileExInfoLevels; lpFileInformation: Pointer): BOOL; stdcall; var P: Pointer; begin P := GetProcAddress(GetModuleHandle(kernel32), 'GetFileAttributesExA'); if Assigned(P) then GetFileAttributesExFunc := P else GetFileAttributesExFunc := GetFileAttributesExEmulated; Result := GetFileAttributesExFunc(lpFileName, fInfoLevelId, lpFileInformation); end; QC Entry 53645

QC #: Project Date Reported: Area: 54358 Delphi 11/3/2007 IDE\Desktop Layouts Description Steps:[QC Short Description] IDE loses focus after editor window is closed [QC Description] This issue was first introduced in BDS 2006: With the Classic Undocked desktop layout active, if you close the editor window (via Alt+F4 or the window's close button), the keyboard focus in some cases will move away from the IDE and onto another application's window. Only the editor window appears to be affected by this problem. The focus doesn't leave the IDE when other windows like Structure or Object Inspector are closed in the same manner. QC Entry 54358

1. Start the IDE with the Classic Undocked desktop layout selected. 2. Click File | New | VCL Forms Application - Delphi for Win32. 3. Activate the editor window for Unit1, and make sure the Code tab is selected. 4. Click the Windows Start button, then Programs, Accessories, Notepad. 5. With Notepad active, click directly back onto the IDE's editor window. (Do NOT switch to any other windows in between!) 6. Close the editor window by pressing Alt+F4. Answer No when asked to save changes. Actual results: The focus leaves the IDE. Notepad is brought back to the foreground. Expected results: Like in Delphi <=2005, the focus should move to another IDE window. It doesn't really matter which particular one is activated; what's important is that subsequent keystrokes to access menus/etc. are seen by the IDE, and not some other application that unexpectedly popped into the foreground.

Description Steps:[QC Short Description] Cryptic message when an Interface isn't implemented fully [QC Description] Hi, if an interface isn't implemented fully then a misleading (imho) message pops up saying 'E2003 Undeclared identifier: '<identifier name>'. A much more usefull message would be 'Interface <intf name> not implemented fully in class <class name> - <identifier name> is missing'. This will save us many time of hunting for non-existent identifiers especially when we work in teams and especially if the interface definition is in another unit. To make things harder, the 'Undeclared identifier' is used also when we have a typo on an existing one, a syntax error etc. so one cannot track the real cause of the message. QC Entry 55472

QC #: Project Date Reported: Area: 56957 Delphi 1/14/2008 RTL\Delphi\DateUtils Description Steps:[QC Short Description] A Fix for DateUtils Date-Time Compare Functions [QC Description] Programmers have problems with most of the "time-between" functions in Delphi's DateUtils module. The problems (all that I have heard about) are what I call "hidden-value" problems. These problems are due to the fact that the common time values like minute and second do not have exact representations in the TDateTime variable commonly used to store and manipulate date-time values. The TDateTime values would usually be a tiny amount above or below the value that the module's programmer thought his code was working with. Thus the true value of the date-time is "hidden" from the programmer. The long-term, best solution for relieving the programmers' misery is probably to replace the use of TDateTime with something like SQL's TIMESTAMP with its selectable number of seconds decimal fraction resolution or better yet with the SQL TIMESTAMP_WITH_TIMEZONE. However the most expedient solution, which is an easy fix to make and a good one I believe, is to keep the TDateTime variable, but wherever is used for comparisons, convert its value to milliseconds in an Int64 format, similar to what is presently used in the time formatting functions. The Deplhi program sources attached to this QC report are for demonstrating the problem, and testing the millisecond solution to the hidden-time-value problem. The milliseconds used are referenced to the same reference date 0001-01-01 as is used for the SysUtils.TTimeStamp record. The TTimeStamp record and the standard SysUtils' DateTimeToTimeStamp and TimeStampToDateTime routines seem to work perfectly as demonstrated by these tests. This QC report is a duplicate of earlier report #4430; but this newer report contains much more information about the proposed fix and a lot of testing to prove its effectiveness. See QualityCentral report #4430 for more info. In particular, see my comments in that report posted around 2006-12-11 and 2006-12-13. The included module DateUtils_SuggestedChanges_2.pas contains a sample of the DateUtils routines and the suggested modifications and additions for comparison testing. For the reader's further information, here are the QC reports possibly related to DateUtils or this "hidden value" problem: 3240 (C) EndOfADay long format returns value 1 month out 3820 (O) HoursBetween fails to return the good value 4430 (O) Errors using MinutesBetween function 5953 (O) Some functions that use TFormatSettings are not independant of SysLocale & thread's locale 9184 (D) Incorrect Value returned by MinutesBetween function in the DateUtils Unit 27191 (O) DateTime is loosing precision when accessed as Double from DateTime utils functions

To use this program (developed with D7), compile and open it. T_MinutesBetween from QC4430 will test the DateUtils.MinutesBetween function, or if the "Use new and improved" box is check, the T_HiddenTimeValue_2_Unit2 version of MinutesBetween will be used. T_MinutesBetween(X,Y) will run both versions of MinutesBetween and compare the results. ShowExactDateTime will show you the exact value for any date-time that you enter in the upper-left boxes. T_DateTimeToTimeStampAndBack test will test the conversion between TDateTime and TTimeStamp for every millisecond of the whole day specified in the upper-left. T_MilliSecondsToDateTime will test the conversions between Int64 milliseconds and TDateTime by the functions MilliSecondsToDateTime and its inverse around crossovers between days around the date in the upper left. T_MilliSecondsToDateTime displays and tests function by same name. T_DateTimeToMilliseconds displays and tests function by same name.

The entire project has been compiled just prior to observing this behaviour. ADDED: this happens to OVERLOADed methods. QC Entry 57030

- Add the attached form to a new or existing project. - Look at the two similar classes defined there, one with OVERLOADed methods, another without them. - At the end of the form unit you will see the following code, intentionally left unfinished: obj1.AddSQL( // press Ctrl-Shift-Space obj1.a // press Ctrl-Space obj2.a // press Ctrl-Space - go to the end of each line and press the appropriate Code Completion hot keys - you will see that CodeCompletion knows about the overloaded methods (and their parameters), but doesn't show them in the pulldown list. Similar non-overloaded methods in the other class are shown in the list.

QC #: Project Date Reported: Area:57232 C++Builder 1/21/2008 ActiveX\Code Generators\C++

Description Steps:[QC Short Description] Unique names for ActiveX wrapper classes, or ability to choose. [QC Description] Frequently, when importing ActiveX controls, the generated wrapper classes conflict with already registered classes and so generated BPL packages can not be loaded (this is especially common when importing Microsoft Windows Common Controls 1, 2, and 3, with classes such as TUpDown and TToolbar). Current solution is to import then refactor (C++ Rename). Refactoring does not always work (see previous Quality Control report) and always involve trial and error (build, install, refactor, build, install). Suggestion 1: Add an "Ax" (or some other prefix) to the beginning of generated wrapper class names to reduce possibility of imported ActiveX wrapper classes conflicting with preexisting classes. This would generate wrapper class names such as TAxUpDown or TAxListView. Suggestion 2: Allow specification of generated wrapper class names in component import wizard. Automate the process of refactoring the generated code. Suggestion 3: Allow specification of a namespace to put wrapper class names in. Add support to design tool box (and to generated code when using a control from the tool box) for design classes in multiple namespaces. Do not add "using" line for name space, leave that up to the programmer -- generated code would always specify namespaces explicitly. I believe the above suggestions are in order from least to most amount of changes that would have to be made to the component import wizard and design tool box. QC Entry 57232

QC #: Project Date Reported: Area: 58156 C++Builder 2/12/2008 IDE\Code Editor

Description Steps:[QC Short Description] Incremental search does not search entire document. [QC Description] Incremental search does not search the entire document. It only searches from the current cursor position to EOF. There is no option to search entire documents. The message box that says "Search String Not Found" only has an "OK" button -- it is missing the "Continue search at beginning?" question and the "Yes" and "No" buttons. This may be a bug. The same problem appears to occur in normal searches (Search -> Find). Incremental searching in any text editor has two basic functions: 1) To find an occurence of a string in a document, 2) To allow searching to be performed in a quick and convenient manner, without disrupting other tasks (the incremental search feature in Firefox for example; or in emacs which wraps around to the start of the document without prompt at all). All searching features have function #1, "incremental searching" is unique in it's addition of function #2. However, having to apply the described workaround removes both the quickness and convenience of incremental searching. Thus, this is a basic functionality failure of incremental searching.

QC #: Project Date Reported: Area: 58864 Delphi 2/28/2008 VCL\Core VCL Classes Description Steps:[QC Short Description] TComboBox.Items.IndexOf cannot find empty string [QC Description] TComboBox.Items.IndexOf does not work correctly for the empty string. Even if the combo box's items do contain an empty string, IndexOf('') will incorrectly return -1. This is inconsistent with the behavior of other TStrings descendants. See Steps. QC Entry 58864 // Francois Piette The behaviour is the same in Delphi 7 so the issue exists for years. I attached the sample project.

(See attached project) 1. Create a new form. 2. Drop a TComboBox, a TButton, and a TMemo onto the form. 3. Add a private method to the form class, and implement it: private procedure TestStrings(AStrings: TStrings); procedure TForm1.TestStrings(AStrings: TStrings); var Idx: Integer; begin AStrings.Clear; AStrings.Add('Foo'); AStrings.Add('Bar'); AStrings.Add(''); AStrings.Add('Baz'); Memo1.Lines.Add('Using ' + AStrings.ClassName + ':'); for Idx := 0 to AStrings.Count - 1 do begin Memo1.Lines.Add(Format(' Item ''%s'': index %d', [AStrings[Idx], AStrings.IndexOf(AStrings[Idx])])); end; Memo1.Lines.Add(''); end; 4. Add a handler for the button's OnClick event, and implement it: procedure TForm1.Button1Click(Sender: TObject); var StringList: TStringList; begin Memo1.Lines.Clear; TestStrings(ComboBox1.Items); StringList := TStringList.Create; try TestStrings(StringList); finally FreeAndNil(StringList); end; end; 5. Run the program and click the button. Expected: the output for the TComboBoxStrings and the TStringList should be identical. Both should be able to find the empty string that's in the list. Actual: TStringList.IndexOf is successfully able to find '', but TComboBoxStrings.IndexOf fails, incorrectly returning -1 even though '' is in the list. Actual output: Using TComboBoxStrings: Item 'Foo': index 0

Item 'Bar': index 1 Item '': index -1 Item 'Baz': index 3 Using TStringList: Item 'Foo': index 0 Item 'Bar': index 1 Item '': index 2 Item 'Baz': index 3

Description Steps:This Should be fixed for both C++ & Delphi. [QC Short Description] Inability to over-ride imported component names can cause conflict [QC Description] When importing a type library, under at least some previous versions of C++ Builder, it was possible to over-ride the names of the components that would be created. This allows name conflicts to be avoided. However, with C++ Builder 2007, the "Component" > "Import Component" > "Import a type library" wizard tells you what the names are going to be, and does not provide any mechanism to override the names - even if they are clearly in conflict with existing components. For example, when importing the "Microsoft ADO Ext 2.8 for DDL and Security", the suggested names include TTable and TColumn. In at least one previous C++ Builder version, it was possible to override these names (for example, to TADOXTable and TADOXColumn) and so allow the "components" to install without any name conflicts. As it now stands, no ability to override names exists, no conflicts are reported and the conflictingly named "components" are simply silently omitted when the package is installed. It is not possible to simply generate the files and then change the names in the wrapper as the wizard pre-builds the corresponding DCR file, and this has the conflicting component names compiled in.

QC #: Project Date Reported: Area: 61658 Delphi 5/1/2008 RTL\Delphi\Pascal Strings Description Steps:[QC Short Description] Unicode AnsiLastChar and AnsiStrLastChar can step past first character [QC Description] When the Unicode versions of AnsiLastChar and AnsiStrLastChar are passed a string containing only a trailing surrogate character (#$DC00..#$DFFF), the functions return a pointer one character before the beginning of the string. The ANSI versions of the functions don't do this when passed only a trail byte. Also, similar to the ANSI versions, I believe they ought to verify that a leading surrogate (#$D800..#$DBFF) actually exists before decrementing Result. That way, a test like: StringEndsInX := (AnsiLastChar(S)^ = 'x'); won't be tricked into returning True if S = 'x'#DC00. Fixes: function AnsiLastChar(const S: UnicodeString): PWideChar; var Len: Integer; begin if S = '' then Result := nil else begin Len := Length(S); Result := @S[Len]; if (Len > 1) and (Result^ >= #$DC00) and (Result^ <= #$DFFF) and(Result[-1] >= #$D800) and (Result[-1] <= #$DBFF) then Dec(Result, 1); end; end; function AnsiStrLastChar(P: PWideChar): PWideChar; var Len: Integer; begin Len := StrLen(P); Result := @P[Len - 1]; if (Len > 1) and (Result^ >= #$DC00) and (Result^ <= #$DFFF) and(Result[-1] >= #$D800) and (Result[-1] <= #$DBFF) then Dec(Result, 1); end; Optimization notes: - For smaller code size, I changed the "Length(S) = 0" check in AnsiLastChar to "S = ''". - I'm storing the string length in a local variable (register) to avoid making multiple calls to Length/StrLen.

The issue appears to be related to dbxase30.dll (Sybase ASE), as the same test application does not produce a memory leak if the TSQLConnection is instead associated with the 3rd party dbexpca400.dll (from Peter Sawatzki) and connected to an AS/400 database. Including "ReportMemoryLeaksOnShutdown:=true;" in the test application FormCreate, does not report any memory leaks on shutdown, despite the application having consumed and not released additional memory for each ExecSQL call. The leaked memory is also not released even after Free'ing the TSQLQuery object that was used to invoke the ExecSQL call (perhaps further confirming the issue exists with dbxase30.dll?). The memory is only released upon termination of the application. QC Entry 62562

TDBXWeaverBugsSuite.Native.DB.Test.exe connection=aseconnection -s:TestRaid_260834 -or- Simple Delphi 2007 test application source is attached which reproduces the problem. This establishes runtime TSQLConnection and TSQLQuery component, and attempts to truncate then write 1000 unique records to a database table called dse_trpprc, which comprises two char fields (trp, prctyp). This can be easily changed to any table name / field names in the source. Note that using VCL components at design time, or creating runtime components for TSQLConnection or TSQLQuery makes no difference.Example output from the dbxase30.dll ASE connection using the test application is as follows (demonstrating a memory leak): -- Start Mem: 3,988 K - End Mem: 6,204 K - Consumed: 2,216 K Start Mem: 6,212 K - End Mem: 6,216 K - Consumed: 4 K Start Mem: 6,216 K - End Mem: 6,220 K - Consumed: 4 K Start Mem: 6,220 K - End Mem: 6,228 K - Consumed: 8 K Start Mem: 6,228 K - End Mem: 6,232 K - Consumed: 4 K Start Mem: 6,232 K - End Mem: 6,240 K - Consumed: 8 K Start Mem: 6,240 K - End Mem: 6,244 K - Consumed: 4 K Start Mem: 6,244 K - End Mem: 6,252 K - Consumed: 8 K etc. -- Conversely, if the TSQLConnection is changed to use dbexpca400.dll / dbxadapter30.dll to connect to an AS/400 database (instead of Sybase ASE), the following output is logged (noting no memory leak - only the initial component memory consumption): -- Start Mem: 3,256 K - End Mem: 6,504 K - Consumed: 3,248 K Start Mem: 6,508 K - End Mem: 6,512 K - Consumed: 4 K Start Mem: 6,512 K - End Mem: 6,516 K - Consumed: 4 K Start Mem: 6,516 K - End Mem: 6,516 K - Consumed: 0 K Start Mem: 6,516 K - End Mem: 6,516 K - Consumed: 0 K Start Mem: 6,516 K - End Mem: 6,516 K - Consumed: 0 K Start Mem: 6,516 K - End Mem: 6,516 K - Consumed: 0 K Start Mem: 6,516 K - End Mem: 6,516 K - Consumed: 0 K Start Mem: 6,516 K - End Mem: 6,516 K - Consumed: 0 K Start Mem: 6,516 K - End Mem: 6,516 K - Consumed: 0 K etc. --

QC #: Project Date Reported: Area:63172 Delphi 6/11/2008 IDE\Code Editor\Error Insight Description Steps:[QC Short Description] Error Insight incorrectly identifies errors when there are none (when global variable and member names match) [QC Description] There have been several reports of Error Insight underlining an 'error' with red squiggles, and adding an entry to the 'Errors' list - when there is no error and the code compiles correctly. Traditionally they've been hard to track down and provide steps. I've finally managed to identify complete, simple steps to provoke Error Insight into misbehaving - at least in the latest version of Tiburon. Basically, if your code creates an instance of an object which has a published property with the same name as a previously declared global (object) variable, Error Insight will incorrectly display errors. See steps... QC Entry 63172

1. Create a new VCL Forms application. Add an OnShow handler to the main form - like this: procedure TForm1.FormShow(Sender: TObject); begin Application.ProcessMessages end; 2. Add a new unit to the project (File/New/Unit - Delphi for Win32). Make it declare an object with a published property, with the same name as the 'Application' global variable refered to in step 1 - like this: unit Unit2; interface type TTest = class private fApplication: string; published property Application : string read fApplication write fApplication; end; implementation end. 3. Add a reference to Unit2 from the 'interface' section of the application's main form unit, and modify the application's main form object so that it declares a private variable of type TTest. The full source for the application's main form unit should now look like this: unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, Unit2; type TForm1 = class(TForm) procedure FormShow(Sender: TObject); private fTest : TTest; { Private declarations } public { Public declarations } end; var Form1: TForm1; implementation {$R *.dfm} procedure TForm1.FormShow(Sender: TObject); begin Application.ProcessMessages end; end. 4. Notice how when you do this, the 'ProcessMessages' in the Application.ProcessMessages line gets underlined with a red squiggle, and an error appears "'string' does not contain a member function named "ProcessMessages" 5. If you comment out the 'fTest:TTest' line, the message disappears. If you un-comment it, it reappears, and so on until you're bored.

To achieve proper alignment, the empty string structure was moved into a "const" record. As noted in the source, however, this has the undesirable side effect of making the string writable. This now executes successfully: var S: string; begin S := ''; PChar(S)^ := 'x'; end; whereas in all previous Delphi versions, it raised an AV immediately. Without the AV, it becomes much more difficult to track down what is trying to overwrite the character, and all but impossible for a program to continue operating normally following such an attempt. There are two other ways the alignment problem could be solved without making the string writable:

63328 Delphi 6/15/2008 Compiler\Delphi\Code Generation/Optimization

Description Steps:[QC Short Description] _EnsureXXXStrings should be moved to the C++ side, better Delphi string performance [QC Description] The _EnsureXXXString calls should be moved to the C++ side so they do not harm all Delphi developers. These calls slow down every single string access and they are only required if the string comes from the C++ code. So, why not move all these _EnsureXXXString calls into the generated .hpp files? Every function that has a string parameter could call a stub that does the _EnsureXXXString call and then calls the actual Delphi function. This way all Delphi developers would be let alone with this performance hit. QC Entry 63328

(by Pierre le Riche) Consider the following example, used to count the number of occurrences of a given character in a string: function CountChars(const MyStr: AnsiString; TheChar: AnsiChar): Integer; var i: Integer; begin Result := 0; for i := 1 to Length(MyStr) do begin if MyStr[i] = TheChar then Inc(Result); end; end; This code compiles to 40 bytes under Delphi 2007 and executes in 171 clock cycles with an input string of length 10. Compare this to the same scenario under Tiburon: It compiles to 141 bytes and takes 351 clock cycles for the same input. So, the example above is 3.5 times larger and it takes twice as long to execute when compiled with Tiburon. If there was a compiler directive to switch off those _EnsureXXXString calls the performance would be similar.

QC #: Project Date Reported: Area: 64258 Delphi 7/9/2008 IDE\File Handling Description Steps:[QC Short Description] "View Unit" displays extra entries for some files [QC Description] This issue can be seen in complicated project groups when several projects use different files with the same name placed in different folders. For example, in my current project group I have 3 projects including "database.pas" file. Each project uses its own file placed in a separate folder. For this case "View Unit" displays 4 entries for "database.pas". This happens not with all files with coinciding names. Only some of them have this extra entry. QC Entry 64258

It is necessary to check "All files in project group" in order to see this issue.



Description Steps:

[QC Short Description] Missing "View Source" CTRL+V shortcut in Project Manager popup menu [QC Description] In the Project Manager popup menu for a project is the shortcut CTRL+V for "View Source" missing - it is only "&Quelltext anzeigen" and not "&Quelltext anzeigen Strg+V". Well the shortcut does only work if you have selected project item, but it is a difference to the english version. A "nice" side effect of the missing shortcut is that you can add any actually existing file to the project. If you do that with the .dpr or .dproj file and try to remove it then you get this error --------------------------- Fehler --------------------------- Das Hauptmodul des Projekts kann nicht entfernt werden. --------------------------- OK Details >> --------------------------- QC Entry 64276

Steps for missing shortcut: - start german version of RAD Studio 2007 - create a new VCL application - select the project entry (Project1.exe) in the project manager - make sure the project source is closed - press CTRL+V expected: the project source would be opened actual: nothing happens - show the popup menu for the project entry in the project manager - look for "&Quelltext anzeigen" expected: the text is "&Quelltext anzeigen Strg+V" or "... Ctrl+V" (depends on the OS language) actual: the text is only "&Quelltext anzeigen" Steps for bad side effect: - start german version of RAD Studio 2007 - create a new VCL application - save the application for example as c:\CopyMeToClipboard.dproj - put "c:\CopyMeToClipboard.dproj" into the clipboard - select the project entry (CopyMeToClipboard.exe) in the project manager - press CTRL+V expected: nothing happens or the project source would be opened actual: CopyMeToClipboard.dproj will be added to the project - try to remove "CopyMeToClipboard.dproj" from the project --------------------------- Fehler --------------------------- Das Hauptmodul des Projekts kann nicht entfernt werden. --------------------------- OK Details >> ---------------------------

In fact, they shouldn't be needed at all. Yes, I know that even though the parameter is declared as UTF8String, it could technically have a different payload, which could be Unicode or another code page. However, that should only happen if the programmer calls SetCodePage() explicitly. It should be the programmer's responsibility to make sure the payload eventually matches the declared type. I compare this with types that are integer ranges, e.g.: type MyRange = 42..123456; Technically, a variable of type MyRange can hold any integer. But it shouldn't. The compiler does not constantly try to coerce MyRange variables to fit the type. Instead, I have the option to turn on range checking to have the compiler help me catch bugs with incorrect MyRange values. Similarly, I'd like to have a compiler option that would insert an assertion at the start of each function to check that the payload the string passed to function matches the declared type. In my Test() procedure above, the assertion would be: Assert(StringCodePage(S) = CF_UTF8, 'Payload for S must be CF_UTF8'); For functions that return a string, the compiler would insert the same assertion at the end of the call to ensure that the returned string matches the declared type. RawByteString would be exempted from these checks. Also, using InternalLStrFromUStr does not guarantee Length() to return the correct result. If S is passed a CP1252 string instead of a UTF8 string, and the string includes non-ASCII characters, the

returned length will be different. E.g. if my function uses Length() to calculate how many bytes to allocate to save a string in UTF-8 format, but the string is encoded as CP1252, my function will not allocate enough bytes if the string includes characters >= #$80. If another function then writes to that buffer, and that function uses SetCodePage to forcibly convert to UTF-8, I'll be stuck with a mysterious buffer overrun. If instead the compiler added an assertion to my function, the assertion would have caught the incorrect payload. The bug would be obvious, which I could fix by either making the caller pass a proper UTF-8 string, or I could change my function to accept RawByteString, and convert it to UTF-8 as needed inside the function.

[QC Description] ! Please reinvestigate. The problem is that the icons wrap incorrectly, while it looks like each row contain 12 components, when you click them you notice each row only contain 11. ! When resizing the tool palette the icons wrap to a new row 1 pixel after the tool palette think they do. When this happens clicking on a component in the second and third row will select the wrong component. In the attached screenshot ToolPaletteError1, the first 11 components in each category works as intended, the rest does not. Note how several components show the mouseover look, eventhough the cursor is on the row below. This only happens on the second row.The Cursor itself is over the TActionManager icon, eventhough the Hint says it's over TBalloonHint. In the Additional category: 1) The last clickable component on row 1 is TSplitter. 2) The first component of row 2 is TStaticText, not the TLinkLabel you expect. 3) The first component of row 3 is TDockTabSet, not the TTrayIcon you expect. In the Win32 category, to show it's not the missing icons: 1) The last clickable component on row 1 is TMonthCalendar. 2) The first component of row 2 is TTreeView, not the TListView you expect. I've added 3 new screenshots to further illustrate this, it's easily reproducable. I keep the cursor over the TFlowPanel in all three screenshots. [beforewrap.png]

Steps A: 1. Dock the Project Manager, Tool Palette and Messages to the right edge of the IDE. 2. Set all three to autocollapse. 3. Set Tool Palette properties to: Button size: Medium Show button captions: Uncheck Vertical flow layout: Check Vertical category captions: Uncheck Bold captions: Check Caption only border: Check Use +/- icons: Check Auto collapse categories: Uncheck Show button hints: Check Persistent search filter: Check Always show designer items: Uncheck Show palette wizards: Check Lock palette reordering: Uncheck 4. Create a new VCL application. 5. Collapse all but the Additional Tool Palette category. 6. Resize the tool palette so TCheckListBox are on the first row of the Additional category. It should look like beforewrap.png. 7. Now resize it (to be smaller) so it's just about to wrap, notice how you get an empty row just as it wraps, that's the bug. It should look like buggedwrap.png and afterwrap.png.

This shows the tool palette one pixel before it wraps. [buggedwrap.png] Tool palette is now 1 pixel narrower, there's a new empty row in the additional category, it contains 3 components, but the icons don't wrap to show it. [afterwrap.png] Tool palette is now 2 pixels narrower compared to beforewrap.png, and everything works again. QC Entry 64634



Description Steps:[QC Short Description] The project view does not show the file directories. [QC Description] The project view does not show the absolute location of each file as it used to do so in Delphi 7 and previous versions. QC Entry 64640

The project view does not show the absolute location of each file as it used to do so in Delphi 7 and previous versions. This is important feature that was lost after D 7. It makes it difficult to easily ménage different projects, and find problems with files located at wrong places. 1. Open a Delphi or C++ Builder project. 2. If you set the project manager to Flat as example it will show the files the same way as in Delphi 7, but it will not display the location of the file in a separated column next to the file name. This makes managing projects and finding wrong locations very difficult.

QC Entry 64898 Added by Sysop <<<<<<<<<<<<<<< This issue still exists in Delphi 2010. Please workaround of QC report. >>>>>>>>>>>>>>>

Create a new VCL forms application and add a single button with an OnClick handler. Add the following code to the implementation section, then run the application and click the button. type TMyControl = class(TCustomControl) procedure WMSize(var Message: TWMSize); message WM_SIZE; end; procedure TMyControl.WMSize(var Message: TWMSize); begin inherited; Canvas.TextWidth('ABC') end; procedure TForm1.Button1Click(Sender: TObject); var C: TMyControl; begin C := TMyControl.Create(Self); C.Visible := False; C.Parent := Self; C.SetBounds(0, 0, 100, 100); C.Canvas.Lock; C.Canvas.TextWidth('DEF'); C.Canvas.Unlock; C.Free end; In the sample code the window handle hasn't been created when TextWidth('DEF') is called, so the GetDeviceContext call in TControlCanvas.CreateHandle has to create it, which triggers the WM_SIZE message and the nested TControlCanvas.CreateHandle call. The canvas is locked to keep it in the CanvasList until it's all the way out; if it isn't then TWinControl.MainWndProc can remove it, which masks the bug.


QC #: Project Date Reported: Area: 64919 Delphi 7/29/2008 RTL\Delphi\Date - Time Description Steps:[QC Short Description] DateSeparator is not used by DateToStr for some locale settings [QC Description] (checked on WinXP SP3 Ru) There is a problem with DateSeparator in some environments. The problem is that DateTimeToString expects '/' as date separator in ShortDateFormat: '/': // <--- fixed separator for date if DateSeparator <> #0 then AppendChars(@DateSeparator, 1); ':': if TimeSeparator <> #0 then AppendChars(@TimeSeparator, 1); But when you change date format in Windows, the current separator is used inside format string (not '/' as expected by DateTimeToString), for example: 'yyyy.mm.dd' but not 'yyyy/mm/dd'. So, actually DateSeparator is not used in format string at all. Please, see "Steps to reproduce" to reproduce the problem. Note that ':' is always used in ShortTimeFormat regardless of TimeSeparator. So, this problem is not occured for time (only for date). I suggest to add something like: ShortDateFormat := StringReplace(ShortDateFormat, DateSeparator, '/', [rfReplaceAll]); to GetFormatSettings and GetLocaleFormatSettings routines in SysUtils.pas.

(JJS: If you set the date separator in the windows regional settings, the attached console app can easily reproduce the issue.) 1. Open regional settings in windows and setup the short date format: 'yyyy.mm.dd'. The date separator is '.'. 2. Create new VCL application, write: procedure TForm1.FormCreate(Sender: TObject); begin Caption := DateToStr(Now); // ShortDateFormat is 'yyyy.mm.dd', DateSeparator is '.' end; 3. Run it. You will see '2008.07.29' in form's caption (as expected). 4. Modify it: procedure TForm1.FormCreate(Sender: TObject); begin DateSeparator := '-'; Caption := DateToStr(Now); // ShortDateFormat is 'yyyy.mm.dd', DateSeparator is '-' end; 4. Run it. You will see '2008.07.29' in form's caption. But the expected value is '2008-07-29'. 5. Modify it: procedure TForm1.FormCreate(Sender: TObject); begin DateSeparator := '-'; Caption := DateToStr(Now); // ShortDateFormat is 'yyyy/mm/dd' - see unit's initialization below, DateSeparator is '-' end; initialization

And the floating edit box for the rename is in a VERY odd state, apparently split into two halves at the point I'm changing it (e.g. if I'm changing "project2.lib" to "project12.lib" it splits into "project1" and "2.lib", which you can navigate between with left and right arrow keys). QC Entry 65073

Open the attached project group (projects\projectgroup1) In project1.exe, use F2 in the tree and try renaming project2.lib to Project12.lib Screenshot attached of what I see! In the rename edit window, note the "2.lib". If try scrolling left, it "flips" to saying just "Project1" - scroll right and it flips back!

Description Steps:[QC Short Description] No option to disable alphabetic ordering of files in a project [QC Description] C++ Builder has long needed the OPTION to alphabetically order the files in a project - however it has now gone too far, and not got any OTHER option. We need the user ordering back... Even better, allow separate ordering within file type - e.g. main project cpp, res file, then normal project files, then libraries... <sysop> I consider it to be a usability essential to be able to put the files I never edit - lib, res, main project file, etc. at the bottom of the PM list so that they do not take up valuable screen space in the portion of the PM that is always visible without scrolling. Alpha reordering should be an on-demand optoin only IMO. Not averse to having the current implementation as an option, but my preferences in order are: 1. Ability to control order of display in PM - Essential 2. Ability to Alphabetize on demand - Nice addition 3. Ability to alphabetize a selected file type - Even better, but maybe not worth the effort and complication 4. Automatic alphabetization within grouped file types - Only way I might consider an using automatic option, and only if I could specify the order of the groups (.cpp at top, everything else below) 5. Automatic alphabetization as currently implemented - would never use this by choice and think it should be available only if there is a demonstrable demand for it. I consider this a serious impediment to my use of the PM, and under no circumstanced should it be the only option. QC Entry 65679

Just create a project with several files - and try to reorder it manually. You get the drag and drop graphics, but the order stays strict alphabetic.

When this option is enabled the OI divider should never move around except when it needs to obey the left and right OI margins. The motivation for this request is as follows: I usually set the position of the OI divider quite far to the left such that the names of the properties are barely visible and the bulk of the space is available for the property values (which does tend to require more space than the property names). From time to time I may have to drag the OI wider to see the full property value, and then it is not useful when the divider also moves to the right. QC Entry 66167

66382 C++Builder 9/4/2008 VCL\Emulation Classes Description Steps:[QC Short Description] Interface functions cannot be overwritten in derived VCL class [QC Description] When writing a VCL class that derives from an interface, it is not possible to overwrite an interface function in a descendant. This is onlya problem in VCL classes; it works as expected for classes that don't derive from TObject. The following code illustrates the problem. First, we declare an interface: class __declspec (uuid ("{D58EBD98-BEC7-474F-A827-A4CCA0511841}")) IMyInterface : public IInterface { public: virtual void foo (void) = 0; }; Now we want to implement it using a normal C++-style class: class Base { int i; // some non-empty base class }; class Derived1 : public Base, public IMyInterface { // this is just a trivial implementation of the IUnknown functions. _CPPINTF_IMPL_QUERYINTERFACE_BEGIN _CPPINTF_QUERYINTERFACE (IMyInterface) _CPPINTF_IMPL_QUERYINTERFACE_END _CPPINTF_IMPL_ADDREF_RELEASE public: virtual void foo (void) { std::printf ("Derived1::foo()\n"); } }; In addition, we override the definition of foo() in a descendant: class Derived2 : public Derived1 { public: virtual void foo (void) { std::printf ("Derived2::foo()\n"); } }; This works as expected. Now let us try something similar with a VCL class: class VCLDerived1 : public TInterfacedObject, public IMyInterface { // simple redirection to TInterfacedObject::_AddRef() etc. _CPPINTF_IMPL_QUERYINTERFACE_INHERITED_VCL _CPPINTF_IMPL_ADDREF_RELEASE_INHERITED_VCL public: virtual void foo (void) { std::printf ("VCLDerived1::foo()\n"); } }; class VCLDerived2 : public VCLDerived1 { public: virtual void foo (void) { std::printf ("VCLDerived2::foo()\n"); } }; In class VCLDerived1 : public TInterfacedObject, public IMyInterface{ _CPPINTF_IMPL_QUERYINTERFACE_INHERITED_VCL _CPPINTF_IMPL_ADDREF_RELEASE_INHERITED_VCL public: virtual void foo (void) { std::printf ("VCLDerived1::foo()\n"); }

- download the attachment - compile it with bcc32 -WCV qc66382.cpp - run it - Expected output: Derived2::foo() VCLDerived2::foo() Derived2::foo() VCLDerived2::foo() - Actual output: Derived2::foo() VCLDerived2::foo() Derived2::foo() VCLDerived1::foo() Yet worse, if you remove the definition of foo() in Derived1 and VCLDerived1, you receive Derived2::foo() Pure virtual function called

}; class VCLDerived2 : public VCLDerived1 { public: virtual void foo (void) { std::printf ("VCLDerived2::foo()\n"); } }; In this case, every call to VCLDerived2::foo() via an IMyInterface pointer will actually call VCLDerived1::foo(). This implies that it is not possible to partially implement an interface in a class without writing virtual wrapper functions (your program dies with the message "Pure virtual function called" if you try this).

QC #: Project Date Reported: Area: 66881 Delphi 9/17/2008 IDE\Help Description Steps:[QC Short Description] Delphi 2009 Type Library Options page help wrong [QC Description] The Type Library options page (in Tools | Options) has changed for both Delphi and C++Builder. Unfortunately, there's a little problem with that. First of all, pressing Help when looking at the Delphi Type Library page brings up the C++Builder Type Library page (which you also get if you click on Help from the C++Builder Type Library page, so at least it's consistent). The bigger problem is that the help page is still Delphi 2007 specific: the new options are not documented, yet. The first two groups (Ignore special CoClass Flags when importing, and SafeCall function mapping) are still covered, as well as the Source Refreshing option, but the Type Library Editor and RIDL Options are not. There are three RIDL options: - Lookup referred type libraries in the registry - Store Unicode data as UTF8 in type library - Check for UTF8 data in the type library There are two final Type Library Editor options: - Refresh implementation when renaming type library - Refresh implementation when .ridl file is saved Fortunately, these options are relative easy to understand (the only thing that’s not clear is the alternative for UTF8 data. QC Entry 66881

Start the Tools | Options dialog in Delphi 2009, go to the Delphi Type Library page. Pressing Help when looking at the Delphi Type Library page brings up the C++Builder Type Library page (which you also get if you click on Help from the C++Builder Type Library page, so at least it's consistent). Also note that the actual help pages contain incomplete information (from Delphi 2007).

Open parameters Meaningful only for code compiled supporting huge strings, and is provided for backwards compatibility with early versions of Delphi and CodeGear Pascal. This option, (equivalent to $P) controls the meaning of variable parameters declared using the string keyword in the huge strings disabled (equivalent to {$H-}) state. When disabled (equivalent to {$P-}), variable parameters declared using the string keyword are normal variable parameters, but when enabled (equivalent to {$P+}), they are open string parameters. Regardless of the setting of this option, the openstring identifier can always be used to declare open string parameters. Default = True Strict var-strings This option (equivalent to $V directive) is meaningful only for Delphi code that uses short strings, and is provided for backwards compatibility with early versions of Delphi and CodeGear Pascal. The option controls type on short strings passed as variable parameters. When enabled (equivalent to {$V+}), strict type is performed, requiring the formal and actual parameters to be of identical string types. When disabled (equivalent to {$V-}) (relaxed), any short string type variable is allowed as an actual parameter, even if the declared maximum length is not the same as that of the formal parameter.

QC #: Project Date Reported: Area: 67793 Delphi 2/21/2007 VCL Description Steps:[QC Short Description] PNG-compressed 256x256 application icons don't display properly in Vista [QC Description] When using an icon that includes a 256x256 PNG-compressed image for Windows Vista along with smaller sizes as the application icon, the 48x48 image is displayed on the desktop and in Windows Explorer when Vista is configured to shows large icons. This makes the icons of Delphi applications look smaller than all the other icons, as if the developer used an XP-style icon. The problem is only visible on Windows Vista, since earlier versions of Windows don't support icon sizes beyond 48x48 anyway. The problem only occurs with compressed icons. Using an uncompressed 256x256 icon works fine, but results in a significant and needless increase in file size. QC Entry 41098

1. Create a new project 2. In Project Options, select sample_icon_vistacompression.ico as the application icon 3. Compile. 4. Put both sample_icon_vistacompression.ico and the compiled .exe in the same folder. 5. View that folder in Windows Explorer on Vista 6. Click the Views button and select Extra Large Icons in Explorer Expected: sample_icon_vistacompression.ico and the .exe are shown using the same icon Actual: sample_icon_vistacompression.ico is shown full size, but the .exe's icon is small

Description Steps:[QC Short Description] Simple type Char now maps to WideChar [QC Description] In the documentation for simple types, URL: ms-help://embarcadero.rs2009/devcommon/simpletypes_xml.html it reads "The generic character type is Char, which is equivalent to AnsiChar on Win32, and to Char on the .NET platform. Because the implementation of Char is subject to change, it's a good idea to use the standard function SizeOf rather than a hard-coded constant when writing programs that may need to handle characters of different sizes." Since the default string was changed to unicode, Char no longer maps to AnsiChar but WideChar. QC Entry 68345

QC #: Project Date Reported: Area: 68497 Delphi 11/1/2008 IDE\Build Tools Description Steps:[QC Short Description] Binary image base setting problem [QC Description] In the [project options] - [Delphi Compiler] - [Linking] page have two entries: "Image Base", and "set base address for relocatable image". They seems to have identical meaning to the IDE (both generate -K parameter for dcc32), but they handle input differently. The "Image Base" entry accepts hex number, but the "set base address for relocatable image" does not - a '$' symbol is needed in order to put a hex numer in that entry. In addition, if a hex number is set in the "set base address for relocatable image", the IDE would generate bad -K option, with two '$' in front of the hex number. QC Entry 68497

1. Create a new project. 2. Go to [project options] - [Delphi Compiler] - [Linking] page 3. In the "Image Base" entry, type: 10A00000 3. In the "set base address for relocatable image" entry, type: 10A00000, then try to move the focus away. The IDE will complain '10A00000' is not a valid integer value. 4. Change the input data to $10A00000, and close the property window, save the project. 5. Compile this project, and check the dcc32 commandline. It looks like: <path>\dcc32.exe ... -K10A00000 ... -K$$10A00000 ... Notice it has two -K options, and the second one has two extra '$'. However, the compilation does finish sucessfully, and the produced binary has the intended base address. This could be either the compiler ignores the second -K, or it is coded to handle malformed parameter gracefully.

Description Steps:[QC Short Description] Incorrect BSTR management in Event Handlers with non-reference String parameters [QC Description] When generating an ActiveX Control (OCX) from a VCL component, any VCL event handler that has String parameters that are not passed by reference are freeing temporary BSTR objects incorrect at runtime.QC Entry 70212

1) File | New | Other | C++Builder Projects | ActiveX | ActiveX Library 1) File | New | Other | C++Builder Projects | ActiveX | ActiveX Control 2) Select TStringGrid (or any component that has event handlers with String reference parameters) 3) Press OK The following type of code is generated: void __fastcall TTestImpl::SetEditTextEvent(TObject *Sender, int ACol, int ARow, const UnicodeString Value) { BSTR TempValue; TempValue = WideString(Value).Copy(); Fire_OnSetEditText((long)ACol, (long)ARow, TempValue); delete TempValue; // <-- wrong way to free a BSTR!! } The last line is not freeing the BSTR correctly. The SysFreeString() function must be used instead. WORKAROUND ============= Change the generated code to call the SysFreeString() function instead of the 'delete' operator: void __fastcall TTestImpl::SetEditTextEvent(TObject *Sender, int ACol, int ARow, const UnicodeString Value) { BSTR TempValue; TempValue = WideString(Value).Copy(); Fire_OnSetEditText((long)ACol, (long)ARow, TempValue); // delete TempValue; SysFreeString(TempValue); // <-- here } Or, stop using BSTR values directly at all and let the WideString class do all of the work: void __fastcall TTestImpl::SetEditTextEvent(TObject *Sender, int ACol, int ARow, const UnicodeString Value) { Fire_OnSetEditText((long)ACol, (long)ARow, WideString(Value).c_bstr()); }

QC #: Project Date Reported: Area:70842 C++Builder 1/25/2009 IDE\Code Editor\Syntax Highlighting

Description Steps:[QC Short Description] Files without extension should be syntax-highlighted as C++ headers [QC Description] This was improved in Cogswell, but apparently, the IDE just has an incomplete "whitelist" of files without extension that are C++ headers. IMHO, a better approach would be to use syntax highlighting for all files that reside in a subdirectory of one of the include paths. QC Entry 70842

- Create a new C++ project, add this lines: // ----- #include <string> #include <cstring> // ----- - Now Ctrl+Enter each of the files (or use the context menu instead). Exp.: both files are shown with C++ syntax highlighting Act.: only <string> is syntax-highlighted. (If you have TR1 in your path, <string> refers to $(CG_BOOST_ROOT)\boost\tr1\tr1\string instead of $(BDS)\include\dinkumware\string. No highlighting in that case.)


QC #: Project Date Reported: Area: 70905 Delphi 1/27/2009 Database Description Steps:[QC Short Description] TVarData.VString interpreted as UnicodeString, while it contains a pointer to an AnsiString [QC Description] A search in DBCommon for the symbol 'VString' (a member of TVarData), results in 8 occurances of this construct : "string(TVarData(Value).VString)". Since 'string' now means UnicodeString, this construct interprets an AnsiString as UnicodeString, without any compiler magic in between. Possibly the new string-header helps preventing errors, but at the very least this is a syntactic error. PS: Don't mix this up with TVarRec.VString: PShortString, it's TVarData.VString: Pointer that's handled wrong. QC Entry 70905

Search in the RTL/VCL code for all 'VString' occurances. Notice that in Variant.pas all TVarData.VString are cast to an AnsiString. Now notice that DBCommon (and other units) do a cast to 'string', which effectively means a cast to 'UnicodeString'.

Description Steps:[QC Short Description] Using old style Objects in D2009 fails [QC Description] I have a lot of old BP7 code which uses the old-style Object syntax. It has been working fine (except for error insight) with all versions of Delphi until now, but having gone through the process of de-ANSIing the code to get it to compile I find it crashes as soon as it uses a virtual method call. I have prepared a short test program that runs (after removing the D2009 specific code) in BP7 but fails in D2009. I can get it to run in both either by not initialising the object's field or making the Virtual method static. QC Entry 71723

The following code compiles but fails to run. The problem seems to be with corruption of the VMT after field initialisation. program testD2009; {$APPTYPE CONSOLE} uses SysUtils; Type PObject1 = ^TObject1; TObject1 = Object FCount : Integer; Constructor Init; Procedure Add; virtual; { removing virtual allows the program to run } end; Type PObject2 = ^TObject2; TObject2 = Object(TObject1) Constructor Init; end; Constructor TObject1.Init; begin { Commenting out this assignment allows the program to run. It also runs if Procedure Add; is not Virtual.

I disagree for the following reasons: - cv qualifiers apply to objects only, not to classes. As can be seen, a static method may be invoked through a const or volatile object reference. - The only difference between a class method and a static method (leaving the option of virtual class methods apart) is that the class method can be bound to an object at runtime whereas the static method is bound at compile time. There is no difference in how they access static member variables of their classes. - Neither static methods nor class methods can be declared as const or volatile.

QC #: Project Date Reported: Area: 73014 Delphi 4/15/2009 IDE\Open Tools API Description Steps:[QC Short Description] Better support for designing dockable IDE forms [QC Description] It would be nice if you would deliver the "Units and Forms required to create Dockable IDE Forms" together with the ToolsAPI source, because otherwise one can hardly design dockable IDE windows. Still with it wouldn't be that easy (-> see steps) and if you have a better solution in mind then this is of course also acceptable. I've recently created a new expert and in order to take advantage of the default dockable layout and the desktop save feature I made the main form a dockable IDE window. I found some information how to do this in the following DN articles "Opening Doors: Getting Inside the IDE" http://dn.embarcadero.com/article/21114 "Creating a Web Search Wizard using the OpenTools API." http://dn.embarcadero.com/article/26418 and downloaded the following from Code Central, because I found the "link" to this in the first article. "ID: 14529, Units and Forms required to create Dockable IDE Forms"http://cc.embarcadero.com/Item/14529 The Zip-file of CC 14529 contains the following files BaseDock.dfm BaseDock.pas DeskForm.dfm DeskForm.pas DeskStrs.pas DeskUtil.pas DockForm.dfm DockForm.pas DockToolForm.dfm DockToolForm.pas DummyDockProj.dpr DummyDockProj.res IDEDockGroup.bpg These files should be updated to match the recent IDE and file formats (.groupproj instead of .bpg) and so on and should be added to a sub folder of the ToolsAPI source - for exam. ...\RAD Studio\x.y\source\ToolsAPI\DockableFormStubs (Maybe you find a better name...) To make clear that these files are not supposed to be compilable (someone expected that in article 21114) adding something like {$MESSAGE Fatal } could help. For DeskForm this could look like this unit DeskForm; {$MESSAGE Fatal 'This file cannot be compiled. This stub exists to give you the possibility to design IDE forms.'} interface Open question: Are such messages localizable? QC Entry 73014

today with Delphi 2009: - somehow manage to find "ID: 14529, Units and Forms required to create Dockable IDE Forms" http://cc.embarcadero.com/Item/14529 - start Delphi 2009 - open DummyDockProj.dpr - add a new form inherited from "DockableToolbarForm" * File | New -> New * select page "Delphi Projects" | Inheritable Items * select "DockableToolbarForm" - save this form - remove this form from the DummyDockProj.dpr project - add your existing wizard package/DLL expert project to the current project group (DummyDockProj.dpr should stay in this project group) - add the prior saved form to your wizard package/DLL expert -> now you can design your form ... - whenever you later plan to work on your dockable form then make sure that DummyDockProj.dpr is part of the project group

But: it is already private! Tf_Farbpalette = class(TForm) BitBtn1: TBitBtn; procedure BitBtn1Click(Sender: TObject); private Abbruch : boolean; procedure SaveValues; public end; Abbruch can be made private it claims. As I've found out now this problem also repeats with other units/classes and is also there when the private section only contains one object reference as field. QC Entry 73025

QC #: Project Date Reported: Area: 73047 Delphi 4/16/2009 Modeling\Audits Description Steps:[QC Short Description] Possibly wrong warning about uninitialized global var [QC Description] QA audits warns me about one global variable in a unit which is uninitialized. It's a integer and in the initialization section of this unit it gets initialized. The only thing I could think about is if another unit uses this one and could have access to the var before the initialization section of the unit is run. Can this be? If not this check isn't yet intelligent enough in my eyes.

1. create some application as follows: Unit QATest; interface procedure DoIt; implementation var myglobgalvar:TObject; procedure DoIt; begin myglobalvar.Free; end; initialization myglobalvar:=TObject.Create; end. 2. enable modeling support and run QA audits 3. see it complain that myglobalvar never gets initialized

QC #: Project Date Reported: Area:73441 C++Builder 4/28/2009 Compiler\C++\Front End\Object Generation

Description Steps:[QC Short Description] Compiler generates faulty code when allocating arrays of Delphi classes [QC Description] For some reason, the compiler's front end permits the allocation of arrays of Delphi classes. However, the compiler doesn't really support the construction of arrays of Delphi classes. It just allocates 12 bytes (which is 8 bytes too few anyway because of the hidden fields - i.e., the compiler should invoke TObject::InstanceSize()) and calls the RTL function _vector_new_ldtc_() to initialize the objects - but _vector_new_ldtc_() was designed solely for C++-style classes and therefore runs into AVs when applied to a Delphi class. IMHO, the compiler should not allow the construction of Delphi-class object arrays in the first place, but if it does, it should at least a) allocate enough memory (by querying InstanceSize()) and b) call the constructors in the right way. QC Entry 73441

QC #: Project Date Reported: Area:73566 Delphi 5/2/2009 RTL\Delphi\File Management Description Steps:[QC Short Description] In SysUtils, Buffers of length MAX_PATH in the Unicode world are dangerous QC Entry 73566

From SysUtils.pas function ExpandFileName(const FileName: string): string; var FName: PChar; Buffer: array[0..MAX_PATH - 1] of Char; begin SetString(Result, Buffer, GetFullPathName(PChar(FileName), Length(Buffer), Buffer, FName)); end; When ExpandFileName is called with a path longer than MAX_PATH you get back a string full of nulls. Unicode filepaths can be up to 32k TChars. eg (\\?\Dir\SubDir\..........\FileName) See: Naming a File (ms-help://embarcadero.rs2009/FileIO/fs/naming_a_file.htm) <QUOTE> The Unicode versions of several functions permit a maximum path length of approximately 32,000 characters composed of components up to 255 characters in length. To specify that kind of path, use the "\\?\" prefix. Note The maximum path of 32,000 characters is approximate, because the "\\?\" prefix can be expanded to a longer string, and the expansion applies to the total length. For example, "\\?\D:\<path>". To specify such a UNC path, use the "\\?\UNC\" prefix. For example, "\\?\UNC\<server>\<share>". These prefixes are not used as part of the path itself. They indicate that the path should be passed to the system with minimal modification, which means that you cannot use forward slashes to represent path separators, or a period to

represent the current directory. Also, you cannot use the "\\?\" prefix with a relative path. Relative paths are limited to MAX_PATH characters. When using the API to create a directory, the specified path cannot be so long that you cannot not append an 8.3 file name. The shell and the file system may have different requirements. It is possible to create a path with the API that the shell UI cannot </QUOTE> The entire RTL/VCL needs to be checked for any other situations where MAX_PATH is used to define the lenght of a buffer, then determine if any changes are required.

Running on Windows XP Service Pack 3 (Spanishs): If a VCL application has a GroupBox and uses a DLL built with the VCL option checked, when the application closes an Access Violation exception is produced. Added by Sysop <<<<<<<<<<<<<<<<<< 'DELAY LOAD DLLs' is a CORRECT WAY to fix your issue. This issue occurs with Delphi application(.exe, .dlls), but Delphi does not support DELAY LOAD DLLs option. If you have a .exe and .dlls which depend on runtime packages of VCL(.BPLs), you have to use DELAY LOAD DLLs option. The reason is that, in you case, VCL resources have been initialized by the .DLL's startup code, because OS loads the .DLL file before .EXE. It must be initialzied by .EXE's startup code instead of .DLL's. One typical wrong result of this issue is ICON images of MainForm and Application which are not initialized correctly... So, if your .DLL does not need VCL features, please create the .DLL without VCL support. As a result, the .DLL does not initialize VCL resources. P.S.

QC #: Project Date Reported: Area:75180 Delphi 6/23/2009 VCL\Win 32 Controls\TListView

Description Steps:[QC Short Description] TCustomListView.RecreateWnd causes too many unnecessary events (i.e. OnDeletion, OnInsert, etc...) [QC Description] - Outline - TCustomListView.RecreateWnd causes too many unnecessary events. (i.e. OnDeletion, OnInsert, etc...) When RecreateWnd is called, Items on TCustomListView are all deleted and inserted again. But, Delete method, InsertItem method and etc always call the event which is related with the method. So, this problem is caused. - Problems - * If Item has custom data on Data property, you will free its memory on OnDeletion event: If RecreateWnd calls OnDeletion, it will delete the data that should not be deleted. * Users cannot detect that RecreateWnd is called: RecreateWnd is called by too many methods. So it is too difficult for them to write the code with considering RecreateWnd. * Too many events will be called: So users cannot judge what event is called properly or not. - Right behavior -

1. Create a new VCL Form Application. 2. Drop a TListView and a TButton onto Form. 3. Turn Checkboxes on TListView to True. 4. Write following code on TButton.OnClick. -Code- procedure TForm1.Button1Click(Sender: TObject); var NewItem: TListItem; begin NewItem := ListView1.Items.Add; NewItem.Caption := 'hogehoge'; NewItem.Checked := True; NewItem.Selected := True; NewItem.ImageIndex := 0; if ListView1.ViewStyle = vsReport then begin ListView1.ViewStyle := vsIcon; end else begin ListView1.ViewStyle := vsReport; end; end; 5. Write following code on TListView.OnDeletion. procedure TForm1.ListView1Deletion(Sender: TObject; Item: TListItem); begin ShowMessage('OnDeletion'); end; 6. Run and click the button. exp: The message dialog does not appear. act: The message dialog appears. In this case, following events will be called. But they are all unnecessary. OnDeletion OnChanging OnChange OnSelectItem OnCreateItemClass OnItemChecked OnInsert

If ControlState includes csRecreating, TCustomListView does not call these events. See Steps, Workaround and Attachments QC Entry 75180

Description Steps:[QC Short Description] DCC should emit an empty default constructor for records [QC Description] If a constructor with arguments exists, a C++ doesn't implicitly generate a default constructor. Other than Delphi, C++ does not differentiate between classes and records (struct), thus the same rule applies to records. Because of this, DCC should emit an empty default constructor - which BCC would generate anyway - to records if these records have non-default constructors. I.e., this code // ----- type TMyRecord = record constructor Create (Foo: Integer); end; // ----- is represented by this code in the header file: // ----- struct TMyRecord { public: __fastcall TMyRecord(int Foo); }; // ----- Much better would be: // ----- struct TMyRecord { public: __fastcall TMyRecord(void) {} // <-- __fastcall TMyRecord(int Foo); }; // ----- The attached test case demonstrates how the current behavior can cause broken headers.

QC #: Project Date Reported: Area:76020 Delphi 7/22/2009 RTL\Delphi\Other Classes\TEncoding

Description Steps:[QC Short Description] TEncoding.ASCII property is broken on some systems [QC Description] The TEncoding.ASCII property uses codepage 20127 exclusively. Not all OS versions support that codepage, though. When not available, the TEncoding.ASCII property should fallback to codepage 1252 instead. This bug exists in Tiburon as D2009 as well. QC Entry 76020

Addressing this issue can be handled inside of the TMBCSEncoding constructor, ie: constructor TMBCSEncoding.Create(CodePage: Integer); begin // FCodePage := CodePage; Create(CodePage, 0, 0); end; constructor TMBCSEncoding.Create(CodePage, MBToWCharFlags, WCharToMBFlags: Integer); var LCPInfo: TCPInfo; LError: Boolean; begin FCodePage := CodePage; FMBToWCharFlags := MBToWCharFlags; FWCharToMBFlags := WCharToMBFlags; LError := not GetCPInfo(FCodePage, LCPInfo); if LError and (FCodePage = 20127) then begin FCodePage = 1252; LError = not GetCPInfo(FCodePage, LCPInfo); end; if LError then raise EEncodingError.CreateRes(@SInvalidCodePage); FMaxCharSize := LCPInfo.MaxCharSize; FIsSingleByte := FMaxCharSize = 1; end;

QC #: Project Date Reported: Area: 76395 C++Builder 8/4/2009 CodeGuard Description Steps:[QC Short Description] CodeGuard and TCppWebBrowser cause application crash on startup [QC Description] Enabling CodeGuard on an application that uses a TCppWebBrowser component within it causes an application crash with an empty message box and no diagnostic information as to the cause. In my case, I had moved a large application with many units from CB2006 to CB2009. The application ran without problem, but when I enabled CodeGuard, the application would not even start (the cryptic details are below), and a breakpoint on the first line of WinMain was never reached. I spent many hours searching for the cause of the problem, tearing out parts of the application until I found it. This will occur in any application that uses either a TCppWebBrowser or TWebBrowser anywhere in it; even including the .h file of a unit that uses one of these components will cause the problem. Note that the following thread was posted in the forum in January, 2009, without response: https://forums.codegear.com/thread.jspa?messageID=66367&tstart=0 Unlike that thread, I do not get a codeguard log indicating what happened. The .cgl file does not have anything useful. This is a basic functionality failure because CodeGuard is an important part of CB2009, and is useless if there is a TCppWebBrowser anywhere in the application, since the application crashes without giving a reason why or any reason to suspect that the TCppWebBrowser (as opposed to any one of the thousands of other components) is the problem.

[QC Description] If a primitive data type parameter is declared as const after being prototyped as non-const, the compiler ignores that parameter's const-ness and permits it to be modified anyway. Parameters declared as const in this fashion are somewhat unique in that the const-ness isn't part of the function's signature, but the compiler should still enforce it within that function.

QC #: Project Date Reported: Area:76508 C++Builder 8/7/2009 IDE\Code Editor\Formatting Description Steps:[QC Short Description] One initializer per line option [QC Description] When writing the definition of a constructor, one common coding idiom is to initialize one base or class member per line, rather than hoist them all onto the same line. This could be another code formatter option under line-breaks E.g. given struct MyClass : Base1, Base2 { MyClass( int a, int b, int c ); int m; }; I would want to write: MyClass::MyClass( int a, int b, int c ) : Base1() , Base2(a, b) , m(c) { } Tweaks others might be interested in with the same layout include: whether the comma goes at the end of the previous line, or start of the next (as I prefer) whether the opening brace goes on new line, or after last initializer whether opening brace is indented with the list if on a new line QC Entry 76508

It is optional if a single statement should be written inside {} as well, and coding conventions vary. If would be helpful if the code formatter could enforce project rules for this - so options that a single statement should: i/ never be put in {} ii/ always be put in {} iii/ respect the existing source This might be configured as a general rule about controlled expressions, or it might be configured per-keyword. QC Entry 76511

[vk] Not all should be fixed!!! 1. case i/ "never be put in {}" can be very dangerous 2. case iii/ "respect the existing source" - the current behaviour 3. case ii/ "always be put in {}" - we can add such option in the form from Together 6.1 "Surround simple body by curly braces" autoformat.java.controlStatement.forceBodyBraces = false | true | ifOnNextLine Defines how Together will treat a simple body in control expressions.(A simple body is not surrounded by curly braces.

while the AVs went away! and I could shutdown repeatedly without problem. I tired to open a different project in the IDE being debugged and voila: AVs again. Next step: I ran bds.exe in the debugger by defining it as host app for the MMX addin dll project without actually loading the add-in dll (temp unregistered it). And yes: AVs at shutdown - as long as the project opened in the IDE is relatively "new". Once the opened project is "known" I can shutdown OK. Doing the same thing outside the debugger does not show any noticable error msgs. So why is this a shopwstopper? Because these (invisible) AVs can cause 3rd party addins to crash afterwards which in that case does show error msgs. Another hint: something inside the IDE makes the "known" state persistent: once the problem is gone I can consistently restart / shutdown without AVs The stack traces point at some thread still running at shutdown causing the AV. Probably the thread collection the "persistent state" ? Below are

QC #: Project Date Reported: Area: 76866 C++Builder 8/19/2009 IDE\Project Management Description Steps:[QC Short Description] Bogus missing package prompt [QC Description] What I have in my project group is one main project that depends on several run-time packages (and some DLL projects), which are all in the same project group. All is fine when I have the corresponding bpi files for the main project. However, when I do a clean of all the projects, the next time I try to rebuild all projects, the IDE will prompt me for the location of the missing packages. This is simply incorrect - the reason I'm hitting rebuild all is so that I'd be able to rebuild the packages which can then be used by the main project. If I ignore the prompt by canceling through the dialogs (a lot of them), I can get everything to build except the main project. The IDE must have taken it out of the list even though I hit cancel. I had to close the project and reopen for the IDE to reset its state. Then do another build. CB2007 did not exhibit this problem at all. So far my impression of CB2010 is that its IDE is worse than CB2007. QC Entry 76866

Open TestGroup.groupproj under Test\ folder. Change package1.bpl to a runtime only package. Activate tester.exe project. Hit Ctrl+F9. Missing package prompt shows. That's dumb, considering the reason user hit Ctrl+F9 in the first place is so that they could build the package which the IDE complains is missing!


QC #: Project Date Reported: Area: 76879 C++Builder 8/20/2009 Compiler\C++\Back End Description Steps:[QC Short Description] BCC doesn't correctly emit the updated type info [QC Description] The type info structures in TypInfo.pas have been updated to support the new RTTI features, primarily attributes.

It is understandable that BCC doesn't fully support the new RTTI features such as attributes right now, but it should at least zero out the new fields - right now the type info generated by BCC is simply wrong, and all code that tries to read in all type info fields simply crashes. To demonstrate the failure, I've attached a test case that simply reads out and skips above fields. It works fine for DCC-built type info but, as expected, it runs into AVs when consuming BCC-generated type info. In addition, once QC's #76875 and #76877 are fixed, I think Rtti.pas will form another good test case for this problem. QC Entry 76879

Description Steps:[QC Short Description] SysUtils.TUncertainState declaration isn't translated to C++ correctly [QC Description] For some reason, the declaration of the TUncertainState enum in SysUtils isn't represented correctly in SysUtils.hpp. TUncertainState is declared with $SCOPEDENUMS ON, which usually results in "enum class" declarations instead of plain "enum" declarations. This is also what happens if SysUtils is compiled manually (DCC32 -JPHN SysUtils.pas), but the header supplied with build 3513 contains "enum TUncertainState". The problem itself isn't really noteworthy, but I think the cause might be worth investigating. QC Entry 76883

Open SysUtils.hpp, search the declaration of TUncertainState. Exp.: // ----- enum class TUncertainState { Maybe, Yes, No }; // ----- Act.: // ----- enum TUncertainState { Maybe, Yes, No }; // ----- [NOTE: See my comments in the resolution: It's related to -JPHNE vs. -JL. The latter seems to treat enums always as unscoped when emitting .hpp files :(

Code in D2010 is in TStreamReader itself, but otherwise unchanged. Suggested code: function TStreamReaderHelper.DetectBOM(var Encoding: TEncoding; Buffer: TBytes): Integer; var LEncoding: TEncoding; begin LEncoding := nil; Result := TEncoding.GetBufferEncoding(Buffer, LEncoding); if LEncoding <> nil then begin if (LEncoding = TEncoding.Default) and (Encoding <> TEncoding.Default) then // If no BOM detected default to UTF-8 Encoding := TEncoding.UTF8 else Encoding := LEncoding; end else ;// Leaving Encoding parameter alone FDetectBOM := False; end; QC Entry 76894

QC #: Project Date Reported: Area: 76972 C++Builder 8/25/2009 IDE\File Handling Description Steps:[QC Short Description] IDE fails to create form if TAnimate->Filename is invalid [QC Description] If a form has a TAnimate control with it's filename property set to a non-existent file and Active set true, then the IDE fails to create the form when the unit is loaded. For me this occurred when I tried to move the project to a new machine and the filename specified contained an invalid path. Because the form is not created there is no way to fix the error and no access to the form's history so that a revert can be done. I had to exit the IDE and manually revert all the unit files to a date prior to the inclusion of the filename. I'd suggest that the IDE flags the error to the user and then sets the Active property to false so that at least the form is accessible and can be fixed. QC Entry 76972

Create a new VCL forms application Drop a TAnimate on the form Point the filename to an existing .AVI file. Set Active to true. Save and close the project. Delete the .AVI file Open the project.

The setup: Unit2 contains TBar, a non-Generic descendant from TObjectList<T>. (TObjectList<TObject> in particular) type TBar = class(TObjectList<TObject>); Unit1 uses Unit2 and attempts to create an instance of TBar in Button2's OnClick handler. var Bar: TBar; begin {$INLINE AUTO}

Bar := TBar.Create; Bar.Free; end; Attempting to compile the project will trigger the I12307 on the Bar := TBar.Create; line. Removing (or disabling) the $INLINE AUTO directive will allow the file to compile successfully. It appars to only affect the call site itself, because setting Inline to Autoin the project options also causes the compiler error. If the class declaration is in the same unit, the error is not thrown, as can be seen by TFoo and its corresponding usage in the demo project.QC Entry 77121

QC #: Project Date Reported: Area:77221 C++Builder 8/31/2009 Compatibility\BCB<->Delphi Description Steps:[QC Short Description] The Rtti unit does not work with runtime packages disabled [QC Description] When "Build with runtime packages" is disabled the Rtti unit is completely useless. When enabled the Rtti unit is just very buggy. QC Entry 77221

Create a new VCL application with the following code somewhere, eg. in a button OnClick: TRttiContext LContext; TArray__1<TRttiType*> Types = LContext.GetTypes(); You also need to include Rtti.hpp at the top of the file. This works when "Build with runtime packages" is enabled and Types gets filled with a list of all types. But when runtime packages is disabled the list is empty.

[NOTE FROM BRUNEAU] ======================= This is really a request for a new feature for the C++ compiler and linker. See the attach file that describes what the C++ compiler and linker would need to do.


QC #: Project Date Reported: Area:77226 Delphi 8/31/2009 AddOn\Interbase components Description Steps:[QC Short Description] IBX Not reporting correct Interbase Error Number [QC Description] I think I have run into a bug in the latest version of IBX that came with Delphi 2010. IBX is returning a different error code under a specific situation than it used to in D2009 Basic details; I was creating a trigger, and the trigger purposely was referencing an invalid column in the database. Under D2009, IBX properly reported a -206 error (column not found error). Now under D2010 it reports 66 (Use Open for Select Statement). I think I have found the change in IBX that caused this. It may have other side effects on other IB errors as well..(not sure how bad this actually is - for me its bad though) In IBSql.pas TIBSQL.Prepare; ... if Assigned(Encoding) then bt := Encoding.GetBytes(FProcessedSQL.Text + #0) else bt := BytesOf(AnsiString(FProcessedSQL.Text) + #0); try Call(FGDSLibrary.isc_dsql_prepare(StatusVector, TRHandle, @FHandle, 0, PByte(bt), Database.SQLDialect, nil), True); except SetLength(bt, 0); end; As you can see, the call to isc_dsql_prepare, which generates the proper interbase error (-206), when it raises this exception, it gets gobbled up by the try/except which sets the length of the bt buffer to 0. I really think this should also re-raise the exception generated by isc_dsql_prepare. The older IBX code does not have this try/except, sothe interbase exception -206, makes it out to the outside callers. If I am correct here, then I have a problem that I am going to have to figure out a workaround for until a fix is made. QC Entry 77226

Create an interbase table to a database: CREATE TABLE TESTTABLE ( FIELD1 INTEGER NOT NULL, FIELD2 INTEGER NOT NULL); Now, Using IBX components, IBDatabase, IBTransaction, IBQuery, attempt to execute the following DDL query: CREATE TRIGGER TESTTRIGGER FOR TESTTABLE ACTIVE BEFORE INSERT POSITION 0 AS BEGIN IF ((NEW.SEQ IS NULL) OR (NEW.SEQ = 0)) THEN begin /* Do something dumb just for illustation*/ new.seq = 100; end; END When executing this DDL query, IBX should report a -206 column not found error. But it just generates a 66 (use Open for a Select Statement)


QC #: Project Date Reported: Area: 77285 Delphi 9/2/2009 Compiler\Delphi\Interfaces Description Steps:[QC Short Description] TComponent interface functions "redirected" to TInterfacedObject when a class helper for TComponent (descendant) exists

Steps by USc: - save the file at the end of the steps - dcc32 ClassHelperIntf.dpr - execute ClassHelperIntf.exe and see the output is "PASS" - dcc32 -DWITHCOMPONENTCLASSHELPER

[QC Description] TComponent Interface functions like _AddRef or _Release are "redirected" to TInterfacedObject when a class helper for TComponent or a TComponent descendant exists. This is regression from D2007, but it happened already in D2009. This issue can lead to unexpected behavior, because components are destroyed when the interfaces are released. -> see steps Original short description: Corrupted component interfaces Original description: I am running into a very strange bug with interfaces. Unfortunately it seems that i can only reproduce this on my product which is about 200000 lines of codes making impossible to supply a code for reproducing. I'll try to describe what happens in pseudo code bellow Type a = class(tcomponent) b = class(a, IAnyInterface) var myobject: b; implementation in my code i a getinterface call on objects eg myobject.getInterface(IAnyInterface, ivar) The problem is that in function TObject.GetInterface(const IID: TGUID; out Obj): Boolean; the statement if Pointer(Obj) <> nil then IInterface(Obj)._AddRef; Results to a call to TInterfacedObject._AddRef insteand of TComponent._AddRef. This behavior occurs only with 2010 while 2007 and 2009 work as expected. This causes the object to be freed and crash the app. My application dosen't work with d2010 while worked as expected with d2007 and d2009 QC Entry 77285

ClassHelperIntf.dpr - execute ClassHelperIntf.exe expected: output is PASS actual: output is FAIL #1 Additional test to "see" whats happening - start Delphi - open ClassHelperIntf.dpr - enable "Use debug .dcus" in the project options or compile with the RTL source - add WITHCOMPONENTCLASSHELPER as conditional define or remove the dot in line five - compile ClassHelperIntf.dpr - start the app - step through the following lines "FooComponent.GetInterface(IFooInterface, I)" "I := nil;" and see TInterfacedObject._AddRef and TInterfacedObject._Release are executed program ClassHelperIntf; {$APPTYPE CONSOLE} {.$DEFINE WITHCOMPONENTCLASSHELPER} uses Classes; type IFooInterface = interface ['{68A52E11-7139-4B66-AB44-21AF8E85B81A}'] end; TFooComponent = class(TComponent, IFooInterface) destructor Destroy; override; end; {$IFDEF WITHCOMPONENTCLASSHELPER} TBarComponentHelper = class helper for TComponent end; {$ENDIF WITHCOMPONENTCLASSHELPER} var FooComponent: TFooComponent; I: IFooInterface; ComponentAlive: Boolean; destructor TFooComponent.Destroy; begin ComponentAlive := False; inherited Destroy; end; begin FooComponent := TFooComponent.Create(nil); try if FooComponent.GetInterface(IFooInterface, I) then begin ComponentAlive := True; I := nil; if ComponentAlive then WriteLn('PASS') else WriteLn('FAIL #1'); end else WriteLn('FAIL #2'); except FooComponent.Free; end; end.

DataSnapDM.native.db.test.exe connection=mssqlconnection -s:TestRaid_272727 -or- 1) Create a Datasnap server with a connection to a MSSQL database 2) Expose the TDBXConnection to the client (e.g. ServerConnection=TServerMethods3.GetConnection in the parameters) 3) Create a client application that has a TSQLQuery that passes the SQL to the server 4) Create a SQL SELECT statement that returns two blob fields e.g. SELECT blob1, blob2 from Table1 Test the size of the fields like this: var Stream1, Stream2: TStream; begin Stream1 := SQLQuery1.CreateBlobStream(SQLQuery1.FieldByName('blob1'),

bmRead); ShowMessage(IntToStr(Stream1.Size)); Stream2 := SQLQuery1.CreateBlobStream(SQLQuery1.FieldByName('blob2'), bmRead); ShowMessage(IntToStr(Stream2.Size)); Then adjust the SQL to reverse the blob fields SELECT blob2, blob1 from Table1 In my case the first test return the correct sizes, but in the second test blob2 size becomes 0. (This worked correctly in Delphi2009 Datasnap)


QC #: Project Date Reported: Area: 77303 Delphi 9/3/2009 Database\DBExpress Description Steps:[QC Short Description] Impossible to use temp tables in mssql [QC Description] An application originally made with D2007 uses dbExpress to connect to MSSQL. For some functionality, it creates temporary tables and fills these with data in consecutive statements on the same connection in the same (implicit) transaction. This worked great in D2007, but the same code fails in D2010. It looks like changes to the mssql dbexpress driver in between versions has broken this functionality. (Don't know about D2009.) Using explicit transactions does not help. Dmitry Arefiev suggested the driver might be using sp_execute statements internally, which would explain the behaviour because that would create a new context for each statement thus failing to recognize temp tables made in another context and therefore already dropped. This is really basic functionality for our app and a showstopper for porting it to D2010 (unfortunately, because I really like it even better than D2007). QC Entry 77303

TDBXWeaverBugsSuite.Native.DB.Test.exe connection=mssqlconnection -s:TestRaid_272730 -or- Create a new application and drop a TSQLConnection and a TButton. Connect the TSQLConnection to a MSSQL server by setting the Driver, Host and a Database. To the button.OnClick handler attach this code: SQLConnection1.ExecuteDirect('create table #TestTemp (something integer)'); SQLConnection1.ExecuteDirect('insert into #TestTemp (something) values (1)'); Expected: both statements run fine. If this program is made using D2007, it does. If made with D2010, this application fails on the 2nd statement with the SQL error "Invalid object name '#TestTemp' ". D2007 uses dbxmss30.dll. D2010 uses dbxmss.dll. If I make the D2007 version use dbxmss.dll, it fails too. Unfortunately, it doesn't work the other way round.

Description Steps:[QC Short Description] message pump is now much slower than older versions [QC Description] Delphi 2010 has a message pump which is much slower than previous version (Actually the change appeared silently in D2009 update 3). The reason for slow down is clear: TApplication.ProcessMessage now filter queued messages to first extract mouse messages then do the processing. Looking at the code, the behaviour is exactly the same as the previous version which had not that message filtering. To say it in other words (sorry for my bad english), extracting the mouse messages is completely useless. The only impact is making the message pump much slower ! OK, there is another slight impact: mouse messages are handled before

See attached zip file containing a sample program. See _readme.txt in the zip file.

any other message and this could cause strange result because in many applications, the order of message processing is important (this is why there is a queue !). The impact is not noticable in normal situation because the message queue is almost empty. But under stress condition, removing mouse messages from the queue takes a lot of time. The application then consume a lot of CPU and is much less responsive if not completely frozen. I don't understand why the message pump code has been changed after so many years of good services. That change makes existing applications much slower and impose a new design (a worker thread to have another message queue). I think this is completely unecessary. btw: the offending code is line 9757 in forms.pas in D2010: MsgExists := PeekMessage(Msg, 0, WM_MOUSEFIRST, WM_MOUSELAST, PM_REMOVE); See attached file for demo program showing the issue. The zip file contains a screen dump showing D2010 and D2007 versions side by side with task manager. QC Entry 77410

QC #: Project Date Reported: Area: 77448 Delphi 9/7/2009 VCL Description Steps:[QC Short Description] TRichEdit.RegisterConversionFormat causes exception [QC Description] On Delphi 2009, TRichEdit.RegisterConversionFormat does not work (the function passed to the method will never be called), and simply calling the method causes an exception when the program exits. The problem appears to be in the FreeConversionFormatList method called in the ComCtrls finalization section, and specifically the AppendConversionFormat method, which is using the code: ConversionFormatList.Add(Pointer(@NewRec));

Simply creating a TRichEdit instance and then calling the RegisterConversionFormat method with appropriate parameters demonstrates the bug. The attachment contains a program for both Delphi 2009 and Delphi 5 which demonstrates the problem. To see the problem, run the program, click the button on the main form, then close the program. An access violation occurs when the program exits if compiled with Delphi 2009, but not with Delphi 5.

when it looks to me like it should be this: ConversionFormatList.Add(Pointer(NewRec)); Not only does this fail to register the conversion function with the correct address, so it never gets called, but it screws up the heap when the list is de-allocated.

Description Steps:[QC Short Description] TTrayIcon.ShowBalloonHint() does not work correctly on pre-Vista systems [QC Description] TTrayIcon.ShowBalloonHint() does not work correctly on pre-Vista systems. This is because the ShellAPI.TNotifyIconData record is larger in D2010 than it is in D2009, and TTrayIcon is setting the TNotifyIconData.cbSize member to the full byte size, which is only appropriate for Vista and later systems. TTrayIcon needs to be updated to check the actual OS version and adjust the cbSize value accordingly, and then not use fields that are outside that size when appropriate.

The fact that not Create or StartNew were used made this stopwatch low res, and that produces the wrong result, which should have been something like 00:00:01.4790000 (1.5 seconds) I assume the problem lies in the factor 1000 in TStopwatch.GetTimeStamp, which should probably be 10000.

QC#52996 has mark closed but I still can replay the problem in Delphi 2010. I create a new issue here and alter the test case to show the problem more clearly. We may use TParams.ParseSQL to create a list of parameter items of SQL with parameter. For example: UPDATE MYTABLE SET Name1=:Value1 WHERE Name1=:Value1 AND Name2=:Value2 TParams.ParseSQL will return 3 param items where 1st and 2nd param item has same param name. In this case, TParams will attempt to use TParam.FParamRef (private property) to link the 2nd param item to 1st param item at some point. Refer to VCL source code (DB.pas). If you assign a value to Params[0], you will get the same value in Params[1] and vice versa. If the SQL is: UPDATE MYTABLE SET Name1=:Value1

WHERE Name2=:Value2 AND Name1=:Value1 You may notice the 1st and 3rd param items are repeated in this case. If you assign a value to Params[0], you will not get the value in Params[2]. This happen if there are repeated param item falls on the last item in TParams collection. Added by Sysop <<<<<<<<<<<< If 3 different paramters are used as below, this issue does not occur.

However, starting with C++Builder 2009 and continuing in C++Builder 2010 the overhead of a do-nothing VCL DLL project has risen by many times the previously acceptable size. QC Entry 77723

Consider a do-nothing VCL DLL project. The project is created, modified to specify output directory and to build standalone (turn off packages and runtime library).

TDBXFulcrumBugsSuite.Native.DB.Test.exe connection=ibconnection -s:TestRaid_272900 -OR-

TParams.ParseSQL does not correctly parse named parameters when the parameter name is quoted and contains a space. For instance, when the SQL statement 'SELECT * FROM test10a WHERE lastname = :"Last Name" ' is passed to TParams.ParseSQL, the parameter that is created is named "Last". This is a regression from behavior in Delphi 2009. QC Entry 77724

The following code will produce the errant behavior: procedure TForm1.FormCreate(Sender: TObject); oQuery1 : TQuery; begin oQuery1 := TQuery.Create( self ); oQuery1.SQL.Clear; oQuery1.SQL.Add( 'SELECT * FROM test WHERE lastname = :"Last Name" ' ); ShowMessage( 'Parameter Name = ' + oQuery1.Params[0].Name ); end; The output of the above code is "Last", when it should be "Last Name".

The apparent cause it that variant is not getting loaded in the register correctly. Looking in Invoke() inside of RTTI.pas you will find PutArg() whichrequires the datasize to be returned or it places the item on the stack. TValue.DataSize returns 0 if a variant is stored in it. var vTest : Variant; vTest2 : TValue; begin vTest := '123'; vTest2 := TValue.From<Variant>(vTest); Writeln(SizeOf(Variant)); Writeln(vTest2.DataSize); end. Changing function TValue.GetDataSize: Integer; to return 4 for a variant allows this test case to work. .... tkMethod: Exit(8); tkInt64: Exit(8); tkVariant : Exit(4); else Exit(0); end; .... I don't believe this would be correct however, I think that DataSize may need to return the size of the data correctly, which would mean changing the TValue.GetDataSize from: ... tkArray, tkRecord, tkString : Exit(IValueData(FData.FHeapData).GetDataSize); ... tkArray, tkRecord, tkString,tkVariant : Exit(IValueData(FData.FHeapData).GetDataSize); Doing this, however would require changes on the Invoke() side to pass the parameters correctly.

Then compiler by some reason generates code to copy everything located at [ebp - $08] to [ebp - $04] and then when its generate code to call TTestWrapper.DoStuff it passes ebp - $04 to it instead of ebp - $08 then later at hidden finalization there is following code: 00406D6B 8D45F8 lea eax,[ebp-$08] 00406D6E 8B15BC6A4000 mov edx,[$00406abc] 00406D74 B902000000 mov ecx,$00000002 00406D79 E8E2ECFFFF call @FinalizeArray

Compiler generates code which finalizes the record and its exact copy twice. as result this function increase reference count once and decrease it twice and TTestWrapper.FValue destroyed.

Description Steps:[QC Short Description] Unable to clear a boolean option from an option-set in CB2010 [QC Description] Sometimes it is necessary to clear a boolean option from a set which means I don't want to change the value of the boolean option in any way. In CB2009 you could just press "Backspace" and the override would be removed from the option set. In CB2010 "Backspace" does nothing. In CB2010 you can only set the value to "false" or "true", but you can't change it to 'no change'. It seems there is no way to remove a "boolean" option from an option set in CB2010. QC Entry 77914

The function ReceiveFrom is declared like this: TIpSocket.ReceiveFrom(var buf; bufsize: Integer; ToAddr: TSockAddr; var len: Integer; flags: Integer): Integer; And it calls WinSock.recvfrom to do the work. That is declared like this: function recvfrom(s: TSocket; var Buf; len, flags: Integer; var from: TSockAddr; var fromlen: Integer): Integer; stdcall; If you compare the two signatures, you will see two differences for the third parameter: the name (to instead of from, not a real problem) and that it is not a var parameter in your abstraction (the winsock signature is correct) Without declaring the address as var parameter, the function is not usable, as you will not be able to get the sockaddr from where you got the packet.

In the TSaveDialog.Execute function there is a special handling if the following condition is met: (Win32MajorVersion >= 6) and UseLatestCommonDialogs and (Template = '') and not (Assigned(FOnIncludeItem) or Assigned(FOnClose) or Assigned(FOnShow)) In the case that this condition is met, the TSaveDialog.Handle is not assigned properly (stays zero) and OnTypeChange is fired even when the Dialog is opened. In the case that this condition is not met, the handle is assigned properly and OnTypeChange is only fired when the type is changed. QC Entry 78297

1. place a TSaveDialog component on a form 2. Assign a method to OnTypeChange, that shows a message box showing the handle of the SaveDialog. 3. run the application on Windows Vista and show the Save Dialog ==> SaveDialog.Handle is 0 and the OnTypeChange fires before the Dialog is shown 4. Now also assign OnShow (code does not matter) and repeat Step 3. ==> SaveDialog.Handle is assigned correctly and OnTypeChange is only fired when the type is changed.

QC #: Project Date Reported: Area: 78456 C++Builder 10/8/2009 SOAP\Transfers Description Steps:[QC Short Description] TByteDynArray generate memory leak over SOAP. [QC Description] It's hard to reproduce but I will show the code in OPToSOAPDomConv.pas We want to send a ByteDynArray over SOAP. We have the ByteDynArray incapsulated in an other Class that inherits from TRemotable. When we recieve the ByteDynArray that array is not cleaned up. The reason for that is that the refcount in inc. and when tested if it was Incremented the code is looking at the wrong addres. Here is the code . // get current refcount or set it to zero if Assigned(ArrayPtr) then L := PInteger(PByte(ArrayPtr)-8)^ else L := 0; //Copy dyn array ( inc refcount) SetDynArrayProp(Instance, PropList[I], ArrayPtr); // test if refcount was incremented ( at the wrong address) if (L > 0) and ((PInteger(PChar(ArrayPtr)-8)^) > L) then //decrement the refcount if it was incremented Dec(PInteger(PByte(ArrayPtr)-8)^); in the second "if" the address is calculated with a PChar and with UNICODE wchar_t That is 2 * PByte(x). the result is that "if (L > 0) and ((PInteger(PChar(ArrayPtr)-8)^) > L) then" is looking at the wrong place to check if it should decrement the refcount. As you can see all other places to get the refcount use: (PInteger(PByte(ArrayPtr)-8)^) So we corrected the if to "if (L > 0) and ((PInteger(PByte(ArrayPtr)-8)^) > L) then". The result is now that the refcount is decremented and the array is released from memory. This is where this code can be found. file: TSOAPDomConv.pas

procedure: procedure TSOAPDomConv.InitObjectFromSOAP(Instance: TObject; RootNode, Node: IXMLNode); line: 4403 (my file from 14-01-2009). We have seen in QC that there is a simular problem reported( 21223) in D7 that was solved in D2007. It seems that the fix of that problem(21223) is now causing the Bug. jvdn & jvd. QC Entry 78456

Run it under debugger 3. When program raises exception press Continue 4. Then program crashes because stack I believe overlaps code. Anyway you can compile it with debug dcus and put breakpoint at first line in _ExceptionHandler in system.pas you will see that it calls itself indefinatelly. 5.

Database\TField\TBlobField

Description Steps: [QC Short Description] TBlobField DataSize should return zero [QC Description] A change was made to TBlobField in D2010 that causes the DataSize property to return the size of the blob stream contents rather than zero. This change breaks the previously documented behavior for the DataSize property which requires fields with "data of indeterminate size" to return zero. The new behavior is cleary inconsistent with Delphi documentation and hazardous for code that depends on the previous behavior: http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/delphivclwin32/DB_TField_DataSize.html "The value of DataSize for TField is 0. Most descendants of TField override this property to specify the size required by the specific field type they represent. BLOB fields, however, represent data of indeterminate size. They do not override the inherited method, so the value of DataSize for BLOB fields is 0. A value of zero should not be interpreted as meaning the field value requires no memory. A value of zero indicates that the memory required for the field is indeterminate." QC Entry 78576

Description Steps:[QC Short Description] TBCDField.GetDataSize returns incorrect value [QC Description] A change was made to TBCDField in D2010 that causes the DataSize property to return the wrong value. In previous versions of Delphi, the GetDataSize method of TBCDField returned SizeOf(TBcd). The GetDataSize method has been changed in D2010 to return SizeOf(System.Currency) instead. This change breaks code that depends on the previous behavior, in particular code that manipulates DataSet record buffers. QC Entry 78620

Compare the GetDataSize method implementation for TBCDField in D2010 with that from D2009 and earlier. // DB.pas D2010 function TBCDField.GetDataSize: Integer; begin Result := SizeOf(System.Currency); end; // DB.pas D2009 function TBCDField.GetDataSize: Integer; begin Result := SizeOf(TBcd); end;

Run following program: program Project13; Type TMyClass = Class Public Constructor CreateA(A : Integer); End; TMyClass2<T : TMyClass, Constructor> = Class Public Procedure TestMe; End; constructor TMyClass.CreateA(A: Integer); begin end; procedure TMyClass2<T>.TestMe; begin T.CreateA(0); // It will crash here end; Procedure Test; Var C : TMyClass2<TMyClass>; Begin C:= TMyClass2<TMyClass>.Create; C.TestMe; End; begin Test; end. as you will see it will crash with Access Violation on line with comment //It will crash here. After short investigation I found that compiler generates incorrect VMT. Additional note by USc: It does not compile if the name of the constructor is Create instead of CreateA, because then the compiler allows only the use of the parameterless constructor (constructor constraint). It fails with "[DCC Error] Project34.dpr(20): E2029 ')' expected but number found" and this is similar to QC 78104 (RAID 270162).

Compare the units listed in the IndyProtocols DPK file with those available in the RTM source directories. Compiling the Indy DPK files in the IDE is *not* a valid means of checking for missing files since the missing units exist in compiled form and will not result in a compile error without first altering the library path to exclude Indy.

Description Steps:[QC Short Description] if- and for- statements - CB2010 fatal compiler bug [QC Description] This is fatal in CB2010. CB2007 exhibits problem in executing the attached code as well, but it 'only' missed 2 d'tor calls when unwinding. CB2010 calls the wrong d'tor and missed 4 d'tor calls for if-statement while calling the wrong d'tor *twice* for the for-statement! Calling the wrong d'tor (~Helper() ) with a bogus 'this' pointer is fatal in any non-trivial apps, let alone doing it twice in case of the for-statement. In CB2007 some classes may get by just fine, but with CB2010 caling the *wrong* d'tor with an invalid 'this' pointer (it can't be valid anyway since there's no corresponding c'tor called for this d'tor) will most likely crash an app. Not to mention also that it missed 4 d'tors instead of just 2 (which is already bad enough).

Description Steps:[QC Short Description] Keyboard layout swtching when exiting dbgrid control [QC Description] Added by Sysop <<<<<<<<<<<<<<<<<< Reproducing is really easy; You should have at least 2 input locales installed to be able to duplicate. -> Create a new VCL forms application -> Put a Button, and then a DBGrid on the form, with this order. -> Double click the form and put the below code on the OnCreate event; SysLocale.FarEast := True; (this step might be unnecessary depending on your system input locale) -> Run the project -> Press Alt+Shift to change your input locale to anything other than the default one (or any other means if you've changed the default shortcut keys)

Hi everybody, I recently upgraded from DELPHI 5 to RAD Studio 2010 PRO. I receive very annoying problem: When I have dbgrid control in my form, when dbgrid lose focus, keyboard layout turns to "default". My programs are used in Bulgaria, where normaly default layout is English and alternative (but mostly used!) is Bulgarian, it present annoyng problem. In older version i haven't such problem. If someone has solution to this problem, please post it here or send me message at: office at promsoft dot bg Best regards Georgi

-> Click the DBGrid -> Click the Button expected: The input locale does not default to the default one. actual: The input locale defaults to the default locale. >>>>>>>>>>>>>>>>>> QC Entry 79485

Problem occures during Reconcile process (I have checked this by calling Providers method ApplyUpdates and then Reconcilling result in CDS). When I have changed 3 of InternalCalc fields into Calculated fields everything is ok and error not occures. In another similar situation AV error occures after second CDS.ApplyUpdates(0) (after first is OK - normal update error in onReconcileError occures).

QC #: Project Date Reported: Area: 80204 C++Builder 12/9/2009 Compiler\C++ Description Steps:[QC Short Description] heap memory corruption [QC Description] I am trying to port an application from C++ Builder 2009 to 2010. I attach a skeleton program to reproduce the issue: basically, all it does is load the contents of the "famiglie.csv" file into an array of structures, and then displays this data into a Memo. On 2009, this code runs perfectly and no codeguard issues are reported. On 2010 (I am using the trial version), the first data record is correctly loaded into the corresponding structure, but gets mangled shortly after within rtl40.@System@Move$qqrpxvpvi Thanks for your help. Added by Sysop <<<<<<<<<<<<<< This issue is similar to QC#78772. Please see comments of QC for more information. >>>>>>>>>>>>>> QC Entry 80204

-Open the attached project1 in C++ Builder 2010 -Set a breakpoint at line 72 of Unit1.cpp and start the program -When the breakpoint hits, set a data breakpoint at the address of ef->desc.Data[0] with length = 4 -Continue running the program, the second breakpoint will hit and the call stack will show that the contents of that structure are being overwritten by the rtl40.@System@Move$qqrpxvpvi function. Resuming the execution results in a couple other breakpoint hits, then the messagebox indicating that the first structure is being corrupted appears (sometimes under the IDE window) and finally the Form1 displays only a couple of mixed strings (inconsistent with the data from the "famiglie.csv" file) in the Memo.

During resize a dock zone is constrained so it doesn't overlap more than one adjoining dock zone. The code that looks at the adjoining dock zone fails to take the zones visibility into account. In TDockTree.GetNextLimit: if AZone.FNextSibling <> nil then LimitResult := AZone.FNextSibling.ZoneLimit should be: if AZone.NextVisible <> nil then LimitResult := AZone.NextVisible.ZoneLimit QC Entry 80313

The problem can be reproduced with the Delphi IDE. Starting with the Default Layout: 1) Undock the Project Manager pane and dock it under the Structure pane, above the Object Inspector pane. You should now have three panes docked vertically, like this: [Structure] [Project Manager] [Object Inspector] 2) Close the [Project Manager] pane. 3) Try to resize the Structure pane vertically. It is constrained by the, now hidden, Project Manager dock zone. Exp: The height of the Structure pane can be made smaller or taller. Act: The height of the Structure pane can only be made smaller.

QC #: Project Date Reported: Area:80600 Delphi 12/22/2009 IDE\Dialogs\Project Options Description Steps:[QC Short Description] Version Info in DLL is inconsistent [QC Description] The Project options page has an option to include versioninfo in a DLL. These do not work if a library suffix is included. Is this by design (if so why?) or an error ? QC Entry 80600

To Reproduce. 1. Start a new DLL project 2. Click Projects|Options, select the VersionInfo node and check the "Include vesrion information in project". Click OK to close the dialog. 3. Compile the dll 4. Browse to the dll and check the properties, version info should be included 5. Reopen the project options dialog, select the Application node and enter a string in the "LIB_Suffix" field e.g. "_lib" 6. Switch back to the VersionInfo node. Notice the checkbox is greyed out BUT you can still enter/change info in the fields underneath. Change the version number. 7. Recompile the dll. 8. Browse to the dll (which will now have a "_lib.dll" ending) and check the properties, version info is included but has not been updated. Another sequence of steps to follow is similar to above but adding the library suffix first (clicking OK to save the change) and the try to add VersionInfo. The "Include vesrion information in project" checkbox is now greyed out and cannot be selected.

QC #: Project Date Reported: Area:81256 Delphi 1/18/2010 VCL\System Controls\TTimer Description Steps:[QC Short Description] Changing TTimer.Enabled from thread does not work anymore since Update 4 for Delphi 2010 [QC Description] Added by Sysop <<<<<<< This issue is due to side effect of Internal Tracking Number #201805>>>>>>> Prior to update 4/5 of Delphi 2010, you used to be able the change the Enabled property of a TTimer from different threads. This was possible because the window handle for the timer was eagerly created during the TTimer constructor. Since update 4, changing the Enabled property from a different thread doesn't work anymore. Probably, because the window handled is recreated when you do this. We write software that is highly multi-threaded and we also use different timers on occasion. Some of those timers don't behave correctly anymore now, without warning. This means that current software may behave differently with compiled with the latest Delphi 2010 update. I agree that window handles should not be wasted. But there should be a way do enable/disable timers from different threads. Or at least raise an exception if you try to disable a timer from a different thread than the one that created it. At least that way, we will get notified of any issues we need to change. Granted, enabling/disabling timers from different threads may not be best practice, but it used to work without any problems. QC Entry 81256

1. Create a TTimer, enable it, and wire some OnTimer code to check if the timer fires. 2. From another thread, set the Enabled property of the timer to False. Result: the OnTimer event keeps firing anyway, or worse, the message queue starts misbehaving resulting in an Access Violation.

QC #: Project Date Reported: Area: 81333 Delphi 1/20/2010 Database\DataSnap Description Steps:[QC Short Description] DataSnap 2010 filter performance problem [QC Description] There is a serious problem with the DataSnap 2010 filter performance. When using filters, even do-nothing pass-through filters, the performance can drop by a factor 5-100 (yes, that's up to 100 times as slow as the same request without a filter). The performance gets a little better if you increase the buffer size (at client and server) to a maximum of 1000 KB, but when using an ISAPI DLL, the max buffer size that can be used is 48 KB. As example I've used the ZLibCompression filter, but you can also use a do-nothing filter with the same results. I've created a small demo DataSnap application consisting of four applications. 1. DataSnapServer.exe - A DataSnap 2010 VCL Forms server with a main form where you can enable / disable the use of the Compression filter, and set the BufferKBSize (to a choice of 32, 48, 64, 128, 256 or 1000). Communication protocols are both TCP/IP and HTTP. 2. DataSnapISAPIServer.dll - A DataSnap ISAPI Server with no filters 3. DataSnapISAPIServerFilters.dll - A DataSnap ISAPI Server that uses the Compression Filter 4. DataSnapClient.exe - a DataSnap 2010 client application that can connect to the DataSnap VCL Forms server using TCP (port 211) or HTTP (port 8042), or to either of the DataSnap ISAPI servers. You can also set the Data Size (by default 1024 KB, but you can go from a minimum of 1 KB to any size you want), plus you can configure the

Create DataSnap 2010 Server, use any filter and connect a DataSnap 2010 client to it. Compare the response time to a server with the use of a filter. See the attached project for a ready-to-use example of three DataSnap servers and a client.

BufferSize (same choices as the VCL Forms server - for the ISAPI DLLs you should stick to 48 KB as maximum, otherwise you'll get an error from the ISAPI server). Feel free to test the client and the server. When they both reside on the same machine, there is no performance problem. However, as soon as the client is moved to another (similar!!) machine, the performance problem will show itself. When the Compression Filter is enabled at the VCL Forms DataSnap server, or the ISAPI Server with Filters is used, then the response times increases with a factor 5-100. The trouble is that both the client and server machine appear to be doing "nothing". The CPU load remains low, and the application itself doesn't come above 5% CPU usage, so it cannot be a problem with the processing or filter itself. Especially if you consider that using the filteron the same machine (client and server on same machine) shows no performance loss. The network usage is also very low, so it's not "waiting for data" either, although I suspect that the underlying problem is somewhere connected to an Indy client waiting for filter data to come in? (remember that it also fails for an ISAPI DataSnap server). I've spent almost a week trying to figure out where the bottle-neck is, and I just give up and have to report it here. Hope someone can shine a light on this, as this problem renders the use of filters almost impossible unless you stick to very small data packages (but even then the performance hit is noticable, and relatively worse of all). Delphi 2010, Update 4+5 applied. Using Windows XP, 2003 and 7, but the same problem bas been reproduced by others using Delphi 2010 as well. QC Entry 81333

TryCast calls IsEmpty, which returns true under the following circumstances: if (FData.FTypeInfo = nil) or (FData.FHeapData = nil) then Exit(True); case FData.FTypeInfo^.Kind of tkClass: Result := FData.FAsObject = nil; tkInterface: Result := FData.FHeapData = nil; tkMethod: Result := FData.FAsMethod.Code = nil; else Result := False; end; Aside from the redundant check for FData.FHeapData = nil, there's a problem with the code. When the return value gets used, back in TryCast, it checks this line: Result := (ATypeInfo <> nil) and (ATypeInfo^.Kind in [tkInterface, tkClass, tkClassRef]); Therefore, if your TypeInfo kind is tkMethod and the method's Code pointer is nil, this will always fail and raise an exception in TValue.Cast, when it should have succeeded. tkMethod needs to be added to the set in the line above.

relaunching the IDE so there becomes two instances of the IDE.

Description Steps:[QC Short Description] ColorDepth related issues with cdDeviceDependent [QC Description] While upgrading sources code from Delphi 2006 to 2010 I encounteredseveral issues related to the new ColorDepth property and its default value cdDeviceDependent: - runtime transparent drawing using the TImageList's Draw method icw the properties BkColor and BlendColor set to clNone worked fine when first drawing a black background. This now leads to an image with a black background. This can only be fixed by drawing on either a clWhite background or setting ColorDepth to cd32Bit. - Calling Assign on a TImageList object with ColorDepth set to cdDeviceDependent (i.e. not set, just using the default) leads to a "hanging" application (actually TCustomImageList.WriteData hangs in calling ImageListWriteExProc). Question is why a new default value creates so many issues, while setting the ColorDepth to cd32Bit seems to fix all these issues (on Xp, Vista and Windows 7). QC Entry 81502

Just take .dfm (created in Delphi 2006) with a TImageList instance on it and all the properties set to default. Open the corresponding source file in D2010 and leave everything to their defaults. the bugs mentioned in the full description can be reproduced.

Expected 'case', the expression, and the colon to be on one line. This is OK if the expression is a single token, but not if is an expression. The presence of ( ) changes the formatting but neither is correct [vk] it was already fixed for a long time

Description Steps: [QC Short Description] IncMilliSecond goes negative [QC Description] When I use the IncMilliSecond function to "add" 1500 milliseconds to a TDateTime value of 0 (zero) the result is negative. When I use simple arithmatic to do the same thing the answer is, as expected, positive. The problem is that when I compare the TDateTime value the answer is "incorrect" QC Entry 82166 Added by Sysop <<<<<<<<<<< Please see comments of QC for more information. >>>>>>>>>>> [AMP] The bug also

To show this I created a simple application with a button and a memo field on the main form. I put the following code in the buttons OnClick event handler... //============================================================================== procedure TfrmMain.pbGoClick(Sender: TObject); var Dt : TDateTime; begin Dt := 0; Dt := Dt + 1.5 / 86400; mmOutput.Clear; mmOutput.Lines.Add ('With simple arithmatic...'); mmOutput.Lines.Add (FormatDateTime ('dd/mm/yyyy hh:nn:ss.zzz', Dt)); mmOutput.Lines.Add (FloatToStr (Dt)); Dt := 0; Dt := IncMilliSecond (Dt, 1500); mmOutput.Lines.Add ('With IncMilliSecond function...'); mmOutput.Lines.Add (FormatDateTime ('dd/mm/yyyy hh:nn:ss.zzz', Dt)); mmOutput.Lines.Add (FloatToStr (Dt)); end; //==============================================================================The memo field has this in it... With simple arithmatic... 30/12/1899 00:00:01.500 1.73611111111111E-5 With IncMilliSecond function... 30/12/1899 00:00:01.500 -1.73611111111111E-5 You can see that the last value is negative! The documentation for IncMilliSecond states that the input value is "incremented" by the number of milliseconds. I believe that the result of my code should be positive.

reproduces when using IncMinutes or IncHour. Also, RAID 266110 it's the same bug, just on another version( 12 ).

1- Create ActiveX Library 2- Add an Automation object (not sure this is strictly necessary). 3- Add an enumeration. 4- Add a few constants to the enumeration, leave the default names (Const1, Const2, etc.) 5- Save the project 6- Change the name of Const1, say to Const1xxx. Click refresh button. The name of Const1 is NOW changed to Const1xxx. 7- Save project again. 8- Close project. Re-open project. Const1 is not called Const1xxx but the original Const1. (NOTE From Bruneau: Chris correctly identified that this problem is tied to code in the 'Refresh' handler that was no longer flushing the Type Libray model to the .ridl buffer. I've attached an image that shows that the 'Modified' flag is not ON after 'Refresh' - which is a good sign that changes to the typelibrary won't be saved. I've checked in logic to flush the model on 'Refresh'. Let's hope this does the trick).

Description Steps:[QC Short Description] TForm.DoKeyUp not called from controller if docked

Take a form (with KeyPreview set to True) and try out OnKeyDown and OnKeyUp. All works. Then dock the form, now only OnKeyDown works.

[QC Description] TWinControl.DoKeyUp is missing a check to see if the form has a parent (ie: it is docked). This result in that the controller does not send respond to keyup events up to the form if it is docked. TWinControl.DoKeyDown on the other hand does have this check and works good. To Fix it simply compare the very similar TWinControl.DoKeyDown and TWinControl.DoKeyUp and the problem will show itself. QC Entry 82201

The code, in the same method, that inserts an empty menu item via the VK_INSERT key correctly notifies the menu designer with a call to NotifyDesigner(). While you're at it, replace with '-' with cLineCaption - that's what it's there for. QC Entry 82220

QC #: Project Date Reported: Area:82862 Delphi 3/10/2010 VCL\Additional Controls\TBitBtn

Description Steps:[QC Short Description] TBitBtn.NumGlyph behaviour: it seems a bug... [QC Description] In Delphi 2010 I found a strange behavior in setting the property NumGlyph of a TBitBtn: I put a TImagleList 16 x 48 with a 3 state bitmap 16 x 48 (normal, disabled and focused) and I link it to an ActionManager (I can see all bitmaps correctly). Then I link the Action to a TBitBtn and I see 3 bitmaps, so I set the property NumGlyph to the button and at Design Time I can see only 1 bitmap (correctly). If I run the program I see 3 bitmaps erroneously! With Delphi 2007 all is fine. It seem a bug because when you set a non standard value to a property in D2010 you?l see it in bold, setting the property NumGlyph to the value 3 does not change font style.. Besides all works fine if I set the property at runtime. QC Entry 82862

Start new project Add a Image list Set the property width to 48 Add a 16x48 bitmap into the image list Put an action manager or a action list in the form Link the action manager to the image list Create a new action and connect to the only one image (that has 3 states) Put a TBitbutton and link it to the action created ...You'll see 3 images Set the property NumGlyph of the button to 3 ...You'll see only 1 image (correct) Run the program: you'll see 3 bitmaps! (error) See attachement as a test project. Thanks, Thomas. Note: With the test project, I see 3 images both at runtime and design time.

Write an app that calls SHDoDragDrop or SHCreateDataObject.

QC #: Project Date Reported: Area: 83466 Delphi 3/30/2010 RTL\Delphi\WinAPI Description Steps:[QC Short Description] HDROP is incorrectly declared in ShellAPI.pas [QC Description] HDROP is declared in ShellAPI.pas as: type HDROP = Longint; This is a signed integer. It is used in calls to DragQueryFile, DragQueryFinish and DragQueryPoint. The problem is that it is in fact a Windows handle and as such should be declared as an unsigned integer because this is the convention that Delphi has adopted (e.g. declaration of THandle). Now, most of the time this doesn't matter but it will if the HDROP value has its high order bit set. This typically happens in a 32 bit app running as LARGEADDRESSAWARE. And in order to make the problem manifest it is commonly neeeded to run with top-down memory allocation. When the high order bit is set there is a range error when calling any of the DragQueryXXXX functions because the value passed in as the HDROP parameter is typically the result of a call to IDataObject.GetData and is typed as HGlobal. I can work around this problem by using an explicit cast which bypassess type coercion but it really ought to be fixed in future releases. The fix is trivial: type HDROP = THandle; QC Entry 83466

However, your compiler appears to have a similar problem with regard to built-in arrays. The C++ Standard (2003) says that to value-initialize an array means that each element is value-initialized ([dcl.init]). However, when I try to value-initialize an array, the compiler gives me a warning instead: "W8039 Constructor initializer list ignored". And when I do so for an array of integers, they remain uninitialized. (Or at least, they remain non-zero.)

Despite the claim that it makes code easier to read, the automatic code formatter can make thousands of lines of neatly formatted code unreadable in an instant. Control-D key is dangerously close to the often used Control-F, Control-X and Control-C keys, and gets pressed accidentally.

QC #: Project Date Reported: Area: 84520 Delphi 5/11/2010 Debugger Description Steps:[QC Short Description] Debugger visualizers are very slow! [QC Description] Hi! In order to make use of debugger visualizers, the plugin has to depend upon a function:

Steps by USc: - save the attachment - install DebuggerEvaluationSpeedTestPackage.dpk - open DebuggerEvaluationSpeedTestApp.dpr - put a breakpoint into it and run it (the test needs an active IOTAProcess + IOTAThread and also EncodeDateTime linked into the app) - Help | Debugger Evaluation Speed Test - press the "Test" button and wait till the test is finished (may take up to 30 seconds) and have a look at the result expected: the evaluation with ProcessDebugEvents is at least as fast as with

IOTADebuggerServices.ProcessDebugEvents when evaluating deffered expressions. This approach results in very slow debug step times when using value replacement visualizer and when there are many locals declared in the functions. They will make use of the debugger value replacement plug-in automatically to populate the "locals" debugger window. A part from the fact the function is between 6-10x slower than the approach using Application.ProcessMessages, it effectively prevents widespread use of debugger visualizer features because it can easily bring the debugging process to its knees in terms of stepping speed. The function would have to be speeded up about 50-100x times to allow for widespread adoption of the new debugger features. (or a completely new approach to debugger expression evaluation should be made available). Thanks! Atmapuri QC Entry 84520

ProcessMessages (>= 33 evaluations per second on an 2.1 GHz Core2) actually it should be also faster than the current speed with ProcessMessages to avoid slowing down stepping too much actual: ProcessDebugEvents is 6.6 times slower than ProcessMessages (5 evaluations per second on an 2.1 GHz Core2)

But didn't mention localization resources. EDIT 2010-05-13 Ok, here's the call stack... Kernel32.RaiseException DatabaseError

Run the attached project with the French localization resources (*.fr files)

DatabaseErrorFmt TDataset.FieldByName TFilterExpr.GetFieldByName TFilterExpr.NewNode TExprParser.ParseExpr7 TExprParser.ParseExpr6 [...] TExprParser.ParseExpr2 TExprParser.ParseExpr TExprParser.SetExprParams TExprParser.Create TCustomClientDataset.LocateRecord [...] I noted that in TExprParser.ParseExpr7, the TokenSymbolIs(FStrTrue/FStrFalse) both return FALSE. Those 2 fields are initialized with constant from DBConsts and both seems to be localized. Which means that TExprParser expect boolean strings to be "Vrai/Faux" with the french resource. In TCustomClientDataset.LocateRecord, the boolean values contained in the KeyValues parameter are converted like this: ValStr := VarToStr(Value); which maps ultimately to _VarToUStr. and then to BoolToWStrViaOS. I tested the BoolToWStrViaOS, and it returns "True/False" even if the language of my OS is french and the *.fr resource are loaded. So the problem I encountered is: The TCustomClientDataset.LocateRecord function use the "True/False" string to format the filter expression, but the TExprParser only consider "Vrai/Faux" to be valid boolean strings. Note : GetThreadLocale, GetUserDefaultLCID and GetSystemDefaultLCID all return the same value ($0C0C) QC Entry 84541

QC #: Project Date Reported: Area: 84913 Delphi 5/26/2010 Database\DataSnap\Server Description Steps:[QC Short Description] IAppServer not exposed when Invocation Lifecycle is used [QC Description] D2009 exposed IAppServer methods when the server class's Lifecycle was set to Invocation. D2010 does not. Whether the class needs to expose IAppServer methods is determined

DataSnapDM.Native.Db.Test.exe connection=mssqlconnection server=dstcp_win32 -s:TestRaid_278935 -OR- Create a new DataSnap server in D2010. On the TDSServerClass component, set LifeCycle to Invocation. On the TDSServerModule, drop a data set and a TDataSetProvider component. Setup the data set

and this value is saved to "IsAdapted". If IsAdapted is True, then the server class is wrapped with TDSProviderDataModuleAdapter, which exposes the IAppServer methods. D2009 determined IsAdapted using this logic: D2009: DSServer.pas: function TDSServerClass.GetDSClass: TDSClass; Line 563: IsAdapted := PersistentClass.InheritsFrom(TProviderDataModule); D2010 adds a check to determine if Lifecycle is set to Invocation: D2010: DSServer.pas: function TDSServerClass.GetDSClass: TDSClass; Line 571: IsAdapted := PersistentClass.InheritsFrom(TProviderDataModule) and (LifeCycle <> TDSLifeCycle.Invocation); I've researched this and I can't find any reason that IAppServer methods will not work with Invocation Lifecycle. An instance created is not freed immediately after the AS_GetRecords call is completed. However, this because DataSnap has code that determines the instance is not ready to be freed yet. When the next server call is made, it is determined that the previous instance still exists, so that instance is freed and another instance is created. The net result is that each server call results in a new instance of the server class and that a single connection only has one instance of the server class at any given time. There are two side effects that may be undesirable: 1. The server class instance is not freed when the programmer expects.2. Once a connection makes a server call, there is always a service class allocated, even though it will be freed with the next server call. However, the solution to these two side effects is not to disable the IAppServer methods when Invocation Lifecycle is used. Please restore the ability to use IAppServer (and thus TDataSetProvider) when Invocation Lifecycle is used.

QC #: Project Date Reported: Area: 85671 Delphi 6/24/2010 RTL Description Steps:[QC Short Description] CommCtrl.InitCommonControlsEx fails when comctl32.dll has not been loaded into the application. [QC Description] CommCtrl.InitCommonControlsEx uses GetModuleHandle internally. GetModuleHandle, however, will fail to return the requested handle if the module has not been loaded into the application before it's called: Thus this won't work: program Project1; uses Windows, CommCtrl, XPMan; var Ctl: tagINITCOMMONCONTROLSEX;

Create a new console application Replace the entire code section with this: Program Project1; uses Windows, CommCtrl, XPMan; var Ctl: tagINITCOMMONCONTROLSEX; begin Ctl.dwSize := SizeOf(tagINITCOMMONCONTROLSEX); Ctl.dwICC := ICC_STANDARD_CLASSES; InitCommonControlsEx(Ctl); MessageBoxW(0, 'Text', 'Caption', 0); end. Notice that the message box is not shown.

begin Ctl.dwSize := SizeOf(tagINITCOMMONCONTROLSEX); Ctl.dwICC := ICC_STANDARD_CLASSES; InitCommonControlsEx(Ctl); MessageBoxW(0, 'Text', 'Caption', 0); end. because comctl32.dll simply hasn't been loaded: This do work: program Project1; uses Windows, CommCtrl, XPMan; var Ctl: tagINITCOMMONCONTROLSEX; begin Ctl.dwSize := SizeOf(tagINITCOMMONCONTROLSEX); Ctl.dwICC := ICC_STANDARD_CLASSES; ImageList_GetImageCount(0); InitCommonControlsEx(Ctl); MessageBoxW(0, 'Text', 'Caption', 0); end. because ImageList_GetImageCount makes sure that comctl32.dll is loaded before the call to GetModuleHandle. The result is that controls with visual styles failes to be painted. QC Entry 85671

QC #: Project Date Reported: Area: 85763 Delphi 6/28/2010 Debugger Description Steps:[QC Short Description] Debugger should evaluate sets of enumerated types to a fully-expanded list by default [QC Description] I have a type that's a set of a certain enumerated type. When viewed in the debugger, it collapses contiguous subranges into "start..end" style. That makes sense if you have a numeric set. It's pretty helpful in that case. But when your elements are name and not numbers, it becomes confusing quickly, since you can't easily look at it and determine whether a given element is in the set or not. When displaying sets based on enums, the debugger should always evaluate to a comma-separated list, and not collapse subranges. Apparently the functionality for this exists in Evaluate/Modify if you add ",e" at the end. This view style should be the default for all sets of enumerated types, not only in Evaluate/Modify but also in tooltips, in the Local Variables view, in Inspect windows and in watches. (And anywhere else I may have neglected to mention.) QC Entry 85763

QC #: Project Date Reported: Area: 85764 Delphi 6/28/2010 Debugger Description Steps:[QC Short Description] Invoking Evaluate/Modify should always copy text from the code view, if applicable, even if the window is currently visible [QC Description] When I position the cursor on a piece of code and hit Ctrl-F7, it brings up Evaluate/Modify with the current expression filled in. If I highlight code and hit Ctrl-F7, it fills in the entire highlighted section. That's good. But if I then click into or highlight some other code and hit Ctrl-F7 again, without closing Evaluate/Modify, it focuses the Evaluate/Modify window but it doesn't replace the current expression with the new one I selected. That's annoying and ought to be fixed. QC Entry 85764


QC #: Project Date Reported: Area: 85765 Delphi 6/28/2010 Debugger Description Steps:[QC Short Description] Evaluate/Modify can only copy 80 characters from the code view [QC Description] Evaluate/Modify seems to only be able to copy up to 80 characters if I highlight a selection, and then truncates it if what I highlighted was longer than 80 characters, leaving me with an error message and the task of manually copy/pasting the rest of it into the Expression box. The Expression box is perfectly capable of holding more than 80 characters, and the evaluator is capable of evaluating more than 80 characters, so why the limit on how much it will automatically copy? This is annoying, and ought to be fixed. QC Entry 85765

QC #: Project Date Reported: Area:85844 Delphi 7/1/2010 VCL\Docking Description Steps: [QC Short Description] DockManager.LoadFromStream causes app to hang [QC Description] When a stream previously generated with DockManager.SaveToStream contains values that LoadFromStream is not anticipating, DockManager.LoadFromStream gets stuck in an infinite 'while' loop, and the entire application hangs.

You may need Controls.pas in front of you to follow along... {code} // read dock zone tree (line 14397 in Controls.pas) while True do begin with Stream do begin Read(Level, SizeOf(Level)); if Level = TreeStreamEndFlag then Break; .... ReadComponentName(CompName); //Line 14414 .... end; .... LastLevel := Level; LastZone := Zone; end; //Line 14460 {code} Example of a 53 byte stream that causes a hang: {code} 0000080000010000000017D0200000000000001EB00000000000000010000000017D020000080000007067635351554F51FFFFFFFF {code} Example segment from the above stream: {code} "...00080000007067635351554F51FFFFFFFF" {code} Using the above Stream segment as an example, while reading the Stream, the 'while True...' loop calls ReadComponentName. This immediately reads an integer $0800 (2048) from the Stream and then attempts to read 2048 bytes from the Stream. However the Stream is only 53 bytes long, so it just reads to the end of the Stream. Note that ReadComponentName has just read past the TreeStreamEndFlag markers in the Stream (-1 / FFFF), so from this point onwards a TreeStreamEndFlag can never be found. Control returns to the 'while True...' loop, which doesn't know the Stream has ended. It continues trying to read from the Stream (receiving zero bytes each time) looking for a TreeStreamEndFlag which will now never occur. No check is made to see if the Stream has ended, so the 'while True...' loop continues looping forever and the app hangs. Something obviously went wrong while reading the Stream: The Stream originally generated by DockManager.SaveToStream is likely corrupt/inappropriate in some way; but the immediate problem seems to

This also occurs when a stream passed to DockManager.LoadFromStream ends unexpectedly (truncated stream). Explanation: The '// read dock zone tree... while True...' loop (Controls.pas line 14397) contains no error checking, and never tests to see if the stream has ended. When a stream ends prematurely, either because it is a truncated stream, or because ReadComponentName has attempted to read beyond the end of the stream, the only exit condition (if Level = TreeStreamEndFlag then Break;) can never be met, and the routine then loops forever trying to read bytes from a stream that has already ended. QC Entry 85844

be that LoadFromStream has no error checking or end of Stream checks. This means that any Stream containing unexpected values or that is truncated will cause the entire app to hang, instead of throwing an exception for the app to handle.

If you want a more precise kind (eg TComponenTHash), it's easiest to descend from THash and copy the TObjecTHash code. Note that TObjecTHash is slightly different from TIntegerHash and TStringHashbecause it has to free items -- it cannot just overwrite them. Internal data representation: Each hash object has an array (potentially dynamically sized, but thisisn't used yet) of 'buckets' (dynamic arrays). Each bucket is mapped to a series of hash values (we take the high order bits of the value calculated), so that every possible hash value refers to exactly one bucket. This reduces the amount of searching that has to be done to find an item, so it's much faster than linear or B-Tree storage.

begin SetLength(FKeys[0], 0); end; end.

Each bucket contains a series of integers. These are indexes into an items array, which for type reasons is maintained by the descendant classes.

QC #: Project Date Reported: Area:85893 Delphi 7/2/2010 VCL\Registry / INI Objects Description Steps: [QC Short Description] TCustomIniFile.InternalReadSections does not return exactly matching section name [QC Description] Since D2010 TIniFile and TMemIniFile defer to TCustomIniFile.InternalReadSections to do their ReadSections work.

When the Section parameter exactly matches a section in the ini file, the InternalReadSections method does not add it to the Strings.

The CodeGuard reports a error saying that two different CRTDLLs are loaded (name of the DLL-Project) (c:\windows\system32\cc32100mt.dll) This behavior is new in C++ Builder 2010. Older version worked fine. We need a solution on that, since we strongly relay on CodeGuard for Code Quality reasons.


QC #: Project Date Reported: Area: 86364 C++Builder 7/17/2010 VCL\Graphics Description Steps:[QC Short Description] Unresolved External SetPrinter [QC Description] I am using RAD Studio 2010 with all the latest updates applied to it (v 14.0.3593.25826) and am having trouble with the following method: function SetPrinter(NewPrinter: TPrinter): TPrinter; When I try and use this function I get an unresolved external linker error. QC Entry 86364

This can be simulated by starting a new project and putting in the following code: TPrinter *new_printer = new TPrinter(); TPrinter *old_printer = SetPrinter(new_printer); When I try and build this I get: [ILINK32 Error] Error: Unresolved external '__fastcall Printers::SetPrinterA(Printers::TPrinter *)'

[QC Short Description] Missing #pragma alias statements in several headers [QC Description] Many of the RTL/VCL header files use #pragma alias statements when _VCL_ALIAS_RECORDS is defined to re-map function/method names that were incorrectly altered by #define statements in Win32 API headers. However, several RTL/VCL headers, such as StrUtils.hpp, are missing aliases. A code review of all RTL/VCL header files needs to be done so missing aliases can be inserted where needed. QC Entry 86394

The following snippet should illustrate both the problem and the fix: // ----- // DB.pas, l. 4265ff procedure TField.AssignValue(const Value: TVarRec); ... begin with Value do case VType of ... vtPChar:

In this case, it may modify the reference count of what it thinks is an UnicodeString, but it in fact it corrupts memory because the string is actually a WideString


QC #: Project Date Reported: Area: 86768 Delphi 7/30/2010 VCL\Graphics Description Steps:[QC Short Description] TIcon does not support loading 256x256 icons correctly [QC Description] TIcon does not correctly support 256x256 icons. The width and height fields in the ICO header are 0, since they are stored as single bytes and thus cannot contain values of 256. When loading a 256x256 icon using TIcon.LoadFrom...(), the resulting TIcon.Width and TIcon.Height properties are 0, not 256. On some systems, this incompatibility in TIcon is causing EOutOfResource exceptions to be raised, such as when assigning such as TIcon to a TBitmap. If Graphics.ReadIcon() is tweaked to assume width/height=256 when it encounters width/height=0 in the ICO header, then everything works ok. QC Entry 86768

var Icon : TIcon; Bitmap : TBitmap; begin Icon := TIcon.Create; try Bitmap := TBitmap.Create; try Icon.LoadFromFile('c:\temp\bigicon.ico'); // <- use a 256x256 icon file, see attached Bitmap.Width := Icon.Width; // <-- will be 0, somes raises EOutOfResources Bitmap.Height := Icon.Height; // <-- will be 0 Bitmap.Canvas.Draw(0, 0, Icon ) ; Bitmap.SaveToFile('c:\temp\bigicon.bmp') ; finally Bitmap.Free; end; finally Icon.Free; end; end;
