Check if any debugging symbols weren’t in binary. Also possible is using GDB (on Windows a port of it). It would be great if you found a .dbg or .dSYM file. They contain source code, eg. gdb> list foo 56 void foo() 57 { 58 bar(); 59 sighandler_t fnc = signal(SIGHUP, SIG_IGN); 60 raise(SIGHUP); 61 … Read more
In the System.pas (which automatically gets used) the following is defined: const sLineBreak = {$IFDEF LINUX} AnsiChar(#10) {$ENDIF} {$IFDEF MSWINDOWS} AnsiString(#13#10) {$ENDIF}; This is from Delphi 2009 (notice the use of AnsiChar and AnsiString). (Line wrap added by me.) So if you want to make your TLabel wrap, make sure AutoSize is set to true, … Read more
Your settings in the .dfm file will be scaled up correctly, so long as Scaled is True. If you are setting dimensions in code then you need to scale them by Screen.PixelsPerInch divided by Form.PixelsPerInch. Use MulDiv to do this. function TMyForm.ScaleDimension(const X: Integer): Integer; begin Result := MulDiv(X, Screen.PixelsPerInch, PixelsPerInch); end; This is what … Read more
Yes, this is the documented behaviour: Object fields are always initialized to 0, 0.0, ”, False, nil or whatever applies. Global variables are always initialized to 0 etc as well; Local reference-counted* variables are always initialized to nil or ”; Local non reference-counted* variables are uninitialized so you have to assign a value before you … Read more

One possible way is to use the Visual Studio tool Spy++. Give this a try: Run the tool (for me, it’s at C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Tools\spyxx_amd64.exe or you can download it). Note: there is spyxx.exe (32-bit version) and spyxx_amd64.exe (64-bit version) – if you don’t see anything in 64-bit use the 32-bit version (ie.catches … Read more
It is just the result of a long day and we had gotten a little giddy. For many, many years (ever since I’d been on the team), we’d always joked about replacing some error message in the compiler for one of the most common errors with a similar message. Internally we’ve always joked and poked … Read more
It is possible using NSPanel with NSNonactivatingPanelMask flag. The NSView of fmx form should become child of NSPanel. I have written a helper class which works for both Windows and Mac platforms (Works on XE4): unit NoActivateForm; interface uses Fmx.Forms, Fmx.Types {$IFDEF POSIX} , Macapi.AppKit {$ENDIF} ; type TNoActivateForm = class private form: TForm; {$IFDEF … Read more
I have posted the complete set of demos for SOAP on CodeCentral as item 28789. These contain every single one of the Delphi 2007 era SOAP demos from the WebServices folder, now updated for Delphi XE and XE2, including converting the old WAD servers into new INDY VCL servers. You’d think that was impressive, except … Read more
Normally we get the 0xC000007B error-code (which means STATUS_INVALID_IMAGE_FORMAT), if: If a 32-bit app tried to load a 64-bit DLL. Or if a 64-bit app tried to load a 32-bit DLL. Or if a 64-bit app tried to run on a 32-bit Windows. To really know, I would suggest to test whether there is a … Read more
