[Lazarus] Lazarus and Windows messages
Hello,
It's the first time that I use Lazarus with Windows, and almost 10 years
since I last developed to Windows.
I'm trying to capture the windows message WM_QUERYENDSESSION (that exists
on JwaWinUser).
I did something like this:
TForm1 = class(TForm)
...
private
procedure WMQueryEndSession(var Msg : TLMessage); message
WM_QUERYENDSESSION
...
end;
...
procedure TForm1.WMQueryEndSession(var Msg : TLMessage);
begin
case Msg.lParam of
ENDSESSION_CLOSEAPP : ShowMessage('Closing Application'); // Added it
by hand <-
http://msdn.microsoft.com/en-us/library/windows/desktop/aa376890%28v=vs.85%29.aspx
ENDSESSION_CRITICAL : ShowMessage('Critical reason');
ENDSESSION_LOGOFF : ShowMessage('Log off');
end;
Msg.Result := 1;
end;
...
It looks like the message never fires.
I'm using Windows 7 64 bit, Lazarus 0.9.30.4 FPC 2.6.0 i386
What am I missing or doing wrong ?
Thanks,
Ido

[Lazarus] savedialog issue
Dear all, I encountered a strange behaviour of TSaveDialog. I have a big project, inside of it many TSaveDialogs. Recently I found that sometimes the dialogs are not shown. I didn't find any explanation on this behaviour, here what I understood: TSaveDialog is shown on execute all the times except when I got exceptions (out of memory exceptions that are managed using try finally or try except). I tried to go inside the execute, since when I call execute it gives me back False without showing the dialog. In function TCommonDialog.DoExecute : boolean; FUserChoice is assigned 2 (mrCancel). I don't know why. I would like to know where/what I have to check in order to understand this behaviour. Anyone can help? Any suggestion? I use: Lazarus 0.9.31 r37846M FPC 2.6.0 i386-win32-win32/win64 Best regards, Andrea Mauri -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Héctor F. Fiandor Rosario Héctor, Please don't try to start a new thread by replying to another thread. It now appears as if you're responding to the "IDE problems when using record helper types" thread. It would help if you said which tutorials you used and what parts you didn't understand/where it went wrong Actually, perhaps this might be better suited for a forum conversation as you can easily add screenshots etc, but perhaps that's just me. I don't know all the tricks of using Lazarus, but I did extend the SQLDB Tutorial1 on the wiki a bit. I've been interested in adding some notes to make it more useful for sqlite; perhaps now is the time to do that based on e.g. your feedback of what wasn't understandable.

Re: [Lazarus] IDE more ...
Right. Same symptoms. Antonio. Le 01/07/2012 19:00, Bernd a écrit : 2012/7/1 Mattias Gaertner : For instance, I dock the project inspector, the objects inspector and the call stack all together. When I reload Lazarus I only get the project inspector and I have to manually dock again the other two windows. Fortunately, the code main editor, the top main form (editor tool buttons and components) and the messages window are always kept in place. Please create a bug report so this is not forgotten. I plan to work again on docking next month. There is a bug report already that describes these symptoms: http://bugs.freepascal.org/view.php?id=19714 -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
