A bit more information:
Environment is win32.
The line that raises the exception is in win32callback.inc 2474:
-------------------------------------------
if (Msg=WM_CHAR) and (WParam=VK_RETURN) and
((lWinControl is TCustomCombobox) or
((lWinControl is TCustomEdit) and not (lWinControl is TCustomMemo ))
)
then
// this thing will beep, don't call defaultWindowProc
else
PLMsg^.Result := CallDefaultWindowProc(Window, Msg, WParam, LParam);
-------------------------------------------
The CallDefaultWindowProc.
If I change the line to:
try
PLMsg^.Result := CallDefaultWindowProc(Window, Msg, WParam, LParam);
finally
end;
The problem dissapears.
* In the same function, if I declare an ansistring type, just the
declare only, it works.
* If the "CallDefaultWindowProc" declaration is changed to stdcall it
also works fine.
