CM_DIALOGKEY message

[Tan Chin Leong]

Hi there,

I saw several examples on handling TAB Key press.

Example:

Procedure CMDialogKey(var Message: TCMDialogKey);message CM_DIALOGKEY;

Procedure TForm1.CMDialogKey(var Message: TCMDialogKey);
begin
if CharCode = VK_TAB then begin
{Process the Alt+Tab key here}
Message.result := 1;
exit;
end;
inherited;
end;

May I know what do Message.result := 1 actually do ? Why 1 and NOT 0, 2 or
other number ?

Please help :)

It tells Delphi that the message has been handled. If you set Result
to 0, Delphi will continue to try to find some other handler for the
message event.

Good luck.
