Hi List,

does anyone know how to change the application title on the windows xp taskbar? Specifically, while my application is crunching data, I would like to minimize it and then display the percentage of the calculations on the taskbar.
At the end, the application should restore itself and be brought to front.

Thanks a lot,

Roberto

Application.Title := 'New title'?

If you want the MainForm title and the Taskbar button title the same, that should work. In windows you can actually have different titles for each of those. I've done it before, but I can't remember off the top of my head what Win32 API that was.

Obviously, I am writing to the list just because that does not work. Any change to Application.Title in the form unit or in the .lpr main program after Application.Run is not propagated to the taskbar.

Any hint?

This works on windows (form with on button):
procedure TForm1.Button1Click(Sender: TObject);
begin
   Application.Title:='New Name';
end;

Maybe you don't give windows time to make that change, because you are processing. (one long event handler without processing message)

Graeme, if you could find the piece of code, you'd do me a favour! Or maybe someone can point me to some piece of information online... As far as I can see, any change to Application.Title after the Application.Run in the main program is not propagated to the task bar name nor to the form caption, which has to be changed through its property

Thanks!

Right, I tried it in one of the buttons I have and it works: it changes the taskbar title, but not the form caption (which I can change through the property).
But I cannot see it work during the calculations, even if I call the Application.ProcessMessages that was already there to update a progress bar.
However, it must be an update problem, because the ShowMessage dialogs that appear between the steps of the calculations are use the correct Application.Title.

The taskbar is update much less frequently than the other graphics; does anyone know if I can send a message to windows to have it refreshed every once in a while ?

Thanks,
