Hide a form's taskbar button without using WS_EX_TOOLWIN

Question

I need to hide a Windows form from the taskbar but I can\'t use WS_EX_TOOLWINDOW because I need the system menu and min/max buttons on the form\'s title bar.

With thanks to http://www.scalabium.com/faq/dct0096.htm.

procedure TForm1.FormCreate(Sender: TObject);
begin
  ShowWindow(Application.Handle, SW_HIDE);
  SetWindowLong(Application.Handle, GWL_EXSTYLE,
    GetWindowLong(Application.Handle, GWL_EXSTYLE) or WS_EX_TOOLWINDOW);
  ShowWindow(Application.Handle, SW_SHOW);
end;

I tested it and it worked with Delphi2006. And windows menu and min/max buttons are still visible.
