If your app is not the foreground app, SetForegroundWindow will flash the
taskbar icon.

On a new project, drop a TTimer, paste this, run, and minimize your app.


procedure TForm1.Timer1Timer(Sender: TObject);
begin
  SetForegroundWindow(Form1.Handle);
end;


see msdn:

"An application cannot force a window to the foreground while the user is
working with another window. Instead, Windows flashes the taskbar button of
the window to notify the user."
