Hi!
First hide the button created by Delphi for the Application:
ShowWindow(Application.Handle, SW_HIDE);
SetWindowLong(Application.Handle, GWL_EXSTYLE,
GetWindowLong(Application.Handle, GWL_EXSTYLE) or
WS_EX_TOOLWINDOW and not WS_EX_APPWINDOW);
ShowWindow(Application.Handle, SW_SHOW);-- Vladimir Yushko http://yarrowsoft.com/ ---
