Hide an application from the taskbar

This is a really simple technique that can hide your application from the taskbar.

In your main forms On Create event, type the following code:

   SetWindowLong(Application.Handle, GWL_EXSTYLE,
                 GetWindowLong(Application.Handle, GWL_EXSTYLE )
                 or WS_EX_TOOLWINDOW and not WS_EX_APPWINDOW);

That's all there is to it.
