I have my app and want to make it run in full-screen mode, no task-bar. I found out how to hide the windows bar but when I start my app it doesn\'t cover the space of the windo
After hiding the task bar, explicitly set the size and position of your Form:
myForm.Width = Screen.PrimaryScreen.Bounds.Width;
myForm.Height = Screen.PrimaryScreen.Bounds.Height;
myForm.Left = 0;
myForm.Top = 0;
I've always used SHFullScreen to achieve this when required. You will need to use PInvoke to call it.
