fullscreen

I am creating a kiosk application and I want to ensure it is always, no matter what, on top of other Windows applications and the Windows task bar.

I am already blocking Windows keyboard commands (alt-tab, etc) but there are still situations that could cause an application to launch and steal the screen.

Is it possible to hook into Windows from .NET and continually test whether the application has focus and is on top, and if not then give it focus and make it on top?
