Question

How do I trap Windows key, Alt+Tab, and Ctrl+Alt+Delete in a Windows application using C#?

Answer 1

Some Remote Management Software and Virtual Machines do this. If you press [CTRL]+[ALT]+[DEL] the specific Windows Dialog will still opens, but the Application also displays, that you have pressed [CTRL]+[ALT]+[DEL] and probably wanted it t become effective on the Target Machine and not your host. It seams rather easy to capture these keys, but cancelling the Event may be harder.
