Disabling Alt+F4

Question

I'm doing a fullscreen game and I want to prevent the user from being able to close the form using the alt+f4 shortcut. How would I do this?

I would create a hidden menu and a menu item underneath it that has as its shortcut AltF4. Create an empty handler function and you're done. If you really want to get into the nitty gritty or don't use a windows form you can override WndProc. protected override void WndProc(ref Message m) { if(m.Msg==... && m.wParam==...) { } else base.WndProc(ref m); } You'll be able to find the constants in windows.h somewhere.
