Ok Im creating a game in full screen 3d mode... I want the game to END if the user trys to switch to another app using alt+tab or what not. So how do I detect when the app is suspended or losses focus????

you can either use api_HasFocus() -> if in focus = true or api_IsIconic(hwnd) -> if minimized = true (both commands come with user32.decls) cheers, chi

Why would you want the game to end if the user switched screens?

You do realize that lots of processes can cause your game to lose focus? I mean, things like virus checkers and instant messengers, those can momentarily steal the focus.

I'm developing a VERY strictly enforced RPG. I want to prevent the use of other apps such as messengers so players can't use them to "unnaturally" cooridate attacks or otherwise be distracted from the RP.
