Your own Ctrl+Alt+Del?

It's called a system wide keyboard hook ( http://www.google.com/search?source=ig&hl=en&q=system+wide+keyboard+hook&btnG=Google+Search). For simplicity, any VB can easily handle it. I am sure that Any C-based language could as well.

I am using C++ and I found the API SetWindowsHookEx() to do the job for me. But I don't really understand how it works. MSDN says that for a system-wide hook, the callback procedure that processes the keyboard input must be placed into a DLL. A program then loads the DLL using LoadLibrary(), gets the address of the callback using GetProcAddress() then passes the address to SetWindowsHookEx() to install the hook. But when the program exits - does it not have to call FreeLibrary() on the DLL which means it will no longer be in memory and the hook will no longer be in place? Does that mean that this program that calls SetWindowsHookEx() needs to be running throughout the time I want the hook to be in place?

Thank you, HanneSThEGreaT, for that excellent advice. I finally did, using RegisterHotKey(), in a matter of minutes, something I was struggling to do with SetWindowsHookEx() for days.
