Low Level Keyboard Hook

This program performs a low-level hook for the keyboard using the Windows API, and provides programmatic interaction with these keys. You can either allow or prevent keys to be processed. This application prevents Alt-Tab, Alt-Esc, Ctrl-Esc, and the Windows key. Ctrl-Alt-Del is still enabled. This is very similar to the "Disable Low Level Keys" provided by MSDN, originally in VC++ 6. This has only been tested on XP Pro.
