If I corectly remember, to write a hook code you have to place it in dll and then call those functions from your program. Search msdn for these things.
msdn.microsoft.com

Why not just look for the WM_CHAR event, or WM_KEYBOARD (or whatever) event and then stop processing that message when you are done with it.

Otherwise you will have to hook with a DLL file. Look it up on msdn, or thecodeproject.com.
