Research focusing on the WM_KEYUP or WM_KEYDOWN windows message 
(WH_KEYBOARD hook).  I would suggest that you lean toward the keyup 
becaue if the user holds the key, Windows will REPEAT the keystroke.

Best advice I can give is that you purchase the book titled "Subclassing 
and Hooking with Visual Basic" (O'Reilly, Teilhet) which has a LOT of 
detail around this OR if you have access to Desaware SpyHook, it is much 
easier to do what you suggest (at a cost) OR use Google or MSDN and 
search for code samples using the constants I mentioned in first 
paragraph.
