Question
Trapping keyboard input?
I'd like to know if it;s possible to have a program run in the background that traps keyboard strokes. So I can run the program and while I work in say a chat window or something the keystrokes will be recorded in a text file.

You surely can, but it's not so easy. You need to create a sustem keyboard hook. This hook is a procedure which will be executed every time a key is stroked under Windows. The worst part is that this procedure (called hook procedure) must be in a DLL. If you want to record a keystrokes of a given window or textbox, there is surely an easier way.
Two ways to do it: subclassing or hooks
