[Request] Spambot (Universal?) with hotkeys

I wish to learn how to program my own spam bot that spams 2-3 different messages with working hotkeys. (Start, stop)
If possible, could you show me how to code it so I can change the speed and what not?


EDIT: I wish to use this on Combat Arms, so would I need a bypass for it?

RE-EDIT: I don't know what section this goes in so I posted it here. Sorry if this is the wrong place.

Take a look at the following APIs in MSDN Library :
keybd_event
GetAsyncKeyState

You probably don't need a bypass to call these APIs, unless of coarse GG hooks them. In which case you can find some lower-level APIs that it doesn't hook or rehook'em.
