I am writing a program in VB express 2008 which I want to be able to receive input from an xbox controller as well as activate the rumble on the controller. I am using the XBCD drivers for the controller (http://www.redcl0ud.com/xbcd.html).

Basically I want to say "the further forward the thumbstick is pushed the more the controller should vibrate".

How do I go about this?

Thanks
Chris
