Shortcuts for disabling hardware

Hi,

I got a laptop with built-in wireless-B card and just bought a wireless-G card. In most cases when I am on the road I will use the built-in card because it doesn’t stick out on the side, i.e. I won’t break it when I take the laptop out of the bag.

Is there a way (maybe using a .BAT file or .REG file or some simple Visual Basic procedure) that I can create a shortcut on the Desktop that will disable or enable one or the other of the two cards?

I would prefer to do this on the fly without restarting.

Any thoughts?

Thanks!
