How to Subtract one Polygon from Another

I have two polygon geometries - one is a polygon from a feature and the other is created from the current view extent (which is always the larger polygon, if that matters). I want to subtract the feature polygon from the view extent polygon, creating a polygon with a donut hole in it. Is there a simple way to do this?

I'm using VB.net.

Thanks for any advice.
