从Word中提取方程和图像

Is there a programmatic way to extract equations (and possibly images) from an MS Word document? I've googled all over, but have yet to find anything that I can sink my teeth into and work from. If possible, I'd like to be able to do this with VB.NET or C#, but I can pick up enough of any language to hack out a DLL. Thanks!Is there a programmatic way to extract equation
