Hi, Dmitry,

>>In the Class Browser, right click on a class and Select Parent Class will allow you to follow the class heirarchy back.

You may also check Steven Black's Share.prg (http://www.stevenblack.com/files/share.prg) which extracts classes out of a given VCX preserving their integrity. This is a great help when you just want a given class out of an overloaded VCX.

Hope this helps,
