>I have a class library with a combobox that I've customized by adding additional properties and methods. Now I want to use it as a starting point for another combobox class. Can I duplicate it without having to manually rebuild the entire thing as a new class? I thought that the Class Browser might do it but I don't see anything there.
Mike,

The whole idea of classes it that you can use the existing cxlass as a starting point for a new subclass by simply creating a new class that is a subclass of your existing class. You don't copy and paste code to the new class, you make the new class a subclass of the existing one and it magically gets all of the code and properties of the existing class.
