AddObjects that appear in the definition of the class (header) are part of the class themsleves. As such when VFP creates the internal interface table or typelib, they are included. For an example, use the class browser to export a composite class to code. You will see all the contained objects as AddObject lines.

As for using your own classes, that is easy. As long as the class library is set to use your class, the AddObject will find it. As an aside, I don't know if it works in class definitions (it probably does) but you could use the NewObject syntax and specify a class library if the class library is not already set.

>Yes you right, but what if the new added object is a not a base class of vfp instead some other class.
