What you can do:

Define your own classes as you need and want them.

After that, open your actual vcx files as dbfs (USE command) and modify them "by hand". I think there are 2 fields you must modify. I don't remember exactly the names of those fields. There is a very good article in the March issue of FoxPro Advisor on it. It's no big deal to modify the parent class for a class in a VCX. You must modify the name of the parent class and the source vcx file for this parent class.

The same goes for form files (scx).

>>You can't. Subclass them and add your properties and methods. Why do you need to add mandatory to base classes?
