Thank you very much for your answer!

>I have my framework mostly in one classlib ccontrol.vcx that has cForm, cTextBox etc., each client gets a classlib that subclasses only the base control classes to bForm, bTextBox etc. These "b" classes are the ones used to build the application. Only very rarely does code get put in the "b" classes when the client wants some different behavior. But the "b" layer does allow easy whole scale visual changes at the client level.

>At one point in the design I added an "a" layer derived from "b" to provide individual application subclasses, but that was over complicated and harder to maintain. I also decided if a client wants multiple apps they should always have the same look and feel to reduce their training costs. So I abandoned the "a" layer.

>>We are using Visual FoxPro 5.0 and we have build a framework. Of course we want to make other applications from the framework. Now we would like to know if it is better to copy all the framework-classes to the new application or that we will use the classes from the framework directory. In the last case it will be possible that if we change a method in de framework-class, all applications will be changed. We would would like your opinion please.
