Mike,
Usually instead of copying the class to a new place and modifying it, you subclass it. Subclassing container the classes with other objects inside them can be problematic though.
To get your subclasses used in forms will involve opening the forms as tables and modifying the classloc and class fields. You can do this with a .prg that can easily handle all your forms.
>I am working with VFP 3.0, and built a form using the form wizard. Now that I understand a little bit more about how to use classes and class libraries, I would like to make some changes in in the wizstyle.vcx base class to make my form work better. However, I would rather not alter the original wizstyle classes. Is there a way for me to make a copy of this class library in a different location, and re-associate the form's base classes to this new class library?
