Christof,

Much Thanks for your clarification. Bob's original message now
makes total sense in the context that you have just explained.

Not having yet moved over to VFP6 I did not understand the crucial
issue of the VFP6 foundation classes.

Thanks again.
Michel.

>VFP 6 ships with a set of classes, called the FoxPro Foundation Classes, sort of a minimal framework. These classes have their own subclassed base classes, just like you would do it in your own development. The problems start when you try to use the Foundation Classses together wit your classes. Then you have to base class libraries that are sub classes from the native VFP classes. By redefining the foundation classes to inherit from your base class library, all of the foundation classes behave just like yours.
