>I keep hearing about VFP8's ability to subclass native data environment and cursor classes. To me, this is nothing new. I already have an app in production that uses custom subclasses of native cursor and data environment objects. Using these objects, I was able to build a generic data access framework for working with SQL Server via SP's. How are the new implementations different from the existing?

In VFP 8.0, you can subclass the DataEnvironment via the VCX visual classes. You can create a subclass in a VCX from a SCX DataEnvironmment, you can sublcass the DE class visually using the Class Designer / Class Browser, you can apply any DE class (PRG or VCX) to any Form class in the VCX system or PRG based form, and there is a complete DataEnvironment Builder or use with DataEnvironment classes that also allow you to use the new CursorAdapter class to save writing code in many cases.
