Frank,

I think I have every VFP book that has been published and the best introduction to OOP that I have found (with a VFP focus) is:

Object Orientation in Visual Foxpro
by Savannah Brentnall
ISBN 0-201-47943-5

The book is a very easy read and you don't have to be sitting in front of your machine to get through it. Here's a quote:

"Savannah uses great analogies and real-world examples toclarify the terminology, benefits, and pitfalls in making the transition from procedural programming to OOP....If you trat FoxPro as a religion (as I do), then Object Orientation in Visual Foxpro will become your bible"

-From the Forword by Ken Levy
