>I agree that the VFP books were very good. But then again, that was the time when I/we was/were learning the stuff that we were using every day. Now, the new stuff, is mostly to "complement" our work. And I tend to forget what little I learned, and go in circles.

But, all the core aspect of everything from those books and conferences you might have attended remain, no matter the technological environment you would move into.
