>Markus Egger's "Advanced Object Oriented Programming with Visual FoxPro 6.0" (www.hentzenwerke.com) The title is misleading. It is very readable for anyone with a modest understanding of VFP and deals with concepts that are important to understand for anyone wanting to use the tool.

PMFJI. I am going to second this. I thought it was going to a difficult read, but Markcus has a great writing style.
