>Anyone as a suggestion on a good book on OOP? (related to VFP or not)
Yes... and related to VFP. Pinnacle Publishinga serious of "Special Report" books on VFP and the first one is called "Object-Oriented Programming with Visual FoxPro" by David Frankenbach and edited by Whil Hentsen. I ordered this series from the Pinnacle Publishing website
www.pinpub.com and found them all very useful. (sorry for the late response but I've been on a long vacation :))
