school VFP, is the first to see the tables in the database field can be defined rules and record-level rules, It was used? I think very few. Why? Because under normal circumstances, as defined in the rules, is a database engine from the errors, and it is very beautiful. VFP form with the Wizard do form, a good solution to the problem. How has it been resolved? I do not know whether it was the right heart, I do anyway. N years later, I finally understand how it used to. You? Still not understand? Download and watch it. Perhaps, you can change many of VFP awareness. From my station : http://www.chinavfp.com
