>If I am right when I learn about enhancement in VFP 7 that we can trigger some code before a valid for example. The syntax was something like _before_valid. And also do some code after with something like _after_valid. But I can't remember exactly how to write the code and I can't find in help file some reference about that. Maybe someone know what I am talking about
