Yep, exactly. I'm currently struggling with Puzzle 4. It should be something simple, like derivation, but I could not yet make it. I started a thread in VFP Russian club. May be it's already in the Non-trivial tasks section, I'll check.

>>>This is just a sample. To make it generic, you have to add checking for ActiveX controls, OLEBoundControl (you cannot compare field of General type) etc. I also did not tested the code - it was just a sample I took from my head. I used this approach many times to assure active control saved its value before firing the Valid event of the control.

>>>>Here is a problem: for convenience in Data Entry I have certain F keys to perform actions. For instance, F9 key saves the data. First it checks validity of the data and if everything is fine, saves it. Otherwise it brings focus to the offending field. So, I type something in the textbox, then press F9 and it gives me the same error again, because field source hasn't yet updated with the value. What can I do? In FormValid always check against form controls and not the actual fields? Is there more convenient method?
