>12 - But if you press the F8 key - Will appear just 1 message... The ThisForm.TextBox.Valid is not execute.

THats correct. That is because when you hit F8, you call the code YOU assiociated with Save.Valid(), you don't actually create the event of teh TextBox.Valid() and the Focus doesn't actually move().

Does that make sense? Just because you call an event, you really only call a method with your code that is assicioated with that event.
