I too have some forms with complex rules like yours. When I do, I create a new method for just that form and put all my code there. Some might say the code should go in each control's refresh, but labels do not have a refresh, plus it is easier to maintain all the rules for the controls on the form in just one place. Of course, I know rules never change and enhancements are never asked for.
