Hi Kevin,

In your method inside your Form_B_Logic class, make sure you are receiving the actual Form B class and not just Form. If you define the receiving parameter to be of type "Form" then you only see the properties and methods of the Form class.

The logic in this class would need to 'see' and read the contents of the controls in Form B. And that's where I get stuck...if I pass the form object as a parameter from Form 'B' to the Form B Logic class, the class doesn't see any of the controls on Form 'B'.

That way, the form itself has nothing more than the controls and function calls to the form class logic. It's one of these cases where I knew how to do this in VFP, but haven't figured out how to implement in .NET.
