As I said only public variable in VFP is oApp and rest wishfully avoided by VFP itself:) If you need it just have it as a property of oApp.
I can't turn a textbox to an editbox or combobox etc. They are different classes. If I do that by also changing the class, it's simple to change them vs a form case because it is likely a textbox or any other object is referenced in code for 0 or few times. Just a single replace all would do.
