Hi Susan

You can't hack controls that are included with the form (as a composite class). That would be like performing magic on a heart patient's heart to make it inherit from a pig or some other animal.

Hacking can alter the inheritance structure of an object. So, if the form you are looking at inherits from frmDEGridNav2Pages, you could hack it to make it inherit from frmXXDEGridNav2Pages.

If you added a txtBase to a form and later decided it should have been a txtPicklistValid, you could hack that txtBase and change it to a txtPicklistValid.

If we go back to the heart analogy, you can add a pacemaker and magically change the type of pacemaker, but the heart came with the patient and you can't change it easily.
