Can you not test for the proper "exposure conditions" in the object's .Init() event and simply return .F. if a given object should not be instantiated ?

The Forms .Load() could do some preliminaries if need be. Other than that, the Form then does not have to be aware of which (specific) Controls need to be subsequently destroyed.
