Jose,

Let's use an example to show this. You have a combobox class with code in the .When and .Valid events. You subclass your combobox and want *different* logic in the .When and *additional* logic in the .Valid:

.When

{your new code}
NODEFAULT

.Valid

{your additional code}
DODEFAULT()

The one thing to remember with DODEFAULT() is that if the method/event has a parameter, include it like so DODEFAULT(parameter). HTH
