[AccessD] Building a control class

"oops!" when one of them doesn't apply?

It's worse than that though.  If you intend to sink events in your class then you MUST dimension the 
control variable WithEvents, and you cannot do that for a generic control object.  Try it and you 
get an immediate compile error stating that "object does not source automation events".

IOW you must:

Dimension WithEvents ctl as combo
Dimension WithEvents ctl as textbox
Dimension WithEvents ctl as tab

Dimension WithEvents ctl as Control is illegal syntax and throws an error as soon as you hit compile.
