Subclasses can provide much more functionality than a class extension.
If your design requires the control to have extra properties or
events, then a subclass is a must.
If you are only adding extra methods to a framework object (e.g.
adding another method to the listbox) then use an extends method (I
have a whole Extension Library Module which extends the built in
framework to suit my needs), it's much cleaner and doesn't require
you to subclass all of your controls.

Are there any advantages or disadvantages to using class extensions

having a slew of classes hanging around.
