>Do you normally create a subclass of one of the default classes? I was thinking of like a collection class object.

Always. In fact usually to 2 levels!

We have subclassed all the base classes into a company base class vcx, then for all but the most trivial applications we then create another sublibrary for the application itself, whose parents are all in the company base class.

ie. fh_base.vcx is our framework level subclassing and then for example we wrote an application called "Eden" and the first thing we did was create Eden_base.vcx which inherited all the base classes from fh_base.
