I created several controls in VB that I want to use in my custom container.
The container does special things with these specific controls and allows
the user to pick which one to load by using a drop down box.  This box is
filled with the ProgIDs of the controls that support a new class category
that I created.  I found no way to have my VB control register the fact that
they implement the class category during the regsvr32 registration process.
At this point I have to run a .REG file to add the implemented category
information.

How can I build my VB control so that it registers the fact that it
implements a class category of my choosing?

Thanks
