Subject: control definition functions without CDEFs?

I'm writing up a bit of source which, eventually, I'd like to distribute.  It
uses custom CDEFs, but one thing I'd like to do is to avoid making users
of the source copy extra CDEFs into their applications--that is, I'd like
to build the custom controls entirely within the source.  The first
problem I've run across (there may be others) is the fact the contrlDefProc
field in a control must be set to a HANDLE to the control definition
procedure--so how do I get a handle to the procedure I'm using, which
is defined in my source?  Second, IM mentions that "You should never
have to access this field directly" (an obvious lie :-) ), so if I insist
on doing things like this, is the system going to burn me?

Any other suggestions in this admittedly unusual endeavour would be
most gratefully received.

Thanks,
Ken McDonald
