Ed,
Thank you for your response.
I am looking at the ItemProvider Jet template but I have no experience
working with them. What do I need to do/learn so that I can modify them to
accomplish what I need? Can you please give me some hints? I'd rather
spend few hours learn how to do this instead of spending the hours
commenting out the default generated code.
Which part of the template looks up the subclasses and how can I change it
so that it only adds the declared reference type as a child? (I am
pasting below the part of the template that appears relevant)
Thanks,
Shahim

You've looked at the FAQ? You've uses the nice google newsgroup search
to find previous posts?

Yes, I can imagine...

It's complicated. I could spend quite a bit of time just trying to
explain it and I don't have that much time.
