Really? But I suppose that would depend both on the building tool (does it publish it in the tlb?) and the IDL viewer (is it trained to ignore IObjectControl?). I can't see how IObjectControl could in any way be inherently 'invisible', since IDL and the various parsers are obviously much older than COM+ and IObjectControl.

Incidentally, I am having trouble getting the IMPLEMENTS keyword to work- Classes defined with it compile fine, and the methods show up in the tlb, but neither OLEView nor the VB or VFP object browsers show the implemented interface listed. Any idea what I could be doing wrong? Does it work for you?
