Exactly. But, this might not require too much of a rewrite -- just remember, as long as you can fill in the information (properties), call the right code (sub), and get the right info back (return value or property), you will be okay. Depending on the complexity, it may be as simple as moving the existing lookup code into a VB class module, and binding their lookup form controls to public properties (which you could also fill in from outside the COM component). Remember, it doesn't have to be perfect to be useable -- this approach isn't really so complicated.

Good luck.
