Bob,
I stand corrected. Thanks for your feedback.

>Now... it CAN be done... I have done it... of course... Terry and others... I do agree with Dior and others that if you want to create a Business Component to market, make it without a UI... let whoever buys the component from you create the UI... You just provide the business service in your .DLL that it is you are selling.
