Dontcha just love that we have tabs on navigation controls on navigation forms and tabs on tab controls, which by the way, are not really tabs but pages?? We could be talking about either here. Wish I had a dollar for every time the problem turned out to be the other. I think the first line of post 2 is a good way of knowing what's what and I'll keep it in mind for future reference. Here's where you can find virtually anything you want to know about objects and their events, methods and properties. Of course, it helps to know what you're looking for, but as long as you know you're dealing with a tab control, you can drill down to pages and discover they're not called tabs at all in code.
