Not true. See my response to Terry. You can now create an entire BizObject (at runtime) complete with a private DataSession, DataEnvironment, Cursors, Relations, etc. without using a form object.

>I never said that you can't use your own class, only that if you want to add a dataenvironment to a container, that container has to be a form. Many frameworks use custim DE classes- this is a great way to do things- but the DE's are still being added to the forms- only at run time instead of design time.

>Jeff- yes there is a new session class that shipped with SP3. This is not a containerclass however, and cannot hold cursor objects. It was primarily to make working with Multithreaded DLLs simpler- so you could have a single class without the overhead of a form class, that had it's own private datasession.
