After configuring my project for the my business object (BO), setting the table for the BO,. I try to use the listbox control on my main form. My problem is that i can't set the primarybusinessobject property of my form. Am I forgetting something?

I think that my DataLayer.Datasource.Add ("", connectionstring) is wrong. To give you a better feel of my SF application with security, I have a DB different than the one use by SF (containing the table of my BO). Eventhough the help is well written, it doesn't see to explain the procedure to create a perfect BO . The first time I ran the application, the connection wizard was use to specify the SF DB. Is it the way it's supposed to work? Or I was supposed to specify my other DB? I hope I was clear enough ...

A quick answer will be greatly appreciated.

Thanks in advance

As for why the primary BO cannot be set on the form... you have to have a business object dropped on the form.  The drop down list will list all of the business objects that have been dropped on the form.  Configuring the business object is much like creating your own custom control.  Once it's created, it's just added do your project.  You then have to drop it on a form to use it.
