If you suddenly can't get any database actions to work it might be because it has something to do with case sensitivity.

I decided to do a number of changes to my project, which is pretty hefty, including prettying up the names so they look better.

I happened to change purhead, the name of my Purchasing application's header business object, to PurHead.

After that none of my database actions, New, Update, etc. would work any more or I should say nothing appeared in my controls. I thought that Basic was case insensitive, so didn't even think of that as a problem, also since I made name changes in my code from purhead to PurHead, and we all know that source code is case insensitive. It took a week for me to find that the problem was each control's BindingSource.

When I picked each control's (38 of them on one tab page alone) BindingSource from purhead to the new name, PurHead, it all worked again.

Bugger.
