Ok, I see. You can add a new method to your object SwitchDS. This method will save current DS and set DS to passed DS. In form's destroy you will call RestoreDS() method of this object.

How about this idea?

>The thing is that I wasn't _instansiating_ the object from the form at all. I was just calling it from there. It's a global object. That's what the problem was. But making it a local object makes it useless, so my only option is to give up on trying this n-tier thingy and going back to just talking to the data directly.

When the object's code runs, it errors because it can't find the cursor I told it to put the data in (which was created in the form). If I suspend, I can see that I'm in the default data session, and not the form's private data session. I need the object to use the same datasession as the form that is calling it, _not_ the default datasession. How do I do that?
