Hmm, I got it going in 5 minutes in VC6. Works quite well.

Well, I can certainly commit what's there fairly quickly.

That's a good point. Magnus, any thoughts on doing it that way?
Shouldn't be too hard to swap out the queries for scans of the tree.

Mind you, the downside of that is that tab complete would essentially
have to build large chunks of the tree on databases that might not even
be connected in response to random typing in the query tool. Whilst it
seems a nice idea to use the tree objects as a cache, it could have some
pretty nasty side effects.
