How much experience do you have with ActiveX Controls? I'd be happy to
unload that part. I can then work on the results grid with hand-entered
queries until the control is done. Once the control is done (at least
alpha), we could work on the query design grid, and getting the
relationships, query grid, and SQL pane to work together. But we really
need the relationship control first, at least enough to see what will and
I can send you what I have so far, but probably not until tomorrow night, as
I have quite a few other things that need to be done.

Mark, you seem to be well on the way! Is there anywhere you think I could
Dave/Jean is there any way you can set up a sep portion on the CVS where
this semi project can be held, without necessarily giving us rights to
upload the main project files for pgAdmin????
