Hi, Steve. Elsewhere in this thread I said to "ignore my other post," so I'm
thinking that my post here got ignored, when I actually meant the other one.
Thus, I'm reposting it below, in case that happened. Thanks!
Neil
Original post:
That sounds fine, and is similar to what I mentioned (working set key would
be machine name). When you used these, were they linked to an MDB or were
they just back end processes? I need to be able to use this in a bound form
approach, where the selection check box on the form is bound to the
selection table. Thus, the recordsource for the form needs to just return
the records pertaining to a particular working set key. How did you
accomplish that?
Thanks,
Neil
