Q
I did figure out the meaning soon after and, as you saw, MSDN was not much help. However, the MSDN example is part of a larger example which only implements Select. So, they carved it up, exceptions and all, into the individual examples... I'm in the middle of a project to write a "generalized" solution for managing table data with no special fields. Beware of assignments to "generalize" something, as managers will not allocate enough time to complete them, no matter what.
