Thanks again everybody:

The spec calls for a listbox with entries for all of the
organization's contacts, probably in the neighborhood of 10,000, but
it could be quite a bit bigger.

I'm just selecting the columns needed to fill the display, and the
contact's key.

But this is part of the specifications.

This is an infrequent operation, and will only be performed once
for each time the user wants to load the records.

As I've said so many times in the past, I appreciate everybody's
assistance.

Thanks
Larry
