ok, I stand corrected.
I know it was writeable in VB5 forms and vividly recall trying to use it in
a similar fashion with Access forms and running headlong into the
"read-only" limitation, so I found an alternative solution for whatever it
was I was trying to do and have treated it as read-only ever since. I just
assumed that it was one of the few differences in how VB forms and Access
forms/controls implemented certain things. This memory goes back to A97
however (maybe it was read-only then??), so I'm making a mental note to
revisit the issue next time it comes up.
