ACCESS FEED: RE: [MS_AccessPros] Re: Populating an unbound textbox with multi item field

Walter-

The problem is a Combo Box acts in a "special" way only when it is bound to a
multi-value field. When bound to a normal field or unbound, it's just a plain
Combo Box. To do what you want, you would have to use a plain text box and use
your code to assign the list of comma-separated values to show the underlying
multi-values. I'm not sure how you would handle letting the user update the
values to add or remove a Station.

John;
It's in the file root directory (my bad) named "TrainDB" it's a zip
and has only one form and all the objects to make it work.
I don't have all the update/add record stuff working yet, wanted to see if I
could get past this multiselect thing
