Thanks for the reply, Jacques,
In case anyone wants to know the solution to this problem, the replies I got
boiled down to: coding the dialog itself so that it calls a handler
procedure, then use this handler to set the selected items in the multi list
box.
Once again, thanks to everyone for the help.
