Dennis-
Well, in the After Update event of "A", if it's not a hotel-related item, set
combo B to Null and set Locked = True. You'll also probably need code in the
Current event of the form to unlock combo B unless the row already contains a
non-hotel event.

Subject: Re: [MS_AccessPros] How to let contents of one combo box affect
contents of another combo box
Thanks John,
I am not quite sure what level of detail I should give you, but I will try:
The combo boxes are actually part of a subform for order details. The outer
order form is used to register basically hotel bookings, and the combo box B in
my mail is used to present the available alternatives of hotel names, and the
combo box A presents a list of available types of rooms, like double room,
single room, extra bed, etc.
However, there are also other "product types", that may be ordered on an order
detail line like e.g. dinner, sightseeing tickets, program catalog, etc. And for
those types there is no connection to a specific hotel name. So for those cases
I want the program to fill in a default value indicating there is no hotel
involved. And thus making it possible for the keying user to just skip that box
and continue to the remaining relevant boxes on the order detail line. The data
source behind the combo box B is simply a table containing all available hotel
names and a number as primary key.
Well that was trial to give some more details.
Hope you have got the picture now roughly.
regards
Dennis
