Bonnie,

This is not a solution to your immediate problem, but a strategy to
follow in the future.  Have two environments; the current production
environment your users are in, and a development environment for your
use.

Both environments should start with exact copies of the production
application.  You do your work in the development environment without
having to worry about any users trying to update data while you are
making your changes.  When you have made all the current changes and
have thoroughly tested them, then you promote your version of the
front-end to the production environment.  Usually this promotion will
only take a few minutes and can be done at the beginning or end of the
work day without disrupting the users.

If you have to promote a new version of the back-end, then there is a
little inconvenience for either you or the users since you will have to
make sure no users are in the production back-end while you are copying
and converting the data to the new back-end.  Depending on how big a
change you have made to the BE this could be minutes to hours, so you
may be forced to do it during non-business hours.

I just got an e-mail from a site I frequent that they will be down for
maintenance this weekend and to expect to see some changes when they are
back up Saturday night or Sunday morning.  So they are following this
strategy.

I am the only one that does any programming edits, and I'm careful not
to do it during the two weeks when we are doing the data entry.  The
only way anyone else gets into the database is through the data access
pages.  The  database was created in Access 2000 (9.0.6926 SP-3).  I'm
not sure where to look for the system release of Jet.  I found some code
to let me see who was in the database so I could call and ask them if
they had completed their data entry so someone else could get in, and we
were able to get things done, but it was not a satisfactory solution. 
We will be needing to do data entry again in September, so I'd like to
find a solution before then.  :-)

It could be a lot of  things. What level of Office was this developed 
on. What service pack and System Release of Jet, but could it be that 
someone is opening the mdb or adp to perform programming edits and this

has to be done in exclusive mode or someone could be just opening the 
mdb by clicking on the file directly to do data edits. There is an 
option from Tools menu to force either shared or exclusive opening but

this can overridden. I can give you some code to force a shared open and

if some tries an exclusive open indicates machine and user name.
