Access Database Locked to Multiple Users, How Do I Unlock it?

Hi Experts,

I have a database that needs to be open to multiple users. Currently when it is opened by one user it creates a  Lock File. The main window is a form that allows record searching via the record selector arrows, and auto update entry fields.

How do I allow multiple users? Do I need to eliminate the record selector arrows, or put in a save button?

Your best bet in allowing multiple users is to split the database into a frontend (code/forms/reports etc) and backend (data only)
the frontend then consists of tables that are linked to the backend

You place the backend on a network folder somewhere and give each user a copy of the frontend.
Using this approach as opposed to sharing one db also gives u less chance of corruption

have a look at tools/database splitter

Firstly, the database should be split as a front-end and a back-end. Put all your tables in one database (the data) and queries, forms, reports, etc. in the front-end. "Link" to all the tables in the back-end. Make a copy of the front-end for each user. This process works quite well with Access in a multi-user environment. Also I avoid bound forms and, yes, I would eliminate the record selectors. Let the users select the record they want to work with by using a combo or list box.

I have seen all in one databases that allow multiple users. How is this accomplished/ why is this different?

in tools/options/advanced there is the option to open the db as shared or exclusive. But I strongly recommend u dont go this approach. This approach is more prone to corruption.

The Advanced option is set as Shared already

There is no event on open.

Are u saying u want one user to have edit permissions, but others to have read only?

what u can do is put db on a network and set folder permissions to read/write for all
this way the lock file can be created
however the database file itself should only have write permissions to the one user, and be read only for all other users

All users must have write permissions, these can be done through single record update Save routines. Its a customer issues database so CSRs will have it open all day and log customer issues.

The DB is on a network drive.

You cannot prevent a lock file from being created - the ldb is created even if a single user opens a database

Im not the only one that recommends splitting databases in a multi user environment, there are plenty of other sites out there that also do.
If u do go this approach, u may be interested in this

Don't forget security on that folder must enable the user to write/modify.
