Question : Access ADP / SQL 2008 locking records

I have an access adp database which is linked to sql 2008

I have 2 different lists on 2 different forms which read the same data. I have the attatched code on the double click event of this list.

The code all works fine however on the code attatched and a similar code on another form, when the person tries to move to another record they get the message box about another user editing data. Normally they can click save and it will work, however sometimes they can keep clicking save a dozen times and nothing will happen.

is there a way to stop this from happening? I asked around the building about some of the records and other people said they were not in it at the same time only earlier on in the day.

Answer : Access ADP / SQL 2008 locking records

My recommendation would be to use a SQL stored procedure. Collect and verify all input data, then execute your stored procedure. In the stored procedure use a transaction to make sure all the updates are executed in one swoop. Your code does not guarantee that another user is updating the data concurrently...
