Problem updating record in Access 2007 database from Excel Worksheet

I have a macro in my excel workbook that updates a specific record in the access database related to the spreadsheet.

All works fine if the access database is closed. Problems arise if the database is open and a user is editing the specific record that the excel spreadsheet relates to.` I get the following Error Message:

Error Number 2147467259: 
The database has been paced in a state by user 'ADMIN' on
'LAPTOP' that prevents it from being opened or locked.

I have set the database form's Record Locks to 'No Record Locks' but this hasn't helped.

Any advice or help is greatly appreciated.

Cheers Noel

It seems that you have not split the database into a front-end and a back-end. The problem goes away if you do. Ctrl+S is not for saving a record, that is Shift+Enter, it is for saving a database object, and so it seems it has the effect of throwing the database into design or development state.

On the macro side; have you tried opening your connection as read-only? Even though your Access user is not locking the record, he has a "read lock" on the record, thereby preventing an exclusive lock by excel. I'm thinking that if both users are only attempting only read access, you should be Ok; but if either one is doing read/write, then it will fail.

On your access form, you should also have:

Me.AllowAdditions = True

Me.AllowDeletions = False

Me.AllowEdits = False

The problem is probably not in your code. The error:

The database has been paced in a state by

Indicates that the database has been opened in an exclusive mode. You should check how you are opening the database.
