How to

One way of Locking Records in a Multi-User Scenario by Ogart
Posted: 12 May 03

Situation: You know there will be multiple users, and your application has some data entry forms. You don't want users to overwrite a record that someone else is editing.

Resolution: You want to set the Application to pessimistic Locking. This means that once a user looks at a record, it's locked up and only that user can make changes.

How To:
1.  Stick this in your module.  
     Public Sub SetRecLocks()
     'This command sets "Pessismistic" locking.
     'If someone is poking around in a given record, no one else can edit it.
     Application.SetOption "Default Record Locking", 2
     End Sub

2. Presuming you've got a form that always opens at startup, stick this event driven piece in it
     Private Sub Form_Load()
     SetRecLocks
     End Sub
