VB.Net 2005, Access 2000
I have a VB.Net App that uses an Access Database. There are a handful of users for this application. I need them to all be able to view the data from the database (via datagridview), but only one user at a time should be allowed to modify data in the database. There is not a login for this app, so I would like to set it up so the first user in would have modify rights. How can I accomplish this?
