Couldn't update; database is read-only.
You tried to save changes in a database that was opened for read-only access.
The database is read-only for one of these reasons:
You used the OpenDatabase function and opened the database for read-only access.
You are using the Data Control, and you set the ReadOnly property to True..
The database file has been defined as read-only in the operating system or by your network.
In a network environment, you don't have write privileges for the database file.
Close the database, resolve the read-only condition, and then reopen the file for read/write access.
