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 method and opened the database for read-only access.

  • In Microsoft Visual Basic, you are using the Data control, and you set the ReadOnly property to True.

  • The database file is defined as read-only in the operating system or by your network.

  • The database file is stored on read-only media.

  • In a network environment, you do not have write privileges for the database file.

  • When working with a secured database, the database or one of its objects (such as a field or table) may be set to read-only. You may not have permission to access this data with your user name and password.

Close the database, resolve the read-only condition, and then reopen the file for read/write access. ACCESS SUPPORT RESOURCES
