Prevention of Multiple Users Editing

The program prevents two or more users from editing the same database simultaneously. When a user attempts to open a database that is currently being edited, a dialog listing the current "owner" is shown. The database is not available to other users until the current owner exits the database.

Note: This dialog may erroneously be displayed if, during the previous editing session with this database, the program abnormally terminated ("crashed"). When this occurs a temporary file used by the program to determine whether or not the database is currently being edited will not be properly deleted, and any attempts by any other user to access this database will result in this dialog being displayed, even though the database is not, in fact, currently being edited by the original owner. This problem can be resolved by having the original owner open, then close, the database. If the original owner is not available to open and close the model, the modelname~.usr file (where modelname is the name of the database) may be deleted from the data folder to allow another user to open the model. Only manually delete the modelname~.usr file if the owning user is not available and is not currently editing the file.
Warning: If one user is currently editing the database and the modelname~.usr file is manually deleted, a second user can then simultaneously access the database, resulting in data corruption. Only delete that file if no users are currently editing that database.
