Dear forum experts,
I have developed an application which uses ODBC32 to access a MS Access database.
I was tell by someone that when the database is acceded by 2 ODBC clients on 2 different computers, if the first computer is shut down, the database connection is lost for the second one.
I first thought that MS Access was only a local database server, but reading the documentation, I have seen that it was really possible to be multi-clients.
Did someone have an explanation for the described behavior (second to connect is de-connected from database when first one is de-connected), Is there something missing in the DBConnection()? It may be more a database problem that a labwindows Cvi one but I don't know how to handle this.
Best regards,
Serge

Access is not a multiuser and not even a real remote database. While some drivers may support network transfer, the actual Access DB engine only supports a single client. Guaranteeing concurrent access to data doesn’t corrupt the data in the DB is a very difficult problem to solve. Access chose to avoid that problem by not allowing concurrent access!
