Linked Table Manager and Network Drives

[MC77]

I am developing an application using a database on a local drive(c,without access to a network. The app is then deployed to the user, we use the Linked Table Manager process to connect the app to the backend database. This is currently functioning as a manual effort...but is there a way to include this link to the network database when I create the .mde and bypass the manual linking effort?
Thanx

This does the same thing, but deletes each attached table first. It also checks against a constant gcUserDataFileNm, which is the path to a local db if you want to attach some user info. If all your back-end tables are in the same mdb, remove that line to check. It furthermore writes the name of the attached file to a table called utblSysAdmin, you can get rid of that part of the code, too (look for the rst stuff near the end).
