>I have an application that I wish to allow users to create a duplicate of the databases and tables. For example a multi office application where the underlying information is completely different but the dbc/tables/application are exactly the same. I have coded to allow the users to select between datasets by creating separate subdirectories and datasets beneath the application main directory. Now I want to programatically copy the database & related tables to a subdirectory if a user wants to add a new office to their application.

I can easily validate the new database with "recover" through the command prompt then manually reply 'yes' to resolve the back link messages but I would like to automate this process so it is invisible to the users.

Another general approach might be to use the GenDBC program. When you run this against your original database it creates a program (e.g. "BuildMyDBC.prg") that, when itself run, can re-create your database. It might be possible to modify BuildMyDBC.prg to reflect the new name required.

As an alternative it's probably possible to use low-level file functions and programmatically modify file headers in tables to point to a differently-named .DBC. I don't know how to do that but you might find the answer by searching through threads here.
