Hi Rodney,
You might consider having a free "configuration" table for your app (not part of a DBC, and maybe compiled into the app) that holds various information -- including the name and location of your data DBC. Then, you'd write some code that checks the table for the value and opens the desired DBC.
Alternately, you could pass as a parameter the name/location of the DBC to your app each time you run it, and use (basically the same) code to check the value for correctness and open the DBC you want.
HTH.
