In my application, I am trying to allow the user to open any copy of the DBC they want and let them view those tables in the forms.

For example, my DBC name is Acme.dbc and this dbc contains several tables. However, the user can create a new Acme.dbc and fresh copies of it's tables in other directories.

How can I let my application know which Acme.dbc to open and also, when a form is opened, ensure that the tables from the desired Acme.dbc database are opened?

Here is my directory structure:
APPDIR\
\Acme1\
\Acme2\
\Acme3\

If a user chooses Acme.dbc from \Acme2\, I want only those tables to appear in the forms when the forms are called.

Thanks
