>I'm using two databases with the exact same structure. (The data is coming from different input sources.) On my preference form I have a checkbox to use either one data source or another. Is there a method to set the default database? I know there is a method to read the default database in the databasemanager class, but is there a method to reset the default database and then use it?>

When using data sets, it's probably easier to simply set a filter on metadbc in your preference form.
