My problem is that I need to reference a database using just two bytes
(can't use a LocalID), and I'm wondering if using that 'index' I'm fine.. or
not.
The idea is sending as parameter this 'reference' (UInt16) and then loop
through the databases and get the LocalID again.... of course the database
will be opened all the time.
