Connecting to a MSSQL Database

[Nibor]

Hey,
Can someone please help me with this problem?
How can I connect to a MSSQL database which is not always the same i.e.
you connect to database "test1" and the other day to "test" for example.
Once you've started the compiled application you should chose which db you want to connect with.The db got a password too. After restarting the application the entered login and password data should automaticly be used to auto-reconnect to the db.
The only possibility to change the db and password should be given by some kind of key combination
like "ctrl+alt+1".

maybe someone can help me with this please.

regards.
