Answer 1

From what I can gather you want to connect to a different database instead of "MyDatabase.sqlite". You just need to change the "Data Source" to point to your database.

m_dbConnection = new SQLiteConnection("Data Source=c:\myexistingdb.db;Version=3;");

You may want to check out connection strings, if you need username, passwords, etc.
