To connect to an MS Access/Jet database file, you can use this connection string:

"Provider=SQLOLEDB;Data Source=servername;Initial Catalog=databasename;User ID=user;Password=password;Network Library=DBMSSOCN;"

To connect to a MySQL server from MS Windows you need something like this (line wrapped):
