How do I connect to local MSSQL database?
Use the following script
<add name="strConn" connectionString="Data Source=localhost\sqlexpress;Initial Catalog=DBNAME;Integrated Security=false;User ID=DBUSERNAME;Password=DBPASSWORD" />
DBNAME is what you specified as your database name in the control panel
DBUSERNAME is the username you created to connect to the database (and was associated with the database in the control panel)
DBPASSWORD is the password you associated with the username above
