Answer 1

In general you should use the native ADO.Net MySql drivers available here: http://dev.mysql.com/downloads/connector/net/6.2.html. These offer much better performance and support more features than the generic ODBC driver.

Your error is in the connection string. Did you set up an ODBC data source on your computer? The ODBC driver needs this to connect.
