Re: cannot open default page. error connecting to database

In some of the ways, spacing and the order of parameters in the MySql connection string does matters. So, stick to the standard format:

MysqlConn.ConnectionString = "Server=localhost;Port=1234;Database=My_Mysql_Database;Uid=root;Pwd=root;"

If the above connection string fails, try update your connection string as shown below (without port variable as well):

MysqlConn.ConnectionString = "Server=localhost;Database=My_Mysql_Database;Uid=root;Pwd=root;"

Or, sometime the problem could be on your windows firewall, make sure your server allow access to all port associated with your mysql database.
