How to change the connection string (server ip, user and password) of a MySql data source in Visual Basic 2010? (no replies)

Hi, I have a project where I added visually and successfully a datasource of MySql. I binded a datagridview with a table.

But, how do I change programatically the password, ip or user to connect with the MySql server? Because it can change at any time, so I can let the user change these values.
