You want to test the connection, db operations(SELECT, INSERT, etc.) that you have written in your VB.Net application with a mysql db. Isn't it ?
Then download the MySQL connector for ADO.Net: http://dev.mysql.com/downloads/connector/net/1.0.html

Install WAMP or XAMP or something like that in your machine. Turn it ON. Now, your db would be available under the host: "localhost", db name would be the name of the db that you have created (you could use phpMyAdmin for this), and use a db username and password that you have created for it or you could use the default ones when you install WAMP.

Then import the MySQL connector in your program and use it. An example is available here: http://stackoverflow.com/questions/6...answer-6190631

For the connection string, you could use this syntax: http://www.connectionstrings.com/mys...ysqlconnection

Like others said, I didn't get the idea of using a separate server/PC for testing. You could use the local server within that PC like I said above, or you could setup a Virtual Machine like others suggested.

Or, are you trying to figure out something specific ?
