Simple XML settings file reading and writing - newbie

Hello,

I dont have much experience with vb.net and i need some help.

I have a form that has a few text boxes for entering in credentials to connect to a mysql database.

I want to have the settings read from an xml file when its loaded, and written to the xml file when its closed.

I also want to put as much of the reading and writing code in a module, and call it from the form when needed.

Can someone please give me a basic guide and/or examples to achieve this?

thanks,

bryan
