TextBox.Text to XML file

Question

I have a form with nearly 100 textboxes on it!. I know this seems like too many but there it is. The problem I have is, after text has been placed in the textboxes, I need a way to save this data to an XML file or something simpler if possible. I have tried to do this before and I may have succeeded but I can't remember what I did (old-timer's disease). If anyone can offer a suggestion for a decent primer in this particular area I would be grateful. Please do not direct me to the MSDN files as I don't understand half f what they are saying. My grounding in VB is a little shaky having largely been acquired "on the fly".
