How use Data Tables with XML Files in Visual Basic VB.Net

In this lesson we show how to combine VB Data Tables with external XML Files so that we have permanent XML Storage of the data in the Tables.

If you have not used Data Tables before, you are in for a real treat.
VB Data Tables really unleash the power of Object Oriented Programming and are by far the best method of dealing with XML File Processing.

In the lesson we setup and then use a Data Table to enter some summary data for Players in a Tennis Dream Team, and then save the whole dataset permanently to an external XML File.

Give these resources to your students and we think you will find that some of them will "get it" very quickly.
The other students need to watch this video which goes through everything in full detail slowly step by step with repetition of examples.

This is a detailed video, if you want to fast track learning about working with XML Files, then just Download and quickly read through the PDF of the Presentation using the Link given further down below.

Then for anything you do not fully understand in the PDF document, simply use the Timeline Index below to go and watch the relevant section of Video explanation.
