ado.net tutorials

I worked through the two tutorials profided on the vb express page (numbers 8 and 9). But now I want to know more about the dataset, bindingsource and tableadapter. How do I add a row to the dataset with values entered in a textbox and DateTimepicker? How to I let the dataset update to the database? Of course with code examples and all. As I understand this whole thing is called 'Ado.net'. So basically I'm looking for SIMPLE tutorials about ado.net. I've looked at different sources but all are complicated and not to the point (setting up a SQL server,etc, i'm just trying to work with the SQL express edition included in Visual Basic express).

WHo can point me in the right direction?
