Hierarchical data

Hi

I'm a VB6 developer tasked with taking a VB6 application and turning it into
a .NET application. I'm just doing a bit of reading up at the moment...

The VB6 application does a lot of queries returning hierarchical ADO
recordsets, sometimes this goes as far as 4 chapters deep... This data is
not simply bound to a display control, but the data programmatically
iterated through and either the data manipulated or other tasks stared based
on the values found.

I'm after a quick "beginners" tutorial for handling hierarchical data and
manipulating it in a VB.NET environment. Any suggestions?

All help greatly appreciated.

Thanks

Griff,

Be aware that a datatable is almost the same as a recordset.
(Although the datatable is disconnected).

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemdatadatatableclasstopic.asp

A lot of people try to compare the dataset with a recordset, that is
impossible.

I hope this gives an idea?
