OK I am starting to understand. Basically the service does return XML

Now I need to find a good tutorial on all this stuff.

Thanks again for clearing this up for me.


Just to reiterate, a web service can return a DataSet. It will actually be XML
data, following Microsoft's diffgram XML schema, but for all intents and
purposes, it is a dataset.

The client can call the method that returns a dataset, perhaps passing some
parameter values, and assign the return value to a dataset variable. As you put
it, all the xml processing happens automagically.

It can be a bit bulky for returning many rows, since the column names will be
repeated twice for each row in the actual XML, but it works very smoothly.
