I'm doing an app which is initially a C# WinForms app where the users will connect via VPN.
At some point in the future it will be converted to a web app, so I want to use a WS up front.

I'm fairly new at this, and I've seen some examples, as well as prior postings with you and Bonnie
that got me going this way.

I didn't think you could pass a dataset through a WS into the back end.
