How do you return a dataset from a client app.
I can program as label1.TEXT news feed to return a WebService but I can't
figure out how to return a dataset.
I declared the Namespace and Class
but how do you return the

What are you trying to do? Just get the DataSet from the Web Service? Is
this your actual code?

Something like
---
Dim oDS As DataSet
Dim oWS As New com.angrycoder.www.ContentFeed()
oDS = objService.GetHeadlines()
' use oDS for data binding in DataGrid
---
will do it and works fine here.

Hi Christian,
Thanks for your help again?
I'm getting an error here's my aspx below
I made a Datagrid and bound oDS to databinding as you stated but I'm getting
an error on line 14, the compiler doesn't like the datasource name.
Not sure what to do next?
