Hi,

I have created a web service, deployed it and configured with iis. If i access that http://xxx/webService/ the page will come up with the web method name as links.

If i enter the input and Invoke, It will display the results.

This web method is returning a dataset.

In my application, i am adding a web reference and binding this web method to a dataset

Dim serv As xxx.Service1
Dim ds As New DataSet()
ds = serv.GetSerial(serialno)

But on this line ds = serv.GetSerial(serialno) i am getting an error Object reference not set to the instance of the object.

Do i need to add anything in the web.config file??

Please help me out.

Many Thanks,
Anu
