Since this morning I am stuck!!
I dont know what is wrong!

I have build anweb service which work fine
But when I build a windows application which call my web method of the web service
It happen nothing.
In fact my two methods are a retrieve data and an update data
when I click to the retieve data button it don't happen anything and when i debug I can see that the program call the web method and go back to the button sub.

here is a piece of my code from the web service

<WebMethod()> Public Function RetrieveData() As Dataset1

Dim DataBag As New Dataset1()
Return DataBag

End Function

here is a piece of my code from the Winform

Private Sub btnRetrieveData_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRetrieveData.Click
Dim ws As New WindowsApplication1.localhost.Service1()
ws.Credentials = System.Net.CredentialCache.DefaultCredentials
End Sub

If someone know what happen to me, please tell me....
