Solution 1

There should be a callback delegate.

AddHandler service.GetUserComplete AddressOf GetUserCompleted

Then add a method that handles this callback.

VB

Private Sub GetUserCompleted(sender As Object, e As ServiceReference1.GetUserCompleteEventArgs)
  'Access e.Results here
End Sub

Add the handler inside Button1_click.
