I am making a connection to a webservice and the whole process takes about 15 seconds

While this time, the application is stuck (I'm programm for a device), so I have now changed to async webrequest which is working great!
Now I can Push the "Abort"-Button and it is asking if I want to stop the whole process. Before it asked only after the whole process

My problem is that I dont know how to end the async webrequest.

This is the async call:

                    Dim asyncCallback As New AsyncCallback(AddressOf FinishSum)
                    srvcon.BeginCheckRegistration(username, password, 1, 2, 3, asyncCallback, Nothing)
                    While a = ""         ' Here I am waiting for the result, while that I can press on Abort which sets Abbruch to true
                        If abbruch = True Then
                            GoTo gh
                        End If
                    End While

and this the result

    Public Sub FinishSum(ByVal IAsyncResult As IAsyncResult)
        a = srvcon.EndCheckRegistration(IAsyncResult)
    End Sub

But now if I exit it (goto gh), the webrequest is still running in another thread and returns after 15 seconds a value...
How can I stop it?
