Problem consuming a MII BLS as a Web service. No data getting displayed

Question

Hi experts,
I am trying to consuming a MII BLS as a Web service from Visual Basic .Net 2010. But its a failure. I am unable to view any data on the VB grid. I did piece of code referring to the article in
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/b0563b23-be97-2b10-02a0-fb8fac9ab39e
I am totally new developer in Microsoft products. Here is the code that I used from the above white paper.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim wsVcValues As New SapVcValues.XacuteWS
        Dim myInParams As New SapVcValues.InputParams
        Dim varResult As SapVcValues.Rowset
        'Pass your input parameters to the transaction
        myInParams.Plant = "1000"
        'Now lets call the transaction using the guest account
        varResult = wsVcValues.Xacute("guest", "guest", myInParams)
        DataGridView1.DataSource = varResult.Row
        DataGridView1.Refresh()
        varResult = Nothing
    End Sub
End Class
Here are some deviations when compared to the above article.
1. Used MII 12.1 transction.
2. Used VB .Net 2010 as the development environment.
The transaction that I used has 1 action with simple query which returns the o/p xml.
Please help! I am stuck.
Regards,
Rajesh.

Hi Jeremy,
You are right. I am getting a log in page when try to call the WS from the browser. I unchecked WSDLGenSecurityEnabled option. Now I am not redirected to log in page. But I am not getting the required output in the XML.
I am using SAP MII 12.1Service Pack 6.
Please find the XML the is getting displayed when I call the WS from browser below:
