loading symbol

Question

Hi,

       I want to display the text  like "Loading" in a label.

       while I call a webservice method the can not be displayed even I set visible property to the label

       But when I am not calling the web service means it work fine.

       here is my code

 Private Sub save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

label1.text="Loading....."

  Label1.Visible = True

      Dim obj As New com.rem4ed.secure.rem4edsso_deskws //webservice

        Dim result As String = sec_ws.ssologincheck("[email protected]", "test")

        MsgBox(result )

        Label1.Visible = False

If I put message box after the line "Label1.Visible = True" it work fine

How can I display this?
