I was thinking the same thing about it being easy since my test web service app worked and it was easy to get up and running but I have no idea on how to start with my mobile app calling the IWeb method.  This is where I am stuck.  How do I make my mobile app communicate with the IWeb method?

So I have reviewed the link above and added another method as described but do not see it in my list of WebService list when I navigate to http://mydomian/DesktopModules/IWeb/webservice.asmx

Here is my code for the service:

Imports Microsoft.VisualBasic
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.Linq

Namespace DotNetNuke.Modules.IWeb
    Public Class IWebMyTest

        Partial Public Class WebService
            <WebMethod(Description:=" GetTagGuid *DotNetNuke* |IWEB Core| #IWEB Misc# !Portal! "), SoapHeader("IWebCredentials")> _
            Public Function GetTagGuid(ByVal TagId As Int64) As VBData.iTag
                Dim db As New VBData.MyDataContext
                Dim tag = From t In db.iTags _
                          Where t.itag_id = TagId _
                          Select t.itag_id
                Return tag
            End Function
        End Class
    End Class
End Namespace
