I think this could be useful to some people as I saw a lot of questions about it. Please excuse my English.

This are the step a followed to access a webservice (asmx) from a module:

First, get a simple module that is working OK, I use a sample from a book, can be one created from the StarterKit template.

I use VisualStudio 2008. With the module project loaded add a webservice reference as usual, nothing new here (I called it "ws").

VisualStudio will add a web.config file to the project, delete that file !!

To reference the webservice methods I use this code: (let say the webservice is named "webservice1" and have a method named "method1")

    Private wservice As ws.webservice1

    Public Function WebService() As ws.webservice1

        If wservice Is Nothing Then

            ' Create web service proxy

            wservice = New ws.webservice1

            wservice.Url = "http://............. /webservice1.asmx"

        End If

        ' Return the service proxy

        Return wservice

    End Function

   '....Calling a method....

    WebService.method1
