Using external webservice from custom module

Hello,

I'm using DNN for some time now and I'm developing a custom module using an external webservice. "Normally" I would add a Web Reference to the solution and from there I can access the methods automatically insight my aspx files. I searched around a lot and read a lot of articels but I cannot find how to connect to the external webservice from my DNN module.

Can someone get me started here, preferrably using VB? I downloaded already the Iowa Weather Service iowacomputergurus.com/free-products/dotnetnuke-modules/dnn-weather-conditions-service-module.aspx as an example to see if this would set me off but sadly no succes so far.

Re: Using external webservice from custom module

Hi Arjan,

are you connecting to a WCF web service or to an ASP .NET asmx web service? I successfully connected to both using the standard way. For example to connect to my WCF service I add the reference and use:

Imports System.ServiceModel
Imports MyWCFServiceReference
Imports System.Windows.Data

Private Sub CallWebService(Parameters)
Dim MyEndpointAddress As New EndpointAddress("WebServiceURLGoesHere")
Dim MyBinding As New BasicHttpBinding 'Or whatever you need
Dim proxy As New MyWCFServiceReference.MyWCFServiceClient(MyBinding, MyEndpointAddress)
AddHandler proxy.DoWorkCompleted, AddressOf DoWork_Completed
proxy.DoWorkAsync(Parameters)
End Sub

and

Protected Sub DoWork_Completed(ByVal sender As Object, ByVal e As MyWCFServiceReference.DoWorkCompletedEventArgs)
' get results form e.Result
End Sub

Remember that accessing cross domain services requires the cross domain policy xml file to allow this. Let me know if you need the asmx code or if you need further help.

Best regards,
Dario Rossa

Re: Using external webservice from custom module

Hello Dario,

thank you for your reply.

I can get it to work in DNN using the standard ASP.NET methods : Add Web Reference, import service in vb module (in my dnn cusom module) and use the methods from the webservice.

Do you - or someone else - have guidelines/books/ documents/ how-to if I want the following: Create DNN Custom module and consume an external ASP.NET asmx web service?

All insight one custom module that i can export and reuse in other DNN sites?

Greetings,

Arjan
