did you add the following to the web.config

<compilation>
      <codeSubDirectories>
        <add directoryName="Widget"/>
      </codeSubDirectories>
</compilation>

I came across this thread via Google search because I had almost the same situation as MatteS. I'm not new to the .NET framework, but I'm new to DotNetNuke module development. Well, after much research and several days of frustration, I finally figured out how to deploy a web reference in a module, so I thought I'd share.

Actually, junyen was on the right track, but most of us starting out with DNN or the .NET framework aren't going to know what he meant when he said to create a proxy class for your project. In case you don't know, a web reference proxy class is a code version of a web reference. The web references are usually located in your App_WebReferences folder, but if you make a code version of it, you can move the code wherever you need it. To create the proxy class, you need to use a tool called wsdl.exe, which comes with Visual Studio 2005. To use it, click Start => All Programs => Visual Studio 2005 => Visual Studio Tools => Visual Studio 2005 Command Prompt. Navigate to where you want the output code file to go and type:

wsdl http://www.[yourwebservicesite].com/[yourwebservice].asmx?wsdl /namespace:[YourWebServiceAlias] /out:MyWebService.vb /language:VB

Replace the text in brackets with your own information that pertains to your web service. You should use the same namespace as the alias you called your web reference when you linked to it. So, if you called your web reference MyWebService, the namespace you use in the wsdl command should be the same. Otherwise, you'll need to update your calling code to reference the new namespace.

Copy output file (MyWebService.vb) to your module's folder in the App_Code folder. Now you can remove the web reference from your App_WebReferences folder and test to make sure your module still works. Once you've verified this, you're ready to package and deploy your module. When you hit Build => Publish, the proxy class you created will be rolled into the dll that gets created for your App_Code folder.

Here's more info on the WSDL.exe tool:

Hi There,

I seem to have a problem using MS MapPoint Webservice in my DNN module. I was wondering if any of you chaps might be able to help....

The module i am writing is based around code supplied in the MS MapPoint SDK and works perfectly in a standalone project.

I then downloaded the VS2005 DNN 4.5.3 Starter Kit and installed that - all worked perfectly.

I then used the Starter Kit to add a DNN module template to my project - again, all worked perfectly.

I then added the MapPoint Web Reference to the project at DNN level  just to try and get it working

I then migrated all the code from the standalone project into the DNN module and it compiles with no errors.

But, when i run the project and try and create a map it pukes with the error :

System.MissingMemberException was unhandled by user code
  Message="Public member 'FindServiceClass' on type 'global_asax' not found."
  Source="Microsoft.VisualBasic"

       at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

when running the following code:

Try
myFindResultsPointA = ParcelRoute.FindServiceClass.FindAddress(findAddressSpecA)
Catch myException As SoapException
'Your exception handling goes here
End Try

I have been talking in depth with Mike Lancaster, who writes the DNN Module Development guide and he thinks it's something to do with DNN. He commented:

"I think it is failing because DotNetNuke is running under partial trust and it need full trust. But I'm way out of my comfort zone at this point. Hopefully someone has an answer."

Previous Thread is at: http://www.dotnetnuke.com/Community/Forums/tabid/795/forumid/111/threadid/145061/threadpage/1/scope/posts/Default.aspx

From what I can see the functions are in a global.asax.vb in my \app_code\ParcelRoute directory. Which is where Mike said it should be...

Have you got any thoughts on what might be going wrong please?

(Also, I tried doing what was mentioned in the posting above but it says that the asmx file is not found... weird.... never mind. I think it should work as it is using the Web Reference at DNN level although I will have to fix this problem before i can make it into a PA) 

Below is a copy of the code in my global.asax.vb
