 Hello,

 I'm trying to connect to a web service method hosted in Sharepoint . When i did it from the program i'm allow to get result cut when i do it on FormEvents_Loading method, it doesnt give me any result but unfortuantely it doesn´t give any error too.

 FormEvents_Loading code

 

       public void FormEvents_Loading(object sender, LoadingEventArgs e)
        {

    
                WebServiceConnection connection= (WebServiceConnection)this.DataConnections["getAttachs"];


                XmlDocument inputDoc = new XmlDocument();
                XmlDocument outputDoc = new XmlDocument();
                XmlDocument errorDoc = new XmlDocument();

                // Create the XPathNavigator objects for the documents
                XPathNavigator inputNav = inputDoc.CreateNavigator();
                XPathNavigator outputNav = outputDoc.CreateNavigator();
                XPathNavigator errorNav = errorDoc.CreateNavigator();

connection.Execute(inputNav, outputNav, errorNav);

                XPathNodeIterator outIterator = outputNav.CreateNavigator().Select("/dfs:myFields/dfs:dataFields/ns1:getAttachsResponse/ns1:getAttachsResult/ns1:string", NamespaceManager);
          
               }
           

outIterator.count always return 0 value ,so it seems that it never fills a iterator. 

 Someone have any idea that why happens this?

 Thanks,

 Regards           

 

The code in your post won't actually compile, will it? You are using inputNav, etc prior to actually executing the connection?

Oh my god! Sorry. I forgot to paste execute action and then i pasted it in wrong place.

 I edit my first post with correct code. 

Thanks for your answer

 Regards

 

I'd put some breakpoints in the code and run in debug so you can check the errorNav and the outputNav. Here's some help on how to do that in case you need it.

 Thanks! VSTA debuger is very cool.

My problem wasn't in connection but i had outIterator always null. This happened because outputnav navigator returns  only [ns1:getAttachsResponse/ns1:getAttachsResult/ns1:string] so i have to select only that XPath.

 Thanks for your answers Hilary.

 Best regards

It is amazing how much easier it is write code when you can run in debug and figure out what your mistakes are, and it is something I think is often assumed (incorrectly) that everyone already knows this....
