cant consume NAV Web Service in C#.

Majestic

IM new on this forum, so bare with me if i posted this in the wrong forum.

Here goes...

I have been trying all sorts of ways to consume this web-service i have been given. Ill try and show you what i do to get where i am atm.

1. i start by adding the service reference in VS. everything goes as intended, i can see all the methods given to me.
2. to access the methods, and hopefully get some data, i do the following:

BMGWS ws = new BMGWS();

            Vogn vogn = new Vogn();
            VognType ty = new VognType();

            NetworkCredential cred = new NetworkCredential("username","Password","domain");
            ws.PreAuthenticate = true;
            ws.Credentials= cred;

            ws.SendVogn("BMG 2013", true, ref vogn);

            foreach (VognType c in vogn.Vogn1)
            {
                Console.WriteLine(c.RegNr);
            }

i get the following error: HTTP-status 401: Unauthorized.

I can say that the service i consume have a bunch of methods, only one method return a string, rest return void. the method that returns a string is working perfectly, but the "void" methods are not, im abit confused about that, so if anyone could shet some light on this i would get really happy.

any help would be much apreciated, since im kinda stuck

Did you expose your Webservice correctly? Can you access it in IE?

How does the URL look like that you added as Web-Reference?
Do you mind just trying ws.usedefaultcredentials = true?

i added a webservice by right clicking on my solution and chose "add webservice", and clicking advanced and adding a web referernce.

thereafter i get alot of services/methods added that i can use, as i explain above, there is only one method that sends somthing in return, my checkLogin method gives me a string in return if its a correct login that has been parsed. the other methods returns void eg nothing, that is confuesing to me.

Anyhow i tried what you said about the "ws.usedefaultcredentials = true" and it seems like it works with my login method. but does still not work with the rest of the methods.

my code atm looks like this:

ws = new BMGWS();
            Vogn vogn = new Vogn();
            ws.UseDefaultCredentials = true;
            ws.Url = "http:// adress:port/BMGLIGHT2013/WS/Admin/Codeunit/BMGWS";

            string s = ws.CheckLogin("string", "string", int);

            Console.WriteLine(s);

            ws.SendVogn("CRONUS AS", true, ref vogn);

            foreach (VognType c in vogn.Vogn1)
            {
                Console.WriteLine(c.RegNr.ToString());
            }

            Console.ReadLine();

my checklogin() works well, tho my ws.sendvogn() does not :-k - Its supposed to send me some 3 tables of data from NAV

At the moment i dont get any errors when building, but i get absolutly nothing in return from NAV.

If i add the service without adding it as a web reference, but as a normal Service refernce, i cant get my loginmethod to work... i get the error: The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'NTLM’

i use this code for my normal service reference:

BMGWS_PortClient ws = new BMGWS_PortClient();
            Vogn vogn = new Vogn();

            NetworkCredential cred = new NetworkCredential("Username", "Password", "domain");
            ws.ClientCredentials.Windows.ClientCredential = cred;

            string s = ws.CheckLogin("string", "string", int);

            Console.WriteLine(s);

hope you can help!

and yes, i can access it in internet explore

here is the XML of the SendVogn:

<element name="SendVogn">
<complexType>
<sequence>
<element minOccurs="1" maxOccurs="1" name="comp" type="string"/>
<element minOccurs="1" maxOccurs="1" name="inaktiv" type="boolean"/>
<element minOccurs="1" maxOccurs="1" name="bMGVogn" type="q4:Vogn"/>
</sequence>
</complexType>
</element>

I have solvedmy problem! the fix was:

ws.SendVogn("BMG 2013", true, ref vogn);

there was no test data in the database with the Bool value true, changed it to false and it worked, my working code looks like this:

BMGWS ws = new BMGWS();
            Vogn vogn = new Vogn();
            
            ws.UseDefaultCredentials = true;

            Console.ReadKey();
            ws.SendVogn("BMG 2013", false, ref vogn);

            foreach (VognType c in vogn.Vogn1)
            {
                Console.WriteLine();
                Console.WriteLine(c.Beskrivelse);
                Console.WriteLine(c.Kode);
                Console.WriteLine(c.RegNr);
                Console.WriteLine(c.Spaerret);
                Console.WriteLine();
            }

it works perfectly!
