Webservice call with .NET from Nav: strange error

  Here the Exception.ToString() output:
  
  System.Net.WebException: De server heeft een fout in het protocol veroorzaakt. Section=ResponseStatusLine
  
  bij System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request)
  
  bij System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request)
  
  bij System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
  
  bij LogicsWebService.zdlLogicsWebService.Service.AddArticle(String articleCode, String articleName)
  
  bij LogicsWebService.LogicsWebService.AddArticle(String artCode, String artName)
  
  
  I use authentication: clsService.Credentials = new System.Net.NetworkCredential(m_userID,m_password);
  
  The authentication works well, cause the first calls from Navision were with a invalid user/pwd and that results in the error "401 - unauthenticated" or something like that.
  
  [edit] Correction on the authentication. If I mess up the login/pwd, I still get the ResponseStatusLine error. But my C# testapp does work fine with the latest webservice dll.[/edit]

  Navision code:
  
  IF ISCLEAR(clsWS) THEN
  CREATE(clsWS);
  clsWS.UserID := uID;//=Text: qqq
  clsWS.Password := pwd;//=Text: yyy
  iResult := clsWS.AddArticle(artCode,artName); // 2x Text: X and Y, result = Integer
  CLEAR(clsWS);
  
  
  C# code:
  
  public int AddArticle(string artCode,string artName)
  {
  this.SetCredentials();
  
  try
  {
  return clsService.AddArticle(artCode,artName);
  }
  catch(Exception e)
  {
  System.Windows.Forms.MessageBox.Show(e.ToString());
  
  return -1000;
  }
  
  }
  
  
  C# code part from the Webreference/wsdl.exe:
  
  [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://LogiqsAgro.com/AddArticle", RequestNamespace="http://LogiqsAgro.com/", ResponseNamespace="http://LogiqsAgro.com/", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
  public int AddArticle(string articleCode, string articleName) {
  object[] results = this.Invoke("AddArticle", new object[] {
  articleCode,
  articleName});
  return ((int)(results[0]));
  }

  Hey BlackTiger, I applied the [...] stuff from your example and it works! But the thing that raises my eyebrows is that the original code also works!
  Beats me! Thanks 100x anyway!
  
  One little thing that you might also know: Every time I registered the modified dll I get a new entry in the automation server list in Navision. If I unregister the dll with regasm xxxx.dll /u, the entry is not selectable in Navision, but is still there. I register with regasm xxxx.dll /t. Is it possible to use the same entry over and over?
