Hello:
I am trying to connect to a SAP system using IP. A dll  called ProxyIVA.dll 
created under .NET Framework 1.1 facilitates the connection. It works under 
C# without troubles in the next way:

using System;
using System.Web.Services;
using ProxyIVA;

namespace ConsoleApplication1
{
  class Class1
  {
  [STAThread]
  static void Main(string[] args)
  {
    string cs = "ASHOST= 111.11.1.11 SYSNR=00 CLIENT=300 USER=TEST 
PASSWD=x1x1x1x1";
    ProxyIVA.SAPProxy1 PIVA = new ProxyIVA.SAPProxy1(cs);
    ZHRRESNOMTable tIVA = new ZHRRESNOMTable();
    int sts =  0;
    PIVA.Z_Hrpfpa00105("20051231","03005358", out sts, ref tIVA);
   foreach (ZHRRESNOM r in tIVA)
      Console.WriteLine("{0}  {1}", r.Desc2, r.Betrg);
   Console.ReadLine();
   }
}
}


I try to do this in IP with the next results:
