Thread: help convert code to C++...

Hi, i need some help convert my C# code to C++...im building a DLL file and the function to be exported...i believe there is something like __declspec(dllexport) but i do not know how to use it. Here is my code.

Code:

using System;using System.Collections.Generic;
using System.Text;
using Microsoft.Web.Services3.Security.Tokens;
using Microsoft.Web.Services3.Security;
using Microsoft.Web.Services3;
using System.Web.Services;
using System.Web.Services.Protocols;


namespace ClassLibrarySetupProcess
{
    public class Class1
    {
        public string callSetup(string msisdn, string contractid, string customerid, string accountind, string customercode)
        {
            DateTime dt = DateTime.Now;


            string datestr = String.Format("{0:yyMMddHHmmss}", dt);


           SetupService.SetupServiceService x = new  SetupService.SetupServiceService();
            SoapContext mycon = x.RequestSoapContext;
            UsernameToken tok = new UsernameToken("MGR1", "mg01Ch", PasswordOption.SendHashed);


            mycon.Security.Tokens.Add(tok);
            x.Dispose();


            SetupService.SetupServiceRequest mpInput = new SetupService.SetupServiceRequest();
            mpInput .ReferenceID = datestr + msisdn;
            mpInput .ChannelID = "CSSMBT";
            mpInput .ChannelMedia = "TTIVR";
            mpInput .TicklerIndicator = "2";
            mpInput .MSISDN = msisdn;
            mpInput .ContractID = contractid;
            mpInput .CustomerID = customerid;
            mpInput .CustomerCode = customercode;
            mpInput .AccountIndicator = accountind;
            mpInput .TicklerCode = "MBTFTP";
            mpInput .TicklerStatus = "NOTE";
            mpInput .TicklerShortDesc = "CLOVA VIA IVR";
            mpInput .TicklerLongDesc = "Temporary Unavailable";
            mpInput .TicklerPriority = "5";






            SetupService.SetupServiceResponse wseOutput = x.SetupService(wseInput);


            return mpInput.TransactionID + "|" + mpInput.ReferenceID + "|" + mpInput.ResultStatus.StatusCode + "|" + mpInput.ResultStatus.ErrorCode + "|" + mpInput.ResultStatus.ErrorDescription;




        }
    }
}
