sample c++ code

Hello,

I am quite a newbie in windows coding and I am trying to make a sample code in C++ running using gurux but... got nothing working.

I installed everything that was said in the readme.txt, and every component does compile fine.

Could you give us a full sample code using GXNET and GXSerial in C++ like the one given in C# please?

The code in C# I am talking about:
using System;
using Gurux.Common;
using Gurux.Serial;
using Gurux.Net;
using Gurux.DLMS2;

namespace GuruxCOSEMSample
{
public class GXCOSEMSample
{
// Device reply wait time.
int WaitTime = 5000;

private CGXCOSEM m_Cosem;

//Constructor.
public GXCOSEMSample()
{
m_Cosem = new CGXCOSEM();
}

///
/// Walk through all device objects using serial port connection.
///
pubic Gurux.DLMS2.CDLMSObjectCollection GetAllObjects()
{
GXSerial serial = InitializeSerialConnection();
CDLMSObjectCollection objs = GetObjects(serial);
return objs;
}

///
/// Initialize serial port connection to COSEM/DLMS device.
///
GXSerial InitSerial()
{
GXSerial serial = new GXSerial();
serial.Port = "COM1"; //TODO: Change correct serial port.
object reply = null;
byte Terminator = (byte)0x0A;
// Bitrate must be 300 when connection is initialized.
serial.BitRate = 300;
serial.DataBits = ByteSize.Byte7Bits;
serial.Parity = Parity.Even;
serial.StopBits = StopBits.One;
serial.Open();
//Query device information.
if (!serial.SendSync("/?!\r\n", Gurux.Common.VariantType.String, Terminator, 0, WaitTime, false, Gurux.Common.VariantType.String, out reply))
{
object d = serial.GetReplyData(Gurux.Common.VariantType.HexString);
throw new Exception("Failed to receive reply from the device in given time.");
}
string answer = reply.ToString();
if (answer[0] != '/')
{
throw new Exception("Invalid responce.");
}
string manufactureID = answer.Substring(1, 3);
char baudrate = answer[4];
int bitrate = 0;
switch (baudrate)
{
case '0':
bitrate = 300;
break;
case '1':
bitrate = 600;
break;
case '2':
bitrate = 1200;
break;
case '3':

break;
case '4':
bitrate = 4800;
break;
case '5':
bitrate = 9600;
break;
case '6':
bitrate = 19200;
break;
default:
throw new Exception("Unknown baud rate.");
}
//Send ACK
//Send Protocol control character
byte controlCharacter = (byte)'2';// "2" HDLC protocol procedure (Mode E)
//Send Baudrate character
//Mode control character
byte ModeControlCharacter = (byte)'2';//"2" //(HDLC protocol procedure) (Binary mode)
//Set mode E.
serial.SendSync(new byte[] { 0x06, controlCharacter, (byte)baudrate, ModeControlCharacter, 13, 10 }, Gurux.Common.VariantType.None, Terminator, 0, 500, false, Gurux.Common.VariantType.Array | Gurux.Common.VariantType.UInt8, out reply);
serial.BitRate = bitrate;
