Im currently writing an application in VC++ .Net and happen to have a single header file for a TCPClient class:

using namespace System;
using namespace System::Net;
using namespace System::Net::Sockets;

__gc class cTCPClient{

    int targetPort;
    bool readData;
    bool DONE;

            readData = false;
            DONE = false;

      String* sendData(String* serverName, int port, String* data){
            String* dataReceived;
                  TcpClient* tcpClient = new TcpClient(serverName,port);
                  //Create a NetworkStream for this tcpClient instance.
                  //This is only required for TCP stream.
                  NetworkStream* tcpStream = tcpClient->GetStream();
                  if (tcpStream->CanWrite){
                        Byte inputToBeSent[] = System::Text::Encoding::ASCII->GetBytes(data->ToCharArray());
                        tcpStream->Write(inputToBeSent, 0, inputToBeSent->Length);
                  while (tcpStream->CanRead && !DONE){
                        //We need the DONE condition here because there is possibility that
                        //the stream is ready to be read while there is nothing to be read.
                        if (tcpStream->DataAvailable){

                              Byte received[] = new Byte[512];

                              int nBytesReceived = tcpStream->Read(received, 0, received->Length);

                              dataReceived = System::Text::Encoding::ASCII->GetString(received);

                              DONE = true;
        }catch (Exception* e){
            return dataReceived;

The original code was in C# from here:

I simply converted it to C++ and made a few small changes. The sendData function sends a string to the specified IP address and returns a string containing the response.

Hope this helps!
