vc++ - socket is not writing into the port

I am trying to create a ftp client with uploading a file capability. But the socket is not sending the message into the server, even though it got the connection with the server. See the code below

#include <iostream>
#include <string>
#include <tchar.h>
#include <Winsock2.h>

#include <winsock2.h>
#include <ws2tcpip.h>
#include <stdio.h>
#include <stdlib.h> 

int main(int argc,wchar_t * argv[])
{

    WSADATA wsaData = {0};
    int iResult = 0;

    iResult = WSAStartup(MAKEWORD(2, 2), &wsaData);

    if (iResult != 0)
    {
        wprintf(L"WSAStartup failed: %d\n", iResult);
        return 1;
    }

    SOCKET sock= socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
    if (sock == INVALID_SOCKET) 
        wprintf(L"socket function failed with error = %d\n", WSAGetLastError() );
    else
        std::wcout << " Success occured in socket creation " << std::endl ;

    SOCKADDR_IN sock_Addr={0};
    sock_Addr.sin_family=AF_INET;
    sock_Addr.sin_port=htons(21);
    sock_Addr.sin_addr.S_un.S_addr=inet_addr("10.0.0.105");

    char recv_Buf[1000]={'\0'};
    if(connect(sock,(SOCKADDR *)&sock_Addr,sizeof(SOCKADDR_IN)) != 0)
        std::cout << " Error in connection " << std::endl ;
    else
    {
        std::string tmp;
        u_long mode =1; // non blocking socket
        ioctlsocket(sock,FIONBIO,&mode);
        int result = recv(sock,recv_Buf,sizeof(recv_Buf),0);
        while( result > 0 )
        {
            tmp=tmp+recv_Buf;
            result = recv(sock,recv_Buf,sizeof(recv_Buf),0);
        }
        std::cout << "connection - success - " << tmp << std::endl ;
    }

    ioctlsocket(sock,FIONBIO,0);
    st开发者_StackOverflow中文版d::string buf="USER administrator";
    if(send(sock,buf.c_str(),buf.size(),0)== SOCKET_ERROR)
    std::cout << " sending user - error  " << WSAGetLastError() << std::endl ;
    else
    {
        std::string tmp;
        u_long mode =1; // non blocking socket
        ioctlsocket(sock,FIONBIO,&mode);
        int result = recv(sock,recv_Buf,sizeof(recv_Buf),0);
        while( result > 0 )
        {
            tmp=tmp+recv_Buf;
            result = recv(sock,recv_Buf,sizeof(recv_Buf),0);
            std::cout << "received " << recv_Buf << std::endl ;
        }
        std::cout << "user - success - " << tmp << std::endl ;
    }
}

Note : I am using filezilla To check this . It will show the incoming connections and the commands. So if anybody guide me in this issue, I will be thankful to you.

Edit Below is the client side(my side) command prompt result

FTP commands are terminated by a carriage return - line feed pair (\r\n). You need to add \r\n to your USER command string.

Edit: you should consult RFC 959 for more information (there's more FTP-related RFCs that update and extend RFC 959 too). It has a section detailing the base FTP commands and shows the expected format, including <CRLF> pair.
