Thread: trying to send a struct over a socket

i am not seeing a = 50; b = 100; c = 200; in the recv buffer, i am only seeing a = 50;
what is the problem?

Code:

// tcp.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <vector>
#include <windows.h>
#include <iostream>
#include <list>
#include <stdio.h>
#include <d3dx9.h>
