Thread: Problem with Send packet at hooked recv/send

Hey guys why this source doesnt work for me? Please help me whats the mistake?

If the programm start with the injected dll, it crash and i get a windows error. More i dont know.

Code:

// dllmain.cpp : Definiert den Einstiegspunkt für die DLL-Anwendung.
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>
#include <windows.h>
#include <winsock2.h>

#pragma comment(lib,"ws2_32.lib")

using namespace std;

typedef int (WINAPI* realRecv)(SOCKET socket, const char* buffer, int length, int flags);

realSend o_send;
realRecv o_recv;
realConnect o_connect;

SOCKET Bot;

int WINAPI my_connect( SOCKET s, const struct sockaddr* name, int namelen)
{
	WORD port = ntohs((*(WORD*)name->sa_data));
	sockaddr_in *sockaddr = (sockaddr_in*)name;
	sockaddr->sin_port = htons(16000);
	if ( port != 80 )
	{
	sockaddr->sin_addr.S_un.S_addr = inet_addr("127.0.0.1");
	}
	return o_connect(s,name,namelen);
}

	return o_send(socket, buffer, length, flags);
}

	return o_recv(socket, buffer, length, flags);
}

this is source code packet editor right?

may u put your promblem?..
what's going on with you code?..
maybe its help someone who want helping you..
