مشکل با برنامه نویسی سوکت

[NIMA_1981]

سلام دوستان میشه بگید چرا این 2 تا کد کار نمیکنه

کد سمت کلاینت

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <string.h>
#include <winsock2.h>
#define DEFAULT_IP "127.0.0.1"
#define DEFAULT_PORT "4323"
#pragma comment(lib, "Ws2_32.lib")
//define main function
int main(int argc, char **argv){
WSADATA wsaData;
SOCKET intSocket;
struct sockaddr_in recSin;
char *pchrBuffer;
int intErr;
int iResult;
// Initialize Winsock
iResult = WSAStartup(MAKEWORD(2,0), &wsaData);
if (iResult != 0) {
printf("WSAStartup failed: %d\n", iResult);
return 1;
}
//Create a Socket
recSin.sin_addr.S_un.S_addr=inet_addr(DEFAULT_IP);
recSin.sin_family=AF_INET;
recSin.sin_port=htons(atoi(DEFAULT_PORT));
intSocket=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
if(intSocket== INVALID_SOCKET){
printf("\nError on Create Socket\n");
WSACleanup();
}
intErr=connect(intSocket,&recSin,sizeof(recSin));
if(intErr==INVALID_SOCKET){
printf("\nError on Connect to Socket\n");
printf("failed: %d\n", WSAGetLastError());
WSACleanup();
exit(1);
}

// Send And Recive Data
pchrBuffer="naeim\0";
intErr=send(intSocket,pchrBuffer,strlen(pchrBuffer ),0);
if (intErr == SOCKET_ERROR) {
printf("send failed: %d\n", WSAGetLastError());
WSACleanup();
exit(1);
}

printf("Bytes Sent: %d\n", intErr);

قسمت ارسال اطلاعات درست کار میکنه اما برای دریافت این خطا رو میده 10057 که این میشه


Socket is not connected. A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using sendto) no address was supplied. Any other type of operation might also return this error—for example, setsockopt setting SO_KEEPALIVE if the connection has been reset.

کد زیاده و debug سخت شما http://www.codeproject.com/Articles/20947/Hello-world-application-for-socket-programming-in رو نگاه کنید شاید مشکل حل شد
