我尝试建立客户端服务器连接，我尝试从客户端发送数据并由服务器接收。我从互联网上修改程序，但结果并不令人满意。客户端和服务器之间的连接已经建立，但是客户端不能向服务器发送数据。

有人能告诉我这些程序有什么问题吗？

服务器

 #include <Windows.h>
 #include <iostream>

 using namespace std;

 SOCKADDR_IN addr;
 SOCKET sListen;
 SOCKET sConnect;
 SOCKET Connections;

 int addrlen = sizeof(addr);
 int ConCounter = 0;
 struct Buffer
{
char Message[256];
};


int InitWinSock()
{
int RetVal = 0;
WSAData wsaData;
WORD DllVersion = MAKEWORD(2,1);
RetVal = WSAStartup(DllVersion, &wsaData);

return RetVal;
}

 int main()
 {
int RetVal = 0;
RetVal = InitWinSock();
if(RetVal != 0)
{
    MessageBoxA(NULL, "Winsock startup failed", "Error", MB_OK | MB_ICONERROR);
    exit(1);
}

Connections = (SOCKET)calloc(1, sizeof(SOCKET));
sListen = socket(AF_INET, SOCK_STREAM, NULL);
sConnect = socket(AF_INET, SOCK_STREAM, NULL);

addr.sin_addr.s_addr = inet_addr("127.0.0.1");
addr.sin_port        = htons(1234);
addr.sin_family      = AF_INET;

bind(sListen, (SOCKADDR*)&addr, sizeof(addr));

listen(sListen, 1); 

for(;; Sleep(50))
{
    if(sConnect = accept(sListen, (SOCKADDR*)&addr, &addrlen))
    {
        cout<<"connection was found";

        for(;; Sleep(50))
{
        Buffer sbuffer;
        char* Recv = new char[256];
        ZeroMemory(Recv, 256);      
        if(recv(Connections, Recv, 256, NULL))
        {       
            cout<<Recv<<endl;           
            ZeroMemory(Recv, 256);
        }
        }               
    }
}
return 0;
}

recv(Connections应该是recv(sConnect。请参阅我对您的问题的评论，以获取代码中其他更小错误的列表。
