MFC错误代码0000274d进入客户端服务器通信 [英] MFC error code 0000274d getting in client server commumnication

问题描述

你好朋友，

我已经使用CAsyncSocket类创建了一个客户端服务器应用程序.
我在客户端连接上收到错误代码0000274d.
谁能帮助我.当前只有单个客户端正在连接到服务器.

在此先谢谢您. 80).aspx> MSDN [ ^ ]返回代码:

 //  
//  MessageId:WSAECONNREFUSED 
//  
//  MessageText:
//  
// 由于目标计算机主动拒绝连接，因此无法建立连接.
//  
#define WSAECONNREFUSED 10061L  

MSDN:此功能通常由一次可能有多个连接请求的服务器(或想要接受连接的任何应用程序)使用:如果一个连接请求在队列已满的情况下到达，则客户端将收到一条错误消息，提示:指示为WSAECONNREFUSED."

aamswe说:
问题出在客户端上的套接字创建中.现在客户端正在连接到服务器.但是服务器没有从客户端接收消息.我有Voerriden OnAccept和OnReceive函数，当我从客户端发送消息时，捕获了OnAccept事件，但在OnRecive中没有发生.甚至我也尝试在OnAccept事件上接收消息，但接收到零字节.
可能是什么问题?

如果您正在运行Windows Vista/7，请打开ResMon.exe并转到网络页面.检查是否有与您的程序关联的会话或数据发送/接收.

如果您使用的是Vista之前的Windows版本，或者感觉很喜欢，请获取 Wireshark [ 解决方案

Look at MSDN[^] for return codes:

//
// MessageId: WSAECONNREFUSED
//
// MessageText:
//
// No connection could be made because the target machine actively refused it.
//
#define WSAECONNREFUSED                  10061L

MSDN: "This function is typically used by servers (or any application that wants to accept connections) that could have more than one connection request at a time: if a connection request arrives with the queue full, the client will receive an error with an indication of WSAECONNREFUSED."

aamswe says:
problem was in socket creation on client side. now client is connecting to the server. But server is not receving messages from client. I have voerriden OnAccept and OnReceive functions, When I am sending message from client, OnAccept event is captured but it''s not going in OnRecive. Even I tried to receive message on OnAccept event but zero byte recived.
What could be the problem?

If you are running Windows Vista/7 open ResMon.exe and go to the network page. Check to see if there is any sessions or data send/receive associated with your program.

If you are using a version of Windows previous to Vista, or you feel like it, get Wireshark[^] and start sniffing to see what is sent to/from the server.
