谁有VS MFC 做的客户端向服务器发送图片的例子

谁有VS2005 MFC 做的客户端向服务器发送图片的例子。我可以做到服务器向客户端发图片，就是不知道怎么从客户端向服务器发图片！！！

[yaozhiyong110]

这有区别么？

[smwhotjay]

没区别. 改个收发. 就ok

是这样的，我想通过一台主机（服务器），控制其他主机（客户机）发送图片过来。现在就是可以通过服务器给客户端发，刚好反了（一个客户端对应多个服务器了）。

[yaozhiyong110]

如果你现在是客户端一连上来服务器就给客户端发图片 那么你改下 客户端一连上服务器就给服务器发不就行了? 无法理解为什么改不了...

下面是关键代码： 客户端： //创建Socket clientSocket=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP); if(clientSocket==INVALID_SOCKET) { MessageBox(L"Falied",0,0); return -1; } SOCKADDR_IN serverAddr; serverAddr.sin_family=AF_INET; serverAddr.sin_addr.s_addr=inet_addr(IP_ADDR); serverAddr.sin_port=htons(PORT); memset(serverAddr.sin_zero,0,sizeof(serverAddr.sin_zero)); ret=connect(clientSocket,(struct sockaddr*)&serverAddr,sizeof(serverAddr)); if(ret==SOCKET_ERROR) { MessageBox(L"Connect Falied:",0,0); return -1; } ofstream out("E://psb.jpg",fstream::out|fstream::binary); char buf[1024]={0}; while (1) { ret=recv(clientSocket,buf,1024,0); if(ret>0) { out.write(buf,sizeof(char)*ret); } else { out.close(); break; } } closesocket(clientSocket); WSACleanup(); 服务器端： //创建Socket serverSocket=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP); if (serverSocket==INVALID_SOCKET) { MessageBox(L"Create Socket Failed",0,0); } SOCKADDR_IN localAddr,clientAddr; localAddr.sin_family=AF_INET; localAddr.sin_addr.s_addr=inet_addr(IP_ADDR); localAddr.sin_port=htons(PORT); memset(localAddr.sin_zero,0,sizeof(localAddr.sin_zero)); ret=bind(serverSocket,(struct sockaddr*)&localAddr,sizeof(localAddr)); if (ret!=0) { MessageBox(L"Bind Error",0,0); } //服务器监听 ret=listen(serverSocket,10); if (ret!=0) { MessageBox(L"Listen Failed",0,0); } while(1) { //接收信息 int addLen=sizeof(clientAddr); clientSocket=accept(serverSocket,(struct sockaddr*)&clientAddr,&addLen); //cout<<"connect is success."<<endl; ifstream in("F://psb.jpg",fstream::in|fstream::binary); char buf[1024]={0}; while(!in.eof()) { in.read(buf,sizeof(buf)); ret=send(clientSocket,buf,1024,0); if(ret==SOCKET_ERROR) { //cout<<"Send Into error: "<<GetLastError()<<endl; //return -1; } } in.close(); closesocket(clientSocket); } closesocket(serverSocket); WSACleanup(); 你好，可以帮我看看吗？怎么改成客户端向服务器发图片？网络我不是很了解！！！

谢谢啊，解决了，看来要好好学学SOCKET编程！！！
