Currently, most of people use MS DCOM/COM+, Java Bean/RMI, and Corba to do distributed computing over internet. All of these technologies are provided with some tools and intermediate objects to simplify internet development. However, these technologies have one common and fundamental problem that all of the calls between a client and a server are blocked for a returned result (please correct me if this is wrong). A client stays still, and has to wait for a while after sending a request to a server. If the request is a lengthy action, the client application seems to be dead to a user. In most cases, we could use a worker thread at the client side to do background computation for solving this problem. However, this comes with an expensive price, more coding, data synchronization and mess in coding logic. Additionally, I also doubt that these technologies are able to really move data across internet efficiently.

1、实现多个网络调试助手示例在一个进程中启动； 2、可以实现TCP_SERVER,TCP_CLIENT,UDP，UDP组播通信；(1, multiple network example debugging assistant to start a process 2, can achieve TCP_SERVER, TCP_CLIENT, UDP, UDP Multicast communication )

该程序模拟知乎，作为网上问答系统，用户能注册，登录，提问，回答，点赞，关注，取关，查找问题，等一系列操作,一个服务器端可以同时连接多个客户端，能够同步各个客户端操作结果。程序分为客户端和服务器端，用户gui采用mfc编写，通信方式为socket方式，开发环境为win7 vs2015，编译器v140.(The program simulates know almost as online quiz system, users can register, login, questions, answers, thumbs up, focus on, take off, find the problem, and a series of operations, a server can be connected to multiple clients simultaneously, it is possible to synchronize each client operating results. Program is divided into client and server side, the user using mfc gui written communication for the socket, the development environment for win7 vs2015, compiler v140.)
