MD5 (Message-Digest algorithm 5) is a widely used, partially insecure[1] cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically expressed as a 32 digit hexadecimal number.

这是完整的一个C/S的客户服务端程序！但是我希望加点功能！请大家帮帮忙，“我要做的是客户端和服务器正常运行的情况下，如果网络断了，（比如说我把网络弄掉了，然后再接好）过了一会网络恢复正常，客户端能自动连接到服务器端，不能人工干涉！ 我查了一些资料，在VC里有一个函数OnTimer(nIDEvent)可以定时产生事件！可以实现这个功能，但是我用了，还是连不上，请大家帮帮忙吧！做好后给我发到我的邮箱里！谢谢！-This is a complete C/S programe,but I hope put more function into it.Please help me.Fllowing is I ll want to do.When client is communicating with server normally,the network link is down. After while the link recovery(ie,I take the cable out from the computer then plug it in.)The Client can reconnect the server automatically not redo by human.I study some reference information to do it.There is a function OnTimer(nIDEvent) in VC can send event message periodically.But I still can t reconnect.Please help me to do it and then mail to me. Thanks.

WINSOCK服务器端示例程序说明 该程序是基于对话框编程的，是采用一对多的方式进行连接的。 整个程序主要由CServerDlg,CServerApp,CListenSocket,CClientSocket构成的。 （所有关于类的说明在代码中有） 下面简单介绍一下程序流程： 主程序调用CListenSocket类的对象来进行对Socket的监听，当收到请求时调用主程序的函数来处理相应的连接，把Socket放进队列中。 对于Socket的接收数据和断开连接是由消息来触发的，是通过调用基类CSocket中的虚函数重载来处理的。 注：详细的过程，在程序代码中均有注释！-Winsock server sample program note that the procedure was based on dialog programming, using one-to-many is the way to connect. The entire process by CServerDlg, CServerApp, CListenSocket, constitute the CClientSocket. (All categories on the note in code) The following outlines procedures have : main program called CListenSocket category to the target of the listening socket, when the call request is received when the main program functions to the corresponding connections, socket into the queue. Socket for the reception of data and disconnected from the news to trigger, by calling the base class CSocket the virtual function to handle the heavy load. Note : Details of the procedure code have Notes!

这是一个找到一篇关于权限设计的教程，写的很好，但是发现给出的代码，有些地方可能有笔误。贴出来供大家和我一起学习。 ----------------------------------- 首先,设置三种要素：用户、群组、角色。 用户为登录用，对应到人。群组对应为用户的集合，是一种特殊的用户。角色为一组权限项的集合，用户（群组）都有各自的角色。 权限的实现通过Permission类和Rule类来实现。 Permission供外部调用，Rule为一个接口，为权限判断规则。 -This is a mandate to find a design of the curriculum and write well, but the code is found, in some places may be misdirected. Put up for us and I study together.----------------------------------- First, the set of three elements : user, group, role. Users login to use corresponds to the people. User groups corresponding to the pool, a special users. A role for the authority, of the group assembled users (groups) have their own role. To achieve competence through Permission Rule category and class to be achieved. Permission for external calls, as a Rule interface for the authority to judge rules.
