VC (MFC)网络调试助手
新手入了MFC的坑，做MFC网络调试助手，记录：
1.效果图，下方有连接（免费）
2.网络调试助手功能较完善，不支持中文转16进制，目前没想到好方法，欢迎交流
3，socket通信使用MFC封装的CSocket类，搞清楚通信的流程很重要，这样的文章有很多
4，进制之间的转化，这个涉及到进制之间的互相转化，因该多去学习
5，各种控件的使用。
socket的通信，TCP 服务器 Create，bind ,listen ,accept, send/Receive
客户端：create ，connect ,send/Receive
这个软件 支持TCP server /TCP client /UDP 三种通信方式，设计CSocket派生类，CSocku 用于接收UDP通信的消息，CClientSocket用于接收服务器发送来的消息，CConnectSocket类接收客户端发送来的消息。在三个派生类中添加OnReceive虚消息。CnettestDlg中服务发送消息。CListenSocket中用CPtrlist存放每一个访问的客户端地址。

总之，先搭起socket通信的架子，剩下的东西再往里塞就可以了。
