IPE打包机，可以讲IP流的数据包打包成TS流数据包(IPE balers, you can speak IP flow data is packaged into a TS stream packet)

CharSample的VS2019工程版本，经过了整理和调试，包含了代码、工具、实验截图。(A full VS2019 solution for the CharSample driver, which include code, tool and the screenshot for the experiment. The code provided is tested.)

说明：  VC++ 中实现对多画面窗口的控制，基于MDI的MFC程序，用四个按钮控件控制四个文档窗口的显示(VC++ to implement multi-screen window, control, the MFC-based MDI program, with four button controls for four of the document window display)

自动打开关闭CD机舱门,方便使用，值得一试试看(Turn off automatically open the CD drive door)

关于WSAEventselect模型的使用，这个模型和WSAAsyncselect很相像，但是使用方法还是要注意(About WSAEventselect model used is very similar to the model and WSAAsyncselect, but still have to pay attention to use)

支持电力规约645，376.1等相关规约的485代码，支持常用电表控制信令代码，(Support the power of the Statute 645,376.1 Statute 485 and other related code, support for common control signaling code meter,)

C++经典语法与应用，类的编写与应用，构造与析构函数，函数的重载，类的继承，函数覆盖，基类与派生类的构造函数、析构函数先后调用顺序，如何在派生类构造函数中向基类的构造函数传递参数，this成员变量，类型转换的内幕，虚拟函数与多态性,引用和指针的变量的区别与共同处。VC工程的编译原理与过程，将工程中不同的类拆分到不同的原文件中，每一个类由一个.h和.cpp文件共同完成，头文件重复定义问题的解决，培养了学员良好的编程习惯，也为以后分析MFC Appwizard生成的工程奠定了良好基础。(Classical syntax and application of C++, class preparation and application of the constructor and destructor, function overloading, class inheritance, function coverage, the base class and the derived class constructor, destructor has invoked the order, how in the derived class The parameters passed to the constructor of the base class constructor, the this member variable of the insider type conversion, virtual functions and polymorphism, difference between reference and pointer variables in common. VC compiler theory and engineering process, the different classes in the project is split into the original file, and each class by one. H. Cpp file jointly, header files define the solution of the problem is repeated, cultivate good students programming habits, but also laid a good foundation for later analysis the MFC Appwizard generated engineering.)
