Visual C++语言提供了虚屏功能，利用它及Windows GDI图形函数，可编制出功能强大的图形处理程序。虚拟屏幕的原理是，首先定义一个虚拟设备描述表及一块位图象数据区，将本应在实际窗口的绘画处理转移到此图象数据区（这块图象数据区功能相当于视频存储区），绘画操作完成后可通过图象传递，将结果弹出到可视窗口。许多Windows环境的图形处理或CAD系统都采用了这种技术。如GIS软件Mapinfo、AutoCAD for Windows等，它们的图形操作功能如开窗、漫游等的基础都是建立在虚屏基础上，并且将操作界面都作成工具窗（一种特殊的窗口，客户区内规则地排列着图象按钮响应操作代码）的形式，直观、灵活且便于用户选择操作。VC++的CDC类、CBitmap类封装了对虚屏的操作，利用类的继承性，也可很容易的实现工具窗。(Visual C++ provides a virtual screen function, use it, and Windows GDI graphics functions, can be prepared in a powerful graphics program. The principle of the virtual screen, first define a virtual device description table and a bit image data area, the present should be transferred in the actual window painting processing of this image data area (this image data area function equivalent to the video memory area ), after the completion of the painting operation can be passed through the image, the results of the pop-up to the visible window. Graphics or CAD system for many Windows environment using this technology. GIS software Mapinfo, AutoCAD for Windows and other graphics operations functions such as windows, roaming the foundation are built on the basis of the virtual screen, and the operator interface made ​ ​ tool window (a special window, the client area regularly arranged in the form of image button in response to the operation code), intuitive, flexible and user-fri)

自由拼音输入法源程序,一个类似"智能ABC"输入法源代码. (Free Pinyin input method source code, a similar " smart ABC" input method source code.)

Develop class Polynomial. The internal representation of a Polynomial is an array of terms. Each term contains a coefficient and an exponent. The term 2x4 has the coefficient 2 and the exponent 4. Develop a complete class containing proper constructor and destructor functions as well as set and get functions. The class should also provide the following overloaded operator capabilities: Overload the addition operator (+) to add two Polynomials. Overload the subtraction operator (-) to subtract two Polynomials. Overload the assignment operator to assign one Polynomial to another. Overload the multiplication operator (*) to multiply two Polynomials. Overload the addition assignment operator (+=), subtraction assignment operator (-=), and multiplication assignment operator (*=).

说明：  串口通信高级编程提供了一个能够进行串口通信的类，能够方便地进行各种数据通信。 由于本程序设计到硬件编程，因此，如果读者的串口通信设备 没有连接好，可能会有问题 (Serial communication provides a high-level programming to carry out the type of serial communication, the ability to easily carry out a variety of data communications. Since the hardware design to programming, so if the reader' s serial communications equipment is not connected well, there may be some problems)
