MFC 带有一个 CRectTracker 类. 用来画出所谓的橡皮条矩形. 但在 WTL 里面, 没有对应的类. 所以,自己写了一个非常简单的 mix-in class, 在 WTL 里面使用, 将这个类作为您的窗口的基类即可让窗口具有画橡皮条矩形的行为.上载的压缩文件包含两个源文件, RectTracker.h 即为这个 mix-in class. SnapShotWnd.h 为使用这个类的一个窗口. 还有一张屏幕抓图, 从图片可以看出这个窗口的功能, 他实现类似透明窗口的功能. 注意那个虚线框, 就是 CRectTracker 画出来的.-MFC with a CRectTracker category. To draw of the so-called rubber rectangle. The WTL, there"s no corresponding category. So they want to write a very simple mix-in class, the WTL is used to this category as your window so that the base class can be painted with rubber window the behavior of the rectangle. on the compressed file contains two sources, namely the RectTracker.h mix-in class. SnapShotWnd.h for the use of this kind of a window. Previously there a screen, pictures can be seen from the window of the function, he achieved similar functions transparent window . Note that dash is the CRectTracker painting.

用VC开发GIS系统用比较好。用VC++实现矢量地图背景下的实时显示源代码-VC with GIS development is good. With VC vector background maps show the real-time source code

通过派生的概念来组织和管理不同对象，这里我们可以绘制椭圆，矩形，圆，字体等，可以对不同对象进行控制-Through the concept of derivative to the organization and management of different objects, here we can draw an oval, rectangular, round, font, and can thus control different target groups

该程序包括了基于GDI的H.263+的qcif文件播放代码。-based on the H.263 GDI qcif player code.

用VC++编写一个圆,并使其沿正弦曲线运动,在此过程中,圆的大小不断地变化,并在左上角显示几行的不同字体的字-prepared a VC round, and it sine curve along the campaign, in the process, won the size changes constantly, and in the upper left corner shows a few lines of the different font characters

学生自己制作的c程序，中国象棋，尽管界面不是很漂亮，但是用c写到这地步已经是很不容易-produced by the students themselves c procedures, Chinese chess, although the interface is not very beautiful, But using c wrote this stage is not easy

寻找圆的程序，大家试一试！-procedures for the round, we try!

采用OpenCV的GUI函数并结合Visual C++ 的单文档进行视屏的打开与播放。-The GUI uses OpenCV function in conjunction with Visual C++ in a single document Shiping open and playback.

source目录下为本章介绍的源程序功能是腐蚀，膨胀，细化算法-source directory for the chapter describes the source function is corrosion, swelling, thinning algorithm

程序最小化后在右下角显示一个小图标的实现～-Minimization procedures in the lower right corner displays a small icon in the realization of ~
