一个目录变化监控类，空闲时间写的，方便调用，可扩展(A directory change monitoring class, free time to write, easy call, scalable)

编程环境为Visual studio2008，采用dxflib库编写，内部定义了一些图形类，可以实现dxf文件的读取，显示，及删除操作。页面侧边有动态标尺，按住鼠标中键可平移窗口，拨动滚轮可缩放视图，采用窗口裁剪以及显示缓存来提高性能及防止闪烁。本来是做为激光切割机控制系统来开发的，但是后来因为某些原因搁浅了，现在就拿出来供大家参数吧。界面上有一些激光加工参数的输入，但是实际是没有任何作用的。 程序界面使用wxwidgets库编写。这是一个跨平台的库，有很多有用的控件，在不同平台是会有相应平台的风格。此程序也可做为学习wxwidgets的例程。 编译此程序需要wxwidgets2.8.7　；这是一个开源的界面库，请到官方主页去下载。 本人英文不好，以下英文描述为自动翻译。请见谅(Programming environment for Visual studio2008, using dxflib library prepared a number of graphics within the definition of class, can achieve dxf file to read, display, and delete operations. Pages are dynamically scale the side, hold down the mouse button to pan the window, toggle wheel to zoom the view, with window clipping and display cache to improve performance and prevent blinking. Originally as a laser cutting machine control system to develop, but was stranded for some reason, and now Take it out for your parameters. Interface, there are some laser processing parameters input, but actually have no effect. Prepared using the wxwidgets library program interface. This is a cross-platform library, there are many useful controls, there will be appropriate in different platforms, platform style. This procedure can also be used as learning wxwidgets routines. Compile this program requires wxwidgets2.8.7 this is an open source interface library, please go to the official home page)

vc++ 开发的opc客户端的例子程序。基于文本界面，合适二次开发用。(opc server example.)

程序分2部分，一部分是用C++编写，负责显示3D效果，另一部分是由C#编写，负责网络通信(Program in 2 parts, one written with C++, responsible for displaying the 3D effect, the other is written by the C# is responsible for network communication)

基于ffmpeg+sdl的视频播放器，直接部署工程然后，设置本地视频路径就可以播放视频。(Based on ffmpeg+ sdl video player, direct deployment project then set the local video path can play video.)

这是一个介绍vc 和matlab混合接口编程的实例，主要是在vc下面调用matlab里的各个库。(This is a example of introducing vc and matlab programing , it call matlab s function in visual C++.)

编辑MFC界面，打开txt数据文件，读取文件，显示文件里数据的行数。(Edit MFC interface, open the txt data files, read the file, display the number of rows in the data file.)
