本实例演示了利用DAO访问数据库的常用方法，并附带了所用的数据库course.mdb。(examples demonstrating the use of DAO Database Access commonly used methods, and the incidental use of the database course.mdb.)

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)
