MFC 画图程序 包括了所有画图的功能！ 里面包括了源代码，相当好用！(MFC Paint program to include all the functions of drawing! Which includes source code, very easy to use!)

说明：  双DSP与FPGA的发电机控制器的设计Dual DSP and FPGA design generator controller(Dual DSP and FPGA design generator controller)

基于supermap的二次开发，数据管理功能强大，除了地图的基本操作还有文件操作(Data Management is a powerful addition to the basic operation of the map file operations based on the secondary development of supermap)

E:Visual_C__MFC扩展编程实例 例18 动态地抓取应用程序的屏幕图像并将其打印。 上一个实例打印的是文档的报表，而不是当前出现在屏幕上的内容。在本例中，将实现 屏幕抓取并打印其内容。M F C 为打印视提供了有限的支持， 但只要用M F C 在 C Vi e w : : O n D r a w ( )中所提供的设备环境，就可以绘制自己的视。在打印视的时候， M F C只需调 用具备打印机设备环境的O n D r a w ( )函数即可。但是，如果不绘制自己的视，例如，用一个或 者一个以上的控件窗口填充自己的视就不会打印任何东西。每个控件将使用自己的设备环境 将自己打印到屏幕，因此打印视的唯一途径就是抓取屏幕(拷贝其内容到一个位图对象)并将其 打印到打印机。由于该功能整个与位图相关，因此将该功能封装到了位图类中。(E : Visual_C__MFC expand programming examples cases 18 crawls dynamic application's screen images and their Print. Print example, a document is a statement, rather than the current appeared on the screen content. In this case, to achieve the screen crawls and print its contents. M F C Print, as provided limited support, but as long as M F C in C Vi e w : : O r a n D. w (), which provided the equipment environment, we can draw our own consideration. In Print, as when M F C only with the printer device called the environment O D r a n w () function can be. However, if we do not draw their attention, for example, or one with a control over their windows filled as it will not print anything. Controls will use their own equipment to their environment to Print Screen, Therefore, as Print i)

根据3dmax导出的obj格式，将 txt文件的内容以 obj的格式储存，然后在3dmax显示。首先 读入txt文件的内容，然后依次写入obj文件里面
