说明：  vc++开发的屏幕编辑工具，已编译调试通过(vc development of the screen editing tools, compiled through debugging.)

这个是华为的VoIP文档，讲述清晰，值得阅读！(This is Huawei' s VoIP documents, about clarity, it is worth reading!)

在程序中嵌入日历，是一本书中找到的很有学习的价值(Embed calendar program is useful to learn the value ，found in a book)

178个经典c语言源代码+算法大全 还有经典C程序100例 学习程序设计的很好的参考(178 classic c language source code+ algorithm Daquan There are 100 cases of classic C program Good reference for learning program design)

虚拟摄像头 directshow技术 采用gdi+截取位图(this is a Virtual Camera，mey be help you)

复杂环境下无人机的路径规划，用rrt和a*算法实现，在qt开发环境下编译。(Complex environment UAV path planning with rrt and a* algorithm, compiled under qt development environment.)

但是对于“真二叉树”（每个内部节点都有两个孩子的二叉树），给定它的先序、后序遍历序列足以完全确定它的结构。将二叉树的n个节点用[1, n]内的整数进行编号，输入一棵真二叉树的先序、后序遍历序列，请输出它的中序遍历序列。(But for one proper binary tree, in which each internal node has two sons, we can uniquely determine it through its given preorder traversal sequence and postorder traversal sequence.Label n nodes in one binary tree using the integers in [1, n], we would like to output the inorder traversal sequence of a binary tree through its preorder and postorder traversal sequence.)

window下注册一个虚拟摄像头，并且在内存中开辟一块共享内存，将共享内存中的数据显示在摄像头中。qq等聊天工具可用。(Window registered a virtual camera, and in memory to open a shared memory, the shared memory data display in the camera. QQ chat tools available.)

透過 Socket 擷取影像，並進行 OpenCV MOG2 計算(Capture images through Socket, and OpenCV MOG2 computing)

说明：  时间控制,可以自己随意得控制自己的时间，把时间任意延长(time control, it has to control their own free time, the arbitrary extension of the time)
