该程序通过BP算法实现0-9的数字识别，识别效果比较好。(The program through the BP algorithm to identify the number of 0-9, identification of better results.)

使用vc中的socket类实现的UDP通信程序源码(Using multi-threaded approach to achieve the source code of the UDP traffic)

说明：  务器端基于select I/O模型。为防止程序界面阻塞，有一个子线程用于不断接收socket并select其中的处理。客户端只有一个线程函数，不过其利用率很高，可用于远程目录交换，请求文件大小，创建若干线程来下载文件。文件传输有上传和下载,还有对等传输，这个项目中，传输文件具体指下载。(Client server based on select I/O model. Programming interfaces in order to prevent obstruction, there is a sub-thread for receiving socket and select which treatment. There is only one client thread function, but its utilization very high, can be used for remote directory exchange, request the file size, create a number of threads to download the file. File transfer are uploading and downloading, as well as peer-to-peer transmission, this project, the specific means to transfer files to download.)

11.13 VC2003 编译 如何获得网上邻居(11.13 How to get the Network Neighborhood)

用于点云表面重建，基于Poisson重建算法，生成.ply文件，需要先求取点云法向量。(For point cloud surface reconstruction, reconstruction algorithm based on Poisson generate. Ply files, you need to strike a point cloud normal vector.)

材料力学课程的作业,用于惯性矩的计算,但也是我平时学VB的积累,(The homework in the mechanics of materials course is used for the calculation of moment of inertia, but it is also the accumulation of VB in my usual study.)

一个完善的升级程序，可供编写自动升级程序模块参考。(A complete update program solution.)

捕获局域网内的数据包，并从中的到数据，和相关信息，没开线程，我vc初学，欢迎朋友对它改进，别忘发我一份fecon@tom.com，用winpcap捕获.先安装winpcap3.1，注意改一下opnion里的lib路径(capture the data packets to and from the data, and related information, not open threads, I vc beginners welcome friends to improve it, do not forget that I made a fecon@tom.com with winpcap capture. Install winpcap3.1, to change it's lib opnion Path)

通过网络编程采集数据并实时在界面上显示，集成了自己编写的类。(Through data collection and real-time network programming displayed on the interface that integrates their preparation classes.)
