UDP 接收数据类，里面有个接收UDP数据的线程。 我自己使用的，可靠的，已经编成DLL了，其中有些解析二进制流的代码，可以不看。(udp socket program , focus on recieve udp data.)

通过分析比较3种聚焦效果较好的清晰度评价函数，提出了一种基于聚焦窗口模式的平方梯度函数作为聚焦评价函数，建立了评价函数的数学模型，并给出了实验分析和结果。与以往常用的评价函数相比，具有更高的可靠性和聚焦灵敏度(Compared by analyzing the three kinds of focus better clarity evaluation function, a model based on the focus window as a function of the square gradient focusing evaluation function, the establishment of the evaluation function of the mathematical model, and gives the experimental analysis and results. Commonly used in previous evaluation function, compared with higher reliability and sensitivity Highlights)

VC++ 使用MFC ODBC访问数据库，请注意：在VC环境下运行程序前，必须注册ODBC数据源，数据库文件为bookinfo.mdb，数据源名称为bookinfo，直接运行可执行文件也需要将数据库文件与可执行文件放在同一路径下(VC++ using MFC ODBC to access the database, please note: In the VC environment before running the program, you must register ODBC data source, the database file is bookinfo.mdb, data source name is bookinfo, also need to run an executable file with an executable database files files in the same path)

MapViewer是利用Visual C++ 6.0对MapX组件进行二次开发得到的一款小型软件。它能实现GIS软件的一些基本操作，包括地图数据的输入、输出、空间查询检索、专题图的制作等 (MapViewer are using Visual C++ 6.0 on MapX components received by the secondary development of a small software. GIS software, it can achieve some of the basic operations, including the map data input and output, spatial query retrieval, thematic map production, etc.)

一个文本搜索的console程序,可以从一个txt文本文件中查找数据 不错的(A text search console procedures, can look for data a TXT text file)

内存映射文件的使用(The example of using memory map file)

For introductory programming class, simple logic coding.

说明：  管理windows的网络进程程序 可以实现进程的建立，端口号，关闭的功能，隐藏的也可看到(serveices management for windows)

基于SOCKET编程，模拟聊天窗口，可选择端口号等，两个窗口之间可以相互发送信息。(SOCKET-based programming, simulation of the chat window, two windows to send messages between each other.)

实例321——利用MSComm控件进行串口通信(Examples 321 use MSComm control serial communication)
