这是OLE DB的一个完整例子，演示了COM下怎样从数据库读取数据。(This is a complete example of OLE DB, demonstrates how to read the data under the COM)

一个元器件管理的管理软件。主要体现在对数据增删改查方面，即对数据库的操作。使用的是ACCESS数据库，ADO方式连接。程序启动时弹出登陆界面。用户名admin，密码123456。不同的用户登陆之后界面也不一样。(An Element Manager System，Use Access Database for add,delete,update and query data.Use ado type connect Database.You can use user:admin,password:123456 login in.and different user have different functions.)

奶牛健康管理系统！MFC界面，实现奶牛资料的录入、删除、更改、查询等操作!还有奶牛所属农场主的信息！可以输出资料到excel中！连接Access数据库！(Dairy Health Management System! MFC interface, data input to achieve cows, delete, change, query and other operations! There is information on dairy farmer-owned! Can export data to excel in! Connect Access Database!)

处于不同目的的旅客对交通工具有不同的要求。编制一个全国城市间的交通咨询程序，为旅客提供两种或三种最优决策的交通咨询。(Different purposes in the mode of transport of passengers have different requirements. The preparation of a national inter-city traffic advisory procedures, provide passengers with two or three optimal decision of the Transport Advisory.)

数据库监视备份软件客户端通信软件广播状态参数 当前的主库(DWORD)+当前的状态(DWORD) (Database to monitor the backup software client software radio communication parameters the current state of the main library (DWORD)+ Current status (DWORD))

Monkeys and peach,Monkeys and peach(Monkeys and peach)

mfc下封装的一个数据库类，用ado方式调用access数据库(a class of encapsulates the database, call the access database using ado way)

这是我在学习数据结构做练习时写的一个小程序，功能是在命令行下进行形如：23+34*3/4+(3*6+10)的四则运算，支持+,-,*,/,(,)进行整数运算。(This is a simple code about data structure.It uses to carry on four arithmetic operations with parenthesis.But now it only supports integer.)

说明：  了简化开发人员编写数据库应用程序，VC++的在其基础类库（MFC）里对ODBC API进行了封装，实现了一个面向对象的数据库编程接口，使VC++的数据库变得更加容易。 本章首先对MFC ODBC的概貌进行简要介绍，然后讲述利用MFC ODBC进行数据库开发的技巧，最后将通过具体数据库开发实例，详细讲述通过MFC ODBC开发数据库应用程序的方法和过程。(Simplify developers to write database applications, VC++ Class Library in its base (MFC) in the package on the ODBC API to achieve an object-oriented database programming interface, so that VC++ database easier. This chapter begins with an overview of the MFC ODBC brief introduction, then tell a story using MFC ODBC database development skills, and finally database development through specific examples, describe in detail through the MFC ODBC database application development methods and processes. )

使用三叉链表实现的哈夫曼树,统计inputfile1.txt中各字符的出现频率，并据此构造Huffman树，编制Huffman 码；根据已经得到的编码，对01形式的编码段进行译码。 具体的要求： 1．将给定字符文件编码，生成编码，输出每个字符出现的次数和编码； 2．将给定编码文件译码，生成字符，输出编码及其对应字符。 (Emergence of the frequency of each character in the trigeminal lists using the Huffman tree, statistics inputfile1.txt, and accordingly the Huffman tree structure, preparation of Huffman code according to the coding has been. 01 to form the code segment for decoding. Specific requirements: 1 coding the given character file, generating the encoding, and outputting the number and encoding of each character 2 will be given the encoding file decoding, generating the character, the output code and its corresponding character.)
