清华大学数据结构课上实现的B+树，设计一个4阶B+树，包括： (1) 叶子的每个记录应该包括4字节（long）关键码值和60字节的数据字段(存储文件名等，可以自定)，设每个叶子可以存储5条记录，而内部节点应该是关键码值/指针对。此外，每个节点还应该有指向同层下一个节点的指针、本节点存储的关键码数等； (2) 此4阶B+树应该支持插入、删除以及根据给定关键码值进行精确检索与关键码范围检索； (3) 显示（打印）此4阶B+树的生长(含删除节点)过程实例；-Tsinghua University class data structure to achieve the B-tree, the design of a B-tree four bands, including : (a) the leaves of each record should include 4-byte (long) key code value and 60 gigabytes of data fields (document storage, etc., can be set), set up each leaf store five records, and internal nodes is the key code value/means against. In addition, each node should have the same point under a layer of the target node, the node storage key code number; (2) The B-tree four bands should support the insertion, deletion and with the given key code value accurate retrieval and key codes scope retrieval; (3) Display (Print ) This four bands B-tree growth (including the deletion of nodes) process examples;

使用VBA可以将SQLServer数据库生成数据库，用word宏实现的数据字典生成器。 打开word文档后，按alt+f11即可看到源码。 需要修改其中的数据库连接串，否则无法连接数据库成功，也无法生成数据字典。 按F5即可运行查看生成的数据字典。 目前只支持SQL Server，不支持其他数据库

本程序使用Visual C++6.0编写，使用了MFC，数据库用的是SQL Server，要正常运行本程序，请安装该数据库，并参看压缩文件中的DBConfig.ini文件。本程序如果和已经上传的NetControlManager已经完全可以满足用户对局域网控制的需求，特色功能包括：登陆认证、局域网内特定IP上网限制等-This procedure using Visual C++ 6.0 preparation, the use of the MFC, the database used is SQL Server, to the normal operation of this program, please install the database and see the compressed file in the document DBConfig.ini. This procedure has been uploaded If NetControlManager has been fully able to meet user demand for LAN control, features include: login authentication, LAN specific IP access restrictions

一个自己定义的数组外包装，这是“使用者自定义stl容器“的一个好例子，在数组之外包装了一层常用的容器界面。-own definition of an array overpack, which is a "user-defined stl containers" of a good example In addition to the array of packaging containers used layer interface.

网友 lc_mtt (网名：柠檬) 提供的一个比较完善的超市销售管理系统（后台)，漂亮的Office XP界面，功能基本完善，基于MS SQL Server 2000后台数据库开发，作者自主独立开发，对于想学习SQL Server数据库开发的网友是一个很不错的范例。有关具体信息请参见压缩包里的运行说明书。-Netizen lc_mtt (Network Name : Lemon) to provide a more complete Supermarket sales management system (background) pretty Office XP interface, improved basic functions, Based on the MS SQL Server 2000 database development background, the authors developed independently, For want to learn SQL Server database development in the discussion is a very good example. The specific information please refer to a bundle of the compression operation manuals.
