定义Matrix矩阵类，定义矩阵类头文件matrix.h(Matrix matrix class definition, define matrix class header file matrix.h)

用VC++实现数据库中图片的存取与显示精讲教程，如何将图片存储在数据库中，又如何从数据库中读取出图片并显示。教程主要介绍了在VC ++环境中,利用ADO 2. 5中所提供的Stream对象和Fields对象进行数据库中图片的存取,同时还利用了IPicture接口实现多种格式图片的显示,并通过控件自画的方法解决了图片显示的刷新问题。 (VC++ image access and display)

使用ODBC访问数据库，一则ODBC是直接封装在MFC库里面的，二则忙着考研没有时间学习dao。 ODBC和DAO用起来可能最大的区别就是ODBC使用之前得先建立数据源，根据不同的数据库，使用的参数也不同。具体请看在这之前的一片文章。里面有许多东西没有说，属于高级技巧性东西，得学你们自己摸索。(Using ODBC to access the database, an ODBC database directly encapsulated in the MFC inside, two busy Kaoyan no time to learn dao. ODBC and DAO can be at the biggest difference is that must be built before using ODBC data source, depending on the database, the parameters used are also different. Details, please read an article before this. There are many things not said, things are high skill, have to learn your own. )

一个简单的火车票查询系统，也可以维护数据库。使用VC6.0开发，MFC框架，Access数据库，ADO连接方式。(A simple ticket query system, you can also maintain the Database. Use VC6.0 development, MFC framework, Access databases, ADO connections.)

使用ADO导出数据,在数据库编程中应用很多。(Use ADO export data, many applications in database programming.)

轻型数据库,适用于嵌入式软件开发。占用系统资源少。(small ，be fit for embeded software developement. )

该代码包括了队列的实现，主要包括队列的进出问题， 以及队列的查询，删除等问题。(The code includes queue implementation, mainly including queue in and out of the question, as well as the queue query, delete, etc.)

数据库开发的ado连接，包括存入图像，读取图像的方法，值得入门的学习下(Ado connection database development, including into the image, read the image, it is worth to study the entry)

实现的数据库io缓存模拟程序，读入五万个地址和读写标志，输出命中率，io次数等(Io caching implemented simulation program that reads fifty thousand addresses and write flag output hits, io number, etc.)

软件界面友好，包含了进销存的基本功能，可在此基础上进一步开发。 (Friendly software interface, contains the basic functions Invoicing can be further developed on this basis.)
