使用RAD类型工具的人越来越多了，虽然我对于RAD类的工具向来不多作评议，但我还是常常使用的。所以我深深的知道这类工具虽然给我们带来了便利，使我们能不用将更多的精力放在界面上，但同时也将初学者紧紧的圈在了他所提供的控件和组件中。所以很多人并不能真正的了解windows的消息驱动原理以及windows的运作过程。本文中我们就一起来学习一下windows的运作过程，使我们对delphi这样一个优秀的编程工具有一个新的认识，并对windows下的程序编写有更深刻、透辟的了解和认识。-RAD type of tool used more and more people, although I have RAD tools have always been small for the council, but I often use. Therefore, I deeply know that although such tools has brought us convenience, so that we can not put more focus on the interface, but at the same time will also be closely beginners circle in which he controls and components provided by in. Therefore, many people can not really understand the windows of the message-driven principle as well as the operation of windows. In this article we will work together to learn about the operation of windows, so we have such a good delphi programming tools have a new understanding of, and under windows programmers have more profound and thorough understanding and knowledge.

摘要：报告描述了在同组人员吴玉成同学完成学籍管理系统的后台数据库开发的基础上，本人用visual basic完成前台开发过程及其代码。在开发后台数据库的时候，是严格按照软件工程原理的方法做的。但是考虑到本人对开发工具vb不是很熟，所以在前台设计的时候也只是完成了部分的功能。我们把重点都放在数据库的后台设计开发上。对整个数据库做了详细的分析设计。这部分的报告在同组人员吴玉成的报告中。我的报告不再重复。Vb虽然有很多方法和数据库建立连接，也有很多控件可以直接对数据库的数据进行操控，但是为了实现一些有意义的功能，而不是简单的上一条记录下一条记录等查看。与ADO数据访问控件不同，ADO操作数据主要使用程序代码。通过代码创建对象，与数据源连接，执行命令等。 关键字：与sql server 2000建立连接；vb实现 -Abstract : report describes the same team WU Yu-cheng students Maintenance Management System completed the background database development on the basis of I use visual basic completion of the development process and its prospects code. Background in the development of the database, is in strict accordance with the principles of software engineering methods do. However, considering that my right development tools vb is not perfectly so in the future design of the only completed part of the function. We have to focus on the background of database design and development on. Of the entire database as a detailed analysis of the desi

哲学家进餐问题是荷兰学者Dijkstra 提出的经典问题之一,它是一个信号量机制问题的应用,在操作系统文化史上具有非常重要的地位。对该问题的剖析有助于学生深刻地理解计算机系统中的资源共享、进程同步、死锁等问题,并能熟练地应用信号量来解决生活中的控制流程,即将生活中的控制流程用形式化的方式表达出来。 假设有5个哲学家，他们花费一生中的时光思考和吃饭。这些哲学家共用一个圆桌，每个哲学家都有一把椅子。在桌子中央是一碗通心面，在桌子上放着5只筷子。（如图所示）当一个哲学家思考时，他与其他同事不交互。时而，哲学家会感到饥饿，并试图拿起与他相近的两只筷子（他与邻近左、右之间的筷子）。一个哲学家一次只能拿起一只筷子。显然，他不能从其他哲学家手里拿走筷子。当一个饥饿的哲学家同时有两只筷子时，他就不能不用释放他的筷子而自己吃了。当吃完后，他会放下两只筷子，并再次开始思考。 规定奇数号哲学家先拿他左边的筷子，然后再去拿右边的筷子；而偶数号哲学家则相反。按此规定，将是1、 2号哲学家竞争1号筷子；3、4号哲学家竞争3号筷子。即五位哲学家都先竞争奇数号筷子，获得后，再去竞争偶数号筷子，最后总会有一位哲学家能获得两只筷子而进餐。 -dining philosophers problem is the Netherlands scholars Dijkstra"s one of the classic, It is a signal to the mechanism of application, the operating system in the history of culture has a very important position. Analysis of the problem to help students understand deeply the computer system resource sharing, process synchronization, and other issues Deadlock, skilled and can be applied to solve the signal volume life of the control flow, about the life of the control flow wi
