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.
