可编程中断控制器中断控制器8259A是专门为控制优先级中断而设计开发的芯片。它将中断源优先排队、辨别中断源以及提供中断矢量的电路集于一片中。因此无需附加任何电路，只需对8259A进行编程，就可以管理8级中断，并选择优先模式和中断请求方式，即中断结构可以由用户编程来设定。同时，在不需要增加其他电路的情况下，通过多片8259A的级连，能构成多达64级的矢量中断系统-Programmable Interrupt Controller Interrupt Controller 8259A is designed for control and priority interrupt the core design and development tablets. It will interrupt source priority queuing, identifying the source of disruption and the provision of the circuit interrupt vector set in a Chinese. Thus there is no need for any additional circuit, just right for 8259 A programming, it can manage eight interruption, and to choose the mode and priority interrupt request means that the structure can be interrupted by the user to set programming. At the same time, no additional circuit of the other, through more than 8,259 tablets of class A connected, could constitute up to 64 Vector Interrupt System

本文需要你事先了解面向对象的基于消息驱动的 Windows 消息编程，当然，对于编写这个计算器，你不必知道太多的windows编程，你重要会编写基于对话框的简单应用程序就可以了。　　首先，让我们来仔细了解一下mircosoft的计算器吧，我们发现它是一个基于对话框的含有两的主对话框、一个关于对话框、一个菜单的应用程序。也就是说，我们应该创建一个基于对话框的应用程序，并且为其添加一个菜单和一个主对话框（因为，应用程序已经创建好了一个主对话框和关于对话框）。 -paper you need to advance understanding of the object-oriented message-driven programming Windows news, of course, For the preparation of this calculator, you do not need to know too many windows programming, You will be important to prepare a simple dialog-based applications on it. First of all, let us know in detail what the calculator mircosoft bar, We found that it is based on a dialog box containing two of the main dialog, a dialog on, a menu of applications. In other words, we should create a dialog-based applications, and for adding a main menu and a dialog box (because, Application procedures have been well-established and one of the main dialog box).
