学编程还是得理论过关，才能写出好的程序。 这里有学c++的经典文章，是我在学习总结出的。里面还有许多c语言大师的好哦！将陆续与大家见面。-school programming theory still have to cross the border in order to write good procedures. Here is a classic study c article, I summarized in the study. There is also the master of many c of weeks ago! And we will continue to meet.

This article is based in part on Bob Place s ADO is AOK (a simple ADO tutorial). Wrapper Usage This is consist of 2 classes. CDyndb : This Class manages connections and recordsets. Recordsets are organized as linked list (CList) and you can access them using their ids. CDynRec : This class is the node to populate for each recordsets. ADO封装器类 这篇文章一部分基于Bob Place的《ADO is AOK》 (简单的ADO指导) 。 包裹的用法 由2个类组成。 类CDyndb: 这个类别管理连接和记录集。记录集是连接起来的记录的集合，你可以通过他们的ID访问他们。 类CDynRec: 这个类别存放记录集的代码。-This article is based in part on Bob Place s ADO is AOK (a simple ADO tutorial).

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
