制作连接数据库的实例。当程序运行之后,程序将查询当前工作目录下的名字为jdbc.mdb的数据库,然后通过jdbc-odbc桥进行数据库的连接,最后判断数据库的连接状态,并且将数据库的连接结果打印输出到屏幕显示。-production connect to the database example. When running, the procedures will be for the current working directory under the name of the database jdbc.mdb, then jdbc- odbc Bridge database connectivity, the final judgment of the state of the link database and the database will link to print out the results display.

一个增强的数据库类CDataSet 因为MFC完全支持数据库应用程序的开发,所以大多数数据库应用都使用CDatabase和CRecordset类,并且类向导(Class Wizard)提供了快速简易的方式来使用这两个类。有一点不足的就是当应用程序涉及到多表数据库时,类向导将产生大量的关于记录集的源码文件使得工程(project)给人的感觉很混乱。 本文介绍如何使用一个模板记录集类来降低类向导所产生的记录集文件的数量,同时增强记录积类(CRecordset)的功能。这个模板记录集类叫做:CDataSet。它的主要目的是降低代码量,为数据对象数组提供一个接口。-an enhanced database category CDataSet because MFC fully support database application development, the majority of database applications used CDatabase and CRecordset class and category Wizard (Class Wizard) provides a fast and easy way to use these two categories. There is one point when the shortage of applications related to multi-table database, the wizard class will have a lot of records set on the source document makes the project (project) gives the impression that very confused. This paper describes how to use a template Records Set to reduce class wizard from the record set in the volume of documentation, while enhancing the plot record category (CRecordset) function. The template called Set Records

考虑霍夫曼每个选择的是最小的两个频率(..
时考虑到在哈夫曼中要每次挑选两个频率最小(即出现次数最小,我那个hNode里的value
是出现的次数),很自然的就想到了std::priority_queue容器,优先队列每次都会弹出队列
中权值最高的元素,这个特性无疑是实现哈夫曼算法的最佳选择。 ...
-to consider the Huffman each selected to be the smallest two frequencies (that is, the minimum number, which I hNode"s value is the number of occurrences), it is natural to think of the std : : priority_queue containers, each priority queue queue will pop the top right elements, the Characteristics undoubtedly Huffman algorithm is the best choice. ...
