(转载)这篇文章是我的一些工作结果
(转载) 这篇文章是我最近的一项工程中做的一些工作的结果。我正在改良一个复杂的主从式用户应用,他用到了好几个数据库。它们的共性是DSN(数据源名)的使用。因为用户发现查在控制面板中用ODBC结构工具查找出DSN很不方便,因此我们决定为DSN做一个浏览按钮。 来源: http://www.codeguru.com/mfc_database/DSNCollection.shtml- (reprint) this article is some work results which in an my
recent project does. I am improving a complex host from the type user
application, he used the quite several databases. Their general
character are DSN (data source name) use. Because the user discovered
looks up searches DSN in the control panel with the ODBC structure
tool not to be very convenient, therefore we decided is DSN makes a
browsing button. Origin:

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. ...
