（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:

电子表格的输入和输出往往需要解决的问题。手术费。
Excel表格是输入输出经常需要涉及到的。操作Excel表格的方式也多种多样。比如，通过调用Excel程序的COM组件对Excel进行操作。但是，这种方式限制较多，且实现难度比较大。但是，用于访问数据库的组件ADO，是支持多种数据源的，其中就包括Excel文件。我们可以通过ADO组件对Excel文件进行读写访问。当然，在.NET平台上对应ADO数据访问组件的是ADO.NET组件。我编写的这个类就是通过ADO.NET实现了Excel文件的读写。由于时间仓促，功能还不是很完善，会在以后有时间的时候进行版本升级。也请各位高手多多批评指正。-Excel spreadsheet input and output is often of the need to address. Operation Excel variety of ways. For example, by calling the Excel COM procedures for the operation of Excel. However, this approach is more limited and more difficult to achieve. However, for access to the database components ADO, is to support multiple data sources, including Excel file. We can ADO components to read and write Excel files visit. Of course,.NET platform counterparts ADO data access components of ADO.NET components. I prepared this category is achieved through ADO.NET read and write Excel files. Because time is so short, the function is still not perfect, will in future have the time for version upgrades. Members also criticized many exp

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. ...
