字典序问题:在数据加密和数据压缩中常需要对特殊的字符串进行数字编号。给定的字母表 A 由 26
个小写英文字母组成 A={a,b,…,z}。该字母表产生的升序字符串是指字符串中字母按照从左
到右出现的次序与字母在字母表中出现的次序相同,且每个字符最多出现1 次。例如,
a,b,ab,bc,xyz等字符串都是升序字符串。现在对字母表A 产生的升序字符串按照字典序排列

DataGridViewAutoFilter
The Microsoft® Windows Forms DataGridView control in
Microsoft® Visual Studio® 2005 provides a grid experience similar to Microsoft®
Excel, but does not provide the column filtering drop-down lists that Excel
provides in its AutoFilter feature. However, the DataGridView can bind to data sources that provide
filtering, such as the ADO.NET DataView. This article describes how to build a custom DataGridView column header cell
that displays drop-down filter lists, by taking advantage of the filtering
capabilities of the data source and the new BindingSource component.
