[OS program] 5 DL : 0: 阿拉伯数字转为大写汉字的类本人写了一个一个将阿拉伯数字转为大写汉字的类，主要使用了stl中的string类，该类使用方便，还可以自动识别过滤夹杂在阿拉伯数字的逗号，空格等，符合日常习惯中的用法，程序在附件中请检验，使用方法就是main函数中的方法，请检验。如蒙不弃请笑纳。 -Arabic characters into upper class I wrote a one will be converted to uppercase characters Arabic classes, the main use of stl in the string class, the class easy to use, you can also automatically identify filtered mixture of Arabic comma in the air grid and so on, in line with everyday usage habits, the program in the annex, please test main function is to use the method, please test. Please kindly consider it if not abandoned.

[OS program] SimpleXML DL : 0: 简化的XML处理类，能得到XML中元素的值，使用简单。使用方法：将XML字符串传给本类实例即可，如下所示(Result为XML字符串，可从文件中读出）。 Dim XML As New SimpleXML Dim strName as string XML.Content = Result strName = XML.GetTag("Name") -Simplify XML processing class, to get the values of the elements in the XML, and simple to use. Usage: XML string passed to the class instance you can, as shown below (Result as an XML string, can be read from the file out). Dim XML As New SimpleXML Dim strName as string XML.Content = Result strName = XML.GetTag (" Name" )
