vb6中一个非常好用的读写ini文件的模块
hejianzhong
网上读写ini文件的例子只有几篇相同的文章，而并不好用，奇怪的是各网站都是同样的例程，高手也就罢了，三下五除二就搞定，初学者会被搞得一头雾水，看着一个好好的模块就是不能用。
所以我整理了一下（最早是在腾讯答一个贴子时写的），这个也就是修改了一下，不是我自已的发明(至于这个代码起先不知是谁写的),不过非常的好用
新建模块（建议不使用注册表） 命名为rwini
'ini文件在有回车换行符会出错，经过测试，汉字要小于86字节，英言文要小于143字节才能返回列表框。（这是我以前的code，是记录列表框内容的）

public declare function writeprivateprofilestring lib "kernel32" alias "writeprivateprofilestringa" (byval lpapplicationname as string, byval lpkeyname as any, byval lpstring as any, byval lpfilename as string) as long
