wince 基础技能使用ini配置文件来保存信息

今天和大家分享最近用到的一个基础技能：ini文件的使用

最近的项目arm没有外接eeprom，运行过程中应用程序开开关关数据的保存是个问题

所以用最常见的方式ini文件。

最开始我把ini文件存在nand flash中，但是后来发现使用的nand的擦写次数仅有10000次

于是就把ini放置在内存文件夹中

下面具体展示下代码

首先是封装好的代码不是我写的，是网上收集的，这个算是写的不错的：

需要注意的是，这样的保存并不适用与断电，因为是在内存文件夹

所以断电的话，我会把所有数据发送到MCU的eeprom，上电首先MCU会发给arm初始化信息

呵呵！算是给和我一样的新人一个提醒，不要随便擦写，特别是nand flash

文中并么有详细讲解代码，大家有何指教或疑问留言，我会一一回复的！共同进步！！！
