/*****************************************************************文件名:读取当前目录下CIniFile类文件
日期:2004-1-18 作者:chao_jie E_Mail:chaojie2003@yahoo.com.cn功能:系统提供的WriteProfileInt()等函数，写到注册表或
系统ini文件里，调用比较麻烦，而且会占用注册表资 源，下载了网上的ini类用起来又不太顺手，所以参照 写了一个读取当前目录下ini文件的类。程序有详细的 注释，欢迎批评指正。*****************************************************************/
/*//
使用方法: 1.先把IniFile.h，IniFile.ccp加入Porject，在要使用该类的头文件中加入 #include "IniFile.h"，及CIniFile IniFile;2.读取和写入:
string = IniFile.GetString("section","item","默认"); int = IniFile.GetInt("section","item",666);IniFile.SetString("section","item","设置值");
IniFile.SetInt("section","item",666);3.ini文件名及路径在初始化时，用SetFileName()设置
注意事项:ini文件如果太长，读取速度会变慢，可以使用多个ini文件
