虽然MSDN推荐使用注册表代替ini文件来保存程序配置和运行信息，但一般的小程序还是用ini文件来保存信息比较方便一些。

微软提供了GetPrivateProfile和WritePrivateProfile开头的一组函数来读取和保存ini文件。 比如对于名称为scan.ini的配置文件

[lastest]
year =2011
month =11
day =8
hour =19
minute =0
second =56

读取时间信息的代码如下

CTime get_last_time()
{
    int year,month,day,hour,minute,second;

    year   = GetPrivateProfileInt("lastest","year",1970,"./scan.ini");
    month  = GetPrivateProfileInt("lastest","month",1,"./scan.ini");
    day    = GetPrivateProfileInt("lastest","day",2,"./scan.ini");
    hour   = GetPrivateProfileInt("lastest","hour",0,"./scan.ini");
    minute = GetPrivateProfileInt("lastest","minute",0,"./scan.ini");
    second = GetPrivateProfileInt("lastest","second",0,"./scan.ini");

    return CTime(year,month,day,hour,minute,second);
}

写入时间信息的代码如下

bool set_latest_time(const CTime &latest)
{
    BOOL year,month,day,hour,minute,second;

    year   = WritePrivateProfileString("lastest","year",latest.Format("%Y"),"./scan.ini");
    month  = WritePrivateProfileString("lastest","month",latest.Format("%#m"),"./scan.ini");
    day    = WritePrivateProfileString("lastest","day",latest.Format("%#d"),"./scan.ini");
    hour   = WritePrivateProfileString("lastest","hour",latest.Format("%#H"),"./scan.ini");
    minute = WritePrivateProfileString("lastest","minute",latest.Format("%#M"),"./scan.ini");
    second = WritePrivateProfileString("lastest","second",latest.Format("%#S"),"./scan.ini");

    return year && month && day && hour && minute && second;
}
THE END
