//    I finally came up with a really smart way to maintain ini file.
//    Every time I add a variable to CAppConfig, all I need to do is 
//    adding the variable in my "Config Table," and all the data will
//    be load and save automatically.  This is not the most efficient way. 
//    In my first version I use some more efficient method, but at last I change 
//    my code to what it is now.  Because I think in a program not time-critical,
//    easy-maintaining is much more important.
