//	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.
