c、C++的字符处理及相互转换的技巧

// DirectoryString.h: interface for the CDirectoryString class.
//
// CDirectorySting. A subclassed CString to contain directory
// names. Two services are provided:
//
// 1. The path is always correctly terminated, saves you having to check
// for the last backslash character
// 
// 2. Includes 4 macro's for obtaining the windows directory,
// the system directory, the current directory or a directory
// name based on the date. Eg. CDirectoryString dir=[windowsdir]temp;
// will automatically be changed to c:\windows\temp\
//

// If you can improve on the code, great, if you would be so kind
// as to let me have a copy of your changes, I would appreciate it.
//
// Feel free to use and distribute. May not be sold for profit.
