Chinese internal code conversion class
??? Chinese is divided into Simplified, Traditional, and there is also a unified code. If you want to convert between different codes, you need to have a corresponding form, and the program is very cumbersome, and there is a built-in control form. The author, I found that as long as the MULTIBYTOWIDECHAR and LCMAPSTRING two functions can be simply implemented. In order to make the programmer more convenient, the author wrote a CCHINESECONVERTOR class and packaged all the Chinese internal code conversion function. The reader can join this in the MFC directly, it is very easy to use. Detailed details Please see Chineseconvertor.h and Chineseconvertor.cpp source code.
This source code complies with the GNU unpaid to the reader, no copyright restrictions.
