The reason for this warning is because:

For historical reasons, MFC supports both Unicode and MBCS (Multi-Byte character set), but Unicode is becoming more popular, and MBCS is increasingly being used, so the new version of MFC has used MBCS as an obsolete method, so with the new When the version of Visual Studio compiles the MBCS program, this warning message appears, suggesting that you discard MBCS in the new program and use Unicode.

However, for the old version of the use of MBCS VC + + program, we do not intend to migrate it to Unicode, and do not want to see a lot of C4996 warning, how to do? Turn off the compiler's C4996 warning and need to add no_warn_mbcs_mfc_deprecation to the preprocessor definition .
