Converting an MFC project to UNICODE

You might need to do this, not because you're planning on creating a Mandarin version of your code, but simply because you want to compile your legacy code under .NET.

The Find and Replace function from VS2005 comes handy.

• Replace hard-coded string "blah" with _T("blah"). Use regular expressions: The best regular expression I found so far is the following:

~((_T.)(\#include ))("[^"\)]*")('[^']*')

although it's still not perfect.

• Replace LPCSTR with LPCTSTR.
• Replace SQLCHAR with SQLTCHAR .
• Replace char with TCHAR (rather than wchar_t which would work only in UNICODE).
• Replace strcpy with _tcscpy.
• Replace strncpy with _tcsncpy.
• Replace atoi with _tstoi.
• Replace strlen with _tcslen.
• Replace sprintf with _stprintf.
• Replace atof with _tstof.
• Replace itoa with _itot.
• Replace strcmp with _tcscmp.
