[Qt-interest] QString to TCHAR* and back

[Nuno Correia]

Hi,
Try this code, it's work fine for my problem.

*QString to TCHAR*
    TCHAR buffer[ MAX_PATH ];
    filepath.toWCharArray( buffer );
    buffer[ filepath.length() ] = '\0';

*TCHAR to QString*

TCHAR* szMessage = _T("Hello, World");

#ifdef UNICODE
qstrMessage = QString::fromUtf16((ushort*)szMessage);
#else
qstrMessage = QString::fromLocal8Bit(szMessage);
#endif
