MFC 版で，iFileFind としているのは，VC 6 MFC MBCS 版でのバグのため．
class iFileFind : public CFileFind {
public:
virtual CString GetFilePath() const {
ASSERT(m_hContext != NULL);
ASSERT_VALID(this);
CString strResult = m_strRoot;
#ifdef ____VC_6_______MBCS_BUG___
{
if (strResult[strResult.GetLength()-1] != '\\' &&
strResult[strResult.GetLength()-1] != '/') {
strResult += m_chDirSeparator;
}
}
#else
{
LPCTSTR pszResult;
LPCTSTR pchLast;
pszResult = strResult;
pchLast = _tcsdec( pszResult, pszResult+strResult.GetLength() );
VERIFY(pchLast!=NULL);
if ((*pchLast != _T('\\')) && (*pchLast != _T('/'))) {
strResult += m_chDirSeparator;
}
}
#endif
strResult += GetFileName();
return strResult;
}
} ;
MFC 7 以降であれば，CFileFind として利用可能．
