If the open function does not throw an error then you need to check the return value and call GetLastError() to find out why, as described here[^]. Alternatively you can throw a new exception like:
try
{
   if (!m_definition_file.Open(m_definition_file_name, CFile::modeRead))
   {
       DWORD error_number = GetLastError();
       throw new CFileException::OsErrorToException(error_number);
   }
}
catch( CFileException e )
{
    // handle the exception
}

Note that when calling GetLastError() you must call it immediately after the failing API function call, otherwise its return may not be valid.
Use the best guess
