Your CString buffer has no length prior to calling GetLBText. The passed
in buffer must be sufficient size to hold the return string and null
character. Try adding:

      n = m_Drive1.GetLBTextLen(nIndex);
      m_Drive1.GetLBText(nIndex , buffer.GetBuffer(n)); // allocates buffer
      buffer.ReleaseBuffer(); // need to call Release after GetBuffer
      FindFileExample((LPCTSTR)buffer);
