说明：  如何才能知道 CD 驱动器是不是刻录设备呢？此外，如何将文件写入可擦写 CD？Windows XP 允许你用 Windows 资源管理拖拽文件，并将其写入CD。你能否告知有没有什么方法从我的程序中实现，而不需要用户购买第三方软件，如：Nero 或者 Roxio? 有没有相关的 MFC 类可以实现这个功能？
(CD drive is not recording equipment? In addition, how to write papers erasable CD? Windows XP allows you to use the Windows drag-and-drop file management, it was written into the CD. Can you tell what is not from the process I realized, without the need for users to purchase third-party software, such as : Nero or Roxio is not related to the MFC class can achieve this function?)
