摘 要

　　 随着技术的发展，媒体素材类型也增多，随着硬件技术的提高，媒体技术已为各类人员广泛使用，开发制作这一播放器具有现实意义，它与现有的媒体资源应用状况紧密结合，既具很强的直观感，又不失一般性。
　　　媒体播放器，又称媒体播放机，通常是指电脑中用来播放多媒体的应用软件，例如Windows Media Player等。它可以播放MP3、AVI、MPEG、WMV等多种视频音频媒体文件的播放，有的比较高级的甚至还可以对媒体文件进行简单的编辑。由于在Windows Me的中文Windows一直都把 Windows Media Player 称作媒体播放器，所以媒体播放器在电脑老用户中成了Windows  Media  Player的代名词。当然，到了现在我们有了更多的选择，目前比较常用的媒体播放软件有暴风影音、迅雷看看、RealPlayer、Windows Media Player、KMPlayer等。其功能也越来越多，已经不仅仅是播放器。但是相对于众多的使用群体来说，很难使一款软件来满足大家的要求，有的人也开始自己动手开发媒体播放器。
　　　利用MFC强大而全面的类库，结合ActiveX控件资源开发一款简单而实用的多媒体播放软件，可以分别通过按钮和菜单实现媒体文件的打开、播放、暂停、停止、循环播放、关闭等功能。同时具备自制的播放列表，可以按照列表的顺序实现上一曲、下一曲的播放。

Abstract
　　
　　Material type also increased with the development of technology, media, with the improvement of hardware technology, media technology has been widely used for all kinds of personnel and development make this player has the practical significance, it combined with existing media resources application status closely, both has the very strong intuitive sense, and general.
