可以播放三种格式的jpg图片、wmv视频文件、htm网址。

包括该播放器实现了的基本功能包括：1.音频视频文件的打开、添加到菜单、媒体的播放、音量大小的调节、播放时间的拖动、暂停播放、停止。

2图片的播放速度、透明度、手动或者自动的调节3htm网址的播放，使之成为一款简易的媒体播放设备，能够完美的播放市面上大多数的音频、视频文件。

在程序设计中，系统开发平台为Windows 7操作系统，程序设计环境采用visual stdio。

在程序设计中，程序通过调试运行，初步实现了设计目标，本程序是基于C#集成开发环境以及access数据库、利用各种控件实现媒体播放的功能的，除了基本的播放控制外，还具有多文件自动顺序循环播放、全屏播放、静音等实用功能。
