使用MCI接口编写能播放MP3,WAV格式的音频文件

程序信息：
程序名称：My Music Player
作者 ：CodeMore
编译时间：2016年1月31日 星期日
版本： 1.0
程序原理：使用Windows中的MCI接口
编译环境： Win 10 64位专业版 和VC2010旗舰版
本播放器有以下特点：
1.程序能播放MP3, WAV格式的音频文件，采用Windows系统的MCI（媒体控制接口）进行播放。
2.播放MP3音频文件时，能够在歌曲信息区域显示文件的tag信息（歌手，专辑，发行年份等）。采用id3lib库进行开发获取，详细见源码。
3.播放器支持4种播放模式（顺序播放、单曲循环、单曲播放、随机播放）。
4.播放列表控件支持双击播放操作，支持单击项目显示歌曲信息等功能。
5.在Win7和10 平台上支持任务栏上显示音频播放进度，xp平台未测试。
