实例介绍
【实例简介】原理：使用 Windows Media Player，使用 IrisSkin 可换肤
【实例截图】
需要启用 Windows Media Player 功能，否则会提示【System.Runtime.InteropServices.COMException:“没有注册类】
操作步骤：控制面板>>程序>>启用或者关闭windows 功能>>选中 媒体功能>>Windows Media Player,点击确定即可

小贴士
感谢您为本站写下的评论，您的评论对其它用户来说具有重要的参考价值，所以请认真填写。
- 类似“顶”、“沙发”之类没有营养的文字，对勤劳贡献的楼主来说是令人沮丧的反馈信息。
- 相信您也不想看到一排文字/表情墙，所以请不要反馈意义不大的重复字符，也请尽量不要纯表情的回复。
- 提问之前请再仔细看一遍楼主的说明，或许是您遗漏了。
- 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦，又没人会搭理，于人于己都无利。
