篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了如何在ASP页面中实现音乐播放的功能（指用播放器播放）？相关的知识，希望对你有一定的参考价值。

就是比如 1.小酒窝林俊杰试听
2.国境之南范逸臣试听
点试听之后，网页中的播放器可以自己播放音乐。
不知道怎么把播放器放进代码里，希望有高手能帮我解决这个问题，小弟先谢过了。还有试听那部分代码怎么实现呢，或者网上有类似的，希望给个链接。

怎样在VC++中实现播放MP3背景音乐

最近急需用到背景音乐，找到了播放 wav 的方法，不过这种格式太难找了，而且太大了。
在不涉及MFC 和 D3D 的情况下，
如何让其播放MP3音乐。

什么都不要，麻烦直接告诉我代码就可以了。多谢。

分数有限。只能给10分了。。。多多海涵。
麻烦给我个全面的。。。。整个代码。能运行的。。

两个类：CSound、CMusic
共有两个头文件和两个cpp文件：

使用时声明一个CMusic类对象，然后用他的成员函数就可以播放支持的音乐文件了参考技术A sndPlaySound这个函数好像不能播放mp3的。
可以使用mciSendCommand函数来进行处理，还可以进行播放控制。具体可参照MSDN。参考技术B sndPlaySound
