最近有客户问我，怎么把Windows Media Player 嵌套在自己的项目中。
以前我在Delphi下玩过Windows Media Player，可是在Microsoft Visual Studio 2008 没有测试过。
到网上搜索了一把，果然得到很多例子。
其中CSDN上有个例子写的不错，不过要扣5分【我就不去赚分了，呵呵】，这个是CSDN上地地址：
http://download.csdn.net/source/677561
下载文件名是： Enhanced+Windows+Media+Player+using+VS+2005+in+C#.zip
我这个例子就是用这个CSDN上提供的例子，是基于Microsoft Visual Studio 2005下开发的，我只是简单的把这个例子更新到Microsoft Visual Studio 2008 下，不过有点小麻烦，还好，我已经解决了。
不多说了，直接上代码，
