最近有客戶問我，怎么把Windows Media Player 嵌套在自己的項(xiàng)目中。

以前我在Delphi下玩過Windows Media Player，可是在Microsoft Visual Studio 2008 沒有測(cè)試過。

到網(wǎng)上搜索了一把，果然得到很多例子。

?

其中CSDN上有個(gè)例子寫的不錯(cuò)，不過要扣5分【我就不去賺分了，呵呵】，這個(gè)是CSDN上地地址：

http://download.csdn.net/source/677561

下載文件名是： Enhanced+Windows+Media+Player+using+VS+2005+in+C#.zip

?

我這個(gè)例子就是用這個(gè)CSDN上提供的例子，是基于Microsoft Visual Studio 2005下開發(fā)的，我只是簡(jiǎn)單的把這個(gè)例子更新到Microsoft Visual Studio 2008?下，不過有點(diǎn)小麻煩，還好，我已經(jīng)解決了。

?

不多說了，直接上代碼，
