这里是WMP的版本ClassID,从WMP7后ID就成了clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6,之前的6.4为clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95,但是之前的版本还是可以用的,只不过新功能用不了罢了。

下面这个是具体的版本号,你可以对比一下你现在的是什么版本。

官方的插入方式真够简单的,我都有点想踹他们两脚,

<OBJECT ID="Player"
  CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6">
    <PARAM name="autoStart" value="True">
</OBJECT>
下面是具体参数在不同浏览器的可用性,这个东东真是太有用了,好多参数用了不起作用,我都测试的快疯了,一看这个列表,原来人家压根不支持,晕...

PARAM name Internet Explorer Firefox with mime type application/x-ms-wmp Firefox with any other mime type autoStart yes yes yes balance yes yes yes baseURL yes yes yes captioningID yes yes yes currentMarker yes yes yes currentPosition yes yes yes defaultFrame yes no no enableContextMenu yes yes yes enabled yes yes yes enableErrorDialogs yes yes no fileName no yes yes fullScreen yes no no invokeURLs yes no no mute yes yes yes playCount yes yes no rate yes yes yes SAMIFileName yes yes yes SAMILang yes yes yes SAMIStyle yes yes yes SRC no yes yes stretchToFit yes yes no URL yes yes yes volume yes yes yes windowlessVideo yes yes yes

 参数的默认值:

 可能你最想知道的是怎么用程序(我偏向用JS)来控制WMP的播放、停止、快进吧,看看这里吧,http://msdn.microsoft.com/en-us/library/dd564034%28VS.85%29.aspx,有详细的说明和例子。(英文的)
