The HTML-Code could look like this:

<OBJECT ID="MyMediaPlayer"
classid="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95"
CODEBASE= "http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,4,5,715"
width="210"
height="23"
standby="Loading Microsoft Windows Media Player components..."
type="application/x-oleobject">
<PARAM NAME="FileName" VALUE="Your File">
<PARAM NAME="TransparentAtStart" Value="true">
<PARAM NAME="AutoStart" Value="true">
<PARAM NAME="AnimationatStart" Value="true">
<PARAM NAME="ShowStatusBar" Value="true">
<PARAM NAME="ShowControls" Value="false">
<PARAM NAME="autoSize" Value="true">
<PARAM NAME="displaySize" Value="false">
<PARAM NAME="ShowAudioControls" Value="true">
<PARAM NAME="ShowPositionControls" Value="true">
</OBJECT>



Hope that helps

You can access the MediaPlayer-Object via JavaScript like this:


parent.FrameName.document.MyMediaPlayer.FileName = "Something.avi"
parent.FrameName.document.MyMediaPlayer.play();




You have to replace "FrameName" with the name of the frame with the MediaPlayer-Object.

I do as you tell me, but when I run it, an error display: deny access. what's the matter?

A reason could be, that the two html-pages are not from the same host. IE does not allow, that you access the document-object of a page that is from another host.

You have to wait, until the mplayer has loaded the complete file. Extend the Play-Function like this:


function play()
{
if (document.MyPlayer.object.ReadyState != 4)
window.setTimeout("play()", 500);
else
document.MyPlayer.Play();
}



ReadyState == 4 means the MPlayer is ready and a value of 1 means the is loading.

Hope that helps

Thanks!
Another question: Why the following code can NOT work?
document.MyPlayer.FileName = "test\Love Day After Tomorrow- 2.asf";
//Unknow error throw
in HTML,I write this:
<param name="FileName" value>

Is there any thing wrong?
Thanks!

Ensure that the file exists. If it's not so, the MPlayer throws an "Unknown error" instead of "File not found". And you should change the backslash against a slash in your filename.
