Insus.NET 你好！ 我把在Asp.net中播放mediaPlayer的详细过程给你看看（根据你的视频教程做的） 问题在哪里？

//MediaPlayer.ascx<%@ Control Language="C#" AutoEventWireup="true" CodeFile="MediaPlayer.ascx.cs" Inherits="MediaPlayer" %><script language="javascript" type="text/javascript">
 <asp:Literal ID="Literal1" runat="server"></asp:Literal>
 var oeTags='<object id="mediaPlayer" classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6"'
        +'width="'+width+'" height="'+height+'"'
        +'codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701"'

        +'type="application/x-oleobject">'
        +'  <param name="autoStart" value="false"/>'
        +'  <param name="url"       value="'+videolink+'"/>'
        +'  <param name="wmode"     value="transparent"/>'
        +'  <param name="uiMode"    value="full"/>'
        +'  <param name="loop"      value="false"/>'
        +'  <embed id    ="EmbedmediaPlayer"'
        +'     type      ="application/x-mplayer2"'
        +'     src       ="'+videolink+'"'
        +'     width     ="'+width+'"'
        +'     heigth    ="'+height+'">'
        +'  </embed>'
        +'</object>';
 document.write(oeTags);
</script>//MediaPlayer.ascx.cspublic partial class MediaPlayer : System.Web.UI.UserControl
{
    private int width;
    private int height;
    private string videolink;    public int Width
    {
        set
        {
            width = value;
        }
    }    public int Height
    {
        set
        {
            height = value;
        }
    }    public string Videolink
    {
        set
        {
            videolink = value;
        }
    }
    protected void Page_Load(object sender, EventArgs e)
    {
        this.Literal1.Text = "var width" + width + ";var height=" + height + ";var videolink='" + videolink + "';";
    }
}//VideoOnline.aspx</head>
<body>
    <form id="form1" runat="server">
    <div>
        <uc1:MediaPlayer ID="MediaPlayer1" runat="server" />
    
    </div>
    </form>
</body>//VideoOnline.aspx.cspublic partial class Video : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        this.MediaPlayer1.Width = 400;
        this.MediaPlayer1.Height = 300;
        this.MediaPlayer1.Videolink = "mediaplayer.wmv";
    }
}

这样做完后 运行没有任何错误 但是页面是空白的
什么问题呢？要是不要这个方法 其他方法怎么做？
