Best way to include windows mediaplayer in a radcontrol app ?

[CSurieux]

Hello,

I came in difficulties including mediaplayer in FireFox, I need to be able to click on start/stop buttons so I included javascript for this:

            <object id="Player" classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" type="application/x-oleobject"
            standby="Loading Microsoft Windows Media Player components...">
                <param name="URL" value=""/>
                <param name="rate" value="1"/>
                <param name="balance" value="0"/>
                <param name="currentPosition" value="0"/>
                <param name="defaultFrame" value=""/>
                <param name="playCount" value="1"/>
                <param name="autoStart" value="-1"/>
                <param name="currentMarker" value="0"/>
                <param name="invokeURLs" value="-1"/>
                <param name="baseURL" value=""/>
                <param name="volume" value="50"/>
                <param name="mute" value="0"/>
                <param name="uiMode" value="full"/>
                <param name="stretchToFit" value="1"/>
                <param name="windowlessVideo" value="0"/>
                <param name="enabled" value="-1"/>
                <param name="enableContextMenu" value="-1"/>
                <param name="fullScreen" value="0"/>
                <param name="SAMIStyle" value=""/>
                <param name="SAMILang" value=""/>
                <param name="SAMIFilename" value=""/>
                <param name="captioningID" value=""/>
                <param name="enableErrorDialogs" value="0"/>
                <param name="_cx" value="11377"/>
                <param name="_cy" value="11377"/>
            </object>
            <br />
            <br />
            <input onclick="PauseMe()" type="button" value="Pause" id="btnPause" />
            <input onclick="StopMe()" type="button" value="Stop" id="btnStop" />
            <input onclick="FullScreen()" type="button" value="Full screen" id="FSBUTTON" />
            <br />
            <br />
            <div id="divState">Playstate:
            </div>
            <br />
            <br />
            <div id="divStatus">Status:
            </div>
            <br />
            <asp:Label id="Label2" Text="FULLSCREEN" runat="server" /><br />
    </div>
</div>
<telerik:RadCodeBlock id="CodeBlock1" runat="server">
<script type="text/javascript">
var g_bPaused = false; // To track pause button state;

// Initialized states.
function InitMDP()
{
    try
    {
        document.getElementById("btnPause").disabled = true;
        document.getElementById("btnStop").disabled = true;
        if (document.getElementById("Player").object.enabled )
        {
        document.getElementById("Player").uiMode = "none";
        }
        }
    catch(ex) {
        alert(ex);
        if ( document.getElementById("Panel1") )
            document.getElementById("Panel1").display=true;
    }
}

I get an exception in InitMDP "Player" 'has not this property' (but it works in IE), even trying to delay its execution in codebehind using

        protected override void OnPreRender(EventArgs e)
        {
            string scriptString             = "InitMDP();";
            if ( HasAjaxManager )
            {
                // We must execute this on end of page loading by browser
                AjaxManager.ResponseScripts.Add(scriptString);
            }
            base.OnPreRender(e);
        }

I don't understand, am I stopped by some FF feature ?


Thanks for idea.
