Mozilla ActiveX/Flash communication problem?

[Phil]

Hello,

I've got a flash slider bar which I'm trying to use to control an
embedded Window Media Player. However I keep getting the following
error when the flash fsCommand is fired:

Error: [Exception... "'Permission denied to get property
IDispatch.duration' when calling method: [FlashIObject::evaluate]"
nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)"  location:
"<unknown>"  data: no]

I've traced this back to where the code is trying to access one of the
WMP properties: player.currentMedia.duration

The site is running in Firefox 1.0.7 with the ActiveX plugin installed,
shockwave version 7.0 r19 and WMP 10 installed.

Does anyone know if this a problem with the ActiveX/Flash
communication? And if there is a workaround?


All the relevant code is below.

Thanks,
Phil


--Javascript--
//***** Writes VBScript function to capture ActiveX FSCommand event
*******
document.write('<SCRIPT LANGUAGE=VBScript\> \n');
document.write('on error resume next \n');
document.write('Sub playerSliders_FSCommand(ByVal command, ByVal
args)\n');
document.write('call playerSliders_DoFSCommand(command, args)\n');
document.write('end sub\n');
document.write('</SCRIPT\> \n');

// Accepts call from VBScript function with FSCommand parameters
function playerSliders_DoFSCommand(command, args)
{
        if (command == "skip")
        {
                skipMe(args);
        }
}

function skipMe( pos )
{
        var player = window.top.document.getElementById('player');
        if( player )
        {
                ...
                player.currentMedia.duration;
                ...
        }
}
