How can I dynamically change FlashVars item "streamName" at runtime using ASP.NET?

The embedded tags don't work no matter how I do it. I did end up with what you suggest (pretty much exactly like you say). I will award you the points, only fair. However, if I might squeeze a little more out of you:  I would like to serverside write these tags to javascript that then does a document.write or a document.getElementById("someSpanID").innerHTML= javscriptVariable. Can't seem to figure that one out. (body onload fill the span or something like that). Reason being is that I'm trying to avoid that annoying "click here to activate control" which happens unless you write the flash tags using javascript.

Here is my working code that models your soluton, thank you very much!
            Dim sbFlashPlayer As New StringBuilder

            'FOR IE BROWSERS
            sbFlashPlayer.Append("")
            sbFlashPlayer.Append(Environment.NewLine)
            sbFlashPlayer.Append("")
            sbFlashPlayer.Append(Environment.NewLine)
            sbFlashPlayer.Append("")
            sbFlashPlayer.Append(Environment.NewLine)
            sbFlashPlayer.Append("")
            sbFlashPlayer.Append(Environment.NewLine)
            sbFlashPlayer.Append("")
            sbFlashPlayer.Append(Environment.NewLine)
            sbFlashPlayer.Append("")
            sbFlashPlayer.Append(Environment.NewLine)
            'FOR ALL OTHER BROWSERS
            sbFlashPlayer.Append("")
            sbFlashPlayer.Append(Environment.NewLine)
            sbFlashPlayer.Append("")
            sbFlashPlayer.Append(Environment.NewLine)

            objFlash.Text = sbFlashPlayer.ToString

You can have the literal contain a <script> tag with a single function which does a document.write() of each line in the code you posted.

An alternative method that I've found is to have a bit of script near the bottom of your page (say after the closing body tag and before the closing html tag) which does something like this:

var els = document.getElementsByTag('object')

for(i = 0; i < els.length; i++)
{
   els.outerHTML = els.outerHTML;
}

I've no idea why it works, but for some reason it does (I used it in a project a few months back).  You may have to do the same for the embeds.

"I've no idea why it works"

Works for what? Getting rid of the "Click here to activate control".
Hope that is what you mean.
You have good ideas.

Sorry, yeah it gets rid of the click here to activate.

Yeah, this didn't work. Still have to click twice to start the flash:

  <script type="text/javascript">

    var els = document.getElementsByTag('object');

    for(i = 0; i < els.length; i++)
    {
       els.outerHTML = els.outerHTML;
    }
</script>  

See the script below.

It does pretty much the same thing that your script does, however I have it in an external .js file which I reference on each page that needs it.  I believe at one point I tried putting it directly on the page and it wouldn't work for some reason, so try the script below in an external .js file.

if (navigator.appName == "Microsoft Internet Explorer") (function() {
        var onload = window.onload || function(){};
        if (document.body != null) 
        {
			document.body.setAttribute('onload', null);
        }
        window.onload = function() {
                onload.apply(this, arguments);
                var tags = ['object', 'embed', 'applet'];
                for( i=0; i<tags.length; i++ ) {
                        var elements = document.getElementsByTagName(tags[i]);
                        for(j=0; j<elements.length; j++)
                                elements[j].outerHTML = elements[j].outerHTML
                }
        }
})();

Well, I think I should make this another question and award points if it is solved. The code below of yours that I used in a javascript file that is referenced at the bottom of my .aspx page returns the first 3 "hey" alerts. But does not return the last one alert("hey 4") and only a blank screen is displayed with or without the alerts.


alert("hey");
           if (navigator.appName == "Microsoft Internet Explorer") (function() {
                    var onload = window.onload || function(){};
                    if (document.body != null)
                    {
                   
                              document.body.setAttribute('onload', null);
                    }
                    window.onload = function() {
                            onload.apply(this, arguments);
                             alert("hey 2");
                            var tags = ['object', 'embed', 'applet'];
                            for( i=0; i

Hmm, if nothing is showing up on the page, then it wouldn't get into the last "hey" since the source would appear to be empty.  Perhaps there's a malformed tag on the page which is causing it not to render anything?

Well, I take out the script reference and then the page loads.
There is a macromedia flash version detector in the body onload already.

That could be effecting it some how, I'm not sure.
