Passing FlashVars to embedded SWF

Maybe you can use Javascript ?

You call a js function via the MMF's "Flash Palyer" Object.
You request the return. It's like 1+1=2 LOL

Look at the mfa.

If you have multiple arguments, you can make something like this in js :
function getArgs() {
return "arg1#arg2#arg3";
}
and use String tokenizer to split arg1 arg2 and arg3 without # separator

Now it's you're turn to do the magic Take a look at documentation too

Hope I've helped you this time

It's not easy like flashVars and AS3 but we can't have all the things we need. MMF give us the simplicity for everything else

SO! Now, If I have correctly understand, you can do this with javascript too!
You have to use the SWFObject api (you can find this on google code : Please login to see this link.)
and make a function like this :

function callSWF(parameters){
var so = new SWFObject("movie.swf", "mymovie", "200", "100%", "7", "#FFFFFF");
so.addParam("quality", "high");
so.addParam("wmode", "transparent");
so.addParam("flashvars", parameters);
so.write("flashcontent");
}

It's a succinct exemple, sorry :s
But I don't use JavaScript so... It's just a tip to put you on the right way.

I believe I've helped you this time, REALLY ! LOL
