Question

Answer 1

you can add the flash vars into the URI when you are loading it

URLRequest(String("B.swf" + "?myvar=45"));

the problem is that when you loaded the string in the uri, it is put inside an Object loaderInfo.parameters so if you want to pass those parameters, you need to create a string to pass these into.

here's a script from http://ragona.com/blog/pass-flashvars-loaded-swf/ that shows how to convert that into a string array again

//:: Store loader info
var lInfo:Object = this.root.loaderInfo.parameters;
//:: Flashvars
var fVars:String = "?whee=nada"; //:: Getting the syntax change (? --> &) out of the way with a dummy var

//:: Set path + data
for (var flashVar in lInfo)
{
    fVars += "&" + flashVar + "=" + lInfo[flashVar];
}

var myRequest:URLRequest = new URLRequest(String("/myPath.swf" + fVars));
