Pass Parameters into your Flash File at runtime

One way you can get around not being able to pass a parameter in is to add a "querystring" to your swf src in the embed tag / param movie in your object tag and then look at the _url property for the movie and strip off the query part. By this I mean:

Your html is like this

<%lt%>object ...<%gt%> <%lt%>param name=movie value="Flash/test.swf?x=123"<%gt%> <%lt%>embed src="/imagesvr_ce/flashkit/tutorials/Actionscripting/Pass_Par-Peter_Jo-773/Flash/test.swf?x=123"...<%gt%><%lt%>/embed<%gt%> <%lt%>/object<%gt%>

and then in your flash file you can look up this._url which will return your full path including the movie name and the "querystring". You then use string manipulation to get the parameter value out e.g.

myURL = this._url; 
myPos = myURL.lastIndexOf("?"); 
myParams = myURL.substring(myPos+1,myURL.length); 
//this returns the querystring elements - you can now split these using split 

Hope this helps - it should work in Flash 4 but definitely works in 5 from my tests so far.
