you can control it normally, but you just need to wait for it to actually load first…
How can I Invoke onLoad event when I am loading external swf?
thats the thing, you cant. you have to wait till getBytesLoaded equals getBytesTotal…
How can I get loaded bites of loading swf from movie in witch he is loading?
i just told you how
MovieClip.getBytesLoaded would give the amount currently loaded, and MovieClip.getBytesTotal would give you the size of the whole movie. replace MovieClip with the name of the clip you’re loading to…
