Get div size in swf?

Hi everyone!

First question. I think it’s hard.
Is it possible to get “real display size” (not Stage or _root size) of swf - the size of swf that is presented on a html page (f.e. DIV size of [100%, 100%] embedded swf) - by swf file in as without changing html page (without adding some js functions and so on).

Thanks in advance.
