resize a flash object

[elic05]

i use a flasher control
downloaded from this location
Steve C. Orr - Add Flash to your Web Site with this Free Custom Flasher Control
to hold a flash object
the flasher is registred in the aspx page

<%@ Register assembly="Flasher" namespace="ControlFreak" tagprefix="cc1" %>

i have a js function that gets the size of the browser window.

i want the flasher object to be the size of the browser window

i am able to control the width of the flasher only from vb like so

flasher1.width=800

the problem is that in vb i cant know the width of the browser window

how can i get this data from js into vb???

or, can i set the flasher width from inside the js function?
