Any way to activate Flash Fullscreen mode when flash movie loads in the browser

programming flash
1

Hi all,
I want to activate Flash Fullscreen mode when flash movie loads in the browser. Without activating it through button clicks.
I tried for this using this type of code:
function goFullScreen()
{
Stage[“displayState”] = “fullScreen”;
}
goFullScreen();
But it is not working this way, it is working when I put this type of code:
function goFullScreen()
{
Stage[“displayState”] = “fullScreen”;
}
button.onRelease=function()
{
goFullScreen();
}
thanks in advance,
Vikas.
