flash actionscript: I am trying to dynamicaly load a swf file into the one that I am creating, I
then want to put a button over the top of it.

I have figured out how to load the movie by:
loadMovie(unescape(_root.swfURL),"_root");

I want to put a button over the top and have:
on(release){
getURL(unescape(_root.linkURL),"_blank")
}

the loading works fine, but I can't get a button to float over the top of the
entire thing:
This is so I can run everything through one flash document:
example:
<object>....
src="mask.swf?swfURL=http://localhost/test.swf&linkURL=http://www.yahoo.com"
....</object>

How can I put a button over everything? Since they are different sizes, I
want to resize the button to Stage.width.
I can not figure it out, I would appreciate it if someone could point me in
the right direction.

First of all, you probably want to load the movie into a separate movieclip,
not on the root, because, where will your button be?

createEmptyMovieClip("holder",1);
loadMovie(unescape(_root.swfURL),"holder");
createEmptyMovieClip('myLink',2);
with(myLink){
beginFill(0x000000,100);
lineTo(Stage.width,0);
lineTo(Stage.width,Stage.height);
lineTo(0,Stage.height);
endFill();
}
myLink.onRelease = function(){
getURL(unescape(_root.linkURL),"_blank")
}

You are on the verge of wrting the entire document I have been working on for
three days.

As you can tell I am very new to ActionScript.

How can I make that transparent...I want the button to be transparent over the
loaded movie, so you can see the movie, but when you click it goes to the
_root.linkURL?

I tried to take out all the beginFill() stuff, but then the link is not there.
I will continue to look into this, thanks for your help so far.

Oh whoops.
Change the 5th line to:

That works exactly how I need it to...but....

I have the stage set to 100x300 and it works, I can load other movies in there
as long as everything is 100x300:

like <object>......width=100 height=300....</object>...

But then I want to load a 150x400 movie.
again: <object>......width=150 height=400....src="mask.swf?swfURL=...."

The second one (150x400) doesn't work. It is scaled down..and doesn't even
start in the top left. Can you point me in the right direction to fix these
problems?

I tried the holder.moveTo(0,0) to put it in the top left, but that didn't work.
I tried the holder._width = Stage.width, and the height, but that didn't work
either.
