How do you get/set the absolute position of a MovieClip in Flash/AS3? And by absolute, I mean its position relative to the stage's origo.

Flash programmers: how do you make your code decompile proof?

I've worked on several flash projects so far. I know my way around AS3 but I also started becoming curious about how other flash programs are written, so I decompiled a few swf files to see how they were made. (I have also read through open source projects, but I don't say that because I feel guilty about decompiling swf files or anythin...

I want to build a LineChart component where the color of the line is indicative on how high the value is.

adding alpha values to bilinear resizing algorithm

So I'm trying to take a bilinear interpolation algorithm for resizing images and add in alpha values as well. I'm using Actionscript 3 to do this, but I don't really think the language is relevant.

Flex: Figure out when the running swf was compiled?

Is there anyway in a flex application to figure out (in runtime) when the running swf was compiled? I'd like to compare this with the latest file version of the swf on the server and detect if there's a newer version on the server and if so force the user to reload their browser to get the new version.
