Can anyone tell me how to do or point me in the right direction of some resource that will allow my flash movie to capture a users webcam without showing the prompt box?

By prompt box I mean that box that appears when a flash movie requires access to the microphone or camera?

All I want to do is detect and connect with the users webcam if there is one without asking them. The camera will only be seen by the user themself as opposed to anyone else - in a 'local' environment

Anyone know how to do this? I'm using flash CS3.

Thanks in anticipation!
