问题 I am making an application that plays the video stream from the user's local system (both Windows and Mac). I use the Camera.getCamera() method and in turn Camera.names to get a list of camera attached with the system. Unfortunately, if the camera is already in use by another application, say a desktop application on user's system, the browser is crashed. Is there any way that I can detect if a specific camera from the list of available camera is already in use by any other application? 回答1:

问题 I'm trying to get properties for one single node such as the name I've set for it or something. How can I go by just selecting this one node?

The buttons don't work in Chrome/Safari or any other browser. Any ideas about how to make this work properly? If anyone has implemented something like this before in a Flex app then would like to hear about things to

问题 How does one define a default style for a custom Flex component? was a good start, but I want to create custom styles for my custom component which contains other components. The custom component is a Canvas. It contains other Canvases, Buttons, Lists, etc. I do not want to have the child components use the same values as the parent component, and I want to have some style values "jump" the parent component and only affect a specific child (not all of them). I would like to have a single CSS

How can I manage to keep the scroll bar at its previous position? 回答1: make a variable to store your last scroll position and use that. roughly something like: var lastScroll:Number = 0; private function creationCompleteHandler(event:FlexEvent):void{ stage.addEventListener(MouseEvent.MOUSE_UP,
