问题 I am trying to capture Ctrl + C . I have noticed that many times, there is no KEY_UP event for C key. I believe it happens in cases KEY_UP event for C key should be thrown just before or after KEY_UP event for Ctrl key. Why does this happen? How can I catch the KEY_UP for C key? 回答1: Everything works fine: <?xml version="1.0" encoding="utf-8"?> < s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx"> <fx

问题 Is it possible to call a function asynchronously in Flex? I want to parse a file at regular intervals without blocking the rest of the application, what is the recommended approach for this? 回答1: Actionscript doesn't support multithreading, which I think is what you are really asking about here.

问题 I'm looking to grab cookie values for the same domain within a Flash movie. Is this possible? Let's see I let a user set a variable foo and I store it using any web programming language. I can access it easily via that language, but I would like to access it via the Flash movie without passing it in via printing it within the HTML page. 回答1: If you just want to store and retrieve data, you probably want to use the SharedObject class. See Adobe's SharedObject reference for more details of that

问题 I am playing a flv video using the videoplayer class of flex. (all the properties of it are being set at runtime) I want to make the video fullscreen without clicking on the fullscreen button i.e. through programming. Is it possible.

问题 So, I've got this code: import flash.display.BitmapData; import flash.display.Bitmap; import flash.geom.Rectangle; import flash.utils.ByteArray; var bmd:BitmapData = new BitmapData(10, 10, true); var seed:int = int(Math.random() * int.MAX_VALUE); bmd.noise(seed); var bounds:Rectangle = new Rectangle(0, 0, bmd.width, bmd.height); var pixels:ByteArray = bmd.getPixels(bounds); Is there a way to get, efficiently and quickly, the dominant color and/or the average color in pixels ByteArray. noise

问题 Chrome doesn't want to let me access javascript from swf file directly in the URL bar (I know that isn't best practice, but that's what I am trying to accomplish): Given: /file.swf?cmd=alert(); With the following code (snippet): flash.external.ExternalInterface.call("eval", cmd); This only works in Firefox and not in Chrome. I am taking this approach because in chrome the actionscript 2 way to run JS was to use getURL("Javascript:...., however this doesn't work in Chrome either anymore. Is
