I have created a network trouble shooting tool in flash. The design will have all the componenets on the screen. I have to ping to every component once in minute. I have finished the design part. Please someone help me how do i ping a webaddress or IP in flash. I need a sample code.. Im using Flash CS3 What do you mean by you have all the components on the screen and you have to ping every component once in a minute? If by ping you mean an app, what checks the time-response of a url, then you can try to play with this code: var ldr:URLLoader = new URLLoader(); ldr.addEventListener

I'm currently using the JPGEncoder from the AS3 core lib to encode a bitmap to JPEG var enc:JPGEncoder = new JPGEncoder(90); var jpg:ByteArray = enc.encode(bitmap); Because the bitmap is rather large (3000 x 2000) the encoding takes a long while (about 20 seconds), causing the application to seemingly freeze while encoding. To solve this, I need either: An asynchronous encoder so I can keep updating the screen (with a progress bar or something) while encoding An alternative encoder which is simply faster Is either possible, and how can I do it? Jason Setting up the encoder to be asynchronous

I need to send a HTTP request (and get XML response) from Flash that looks similar to following: http://example.com/somepath?data=1&data=2&data=3 I.e. having several parameters that share same name, but have different values. Until now I used following code to make HTTP requests: var resp:XML = new XML(); resp.onLoad = function(success:Boolean) {/*...*/}; resp.ignoreWhite = true; var req:LoadVars = new LoadVars(); req["someParam1"] = 3; req["someParam2"] = 12; req.sendAndLoad("http://example.com/somepath", resp, "GET"); In this case this will not do: there will be only one parameter having

public class MyClass extends MovieClip { public function MyClass():void { my_mc.addEventListener(MouseEvent.CLICK, action); } private function action(e:MouseEvent):void { trace("cliked"); } } Timeline code var myClass:MyClass = new MyClass(); addChild(myClass); I can't able to access the my_mc (placed in FLA) movieclip. How do I access? Try this: public class MyClass extends MovieClip { public function MyClass() { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); }// end function private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init);

I want to know the difference between [object main timeline] , [object Stage] and root in as3? I have read from the topic How stage, root, and MainTimeline Fit Together . But I didn't get clearly. Luke Van In I think the article you linked to sums it up quite nicely (even if it doesn't explain it all that well): To summarize: one stage, one root per SWF (which is the main timeline) and that root is an instance of a document class or the MainTimeline class if a document class isn't provided Stage is probably the easiest to understand. There is one stage per Flash Player - think of it as the

given the following function A(b:Function) { } If function A(), can we determine the name of the function being passed in as parameter 'b' ? Does the answer differ for AS2 and AS3 ? I use the following: private function getFunctionName(e:Error):String { var stackTrace:String = e.getStackTrace(); // entire stack trace var startIndex:int = stackTrace.indexOf("at ");// start of first line var endIndex:int = stackTrace.indexOf("()"); // end of function name return stackTrace.substring(startIndex + 3, endIndex); } Usage: private function on_applicationComplete(event:FlexEvent):void { trace

In Flash, the BitmapData object can be used to store bitmaps in RAM, you can later draw them to a MovieClip using the beginBitmapFill() method. How do you load an external bitmap file (.jpg) into a BitmapData object? Even AS3 code would be helpful. Cotton AS3 code to load a PNG and "get" its bitmapData var bitmapData:BitmapData; var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete); loader.load(new URLRequest("../lib/img.png")); function onComplete (event:Event):void { bitmapData = Bitmap(LoaderInfo(event.target).content).bitmapData; } Refering

Which one is faster? Why? var messages:Array = [.....] // 1 - for var len:int = messages.length; for (var i:int = 0; i < len; i++) { var o:Object = messages[i]; // ... } // 2 - foreach for each (var o:Object in messages) { // ... } From where I'm sitting, regular for loops are moderately faster than for each loops in the minimal case. Also, as with AS2 days, decrementing your way through a for loop generally provides a very minor improvement. But really, any slight difference here will be dwarfed by the requirements of what you actually do inside the loop. You can find operations that will
