ActionScript 3.0 :: FileReference Type Method ... Weak
Dec 18, 2009
So there I was, creating a small app that allowed user to upload custom images. Everything went smooth, until......<insert horror music here> So you want to validate that its an image, and not something else. Well you restrict it with the File filter...but there are ways around that. So as a double check, you check the file type after a file is selected. <drum roll>
Awesome, the type method returns null if the image doesnt have the proper headers....what the hell....So most images are compressed for smaller file size, thus the headers are stripped out. So...Type method appears to be useless....There was a simple way around this using the name method..but what the hell...type method is weak!!
I am trying to get simple example of it running. I can make it work if I publish in FlashPlayer10, but not FP 9
[Code]...
The reference material says Language Version : ActionScript 3.0Runtime Versions : AIR 1.0, Flash Player 9 Does this mean the AIR 1.0 and Flash Player 9 or what is the deal?the compile error is... 1061: Call to a possibly undefined method save through a reference with static type flash.net:FileReference.
Can I implement the "load" method in FileReference in other way? My client use FP 9 and this method is implemented in FP 10. I am using BlazeDS + Spring and I want to upload images.
I am currently working in Flex 3.0 I am getting an error(screen shot is given below). I am using Flash Player Version 10.0Currently I am calling the HTTPService and in the resultHandler of that HTTPService i am getting an error in method filereference.save() .because this method is called only when the MouseEvent or Keyboard event is occured.Is there any solution to overcome this situation or in other words calling the filereference.save method in ResultHandler.
limiting or correcting the behaviour of FileReference.save isn't possible.Can anyone suggest an alternative (server is Apache/PHP) that matches all of my criteria from this post and avoids the pitfalls I discussed with Jacob?I'm saving an image from my AS3 app using FileReference.save(). This is the code, which works fine:[code]This opens up the save file dialog as expected. I'm using this rather than sending the byteData to PHP because I want the user to have a familiar dialog box that lets them set their own file name.
The problem comes when users have their operating system configured to display file extensions, like I do. This means that in the save dialog the file name contains the extension as seen in the image below, and so it is very easy for the user to delete that extension when they rename the file. Because the default file type for this box is 'All files', if the extension is deleted the file is saved with no type.I don't know of any way to force a file type on the save dialog (if there is one that would be my preferred route) so failing that can anyone suggest a safe way for me to do this that still allows the user to set the file name themselves using a standard dialog for their OS?I did try putting in a call to FileReference.browse() before the save() as shown in this tutorial, but that throws an error because you can only perform one FileReference call at a time.
how to incorporate FileReference method like Upload into a Cairngorm architecture.Specifically, I would think to fire an event with the File in it, and that's fine. But how would one then be able to listen for e.g. Progress Events?One thing I thought is to have the delegate fire off progress events that are listened for in the View.
As URLLoader launches requests without any issue (I'm monitoring network and flash activities via FireBug in FF 3.6.13), the FileReference upload method doesn't. The odd thing is that no error is thrown AND (the strangiest) the complete and the progress events are correctly fired while no request has been done, and my php isn't receiving anything !
ActionScript Code: var file:FileReference = new FileReference(); function mClick(mEvt:MouseEvent):void {
I'm going to implement a file uploading application using flex 3.5 and php. In the flex code I need to read the content of the uploaded file without calling the FileReference.load() method (Since it is a big issue when uploading large files). I checked many online articles and didn't find a way to do this in flex.access the content of this file without using FileReference.load() method?
Is there a way to set a default extension when saving an image using FileReference save method?
Code: var fileReference:FileReference = new FileReference(); fileReference.save( pngData, "image.png" );
If windows is set to "hide known file extensions", only image without extension will be displayed in save dialog. File type is "*.*". Some of my users hat the great idea to add .jpg extension in filename, because they couldn't see one. So file was saved broken as image.jpg.
I am using the FileReference class in ActionScript 2.0.Is there a way that I can receive a response in a XML format from PHP into the onComplete method of the FileReference listener?Basically, what I want to do is upload a file and when the upload is complete, I want to receive an XML format response.
I'm extending the AS3 class Rectangle with a class called Bin. I want to override the Rectangle clone() method with a method that returns a Bin object, not a Rectangle object. If I try to override the clone method but specify Bin as the return type, I get a #1023: Incompatible override error. Here's my Bin class:
package { import flash.geom.Rectangle; public class Bin extends Rectangle {
[Code].....
This class works, but when I use the clone() method to create a new Bin instance, I get type errors when I try to use the Bin methods on the new instance.
How do I override clone() and send an actual Bin instance?
Some constructor methods I've seen have the return type :void, even though they can't actually return any values anyway. If it's not required, is there a standard/best practice for that?
I need to know the best method to find an item inside a list (Vector, Array, Dictionary, whatever is faster) of complex type (extensions of Objects and Sprites). I've used "Needle in Haystack" method, but it seems that it isn't fast enough.
E.g. Suppose that I have a collection of Sprites (a pool, in fact). Each sprite will be added to the stage and perform some action. After that, it will die. I don't want to pay the cost to dispose it (garbage collect) and create another (new) one every time so I'll keep the dead sprites in a collection.
Sometimes times I'll call a method that will add a sprite to the stage. This sprite can be a old one, if it is already dead, or a new one, if the pool don't have any free sprite.
One of the scenarios that pushed me to this question was a Particle System. A "head" particle leaving a "trail" of particles every frame and exploding into a flashy multitude of particles... Every frame...
Some times this counts up to 50.000 PNGs with motion, rotation, alpha, event dispatching, scale, etc... But, this is JUST ONE scenario...
At the moment I'm trying to use a Object Pool with a Linked List... Hopes that it will be faster that running a whole Array/Vector or create new instances every frame an let them dye with Garbage Collection.
I am trying to use the load method of FileReference object to load the data and use it to display a thumbnail of the selected image.However, after calling fr.load(), fr.data remains null.I'm using Flex Builder 3.0.2 on Windows 7 with Flex SDK 3.4 and Flash Player 10 Debug. If I evaluate fr.load() in Eclipse's watch variables list, I get an error reading "No such variable: load."
Error: Access of undefined method getStatus through reference with a static type Class.
Here's what's happening in the code. I'm trying to create a User class that is instantiated at the start of my app. I want the User class to have properties like mainStatus, with helper methods like setStatus etc. Pretty simple.
so on my HardDisk I have my flash_working folder with all my flash projects. I created my class file/package under the directory com.mypackage
[Code]....
That's all the code I have.
If I try to access the public var mainStatus through user.mainStatus that gives a similar error saying:
Error: Access of undefined property mainStatus through reference with a static type Class.
I wrote a singleton class to keep track of some variables across my application.
I am getting a syntax error that I can't figure out, I am sure that I am missing something simple but it's been one of those days. Anyone see something wrong with my code?
The error is 1061: Call to a possibly undefined method setResult through a reference with static type Class.
My function in my singleton class
public function setResult(resultNumber:int, value:int): void { switch(resultNumber) {
Im trying to use the hit test built into flash, but its failing. I have used this many time before! but this time flash is crying at me. I Think i know why but im not sure how to fix it. Here is my hit test code:

I have tried multiple things, Changing instances, location of the code. I currently have 4 classes, Main, Missile, Enemy and House. House has nothing it in really. Missile make a missile, Enemy Makes a enemy. And main deals with adding it all to the stage, and making it randomly appear ect.
I was following this tutorial [URL] and I recieved this error C:UsersDevDesktopcoursework flashClassesDocumentClass.as, Line 271061: Call to a possibly undefined method setFinalScore through a reference with static type GameOverScreen. I am not too sure what that is referring too, I am also using Flash CS5
I have the actionscript code here for a bubble popping game. When the game starts, bubbles fall down from the top of the game to the bottom and score is kept for the most bubbles clicked or popped in 30 seconds.The size of the bubble is defined by the initialize method in the code, and uses ToString() to calculate the score. ToString gives me a 1061: Call to a possibly undefined method Random through a reference with static type uint. This error which I cannot figure out where it comes from.[code]
getting error 1061: Call to a possibly undefined method stop through a reference with static type flash.events:TimerEvent.on my as3 class. I'm just starting to learn as3 and cant figure out whats causing the error.[code]
I try to make working an XML loader from a custom class on a new var, but when I add an Event listener it tells me this:
1061: Call to a possibly undefined method addEventListener through a reference with static type XMLLoadData.
This is the code I have on the stage:
Code: var xmlLoad: XMLLoadData = new XMLLoadData("navigation.xml"); //load the xml file xmlLoad.addEventListener(Event.COMPLETE, onComplete); // execute onComplete once the xmlLoad is fully loaded function onComplete(e:Event):void{ // }
and this is the code of my custom class XMLLoadData Code:
I get the above error. I did actually change a little code because I put it in it's own class.I call the below ShuffleArray class in my main doc class as follows:
I've been using Adobe Flash CS4 for a couple of days. I've drawn a worm, with eyes and a mouth and these pieces are all MovieClip symbols. I have exported them to actionscript with the class name being the same as what they are (ie. the mouth MovieClip is exported as mouth). The mouth has 2 frames, one smiling and one frowning. I need to mouth to stay smiling at first, so in Frame 1 actions I wrote:
I see where i was going wrong however when i change the instance name like you said i 1120: Access of undefined property snakePart. all of this code btw is at document class level and the movieclips are in the library not on stage
