how to check whether the URL given to URLRequest really exist or not? for e.g.,
var a:Loader = new Loader();
var b:URLRequest = new URLRequest("C:/123.jpg");
now here, how can I check whether the URL given to variable " b " is really there or not?
var a:Loader = new Loader();
var b:URLRequest = new URLRequest("C:/123.jpg");
a.contentLoaderInfo.addEventListener(IOErrorEvent. IO_ERROR, error);
I'm working on a tile game and need to figure out an equation.. I have a grid which is 12x11.. when I place a tile I need to check the existance of other tiles on the same row and column and add up their values..I need to create an equation with the following variables :-
Receives a number between 1 and 132 :-
divides and/or multiplies the number into all the possible divisions of 12 in between 1 and 132 adds or subtracts the correct amount of tiles which lie either side dependant on it's position(I have drawn out the grid, and, for example, tile 66 has five tiles either side, tile 121 has 11 to it's right because it's in the bottom left hand corner)
I'm making a game where you place tiles on a grid. When placing a tile, I need to check the existance of another tile to the left, right, or above and below, otherwise the tile should not be placed.. Here is a function I thought would work, that accepts one variable (the position of the tile just as it is about to be placed) :-
private function checkSurroundingTiles(gridPosition:uint) { var t1 = gridPosition - 12; var t2 = gridPosition - 1; var t3 = gridPosition + 1; var t4 = gridPosition + 12; for(i = 0; i < gridRefArray.length; i++) { var checkTile = gridRefArray[i]; if(checkTile == t1) { return true;

lately i've associated a class file (.as) to my movie and immediately after, when publishing the movie i got the following error message: 1046: Type was not found or was not a compile-time constant: URLRequest. as well as a couple of other related error messages: 1180: Call to a possibly undefined method URLRequest. 1180: Call to a possibly undefined method navigateToURL. when i remove the link to the class file, the problem goes away. also, i have checked the class file for mentioning of "URLRequest" and nothing is there.
I'm loading images via a URLRequest and Loader classes and I want to manage the image when the request is complete. The example below doesn't fire the event when it is complete. The same code would work find for a URLLoader, but not a Loader object. Basically the image loads and the event listener is never fired. Can anyone tell me how to get an event to fire when Loader finishes loading an image.
var imageReq:URLRequest = new URLRequest("http://www.google.com/images/nav_logo29.png");
var imageLoader:Loader = new Loader();

I will use the URLRequest to upload the modified image in Flex. It works fine. However, I need to add Content-Length as a URLRequestHeader for the moment, and I get error 2096. Then, I know that this header is not allowed.

In Actionscript 3, I'm trying to build a button to go back from a content frame to a main menu. When the button is clicked, IF the content frame has a movie in it, that movie should stop playing. Flash keeps throwing a "null object reference" error on all pages that don't include a movie. I even tried putting in a check to see if the movie exists, but that doesn't work, either.
ActionScript Code:
function return_to_menu( me:MouseEvent ):void {

View 7 RepliesThe following is my codes. This is still work in progress; so, you will see some functions with empty contents. Plus, this is my first Flex application; please bear with me. This is a quiz application that gets the questions and answers to each questions from a ColdFusion web service. There are three types of questions, True or False, Multiple Choice with single selection, and Multiple Choice with multiple selections. So, based upon the question type, the application would dynamically generate the appropriate amount of radio buttons or check boxes for the users to select. I got these working. The problem that I am having is, I am not sure how to check what the users have actually selected. In some other forums and posts on other web site, it said that I can use event.currentTarget.selectedValue to get the user selection. But when I actually do it, I got a run-time error saying, "Property selectedValue not found on mx.controls.FormItem and there is no default value." My question is, what do I need to do to capture the user selections?

I have the following actions in my file :
var xmlLoaderA:URLLoader = new URLLoader();
xmlLoaderA.addEventListener(Event.COMPLETE, LoadSomething);
xmlLoaderA.load(new URLRequest("my url"));[code]....
now imagine that the loading of the file is completed and we are in the "LoadSomething" function. How can we trace "my url" in this function? In another word I want to wite this action:
trace(Command);
and I want "my url" string in output.But I dont know what is the Command.

working my way through some tuts, and have set up WAMP. Trying to send some vars from AS3 to PHP to update a mtySQL table.My issue is that the php file does not seem to be receiving the variable info from flash, why not?
Here is the AS code
Code:
submit_btn.addEventListener(MouseEvent.CLICK,onClickSubmit)
function onClickSubmit(event:MouseEvent):void
{
var loader : URLLoader = new URLLoader();
[code]....
The PHP works cos when I run it from a browser $sd3 updates the database field to 78.This the output of the 'trace' statements
clicked
sd1=77&sd2=88&nickname=test1
The reason is probably simple but I can't see it.
I cannot ascertain why the code for one set of navigation buttons I've created works, but similar code does not. The code is rather lengthy, but I've pulled out the salient components to see if the Interwebs could help.
Here's the script that IS working:
Listener code:
Code:
cswordbutton.addEventListener(MouseEvent.CLICK,fetchcswordassets);
And the function code that goes with it:
Code:
function fetchcswordassets(e:MouseEvent):void{
var url:String = "knowntomeURL";
[Code].....
1) All of the actions are in a separate layer in the first frame;
2) There is only one scene;
3) I've given the same button a different instance name in many cases, to coincide with different expectations (URLs).
i have this code
public class TextboxXML extends Sprite

//XML[code]....
i want to get the xml-data. the xml will be generatet out of a php-function.testing it out of flash by "testing the movie" (apple+return), the php will be parsed and it works. when i test it on my lokal server, the same smf i mean, nothing happens.
I have an xml file which contains multiple products each with their corresponding background image, foreground image, text and website. The LoadXML class loads this xml file and creates an array of each image, text and website. The Main class then loads each image from the array of background images in the method onBackgrLoad(). This is done through the use of a for loop which loops through the array of backgrounds (called hintergrund[]) and loads each one in turn. On tracing hintergrund[] I sucessfully receive a string of all the different background image paths. However when I examine the backgrRequest and backgrLoader they both contain null. The images therefore dont appear on stage but neither does an error message appear! The same thing happens for onImageLoad (this should load the foreground image) and onTextLoad.
