I'm doing an Image Cache following this method: [URL] I copied the two as classes, renaming them CachedImage and CachedImageMap. The thing is that I don't want to store the image after being loaded a first time, but while the application is being loaded. For that, I've created a function that is called by the application pre-initialize event. This is how it looks:

I have a media player, which rotates images for the artist it plays. I load the images dynamically into the flash. The flash downloads the same images from the server over and over, how can i cache the images, so flash grabs them from a local cache and not from the server?

View 1 RepliesWhat I would like to know is, if someone has scored points on a game i'm creating - could that be stored as a "value" that could be displayed at the end of the game in another frame ?
Here's what I have at the moment
A dynamic box with the description and var of "score"
An action on a frame with the script:
score = 0;
A button that once clicked runs this action script (which adds to the score):
on (release) {
_root.score += 100;
}
Is there a way afterwards to get the total amount from "score" to be used elsewhere ?
We have a web app. built in flash that allows customers to upload images and text, customize the container in which these will be shown (a swf file) and then embed the code into thier website. There is also a sharing options that allows their users to display this container, together with the content, on their websites. (For e.g you can see the container as the Youtube player and the content as the videos the user chooses to show). The swf container uses an XML file to know what to display.
Now, I am not a flash developer, but a person who takes care of the project.We are currently working on the app and the swf and we still find bugs. Every time we fix sth, I am told to erase my cache to see the changes. My concern is that the client/users might not see the newer version that we make available, but the old one. We can't tell them to erase the cache and we can't afford to renounce using the cache since the images are big.I was told that, sometimes, the browser does not see that the current version is a new one and loads it from the cache (actually, it never detected that there is a newer version and I always had to erase the cache). How can we tell the browser "now, load the swf from cache" or "now, don't load the swf from cache".
There must be a kind person out there on the WWW who could spare me 5 mins and rescue me before I top myself! I have a movie clip on my stage with 8 buttons in it that all sequentially fade in via an alpha tween 0 to 100%. All the buttons simply link off to different URL's on click. What I want to do is when a button is clicked I want to store pressed along with the date and time it was pressed into a .csv file.
View 1 RepliesTrying to work out how I can tell if a downloaded file came from the cache or was freshly downloaded over the net. I need this because users will download multiple files and I am trying to give make an accurate downloader for them. I have made them download a sample file which I have made not to cache by doing the following:
private var _loader:URLLoader;
private var _rootPath:String; = "http:/example.com/speedTest/f4v/";
private var _startDownloadTime:int;
[code]......
If I load an swf into a movie clip, and then load another swf into that same movie clip. Is the first swf stored somewhere or is it totally gone when the second swf is loaded? What I want to know is if I need to have as many movie clip holders as I have swf's. Else they would have to load every time they were called.
View 7 RepliesI used Gaia framework to build a self-scrolling slideshow. There are only 4 pages in all, but I have realized to my dismay that each of these pages are requested over and over from the server. If you leave the page open and the animation goes by itself, that can clobber our server.
What can I do to prevent this? I wonder if there is a way of writing a URLRequest so the pragma header can tell the browser to use the swf from its cache rather than requesting it again?
Note that I am not using SWFaddress so the requests are going to the same URI.

This is my first post here in StackOverFlow, and I bring you a problem that is hauting my development team.
We are in a project, using stand alone FlashPlayer as a news displayer.The news feed is a dynamic XML returned from a ASP.Net request and runs on Windows XP.
The problem is:- The display is running in a bus screen and sometimes the internet connection fails, but we still need to keep displaying images from the news already downloaded. When we manually put a string on a URLRequest it works. The image is downloaded from the server, cached by the IE8, and re-loaded from cache if the internet is gone. But, when we dynamic retrieve the image url from de XML and puts inside de the URLRequest method, the re-load from cache do not work.[code]...
I've made an image gallery which loads images from an XML-specified folder. My function doGallery(urlPath); is using an URL-Path as an argument, which allows me to load new images and create a new gallery with these at runtime.The function will store loader objects in a gallery array, which is then cleared and overwritten once a new gallery with new images are made.So far so good. However it seems as if I have to re-download the same images as I have already once loaded, if I decide to go back to a previously visited gallery. I assume this is because I overwrite and clear the array which contains my previous loaders. Could anyone confirm this and possibly offer a solution? I hope I'm making myself clear enough for you to grasp my issue here.
View 0 RepliesThe whole problem is in the title. I have a gallery which looks a lot like coverflow. Each button in it loads a new gallery which is a swf with a new XML. The Problem is it only works on the first time i click on a button. The XML does not renew when i click on another button. It does load the new XML.

i working on a project that load images localizend on a server. For optimize the RAM usage i remove the images when they aren't shown, and re-load them when is necessary.
But are this images saved into the PC cache so that the second, third, forth... time that i call it, they will be loaded instantly? Or flash need to download it every time from server?
I'm working on a chat application that retreives user profile icons from remote sources (e.g. Blogger, Yahoo, Gravatar, etc). Easy to get the images in a Loader and display them. The problem is that a single thread could have hundreds of records, but probably only 10-20 active commenters. In a standard browser, each <img...> link after the first one is cached, so you only hit the source site once. Is there any way to cache/store/copy those images within Flash to avoid requesting the same image over and over?
I can do it in the Local sandbox by accessing the BitmapData of the loader content and cloning a new bitmap for subsequent instances of the same request URL, but of course once the application moves to the Internet the security system requires a Policy file allowing bitmap access. I don't need to manipulate the bitmap at all, just copy it. Or reference it as content from multiple Sprites, or something along that line. Once I've downloaded the image once, I don't see why the security system would prevent me from displaying it unchanged as many times on the page as needed.
I've uploaded my slideshow swf to my WIP website (CSS files got overwritten ) Everything is working great. It's looping, I have a preloader animation, ect. The problem I now want to resolve is getting the loader to cache the image files. When the slideshow is told to go back to image[0], it reloads it again. As the whole point of this project was to work around my free web hosting's bandwidth limits, as well as getting more experience working with XML, this simply wont do. Imagine if someone browsing my site left the main page running for a few hours! What I need it to do is to somehow force the browser to cache the images once they are loaded, or at least I think this is what I need to do? Here's the code again:
Code:
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;

I have an issue with downloading an image from a URL that is not getting updated at runtime. I'm using a URLLoader to download the file initially at the start of the app from some URL, then later on there is a call to the server which re-compiles the image into something else. After that the image is being downloaded again from the exact same URL, but as far as I can tell it's not getting the updated version, but is getting it from the cache that flash creates.
If I restart the application after doing all of this it gets the correct image when it downloads at startup, but I cannot for the life of me figure out how to get it to download the correct image at runtime. Does anyone have any idea how this can be accomplished?
I'm having trouble trying to cache a movieclip that contains an external image that I have successfully loaded. My problem is that the fade function that is running when after the image is duplicated doesn't appear to be affecting the mc that contains the cached image.Is there a handler that I can use to ensure that the bitmap is attached inside the movie clip before I run my fade in, or do I have to beware of a timing issue and delay running the setInterval for the fade in?
bmppopulatedClip.onLoadInit = functiontoRun; or something?
Here's my code that doesn't work:

does anyone know a good way of unloading content from loader object? I want to load a same image few times (backend overwrites old images with new ones) and all I get is bitmap data that is initialy being loaded the first time. So I guess bitmapData is stuck in cache by default and I cant get rid of it. I tried following:
loader.unload()
loader.contentLoaderInfo.content.unload() before each load() call
setting loader object to null

I am using an array to store images that I load from xml. I have an enterframe event that transforms the image, it changes the width. I have used concat to make a "copy" of the array of images. When I try to access the first array of the "untouched" images the width is changed. How can I always have a "fresh" array of the images?
View 3 RepliesSuppose you have a slideshow movie that loads content such as images or Flash movies itself and continually replaces content with new images or movies as a viewer browses through content. Is there a way to store images or movies that have been loaded so that if the same content is selected they do not have to downloaded again? Presumably once content has been unloaded or something has ben loaded into the same level the data is wiped from memory and has to be downloaded if it is displayed again. How could content be stored in Flash or does the content stored in the browser cache take care of this?

I'm just trying to store a simple cookie that will remember the score for the next time the user plays the game (the score governs if an option is visible or not)It all works fine until I close browser/reload the page, at which point the shared object seems to disappear, any clues?
Write:
Code:
var rem_score:SharedObject = SharedObject.getLocal("score");
rem_score.data.score = new Number(score);
rem_score.flush();
The problem prolly lies in my write code but ill post the reading aswell just incase there is a problem with that too
Code:
var rem_score:SharedObject = SharedObject.getLocal("score");
if (rem_score.data.score != undefined) {
this.remdscore = rem_score.data.score;
if (rem_score.data.score >=30) {

In my Flex application, I've got a component that extends UIComponent where I'm loading images at runtime and try to display them. I've tried lots of different approaches (using beginBitmapFill(), using different containers), but I can't get things to work as I want. The problem seems to be related to the width and height properties of the image, which aren't updated correctly.The idea is:
var sprite:Sprite = new Sprite();
addChild(sprite);
var im:Image = new Image();[code].....
The image's width and height doesn't seem to be correct when it's loaded. I get width==0 (and nothing is displayed), but the property $width seems to be correct. How can I assure that width and height of the loaded image is updated?
I'm trying to read the width and height of a locally loaded image. This seems to work for images that do not exceed the dimensions limited by the Flash Player 10 [URL], but as soon as the images are bigger, the width and height remain 0. The strange thing is that now and then, I can read the dimension of these bigger images, but most of the times not. I understand that this might be because of the player limitation, but then I would at least expect the error to be consistent.
I want to check this since there is no use in loading such a big image as it will not be displayed anyway, but it would be good to provide a detailed error message to the user.
Here's the code that I use to load the image locally and read the dimension:
private function chooseImageButton_clickHandler(event:Event):void {
var allowedTypes:String = "*.jpg;*.png";
m_uploadFileReference = new FileReference();
m_uploadFileReference.addEventListener(Event.SELECT,
