ActionScript 3.0 :: Uploading Multiple Large Image Files Times Out?
Jun 28, 2010
I coded a multiple file uploader using the FileReferenceList and PHP. It works great for me all the time on my Fios internet connection, which is by far faster then DSL, etc... So my issue kinda went unnoticed until I got on a DSL connection. Now, many of the files I was uploading seem to be timing out, but there is no indication of this. No errors, etc... just stops its progress and NEVER finishes. Tried bumping up the script execution time on the server
What are, nowadays, the best practices for uploading a large file (which may cause a timeout) with ASP.NET Web Forms and/or MVC? Increase Server.ScriptTimeout (only for the specific POST request); Use some flash client-side uploader like swfupload ([URL]) or plupload ([URL]), but Flash uploads have some issues with proxies; Use some gmail-like javascript (like [URL]
i am currently working with flash based fashion website. here i am uploading large image and thumbnail from xml. i also have menu navigation at top. my code structure is detail below:
[Code]...
my problem here is like i have home button with 5 thumbnail and handbags with 2 thumbnail when i click home button will display 5 thumb with large image and again when i click hangbags buttom it will display 2 thumb which is what i want but 5 home thumbs keeps on remain at back. dont know how to remove them upon new button click
As known, each subsequent time that the FileReferenceList.browse() method is called, the FileReferenceList.fileList property is reset to the file(s) that the user selects in the dialog box. And my question is:
How to manage to "remember" all previously selected files, each subsequent time that the FileReferenceList.browse() method is called? so that to append new ones and upload them all later on.
I'm building an app that needs to upload multiple files to my server. Ask of these files are in one folder. I was told I carnot directly tell a fileReference which files to upload, they would have to be selected manually through browse ().
I have been working on a flex uploader, where the user can select multiple files.It works fine when the files are uploaded in a queue (one at a time), however as soon as I try to have it upload 2 files at once I run into issues.
It seems that files will often lock up, and either stay at 1% until every other file is uploaded, or just not complete at all. There is never more than one file uploading at a time.Is there some issue with calling .upload on multiple files at once in Flex?
I have a image of a person that I would like to load a certain number of times in a row to show a total of how many people took part in this particular event. In total I need 166 replications of this image, is there any actionscript I can use to do this without having to create a key frame for every separate image?
This is absolutely driving me crazy. While I'm a fan of the availability of asynchronous calls in AIR, I'm finding that being forced to use them for something that should be SUPER simple is a severe limitation. So severe that I may end up abandoning AIR and writing native Android and iOS apps instead of using the shared AIR platform.
OK, now that I have that off my chest, here's what I'm trying to accomplish. I have an app that, when deployed, is relatively small. But once deployed to a user's device that user will log in using a login name/password. Once they log in, content specific to that user needs to be downloaded and saved to the local device. Since the content varies by user I can't include it in the package for deployment.
But I cannot figure out how to accomplish this: say I want to download 10 files and each file is 2-3mb and I want to show a "Downloading, please wait..." view during the download. The application cannot proceed until all 10 files are downloaded. But since from what I've seen URLStream and URLLoader are both async I cannot figure out how to block the app from opening the "View available content" and say on the "Downloading, please wait..." view.
I'm creating a movie where I need to have several copies of the same external image.It seems that when viewing the movie in Firefox the external image is downloaded only once regardless of the number of copies I make, which seems correct.In IE the external image is downloaded once each time I copy it within the movie.And that just doesn't seem right.(I've upgraded both IE and FF to Flash Player 10.)For testing purposes I've written the following code
Code: var pages = new Array(); pages[0] = "images/Page_01.jpg";
i want to reuse an image multiple times within an item renderer, is it possible to embed the image and then reuse multiple times without having to go back to the server for the image? Is this the most performant solution?
I am trying to create an interactive 3D canvas, e.g. it loads up the person image and loads it into several - pre warped- movieclips... trouble is when I run this:
ActionScript Code: function imageLoaded2(e:Event):void { canvas_wrap_mc.canvasF_mc.addChild(imageLoader2);
[Code]....
It only executes the last one instead of them all, when I remove the last one (canvas_white_mc)... it goes to the next last one canvas_black_mc...
I'm obviously doing something wrong, and everything about addChild and loading external images for me is a bit loose weave!
My website allows users to upload photographs which I store on Amazon's S3. I store the original upload as well as an optimized image and a thumbnail. I want to allow users to be able to export all of their original versions when their subscription expires. So I am thinking the following problems arise.Could be a large volume of data (possibly around 10GB)How to manage the download process - eg make sure if it gets interrupted where to start from again, how to verify successful download of files.Should this be done with individual files or try and zip the files and download as one file or a series of smaller zipped files.Are there any tools out there that I can use for this? I have seen Fzip which is an Actionscript library for handling zip files. I have an EC2 instance running that handles file uploads so could use this for downloads also - eg copy files to EC2 from S3, Zip them then download them to user via Flash downloader, use Fzip to uncompress the zip folder to user's hard drive.
What I'm trying to do is quite simple. Load an image externally, then display it (addChild it) multiple times, in different places, without loading it again and again. (Granted, caching means the image won't be downloaded multiple times, but I'd like to avoid those annoying disk accesses as well.) I know that flash doesn't actually support this. A while ago I was trying this same thing, I dug around for hours, and there was no real solution.
I am trying to create a web site suing adobe Dreamweaver and flash, for the first time.I am trying to upload a webpage that contains swf.When I check mu site I could only see a blank page with the webpage title at the top of the page.When I contacted the webhosting company they say they can see the message that a newer version of adobe flash player is required. From my computer I cannot even see the message.The helpdesk person said there are possibly two reasons for it. Either there is a problem with the code in flash or it is too large.Are they too large to upload? If so, what is the maximum size of file can I upload on a webpage?I know they are basic questions but I am trying to create website on my own.
My users upload a certain kind of text file that sometimeshas references to images stored locally on their hard drive. I needto check this file either on the server or within a flash app tosee if it has these references and then grab those images in aflash app to upload to my server.So I can use FileReference easily enough to have users uploadlocal images. But FileReference requires users to select their files with a dialog box. I can't have that. Myusers wouldn't know where to look and there are typically way toomany files, sometimes with the same name but in differentdirectories.
I can also just use URLLoader with a local URL, I guess I canprobably just use Loader too? That works great. The problem here isI can't communicate with both the server and the local filesystemin the same flash application due to Flash's security sandboxrestrictions. So I can get out of those security restrictions byplacing or editing a trust file in designated locations on variousOSes. I then need to install this trust file which is more invasiveand confusing to users then I want to be...Java's method of accessing local files from a web applet bysimply signing the applet with a certificate and having a dialogbox popup where the users grants access is ideal. Is there anything
I was messing around with some old examples, and I ran into an unfinished example where several 30k-100k XML files are loaded and stored as a string into an Array. The code looks basically like:[code]Basically, when I trace the 'this', the order of the files that are loaded is off. Out of about 10 tries, about 3 times the order is perfect. The remaining 7 times, the order is a bit off. Does anybody have a suggestion on how to ensure the files are loaded prior to the next file being loaded? I tried placing a while loop that basically delays the clock for a few milliseconds, and that didn't work either. Besides, that is not really a good solution to arbitrarily waste clock cycles.
After browsing for the images, and selecting them. How can I display a preview of the image in the datagrid? I am able to display the file name, file size, but was unable to display the image. Below are the codes I have written, it is not a complete code but just enough to make it understandable.
// variables used var list:Array = new Array(); var listDP:Array = new Array();
As far as I know, what I ask here isn't possible, but I thought I'd ask anyway in case I'm missing something.
Suppose you want to let users upload JPG images, and these images are scaled into smaller icons and the original images are always discarded and never required again. Is there any way that would commonly work in most modern browsers that would let the user select a single image on their hard drive, have that LOCALLY turned into a thumbnail and upload the created thumbnail to a server?
In a case where the server just needs a small image, it would be wasteful both in user time and server resources to proceed uploading the whole image, only to immediately discard it. It would be much better to just scale it on the client.
I can imagine three options. Just plain HTML/Javascript, using Flash or using Java. If this were possible with Flash, that would seem like the best option. But reading flash.net.FileReference documentation, it seems that you can upload a file from the HD yes, but you cannot look inside the file you are uploading. On the other hand, if you enable "can access local files" in Flash publishing options, it seems that you can then no longer access the net, so that doesn't work.
With HTML/Javascript, it is possible to load images and display them on a <canvas>, but if you try to access the pixels of these images, you get security violations, so that doesn't seem to work.
Java I hesitate to use, because only 96.52% of my users have it installed, and the file upload dialogs I have seen implemented in Java (at Facebook for example) have not worked well (unresponsive interface). I wonder though if Java is the only thing allowing resizing images from local HD?
When I upload a file to "Up_Test.php" via a regular HTTP form, the image ends up in the destination folder and the test file wasHere.txt is created as well.
When uploading with the AS3 function above, only the wasHere.txt file is created, i. e. the AS3 connected to the PHP script, but it did not send the file.
I made my own Flash CMS where I can upload files to a server via a php-script.It works fine on PC, but stalls on Mac. Well, on Mac it actually upload the file, but somehow don't tell Flash that it's finished uploading the file so the complete-listener never gets the message.
I'm working on an application where client may upload any folder which may contain sub folders along with files. Is it possible to upload a folder instead of a file?
I am developing a facebook application which sits in an application tab.The app is developed in flash and as such must use fb:swf to embed the swf.Therefore it sets allowScriptAccess = never on the swf.There are 3 things that I will need to do, and I am not sure if it will be possible.1) Load external SWF files into the parent swf2) Load dynamic XML from the server3) Upload files to the serverI am using flash 10.
I wish users to be able to email me files. I know AS3 you can upload files (PDFs up to 25Mb). Is the best way to:1. Upload the file in flash, and get PHP to then directly email it to me2. Upload the file in flash, get PHP to save the file on a server, then email it to me3. Upload the file in flash, get PHP to save the file on a server, then email a link to me for me to download If it saves the file on the server (options 2 and 3), what happens about deleting the files as after a while they will take up lots of space.
IS there a way to upload files using the FileReference Class without using the browse() function? I would like to just tell Flash what classes to upload without the browse box popping up.
I'm writing a webbased flash application to upload big files (up to 750MB) on a server using PHP (Version 4). For small files it will work, but for large one the upload process seems to freeze. The upload "freeze" at different times and loaded MegaBytes.
Using an unobtrusive technology (HTML5, Flash, Java Applet) which runs in the browser, is it possible to handle compressing of files before being uploaded to the server? I'm building software which will be consumed by a lot of slow connections and by non-computer-savvy users and circumventing an application install would be very beneficial for them.
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?
i am doing this using variables.caption1.thecaption[0],variables.caption2.thecaption[1] etc....the trouble comes in that the number of variables have to equal the number of images....so i have to recompile this program as the number of images change...is there a way to code this with some sort of loop?
