How can I dynamically pull the value from the object in the list to load the child mxml file into the container that I have further down in the application?

Flex :: Include An MXML File Inline Another MXML File?

Jul 25, 2011

I would like to include an MXML file in my MXML file in the same way you can include an external file in AS3 using the include directive. Using the include directive brings the code from the external file into the original file at compile time placing it in the same scope. For example,

Application.mxml:
<Application>
<source="external.mxml"/>

Javascript :: Image Dimensions = Client Side After File Upload Selection

Feb 8, 2011

I have an upload form for an image. The user clicks browse and selects a file. How can I get the image dimensions the moment the user selects the file (before the file is even uploaded to the server). It obviously has to be something client-side with maybe javascript/jquery or flash/flex (prefer js//jquery though), but can either of them do this? This is the code I'm using to tie into zozo's getImgSize() function, but it gives me 0*0 as size.

Php :: Linux - SWFUpload Image Upload Fails With 'Partial File Uploaded'?

Nov 4, 2011

I'm using SWFUpload to upload images without reloading the page (with a fancy progressbar too), this works fine when I'm on localhost (Wamp server), but it goes nuts when I try to do so on my real linux server (which is the only possible flag as far as I could see), it's running Apache2 and PHP5. As I said the front-end is fine (apart maybe from the fact it's flash).The back-end code is as follows:

SWFUpload_settings.js
var swfu_settings ={upload_url : "upload.php",
flash_url : "flash/swfupload.swf",
button_placeholder_id : "upload_flash",

[code]...

The only error that I get is from $_FILES['Filedata']['error'] = 3, 'Only part of the file was uploaded'. The destination directory does have 777 permission and you can see I made the required checks. It simply will not work, I have no idea why. Also, the files I tried uploading had no spaces in the filename, so that shouldn't fit under the issue 206 with SWFUpload.As far as I can tell it can be either due to the front-end SWFUpload or back-end server configuration.

P.S. no need to mention security, this is only allowed to be used by the server admin with external access anyhow, plus there's the front-end limitation on the files he can select (images). There was no point securing it further.

Java - Upload Image Thumbnail To Server Without Uploading Whole Image?

Aug 27, 2009

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?

Python :: Flex Mxml File Being Run On Server As Swf / Html File Be Made Non Cachable?

Apr 28, 2011

I have a application developed in flex deployed on server. In the application data is filled by user and saved in cookies so as to be available even when the user closes the application. However if new version of application is released the user can still access the older version saved in the cahe. How can it be assured that whenever a new version of application is released the application is loaded from the server and not from the cache and at the same time data saved in the older version (in cookies) can also be accessed in the new version.

Flex :: Buttons And Styles - Creating A SWF File Using A MXML File

Aug 11, 2009

I am creating a SWF file using a MXML file. The MXML file define several MX:Button and uses an external stylesheet to style them. There is a problem I am facing at the moment, I am aiming to style the buttons in a way that is similar to the way I can style HTML button elements. However, I could not achieve such look and feel. For example, I could not find a way to define the color and thickness of the borders for each side of the button (top, bottom, left, right), the background color, the margins, the padding, the width, and the height of the button. Also, selector such as hover, active, focus are not available. I was only able to change the size and the font color of the button successfully.

Xml - Sending Data From MXML File To JSP File (and Receiving) Using HTTPservice?

Jul 9, 2011

I want to retrieve data from a Database and display inside a datagrid in a Flex web application. The way I'm thinking of doing it is :

Send the Query data from .mxml file to the .jsp page using HTTPService. In the .jsp, connect to the database and retrieve the data using select statements. send the results back to the .mxml using HTTPService.

I know what to use but I have an ambiguity. In the (.mxml) I use xxx.send() to send the data. What do I use in the (.jsp) to send it back ? I know that I should store the results in an XML in the .jsp file, but how to do that ?

Javascript :: Flash Library For File Upload With File Size Limit And Progress Bar?

Jan 13, 2012

Is there any "mainstream" library used for this purpose? Commonly spread, well maintained, documented etc.I found these (using flash):

Uploadify - not many releases, latest 12/2010, no documentation (!)
SWFUpload - latest release 03/2010, documentation
fancyupload - looks buggy.

phpfileuploader - looks heavyweight, and looks commercial (?) I cannot read the licence (you can download it but are you allowed to use it forever without paying?) plupload New version of pure javascript (no flash) Valums' ajax upload claims to handle file size limit and progress bar, which is quite suspicious to me: these features require to guess the file size before the upload, which seems impossible in javascript (look also here). Or can it work?

I'm at that awkward point in Flash authoring where I know the basics, have tackled only a few of the intermediate issues, and have been assigned a task that seems a bit daunting. I did my fair share of googlin, and searching on these forums and haven't found what I'm looking for.I've created a simple drawing program in flash before, but what I need to add is the functionality to upload a user image and crop/resize it. Does anyone here have a link to an article that will explain a bit about flash's jpg manipulation abilities?
