In flex when I allow user to download a file using :
dwFile = new FileReference();
dwFile.download(downloadURL, dwFileName);
Is there a way to ensure that the downloaded file always ends up with the extension .tar or any other extension for that matter? By default I give it a name like xyz.tar, but as of now the user can tamper with filename, including its extension. Can I prevent him from doing so?
I made an AIR application that parses some specific files. I am using flex builder 4.5 and SDK 3.6. I want to attach Icons with those files and when I double click those files they should open with my application. How can I do this?
View 2 RepliesI have a mp3 that is retrieved from the server via "somepage.php?id=100". When I load this into spark VideoPlayer it doesn't work. But when I copy that URL and put it into the browser URL I get a dialog that asks if I want to download "sound.mp3".
UPDATE!!!
// in the creation complete handler
var audioElement:AudioElement = new AudioElement();
audioElement.resource = new URLResource(path);
[Code]....
It seems the audio is cued up in order when added to the creation complete meaning that if one audio file is loading another will not start until after the first has completed.
Is there any way to determine a file type from a url when the file extension is not a reliable indicator? Since there are different APIs for playing video, audio, or displaying images, you need to know the filetype beforehand.

View 1 RepliesWe used Flex to build the web app below. It lets the user build an interactive activity and click "Publish as Flash" to save a SWF file on their local computer.[url]...
Problem:When saving the file, the "Save As Filetype" drop down is empty and end users can accidentally delete the swf file extension in the filename.How can we lock down the extension so it will always have SWF in the extension?
Technique 1? Set "Save As Filetype" to SWF by default.
Technique 2? Click "Publish as Flash". User specifies the filename. File is saved on the server. User presented with prompt to download file. File is downloaded from the server using the traditional browser windows explorer dialog box (the same dialog box if I downloaded a program from cnet's downloads.com)

Is there way to set the extension of a file using Adobe Air's flash.filesystem? Using the browseForOpen function you can set the FileFilter, limiting the files types available. However when using browseForSave you can not set a fileFilter or fileExtension. The file extension has to be entered manually in the SaveFileDialog. The File.extension property associated with the selected file is read-only. Does anyone know of a work around or anything that I could do to not enter the file Extension manually.

I need to lock off access to any .fla files that might come up on a virtual host. We keep them next to the few .swf we use on some of our sites, I just want to be sure they are not being downloaded by people or spiders that may scrape the site.
There isn't really anything sensitive in the fla's but I'd rather keep them in the same folder and have them forbidden to downloaders.
I've tried the MIME type route (check if MIME type is defined under HTTP Headers > MIME Types, remove if it was, etc;), but there is no FLA defined, but I can still download the file by default. I recall this was the opposite if you WANTED to serve .flv files, but not .fla's[code]...
I am uploading videos to my new site (aspirin creative) and the player will not recognize any .f4v videos. I changed the extension on one to .flv and it now appears to recognize and play the video. Also, I didnt build the site myself and the developer not Define terms of video playback (which has been less than great so far) the player seems to be a rather strange resolution (600x340) which is not native 16:9 and wont recognize 4:3 encodes without stretching and warping. I have tried to encode close to this in media encoder but as soon as I select .flv over .f4v in the options my ratios seem to go mad, not keeping the preset and not letting me set to anything that is actually 16:9?!
View 2 RepliesI'm trying to get my flash movie to allow the user to download a file of a specific extension, at the moment i use:
[Code]....
Two problems:
a) If the user changes the file name in the browser before clicking save (and doesn't re-add the .xml extension) then the file is saved without an extension
b) Randomly, tested on two windows xp systems both in IE one included the extension in the filename on the browser download window and one didn't (which doesn't make it clear to the user they have to include the extension as part of the name) but both saved to the correct xml extension file
a) If there is a work around so I can specify the exact file type, in the adobe reference manual it states you can parse in extra parameters to server with the file location to download. How would i do this?
b) If can't do a, how can I get it to always display the extension in the browser download window (unlike in problem b )
Just as title says is there a way to automaticly add extension to file name. when i create a new XML via flash it works but i have to type in the text field name of the file and extension i.e: full.xml, to save the file as xml, and i want to write just the filename and extension is added automatically

During the application run, I set another custom render to the same column.When I scroll data in the grid (change values for the custom renders) they display new view correctly.I want that they dispaly new view automatically (when I set them): so I think I have to call them and tell tham to refresh rgeir views.
View 1 RepliesI've got a small action-script chart, that's meant to be live updating, and also be able to support more than 10000 points of data. The way it's currently set up it doesn't need to redraw the whole chart if the new line we wish to add doesn't extend that chart's boundaries. Yet it does, the redraw regions show the whole chart as being redrawn as opposed to the single line i need to add. When the chart gets a new piece of data from the javascript it does the following.(some stuff has been stripped for clarity.[code] Is there any better way to do that, that won't redraw the whole screen? Is my coding pattern wrong for this type of update?
View 1 RepliesIs there a simple way to force all the child components of a Flex app to redraw when that app is resized?
For instance, I have a HDividedBox with percentHeight and percentWidth set to 100. On the left hand side of the divided box is a data grid and on the right side is a number of text inputs. The divided box is not added to the view stack until after the user logs on.
If I resize the app before the HDividedBox is added then the box takes up the full size of the app, whatever that may be. However if i resize the app after the box appears then the box retains the same dimensions it does when it was first added.
I would have expected that on the resize of the app then all the children would redraw (the application component itself appears to).

I'm wondering what the process would be for importing the filenames of songs minus the .mp3 extension into Flash would be? I want to import the filenames, and then create a for loop that goes through and adds some html tags to each name, and eventually I'll spit out a text file of it all for me to copy and import into a search function on a webpage. I think I can work through the latter, but I was wondering how to originally import the filenames into a swf?
View 5 RepliesI'm using FlowPlayer to replace an existing FLV player on my site that plays videos from Amazon E3. I have many pages and each should show a different video. For each page, I have a value stored in my CMS that is the "streamName". The stream name corresponds to a flashvars paramenter in the object/embed tags that show the video player:&streamName=my-great-video
On my new player, I'm able to get the video using a URL similar to [URL] How Does Flash (or Amazon???) know to add in the .swf extension? There are several video formats used on the site, and the current player works with them all... But, as I mentioned above, on each page the value store for the video (ex="my-great-video") includes no extension.
I have a ProgressBar in MANUAL mode responding an URLLoader's progress events that seems to get drawn far less frequently than I would like. If I debug the app, I can see many events firing from the URLLoader yet it seems that the ProgressBar is being re-drawn at some random and slow rate.
Now if this was my own code (URLLoader is a black box), I would pause once in a while to let the UI update, say via loop with a timer. I presume that the URLLoader itself is blocking the main thread from processing drawing code. Adding validateNow() and invalidateDisplayList() does not seem to help much.
private function onLoadProgress(resource: TResource, evt: ProgressEvent): void
{
_progressDialog.prbCurrentItem.setProgress(evt.bytesLoaded, evt.bytesTotal);
_progressDialog.prbCurrentItem.validateNow();
_progressDialog.prbCurrentItem.invalidateDisplayList();
}
Now there are many TResources (just a class that can manage its data) being loaded in sequence, but the URLLoader is so greedy that it does not let the UI get updated more than a few times when loading & processing (parsing into XML objects) 50 or so 10KB files. So just counting which files loaded visually does not work either; I'm lucky to get 2-3 screen updates the entire time.
Loading a 700MB file looks much better, but again the progress bar updates are random and slow.
Additionally, I'd like to know if there is any way to influence or even control the rate at which ProgressEvents are fired by the URLLoader class. I have not been able to find at what rate it normally dispatches progress events either; is it at a fixed percentage per file or every x frames or milliseconds?
As these are local files, would I be better off not using the URLLoader class and instead switching to FileStream?
handling global keyboard events in Flex, is to attach a listener in the application complete event of a Flex application. However, no matter what I try, I have not been able to catch events without clicking on a point on the page, which is hosting my Flex application.
Moreoever, if I use a Flex component in a web application, where there is also html and Javascript, I'd still like to be able to grap global keyboard events, even if the embedded flex component (in flash player) does not have focus. So is there a reliable method for connecting flex applications and components (when they're embedded in a web page) to keyboard events?
For example I've got string /wiki/File:test.JPG I should check if it has one of extention "jpeg","jpg","png","gif"

I'm trying to make an existing FLEX application section-508-compliant, by getting it to work smoothly with the JAWS screen reader. It kinda sorta works, but one immediate problem is that when you first go to the login screen, your cursor ends up in the userid field, but JAWS doesn't read anything useful (like the label of the field you're in!) until you hit TAB or something. Is there a way to force it to speak immediately on application startup, without making the user tab/backtab just to hear where they are?
For that matter, as cool as it is that it reads interactive controls as the user tabs around, sometimes you just need to make JAWS say something at a particular point in the logic, which might or might not be associated with a conrol... as if you could write AS code like "jaws.speak('');".
I need user download JPEG file from my app, however, when user change the file name the saved file will be downloaded without extension.
For Example: I am using FileReference.download() and set the default filename as "demoPic.jpg" and user's windows system setting control file extension not being shown. So when the dialog opens a download window, only "demoPic" shown as the filename. If user saved file without changing filename, the saved file will be OK. But if user change file name, the download file will be saved without extension. is it possible to add file extension to filename when user forget it by flex code?
I have a flex app, which I want to embed into a Mediawiki, preferably. in the form of an extension.
View 1 RepliesI'm working (for my sins) on a Flex 3.3 project, which unfortunately cannot be upgraded to a newer SDK version at this stage, and have hit an issue with the custom hierarchical tree class (subclassing mx.controls.Tree) we're using. Excuse the spelling; the previous developer had a fear of dictionaries...
public class HierachyTree extends Tree
public function HierachyTree()
{[code].....
I'm using a solution somewhere between these two methods (basically, implementing ITreeDataDescriptor) in order to add live text filtering to the component, and it's working so far:
public class HierachyTreeFilteredDataDescriptor implements ITreeDataDescriptor
{
private var filter:Function[code]..........
The issue is that (with tree:HierachyTree) neither tree.maxVerticalScrollPosition nor the protected property tree.verticalScrollBar .maxScrollPosition updates when the search string is changed.I've tried calling invalidateList() and invalidateDisplayList() on tree — and calling invalidateDisplayList() and invalidateSize() on tree.verticalScrollBar — to no avail.
