Drag and Drop for File Uploads

Hey,
Is it possible to do this in Flex? Drag and Drop files into a flex app - to upload them later (say on a button click). I did some searching and found that it is possible to do this in AIR - drag files from the file system and drop it in the app. But our app is web based and will be running in a browser.
Thanks

I have suffered from this during the past three days.
Firefox 23.0, Mozilla Firefox for Ubuntu canonical - 1.0
on a 32-bit Ubuntu PC. So the system couldn't be more different.
I was trying to upload .MP3 files of 27MB. From about a dozen attempts with one file, no success whatever. On the other hand a different file worked first time. But a later attempt with a 14 MB .wav failed, so it's not related to the file.
On the other hand an upload with Chrome worked perfectly. So it does look like a browser problem.
Watching the system monitor during upload, it runs freely for about 9MB, then stops abruptly. At the same time, the message at the bottom left of the browser window, relating to dl-web.dropbox, disappears.
The text of the message differed between Firefox & Chrome, but I imagine that's just a textual, rather than a functional, difference.

After upgrade to Yosemite, drag and drop for files does not work, destination folder crashes.

After upgrading to Yosemite, dragging and dropping files from one location to the destination folder, causes the destination folder crash. However, copying the file and then moving it works fine.
I'm not sure where to report bugs, but I figured this would be the best option

Drag and Drop for iTunesU uploads?

Are there any tools that use the APIs to allow easier uploading of content to iTunesU sites than what iTunes currently allows?
We have a number of Marantz devices that record the podcasts and it would be convenient to be able to just drag them to where they need to go versus having to navigate to each site, then browse / upload / etc.
Any ideas on this?

Can anyone help me to figure out the if/else or switch statement to be used? I tried both but it doesn' work. This is my switch statement.
var stage = sym.$(new bigElements) ;
switch (bigElements) {
//list down all the possible cases/scenarios.
case "Stage__2":
          alert("Just like the sky!");
    break;
case "Stage__5":
              alert("Just like shiraz!");
    break;
case "Stage__7":
    alert("Suit yourself then...");
    break;
default:
    alert("lalala...");
var stage = sym.$(new bigElements)
switch (bigElements) {
case "Stage__2":
    alert("Just like the sky!");
    break;
case "Stage__5": //"case2"
   alert("Just like shiraz!");
    break;

   alert("Suit yourself then...");
    break;

     alert("lalala...");

I download firefox 5.0 and now I'm having trouble dragging and dropping PDF files into Google Docs and I can't view the PDF once uploaded. I had no problems with this in the previous verion of Firefox

With firefox 5.0 I can't drag and drop pdf files in the google docs screen. When I do eventually get a pdf file uploaded I can't view it. I get "no preview available". In my previous verion of firefox (4.something) I had no problems with this and I was able to drag and drop and after uploaded I could view the entire file.

Thanks one again. I know you helped me the last to. I do have the Deja Vu font set in my folder. I downloaded and the last time. So I don't know if there is supposed to be more or not, but those were installed with Windows-XP after my reformat.
This is really driving me nuts. as I've done several re-formats on my computer and several friends computers and even upgraded hardware so I am not necessarily a software or programming expert, I am somewhat advanced when it comes to computers in general and can usually diagnose the problem but these font's are the problem and they never were before.
I did see in another forum that if you had a Dell Computer and did the Microsoft update for the onboard video card driver that it could be the culprit, but I have that disabled being I have a much better graphics card so the updates from Microsoft for the onboard video weren't installed.
It' a Dell Dimension 3000 with an Intel(R) 82865G Graphics Controller so I don't believe it is the culprit being it is disabled. The actual video card that I am using is a PCI Nvidia GeForce 9400 GT with 1 GB Memory. And I didn't have any problem before.
I appreciate the help. But still can't get things to work. Live Help Chat doesn't open for another two hours so maybe they can do "Remote Access" or something and can check setting and help me. But if you come up with other suggestions, they would be greatly appreciated.
Thanks again.

Drag and drop several files

Hi,
I'm using iPhoto '11 (version 9.4.2) and when I try to drag and drop several files into a folder, it fails.
Actually it just does nothing: the drag and drop icon is created with the accurate numbre of items in a red star, the folder blinks but when I release the mouse, nothing happens.
It fails sometimes with 3 photos, sometimes with 30.
What's more puzzling is that it sometimes works: if I drag and drop of a single photo it always works. And I'm sometimes able to drop 10 or more photos.
I'm running on a macbook pro retina with lion (10.8.2).
Any idea of logs I could look at for some informations, some errors messages?
Thanks,
Laurent.

I guess it creates new photos, hence it modifies the timestamps whereas drag and drop does not.
There are two kinds of metadata involved when you consider jpeg or other image file.
One is the file data. This is what the Finder shows. This tells you nothing about the contents of the file, just the File itself.
The problem with File metadata is that it can easily change as the file is moved from place to place or exported, e-mailed, uploaded etc.
Photographs have also got both Exif and IPTC metadata. The date and time that your camera snapped the Photograph is recorded in the Exif metadata. Regardless if what the file date says, this is the actual time recorded by the camera.
Photo applications like iPhoto, Aperture, Lightroom, Picasa, Photoshop etc get their date and time from the Exif metadata.
When you export from iPhoto to the Finder new file is created containing your Photo (and its Exif). The File date is - quite accurately - reported as the date of Export. However, the Photo Date doesn't change.
The problem is that the Finder doesn't work with Exif.
So, your photo has the correct date, and so does the file, but they are different things. To sort on the Photo date you'll need to use a photo app.

i tunes 6 used to be great for me but i upgraded to 7 which wiped my i tunes and ipod. im back to ver 6 now but i cant drag files from my c drive to any playlists

I just downloaded the new version of iTunes 10 and now it won't let me drag and drop any files from my computer.

I just downloaded the new version of iTunes 10 and now it won't let me drag and drop any files from my computer into my iTunes. It lets me play the song from the folder in my computer and then it opens with iTunes and plays the song all the way through, but then if I try to play it again, it says the file cannot be located. So then I go to locate and go to the folder and all that and select it and nothing happens.

Not sure whether for instance you initially had a Yahoo optimised version of Firefox, and have now overwritten it with an official Mozilla version. Although the Mozilla version should NOT add unwanted features, but the Yahoo version may well do.
If you merely need to find the Yahoo emails page quickly just add it as a bookmark or as a bookmark on the Bookmarks toolbar and make sure that is visible.
Clicking the star icon on the location bar whilst looking at your emails will bookmark the page.
* [[How to use bookmarks to save and organize your favorite websites]]
* [[Bookmarks Toolbar - Display your favorite websites at the top of the Firefox window]]
I do not use Yahoo myself,and am not sure what add-ons are available. You could search yourself using
* FirefoxButton -> add-ons
** see [[Find and install add-ons to add features to Firefox]]
** examples [https://addons.mozilla.org/en-us/firefox/addon/yahoo-toolbar/ yahoo toolbar] & [https://addons.mozilla.org/en-us/firefox/addon/yahoo-mail-notifier/ mail notifier]

Drag and drop for PC and Tablet issues

Hi!
I’m doing a drag and drop for both PC and tablet.
I need to allow any elements (draggables) to be able to drop into any of the droppable areas and not just restrict to 1 area. I tried using the if/else statement, but I can’t seem to make it work. For example, Position 1 (droppable area) must be accept all the cases – case1, case2, case3 (draggables), but only 1 draggable on a droppable at any one time.
I hope you can help me out, or atleast helping me with the if/else statement.This is a link to my folder.https://www.box.com/s/0pksqtpmqg7zae43en66

This appears to be a long-standing bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=634720
and the accepted workaround is stated in comment 11.
Oddly, it's possible to do the reverse, i.e. drag multiple eml files from Explorer to a TB folder.

Set default import format when drag and drop sound file into multitrack view?

I've looked around the preference panels but cannot find where to set the import settings for dragging and dropping sound files into multitrack view. Some of our computers have correct settings and others do not. Thanks for your help!
G

I should have been more specific, sorry... I mean bit depth and bit rate... On some machines this defaults correctly and on other machines it is wrong. Not sure how to set these to downconvert properly by default. Unless it automatically takes the format of the source file, in which case it's just been luck.
Thanks,
G

Can't drag and drop music files

after recent update i can't drag and drop mp3 files into library like before or go file->add file to library

Thanks for the quick response Sebastian.
Yeah, I know I can find the file in finder, but I used to be able to organize all my files in the iTunes interface and easily drag them to my project in AE CS3... so much more convenient.
I tried .aif and .wav files, all formats that AE accepts. Like I mentioned, I used to do this with AE CS3 and my Windows OS... I was just wondering if this was a Mac bug or something. Not the end of the world, but it's little things like this I waste half a day on trying to figure out!! lol.
