Does Air allow file downloads/transfers to desktop from inside app?
Hello,
I am looking into writing an air application that I intend to put onto a usb thumb drive. If a Mac or Pc user plugged the said usb drive into their computer, would the user of the app be able to easily download/transfer files directly onto their desktop from the app with a push of a button?
Secondly, would I be able to display a progress bar showing how much time is left in the download/transfer?
Lastly, if Air is bad choice for this, does anybody have any other recomendations?
Thank you all in advance!
Yes if you build your app with captive runtime you can put it on a thumb drive and copy anything anywhere you want.
You cannot get the progress of any given file's copyTo(), it does not support that event. However if you have lots of files, you could simply count them and average. The progress bar won't be compeltely accurate, but even on the native OS those progress bars are always wrong. (like windows knows how long that folder copy is really going to take...) You could also try to do something tricky like use File.download() from a URLRequest built on file://, but I'm not sure it would work. If you played around with it, you probalby could.
If you have enough files, just count the files and make the progress bar be a % of the number of files transferred.
Also remember to copyToAsync() so that it runs in the background and your progress bar is smooth.
EDIT: please note that a captive runtime will be windows or mac specific (and wont run at all on linux). As a result if you need to give your thumb drive to people with both OS's you'll have to bulid your application twice. Also you'll have to have access to both a windows machine and a mac to do that, since you cannot publish for mac on windows and vice-versa.

I have tried to download the podcast "Ab Trimmer" from Exercise Tv and it does not allow the download to be completed. Comes up with Unable to Download podcast prompt. I now just want this to be removed from my download list, how do I do this?
The fix was to completely remove all Apple Software following guides in previous posts.
Then download and re-install latest iTunes 64-bit, making sure to Run As Administrator.
This fixed it. Now the next thing seems to be that as I move from one device to another to close and restart iTunes between each one. Treat it gently. It seems to break easily and a lot. -
Have some problems to buy/ download Splashtop Remote Desktop from AppStore
Hello,
Have some problems to buy/ download Splashtop Remote Desktop form the App Store.
I receive a message saying something like "Product distributior file could not be found or is corrupt" (translated from german to english).
Can somebody give me some advice how to solve this. I would like to buy, seems to be a nice small app.
Thanks in advance.
BR,
BraVukOk.. let's try something else.
Installing the OS X Lion Update 10.7.3 (Client Combo) reinstalls the App Store for you which may help.
Restart your Mac then try re downloading the app.
How to re download apps from the Mac App Store:
Open the App Store. From the menu bar click Store > Sign In
Click Purchases from the top of the App Store window.
Select which apps you want to re download. Then right or control click where you see Installed then click Install.
Make sure and use the same Apple ID used for the original purchase.

I downloaded the mountain lion from the app store and it downloaded. When i installed the mountain lion it said that the hd disk is broken and cannot be repaired, and the other disk doesnt have enough space! HELP and i cannot return to my desktop with the old sofware so i cant use my computer normaly
This error means that your hard drive is badly corrupt and cannot be repaired by Disk Utility. Since you say you don't have backups, this is very bad news. You may already have lost data irrevocably.
First order of business needs to be backing up whatever you can, but this may be difficult to do if the machine won't start up any more. See step 1 of the following post:
https://discussions.apple.com/message/21614450#21614450
Once you have backed up your data, you can address the other issues. -

Iv downloaded the 0845 wizard from the App Store. Registered my details and it has been working. But for some reason it won't let me log in and keep saying failed every time I try to use it. Iv deleted and re-downloaded the app and it still says the same?
I would say to start by looking on their web site... unfortunately, that appears to be dead.
Based on the horrible ratings on the App Store (1 star for the current version), I'm not surprised it doesn't work well. -
After upgrading to Yosemite I have lost iPhoto. It has a cross through it in Finder, but I clicked on it and I was directed to download the latest version from the App store, but it is not available in the Australian store. Can anyone please help? I am not an advanced user and I would like my photos back, having had no idea I would lose iPhoto in the upgrade!
Thanks petermac87...but for some reason, the only purchases showing are OS. So assuming iPhoto is in Mountain Lion, I was hoping to look under Hidden Items there as you suggested, but there is no option for that. Only option is to download Mountain Lion again, not iPhoto specifically. Any ideas welcome!

Cannot download Final Cut Pro from the app store
Hello,
I cannot download Final Cut Pro from the app store.
I says "Failed to download" and error has occurred
What is wrong?
is it my Macbook?I had a problem way back in the olden days, i.e., FCPX 10.0.2, and finally gave up and called the Apple Store using a land-line phone.
Anyway, (this was a couple years ago), if I remember right, they passed me off to someone in the FCPX group and I got the App. However, this was not a really goo way to go because for many updates afterward, everytime I wanted to update I had to go thorugh the same ritual.
Finally, probably around 10.0.8, things got "fixed" and since then I've been able to go direct and download it from the App Store without having to make a phone call.
My suggestion would be to try calling the App Store. Maybe, if there is a "global problem" and they get a lot of calls, they will fix it.
Heck, maybe write a Knowlede Base (KB) article about it.
Disclaimer: I didn't check to see if there was one.
