I need to save a file in Flash without a prompt; what my program does is it gets all the frames from the stage and then it saves them as png files, along with a text file that has the name of the object, and some other properties about it. The code that I have does save it without any problems, but I need it to not prompt me, because I have lots of frames to do this with.
Is there a way to do this with Flash the program or actionscript?
No, unless you're using Adobe AIR. The reason for this is Flash Player and its programs are generally run through a browser over the Internet, and if people could use Flash Player to just start saving files on other people's computers, there would be some very serious security issues. AIR, on the other hand, is generally run on a desktop, laptop, or mobile device, and its programs are run directly off the same, having been pre-installed. So whereas a website can suddenly just start running a script with Flash Player without asking you first, AIR requires you to have already installed the script/program on your computer, meaning that it should be there intentionally. So security restrictions are lighter, enabling the use of the File class in your programs.
The only way to save a local file with the Flash Player (in the browser) is with FileReference and it will always prompt the user.
However, using AIR (desktop or mobile app) you can save to the local file system without user input, using File and FileStream. You can create an AIR app using Flash Pro, usually without any code changes other than the AIR APIs you need (flash.filesystem in this case).
Another idea, if you must use Flash Player and not AIR, is to first zip all the PNGs and only save to file after they are all packaged. This way there's only one file and prompt to save.

It is an ancient binary file extension, actually a video file created by Inter-Tel Web Conference software. It contains a screen recording video and voice audio, and also can capture the keyboard chat log, attendees and the document manager window during a conference. It can be played with Inter-Tel Collaboration Player, a standalone application included with the Web Conference software package.
What I am trying to do now is finding a way to play these files on mobile, although Inter-Tel Collaboration Player offers exporting the files in AVI format, I want to know how to make a command line script for that because the application have lots of problems with Windows 7,8,10 and don't have a Mac OS version.
What is the way to create a new player for that kind of extensions?
"Linktivity stopped support on this app, http://linktivity.com even disappeared from the web..."
It seems they were bought out by Mitel Software so now everything is under the Mitel brand name.
"I just want to find a way to manipulate this file extension, a new good player for mobile and computer"
To open/edit those .lrec files with modern software you'll have to look at their :
Collaboration products.
Unified Communication products.
I tried :
To contact them just to double-check facts but they expect a realtime phone conversation with a salesperson so it wasn't an option. I'd be a fake potential customer, but you can provide a real-world issue (with background details) to see if they can solve it.
Also downloaded for Android the MiCollab app but it needs login details before even starting anything (so no progress to just check if an .lrec file from PC would open within Android).
Export videos for mobile playback :
I've tried the desktop software. Unfortunately it does not accept external commands so there is no way to make a script that takes multiple lrecs and gives back multiple AVI.
The only option is to extract frames from .lrec bytes and use a tool like FFmpeg to combine the images (since appears to do image grabs as frames) into one .MP4 video. MP4 is then playable on mobile devices.
Also any of your existing AVI files should be converted with FFmpeg to MP4.
You can download FFmpeg for Windows here (just the big blue button, ignore other options).
Copy the ffmpeg.exe file to some folder like c:\ffmpeg and put your avi's there.
Now open Command prompt and do cd C:\ffmpeg to reach folder, then type : ffmpeg -i filename.avi filename.mp4 (replace filename with preferred for input and output)
If you know how, just include ffmpeg.exe path to Control Panel PATH settings so that FFmpeg can be accessed from any folder (no need to move files to its own folder).
PS:
I am still researching how to get the frames it's an akward format without the specs (bytes order is Big Endian but then entry values are filled as Little Endian, then also not sure whether to reverse every two or four bytes cos it's mixed up like that etc and the pixel bytes themselves seem to have compression but it's not JPEG more like ZIP or whatever). Only confirmed bytes so far are for video width and video height. It seems doable though if the .lrec only contains screen recordings.
After some research, I found that Media Player Classic can play .lrec files. I don't know, if this helps you a bit.
For a own video player for your company, you would need the encoding infos or a decoder directly from Inter-Tel since they own the licences, without it you can't create one.

I'm trying to save some screen dumps to internal storage for debugging purposes, but I can't seem to get access to them. When I call FileSystemStorage.getInstance().getAppHomePath(), I get a path that looks something like this:
/data/data/com.mycompany.myapp/files/
But I can't see this folder in the Android File Transfer tool, so I can't drag the files to my Mac. I also tried attaching them to an email using the Message class, but for some reason the attachments never showed up. I notice that a lot of applications store data in folders like this:
/Android/data/com.doubletwist.androidplayer/
If I try to create a folder like this, I run into two problems. First, it's not platform independent. (This doesn't matter much because I'm just doing this for debugging.) Second, it doesn't work. I get an error telling me I need to use the directory returned by FileSystemStorage.getInstance().getAppHomePath()
Is there any way I can save files to a folder that I can actually retrieve them from? It would be more helpful if I had a platform-independent way, but any way that works is fine for now.
File system is a very "unportable" notion. By default app home is a private folder which some mobile OS's including Android 4+ keep private and inaccessible.
Android has a concept of "sdcard" which used to be a physical storage where you could write anything in any directory without a problem. This is no longer applicable for later versions of Android but you can read from the sdcard directory and detect it.
FileSystemStorage has an API to get roots and their types, if you have an sdcard type you can read from there. You can use the FileTree to see the file hierarchy as exposed to your application which can be useful for debugging.
We have a bootable USB stick that works perfectly. It will boot, ask the user for some options, then write files to the hard drive accordingly. We did this by using rufus-2.1, throwing freedos into the USB stick, and basically hijacking autoexec.bat. Autoexec.bat now executes some separate .bat scripts based on user input.
The problem is, we now want to have an option to allow users to burn an iso to a cd or dvd. We've been trying to create an image of the USB stick and burn it to a DVD.
We found plenty of information on this subject, but nothing has worked. We started by extracting the bootimage from various bootable iso files using imgburn. None of these worked. We tried extracting the bootimage from our USB stick, and that also didn't work.
Next we tried WinImage. We extracted the boot information from boot98.exe, hijacked autoexec.exe, created a new image and injected the files. We saved the files as a bootimage and tried the above method again, which also didn't work.
Is there perhaps a more straightforward way to execute DOS .bat scripts through cd/dvd boot? We'd be open to something other than DOS as well, as long as it can write files to a hard drive based on user input through a simple boot interface.
Note: The computer itself does not contain an operating system.
Thanks.
We found a very slick setup that does what we need. Unfortunately, the CD-ROM drivers do not work properly on modern DVD drives. Using this method, it should be possible to put all the scripts directly in autoexec.bat and run commands directly on the "simulated" floppy drive. For whatever reason, we can boot from the "floppy" section of the CD-ROM, but it cannot copy files from A: to C:. I believe we are very close, but no cigar.

First method that actually produced a bootable CD and allowed scripts to be run by a choice entered by the user.
I have a WPF application that is designed for a touchscreen kiosk. Users will not have access to a keyboard or mouse. The application runs fine when started normally from the program icon in windows. However, when it is set up to run automatically at startup (by replacing the Windows shell using a registry key), the application does not function properly.
The application reads an XML file that lists available videos, then displays buttons to show the videos. When run in "kiosk mode," it does not seem to have access to the files in its media directory (the XML file and presumably the videos as well). I suspect that because the application is running in place of the windows explorer, it is missing resources it needs for file access that are normally loaded by windows explorer.
I have not been able to find any info on this - there is plenty of info on how to get an app to run at startup, but not much on how to make sure it will actually function in that environment. The PC is running Windows 7 Professional.
Is my assumption about the problem correct, or is it likely something else (e.g. permissions - we checked the permissions, but maybe they operate differently when you replace the windows shell?) If it is because needed resources are not loaded, does anyone have pointers on how to make sure my app loads them?
Perhaps you have file access occurring via a file dialog? This might explain a bit further. What is the minimum functionality needed to create Shell Replacement for Windows?
because you have stopped windows default running explorer.exe , your program can not get access to default xml directory therefore you should specify the complete path for example like below:
stream = File.Open(#"C:\x86\Debug\xml.xml", FileMode.OpenOrCreate);
I've become familiar with the new concept of "out of browser" web applications, supported in the recent Silverlight, JavaFX, Adobe AIR etc.
Listening recently to a podcast on the subject by Scott Hanselman, I've become aware that one of the purposes behind these new architectures is to allow for "desktop-application-feel". Also, I understand some (or all) of these allow for some offline access to a sandbox of resources. This really sounds as if these frameworks could be an alternative to "real" desktop applications, as long as the application does not require messing with the user's machine (i.e. access to peripherals, certain file IO, etc).
I have a very specific question. My application needs to run at start-up. Is it possible to do so using such a framework without requiring the user to download and run a certain executable?
For example, I could always direct the user to download a small EXE that will put a .lnk file in the start-up directory, but I want to avoid such a patch.
To summarize: is it possible to have an out-of-browser web application setup itself to run at start-up without requiring file download?
To further clarify, this question does not come from an "evil" place, but rather from trying to decide whether "out-of-browser" frameworks are indeed a proper alternative to a desktop application, for my specific requirements.
The BkMark example here shows how to start an application on startup using Adobe Air. So, yes it is possible.
So, here's the deal: web apps in general will have a security context around them, and by default won't have access to write to the filesystem (outside of a temp files), access the registry, etc.
One way is, as you said, have the user run something or configure it so the lnk is executed on startup.
Another way, and I think, more in line of what you want, is that the user can run the program himself, click some button in the application, and it's configured.
I know with Java you could do this, but the user has to allow full access to their system, because your app would need to change System configuration. Then you could just configure it (by writing a lnk to your WebStart JNLP in the Startup folder)
For Internet Exploder, Javascript apps do have write access to the disk.
For other (better-secured) browsers you will either need to have a download, or Adobe AIR.
Assuming you are building for Windows, launching an executable at startup can be done several ways.
For user session startup, you can achieve this either by putting a lnk file in the appropriate folder, or with a registry entry. For operating system startup, you can achieve this with a registry entry. There are several permutations:
run application once on boot (UI not allowed)
run application every boot (UI not allowed)
start service every boot according to policy set in registry
run application once on user session start
run application every user session
Since an out of browser application has UI I expect you mean run application every user session and in this case you may as well put an LNK file in the user's startup folder.
I just created a shortcut for an SL4 OOB application, and this was the Target of the shortcut:
"C:\Program Files (x86)\Microsoft Silverlight\sllauncher.exe" 2635882436.localhost
A search of my disk revealed that location 2635882436.localhost is a folder.
C:\Users\<mylogin>\AppData\LocalLow\Microsoft\Silverlight\OutOfBrowser\2635882436.localhost
I rather doubt an OOB app of any type could place a shortcut in the Startup folder unless you somehow obtained Full Trust.
