How to select and process a file in a browser without uploading

I'm trying to find the simplest way to select a file from the local file system, load it into Flex (not Air) application, process it on the client side (without sending it to server), and display the results. It doesn't seem that I can use FileReference for that.
Any alternatives/workarounds ?
Thanks.

... and nonsense one: build small AIR app which will pass selected file contents to the browser via local connection.
AND totally crazy way
1. Load file content using Java applet http://www.captain.at/programming/java/
2. Pass the content to JavaScript
3. Get the content from JavaScript using FP ExternalInterface
Beware! But you'll need a sertificate for your signed Java applet accepted by the user in order to access local file system.

File Lock - How to lock and unlock a file ? Can we do that for an FTP File?

Hi All,
I like to retrieve a file from the FTP server using Apache Commons Net libraries.
for example if the file size is 20MB. When the file is in the progress of copying or transferring from the FTP server i need to lock the local file which is in our local directory so that no other process will use the same local file which is in the process of copying otherwise partially copied files will be used by another process.
the file should be locked when it was in the progress of copying from the server. I have an automatic process which will access file objects at certain time and try to process the files.
I like to know the simplest and easiest way to lock and unlock a file object locally which is trying to copy a file from the FTP server which is of huge size.
And also i like to know how to lock and unlock a file in general?
Thanks,
J.Kathir

we can set it read only only when it complete finishing the writing.
can we able to make the file as read-only while transferring data to file.
How to achieve it ? pls give me some sample code

How to render and save a file as windows media file or mp3?

I have worked in Sony Vegas 9 and I was hoping Adobe Premier Pro CC was similar--- but its not. I can't figure out how to render and save a file as a windows media or mp3 or in any format for that matter.

Search for exporting in the help file
Not all for PProCC, but The PPro/Encore tutorial list in message #3 http://forums.adobe.com/message/2276578 may also help, with more help in message #5

How to select and store the dynamically clicked values in the checkboxes?

Hi Gurus
How to select and store the dynamically clicked values in the checkboxes?
Scenario:-
I am having a tree structure but I am not getting that user has clicked the which nodes.
So how to do it.
Pls.

Hi,
Once again, this is dependent on what your implementation expects. It would seem that your implementation is expecting all of the API to be coded in Java Card so it would make sense that you would load these packages like any other package. Loading an applet is not a special case, it just has an extra step of installing instances of it (and can actually be installed). Any other Java package just needs to be loaded. As such, just load your CAP files for each package of the API before loading any code that depends on it.
Cheers,
Shane

How much ram and processing power in my imac will meet my graphic design needs?

Hi,
I'm in the market for a new imac. I'm trying to figure out how much ram I'll need and which processor will be sufficient for my graphic design needs.
I'm gonna need it to be robust enough to have InDesign, Photoshop, and Illustrator open at once along with spotify, safari with many tabs open, and a couple other apps including evernote and game from time to time. Also, I'm gonna be managing a good deal of fonts in font explorer. How much ram and processing power will I need in my imac to keep everything snappy with all these apps going at the same time?
Any advice on this would be much appreciated. Feel free to include any other relevant information you think I should know.
Thanks, Nick

Computers are out of date when you open the box
Ok, getting serious, that iMac should be a viable workhorse for what you want for a good five years, and taht depends on how much ram you put in it, add really fast external storage, and so on.
Didn't throw this in earlier so as to not influence the discussion: my daughter is the senior art director, VP, at a graphics design firm in NYC. Has been in the business for a number of years. When she changed out her Mac at work, bought, or company bought, the 27" iMac model just before the latest, with maxed out CPU/GPU, and storage. They maxed the memory to 32 GB for her, then added a 30" Apple cinema display so she has almost 5' of display in front of her. There is nothing she cannot have open all spread across that display area. She works almost exclusively in print media, occassionally condescends to do web stuff. And has a massive array of RAID drives hanging on it. But that is a setup an individual would be hard pressed to go with.
At home she uses a MacBook Pro with top cpu and display but that is all.
The point, just how massive do you want to go depends on how fast you have to work; in the office where time is money you need tons of horsepower. At home, you scale it to your abilitty to juggle other tasks at the same time.
I think your choices have been great, the discussion has focused on what is important and especially what can and cannot be changed in the future.
Best of luck setting this up.

How to streamline and remove duplicate files on my HD before I backup?

How to streamline and remove duplicate files on my HD before I backup?
is there a good program or freeware that can automate and isolate when I have
duplicate files hiding in the many folders on my Drive... Yes, in a perfect world
I should know better than having a Drive that is not perfectly organized
I think there is something called SpringCleaning for windows
is there something like this for Mac?
Time machine won't let you remove something after you realized you backed
up two of the same files... Thanks for ideas

You should back up your drive with Time Machine before you delete any files in case you make a mistake.
Tidy Up! - 1.3.2

Click on the Time Machine browser icon on the dock. Locate the duplicate file you wish to delete and highlight it. Click on the button with the gear on and choose Delete "all backups of".

I have files in my iTunes media folder that somehow are not in my library. How do I get iTunes to scan my media folder and add missing files to my library without making a copy of each file in the same location?

I have files in my iTunes media folder that somehow are not in my library. How do I get iTunes to scan my media folder and add missing files to my library without making a copy of each file in the same location? If I use add file / folder to library, it scans the folder and then makes a copy of any file that is not in my library in the exact same location; I recal in older versions of iTunes being able to just drag my media folder into my library and it would update missing links.

Only the songs that are connected to iTunes will be copied when you consolidate to a new folder.
Splitting the media folder away from the usual location makes it harder to move iTunes in the future.
Are you go move everything back once you've tidied up or are you going to leave it that way? Either way I'd recommend you create an iTunes folder at the new location, an iTunes Media folder inside that, and consolidate to this new iTunes Media folder. You should also use the option File > LIbrary > Organize Library > Rearrange files in the folder "<Media Folder"> if you have not already done so.

How to embed and launch ipa file from another ipa package created using Air for iOS

Hi Guys,
Anybody out there knowing how to embed and launch ipa file from another ipa package created using Air for iOS ?

What do you mean by "where to put them" ? What do you want to put anywhere ?
Have you read Peter's comment in brackets ? Perhaps you have a classpath problem ?

How to create and sign CAB files info on Supplement Option

To all Supplement Option subscribers:
At the supplement option for iDevelopment Accelerators, I uploaded a zip with detailed info on how to create and sign CAB files (necessary when you are running your application on the Native IE Java Virtual Machine).
Not all functionality provided to you through JInitiator will work (e.g. WebUtil doesn't) but the way how to make and sign a CAB file will become more easy.

This defeats the purpose of trying to centralize SAP-related web resources on the SAP server. Typically IIS/Apache or other non-SAP servers are under the control of IT and not the SAP BASIS group.
We simply would like to have a centralized location to store static web files so that they are not overwritten during Portal support pack applications.

Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.

How to select and print calls only made and receiv...

how to select and print out list of calls made and received for the past year, between myseld and one particular contact

While I'm not sure about what you want to accomplish, I'll offer a couple of possible solutions.
1. If the items that you want to remove are on the timeline, and those items are in layers that contain no content that you want to keep, then you can just select those layers and delete them.
2. If you want to remove some items from the stage, but keep the original items for some later purpose, just copy the movie and then edit the copy as in item 1.
3. If you need to remove some items from stage and then resize the stage to compensate for the loss of these items, then you may have to move and/or resize some of the items in your movie. This may be as simple as using the "edit multiple frames" selection in the timeline, or it may be much more time consuming.
