Javascript protect pdf from being copied or to stop the file being opened after a particular date.

Hi,
I need to find out if there is a possible way to keep a check on a PDF so that it can become unsuable after some days of being opened first or anyway to make the file content uncopyable . Any javascript for the same.
Thanks
Kapil

In all practical senses, no.
While it is possible to fake security using JavaScript (for example by showing or hiding an overlay on each page) it is trivial to defeat, and will not work in third-party PDF viewers such as OS X Preview, Chrome or Firefox. Embedded scripts cannot change the protection on a file to enable or disable the copying of content.
The only way to 'expire' a document is to use digital rights management through the Adobe LiveCycle Rights Management server product.

HT4059 I used to be able to transfer PDFs from Dropbox to iBooks but now the file appears for about 1 second and then disappears - any ideas?

Can anyone help? I want to transfer PDF files from Dropbox to iBooks but when I do, the file appears for about 1 second then disappears. I used to Beatle to do this with no problems, but now it doesn't work. Help!

I had the same problem. After numerous attemps to Restore from Itunes, I decided to use the "Setup as New Ipad" option. It went through a few question on new setups. Afterwards all my apps, data, photo's were still intact. Which shows that the Restore from Itunes worked. There must be a small bug that prevents the Ipad to open after "Restore from Itunes" . Hope it will help you.

When i select a pdf file for download in a webpage instead of automatically downloading the file and opening it using adobe acrobat I get a new blank window in the browser and it says done in the bottom left corner

when I select a pdf file within a webpage and click to download instead of getting the "download" window and the file automatically opening after download using adobe reader I get a blank webpage (in the same tab) and in the bottom left corner it says"done". No file is downloaded and if I click "back" I just return to the webpage containing the link.

Aha! The properties for the plugin file nppdf32.dll for Adobe Reader indicate the file is for Adobe Acrobat. This misidentification is then used by SeaMonkey as a label in the helper application list.
Adobe Reader 11.0.3.37: nppdf32.dll has version 11.0.3.37. This is the version in SeaMonkey's plugins folder.
Adobe Acrobat 7.0.8.218: nppdf32.dll has version 7.0.9.50.
As for having both Adobe Reader and Adobe Acrobat on the same PC, this generally works providing Reader is installed AFTER Acrobat. Reader is freeware, and I want to keep it current. Acrobat is purchaseware, and I cannot afford to keep buying upgrades or newer versions.

How do i protect pdf from being forwarded by email?

There's nothing at all you can do to stop a PDF from being copied, emailed, put in a USB stick, uploaded to DropBox, or shared in any other way. DRM ($$$$) can make it so that unauthorized copies cannot be opened.

This may help, but I do note that the printer you state is NOT on the airprint list. You may need to go to the app store and see if Canon has an app that will facilitate printing on a non AirPrint device.

How can i open a PDF bank statement in numbers so that the rows and columns contain properly aligned data from statement?

how can i open a PDF bank statement in "numbers" so that the rows and columns contain properly aligned data from statement?

Numbers can store pdfs pages or clippings but does not directly open pdf files. To get the bank statement into Numbers as a table I would open the bank statment in Preview (or Skim) or some pdf viewer.
Then hold the option key while selecting a column of data.
Then copy
Then switch to numbers and paste the column into a table
Then repeat for the other columns in the pdf document
It would be easier (in my opinion) to download the QFX or CSV version from your bank

My computer crashed. So does this mean I can not add any more music to my ipod from a different computer without all the songs being erased? Can I sync my ipod to a new computer if I allow all the songs to be erased?

My computer crashed. So does this mean I can not add any more music to my ipod from a different computer without all the songs being erased? The ipod works fine and now i got a new computer. So it seems like my only options are leaving my ipod in a state where i cant add anymore songs or erasing all my songs and trying to use my ipod from my new computer. Can someone please inform me on how to have my ipod work from a different computer, even if i have to erase my songs. Thanks.

Yes, if you choose the Erase and Sync option (or restore your iPod) you will be allowed to sync your iPod with the new computer.
If you would like to save the content that's currently on your iPod, see this older thread from another forum member Zevoneer discussing the different ways to copy the content on an iPod back to your PC.

Cannot save as PDF - "Could not save a copy as (filename) because the file is already in use..."

I have a number of PSD files I've created and I'm trying to save them as PDFs.
I can Save for Web and Devices, I can save as a .gif, .eps., and every other format I've tested, but I cannot save as a PDF. I get the error:
"Could not save a copy as (filename) because the file is already in use or was left open by another application."
I'm running Adobe Master Collection CS5 with Photoshop CS 5.5 (12.0.4 x64) on a Windows 7 64-bit machine.
I have a 928 GB HD with 697 GB free.
I have rebooted and tried saving the files immediately after I reboot. I have killed my virus scanner. I have killed a number of other possible culprits including Acrotray.exe and CS5ServiceManager.ext
I have run Process Explorer as recommended by Microsoft and found no applications using the file. I've also tried saving the file to my external hard drive and/or renaming the file with only rare luck.
Nothing seems to fix it.
The boards seem to suggest Adobe isn't taking responsibility for this and pointing it back to the OS or other software. I'm willing to believe them if someone can show me how/where to kill whatever process it is - but at this point, all my indicators point back to Photoshop.

Here is a clip from a past post where user could not drag and drop files to hard drive.
To my great relief I have now sorted this issue and offer the following as the Correct Answer. My sincere and grateful thanks go to Curt and Yammer, above, who have helped me so much in sorting this Windows 7 issue which is clearly very relevant to Bridge users also. Any slowness to grasp what they have been saying is down to me!
The key to solving this issue lies is understanding that in terms of Windows 7 Security, every internal or external hard drive, plus folders, sub-folders and files thereon has an OWNER. Also each OWNER has a certain level of PERMISSION to do things such as moving files to a different folder, deleting or re-naming them etc. If you try to do things that you don't currently have Permission to do, that is when you get an ‘Access Denied’ error message. Also your system has an Admistrator or Administrators and at the outset you need to ensure through the Control Panel that you are listed as one of them. .
If, like me, you didn't realise these things, (and why would you if Microsoft or your computer or hard drive suppliers couldn't be bothered to really make sure you knew about them), then trying to fathom the ‘Access Denied’ problem becomes a stressful and frustrating nightmare as I can testify having spent a week at it!
The steps that I took to resolve the issue and which I believe now constitute the 'Correct Answer' are as follows:
First make sure that you have Administrator rights on your system via the Control Panel
Next ‘right click’ on the Drive whose files you want to gain full access to, for example the drive that your pictures are stored on, and click on 'Properties'.
Under the Security tab you will see a list of Groups and Users on this drive and the Permissions that they have to do things.
Before doing anything to edit these Permissions, first click on the Advanced button. This opens another window with a tab showing the Owner of this drive.
Click on the Owner tab and if you are not already listed as the owner, make yourself the owner by selecting your name from the list. I believe it should appear there if you are an admistrator or user. (In my case at this stage the owner was initially shown as an obscure string of numbers and letters which I believe identified the drive when it was connected to the lap top I was using before I upgraded my machine)
Now be sure to check the box that says "Replace Owner on Subcontainers and Objects" and the click Apply. On completion of this step, the drive in question and all the folders, subfolders and files thereon should now be 'owned' by you. You could check this out by right clicking on a particular folder then clicking Properties > Security > Advanced > Owner. Your name should appear. So far so simples!
Now go back to the Security Tab for your drive (Step 2 / 3 above) and look at the Permissions you currently have. Your aim now is to allow yourself 'Full Control.' If you don’t currently have this level of permission click Edit, select your name on the list, check ‘Full Control’ and 'Apply' the change.
I think I'm right in saying that at this point whilst still working in the Drive directory you are now given the option of ticking boxes which allow you to, in effect, cascade the permission you have just granted yourself to all the files and folders on that drive. Tick the box to allow this and Windows should then take care of the rest.If I'm not quite correct here then in my particular case, for example, all my images were stored on my external drive. The top level, or 'parent' folder in which all my pictures could be found was the 'My Pictures' folder and I had created a number of folders and subfolders ('child ' folders) within that folder. The permissions I gave to the Parent folder – My Pictures – were cascaded down through the Child folders.
On completion of the above step I tested the result in Windows Explorer by dragging a few files back and forth between folders and it now worked perfectly - I was now able to move / delete / rename etc all files without now getting the dreaded access denied message. What a sense of relief! This meant that I could now open Bridge normally rather than having to right click it and 'Run As Admistrator' - albeit that is a very useful thing to do until you get the problem sorted as described.

Is there a way I can use my external hard drive without the files being transferred on to my computer? as like like my iTunes music being on my hard drive without them being copied onto my computers hard drive ?

is there a way I can use my external hard drive without the files being transferred on to my computer? as like like my iTunes music being on my hard drive without them being copied onto my computers hard drive ? because i dont have that much memory and i wanted my external hard drive to be the source for my music files and not my computer.

Many users keep their iTunes libraries on external drives. You just have to remember to connect and power up the drive before launching iTunes.

I want 2 put music from cds on another ipod without the songs being in my library. Sorry it cut me off on the title. I want to import songs to put on my brother's ipod, but when I try to delete the song from my library it deletes it from his too. Help?

If you want to delete content from your computer but keep it on the iPod (so that is not deleted next time you connect it to iTunes), you need to set that iPod to manage the iPod content manually.

Generally when creating a Word file from either a Mac or Win7 pc and opening it on two different machines (either one first) it always prompts that the file is open and will be opened as read only. However opening a CSS file does not prompt that it is alr

Generally when creating a Word file from either a Mac or Win7 pc and opening it on two different machines (either one first) it always prompts that the file is open and will be opened as read only.
However opening a CSS file does not prompt that it is already open on or from any machine which is causing code edits to be lost.
What we found from out testing:
- The file can be saved from one user to the server and WILL NOT PROMPT on other machines until the saving machine has the Dreamweaver program closed completely
- The file can be closed and Dreamweaver minimised to the launch bar but it still will not register on other machines that it has been changed.
- Also, until the Dreamweaver program is closed on the machines, it will continue to open it's saved version of the file.
Example Scenario:
- User 1 opens test.css (which is 2000 lines) and adds some code to the end of the file to bring it up to 2500 lines
- Meanwhile User 2 opens test.css as well (opens as 2000 lines as User 1’s edits have not yet been saved) and adds in code to bring it to 2300 lines
- User 1 saves his file and closes it - but Dreamweaver is still open.
- User 2 also saves his file and leaves Dreamweaver open.
- The server will report the size and last edit of the file the same as User 2 as he was the last person to save it (and if you open from the Win7 Machine it will show as User 2’s 2300 line version)
- If User 1 then open's the file again (from either the 'recent' in Dreamweaver OR clicking on the file directly in Finder...which version opens.... The version that User 1 saved! Not the true version on the server, but the version that User 1 edited and saved with 2500 lines in it.
- Same for User 2, he will open 'his' version with 2300 lines in.
Other information:
- Files are opened directly from the server
- Sometimes the users will save incrementally and re-open
- Most of the time users will save incrementally and keep the files open
- The users will never not save incrementally and just save when closing the file once finished
- The users are usually working on the files all day
- It is always the bottom lines of code that are lost. It could be a case of the two versions being mixed up and cutting off the newly added lines based on the line count (possibly).
It is as if Dreamweaver is holding a cache of the version locally and then only properly looking back to the server when it has been completely closed. It is very difficult to see how the server is causing such an impact on these files, there are very few logs which are giving any indication to the root cause of the problems.
Anyone know if this is a known issue?
Is there a way that there can be a featured implemented on the server that doesn't allow another user to open a file if it is already open on another machine?
Thanks

Your server file handling has nothing, and really nothing to do with Adobe software. If files don't get locked for (over-)writing and/or lose connection to the program opening them, then your server is misconfigured. It's as plain and simple and that. Anything from "known file types"/ file associations not being set correctly, MIME types being botched, crooked user privileges and file permissions, missing Mac server extensions, delayed file writing on the server, generic network timeout issues and what have you. Either way, you have written a longwinded post with no real value since you haven't bothered to provide any proper technical info, most notably about the alleged server. Either way, the only way you can "fix" it is by straightening out your server and network configuration, not some magic switch in Adobe's software.

When I want to attach a file to an e-mail I'm sending from my iCloud account it makes the file show up in the body of the e-mail instead of attaching it as a separate file the receiver can open. How can I change this?

It should be an attachment. Your Mac just displays a preview of certain attachments (such as .pdfs) in the body of the message. A PC, for example, will see it as an attached file rather than a preview.
You can save the attachment on your Mac by Control-clicking on it and selecting Save Attachment.
