Is there any way to limit the number of times that a PDF can be opened?

I run a small publishing company and we want to provide exam copies of our books to professors. At present our exam copies have the words EXAM COPY as a water mark on every page and we've also made the files so that they can't be printed or easily copied. However, we'd like to also restrict these PDFs so that they can only be opened 5 times. I've read about FileOpen but that approach seems a bit more complex than needed. Is there any other way to restrict the number of times that a PDF file can be opened once it is downloaded? Thanks in advance for any suggestions.

DRM soltions like FileOpen are your best bet for PDFs. Others include Adobe's LiveCycle Rights Managment, LockLizard, Armjisoft PDF Security OwnerGuard, etc.
They all work and are priced differently, but there's really nothing for what you want to do that is both simpler and secure.

Is there any way to limit the number of Threads running in Application(JVM)

Hello all,
is there any way to limit the number of Threads running in Application(JVM)?
how to ensure that only 100 Threads are running in an Application?
Thanks
Mohamed Javeed

You should definitely use a thread pool for this. You can specify maximum number of threads that can be run. Be note that the thread pool will only limit the number of threads that are submitted to it. So donot call "Thread"s start() method to start thread on your own. Submit it to the pool. To know more, study about executor service and thread pool creation. Actually it will not be more than 20 line code for a class and you might need maximum of 2 such classes, one for threadPool and other one for rejection handler (if you want).
Just choose the queue used carefully, you just have to pass it as a parameter to the pool.
You should use "Bounded" queue for limiting threads, but also be careful in using queues like SynchronizedQueue as the queue will execute immediately the threads submitted to it if maximum number of threads have not been running. Otherwise it will reject it and you should use rejection handler. So if your pool has a synchronized queue of size 100, if you submit 101th thread, it will be rejected and is not executed.
If you want some kind of waiting mechanism, use something like LinkedBlockingQueue. What this will do is even if you want 100 threads, you can specify the queue's size to be 1000, so that you can submit 1000 threads, only 100 will run at a time and the remaining will wait in the queue. They will be executed when each thread already executing will complete. Rejection occurs only when the queue oveflows.

Is there a way to Limit the number of guest accounts a Sponsor can create from the sponsor portal?

Hello,
I am trying to find a way to limit the number of guest accounts a Sponsor can create from the portal. I am running ISE 1.2 and I am finding it difficult to limit the number of guests a sponsor can create.

Interesting feature that unfortunately is currently not possible. I also don't think this is a feature that will be offered in the highly anticipated v1.3. I would recommend that you reach to your Cisco team and request this feature.
Thank you for rating helpful posts!

Is there any way to limit the number of RFC calls from xMII to SAP R/3

Hi All!
I wanted to know whether the number of simultaneous RFC connections made from xMII to SAP R/3 system can be controlled in any way. Suppose we have a scenario wherein some million Sales Orders or Production Orders are to be updated in SAP R/3 from xMII in a short span of time. For all these updations to take place, multiple RFC calls will be established from xMII to SAP at the same time. This will increase the load on the SAP R/3 system and affect performance of the SAP R/3 system. Is there any check on xMII side to limit the number of RFC calls that can be made to SAP R/3 system?
Regards
Anupam

Anupam,
If you are using 11.5 just keep in mind that the JCO connection points to a single application server (based upon the SAP Server alias connection settings), but the traffic itself to make a BAPI request is effectively the same as any client user traffic. There will obviously be limitations on performance and throughput, with network and server constraints added to the number and size of the R/3 requests, but there is no magic formula to plug-in because of all of these variables.
If you are using 12.0 (or plan to migrate when it goes GA) then taking advantage of the JRA (java resource adapter) and the associated application server pooling that it offers on the NetWeaver side of things will greatly help you in the throughput capacity.
If you have put some of your xMII application into either test or productive use and are running into issues then I would highly recommend entering the specifics into the customer / partner support portal so that they can help you through any associated problems.

Jeremy Good

*Is there any way to limit the Chart Bar size dynamically?*

Hi
I have selected the Marker size as Medium for my Bar chart.
Bar chart bar showing too big when there is only one bar.
Is there any way to limit the bar size dynamically?
Thank you

hi Ruwan,
Don is correct in that there is no option in the chart design component to do this.
what you can do though (i know it is a pain) is to
1) create a new chart in a new section with a narrower bar using the chart options dialogue
2) create a conditional suppression formula for the new section and the old chart section based on the value returned in the Show Value for the chart
i have created a request for a charting overhaul [here |https://ideas.sap.com/community/products_and_solutions/crystalreports;jsessionid=B3E2E9F6A6CC9C9F5321659382A91855.node0]in the ideas place which includes a solution for this particular issue. please feel free to give it the thumbs up if you think that this is a worthwhile idea.

If you had find my iphone activated on the iphone itself before it was stolen, then you may be able to track it.
Otherwise, there is nothing you can do.
Sorry.
Report it to the police and your wireless carrier and change your password.

Is there any way to get the server app other that through the app store. We do not have our system conneted to a network. I typical downloaded items on a non-apple system.

is there any way to get the server app other than through the app store. The system that I need it on are not connected to the internet.
We run a closed-loop network of apple systems and I tipically downloaded updates on a non-apple system that was on the internet.
Any ideas?

I did buy the server app, went to the app store to download it. This system I'm using for downloads is Snow Leopard 10.6.8, it shows that I can download it but only as an Install which says I need 10.8. I can't seem to find a way for it to just download as a package or .dmg file so that I can copy it to DVD/CD or flash drive.

Is there a way to count the number of times an array moves from positive to negative?

I have an array of values, and I need to find the number of times that the array changes signs (from positive to negative, or vice versa). In other words from a graphical standpoint, how many times a certain line crosses the x-axis. Counting the number of times the array equals zero does not help however, because the array does not always equal exactly zero when it crosses the axis (ie, the points could move from .1 to -.1).
Thanks for you help. Feel free to email me at [email protected] I only have lv 5.1.1 so if you attach any files, they cannot be version 6.0.

Attached is a VI showing the # of Pos and Neg numbers in an array, with 0 considered as non-Pos. It is easily modifiable to other parameters - including using the X-axis value as your compare point versus only Zero.
This is a modified VI from LV (Separate Array.vi)
Compare this with your other responses to find the best fit.

Is there any way to increase the number of codecs supported in FCE?

Hi all - does anyone know if there is a way to allow FCE to natively edit more codecs than are listed in the default sequence settings? I use FCPro and have been encouraging folks at my University to use FCE for intermediate editing. I just found out that many formats supported in FCP are not supported in FCE.
Are there any plug-ins or anything we can buy to increase the types of files that FCE will support (in a sequence without rendering)?
Follow up: if not, can anyone tell me the specifics of the 720p30 AIC format that FCE uses?
Apple Intermediate Codec
1280x720
30fps progressive?
bitrate?
audio sampling rate?
It seems odd to me that FCE has such a limited number of formats it supports natively. And why isn't ProRes 422 a part of FCE? I thought that was their big thing now - HD wihtout taking up all the real estate that AIC does.
Thanks. I'm frustrated with both iMovie and FCE and wishing that Sony Vegas worked on Macs!

Hi(Bonjour)!
Well FCE is a stripped down version of FCP, for a fraction of the price. It was aimed to produce TV content in TV native resolution.
In the past years, HDV and AVCDHD were added through AIC codec.
For most of FCE users (from the beginner to intermediate video editors)those formats are adequate.
To have access to native HDV or to Apple ProRes 422, you have to buy Final Cut Studio 2. All those codecs will be available in FCE export with quickitme conversion settings.

In Numbers, is there a way to limit the number of characters in a cell?

Hi,
New to communities, so I apologize for the length of this question.
I have exported a spreadsheet from one source and am opening it using Numbers. In one column - lets say column C - the list contains 35 characters.
I am trying to import this spreadsheet into another program which will only allow 30 characters to be in column C.
I have been unable to find a way to limit column C to 30 characters so I am able to import it into the new program. The field will contain numbers and letters.
Any help will be greatly appreciated!

ricochetron,
you can place Jerry's suggested formula in any column convenient for you. If column D is unused then do the following:
enter the fomula in cell D1. Shorthand for this is:
D1=left(C1, 30)
then hit the enter key.
now select D1 and copy using the menu item "Edit > Copy". Now select the whole column by clicking the letter "D" in the column reference tab:
now paste using the menu item "Edit > Paste" to fill the formula to every selected cell in the column:
You can now copy the limited text from column D and paste as needed. If you paste to another cell or table you should use the menu item "Edit > Paste Values"

Is there any way to control the zoom factor so that when my SSIS Package is opened, it is entirely visible within Visual Studio?

I have formatted my SSIS Package beautifully, if I do say so myself, so that all my tasks are visible at 50% zoom. However, when I close my project and then re-open it in Visual Studio, it defaults back to 100%...YUK!
I did find this post which didn't seem to work...even to the point that no where within my xml could I even find the "PersistedZoom" Parameter. I even tried manually adding it, I couldn't find the exact syntax on it, and that didn't even work.
1. In BIDS (Visual Studio) first close all open SSIS packages / xml files to avoid confusion ...
2. Right click on the SSIS package and select the "View Code" menu item. (to open the actual xml)
3. Search for all instances of "PersistedZoom" and change the value directly to the right of it to 100 (mine
was 80 or 90 ...)
4. Now save and close the XML file.
5. Now open the SSIS package in the designer, you will notice that it is still scrolled to the bottom right!
6. Now make any small change (I scrolled to the top-left and just slightly moved a task)
7. Now save and close the designer
8. Re-open the SSIS package in the designer! and what do you know it does not start scrolled down to the bottom right anymore!
Let me know if you still have issues - but as I said I followed this same process on all my problem packages and they ALL now open correctly.
I noticed that after doing all this the PersistedZoom property disappeared from the xml, which leads me to believe that if I zoom in and out of my packages again it will probably get stuck by opening to the bottom right again ...
Can anyone help me out with this?
Thanks for your review and am hopeful for a reply.
PSULionRP

There is no way to preserve view preferences.Just remember or annotate the zoom % used in the package.
You may want to open an MS Connect item asking to add such a feature.
I can tell you it may not be implemented because a package may be opened on different size monitors.

Is there any way to recover the broken iMovie files, that were moved to a different unauthorized drive?

I moved the iMovie projects and events folder to a regular harddrive. I know now, i the aftermath that it was a wrong thing to do, and i was wondering whether there are some way to recover the projects to use them in iMovie again?

More details on why you think a regular harddrive was the wrong place to move a movie.
What other kind of harddrive is there besides regular? Irregular?

I lost my contacts, texts etc after syncing my phone to itunes for first time since 2012, now all I have is info. starting from 2012. Is there any way to recover the contacts, texts etc that I have lost for the last 2 years? So ticked off at apple!

I am hoping that someone can help me understand how it can be so easy to lose the last 2 years data on an iphone by synching to itunes for the first time since 2012? If this happens from itunes automatically overwriting your phones system why would'nt there be warnings and red sirens going off on your phone? Can somone please let me know if this lost data is recoverable and maybe even let me know how to recover it?
Thank you

Glad to help! The reply you got was very generic and didn't completely address your questions.
Basically, all it said was to restore your backup. What I addressed was your query about how and why this happened. iTunes did give you prompts and warnings. And if you'd used iTunes back in 2012, then you'd have lost much less data when you made the incorrect selection.
Do you have an iCloud backup? Were you backing up your device at all?
I just found it amusing that you were 'ticked off at Apple' when Apple didn't cause this problem. You did.
Have a great day!
