  I bought Photoshop CS2 in 2005. I recently changed my PC and load the software on the new PC.  I load the CD and proceed through the steps.  When it's time to serial number software tells me the serial number on the CD case is invalid.  It is the same serial number, I used previously.  How do I remedy this situation so that I can use the software on my new pc?

  First, use the serial number to the right of the download for Windows.

  

  Do not place information in the field of the Organization after you enter the number. Which causes problems.

  If you have windows 8, you may need to change the directory to progra ~ 2 on some 64-bit windows systems:

  The reason for the use of progra ~ 2 on a 64-bit system when installing a 32-bit application is the 8 character limit imposed by Windows. PROGRA ~ 2 totals up to 8 characters, program ~ 2 is 9

  You have 2 options:

  1. in the installation, change your path to C:\progra~2\... and install it. It should work.

  2 copy Setup on your local drive. The right click on Setup.exe, properties > Compatibility tab > run in compatibility mode. The choice of XP SP2. Click OK. Run Setup.exe

  Either we have to work.

• How to measure the execution time of a specific to a VI process?

  Hello! My VI has two processes: compression and edge detection image and I'm trying to measure the execution time for the process of detection of edge of my VI, but I don't know how to do. Please give me some ideas on how to do it. Thank you!

  There are several ways that you can do.

  -L' one is using the number of cycles before and after your vi to get time like here: http://digital.ni.com/public.nsf/allkb/6F6B9F4E149C80578625652800784764

  - or use the profiling: https://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/profiling_vis/

  Edit: If you're open to suggestions:

  -You have not to load the image inside the loop instead, make him outside of the loop.

  - And I see of many IMAQ buffers are not removed properly. You can have everything at once by Images (No) by logging in to Boolean TRUE: http://zone.ni.com/reference/en-XX/help/370281P-01/imaqvision/imaq_dispose/

• too low execution time

  I tried to measure the execution time. The rate is 1KS/s through to read 100 per channel in a loop of 10 and samples. The time should be about 1000 ms, but it is only 500-600 ms. And when I changed the rate/number of samples, the run time does not change... How could it happen?

  Well,.

  The task inside the loop compensation is something of a problem.  (The error handler must jump on the second iteration)

• SQL execution time

  Hello

  I was wondering if anyone could advise on the best way to capture the following in an 11g database.

  Say that we have;

  -a piece of SQL execution by up to 50 times per minute.

  -unique execution times vary.

  Aside from dba_hist_sqlstat and generate a sort of average over a period of 30 min.

  What would be the best way to get the execution time of this piece of SQL in real-time.

  say I want the individual execution time of this last of 100 executions.

  Any help would be appreciated

  Thank you

• Oracle NoSQL YCSB - continuous increase in execution time

  Greetings,

  I'm testing with YCSB nosql databases. I'm new to this type of databases, but I already tried few of them. I use the VM with 2 GB of RAM and hosted on Win 7. Although it is not recommended, because I work in the environment of capacity now, I use KVlite. But my problem is confusing and I can not find the reason. So, I have successfully loaded data and tested NoSQL Oracle using different workloads. However, each time, I get the higher execution time. For example, if 1 performance I get 20 seconds, if I stopped database and next day run even workload once again, I get 35 second run time and so on.

  Do you have an idea of what may be the cause of that? As I said, I did research on some nosql databases, but I've never had that strange results.

  Kind regards.

  I can't say with certainty why you see the results you have described, probably is just that with every race on the same data store, more data is getting integrated into the KVlite.

  It is not a good idea to use KVlite for a test YCSB.

  KVlite links to your application instance and does not provide the kind of partitioning of a key space that is normally essential to YCSB workload.

  The idea of YCSB is to provide a random workload on a large number of keys and then to make things as expand data store while the operations are happening and see the impact.

  These kinds of operations on random data access workloads cannot be expected to scale on a single data store instance that distributes keys.

  I suggest that you use an appropriate version of kvstore to run these tests.

  Hope this helps,

• Query execution time

  Hello

  Maybe a stupid question, but I would like to know if it is possible to calculate the execution time of a query.

  I know ' set timing on ', but I can't use it, because I don't have any environment for the needs of the school project.

  I have to select all the orders for a line in a table with more than 1,000,000 records (easy ^^) and there are 100 users simultaneously connected.

  How long is the execution time and the impact of 100 users (Oracle 11 g)?

  Of course, it also depends on the server, the table index, etc., but this should be ignored.

  Maybe somebody has a tip or a white paper?

  Thank you

  It depends on the code that you are proposing.

  If you are using bind variables and/or analyze only once, your application is scalable and the number of users is not serious.

  As part of the memory is to be locked during analysis, analysis each time or do not use do not bind variable, your application allows serialize access to the database, and the amount of resources will be directly dependent on the number of users. In doing so, your app is impassable.

  The number of users will now be certainly serious.

• I recently bought an iphone 6s and I'm having a hard time activating my number imessage FaceTime.

  I recently bought an iphone 6s and I'm having a hard time activating my number imessage FaceTime. I migrated to an iphone 6 and where everything worked like a charm to a nightmare without end I tried all support apple suggests more change my sim card, twice, even try different phone numbers did not work. I spoke with my carrier to check any international obstacle on my serve - no luck there. Contacted by phone - apple support chance either. I EVEN DEMANDED TO REPLACE MY UNIT WITH a DIFFERENT ILS DID and guess what - STILL NOTHING! I'm running out of ideas and patience. I even tried my number deauthorised for imessage/facetime and the Lady at apple support had no idea they could that, even if Apple has a webpage set up for that matter! Last but not least, I charged a sum of rediculus of money for "Invincible" sms for activation of apple through my device for activation - ALL for NOTHING! Can someone in the Apple support give me a solution to this?

  What country are you in and who is your provider? iMessage and FaceTime activation use SMS to the Apple activation servers to the United Kingdom. If you use a carrier not supported, it may not work. If you use a supported media, make sure you have your account set up properly for an iPhone.

  Hello

  How to shorten the execution time of the NXT brick?

  The software is 2012 LabVIEW for LEGO MINDSTORMS

  Thank you.

  

  

  Hi 40123157,

  You use the module in an appropriate manner, and there is no simple way to improve the time of loop iteration beyond what you've done. Here are my suggestions:

  (1) the i2c commands take a long time. In your application, it may speed up if you run only move the engine only when the engine speed has changed.

  (2) for this particular example, you do not use the release of the report engine. If this VI does not need to run it can be removed.

  (3) If you need to speed up execution other than that, as a user advanced LabVIEW, you can create a copy of the VI of engines to move and change it as you choose. All you have to to the "DC motors' entry is use cluster to array on the cluster, as shown below. I think you can speed it up by running all the settings before the loop (type sensor and fixed connection configuration), and removing the value of power if you send only the values between-100 and 100.

  (4) drawing on the screen can be slow you down here.

  

• How to calculate the execution time of a SCTL in FPGA VI?

  Hello

  Can someone guide me that how to calculate the execution time of a SCTL for an iteration in the FPGA VI?

  Thank you and best regards,

  Rashid

  Hello r,.

  A SCTL will always run in a beat the clock it has been linked to.  So, if you use a 40 MHz clock, this loop will run in 25 ns.  If the code cannot complete in that, or if it requires two graduations of the watch to do the calculation, your code does not compile, then you have the guarantee that this will always be how long it takes this piece of code to run.

• Why the execution time increases with a while loop, but not with "run continuously?

  Hi all

  I have a problem of severe weather that I don't know how to fix it because I don't know exactly where it comes from.

  I order two RF switches via a data acquisition card (NI USB-6008). One job at the same time can be selected on each switch. Basically, the VI created for this feature (by a colleague) resets all the outputs of acquisition data and active then those desired. It has three entrances, two chain simp0le controls and a cluster table, that contains the list of all the outputs and some practical information to know what is connected (specific to my application).

  I use this VI in a complex application, and I have some problems with the execution time, which increased whenever I said the VI, so I did a test VI (TimeTesting.vi) to determine where the problem came. In this special VI I record the execution time in a csv file to analyze then with excel.

  After several tries, I found that if I run this criterion VI with the while loop, execution on every cycle time increases, but if I remove the while loop and use the funtionnality "Continuous run", the execution time remains the same. In my high level application, I have while loops and events, and so the runtime increases too.

  I someone could explain to me why execution time increases and how can we avoid this? I have attached my VI test and the necessary subVIs, as well as an image of a graph that shows the execution time with a while loop and «run permanently»

  Thanks a lot for your help!

  Your SetReset_DO VI creates a channel whenever it is called.  And that you never delete a task.

  When running continuously, that it's as if it only runs once and LabVIEW has internal mechanisms to close references that will not be used again.  When a VI is used as a Subvi, LV does not know if she will be called again, and lacks these things until the first level VI stops. You have a memory leak.

  Just as you open and close your file outside the loop for, create your channel out of the loop.

• Execution time of the XML CVI functions increase when loop

  I wrote several functions with CVI who read XML files. I confirmed in the utility of monitoring resources I have cleaned all my lists, items, documents, etc. I found that when I loop one of the functions I created, the execution time increases. The increase is small, but it is sensitive and does not affect the performance of my.

  Are there other sources of memory I need to release? It seems that there is a leak memory somewhere, but I can't see where this increase.

  I am running LabWIndows/CVI 2009 on Windows 2008 Server. I closed my functions using TestStand 4.2.1. Any help would be appreciated!

  Thanks in advance,

  Kyle

  Hi Daniel,.

  After some playing around, it turns out that the source of my problem was due to running my program as a Debug version, rather than a Release. As soon as I build in a configuration of output, the function remains coherent and quick time loop.

  Thank you for the research on this problem for me.
