Will be the leak memory for the queue when it is used in producer and mode of consumption data acquisition transfer different size table.

In data acquisition, I use a loop to query the data from the hardware, another loop to receive the data from query sent by queue loop.

Each time the size of the transferred data matrix is perhaps not the same, so the system can assign different table size and recycle frequently.

It cost memory leak. Or it will slow down the performance, given that the size of the array is not fixed, so everytime need to create a new array of size.

Any suggestion or the best method.

If I understand your description, your DAQ loop acquires data with the parameter of the function of reading-'1 ' for reading at the DAQmx samples. This translates into different picture sizes.

Passage of these tables directly to a queue is valid and she didn't mind important in performance (at least AFAIK) and it certainly does not leak memory.

So the question is more or less:

It is valid that the consumer receives sizes different picture for analysis? How your consumer manages these tables?

hope this helps,

Norbert

  • My printer HP F-340 in one stuck in the queue when I try to print images.

    My printer HP F-340 all-in-one stuck in the queue when I try to print pictures but works fine when I print the letters and documents... Yes the printer fails only when I try to print photos or digital images (even the small photos).

    Could someone provide me with support to find out how to fix this fault? I already managed the "HP autofix tool" and said that everything is OK.

    Any help would be appreciated so much. Thank you.

    JMF60.

    HI - sorry for the late reply.  It does not resemble the printer hardware, so I wouldn't worry about the printer being the end of his life.  At this point, I think that I recommend to uninstall then reinstall the printer software.  This problem seems to be really driven by the computer/software.  This document will guide you through the uninstall of the printer.

    This document will guide you through the installation.  If you no longer have the CD that came with the printer, you can download the latest driver of the printer from here.

    BTW - nothing has changed between the time it worked, and when you started having the problem?  (Installed new SW, other hardware changes, etc.).

    Hope that helps.

  • What is happening in the original file of the photo when I import it in Photos and I have the "Delete after import" box checked?

    What is happening in the original file of the photo when I import it in Photos and I have the "Delete after import" box checked?

    When organizing photos for Photos for Mac app, I find that the Photos makes "copies" of files within the library of Photos and must reference a file if your settings are such that you do not copy the original files in the Photos app.

    Trying to manage the disk space for the Macbook Pro.

    The delete after import is available only when you import a device - a camera, card, an iPhone, but not when you import files from a folder on the system drive.

    You can delete the local image files of your system drive yourself, once you have imported the Photos and they were copied in the photo library.

    I would never use the option "delete after Import. The files will be deleted until you can check if the files have been imported correctly. If you find out later, that some of the imported files are corupted and illegible, it will be repeated o toolate import, because the files have been deleted from the device. Or worse, if pictures should plant a reason any during the import, all the pictures will be lost, if you have enabled "delete after import.

  • When I try to install Firefox, I get an error "could not open the output file. I used Firefox before and it doesn't work anymore, so I uninstalled. Cannot re - install now.

    When I try to install Firefox, I get an error "could not open the output file. I used Firefox before and it doesn't work anymore, so I uninstalled. Cannot re - install now.

    This has happened

    Each time Firefox opened

    I tried to download firefox.

    Mozilla/4.0 (compatible; INTERNET EXPLORER 6.0; Windows NT 5.1; SV1; AntivirXP08; GTB6.3; .NET CLR 2.0.50727; MS - RTC LM 8)

    When you click on the download link on GetFirefox.com, you should be asked if you want to run or save the file. If this situation occurs when you try to run the download, try instead to record and put the file on your desktop or in a similar place, where you are certain that you can find.

    When the download is complete, try double-clicking on the downloaded file in the normal Windows Explorer (browse your way to the file from the desktop). This should start the installation.

    If, in the Explorer window, you notice that the file seems to be missing the Firefox icon orange/blue, right click the file and select Properties. The image should look like the attached picture (except that mine is in Danish, but that is irrelevant) if saved correctly - if it don't look like this, would you please describe the content or attach a screenshot of the box. Especially what it says under "File Type" - it must be 'program '. If this isn't the case, will have to focus on what could be the problem here.

    A bit off-topic, your Internet Explorer seems to be quite a bit outdated (IE 6, where the current version is IE 8), so I highly recommend that you try to run Windows Update to get your system up to date. Is it as a society (such as a thin client Terminal Server computer) system, this is not possible, and most likely, your system administrator will have to help you.

    After getting the leak memory, look at DropletEventServlet in the Navigator component of/dyn/admin, and you can see the accumulation of mappings element of the page in question form. DropletEventServlet is a component to extended global (regardless of the scope of managers form she monitors) and does not remove the entries over time (which is why it is important to not use IDS in the form element cards FormHandler, and he issues a warning once you 500 for a form).

    My guess is that the bug you see is a fixed bug CCS been resolved in more recent versions of the ATG (2007.1 and later versions). You can see a newer version of the ATG to see if the form is always encoded in the same way.

  • OfficeJet 4500 510n - print jobs stuck in the queue when using wireless

    Hello

    I bought just a new Officejet 4500 510n yesterday and I have a Dell with Windows 7 64 bit laptop that I connect to the USB or wireless. The reason for this is that sometimes, the laptop is not right next to the printer and we need to print things (for example, my wife works upstairs sometimes with the laptop and the printer is downstairs in the living room). I was able to get the configuration of the printer on both the wireless and USB without any major problems and it prints fine when I print via USB. However, when I print wireless, the print job appears in the queue and shows that it is printing, but he never curls work all the way. The work gets "stuck" while waiting in line, for example, it gets stuck at 772 bytes of 940 bytes

    I downloaded the HP Print Diagnostic here tool and ran it and and it passed all the tests first time. However, when I goto the last test, which is to print the test page, it sends the print job to the queue and then everything gets stuck as indicated above. I was able to cancel the job and it comes off very well, but restarting the work does not work, it just get stuck again. Meanwhile, I don't get ANY error messages at all.

    Here's what I've done regarding troubleshooting:

    -Ping the printer - spent

    -Restart the service print spooler - no change to the problem

    -Check that the printer is set as deafult - spent

    -Update of HP Ran to ensure there is no missing updates - found 2 updates and install them

    None of the above has solved the problem, so I'mm this ad here in the hope that someone may have had this problem before and fixed it.

    Thank you!

    Thanks for the reply.

    It turns out that I could solve it myself. I went to add the printer wireless on another laptop, I have here on my home network and it printed a page of test very well, so I thought it must have been a bad installation on the main laptop.  I removed everything and reinstalled as a wireless printer, and it worked perfectly. Amazing what can make a bad installation.

  • Printing which is held in the queue when you preview before printing is by default

    I have a HP2575 while a printer on my home network.

    I just installed this printer on my new laptop (running on Windows 7) and can print ok until I set mode as a default print preview in the print preferences.  When I do that print jobs themselves that is held in the queue on my laptop.  I tried reinstalling the printer but nothing helped.  Print jobs cannot be cancelled (so I have to go where the tasks spoulées are deposited to remove them from the queue).

    It's weird because my old laptop (also under Windows 7) worked well.

    Everyone comes through this before?  And, if so, do you have a solution for this annoying problem?

    [I like well have print preview by default to check exactly what I print, for example to ensure that there is no page useless waste of paper]

    I'm not really sure what is the cause.  Try the procedure described in this document to clarify what is happening.  Let me know what happens.

  • Removing photos rejected when the catalog is in offline mode will remove the file when the disk is reconnected?

    Hello

    Let's say that I am not connected to my lightroom files and just navigate using the catalog offline.

    Now imagine I reject and delete a photo, lightroom deletes the actual photo in the folder of the next time my photos liebrary is online? (or will it just remove Intelligent forecasting and thumbnail library and keeps the file source intact without my knowledge of its existence?)


    Thank you

    K


    Thank you for your patience and to specify your query.

    As you say, you have created Smart Preview and unplugged the external hard drive.

    Now, if you apply the filter to the rejected images and try to delete the images, you will get the dialog box below.

    As you can see, it is said that it will remove the file only from the Lightroom Catalog.

    As it is impossible to find the source location, you will not be provided with an option to remove the images from the computer or external hard drive (in your case).

    The files will remain as it is on your external hard drive.

    If you want to remove the both original files, I you suggest to connect the hard drive and then choose Remove disk to remove the catalog, as well as an external hard drive.

    I hope this helps.
