How to speed up the rendering of JavaScript annotations?

Hello

I use JavaScript to create annotations about 30 on a PDF page. I then use the property of true/false .hidden to hide/show the annotations.  I'm hide or view annotations, it must be 4 seconds so that changes occur, either for the hidden annotations become visible visible annotations to hide.  The JavaScript code that changes the visibility is triggered by a mouse on a button click event.

I couldn't cope with the slow if 30 annotations becomes visible or invisible in order that the user watched.  However, there is absolutely no change for 4 seconds then all 30 annotations change simultaneously visible or invisible, according to the current state.  Because nothing is happening for 4 seconds, users often think that the click of a button is not respected and click the button again.

Is it possible to speed up the rendering of the annotations?  Or y at - there a way to force changes in annotations to be displayed individually each .hidden property is changed?  Once again, at the present time, nothing changes on the monitor until all 30 annotations have been changed and then all the changes appear at the same time.  The time of rendering, measured at 4 seconds, you mad my users!

Thanks for any idea that someone has!

Dave

There could be several reasons for this:

1. your code is not effective. If post you it here, we could have a look on

and see if it can be improved.

2. hardware your computers is not up-to-date.

3 acrobat/Reader is simply slow.

Another thing to consider is using some kind of progress bar to let your

users know that the action takes place, so that they are eager

During these 4 seconds. There is an object embedded in Acrobat/Reader that can

do exactly that. Look at the thermometer object.

    In windows 7 Professional 64-bit. How to speed up the removal of the files. It takes 1.5 to 3.5 minutes to remove a file

    Before I give you a sensible answer in the following paragraphs, why don't you try not to create a new admin user account & try that.  I have absolutely no logic behind this suggestion, it's just that I've seen some strange symptoms in the other forum posts that have later been attributed to user profile problems and the test would take less than the time of deleting a single file without talking about relocation.

    Resettlement is a pain in the neck, so anything that resolves things without this point is worth.  Mine took me several days more sorting over several problems of McAfee.

    If the Dell disk is labeled 'réinstallation DVD' then he will do what is necessary because this is a full version of a Windows DVD installation [this is also what I have for them and that I used recently to reinstall from scratch].  Anyway, boot it from the disc only is not a destructive or dangerous act then you might try & see if the menus & options for the "repair installation" appear or not.  Just escape before you tell it to do anything then use again when you've prepared everything [backups, etc.].

    Your safe mode test confirms that Windows is at fault and not a third-party on your PC application.  The result of the safe mode is in fact a good result because this means that when you set Windows & malicious programs, you should be fine.

    Using the SpiritX AV cleaning tips will help you see if the malware is what corrupted Windows or if Windows comes to decide absolutely bloody & wreck itself.  If it is malware, so you still need to clean things up before the relocation to ensure that malicious software fails to cling to something during this relocation [I am simply repeating SpiritX here as I know nothing].

    It occurs to me that this Exchange did not once mention the Dell Factory Image Restore Partition.  This procedure is a little easier than relocation complete & it preserves the Dell-bundled utilties.  This is in essence an automatic & custom reinstall.  Before you begin this or even nothing else, in which case Dell did he not bring to your attention, you might not realize that Dell DataSafe Local Backup has a facility to make a USB / backup DVDR the Dell Factory restore partition .  This means you would retain the possibility to make a Dell factory restore in the future what you did with the hard drive in the meantime.  A disadvantage is that it would permanently replace the partitions that you have set up yourself [for Windows XP Mode or any other purpose] it really means return to the State wherever it was when you first opened the box.  My factory restore USB is 6.4 GB [Home Premium x 64 edition], but yours could be bigger - they advised me to use a 16 GB USB DRIVE as it was the size of the partition itself, then you can check the size to decide what USB can be required.

    I noticed that you talked to start in F8 for the repair menu or using a boot of the system repair disc. I guess you tried or had Dell try this for you.

    Good luck & patience.

  • How do I update the rendering of HTML articles

    Hello

    I have a long article any HTML my folio (smooth scrolling enabled for both orientations). When opening, article is cut off at any time, and part of the text and images is missing. I have to turn the Tablet for re - make the display of the article and if I do a few times, the article shows completelly.

    The HTML article also contains buttons with a javascript to reduce/enlarge the font size. By hitting the buttons, the Viewer is there, but the visible part is not updated and the content is hidden again.

    How can I set the Viewer to refresh the page (with extra button?) or how do I set the Viewer so that it always displays the full article without turning the Tablet all the time?

    Thank you

    Yves

    Unfortunately, there is not a way to trigger, through JavaScript, a query for the web control is used update the height of the actual page of the HTML content. If you have very long pages, you can see the bug you mention, because it takes too long for the operating system to display the page and when we ask the web control to the height of the content, it has not yet finished and we get a wrong number.

  • How to speed up the process of updating after clean install

    original title: updates after a clean install

    I just performed a facility clean my machine that runs Vista Home Basic Edition and is now trying to download all the updates it has had over the past three years (ex-factory).

    However it will slowly (no surprise) and I was wondering is there something I could do to speed up the process.  Currently, I am just by clicking on start - Windows Update and let it download what they want from there.  However I have noticed saying she "Download 80 updates", it installs then say 5 of those, restarts and then says "Download 75 updates"-have I really downloaded updates and then lost 80 them, or he really download only 5?

    I also thought the oldest download first, but I can't seem to find an opption to do this - is - it possible?  It seems just stupid for me to download updates of 2010 before those of 2008 (assuming that's what he does lol!)

    All advice or pointers that would help to do that, go a little faster would be immensely appreciated.

    See you soon

    Start by installing the latest Service Pack (see http://support.microsoft.com/kb/935791). You'll have so far fewere updtes to install.

    Also note the following regarding your answer to the question of PA Bear "clean install has been through choice. After 3 years machine has become bloated and slow, and I decided to wipe them fresh, start over and give up unused programs that seemed a good idea at the time. » :

    In my view, it is usually a mistake. With a minimum of care, it should never be necessary to reinstall Windows (Vista or any version). I ran Windows 3.0, 3.1, WFWG 3.11, Windows 95, Windows 98, Windows 2000, Windows XP, Windows Vista and Windows 7 now, each for the period of time before the next release is out and everyone on two or more machines here. I never reinstalled none of them (with one exception--a problem that I worked on for weeks without success), and I've never had anything more than an occasional minor problem.

    It is my belief that this erroneous notion comes from the technical support people in most of the major OEMs. Their solution to almost any problem, for they know not quickly answer is "reformat and reinstall. It is the ideal solution for them. It gets you phone turned off quickly, it almost always works, and it does not need to do any real troubleshooting (a skill that most of them has obviously not in any great degree).

    But it leaves you with all the work and all the problems. You must restore all backups of your data, you must reinstall all of your programs, you must reinstall all Windows and updates of the application, you must locate and install all the necessary drivers for your system, you will need to recustomize Windows and all your applications to work the way you are comfortable with.

    In addition to all these things being long and painful, you may encounter difficulties with some of them: you will find all your CDs application? You will find all the necessary installation codes? You have data backups to restore? You still remember all the customizations and settings that can be installed to make everything work the way you like it? Sometimes there are problems that are so difficult to resolve that Windows has to be reinstalled properly. But they are few and far between; RESETTLEMENT should not be a substitute for troubleshooting; It should be a last resort, to do that once all other troubleshooting by qualified person attempts have failed.

    And perhaps most important: If you reformat and reinstall without knowing what caused your problem, you will most likely repeat the behavior that caused it and quickly find yourself in exactly the same situation.

    Firefox tries to cache as much as possible. When you do rapid iterations, this can lead wrongly showing you an old version of Firefox cache.

    To see what sees a 'new' visitor, reload the page using one of the following methods to work around the cache:

  • How to speed up the performance of Tecra A4

    How can I speed up my Tecra A4 performance. I don't want the usual diskfrag and the cleaning disc. Is there an I can change to improve the performance of specific parameters?

    Hello

    I put t know how you are familiar with computers, but the best way to optimase performance is to disable unnecessary applications at startup in MSCONFIG. Tecra A4 is beautiful unit. I put t know how much RAM is there, but if you want better performance I recommend you update maximum (2 GB). Upgrading, you can use compatible RAM module:

    512 MB DDR2-400/533 (PA3412U - 1 M 51) and
    1 GB OF DDR2 400/533 (PA3411U-1M1G).

    By the way: If you start the computer under Services management you will find a large number of settings and options. Check them and Google all over the place. Maybe you will find some tips how to disable someyou don t need.

    One last thing: in Device Manager, you can disable all devices, you need t (modem, PCMCIA, or something similar). All these materials cannot be detected at startup.

  • How can I change the rendering of the element wintitle?

    Hello

    I'm still fairly new to DITA and unhappy with the way the wintitle element is rendered in FrameMaker 12. Unlike uicontrol, which comes out in "BOLD", wintitle is completely undifferentiated ordinary text.

    Y at - it a simple way to change it to "BOLD" and maybe a different font, so that the names of the applications can be viewed differently?

    I have no idea how to change a DSP or even find ESD that controls this (if this is indeed how the character styles are controlled in DITA fm).

    Thanks for any help,

    Elisa Roselli

    Cambridge imaging system

    Hi Elisa,.

    ESD is located here:

    {path_to_FM}\Structure\xml\DITA_1.2\app\technicalContent\edd

    the model should be thisone:

    {path_to_FM}\Structure\xml\DITA_1.2\app\technicalContent\template

    DITA 1.2 is something, which is pretty well broken in every way and it is difficult to find things sometimes.

    If you stick with DITA (and not just to evaluate it), I would say to look more closely at DITA-FMx made by Scott Prentice (which is also here).

    This helps a lot.

    Also, I recommend to get training on the subject, like DITA is a beast to tame.

    Hello

    with speed suggest it would be always be expirement with indexing on parameters, after that first scans all what is currently happening in what concerns analyses of full table etc. which are "more expensive."

    Level of the specific actions on your code, that what follows comes out too expensive; -

    AND    WH_LEVEL_CODE NOT IN (SELECT WH_LEVEL_CODE FROM SHEET_HEAD WHERE WH_REVISION_NO = 1)
    

    Here, I would see if you can rewrite, perhaps with a left join / auto join to achieve the same ends, compare the timings, you might be surprised.

  • How to speed up the drive mapped persistent unavailable timeout?

    I have a mapped drive on my laptop that is only accessible when I am connected to my work VPN.

    If I'm not on the VPN or connected to the internet, open "My computer" or by searching for the results equivalent directory in a timeout, two Windows waits to try to access the drive.

    It is extremely annoying, because it takes time interminably long to determine that the drive is not accessible. How can I reduce this time? Is there a registry key, that I can change or some other parameter?

  • Question on choosing a second card GPU to speed up the rendering

    Hi all.

    I'm on first Pro CC 7.2.1 (for Windows) and I would like to add a second GPU card in the system, since CC PP supports several cards GPU for rendering.

    My question is this: the 2nd GPU must be identical to the 1st? or may be significantly faster (or less) and still the two cards will work well together without problems (i.e. adding a card GTX-780 to a system with a GTX-660 card already installed in it).

    Thank you very much in advance guys.

    Each complex will have something that is the "bottleneck".  For example, if you have two kind of evenly matched highend cards, then the CPU will be your bottleneck.  If you have two different cards then the old card may not even useful to have in the system.  It really depends on your support and the workflow.  If as I do have media HD AVCHD, most of the time I got out DVDS and have a hex core CPU overclocked use usually some effects MPE accelerated, then a second card could repay.  I ran a 680 GTX and GTX 660 cards with my new GTX 780.  If you are registered on our site PPBM7 you can see my results, currently the fourth result belongs with a GTX 680 and a GTX 780 and one below which is with just a 780 GTX

  • How to speed up the reboot

    Hi all

    After the upgrade to vSphere 4 (RS 4) we have course increased the virtual restart speed machine (after a SRM failover)

    in the previous version, we have seen a restart speed that seems to put in this way:

    1 virtual machine by host at the same time (5 in my env)

    now in the last recovery that we have seen 10 VM restart at the same time

    somewhere you seems different in 2VM by computer (host in the cluster)

    is anyone of you know if this setting is configurable? and where it change

    our guests are 24core and 64 GB of ram, we hope to have 3 VM starting with host and this will reduce over time to failover

    Thank you

    Hello

    High-priority virtual machines always begin with a

    With regard to the non-priority power on / low / normal VMs: SRM poweres on 2 virtual machines per host up to 20 virtual machines simultaneously (an another VMware said pdf 18).
