Picture control uses up all the resources

I am using picture control to plot data. As the number of data points increase,the CPU resource usage increases. It finally reaches 100%. All I am doing is drawing the points on the picture control.

hi jvg,
you are accumulating draw commands in your shift register.
Your accumulated commands adrawing the same points over top of where they where before. If you just pass the outputs of draw functions to the picture control, the new points will be drawn over top of the previous picture.
So,
in your example, toss the picture-shift-register and just wire to the picture control.

    Hi there dworthen,

  • Fetching all the resource request

    Hi,
    How to retrieve all the resource requests using a method?
    The below method returns the requests for a spefic resource object with the status as "Approved".
    tcResultSet rs= reqIntf.getRequestsForObject("iPlanet User", "approved");
    I want to retrieve all the resource requests.
    Thanks & Regards

    public Thor.API.tcResultSet findRequests(java.util.Map phAttributeList)
    throws Thor.API.Exceptions.tcAPIException,
    tcAPIException
    Returns a list of requests that match the provided attribute list.
    Just give your criteria from the list (you can see this API in the given link)
    I haven't tried but give:
    Map a = new Hashmap();
    a.put("Objects.Object Status.Status","*");
    Then you can sort this resultset depends on your use case.
    It should work..

    Let me know the results...
    AND
    getRequestsForObject will give you all the request for one object only.

  • Where can i find the magnetic lasso tool in adobe photoshop touch? i used it all the time before but suddenly cant find it please help

    i started my photoshop touch after some while and now i cant find the magnetic lasso tool it used to be there i used it all the time for editting but now i cant find it maybe i disabled it somehow. can anyone tell how to enable it again?

    I honestly don't remember a magnetic lasso tool. (I've been using PS Touch since version 1.0.) The closest things I can think of are the Quick Selection Tool, the Scribble Selection Tool and the Magic Wand Tool, all located under the same set of tools (3rd set from the top in the tool panel).

    I am using Windows 7 Home Premium 64-bit OS.I've never had this problem before... today I opened iTunes and it prompted me to download the newest version.  I use iTunes all the time and have updated it multiple times with no issues.  During the installation process it gave me an error message that said: 
    Runtime error! 
    Program C:\Program Files\iTunes.exe
    R0634
    An application has made an attempt to load the C runtime library incorrectly.
    Please contact the application's support team for more information.
    I quit the installation, uninstalled iTunes and rebooted my computer.  I now receive a similar message with a slight difference:
    Runtime error! 
    Program C:\Program Files (x86)...
    R0634
    An application has made an attempt to load the C runtime library incorrectly.
    Please contact the application's support team for more information.
    I did not leave anything out from the error message.  It doesn't point to a specific file, it just ends with "(x86)..."  Every time I boot up my computer, this error message pops up on my desktop.
    How do I repair this issue?  I have found multiple suggested solutions but am unsure which one is the best, and I don't want to try a bunch of different things for fear I may make the problem worse.  I would like to try and fix this myself if possible but I need to know if that is really possible or if I need to take my computer to someone for repairs.  Any suggestions will be greatly appreciated!!

    Hi lustyln,
    I'm having a little trouble understanding all of what you are trying to explain. From what I can tell, it sounds like your PC has a lot of software problems and you want to know what is supposed to be there and what isn't.
    For reference, here are your product specifications:
    http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c01893242&lc=en&product=4043282
    To get your PC software back to how it was when it was first purchased, run a system recovery:
    http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c01867418&lc=en&product=4043282
    I hope this helps.

  • IPhone 5 using data all the time

    My husband has had his iPhone 5 for a couple of weeks.  We have Verizon 300 mb plan, as he is mainly just using it for calls and text.  But it is using data all the time!  Today our online Verizon account is showing 59 episodes of data usage.  They are small, but still, why are they there?  All he has done is call and text.  He would like to keep the cellular data on because he texts by talking to it.  He did not send anything close to 59 texts.n was not on the Internet.
    We have turned off practically everything.  Location services, stocks, weather, email, notifications for everything except text and calls.  Stopped it from sending data to Apple.  He has added only 4 apps- cam wow, talking bird, talking cat, and free cell solitaire.  Not signed in for iCloud or Facebook or anything.

    Is Digi a CDMA carrier? or is it GSM/UTMS?
    If CDMA, that's normal. The technology was not designed for data and calling.
    If its GSM, give them a call to seek resolution.

    I've installed three times with no luck. I downloaded the Creative Cloud Packager off the licensing site: https://licensing.adobe.com. I unpacked and choose my applications. The install seemed to be successful, but I don't so any of the applications anywhere.

    Hi,
    Creating package doesn't mean it will install the product,
    You will need to install the package now. Please follow the instructions mentioned in the below articles
    Creative Cloud Help | Creating or editing packages
    Creative Cloud Help | Deploying packages
    Please let me know if it doesn't help.

  • Won't display my gadgets - explorer does - so not gadgets - what gives - use to all the time - not anymore - how do I get them back

    All of a sudden my gadgets don't display in my igoogle home page. Use to all the time and they will if I use internet explorer it just happens with mozilla firefox.
    How do I get them to display properly they just are listed on the left hand side of the screen.

    Symantec need to update their Firefox add-ons so that they are compatible with Firefox 4. They have indicated that for Norton 360 they plan to release an update to Norton 360 to support Firefox 4 in early May - http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20100720113635EN&ln=en_US
    Pending the update by Symantec, if you want to use the Norton add-ons you will need to downgrade to Firefox 3.6.
    To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data.
    You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.
    To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.
    For details of how to find your profile folder see https://support.mozilla.com/kb/Profiles

  • Can someone make iBooks have the Option to view 2 pages in landscape mode so it can use up all the pixel real estate?

    Can someone make iBooks have the Option to view 2 pages in landscape mode so it can use up all the pixel real estate?
    Apple usually does this for OSX and its great when compared to windows where it doesnt use up all the real estate for viewing applications like websites and pdf files but when it comes to iBooks, it feels like there is no apple touch to it and is limited.
    If steve jobs were still alive, i bet there wouldnt be this problem >.>
    Please consider this as a real problem for people out there who would like to see 2 pages in landscape mode with pdf files and not just epub files.
    Thanks!

    Penguin, do you always insult people on here or was I just a special case?
    If you read the statement carefully, which you obviously did not! I was speculating, and I did not say anything for certain about knowing or not knowing ...
    I'm happy for the reply to the post and helpful link you posted to where I can leave some feedback for my post on an Apple monitored site but i rather you not reply if your gonna leave a snyde remark with every helpful comment.
    Don't do it again. and Thanks for the help.

  • Safari using up all the RAM

    if I leave Safari open for an hour just regularly browsing sites, Safari and its other process Safari Web Content will use up all the available RAM on my computer. I have 4GB total, and eventually Safari will use up all the rest, usually 1-2GB. Any idea what's going on here? I have adblockers, such as Glimmerblocker, and extensions in Safari but they didn't affect Safari this much before 5.1/Lion.

    Using Lion on 17" MacBook Pro -
    I don't know about MDS - don't know what it is - but after seeing available HD space disappear gradually down to nothing when using computer - I tried all sorts of disk cleaning utilities - and have found that ---- AT THE LEAST --- gian swapfiles are engulfing the var/vm folder, taking up that HD space.
    I read elsewhere that this is a Safari memory management problem.
    Is it also MDS, whatever that is?
    Is there a solution?
    Sometimes restarting or doing shutdown and restart helps.
    Sometimes the same HD space remains disappeared.
    HELP!

  • How to find a cloumn or table used in all the reports

    Hi ,
    Suppose I have like 15 to 20 reports and i want search a particular column or table where it has been used in all the reports.Is there any easy way ?
    Thanks,

    Well "used in reports" can mean different things. Column used for display or columns used for filtering for example.
    For a filter column you could literally search for
    MyTable."Sales Rep"Whereas for a display column you'd need to search for
    MyTable.&quot ;Sales Rep&quot ; (without the blank space after quot
    That's simply due to how stuff gets stored in the webcat:
    <saw:column formula="MyTable.&quot;Sales Rep&quot;" columnID="c3">PS: How can you correctly escape the string &quot so it doesn't become " in here?

  • Just upgraded...why can't I see the information section on the left hand side anymore in iphoto '11? I used it all the time.

    I've just upgraded from iphoto '08 to iphoto '11 and I'm really missing the information pane on the bottom left hand side (under where events, album, libraries etc are).  I used to use this all the time when importing photos to sort them into Events and now I can't seem to get it back.  Does it not exist in the new iphoto?  Thanks, Hellen

    That info section is a drawer on the right hand side of the iPhoto window.  Click on the Info button at the lower right corner:
