Bug? Control updates itself after VI stops running.

I just put together an example of using a notifier and a user event to communicate between two loops to help someone here. Pressing a button causes a notification to be sent to a loop which sends a user event back and then waits for 10 seconds. It then sends another event to signal it is complete. Simple. To stop the VI I use the Panel Close? event. That event sends a notification to the bottom loop to stop and stops the event loop.
Ok here is where it gets weird. If the 10 second task is running and you click the red X to stop the VI it imediately stops the event loop. Obviously the second loop is blocked until the 10 second wait is done. If during this wait time you click the red X then change the value of a numeric control, once the VI stops the control will keep incrementing.
Here is a screencast and a snippet.

Here it is in 8.2. I tested this with LabVIEW 2010 with the same results. It does not happen if I disable lock front panel in the event case for the numeric control.

    I also have this problem of Firefox updating by itself (also the add-ons) even when I turn off auto-update.
    Sometimes you do not want to update or download a large file; because you're working offline, have a slow connection, or have a very low download allowance etc. Usually the update doesn't work and cause Firefox to crash. After that it cannot be started again. This is with Firefox Portable but I think I've had this problem the normal Firefox. With the portable version I can just back up a single folder but it is still time wasting and annoying.
    I've noticed that when I start Firefox with auto-update turned off from the previous session, it changes the options to auto-update by itself, it also does this periodically. So every time I start Firefox I have to turn off auto-update, and I have to check again from to time, like a few times a day, because Firefox will by itself turn back on the auto-update.

  • Will iCloud update itself after it failed update as I updated to iOS 6?

    Hi, because of my poor 3G connection at the office, iCloud did not update its when updating my iPhone 4S to iOS 6 and therefore, Shared Photo Streams is not working.
    Is there any way to make sure this will happen some time in the future or will I just have to wait for my 4S to catch up at some point?

    Try:
    iOS: Device not recognized in iTunes for Windows
    I would start with:
    Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7
    or
    Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP

  • After recent windows 7 updating Adobe reader has stopped to run. Do you have solution?

    After recent windows 7 updating Adobe reader has stopped to run. Do you know solution?

    Three things to try...
    Using Windows Explorer navigate to C:\Program Files (x86)\Adobe\Reader 11.0\Reader, then double-click on Eula.exe and accept the license agreement
    Can you open Adobe Reader by itself?  If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)].
    It could even be a malware issue; see http://helpx.adobe.com/acrobat/kb/reader-core-dll-error.html

    yes wen i try booting in Safe Mode it behave the same. i have downloaded the combo update of 10.7.5 from another laptop, so how do i run it on my mac. THANKS for helping
    The goal is to mount the combo update .dmg on the desktop and then open and run it. If you can't get to the desktop to begin with, that won't work. Another approach is to treat the Mac's hard disk as just another HD by using a second Mac and then connecting the problematic one via Target Disk Mode. See http://support.apple.com/kb/ht1661. Note that both Macs will need Firewire ports and you'll need a FIrewire cable to connect them. With the combo updater, one of the steps in the process is to select the drive you want to install the update on. Once you're successfully connected in Target Disk Mode, the problematic drive should appear in the list.
    If that doesn't work or Target Disk Mode isn't possible, the only other solution is to boot into Recovery Mode; see http://support.apple.com/kb/ht4718. Note that once booted into recovery mode, you have access to Disk Utility, and you should try running Repair Disk after selecting the bad drive to see if something's wrong with the directory which could be fixed. When you select that drive, you should also look at S.M.A.R.T. Status at the bottom of the window. It should say "Verified." If it says Failing or Failed, the HD needs to be replaced.
    If the HD is OK, all that's left that I can think of is to reinstall Lion using Recovery Mode. I hope you've maintained current backups or at least complete Time Machine backups. Of course, if you have a backup and the backup is bootable, you could boot from that, wipe the internal HD clean, and clone the backup onto the internal HD.

  • How do I get an actor to wait for its nested actors to stop running before stopping itself?

    I'm developing a series of projects that are based on the Actor Framework and my actor dependency hierarchy is starting to get some depth. One of the issues I'm facing now is making sure that each actor will only stop running (and signal this via a Last Ack to a higher-level actor or via a notification to non-AF code that launches it) once all of its nested actors have stopped running.
    For instance, say I have a type of actor that handles communication with a microcontroller over USB - a USB Controller Actor. I might want to have an application-specific actor that launches USB Controller Actor to issue commands to the microcontroller. When shutting down, I want this top-level actor to send a Stop Msg to USB Controller Actor and then wait to receive a Last Ack back before sending a notification within a provided notifier to the non-AF application code, which can then finish shutting down completely.
    I'm sure that having actors wait for all nested actors to shutdown before shutting down themselves is an extremely common requirement and I'm confident National Instruments have made it possible to handle that in a simple, elegant manner. I'm just struggling to figure out what that is.
    The approaches I've experimented with are:
    Creating a pseudo "Stop" message for an actor that won't actually stop it running straight away, but instruct it to stop all nested actors, wait for their Last Acks and then shut itself down by sending Stop Msg to itself. This isn't elegant because it means the client will be forced to fire off these pseudo stop messages instead of Stop Msg to certain actors.
    Instantiating an internally-used notifier and overriding Stop Core.vi and Handle Last Ack Core.vi. The idea is that within Stop Core.vi, I send Stop Msg to each of the nested actors and then make it wait indefinitely on the internal notifier. Within Handle Last Ack Core.vi, I make it send a notification using this notifier which allows Stop Core.vi to continue and perform deinitialisation for the top-level actor itself. Figures 1 & 2 below show this approach. I wasn't confident that this would work since it assumed that it was possible for Stop Core.vi to execute and then Handle Last Ack Core.vi to concurrently execute some time after. These assumptions didn't hold and it didn't work. It would have been messy even if it had.
    Overriding Stop Core.vi, making it send Stop Msg to each nested actor and then waiting for an arbitrarily long period of time (100ms, 200ms, etc.). What if a nested actor takes only 10ms to shut down? What if takes 400ms?
    The figures below show how I implemented the second approach. Ignore the broken object wires - they only appear that way in the snippets.
    Figure 1 - Stop Core.vi from the second approach
    Figure 2 - Handle Last Ack Core.vi from the second approach

    I think that this would be a nice addition. I think how a program stops is just as important as how it starts.
    I think everyone who has worked on AF design agrees with this. Indeed, managing "Stop" was *the* thing that lead to the creation of the Actor Framework in the first place. The other issues (deadlock/hang avoidance and resource management) were secondary to just trying to get a clean shutdown.
    CaseyLamers1 wrote:
    I find the current code a bit lacking.
    My concern would be that the mixing of a verified stop and a regular stop could create confusion and lead to people having trouble during editting and testing with the project ending up locked (due to VIs left running which did not shutting down).
    Your concern is to some degree why no verified Stop exists in the AF already. We looked at each actor as an independent entity, and left it open to the programmer to add an additional managment layer for those applications that needed it. But over time, I have seen that particular management layer come up more often, which is why I am exploring the option."
    So that gives one of the reasons why this hasn't already been implemented but also points out that it's something quite a lot of people want.

  • HT1369 Ipod touch not being recognized by itunes (but is registering as an external drive by the computer itself) have updated and reinstalled itunes, stopped/started apple mobile device and removed and mobile programs associated with my non apple cellpho

    Ipod touch not being recognized by itunes (but is registering as an external drive by the computer itself) have updated and reinstalled itunes, stopped/started apple mobile device and removed any mobile programs associated with my non apple cellphone. This seems to have started happening after the last Itunes update I did as I was able to put music on my ipod touch a month or so ago. Is there some way to go back to an older version of itunes? I really have no idea what else to do since I followed every step on the trouble shooting page for windows 8.

    I had this problem too and my roommate solved it!
    Go to 'Settings'
    'Music'
    Scroll to the bottom and enter your password to log onto your home sharing
    Then connect to iTunes and sync!

I updated everything fully. Deleted spybot unintalled and reintalled the newest and one older version of itunes. still nothing. I tried to delete some files that is hidden as directed by apple. I have been trading emails with customer support but it has been no help at all. I am running Windows XP. Before i wiped my computer I ran itunes with no problem, on this computer, this week.

  • Oracle Linux 6.4 installs, runs, and manual shutdown OK ...  but restarts itself after 10 minutes or so

    Hi Guys
    Successfully installed Oracle Linux 6.4 operating system , which subsequently runs as expected.
    When Oracle Linux 6.4 is shutdown using  standard GUI  system/shutdown ,
    it does a clean shutdown and power-off as expected  ....
    UNTIL some 10 minutes or so later , when Oracle Linux 6.4 reboots all by itself from a fully powered-down state.
    Likewise when Oracle Linux 6.4 is shutdown using  standard command line " shutdown -h now" ,
    it does a clean shutdown and power-off as expected  ....
    UNTIL some 10 minutes or so later , when Oracle Linux 6.4 reboots all by itself from a fully powered-down state.
    Clearly it is NOT desirable to have the operating system able  restart of it's own accord.
    A manual shutdown is typically  done for good reason , and the server should remain shutdown.
    The previous version, ie Oracle Linux 6.3 did not exhibit this behavior.
    When Oracle Linux 6.3 was shutdown, it stayed shutdown
    Question
    ======
    Does anyone know how to STOP Oracle Linux 6.4 from restarting itself after a successful shutdown ?
    Thanks

  • My E-mail won't stop updating itself?

    Hi, as I said above the E-mail hasn't been able to stop updating itself and it's depleting my battery quicker than usual. I've tried turning off the push option and turned the iPhone off and on several times. It still does the updating on its own. Is this just a bug or is there a problem? Would also appriciate some tips or advise. Thanks in advance.

  • Update an existing bug doesn't show the new test run "steps to reproduce" in TFS

    Hello all...
    So let's say I have a bug. Then I run a new test because I've been told it's fixed. This second test fails. I choose "Update an Existing Bug" and I'm presented with the window that looks like I'm reporting a new bug - all the info is there. I save
    and close, go into TFS, refresh...and I all I see is the original bug that I reported, but none of the new stuff I just did. Where is that new stuff? I would expect it to push the old stuff down, and the new stuff I'd see above. My developers get mad at me
    because I've moved their tasks back to "To Do" but they see the old bug and complain that it's fixed, even though I have new info to report, they don't see it. I'm in VS/MTM 2012 V4...
    Thank you for your help!

    Hi OneOfThreeDevs,
    As you said that you did not see the new bug report in TFS after you
    reporting a new bug - all the info by choosing "Update an Existing Bug" option in test runner.
    I suggest you need to check if you can see the new bug report by selecting
    Testing Center->Test->Verify
    Bugs.
    (1)If you could not see the
    new bug report in the bugs list, I doubt that you may be not update an Existing Bug successfully.
    Therefore, I suggest you can refer the following link to create a new bug report by the update an Existing Bug.
    Reference:
    http://msdn.microsoft.com/en-us/library/vstudio/dd465175(v=vs.110).aspx
    (2)If you could see the new bug report in the bugs list, I suggest you can try to input the bug ID in Team Explorer Windows and then
    check this issue again.
    In addition, you can try to see the new bug report by the web access.

  • Windows update stopped running - no error code

    For some reason - presumably a virus, windows update stopped running. When I click windows update in control panel, screen freezes. Only way out is Ctrl+Alt+Del, access Task Manager - it reads Windows Update: Running, and kill the app. Help appreciated! 

    I have a problem, I got a message from the Lenovo solution center that "i never updated my windows" although I updated them and now I have windows 10. In order to fix this, they ask me to launch windows update but the thing is that I cannot launch it. I click on " launch" and nothing happens. I tried manually to find windows update and check for updates but there are no available updates any ideas?

  • Service suspended itself after iOS7 update!

    Service on my iPhone 5 suspended itself after I updated to iOS7. I had to manually re activate service a few minutes ago by logging on to Verizon Wireless's website. After reactivating service, a new window containing two pieces of news opened: one, I was congratulated for reactivating service, and two, I also was advised that the existing contract would be extended for an amount of time identical to the unsolicited suspension of service.
    How is this my problem? Why am I being penalized for a situation completely beyond my control? Verizon Wireless really grows into you, doesn't it?

    This is the response from a Verizon Customer Service Representative, when I requested their assistance restoring service. Please pay particular attention to text in bold:
    "I do see that when the device attempted it's reinitiation with the network the evening of 10/8 (which I assume is the evening you completed the update) it recognized a previous insurance claim from June where Asurion had reported the phone as lost/stolen. It appears you may have found the device and contacted them to reverse the claim, but the system still recognized the information being reported as stolen from Asurion".
    "When a software update through Apple is completed, it triggers the phone to reactivate it's wireless connections. This triggered the line to suspend when a new activation was attempted as a system security measure".
    "This is how the system is designed to keep your information safe and avoid someone being able to activate your lost/stolen phone onto their account. I'm sorry that it ended up causing so much frustration for you. I assure you that your account is safe and it wasn't due to anyone accessing your account unauthorized".
    "I do hope this helps to clarify what occured with your iPhone during the upgrade. I've confirmed that your Device ID and SIM have both been removed from our lost/stolen database for good, so you can complete future updates with ease and avoid this situation again in the future."
    As I said, service suspended itself after the iOS7 update.
