Group VI freezes after throwing a panel near

I am under Labview 15 and try a very basic VI to impliment into my full program. I will be essentially four stations for the acquisition of data running and you don't want closure if one of them is running the program. So I have 4 Booleans wired to terminals OR whereas they should throw if one of them is on, or false if they are all off. The problem is when I have one or more on and you try to close the VI it does not close (hooray! this part works) but when I want to continue testing and turning all back off to see if I'm allowed to close if they "do not perform" I can't change anything and my VI is frozen until I have stop.

I'm learning just bare with me program if the solution is very simple.

Thank you

Yes... The solution is very simple...

The problem is the flow of data.

The Panel closes event records as soon as the VI starts. Unfortunately, the structure of the event is outside the loop so it is never checked. Consiquently, when the event occurs LabVIEW locks the user interface until it can be repaired. However, it cannot service because the structure of the event does not work until the loop stops and you can not stop the loop because LabVIEW is waiting for the event to be repaired...

To resolve this problem, move the buttons inside the structure of the event and put the structure of the event inside the loop.

  • My computer constantly freezes after startup

    Original title: System Hang

  • Vista Home Premium 32 bit freezes after an indeterminate amount of inactivity

    For the last few weeks, my HP Pavilion dv6500 laptop has been freezing after periods of inactivity. Seems that the only change made to the computer until that moment was a Windows update that was late about 3 - 4 weeks. No other programs have been installed.

    I have not precisely timed duration yet, but I think 10-15 minutes of inactivity in freezing results. Little happens is important if the lid is open or closed. Only "a freeze" is to do a hard restart.

    I ran in Mode safe... same results. I did a system restore to a point before the update of Windows. I reinstalled the latest graphics and audio drivers. I ran SpyBot: Search and Destroy... we found an approximately 18 items requiring repair or removal, but it also has not fixed the problem. I ran Check Disk and the problem still persists.

    I'm running out of ideas, and this problem is driving me absolutely crazy. I hope someone can help before I lose my mind. Thanks in advance.

  • Why the back my mail list, text and phone iphone 6 freeze after upgrade ios10

    Why my list of e-mail, text and phone iphone 6 freezes after upgrade ios10?  Have you tried to turn it back on.  Becomes a real pain in the uknowwhat.

    I had the same problem at first but I was testing the first version of ios 10.  but the reason may be due to the low storage? If your storage space is ok please go to settings then general try to look for the software update again just to make sure that you use the latest version of ios usually there a few times an update immediately. If none of these solve the problem, try now button the power button and the home button at the same time (the screen of your iphone turns off a few seconds) touches both simultaneously when you see the apple logo on your screen if all else fails you can try connecting your device to itunes on a pc and run a quick diagnostic test? you go to itunes on a pc if you have already installed on your pc, laptop etc... Look at the upper left side... Click the help... Go to the bottom of the list to "Start the diagnosis" (make sure that all the test boxes have a tick and click ok to run the test) PLEASE NOTE your iphone you will need to be connected to the computer before hand... hope this will help you know if there is a problem, but when I came across this problem with my camera it was because my storage was almost full on my device and in icloud if This is the case then you need to maybe buy more storage or delete applications or games, you do not use this should help solve the problem of storage (if your device is low on storage)? hope this helps somehow.

  • Firefox 16.0.1, videos youtube freeze after 2 seconds. FF injuries.

    Videos YouTube freeze after that 2 seconds... audio game continues for 5 seconds on it. The whole browser stops responding and I have to ctrl + alt + delete at the process level to close FF16.

    After that I uninstalled my customized version, so BONE STOCK FF16 is miss you, this is a new installation. I tried the current version flash 11.4 and 11.2 flash version to get my problem is solved.

    NO ID CRASH. No formal don't crash in itself, just a browser totally unresponsive.

    By the way... Chrome works youtube without incident. WTF.

    In addition, this problem does not exist on my installation of Waterfox... a variant of 64 free bits of 15 FF. Maybe I have a sort of x 64 issue. I think that maybe that's the problem with the standard 32-bit version of FF16. Ask me again why this happened in the first place.

    I run McAfee OAS Business Class A / V, never had a virus or something in 4 years.

    SOLVED. Watefox is the only way it seems. Needs of Firefox to fix this flash on its own it seems.

  • Satellite X 200 freezes after 15 minutes of inactivity

    I'm tired of this problem: my laptop freezes after 15 minutes of inactivity and I can get it going again to reset. The problem was solved when I reinstall Vista, but after several months my laptop started hanging up. And my laptop is unable to install Tempro 2.0.3.

    Please, help me to solve this problem and I don't want to reinstall Vista again.

    Hello

    For me it sounds like that a 3rd party software application or is causing this problem because you wrote that after Vista reinstall, the problem has been resolved.

    I put t know this software you have installed, but you need to remove all unnecessary applications as shareware or trial versions.
    Then use CCleaner to clean the registry.
    Visit the Windows update website and install all the updates that are available for your Windows.

    In the worst case, you will need to reinstall Vista again. In my opinion a reinstall from time to time is normal and I have reinstall my laptop every year. So I often have good performance.

    Hello

    The forum already contains these discussions where notebooks will freeze after 5 or 10 minutes of play. Have you read them?

    Now it s not easy to say what causes this problem but first of all you need to install the latest driver of Toshiba display. Don t use non-Toshiba drivers, as they can cause the overheating!

    Also make sure that you use the latest version of the BIOS and it s useful to clean the laptop time using a jet of compressed air.

  • Toshiba 32L4333DG freeze after DTV tuning

    Hello everyone,

    My first time here. I really need help with my Toshiba 32L4333DG TV.
    It completelly freeze after any DTV channels tuning/upgrades to date.

    Made to another owner the same TV?
    Y at - it any suggestion of support from Toshiba?

    Thanks in advance.

    Does the first day of purchase?
    How about affecting the default return TV? Give it a try.

    But you must understand that there is no possibility of troubleshooting.
    All you can do is to reset the TV and update the firmware (if possible)

    Where this problem occurs again, you should get in touch with Toshiba service in your country to check the device.

  • Portege R600-10 q keeps freezing after a short period of use

    Hi I have a Portege R600-10, q,

    It keeps freezing after a short period of use - although if I leave it for a few minutes, sometimes it can be useful.
    If it is turned on for long enough, it will display a blank screen and the fans will turn on very hard.

    I cleaned ports ventilation and re-glued the CPU, and it did not make a difference.

    I ran HDD and memory (mhdd/memtest) diagnostics, and they have all done.

    I reinstalled Windows (from the OEM disc) and I still see the same question.

    Anyone have any ideas on how to solve this problem?
    Thank you

    Hello

    Have you noticed that when running special software or apps?

    I can tell you that a memtest does not always provide a good result
    Even if the memtest said there is no problem with memory, RAM modules could malfunction

    Otherwise, it may be a motherboard problem, but this is just speculation

  • Satellite U400-22n and Win7 - screen freezes after 5 min

    Hi, this is my first post

    I ve bought a new U400 with preinstalled Vista last week. 2 days ago I ve upgraded to windows 7 32 bit professional when I looked at install windows prompted me that it requires a full install, so I did install a normal full, windows 7 installed normally.

    Now my screen freezes after 5 min and windows go black s and restarts after 3-5 min, I ve downloaded all the drivers from the Toshiba site I ve used the auto detect and installed the drivers one by one and tested if restarting stop s, I reinstalled windows now 4 - 5 times returned my copy to the store and got a new copy of windows DVD , it s the same.

    A Please someone any advice for me. Like the store I ve this perch will not upgrade to windows 7 for me.

    Hi mate

    The U400-22n seems to belong to the series of PSU44E.
    There is a special BIOS for Win 7 32 bit 4.80 - WIN32.

    Please update it all first!

    In addition, the unit supports the Chipset Mobile Intel GL40 Express and graphics card.
    The latest graphics card driver can be downloaded from the Intel page

  • SAT S1800-921 freezes after 5 minutes

    This laptop freezes after 5 minutes. The only solution is to unplug the power supply. It is usually impossible for something like 20 minutes to restart the computer.
    Already tried operating system sector / boot in the bios-update / reinstall.

    Sometimes when I start the laptop nothing happens at all but the Green led indicating that the laptop is on.

    Anyone suggestions... Please?

    Hi people,

    I don't know any virus that will prevent a computer until it has passed some time. The only thing I know to cause this behavior is overheating causing an internal thermal trigger to operate. It must then cool enough to reset before you can find. Of course the longest (and so more fresh) the laptop's left over it will eventually work before freezing.

    Check that the cooling system is not obstructed in some way (dust or proximity loose papers, fabrics for furniture etc.).

    Kind regards

    Hello

    I think you should test the memory modules.
    The memtest software is OK, but not perfect. You know
    Even though the memtest would not detect any errors, the problem of the ram is possible
    Otherwise, it could be a motherboard problem too.

    I had a problem in the past, my book of 8 years froze only if adapter was attached to only if the html files were executed.
    Finally the mobo was replaced, and this fixed the problem.

    What internal temperature? Maybe it's at a higher temperature?
    Clean the vents with air... stream could help get better air circulation...

  • HP G62 laptop computer: laptop freezes after startup

    After starting my laptop freezes.  How long after starting varies.  Sometimes it will freeze after only a few minutes. Sometimes it can be operational for an hour or two.  Want to know how to fix this.

    Tested hard drive and the Long DST failed.  Has given an ID of the failure of QAGCHR-5GH847-XDOO3A-61AKO3.  Product ID is XHO66UA #ABA.

    Hello

    Error code 24 characters is a failure of the entire test (DST) disk Self and would indicate that hard is defective and must be replaced.  This is also consistent with the freezing issues you describe.

    If you want a guide on replacing the hard drive yourself, let me know.
