Run programati​cally w/ stop option

I have created a vi that runs programatically, but I want it to be able to stop in the middle of running the program if the stop button is pushed.
I put the vi in a while loop and want the condition to be if stop is false. I tried to connect a local variable to the condition, among other things, but can not figure out what I need to connect to the condition if I cannot directly connect the stop button to it. Any suggestions?

I want to stop the vi that I start programatically with a button on the front panel of that vi. I have attached the program this time to clarify the question.

  • Programati​cally stop and start computer process

    Is there a way to programatically start and stop computer processes/services using LabVIEW?
    Thanks,

    Which OS? For Windows you can use System Exec to execute DOS commands to start programs. For services use the net start or net stop <servicename> commands.

  • Start Stop option

    Hi, I am creating a playlist for a party, so I am using the start / stop option to keep the track lengths to a party 3 to 4 minutes each.
    Is there a way, either through iTunes for some convenient App to tell me how long each song will play for, and hence how long the playlist is running for? (iTunes only displays the total track length).
    If I could find a way of exporting this info into EXCEL, that could be a start.
    Thanks....

    Since this is more of an iTunes related issue... and you're posting in the iPod forum, I would suggest that you re-post your question in the iTunes for Mac forum.
    You're more likely to get a better answer there.

  • Is it possible to trigger an error so that the running stored procedure is stopped?

    Hello all,
    I want to run an existing stored procedure and then I want to manually trigger an error/abort/interruption so see what happens and do some testing with that.
    Is it possible to manually trigger an error/abort/interruption on a running stored procedure so that it is stopped?
    If yes, how can I do that?
    I hope someone has an idea. For me it sounds not really difficult, but I just do not get the idea how to do it.
    Kind regards
    Peter

    Hello Visakh,
    I dont want to modify the existing procedure. I just want to run it and than stop it, but not with the button to stop it, but "kill" it somehow with an error (with not destroying the database).
    Nope you cant simulate an intermediate failure inside procedure code from outside. For that you have to modify the actual sp code itself
    Another way is by doing data manipulation in such a way which causes a error in procedure but for that you need to revisit the logic to ensure you do changes in such way as to cause an error

  • Re: Toolbar--Is it possible to get a "Stop" option so page won't redirect?

    I very much enjoy using the M/FF browser and I apologize if this is a question that reflects my ignorance of the current toolbar options with Firefox. In brief, does a "Stop" option--one that freezes a page at a certain moment while it is in the process of loading--exist on the current M/FF browser?
    Between 2006-2011, I did not have internet access. I recall, however, that earlier versions of the M/FF browser (Flock, for instance) offered a "Stop" icon on the Toolbar. One advantage of this option was that by instantly "freezing" the page, the user could prevent redirected to an undesired page. The option was useful because it offered the user greater control over the loading of webpages.
    Maybe such an option does not exist any longer. If so, could you let me know. If it does exist, I'd like to find out if I can install it on my M/FF toolbar. Again, apologies if my question reflects a deficient understanding of the current state of web browsers in general and yours in particular.
    Thanks.

    Firefox 4 and later use a combined Stop/Reload/Go button that is positioned at the right end of the location bar. During the page load process it shows as a Stop button and after the loading has finished the button is changed to a Reload button. If you type in the location bar then that button becomes a Go button.<br>
    Firefox als has a setting where it gives a warning when a page is redirected. Then you are no longer automatically redirected. You can set that in Options > Advanced > General.<br>

  • How do I get u-tube videos to run smoothly.  They stop and start and jump.

    How do I get u-tube videos to run smoothly.  They stop and start and jump.

    Sounds like they are buffering because your internet speed is way to slow.
    To check your internet speed, go to: > Speakeasy Speed Test
    or > Speedtest.net - The Global Broadband Speed Test
    Plus you can also check your internet speed using the Activity Monitor, which is in your Utilities Folder.

  • Is is okay to run R12 rapidwiz with upgrade option when 11i instance is up?

    Hello,
    Is it okay to run R12 rapidwiz with option "Upgrade oracle applications" while 11i DB/Apps are up and functional which is to lay down the R12 applications code tree as part of R12 pre-upgrade steps?
    Can you please clarify if running R12 Rapidwiz with upgrade option modifies anything at the database level and effects existing 11i system?

  • The way to stop process chain running takes forever (without stop)

    Someone here used to say in order to stop a process chain running in the middle, we can go to menu: Process Chain -> Remove from Schedule.  However we have never made it successful since it runs forever without a stop.
    Maybe there is a background process that we can go to kill them immediately that make the whole process chain run really stop?
    Thanks

  • 9i GSD is running on node ''. Stop the GSD and rerun root.sh !!

    Hi there,
    I am getting following error while running root.sh in first node ( Clusterware installation) ..There is no HACMP running , there is no 9i installed either.
    Checking to see if Oracle CRS stack is already configured
    Checking to see if any 9i GSD is up
    /crshome/crs/product/10.2.0/crs/bin/lsdb: Cannot allocate memory of size 0
    9i GSD is running on node ''. Stop the GSD and rerun root.sh
    Note : I have checked in root.sh (CRS_VNDR_CLUSTER) this variable is playing something..
    Can you please suggest what to do ?
    Thanks for all your input.
    Cheers

    If you have Oracle 9i RAC on the same cluster and would like to have a Oracle 10gRAC database also.. there is a paper that you can find on Oracle RAC SIG website that tells you have to co exist both Oracle 10g and Oracle 9i RAC databases.

  • Read jpg files and stop programati​cally

    Hello,
    I would like to have my program stop reading the jpg files in a folder programatically. These pictures are formatted similar to a movie, to correspond to a graph. The graphical output will stop programatically but the jpg files continue to be read and outputted. In this situation, the graph will stop but the "movie" will continue. I would like them to both stop at the same time and the last jpg file read at the time when the stop button is pressed to be display. If the program is stopped halfway through the data, the graph will display half the data and the "movie" will also stop halfway through the jpg files. This is similar to pressing the pause button on your VCR or DVD player. I've tried several things an
    d none have been successful. Thank you.

    Instead of putting a For loop around your code to display your "movie" you should put a While loop around it. Wire up its condition terminal just like the one for the graph, except use a local vaiable of the stop button. This should make your movie stop about when the graph does. Unfortunatly this won't act quite like a pause button, you won't be able to resart where you left off. It could be done though, you'd just need a bit more coding in both loops.
    Good luck

  • Programati​cally update the Report Option dialog in NI Test Stand 4.2.1

    Hello,
    I would like to know, what is the procedure to modify Customise the Report Option dialog window with custom default value before displaying the window to user.
    We are writing our own process model to customise report options, Database option and User Management module of Test Stand. I am unable to update the Dialog window with modified settings.
    Please help me.
    I followed the instructions mentioned in link http://forums.ni.com/t5/NI-TestStand/Programmatica​lly-change-station-option-in-TestStand-2-0-1/td-p/​...
    But this is customization for the single sequence and also this is not updating the Report Options Dialog window. Please find the screenshot which i want to customize.

    Hi
    The screenshoot you have posted is done my CVI- modelsupport2.dll with funcion DisplayReportOptionsDialogEx.
    in side is code there is ReadReportOptionDefaultsEx (this function will be also used in model sequence "Get Report Options")
    it will read "TestStandModelReportOptions.ini" .
    So there were 2 solutions.
    1. ) Changing ReadReportOptionDefaultsEx (Not recommend because changing stuff from NI is bad, by chaninging you are in charge off)
    2.) Just change the ini File for your needs.
    Hope this helps
