If this is an example of how your code looks, I'd clean it up before the developer who has to work on it next hits you over the head with his LabVIEW Style Book.

    I think by creating dll you can stop the while loop from your C program.For that you just create dll (Dynamic Link Library) for the VI which has that while loop.

    how to stop a while loop after certain time using Elapsed time vi.

    Hi Frankie,
    Just place the Elapsed Time VI inside the WHILE loop, and wire the 'Time Has Elapsed' output to the conditional terminal in the lower right corner (which should be set to 'stop if true' by default).
    In the future, please post your LabVIEW questions to the LabVIEW Forum.  You have a much better chance of getting your questions answered sooner, and those answers can then help others who are searching the LabVIEW forums.  Thanks!

  • How to stop While Loop in Event Structure with same button?

    I have a problem. I want to use one control to activate an event in a event structure, and the same control to terminate a while loop in that event.
    It is possible to use 2 controls to do this, but I need it to be only one.
    Thank you

    I have a bit different problem.
    I have a tab control, with several buttons on different pages.
    In the current situation, we can talk about two pages, where one page ("Settings") in the Image, has a START and EXIT button, while second page ("Wait") has an EXIT button.
    In a while loop, I have event structure, which handles events of the START and EXIT buttons of the Settings page. This is fine. But I also want to control the Exit button of the Wait page.
    The control works like this:
    When I click on Start in the Settings page, the front panel shows Wait page and attempts to connect to a datasocket server on the remote computer. If the user wants to stop this process, he can click on Exit on Wait page too. But, this doesn't give any immediate effect. On the even of Start button, the front panel is not locked, so the user can actually click the Exit button on the next page when it's visible. But it's of no immediate effect. Means, what the LabVIEW does is, finishes the execution of event in Start button's click, and while this executes, it doesn't consider the Exit button's refreshed value (shown in Red circle in the block diagram).
    Simple question: Is there any way to check the updated (latest/live) value of a control during some event's execution? Or if I write an Event "Value Changed" for the Exit button and pass it to some variable. Is it the only solution?
    Thanks ahead.

  • How to stop a while loop when using tab control

    How do you use a tab contol to stop what is happening on one tab when you switch to another tab?  In the test example I attached, I have a while loop nested inside a case structure controlled by the tab control.  When I tab to page two the elapsed timer starts but when I switch to another tab it does not stop.  I can't come up with an easy way to stop or exit the while loop when I change tabs. 
    Thank you

    I played with it a little more and came up with this fix.  This fixes it but is not tied to the changing tabs as I was looking for.  Is this just too many nested loops and a bad idea?

  • How to stop a while loop with long delay

    Hi everyone,
    I am building a simple program for turning on and off a single Bit.  The task is to turn ON the Bit for a period length T1, and OFF the Bit for a period length T2. T1 is normally different from T2, and can be controlled  by users. 
    Since T1 and T2 can be variable, they sometimes can be very long.
    If I use a Wait function inside a While loop, it needs long delay to be able to Stop the Main program.
    The same situation happens when I use Timed loop.
    Can anyone suggest me how to do this task?
    Thanks a lot.

  • How to stop a while loop which contains a timed loop

    I'm a new hand to labview, and I'm using labviw 7.1, NOT 8.x.  I'm trying to do a measurement, in which the flow would look like the attached file (I have stipped all hardware related components to make it easy to read).  My questions are:
    1. In Loop 3, when the comparison (x>20.85) is true, Loop1, Loop2 and Loop3 are stopped, why it won't quit the while loop (I have wired it to  while loop stop)?
    2. When it is running, I click on stop button, why it won't stop?

    The stop button is read outside of the inner while loops.  So the inner while loops will continue to run until their stop conditions are met.

    It seemed to me like it would, but sometimes it seemed like I had to set change the numeric value one more time before it would.  You have a very odd structure there by placing the event structre inside the while loop with the other loops.  I think you may be running into issues where events are getting queued up in the event structure, or race conditions between when the event structure might execute relative to the other loops.  It is all very odd and difficult to predict all the ways these structures might interact and relative timing.  Usually event structures would belong in their own parallel while loop.  I think you need to rethink exactly what you are trying to do here.  It probably isn't event necessary to use the stop timed structure functions.  A local variable or a notified to pass the "Stop status" from loop 3 to the other loops (or the separate event structure loop to the other 3) would probably be better.

  • How to EXIT the while loop in Event response section?

    I'm writing a program to grab image using a NI card. The application uses the Event structure. When the GRAB button was pressed, it snaps image continually by putting the SNAP function in a while loop. Is there some way to exit the while loop?(Note :The while loop was put in the GRAB IMAGE event response section.)

    edit this event-case AND uncheck "lock front panel until the event case for this event completes".

  • How do i stop a while loop

    I'm new to labview and I'm having a problem stopping a while loop (running windows XP/2000 with the student edition of labview express 7).
    I'm doing a data acquisition program where I'm constantly reading in voltage and comparing it to a set point value, when the input voltage goes above the set point, i want the while loop to stop. How do I do this? I already have an LED going on when the criteria is met, but I'm not sure how to actually stop the loop (i.e. change the iteration value from true to false-i guess). If anyone can please assist me with this I would very much appreciate it.
    I've included my program too.

    Hello Everyone-
    I've just posted a message about stopping a while loop and it was answered accurately and quickly- thanks to LV_Pro and PauloM- thanks much- its nice too see that there are many helpful people out there! Unfortunately, I have 2 more questions to ask of the forum.
    My application is almost completed- I just need to add an elapsed time counter that will tell me how long it took for my LED to trigger (from my set point-i.e. when from 0:00:00 until when my loop stopped).
    Now I've found a perfect elapsed time counter on the NI web site contributed from Mike Hall from Ohmeda Medical- the page is here....
    So my first question is, it looks like I can just extend the while loop box in my 'CO detector... .vi' and paste just the code from the 'elapsed' while loop into my loop and I will be set- but do I need to change my wait until next multiple to be a 1000 too in my program? Probably, but I'm not sure hence the question- or other ideas would appreciated.
    My second question is now that my application is complete (after I add the elapsed time above), I need to exactly duplicate this process for 7 other DAQ inputs (i.e. right now I'm using only 1 of 8 analog inputs on the FP-AI110). So should I make my 'CO detector.. .vi' a separate program (I remember reading something about this in one of the posts earlier).
    Any help is very appreciated.
    Thank you again,

    Hi fais,
    Following through with what JB suggested. The steps involved in replacing the inner for loop with a while loop are outlined below.
    You can replace the inner for loop with a while by doing the following.
    1) Right-click of the for loop and select "Repalce" then navigate to the "while loop".
    2) Make sure the tunnels you where indexing on with the for loop are still indexing.
    3) Drop an "array size" node on your diagram. Wire the array that determines the number of iterations your for loop executes into this "array size".
    4) Wire the output of the array size into the new while loop.
    5) Set the condition terminal to "stop if true".
    6)Drop an "OR" gate inside the while loop and wire its output to the while loops condition terminal.
    7) C
    reate a local of the boolean "stop" button, and wire it into one of the inputs of your OR gate. This will allow you to stop the inner loop.
    8) Drop a "less than" node inside the inner while loop.
    9) Wire your iteration count into the bottom input of the "less than".
    10) Wire the count (see step 4 above) into the top input of the less than. This will stop the inner loop when ever the inner loop has processed the last element of your array.
    Provided I have not mixed up my tops and bottoms this should accomplish the replacement.
    I will let others explain how to takle this task using the "case solution".

  • How do i exit a while loop using event handler

    I have an event handler structure within which i run a while loop for a particular event. I would like to interrupt the execution of this while loop as soon as another event occurs, even if the while loop has not finished execution. I have tried so many ways, the best i could get is exiting one itteration after the new event occurs which is no good for me.
    Any suggestions???

    Instead of having a task while loop in an event case, put your task while loop in parallel with the loop surrounding the event structure. When the event which should start the task occurs, you can signal the start of the task while loop. You could use local variables of references to start/stop the loop when an event occurs. You could also use notifiers instead of variables to pass signals to start/stop the while loop. In general you should have a while loop for the event structure, and a parallel while loop to do the tasks. The parallel loop is controlled by variables or notifiers which are set in the event cases.

  • Code golf: stop two while loops with guaranteed iteration ratio

    In the vein of the Perl tradition, I'd like to see if there's any interest in solving short programming puzzles in LabVIEW. Anyone can post a problem and define the rules for solving it.
    Here's a beginning/intermediate question to whet your "palette".
    With one user-action, how would you stop two while loops such that the ratio of their iterations is the always the same? One concrete way to visualize this situation is in taking measurements: two instruments use the same timing source to take measurements, but second divides the clock down so that it is an integer factor slower than the first. For example, if the slower instrument is four times slower, then at the end of the VI, if the slower instrument takes 100 measurements, the faster instrument has taken 400.
    You may only use vi.lib
    You cannot include any other subVIs
    Your solution must pass for loop1 interval as low as 25 ms

    If folks are interested in this, then let's figure out how to make future problems better. Please post your suggestions and critiques, but only if you also post a submission ;-)

    Multirate Loop Code ‏11 KB

    a) You work with an integer factor of speed. While this matches many application areas, there are still cases where the factor has to be floating point (e.g. 2.5). Additionally, the factor might "invert", so the master loop runs slower than the slave (factor 0.5 for instance).
    It sounds like you're about to post another code golf question. If you think the problem scope is too small, you're welcome to fashion one to your taste. Thanks for volunteering :-D
    Norbert_B wrote:
    b) This example does not take into account that the hardware has to be synchronized with more accuracy than the software supplies (PXI?). If hardware synchronization is required, there are two possible ways:
    - The factor can be included in the synchronization (using PLL for instance)
    - The factor has to be software implemented by data reduction for the task running at the lower pace.
    Hrm, maybe puzzles aren't really your thing after all. You are correct: I did not define every constraint that can lead to a provable best closed-form solution, but that does not prevent people from stating their assumptions and forming creative, well-reasoned, and still correct designs. I overlooked this reading of the description and neglected to add a statement that said solvers were free to add their own conditions. I will do so in the fugure :-)
    If we choose the first of your suggestions, the VI must still retrieve the data at different rates. You can dedicate a loop for each instrument to decouple any jitter and latency introduced by their connectivity or internal operation; this adds some margin of safety when there is thread and driver contention. You can also implement a single counting loop like altenbach and forego the multiloop complexity.
    Norbert_B wrote:
    c) You don't state anything about "what happens with the data". Is this time consuming? Does it introduce additional delay in loop iterations? Is it OK to have data loss?
    I don't know -- you decide, you disclose, and you solve :-)
    In my specific situation, the measurements are time consuming and do add delay (each data "sample" is 5-20 megabytes), none can be lost, and the data must be available for others to analyze later. In addition, the amount of data is saturating the hard disk throughput. If a particular write takes too long, the instrument driver may overwrite a yet unfetched sample, which is unacceptable. I did not add these details to the problem discripton becuase they don't impact the puzzle.
    I don't want to burden people with my situation and ask them to solve my problem: I want to encourage them to bring their intuition and experience to a discussion. This is the design process at its heart: understanding why and how constraints affect your decisions. If a person states the additional conditions they've assumed, readers can learn why, and more importantly, when a Notifier might be more desirable than an Occurance or a Queue more robust than a Data Value Reference.
    The best NI-published advice for stopping multiple while loops ( is laughable (and is the "solution" in my template).
    Would you care to re-approach and contribute to this puzzle? I suspect you have a lot to offer :-)

  • How to stop  after first loop operation  over?

    How to stop  after first loop operation  over?
    I have a loop operation in module pool program.
    After first loop over I want to stop.
    I used the STOP keyword, but it is going to dump.
    Thanking you.

    The statement STOP is forbidden in methods and, since release 6.10, leads to an uncatchable expection during the processing of screens called with CALL SCREEN...
    As they said above, use a EXIT statement to fix this DUMP...
