Value change event, be it be programmed to trigger only when the USER changes the value?

The structure I set up is the following, I have a control in which the user chooses a value when they choose this value, the value change event takes place setting in the device. Then I am bed in unit values and display them in this control via a property node.

My problem is that whenever I read back a new value in the control, he takes this as a value change event and resets the value within the system, is it possible to make this event don't move when the user changes the value?

Yes!

My thoughts are that you use a Value property (signalling) node to display for the control. That will trigger another call to event.

Use the NO signs of property value node or a local variable.

Your postal code, if this isn't the case, then we can help you understand what is happening.

  • How the LED lights up when a threshold is reached, then turns off only when the value does not reach the threshold for a while?

    Hi, I want to write a program that can turn on the LED when a range of value, this is the threshold and only when the value does not reach the threshold for a period of time, say 5 seconds, then the LED will turn off, otherwise it will remain. How can I achieve this in labview? Can someone help me? Really thanks!

    I assume that you use a while loop to keep the updated value.

    Add a record to offset to your looping it initialize with a U32 (time in ms)

    Add the registry to offset to your loop that keeps the previous value of your bool

    When your reaches the threshold value => the light and set the current time in your shift register.

    In the next iteration of the loop weather check value is still above threshold

    => Y-online previous set to true?

    => Y-online the next iteration

    -Online N => turn switch on and set the current time in your shift register.

    -Online N => subtract the time current less time shift record-online more then 5 seconds?

    => Is => keep turning on

    -Online N => turn given

  • Folder "Programs and features" shows the installed program, but is blank when the file size must be listed.

    Original title: what does it mean when you have a program installed, but when you open the folder "Programs and features" it shows the program installed but remains empty where should be the size of the file?

    Shows information for the installed program, including the NAME, PUBLISHER, & INSTALLED ON (DATE), but under the info column of SIZE empty sound while 98% of all my installed programs show how much KB or MB "and specific program installed. Seems to lack the SIZE info only on any one of my Adobe programs and a few select other random programs?

    Hi AlinaSporl,

    The size information is reported by the uninstaller for each program component. A program of uninstalling programs will not report this value, so the size of the program does not appear in this list.

    Another way to get a close estimate of the total size for an individual program is to check the properties of this installation of programs parent folder in C:\Program Files.

    You can read the following article and check:

    How add/remove programs is the size and other information?

  • windows program will rearange themselves when the monitors are in mode 'sleep' - how to stop windows switching screens

    IV has 3 screens on a map via display port adapter and a 4th on a second card in order to have a 1 on top of three parameters.

    the computer itself does not sleep because I have servers running but I put screens on standby after 10 minutes.

    for a long time, all screens would go to sleep and wake up without any problems... in the course of the last months, 2 questions.

    1. once the monitors to sleep and no consistent time 1 monitor wakes up enough to show the backlight, but no display... wake up ok and sometimes screens dislocated.

    and

    2 when the monitors have the power save / standby mode, some of the Windows I had open will have been moved to different monitor as monitors have been disconnected or "detected" numbers have changed and I saw the change number several times as well, but not always.

    I say some because I have 4 windows open on my left most monitor and 2 of them end up on my right monitor after the glitch.

    Sometimes things on my low Center {main} will end up on the top of the single monitor page.

    no rhyme or reason... a few days no problem at all don't wake up and everything is where it should be and all the screens have slept through the night

    Hi experts Adf.

    I have a usecase where a lov and a field date is in a table. Each time, I have a lov selects for the first time, and then save the button. Then change date is get inserted with null. (it's fine).

    Now when I change the existing value of the lov and then clicking on save, then the modified date is updated. (it is also very good).

    Scenario question: suppose that in the first row, WE show dropdown because it is saved in the database and change date as null.

    However when I try to change the value to lov ' sales and do not click Save. Now, once I select IT and clicking record. In this case, change date is updated.

    Idle screenplay: Change Date must be updated if there is no modification.

  • Acquire the values only when the digital output is high.

    Hello

    I work with test of transistor, whose door is controlled by the digital release of USB6289, related to BNC2120.

    Test plan:

    Door 1.transistor is enabled for 5seconds, with P0.0 for example

    2. then, everything remains off for 1secondes.

    3.p0.1 is used as digital output to activate the circuit passing him curent through in the opposite direction, P0.1 goes high for 3 seconds, PS: Gate is off.

    4. the same cycle repeats again.

    My question is to store values to the output of the transistor when P0.0 and P0.1 goes high, and these values should not change until my digital outputs respective again go high.

    I can access transistor by continiously read out my power supply values.

    and in the State off I want to read AI0 because at that time, my power supply is off, so that I can activate the circuit to pass the current in the opposite direction.

    Again, my question is to gain the output through power value when P0.0 is high and store them until the transistor turns on.

    and even for P0.1, acquire the value of output through AI0, when P0.1 is high and store it until it goes high again.

    Hopefully, I'm able to explain my problem clearly.

    Please help me.

    Think about what States (object:statemachine and determine when to use sequence Structures) do you want from t0... t(n-1), IF DAQmx generates outputs and/or inputs are absorbed and what needs to happen (event timed out), before move you on to the next 'State '.

    type def 'enum' with your different States:

    • initialize
    • wait (the user initializes times (sec) set for States, or whatever and presses button 'Start')
    • T0 (generate DigOutputs, store acquired data AnalogOutput (string output number) the register shift, before moving to the next State > user 'set time' must elapse (Note: the wait function allows you to control the rate of execution of loop and allow the CPU to respond to external events and system tasks and avoid using wait functions at the same time an operation of software...))
    • ...
    • t(n-1) if ' end (made requirement) "> goto 'stop', ' another (not requirement not)" > goto regardless of 'State '.
    • stop
    • write a text file of data (string).

    Hello

    I want to ask about the select oracle ADF that many shuttle.

    Recently, I want to create a shuttle a lot with the pre value is set in the right box, select. When I try to set the value of the shuttle to select several properties. The shuttle many select transformed into an object as input like the image below text

    the method that I put in the value property is like that

    public list < BidClassification > getListBidClassificationTaken() {}

    finalClassification = new ArrayList();

    The OperationBinding class method = ADFUtil.getMethodBinding ("retrSupSupplierClassificationFindAllBySupplierId");

    method.getParamsMap () .put ("supplierId", getSelectedSupplier () .getId ());

    List < BidClassification > finalClassification = method.execute () (list < BidClassification >).

    Return finalClassification;

    }

    the method that I use to set the position data is like this

    public list < SelectItem > getListBidClassification() {}

    retval = new ArrayList();

    The OperationBinding class method = ADFUtil.getMethodBinding ("retrBidClassificationFindAll");

  • CS6 AIR flash device emulator throws off events when the sensors are changing

    I'm developing an application in Flash CS6 targeting AIR 21.0.0.176 for Android.  I've implemented the NativeApplication.nativeApplication Event.ACTIVATE Event.DEACTIVATE listeners.  These work as expected when the Android device is running standalone or if I am debugging via the interface to CS6 USB. However if I have a deployment on the simulator of premises, whenever I use the Simulator interface to generate a change in the accelerometer or location, the application then receives a DEACTIVATE event.

    It's difficult troubleshooting because on my manager to DEACTIVATE event by stop all the interactive features in the application.

    Any ideas please?

    I guess only the two ways to work with the configuration of the listener. It is not a bug, however, the window of the Simulator is a different application, when you select you have disabled your app, it did the right thing. But in this case, you don't want him to do the right thing, then use the work around.

    The report does not appear but. I checked the session. It has the value of the selection list and the page is submitted as but the report is not displayed.

    ASK is disabled before the exposure treatment page unless it is set in a branch or a URL, this is why it has no value when they are referenced in your State in the region.

    Set the attribute request in your branch for & request to make available at the course to see the page the current value of the demand for treatment.

  • While the loop does not stop when the two values are equal using equal to comparitor

    Hello world

    I have a really, really strange bug. I have a LabVIEW VI that change a chain on a power supply. I have a start and a stop voltage and use a while loop to increment the device. For example if I want to scan from 1, 2V to 2.2 V in 0.2 V incremements, the program will end when "The current tension" = "stop the tension." And it works very well!

    However, when I start - 3 V and want to stop to say-0.8 (new in 0.2 V incremements) the program does not stop when "The current tension" = "stop the tension." I checked with the probe close to what should be the end of the race and - 0.8 V goes both of the entries ' equal to ' comaprison operator, but that his can't trigger a real result.

    It's very strange for me. Espeically as if I'm going - 0.8 V to-2 V but decrement of-0.2 V, the program stops correctly!

    I am very confused!

    See you soon!

  • Capture of key press on when the focus is not on VI. (event does not work).

    I have a VI and found similar in Forums. I need to get the key to the bottom of the event, when the focus is not on VI.

    I have attached the VI found in the forum. Try clicking other windows, for example on the diagram of the VI, when VI is running and check if it works. The answer is no, it does not work. When you press a key, the button led should change its State, but it is only when the focus is on the face before of the VI. The question is how to control the pressure of touch, when VI is reduced or inactive. Is it possible to get the key to the low or any other similar event, when emphasis is placed on another application, not the VI?

    Take a look at the 'Connectivity... of input devices' menu.

    For an example, open the example finder and search for 'basic demo of entry. " It should give you some ideas. Good luck!
