value of property not generating a signal event node

I have a sample program that uses a property node > Value (Signaling) to generate an event.  The property looks like this:

When I create a VI to do the same thing, the property node looks like this:

I click with the right button on the Boolean control, create, node, value property (Signaling) to create the node.

My VI does not generate an event when a value of TRUE is passed to the property node.  Is it possible to change the Boolean Data Type?  What is the problem?

If the data type of the property value node does not resemble boolean (i.e. purple instead of green), you must change the mechanical action of the Boolean because it is currently latch action. Change the mechanical action to switch the action and you should be OK.

Also note that a value property (sgnl) fires the event to change value unconditionally, even if a new value of the former are the same.

(If you want to be able to raise Boolean lock action events as you describe here, consider a vote for this idea. )

  • DAQmx property in event node can % 27T be update

    I want to update the node property of DAQmx event to update dynamically the value, but only 1 of the 2 property node can be updated "DAQmx is task Done.vi", the whole could be triged normally.

    As shown in the photo below: report cyclic case can be triged and run, but the value of property not upgrade vi DAQmx. well frequency one normally.

    The answer is probably more strange than you expect.  It turns out that the two impulses of the synchronization frequency and duty cycle parameters are also privileged.  (I believe that the same kind of asymmetry applies when you set a pulse with high and low time).

    Frequency Gets the privilege in this sense the pulses of timing is changed only when a frequency value is written.  In order to change the operating factor, you need to get a property node DAQmx Channel, expose the properties of duty cycle and frequency and write to both of them.  You don't need to change the * value * you write in the property of frequency, but you * need to write for her.   Given that written node property follow these up and down, it is important to have the property of cyclical report above the frequency property.

  • Value of signalling event

    Hi guys,.

    I'm trying to raise an event using "Value traffic" and I hit a few snags.

    I like to read the logic inputs permanently and I wanted to raise an event, if there is a change on the logical signals.

    What I did is that I read that the logic of signals initially to get the default status and to review once again the logic of signals inside the loop timed in cases waiting for signals of change.

    However, the Dungeon of the event triggering even there is no change of signal.

    Any advice?

    Concerning

    Ray

    Callin a value property (sgnl) always triggers the associated event, even if the actual value remains even thre. You need a feedback node, comparing current and devoid of values. Place the property in a deal signalling, so it will run only if the values are different.

  • SwipeDown event is not generated.

    In my application, I want to display the application on one menu to the bottom of the event. When I add the following code to my application on device beta1 (10.0.4) I am able to do swipeDown() event, but when I run the application on beta2 device (10.0.6) swipeDown() event is not generated. After a search on the forum and release note I just know that it does not limit the swipeDown() event is not generated.

    URL for realeasenote: https://developer.blackberry.com/cascades/download/releasenotes/ and number: 5347148.

  • Script error: property not valid value operation

    (in FormCalc)

    I have a form with multiple pages.  The first two are a graph and the other 8 diagrams.  Diagrams have fields of number to the entry measures taken from an inspection process.  The graphic form I have a button to fill in the chart with information from diagrams.

    The click event of the button first retrieves the information from the diagrams and transfer them to the chart.  He is then supposed to change the font color depending on whether the readings are within limits (black for good, red for the worse).

    However, when I go in the preview PDF tab, enter test data in diagrams and click populate, I get an error that I don't know how to fix.  I was not able to find something on the Internet about it.

    Any help would be greatly appreciated.  Here's what's on the screen of the error:

    Script failed (language formcalc; context is)

    XFA [0] form [0] .topmostSubform [0]. LHChart [0]. Button1 [0])

    I found the solution to my problem.

    I had the code in the target fields as well as the button trying to change color of font, based on imported figures.  I deleted the code in the target areas and leave the code in the button field and everything worked right.

    In your function mouseDownHandler target you 'e.target.loader', however, e.target is a Loader and Chargers have no property loader.

    private void mouseDownHandler(e:MouseEvent):void {}

    var my_thumb:Loader = Loader (e.target.loader);

    Try just "e.target" instead since this should be your code is looking for.

    var my_thumb:Loader = Loader (e.target);

    Although you might find you need to use "e.currentTarget" instead since e.target can point to the content of the loader instead of the charger itself

    When you set which_balloon to line 3 of your code, you set it to an empty string. This will type the variable as a string. The strings cannot have a property there.

    What you probably want to do is type your which_balloon to the same variable type as some one and two and three are.

  • leads the value change in the structure of the event

    Hello

    Please the the VI attached.

    I would like to know what event triggers when the value true or false of the changes led?

    In the case of structure above the structure of the event, the values of true or false of the led are changed.

    From the change, the analog output for Acquisition Card changes. However, the change event of the value in the structure of the event never fires, I know that I run the Vi with the selected highlight enforcement tool.

    Thank you

    Venkat Rao

    Changing the value in an event structure occurs only if one of the two following situations occurs.

    1. the user who modifies the control on front panel.  That may not happen since these LEDs are indicators and does not control.

    2. the program writes a value of property of the Value indicator/control (signalling) node.  Writing to the terminal of the indicator, or the local control variable / indicator not fire the event.  Given that you do not use value property (signalling) nodes in your program from this moment, won't happen either.

    Note that the value change event is a bit misnamed.  The change event is triggered, even if you do not actually change the data.  So if your LED is currently worth, and you write a True Boolean value for the Value property node (signalling), the event always fires even if you're not technically change the data.

  • Can I 'read' a control value that has not been committed?

    In short, I would like to specifically to bypass convention of LabVIEW which is a value only committed when the user moves the focus, press the button enter, click on a button to increment, etc..

    My specific scenario is I want to respond to button Up/Down/whatever of the events for a given control and enter the value so I can update the graphic interface in real-time as numbers are entered.

    I had thought about using the "Selected" the reference FocusObj property to remove the focus temporarily to force the value to be committed, but it seems to do nothing, at least not the way I use it. I also tried to use this property to choose something else entirely before selecting the original order, but once again, nothing.

    I imagine that an XControl MIGHT be able to do something like that, but I will abandon the effort before I'm dipping my toe into these waters.

    TLDR: Is it possible to cheat and capture the contents of a control, while the user is still typing in there?

    In addition to what nathand said, it is perfectly correct.

    If you need capture an event in the event structure, instead of 'Change of value' you better to handle the keydown event and take the property Numeric.Text for the property Value will not be changed, but you will have access to what is indicated on the control.

    If you do what johnsold says, then the value will be updated after each character, this only applies to controls of the channel.

  • How to trigger the value change in the structure of the event

    HII everyone, like the title, how should I trigger the value change event to display a message... Here is my connection... I want to trigger structure of the event to bring up the subvi, when the flame and the led are TRUE State... I have using the node property, but still not able to run event structure... How should I connect? Thank you very much...

    There are several ways you can do. First of all, you need to configure your sub - vi while he does everything you want when you run (in the properties of vi, top most window for example) and to make sure that it closes completely when you're done (when you click on the 'OK' button, for example).

    Spend you need an asynchronous call to the subvi. There are several ways to do so. My favorite one below. You go in the palette under 'Application control' and select a static reference VI. I like this approach because it keeps track of the way subvi for you, as long as the subvi is in the same project. Then, drag the sub - vi on the empty square which will be changes to your sub - vi icon. Then, you connect to an invoke node in the same palette under and select run VI. "Wait, that 's" set to false and the main VI will continue to function after the start of the vi of Sub. Together "Auto Ref" is the best way to go. Otherwise, you will need to follow the sub - vi reference and shut up yourself when you are finished.

  • How to change the value of string clustered, to implement using the node value of property instead of writing directly on the flow of data or using the variable

    new to labview :-) and I have a problem when I want to change the value of a string in bunches, and I want to implement this using the node value of property instead of writing directly to the stream or by using the variable, enclosed is the picture.   No matter, I have change in cluster (control) or value of Popery out (indicator) cluster, the value (sensor 7) dataflow keeps unchanged even I gave the new value by value of property node. Thank you to give me some advice about this.

    Hi GerdW

    Thanks a lot for your answer. The reason I'm stubbornly tring to break the flow of DATA is: we have a test system that have about 100 screws, they have a few connected flow, some of them will be unbundling a cluster dataflow chain to check the value in order to make the different cases.  Now I want to insert user event by changing the control and influential cases during run time.

    As I initially uses a global variable (to control cases) instead of unbundle string data flow, it works well.  But then, I found there are a lot of screws that are using the string unbundle.  One of the 'lazy' means, I tried is to change the value via the property node (because that way, I did not need to find all the places where using the unbundle string and replace them with the global variable), then I noticed a problem with "dataflow", the value in the stream of cluster in fact will not be changed by changing the value of the property node.

    I did a test with VI simple (like the picture in last post), and after reading your advice, I tell myself that I need to understand the concept of "DATAFLOW" in labview, it seems that my "lazy" way can not work in this scenario.

    I have attached the criterion VI here, have you furthur suggestions on what I can do in this case?

    If your textfields are named (you went for each text field properties and gave it a unique name) you can use the Manager of Focus see IFF it has focus to set the selection to the end.

    In the case of initialization of your VI main, you're going to initialize the FGV Subvi error.  But you can't give the refnum of user events to store in the shift register.

    When you use this FGV later, it uses the empty refnum into the shift register and sends that to generate the user event, and it gives an error.
