• value chain control event does not trigger change

  Hello

  I am trying to scan a barcode with a barcode usb HID scanner. I use a structure of the event to detect the change in the value of a control of the chain. When I scan the barcode, the chain control updates on the front panel, but the event does not fire until I left on my mouse on the front panel. can someone help? See attached vi

  Your barcodes are probably fixed length. When you get an event, check the length. If it corresponds to the length of the barcode, then process the data, otherwise wait for more characters.  This can be treated very quickly in the case of the event.

• Cancel the registration of events does not not to change value

  Cancel the registration of events does not seem to prevent the change in value of firing event.

  I've attached an example of change that disables the mouse enter and exit events to include the value Change event.

  You use the standard event, not the dynamic one (note that the Boolean value does not have the <> ).

• APEX 5. Dynamic action on the CHANGE event does not work after applying the filter on IR.

  APEX 5.

  Dynamic action for the CHANGE event does not work after applying the filter on IR.

  Event: Change, selection Type: jQuery Selector, jQuery Selector: td [header = 'abc'] entry

  Real action

  Selection type: jQuery Selector, jQuery Selector: td [header = 'abc'] entry, Action: run the Javascript Code

  Is TI WHEREAS behavior?

  I know, I can work around this problem by using the Refresh event and javascript, but I prefer DA and if possible Change event.

• Why when I choose a photo in the library grid view it does not appear in the window to develop up to selected in the Filmstrip below?

  Why when I choose a photo in the library grid view it does not appear in the window to develop up to selected in the Filmstrip below?

  It was the strangest thing, but I think I solved the problem. Use the CC version 2015.1 on a Wacom tablet using Win 8.1 and inadvertently from the same batch of photos, I had downloaded twice and it was very confusing because it did not prevent the duplication of files, but the files where not really there. I didn't know whether to remove or delete the files with question marks for fear of destroying a link or something so merged files and now everything works as it should, once chosen in the library that the photo appears in develop mode.

• Event does not work when I have my variable of variable mutual FUND!

  Hello

  I programmed a labview vi to add a field to a list view when a Boolean variable value is changed. I used a case Event (value change event) structure to determine if a variable value is changed, it works when I force the Boolean control with my mouse click, but it does not work when the value of the variable is modified by the mutual FUND. What should I use instead?

  Value change events are based on the interaction of the user (or the same ejection programmatically based on the value property node (signaling).)  It is not based on a control change via a regular, variable property node local, terminal or any other connecito0n programmatic or binding.

  You must simply query the variable and determine when it changes.  In this case, you can then use the node value property (signs) in the case of event fire.

• Structure of the event does not not at the exit of a Btn dialog box

  Hi all

  I have here a simple VI. I want to blow a One button in the user dialog box. I want VI to wait until the user clicks on the OK"" button. When we click on the OK button the VI should pop another dialogue a button and stops when you press the Ok button. The VI does not stop. The value change event is not captured by the structure of the event. Can't really understand why.

  What OK button you are wanting to trigger structure of the event?

  1. as you have connected it the case of the event is related to the OK INDICATOR on the front panel.  You don't have an OK button on the front panel. The OK button in the dialog box is not easily accessible to the structure of the event.

  2. programmatically change an indicator does not raise an event to change the value.

  3. you can use a Value property node (signaling) to trigger the occurrence.

  4. There is almost always a better way to do what you want to use an indicator and a value (follow the signs).

• Filter KeyDown event does not.

  The attached file includes a sub - vi (drop-down) with his code wrapper isolated from the rest of the program and used as the main vi (drop Ring).

  I currently have three ways to "exit" from the menu drop-down; both labour and the other does not. Who is the keydown event. It is currently set by default so that the ESC key, but I don't have any joy with other keys either.

  Could someone check my code to see what I could do wrong? For the moment, the keydown event never seems to happen I was rather confused as to why.

  There are a few controls 'extra' on the front of the main vi, but these are mainly for debugging purposes.

  Attachment: (LabVIEW 8.5)

  • Drop Ring - main VI
  • Drop-down - menu Sub VI

  Try to set the menu Subvi to "modal" in the customized appearance properties. Now seems to work perfectly.

• structure of the event does not record local vars

  I have a gif of a FPGA based topology I want to show some telesignalisations in.  As the user clicks on the Boolean, vertical lines appear and disappear as they click on it again, showing the current topology of closure.

  To save resources, I opted to use a structure of the event.  So far I put it for internal RX_FAC and RX_TERMXCO4AU you see at the top left of the image.

  A single loop of RX and one TX closure may be on at the time, so one of the first things that happens when the user clicks on the Boolean value is that it defines the values of all other Boolean in the same row of fake, thanks to the use of local variables.

  The problem is - the structure of the event runs only when the user actually clicks the Boolean true or false value, but not if the boolean is false through the use of a local var.  In other words, let's say I RX_TERMXCO4AU true and false RX_FAC.  If I click on RX_FAC to set it's true, then you will notice RX_TERMXCO4AU goes dark/false and RX_FAC lights.  So the value of RX_TERMXCO4AU has changed, but associated with the structure of the event RX_TERMXCO4AU does not run (that's why the vertical line between RX_TERMXCO4AU and TX_FACXCO4AU remains).

  This will make a lot more sense if you run the attached simple VI.  Right now, events exist for RX_FAC and RX_TERMXCO4AU, but it is sufficient to explain the problem I think.

  Any help is appreciated.

  The structure of the event is for events generated by users.  Writing to a local variable is a programmatic change.

  You want to do is write your value to the Value property (Signalling) of the Boolean that will change the value and raise the value change event.

• UserChanged event does not run

  Why the event UserChanged without executing when the user is changed with the IEngine.CurrentUser property in an operator interface?  I noticed that it will run when the connect/disconnect methods occur, but not when it is modified directly.

  Also, is it possible to force this event programmatically, so runs the code in the callback associated with this event (such as a work-around?).

  Thank you

  Paul

  TS 4.0.1

  LV 8.5.1

  Paul,

  for the event to not be fired because IEngine.CurrentUser is a property of the engine and the event is controlled by the Application Manager. Therefore, changing the value of the property does not create the event on its own.

  If you work in a user interface, it is recommended to use the Manager commands; the application Manager provides a method of "Login":

  Connects the user by running the front-end reminder LoginLogout. This method does not wait for the callback to run. Use the ApplicationMgr.UserChanged event to determine whether the connection was successful.

  The downside is that the front-end LoginLogout creates the default value of connection dialogby. If you do not want to have this dialogue, you should consider to replace with your own front end. But please do not change the default reminder, but substitute using the directory of users!

  hope this helps,

• 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!

• Structure of the event does not clear the queue after his release from the Subvi

  OK I'm not sure if this is a stupid question or not...

  I was trying just a few tips and stumbeled on this problem...

  So I created a sample (not exactly)

  In qqq_Main.vi just press PressMe

  (it opens a Subvi qqq.vi)

  There are two buttons to stop "Alt1" and "pylone2".

  To close the Sub - VI press either on "pylone2".

  or press "Alt1", then "pylone2".

  with the latter method of the value of closing change pylone2 is registered outside the while loop and after the closure of the Subvi should not it be erased? (Or should manually clear us it?)

  For this reason not clear, the second time I press 'PressMe' change the value of pylone2 even goes off before you press anything

  I can't look at your code at the moment, but according to your description, it seems that the system works as expected. I guess you do a completely static record of events (open the event configuration dialog box and select the controls and event).

  The first thing to clarify is your use of the term "registered". In this case, it's a problem, because the registration in the context of the protests means asking to receive the event when it happens.

  Now that you know it's important to understand where the recording is happening, because that's what determines which events are stored in the queue. When you use this type of static record, registration happens from the VI the event structure is in run mode (Note: this does not mean that the VI is actually running, but just that it's the of running or reserved for the race) and the cancellation of registration only happens when the VI mode of execution. Who is right for which you get the events in the queue of the previous run of the VI - the VI is still in run mode, then the event is added to the queue and still waiting in the queue until the structure of the event to run again.

  You can work around something like that by switching to dynamic registration of events, where you can unsubscribe to empty the queue at the end of the VI, but requires more code. Also, in 2013 LV there are a few features added to events that could allow to do this statically (I don't study all the additions, so I don't know if this is possible for static recording).

  There is a good presentation on the events of NIWeek 2013 by Jack Dunaway. You can find details of how to download the video here - http://lavag.org/topic/16091-ni-week-2012-videos/

• EventLogger events does not appear in the event log Simulator

  So, I was more than a little frustrated with debugging Widget applications and decided to help me a bit.

  I've created a Widget extension that connects to System.out and the EventLogger BB using:

  Logger.Java:

  public class Logger {}

  public static final String APP_NAME = "AppName";
  public static final long GUID = 0xb50dd37e31148effL;

  public static enableLogging() Sub {}
  If (EventLogger.register (GUID, APP_NAME, EventLogger.VIEWER_STRING)) {}
  out ("recorder active.");
  }
  else {}
  ("EventLogger record has failed.");
  }
  }

  /**
  * Prints System.out and event log (if enabled).
  */
  public static {Sub out (String msg)
  String message = formatMessage (msg);
  System.out.println (message);
  log (message);
  }

  /**
  * Prints in the journal of the events with the ALWAYS_LOG level.
  */
  Public Shared Sub log (String msg) {}
  logEvent (msg, EventLogger.ALWAYS_LOG);
  }

  private public static Sub logEvent (String msg, int level) {}
  If (EventLogger.logEvent (GUID, msg.getBytes ())) {}
  System.out.println ("EventLogger.logEvent succeeded.");
  }
  else {}
  System.out.println ("EventLogger.logEvent failed.");
  }
  }
  ...
  }

  The Widget extension works.  I can not even log JavaScript stuff :

  somewhere in file.js:

  Logger.log ("it is JavaScript!");

  as seen by the Eclipse debug console:

  AppName [2010-09-24 12:01:33.609]: active recorder.
  EventLogger.logEvent succeeded.
  AppName [2010-09-24 12:01:33.625]: it's JavaScript!
  EventLogger.logEvent succeeded.

  RIDDLE ME THIS: WHY are the messages NOT sent to the event log Simulator! (9550 or 9800 > tools > Show Event Log does not show my posts.)

• Send the event does not

  I am trying to send my data class event when the data has been changed using the logic below. I've reproduced my problem below in a sample application based on one I found on a blog, I've created. I use a click on a button to call the dispatcher of events for the event class, but the main class of DispatchEventDemo does not seem to raise the event.

  When I put an instance of the DispatchEvenExample class in the FormWithButton class, it works but only within the same class (if uncomment the addEventListener method in FormWithButton).

  What I'm doing wrong? Is it because I'm dealing with the wrong instance of the DispatchEventExample? I think I need an observer model configuration...

  package
  {
  import flash.display.Sprite;
  import flash.events.Event;
  import flash.events.MouseEvent;
  import flash.text.TextField;
  import flash.text.TextFieldAutoSize;

  _dispatchExample = new DispatchEventExample();
  _dispatchExample.addEventListener ("Will", onEvent, false, 0, true);
              
  myForm = new FormWithButton();
  this.addChild (myForm);
  }
  private void onClick(e:MouseEvent):void
  {
  trace ("Click");
  _dispatchExample.sendEvent ();
  }
          
  private void onEvent(evt:Event):void {}
  trace ("_dispatchExample dispatched an event");
  }
  }
  }

  private var _timer:Timer;
  public void DispatchEventExample() {}
  }
  public function sendEvent (): void
  {
  dispatchEvent (new Event ("will"));
  }
  }
  }

  }
  }
  }

  I think what you need here, it is a singleton class. you create two instances of the object and add the listener to these two different instances. so when an event is being shipped via an instance your application is listening for the event to another instance then its never read correctly.

  Here is a link to a post that jtegen posted there on singelton classes:

  http://supportforums.BlackBerry.com/T5/Tablet-OS-SDK-for-Adobe-Air/going-back-to-main-page/m-p/71241...

  in this case, the singleton is the DispatchEventExample class.

  using the method htat and attach your headset to the same instance, it should do what you want it to do. Good luck!
