• How to raise an event when a file is created.

  Hello!
  I need labview wait until a file is created in a certain folder (by the other program) and then to perform a task.

  Is this possible?

  I have no idea how to implement it.

  Thank you!

  Use the file Info feature.  From time to time, repeat until you do not get an error.

  I saw an example somewhere where someone used .NET to get an event when a file has changed.  I have no idea where he is or how it was done however.

• How to raise an event when the user have clicked all the buttons (in random order)?

  Greetings,

  I want to trigger an event (frame 2 goto and stop) after all my 3 user buttons were clicked in no particular order.

  I have 3 buttons on the stage, image1. (instence names: MCBlue, MCRed, MCYellow)

  How can I write my code?

  Here's what I have, but it does not at all. I'm so confused.

  I thank very you much for your time.

  [code]:

  import flash.events.Event;
  import flash.events.MouseEvent; 
  
  stop();  
  
  MCRed.addEventListener(MouseEvent.CLICK,redReady);
  MCBlue.addEventListener(MouseEvent.CLICK,blueReady);
  MCYellow.addEventListener(MouseEvent.CLICK,yellowReady);
  
  function redReady(event:MouseEvent):void
  {
            MCRed.MouseEvent.CLICK();
  }
  
  function blueReady(event:MouseEvent):void
  {
            MCBlue.MouseEvent.CLICK();
  }
  
  
  function yellowReady(event:MouseEvent):void
  {
            MCBlue.MouseEvent.CLICK();
  }
  
  
  var buttons:Array = [redReady, blueReady, yellowReady];
  var sequence:Array = [];
  var correct:int;
  
  
  addEventListener(Event.ENTER_FRAME, gotoFrame);
  
  
  function gotoFrame(e:MouseEvent):void {
            if (buttons.indexOf(e.target) == sequence[correct]){
                      gotoAndStop(2);
            }
  }
  
  

  If the buttons are movieclip symbols, then a way to solve it would be to set a property of each button to be true, when everyone gets clicked and then have a function that you call who checks this property for all buttons.  When all the true test is when you switch to the 2 structure.  Something like...

  import flash.events.Event;
  import flash.events.MouseEvent;
  
  stop();  
  
  MCRed.addEventListener(MouseEvent.CLICK,redReady);
  MCBlue.addEventListener(MouseEvent.CLICK,blueReady);
  MCYellow.addEventListener(MouseEvent.CLICK,yellowReady);
  
  MCRed.clicked = false;
  MCBlue.clicked = false;
  MCYellow.clicked = false;
  
  function redReady(event:MouseEvent):void
  {
            MCRed.clicked = true;
            gotoFrame();
  
  }
  
  function blueReady(event:MouseEvent):void
  {
            MCBlue.clicked = true;
            gotoFrame();
  }
  
  function yellowReady(event:MouseEvent):void
  {
            MCYellow.clicked = true;
            gotoFrame();
  }
  
  function gotoFrame():void {
            if(MCRed.clicked && MCBlue.clicked && MCYellow.clicked){
                      gotoAndStop(2);
            }
  }
  

• How to raise an event when all the sounds in a soundchannel ends

  I have a soundchannel and I play a lot of sounds in there, but I need the fulfillment of any audio file within this channel to be followed by a two second wait, and then trigger an event. How can I do this?

  When the SoundChannel object is complete, there is a soundComplete event gets dispatched (Event.SOUND_COMPLETE).  Its assign a listener for the event.  If you need more information, the Flash help documentation has everything.

• Raising an event based on digital input? Treatment of a condition of emergency stop

  I'm working on a test sequence into LabVIEW.  I have a security which I am followed by a digital input the relay status, and I would like to pass to my failed state that I am in a State of emergency.  (In my case, this happens when a barrier is broken or emergency push button is pressed).

  It would be easy to do if I could use a digital input to trigger an event.  However, this doesn't seem to be possible.  I tried bind my digital input to a control, and then follow the State of the control as an event, but that doesn't seem to work.

  My main problem is that I can be in one of the stages of test 5 seconds approximately.  So far, I have not found a way to out or interrupt this step if my digital input changes state.  I can get it to transition to the failed state after the step in progress, but I want that it to transition immediately when the safety relay is broken.

  I've attached a picture that shows the basic structure of my program.  The actual program is much more complicated, so I hope this is enough information to get started.  I have stops in each loop attached together with the help of a subvi, which basically returns a Boolean TRUE if you press the 'stop' on the operator interface (it is one of the events of my structure of the event).

  

  It seems that it would be a fairly common situation that there must be some answer I'm missing.  Can anyone help? Thanks in advance...

  You need (somewhere) a loop that monitors the digital status and can detect the transition Fail.  The timing of this loop of 'surveillance' apply to how fast you can respond to failure.

  But now you need to trigger an event when this happens.  When I started programming in LabVIEW, I learned on the events of signs of value that could trigger programmatically a value indicator has changed.  However, a few years later I learned the user events, a more flexible method for generation "software interrupts' who have a number of advantages over value of signage.

  I don't know if you are looking for using LabVIEW or LabVIEW examples user events you'll find a good explanation for how to use these (use the Help Index, and then type user name).

• Intercept touch green application event when the device is locked

  Hi, I'm new to blackberry. What I want is I want to take a key event (green or red button) when the device is locked and do specific tasks in my application that runs in the background if this button is pressed. Is this possible? How can I do?

  Just to be 100% accurate, it is possible for a keyListener (look to the top of the class) to pick up some events even when running in the background.  It can be different events when the device is locked.  Indeed, the events may be different depending on whether the "locked" screen is currently displayed or not. And the entire lot is dependent on operating system level, in other words, the same device running two different levels of OS will possess differently in terms of what keys can detect a listener in the background.

  So if you have a BONE and a specific device, so it might be something you can do, especially if it is an older operating system.  However if you try to create something that works generically, then know that I've tried and failed!.

• Generate the event when the focus lost

  Hello

  is there a way to capture an event when a textbox control lose focus?

  Thank you.

  Yes there is, just create an event filter button on this control of the chain and when a tab is entered you trigger your (re) load event. Or you can set a keyboard shortcut for this field (such as ctrl-D) to define a group of controls to a default state.

  What are the complications that would keep a button 'Load' of work? Maybe things are too complicated and we need to simplify things a bit.

• Raising an event from multiple tabs?

  Hi guys, first post so please be gentle! I'm doing something that I believe should be simple, but I can't find the answer anywhere, basically, I want to raise an event to an event of the housing of the different tabs in a tab-based USER interface. For example, I want to have a button "Configure DUT" on two legs, but cases that a single event should be necessary. I guess that one obvious way to do it would be to have common controls apart from the section of the tab, but I'd rather each tab to be autonomous, so I can put the controls in a better way depending on the task in question.

  In the dialog box change events, you have a button 'Add an event' with a blue + sign. This allows to register for more than one event.

• What is the event when back to summon the Manager

  Hi, I use Invoke Manager to play the video

  What is the event when the invoke handler is close / back-> for my application.

  (I want to analyze how long this user read this video)

  Thank you

  I do not know what past all I KNOW the app called is not informed of which invokes this past that stage of the initial call, therefore no mechanism is a reminder when the application is closed.

  Obviously if you wrote the video player yourself you could invoke back or set up signs saying closed process.

• How to register for an event when the device is connected to the PC in USB mode or sync

  I develop application on blackberry with phonegap.

  I want to hear event when the BlackBerry device is connected to the PC by USB MODE or sync.
  I saw mediagallery and applications Filemanager showing the dialogue that the application cannot be used when connected to the PC in USB mode.
  I want to display dialog similar to my request.
  Can anyone please help on how to do it.

  I saw blackberry webworks API

  public static Boolean blackberry.system.isMassStorageActive)

  who says if massstorage is active or not.

  But I can't keep on request this API every time. I'm looking for an API that gives me the reminder.

  Can you please help.

  On the side of Java, this can be done by implementing a FileSystemListener and the rootChanged method:

  public void rootChanged(final int state, String rootName) {
      if (rootName.equalsIgnoreCase("sdcard/")) {
          if (state == FileSystemListener.ROOT_ADDED) {
              /* SD Card is available. */
          } else if (state == FileSystemListener.ROOT_REMOVED) {
              /* SD Card is not available. */
          }
      }
  }
  

  I was not able to find a corresponding WebWorks API or API community well, so I think you need to create your own custom extension to implement this feature of the listener.

• Event when the application closes

  Hi *.

  is there an event when the PlayBook application is about to close? I would like to save at this time where the configuration etc.

  Not that I know of.  It will be an event at the level of the AIR that is triggered when this problem occurs, and I do not think that such an event is currently on the Tablet OS.
