• 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.

  Original title: anyone know what this means? Its a new one on me!

  Anyone know what this means?

  The event of COM + a system attempted to RAISE the event object: change subscription events but had received a bad return code.    HRESULT was 80040201.

• Define and raise custom events

  I am designing and building a library of reusable Cast that can be included in a variety of other Director projects. This library will provide an interface to joint Code readers barcode that appear as a keyboard on the computer and also provides interfaces for interacting with external software.
  
  My problem is finding how to set and trigger custom of this Cast library events. Currently I set him up in a Global Script within the library. However, all it seems I can do the script is call a predefined function that implemented the film container. He can't really have several event listeners.
  
  There are two events that I am trying to define and raise:
  1. the notification when a label barcode is scanned
  2. the notification when a server database search ends
  
  The typical application flow is that a film's Director parent will sit idle waiting for a TagScan event mode is triggered. After the TagScan event, a request is sent to a central server to retrieve the associated information in the barcode that has been analyzed. Because we don't want UI suspended pending data to return, there was an another event notification when data are available for use.
  
  So my question is really in two parts:
  1. is my approach to the use of a global script in an external library to Cast the best way to put in place a reusable module?
  2. is there a way to define and trigger custom since a global script events?
  
  Thanks in advance,
  Shawn.

  1. the best way to create reusable code is to use behaviors and parent scripts. Some 98% of your code should be one of these two types - not movie scripts.

  2. by "global script" I assume you mean a set of functions in a movie script. If so, then it is not a good approach.

  Here is the skeleton of how I would approach. A system of events at its basic level is nothing more reminders with an object that queries the status set up other objects. A reminder is when an object passes a reference on behalf of one of its names of Manager to another object. This allows the second object to make a call to the first object. When he made that call, belongs to the second object.

  What you need is an object that monitors stocks asynchronous data recovery and drive barcode from the server. Create a Parent script with the following code.

  -Barcode monitor

  property pEvents - list of events and the saved objects that is called when an event occurs.
  property pTimeOb - timeout object used for the periodic polling/verification of the status of various asynchronous actions.

  the new me
  pEvents = [#BarcodeScanned: [], #DataReady: []]
  pTimeOb = timeout () .new ("BarcodeMonitor", 200, #CheckAsyncStatus, me)-means "200" we check five times per second.
  return to me
  new end

  on addEventListener, CallbackObject, CallbackHandler, event - script instance, symbol, symbol
  -can add validation of argument here.

  CallBackInfo = [#CallbackObject:CallbackObject, #CallbackHandler:CallbackHandler]
  pEvents [Event] .add (CallBackInfo)
  end addEventListener

  on me, removeEventListener CallbackObject, CallbackHandler, event - script instance, symbol, symbol
  -code that walks the list and deletes all corresponding combinations object and handler for the specified event.
  end removeEventListener

  on CheckAsyncStatus me, Timeob
  -check the status of various asynchronous barcode things happening.

  -Callback sample
  -At this point, some data is ready and has been recovered
  Data = "everything data".
  EventCallBacks = pEvents.DataReady
  Repeat with CallBackInfo in EventCallBacks
  call (CallBackInfo.CallbackHandler, CallBackInfo.CallbackObject, data)
  end repeat
  end CheckAsyncStatus
  ----------------------------------------------------------------------

  The above code sets up a mechanism for registering callbacks with the subject "bar code monitor" and uses a timeout object to periodically check the State of the asynchronous actions.

  Now any object who wishes to be notified of an event fits simply by using the addEventListener method. Or let's say that we want our object of global struggle to listen to the returned data. The next Parent script would be created things.

  -control

  global gBarCodeMonitor

  the new me
  gBarCodeMonitor.addEventListener (I, #processData, #DataReady)
  return to me
  new end

  processData me, given
  -do something with the data
  end processData
  -------------------------------------------------------------------------

  You then create your objects in preparemovie.

  global gBarCodeMonitor
  global gControl

  on prepareMovie
  -installation Global Singletons

  If gBarCodeMonitor.voidP then
  gBarCodeMonitor = script ("Monitor Bar Code") .new)
  end if

  If gControl.voidP then
  gControl = script("Control").new)
  end if
  end prepareMovie
  ---------------------------------------------------------------------

  With this configuration, you can have several objects to register for an event and a unique object with several events.

  If you are not familiar with the scripts of Parent. So take the time to learn. The programming of your life will become much easier the day you're going to OOP.

  I have not test the code, so there may be a typo or something. But the basic idea is there.

• LabVIEW digital control does not raise an event changed value when the button entry is hit

  I used to be able to type a value in a numeric control of LabVIEW, then press 'Enter' to trigger an event "changed value".  Then at some point, this no longer works.  I have to click elsewhere to trigger the event of value has changed.  The up and down arrow keys work always, but just typing a number then press enter does not work.  Is this a configuration settings got accidentally changed?  Help, please!

  
  

• 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.

• 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).

• How to raise an event (in the structure of the event) comparison function output

  Hello

  I want to triger specific event from a structure of event with the release of the comparison function. I tried several times but the output of the comparison function is not triggered. Please, propose solutions.

  Kind regards

  Mlad

  If you want to use a structure of the event, you must react on the digital inputs, for example as follows:

  

  Notice that the VI is inactive unless a change control (x, y, stop), date on which Boolean values are updated, comparison made, his played if necessary, and VI stopped if you press stop.

• How to I raise an event based on the State of a button?

  I'm trying to trigger an event based on the State ON / OFF button.  When I click on the button, I want the structure of the event in a loop to trigger each iteration until the button goes back to the OFF position, manually or programmatically.  Is there an easy way to do this?

  Thank you very much.

  A structure of the event is absolutely necessary?  It's so simple with just a case structure, as shown in figure 1.  If you use a structure of the event, you can place the structure dealing with the push button inside the time-out event, as shown in Figure 2.

  

• How do I know which control raised the event?

  In my program, there are six buttons that do similar things, such as changing the value of a table according to which the button is clicked. I used an event structure to do this. However, rather than repeat my codes six times in six events (one for each click of a button), I would like a case of event that meets at one of the six program buttons. The question is, how do I know which button is clicked on the inside of the box (of the key can be either false or true, then the value of the play button won't help)?

  Configure the node event property to return the ref of the object that triggered the event. The referee can be used to check if she even control using various methods (name, equal to a Ref etc.).

• Get the name of the object raising the event

  If I have a change event for a checkbox that is declared like this:

  topmostSubform.Page2.Competitions_CB.Checkbox::change - (JavaScript, client)

  How can I get the path of the object in a variable to process and extract the part "Competitions_CB"? Same route to the top of the tree of objects would be nice, but I can't seem to find the property that returns the object names.

  I went through all properties that seemed likely, xfa.event, events and this, but nothing seems to be what I'm after.

  Hello

  With the help of 'this.somExpression' will return a string of the trajectory of the entire article;

  XFA [0] form [0] .topmostSubform [0]. Page 2 [0]. Competitions_CB [0]. Box [0]

  You can also use 'xfa.context.somExpression' to return to the same thing, using xfa.context is very convenient when the code is in a script object and called many events of the object.

  In addition, "parent.name" would return the "Competitions_CB" part, so parent.somExpression would return

  XFA [0] form [0] .topmostSubform [0]. Page 2 [0]. Competitions_CB [0]

• 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);
            }
  }
  

• Remove several children and raise an event if no child more?

  I use for loop to display 3lifes on stage to help:

  /////////////////////////////////////////////////////

  for (var i = 0; i < 3; i ++) {}

  var: life life = new life();

  Life.x = 100 * i + 650;

  Life.y = 20;

  addChild (Life);

  }

  ///////////////////////////////////////////////////

  and I have already create a hitTestObject on the character when the character comes in contact with a movieclip, removeChild (Life);  is triggered. The first child deleted successfully, but when it comes to the second, an error pops up:

  ArgumentError: Error #2025: the supplied DisplayObject must be a child of the caller.

  at flash.display::DisplayObjectContainer/removeChild()

  at _4_fla::MainTimeline/hitBoy() [_4_fla. MainTimeline::frame1:52]

  at _4_fla::MainTimeline/dropEnemy() [_4_fla. MainTimeline::frame1:41]

  What should I do to fix this? and how to trigger an event after that no more life is left?

  1. Why do you not use import flash.events.Event;?

  You wanted to send an event... So I sent the new Event(); If you use class come, you must import it, otherwise, you get a compilation error.

  2. your Solution actually works, he removes my mistake and dead second and third without are the tips is to make individual addchild in an array?

  The idea is to store references to your life in a table, so you can target as many lives as you wish. You have used only a single variable - life, which can only point to a single object.

  3. I try to run:

  removeLife();

    removeLife();

    removeLife();

  for the third time, butYou have no more lives. doesn't seem to triggered in the output window?

  Do you have addEventListener ("dropDead"...)? Use the method trace to print from lives.length:

  4. when I run removeLife() for the fourth time, an error occurs?

  TypeError: Error #2007: child parameter must be non-null.

  Sorry, did not bulletproof. You should stop the game when you have 0 lives anyway, so this shouldn't happen. But try this instead:

  // this function triggers when I'm supposed to lose life
  function removeLife():void {
      if(lives.length == 0) {
          trace("What are you doing here? You should be dead already!");
          return;
      }
  
      var Life:life = lives.pop() as life;
      removeChild(Life);
  
      trace("You have still " + lives.length + " lives.");
      if(lives.length == 0) {
          trace("Baam! You're dead. Dispatching event.. 'hope somebody is listening.");
          dispatchEvent(new Event("dropDead"));
      }
  }
  

• 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.
