CompactRIO with dynamic event

• Events unregistering on a cluster without Unregistering for all dynamic events

  Hello everyone

  I've been playing with dynamic event record but I hit a problem.

  Normally if I want to stop triggering events on a single control I will be wire constant ref with the correct type in the registry for block of events. This means that I don't have to use the unregister for events block and then rebuild the entire events list to registry when I only want to stop the events on a control.

  However, if I try to bring together a group of the refs (which cannot necessarily be of the same type) in a cluster then I can no longer cancel the events on this cluster registration from the register of events work a group of control constants.

  An alternative would be to use an array instead of a cluster, but this has two disadvantages: it does not create a case of dynamic event for each Member of the array and all controls must be the same type or they are co-erced to a more generic control class.

  I've attached an example VI (labVIEW 2011 SP1)

  I think I finally get the problem now.

  You need feed two references in separately.  You can cluster the registry OUT for events, I know, but I don't think that what you want will work.  You know that you can enter the tables in a table instead of a cluster, right?

  Shane.

  PS to be clearer.

  Register to activate your button separately from the rest.  Save all your "to be marketed" references - individually, not clustered - in a second 'register to events' and then together the two outputs (with the Save refnums event) before passing into the structure of the event.  You might have what you want.  So big cluster AFTER signing up, not before.

• With the help of registration of dynamic events for a Subvi

  Greetings to the forum LV,

  I'm having a problem with the inclusion of dynamic events in a Subvi and hope someone here can help you! Attached, is the culmination of many attempts to try to understand the inclusion of dynamic events. Basically what I'm trying to do with the screw joint is 1.) have a button that controls output PWM, 2). a speed selection menu that can enter 1 button said.) with an array of pwm values predefined; and finally, 3) to have some sort of event program which "connects" controls in 1). (and 2.) (IE, if I move the button to an exact value shown in the table, the speed selection must match this event). So far, I can say with certainty that the "speed selection" event card will not work because "New value" & "Old value" refer now to the refnum and not the selection of speed control (I intend to solve this problem after I solved this problem of the Subvi). However, the map of event engine speed PWM should work (when matches button among the values in the table, the selected speed will also report the "speed selection" control), which allowed me to reach my conclusion that the Subvi is not working.

  My reference to dynamic Subvi Event Registration: http://digital.ni.com/public.nsf/allkb/A882E27D1D7A949386256E0D0066B91A

  You need to make a different State for 'Timeout' in the Subvi and also avoid passing the value of timeout as -1.

  Find the file code.

• It is back to LV2012 that the terminals of dynamic events are displayed by default?

  Between writing the title of this question and the drafting of this body, I realized my 'mistake' - which is between a function and a bug:

  If you drop a handler Structure in a given range from space empty diagram, the structure fell with the Terminal of dynamic events hidden.

  -but...

  If you drop a Structure of event handler in a range of context by right-clicking a user event Ref or event recording Refnum, the structure fell with this shown Terminal!

  Neat!

  To be more precise: the Structure of the event appears twice in the palettes.  One of the subpalette of Structures did not have terminal visible dynamic event, made one in the case of subpalette (which you can get by clicking right strategically).

• the exact position of the mouse click xy graph while he plotted graph with mouse events

  Hello

  IAM using Graph xy for multi locations

  IAM traced graphic with mouse movement and events using the example attached (draw the graph with mouse events)

  but in sub vi Values.vi scale there are two constants 66 and 30 when I change my plot (I also change the scales), then the mouse position and chart position (cursor) value are not well aligned, but when I change the constants mentioned above I get the alignment perfect between the cursor and the last point in the path.

  as I went to another parcel (with scalability again) the same alignment problem resurfaced.

  I need to replace these two constants with something dynamic

  solution to my problem is

• Static vs dynamic events - dynamic events are empty

  During the implementation of my project, I used static events to manage the interface. The Structures of the event separated while loops in the same vi.

  I changed the architecture to make code modular and I use dynamic events. Dynamic events are captured in separate subVIs event Structures. I spend the references to the controls in the subVIs that have Structures of the event and I record the events of the references.

  Static events had no problem.

  With the dynamic events, I see that some events are not consumed. Instead, I see the event inspector window a few times an event is 'empty '. This means that the button should be pressed again.

  I am attaching two examples of projects that have exactly the same functionality.

  The testDemo2 uses dynamic events.

  The testDemo4 uses static events.

  How much detail I miss the dynamic architecture events leading to lose some events?

  This UI code is crizazy. It is difficult to really say what is happening, but you have a Unregister for events VI after the structure of your event to during each single loop and then re-register at the beginning of each loop. Empty all dynamic events currently in the queue and then re-registered again.

  You must only register events, only once and cancel the registration at the end of the application.

  What you do isn't really very modular. Even if you add a new event/control, you still he wire through the Subvi references and register, so you're not really save any time. There is nothing wrong with having a static event for your UI record. What you want probably is an architecture of messages in queue manager, where your static user interface events create messages that are sent to a loop of consumer to manage.

• Lack of dynamic event (declaring)

  In my application, I have one notifying registered as an event 'user '. There are three structures of the event, each in a while loop; in every structure of the event, the event Notifier is recorded as "dynamic event. In both structures, the delay is set to '-1' (infinite). In the third stcructure, the time is set to 5 ms; the case of timeout takes 500ms to complete (for example, by using 'Wait ms'). A structure of additional event triggers this event notifier.

  What is happening is that the two structures with infinite time-out catch this event (I think), but lack the structure with a short timeout and expiration time of long-running cases. If I do the waiting time is long and the case timeout run quickly, this structure has also intercepts the event. It seems that when executing the timeout case, the event is canceled.

  An example VI is attached.

  Is this a bug or I do something wrong?

  Thank you

  Sergey Liberman

  You're doing it wrong.  You create entries in separate events for each loop.  You're really lucky that the two loops are both able to see the event and run.  Once a loop handles an event, it get cleared out of the queue of the event.  The two structures meet at the same time, but once that one or the other ends, he is allowed out of the queue and the 3rd structure ever sees.

  This has come up before.  This recent thread discussed.

• Add more dynamic events registration refnum

  Hello

  I have a wire that passes Event Registration refnum to my structure of the event. This thread is from VI, that I don't want to touch. He spent recording for the cluster of user events.

  I would add more dynamic events to the refnum (but not to the cluster), so I would like to re-record with the addition of new events.

  When I'm passing this refnum to block 'Register for events', LabVIEW does not allow me to expand this block and add new events, which I think is understandable.

  How can I add more dynamic events to the refnum?

  Close, but no cigar.  When you add user events, you want to be sure that every event has a unique name, then name your constants defining the events differently (as shown here).

• Need help with dynamic Action through 4 items

  Hello everyone.

  I'm having some trouble trying to comp with dynamic action that will turn on or display a select list item when a value is set for the four elements of the Radio button group.

  P1_SELCT_LIST

  P1_RADIO_GROUP_1

  P1_RADIO_GROUP_2

  P1_RADIO_GROUP_3

  P1_RADIO_GROUP_4

  So once all four Radio groups are not null, I want the select View list item.

  Any help with this would be great.

  I'm on Apex 4.2.0.00.27

  Hello

  You can create the following action:

  Event: click on

  Selection type: jQuery selector

  jQuery selector: radio

  condition:

  $v ('P1_RADIO_GROUP_1')! == ''

  &&

  $v ('P1_RADIO_GROUP_2')! == ''

  &&

  $v ('P1_RADIO_GROUP_3')! == ''

  &&

  $v ('P1_RADIO_GROUP_4')! == ''

  Then add a real Action as follows:

  ACtion: show

  Fires when the result of the event is: true

  Fire on the page loading: No. (uncheck)

  Assigned to elements, selection type: product (s)

  Product (s): P1_SELECT

  Also add an Action to false as follows:

  ACtion: hide

  Fires when the result of the event is: false

  Fire on the page loading: YES (check)

  Assigned to elements, selection type: product (s)

  Product (s): P1_SELECT

• Help with dynamic action and the selection list item

  G ' Day Apex gurus.
  
  I have problems trying to achieve to trigger the Help window from an element automatically select. A Help window is triggered when it is clicked on the label of an item, but my customer wants to be triguered automatically as soon as the user clicks to view the options in the select list.
  
  I think I should be able to do with dynamic actions but I can't function.
  
  I know when someone clicks on the label of the item selection list trigger this JavaScript
  
  JavaScript:popupFieldHelp('277938589795252851','1545903379570909')
  
  So I want to trigger the javascript also when the user click on the item selection list and pull down the options and for that I think that the dynamic action is the way to go, but I can't do things.
  
  That's what I have to do:
  
  I created a dynamic option as follows:
  
  Name: test
  Sequence: 30
  Even: click
  Selection type: product (s)
  Article (s): P1_RATING <-a selection list item
  Condtion: - no requirement.
  
  Real Actions
  Sequence: 10
  Action: Run the JavaScript Code
  Fires when the result of the event is: true
  Fire on loading the page: checked
  Code: javascript:popupFieldHelp('277938589795252851','1545903379570909')
  
  Thank you anyone who can tell me what I'm doing wrong here or bring a solution to my problem to trigger the Help window from an element automatically select.
  
  Kind regards
  Carlos

  Hi Carlos,

  I've set up a test case of exactly in the same way and it worked fine for me. I've created a page element called P1_DA_DEMO and added some values of the static selection list, then added a help text. I used the settings are lower, I suggest you try again, but also make sure that you have no other Javascript errors on the page. Use a tool like firebug to check.

  Name: Action Dynamics demo
  Sequence: 10
  Even: click
  Selection type: product (s)
  Product (s): P1_DA_DEMO<- a="" selection="" list="">
  Condtion: - no requirement.

  Real Actions
  Sequence: 10
  Action: Run the JavaScript Code
  Fires when the result of the event is: true
  Fire on loading the page: unchecked
  Code: javascript:popupFieldHelp('277938589795252851','1545903379570909')

  Scope of the event set a Bind s.

  Thank you

• Repeater and dynamic events

  I use a Panel as my Repeater class. I have one by using a class that triggers dynamic events in this Panel. In the Panel, I have listeners at these events.

  I see that the class dispatches the event, but the Committee did not receive it. What can be wrong?

  It is a class code:

  var dynEvent:DynamicEvent = new DynamicEvent ("onConnect", true);

  dispatchEvent (dynEvent);

  and it comes to the Committee

  addEventListener ("onConnect", onConnect);

  private void onConnect(event:DynamicEvent):void

  {

  trace ("nothing is here");

  }

  Thank you

  Hi Zolotoj,

  Try to register the eventListener with the Socket class reference... in your comp in Repeater.

  So use socket. addEventListener ("onConnect", onConnect);

  If your other events are also shipped in the socket class register all eventListeners w.r.t. instance of the socket class as I did above...

  Repeater

  private var socket: modulecode. Socket is new modulecode. Socket();

  public function set data(sewingMachineData:XML):void

  {

  addEventListener ("our", our);

  addEventListener ("onSecurityError", onSecurityError);

  addEventListener ("onClose", onClose);

  addEventListener ("onError", onError);

  Socket. addEventListener ("onConnect", onConnect);

  socket.reConnectSocket ();

  }

  private void onConnect(event:DynamicEvent):void

  {

  He is not here

  Green.Visible = true;

  Red.Visible = false;

  }

  Thank you

• Problem with dynamically created in a loop function

  Hi, the project is to create a thumbnail image dynamically from a xml file and display an overview with the event delivery. My problem is that I dynamically create a delivery for each thumbnail and inside the function the name of the image to load. I get no error, but the loaded image is always the last of the loop. Where is my mistake? Is there a solution?
  Any help will be welcome. I work hard on it but not more idea. Thank you very much for you reply

  Thank you very much Pajaroplus, it works with your help!

• Deploy file. DLL for CompactRIO with LabView

  Hello

  I have compiled a DLL-file of SimulationX, and I want to deploy this file on a CompactRIO with LabView. How do I do that?

  Thanks in advance

  A correction, the x 900 cRIO and 908 x seem to use an x 86 CPU and execution Pharlap ETS. PharLap ETS allows you to run SOME Windows but by far not all DLLs, because it supports only a subset of the Windows API available on Windows 2000. So, if you have a controller of 908 x cRIO (900 x are very old and unlikely to be used these days) you MAY be able to deploy the DLLS on your cRIO system. To make sure that you check the DLL API not supported importation by the auditor of the DLL which can be downloaded for your version of LabVIEW specific here.

• registration of dynamic events - FP not in memory?

  Hello

  I have the problem that I do not understand the event registration Dynamics trhw.

  In my application, I have multiple threads that are initialized when the application starts and I switch between them using secondary.

  In one of this module, I want to register some dynamic event to find whitch controll cluster has been pressed.

  Why do I get error 1001?

  I have a static reference for all modules in the main thread. I start modules, but I don't open their FP.

  

  Well, your image is confusing because you cannot run without wiring this reference.  But if you did that then the error comes from the fact that your VI does not have a front that is open when you sign up for it.  So that the control reference isn't really exists.  I mean there are but you cannot reference a control that has not been opened.

  I think that what you want to do is open the front panel, and then set it to hidden.  Then after that the front panel has been open and hidden, to join the control event.

• How can I access the data associated with an event within the event handler function?

  Hello

  In my LabWindows code, I try to use a DLL that has been developed in .NET (c#).  I used the built-in labwindows Wizard that converts the DLL to a usable 'instrument'.  Almost everything seems to work, except that I have 1 problem.

  There is an event (defined in the DLL) that I am able to detect.  I know that the reminder of the event is called at the right time.  But the problem is that in this function, I can't access the data that is supposed to be attached to the event.  It worked fine in c#, but I don't know how to do in LabWindows.  Here's what looked like in c# event handler function:

  void AppLoaderEventCallback (CommonLib.CommandResult MyResults)

  {

  MyResults is used in the body of this function

  }

  But in LabWindows, I can't seem to access the MyResults data structure.  Here's what I do:

  public static int CVICALLBACK AppLoaderEventCallback (CommonLib_CommandResult MyResults)

  {

  I can't access MyResults here

  }

  Can you help me with this?  I'm doing something wrong?

  Thank you very much for your help.

  -Mike

  I think that your statement of callback function is perhaps not quite correct. Look using the parameter "callback function" function Panel of the generated __Create function associated with this event. This shows the declaration of the callback function - make sure that your callback function is declared in the same way.
