DAQmxRegisterEveryNSamplesEvent, still called inside the callback

Hello

I wonder if after using DAQmxRegisterEveryNSamplesEvent to give me a call N samples, I can call back the same function or another without having to restart the task to change the number of samples before receiving a new reminder.

Thank you

Alex

Dear laurman

It is recommended not to have only one thread per task. You put your DAQmxRegisterEveryNSamplesEvent in the same thread as your task and reminder of the function. The DAQmx driver is designed for the task, the events and the reminder all in the same thread. If you have it in a separate your callback thread won't be able to see this event and be triggered because it is not in the same thread as the task.  In short, once you call this to your task, you can not set again without restarting the task.

  • Error #1009 when sound inside game, a movie clip that is called to the scene with child add method

    What is supposed to happen

    I have a clip that is called when the user clicks a button. When moving clip appears music is expected to play. When the user clicks the close button the music stops and the clip is removed from the scene.

    But then I get an error

    When I test the movie I get the following error:

    TypeError: Error #1009: cannot access a property or method of a null object reference.

    to mc_playSong / frame2 () [mc_playSong::frame2:6]

    This is the code that calls the clip on the stage (no problem here):

    Call the video clip with the song played on stage

    stage.addEventListener (MouseEvent.MOUSE_DOWN, goButtons);

    function goButtons(event:MouseEvent):void

    {

    If (event.target is song_bnt)

    {

    SoundMixer.stopAll ();

    addChild (myPlaySong);

    myPlaySong.x = 558;

    myPlaySong.y = 384;

    Event.stopImmediatePropagation;

    }

    The following code inside the clip is called to the scene. The music is meant to play:

    Stop();

    Variables for listening to music

    var RJPlaySong:RJSong = new RJSong();

    var RJPlaySongChannel:SoundChannel;

    Music for plays

    stage.addEventListener (Event.ENTER_FRAME, startRJSong); (I think that the error in the code is in this function. When I comment on him I don't get error.)

    function startRJSong(event:Event):void

    {

    RJPlaySongChannel = RJPlaySong.play ();

    }

    Stop all sounds, sets variables to null and calls a send event that removes the clip of the scene.

    bnt_closeSong.addEventListener (MouseEvent.MOUSE_DOWN, closeCreditSongScreen);

    function closeCreditSongScreen(event:MouseEvent):void

    {

    SoundMixer.stopAll ();

    RJPlaySong = null;

    RJPlaySongChannel = null;

    dispatchEvent (new Event ("RemoveMCsong"));

    }

    Someone at - it ideas? This seems to be a pretty simple question, but I can't understand it.

    I meant that you have quoted just to be taken literally.  If it's still not clear what I say or what did your code, try the following in order to demonstrate the IT change... This code to be...

    stage.addEventListener (Event.ENTER_FRAME, startRJSong);

    function startRJSong(event:Event):void {}

    trace ("I can do this all day");

    }

    After doing this, you can see why you want to only call the function once, and you could eliminate most of it and just put...

    RJPlaySongChannel = RJPlaySong.play ();

    Instead, or as I said originally, you can change it to be...

    function startRJSong (): void

    {

    RJPlaySongChannel = RJPlaySong.play ();

    }

    startRJSong();

  • How to run the callback model SequenceFilePostStepFailure after step fails with the calls of the nested sequence

    Hello

    I want to appear a message immediately box on any test failure.  I thought I could use the reminder of the SequenceFilePostStepFailure model to achieve this, but when I change the reminder of process model to achieve this, I found that the recall code is executed only for the failures of step of the top level of the page sequence file.

    My test code has sequence called before mutiple files to the granularity of the basic numerical limit test that range from success or failure, so I would like to run the callback SequenceFilePostStepFailure immediately at this level.  I can accomplish this by adding a substitution of recall of SequenceFilePostStepFailure in the file of the sequence in question, but I prefer to use the implementation of reminder default template, so I can't find all the places where numerical limits tests are executed and cause the ASE of pass/fail.

    I have attached a few sequences of the example I want to illustrate the problem.

    Thanks for the help,

    Daniel

    My fault, I see now that the recall of model should I have changed is the ProcessModelPostStepFailure.  Problem solved.

  • Asynchronous call still slow down the main VI

    Hello!

    I currently have a 'main VI' quick process underway, and I have a Subvi, which is essentially a device data collection. However, this Subvi works at 1 Hz, while my main VI runs a lot faster.

    I created an asynchronous call to the Subvi and set it such that the hand is not expected to incoming data. I followed these very simple instructions: http://zone.ni.com/reference/en-XX/help/371361L-01/lvhowto/acbr_call_and_forget/

    However, when I run the present, my main VI is as slow as if I did not use an asynchronous call. For your information, the only node inside my main while loop is the node "Start Asynchronous Call.

    Is there something I'm missing about how works this Subvi without slowing down my main VI?

    Thank you very much!

    I guess that your main problem is that the DLL calls are set to run in the user interface thread.  This could prevent your main VI to update until the end of this call to the DLL.  Try to set their 'Run in any thread.

    In addition, there is no need keep saying this VI to run over and over again.  He needs is called only once.

    Strange question to ask.

    Yes. This is the standard behavior in most (if not all) procedural and object oriented languages.

    A procedure, function or a method is a unit of code.

    You can call one of the other units. Units can call themselves (recursion). Technically, this means simply by pushing the battery current (to save the stack of the current device memory), the call to the new unit and then popping up battery when control is returned to the unity of the appellant.

    There are very few exceptions to this. The only one that comes to mind programming languages I've used through the years, is natural 1 - could not call a new unit of code to replace the existing one in memory. If no call-and-return was possible.

    Exactly what did you ask this question? Some newcomers to confused Oracle SQL and PL/SQL - two different languages aside server. And then also mistaken for PL/SQL client command vocabulary of SQL * more.

    You will need to make sure that understand the basics of programming (applies to most current programming languages) and Oracle concepts.

  • Inside the af AF:commandLink: Iterator not calls actionListener method

    Hi all

    I use Oracle Jdeveloper 11.1.1.7.1.

    I have an ArrayList which I am an iteration in the jsff using af: iterator and display the value in a command link.

    Now, when I click on the order link, the action listener is not called instead the get method of the value of the iterator is called.


    Here is my code jsff:


    " < trh:tableLayout xmlns =" http://MyFaces.Apache.org/Trinidad/HTML "

    ID = 'tl1' >

    < af:iterator id = "i1" var = "var" lines = "10".

    value = "#{backingBeanScope.PortalBean.orderSearchResults}" >

    " < trh:rowLayout xmlns =" http://MyFaces.Apache.org/Trinidad/HTML "

    ID = "rl1" >

    " < trh:cellFormat xmlns =" http://MyFaces.Apache.org/Trinidad/HTML "

    ID = "cf1" >

    < af:panelGroupLayout id = "pgl14" layout = "horizontal" >

    < af:commandLink text = "#{node.orderId}" id = "cl3" "

    actionListener = "#{backingBeanScope.PortalBean.highlightNode} '"

    partialSubmit = "true" / >

    < / af:commandLink >

    < af:spacer width = "10" height = "10" id = "s2" / >

    < / af:panelGroupLayout >

    < / trh:cellFormat >

    < / trh:rowLayout >

    < / af:iterator >

    < / trh:tableLayout >

    Now, whenever I click on the order link, instead of calling the method highlightNode of the bean, it called the getOrderSearchResults() of the portal bean.

    I tried to change that to a button, but no luck, and the worst is that it does not give an error or any exception.

    Someone can suggest, what is the problem here, how can I invoke the listener in action during the click on link getOrderSearchResults() instead.

    Hi user

  • leak memory with the callback function

    Hello

    I'm pretty new on LabWindows and library ninety, I worked mainly with LabVIEW.

    I am trying to create a basic c++ client (no GUI) that sets up subscriptions to several network publication of a PXI DAQ data variables.

    The data for each variable is sent in a cluster and contains different types of data with a 2D array large int16 for the acquired data (average size of array is 100 k in total, and the average time between the data being sent is 10ms). I have an average of 10 of these variables DAQ.

    I'm passing the same callback function as an argument to all of these subscriptions (CNVCreateSubcription).

    He reads all the correct data, but I have a problem is that I have a memory leak in the callback function in the CNVCreateSubscription.

    I have reduced the line of code one and found the function that actually causes the memory leak, it's a CNVGetStructFields(). At this point in the program data has not yet been adopted for the variables of the customers.

    It is a simplified version of the callback function, where I just unzip the cluster and get data (showing only a field in the cluster in the example, showing also doesn't not the decleration).

    The function is passed in the function to subscribe, as follows:

    public static void CNVCALLBACK SubscriberCallback(void * handle, CNVData data, void * callbackData);

    CNVCreateSubscriber (url.c_str (), SubscriberCallback, NULL, 0, CNVWaitForever, 0, & Subscriber);

    public static void CNVCALLBACK SubscriberCallback(void * handle, CNVData data, void * callbackData)
    {

    int16_t daqValue [100000];

    unsigned long int nDims;
    unsigned long int daqDims [2];
    CNVData fields [1];
    Type CNVDataType;
    unsigned short int numFields;

    CNVGetDataType (data, & type, &nDims);)
    CNVGetNumberOfStructFields (data, & numFields);
    CNVGetStructFields (data, fields, numFields); //<-------HERE is="" the="" problem,="" i="" can="" comment="" out="" the="" code="" after="" this="" point="" and="" it="" still="" causes="" a="" memory="">

    CNVGetDataType (fields [0], & type, &nDims);)

    CNVGetArrayDataDimensions (fields [0], nDims, acqDims);
    CNVGetArrayDataValue (fields [0], type, daqValue, daqDims [0] * daqDims [1]);

    CNVDisposeData (data);

    The average settings, I use all my memory systems (4 GB) in time.

    My question is, all else have experienced this and what might be the problem/solution to this?

    Thank you.

    I see that you disable only handle memory (data), but not the memory of the structure; Therefore, before calling CNVDispose (data) you should have something like

    While (numFields > 0)
    CNVDisposeData (fields [-numFields]);

  • App.Open does not so called inside onclick()

    Hello

    Since you are using a modal dialog box, it is likely that InDesign cannot open a document, or do anything until you close the dialog box. Your solution is to use a modeless dialog box (i.e. "the palette") or to close the dialog box before you open the document.

  • How to center the characters inside the cells of the comb field (text field)?

    Hello gurus,

    [Intro]

    I'm working on the preparation of the legal form of the income tax.  Due to the structure of the sophisticated form and the request of the client to prepare for the return of enormous size (more), I decided to redo the obsolete form using option "comb of" in order to reduce the size of the source and prevent problems with memory allocation on the client side.

    [Issue details]

    Legal obligation is to have the Courier New 16pt 18pt police and cells of the size of some.

    This is how the form provided by the tax authorities looks like:

    adobe1.png

    Here you can see that the characters are somehow centred inside the cells, but when I create the comb in my livecycle designer, it is not the case and I have another layout:

    adobe2.png

    Look at how the letters are placed inside the cells. After some research I discovered that there is a left margin that still exists in every cell of the comb, probably triggered by the border. Tried to edit the XML source but has not reached a significant success. The issue is not caused by the narrowness of the cells and but even with the very broad.

    Here's my current XML:

              <field h="5.7mm" name="STR_230_TOT_TX" w="60mm" x="4.264278in" y="4.458417in" anchorType="middleCenter">
                   <ui>
                      <textEdit hScrollPolicy="off">
                         <border hand="right">
                            <edge stroke="dotted"/>
                            <corner stroke="dotted" thickness="0.176mm"/>
                         </border>
                         <margin bottomInset="0mm" leftInset="0mm" rightInset="0mm" topInset="0mm"/>
                         <para hAlign="left" vAlign="top"/>
                         <comb numberOfCells="15"/>
                      </textEdit>
                   </ui>
                   <font size="16pt" typeface="Courier New"/>
                   <margin bottomInset="0mm" leftInset="0mm" rightInset="0mm" topInset="0mm"/>
                   <bind match="dataRef" ref="N140_TAX_AMOUNT"/>
                   <assist>
                      <speak disable="1"/>
                   </assist>
                </field>
    

    That's how comb field is supposed to be rendered (screenshot of documentation):

    adobe3.png

    Everything is centered and it's supposed to behavior to see.

    Are there possible solutions how to put tanks in the center of the cell?

    Hi Igor,.

    It's the police that you use that is causing the problem.

    I found it weird, your problem, so I did quickly a form with a text field with a comb.  I have not had the problem.

    So I took your snippet and added to my shape, so I have the same problem.  You use the new Courier, a policy that has the same width for all characters.  I don't know why the problem is as for me it should be in the Center as for all other fonts.  I would count this as a bug to support.

    I know that's not a solution for you, but this seems to be the root of the problem.  Maybe you can find another font, like Courier New, but has no width fixed.  I looked and it seems that there is a font called depicted, which uses the same letters, but is proportional.  The police is not downloadable for free, so I can't test for now.  Another page says this: "there is a proportional font that looks a bit like Courier. 'S called it American Typewriter. "Yet once again, I have not tested.

    • Depicted Serif is a proportional font by using Courier characters as a base.

  • Customcancel button doesn' reset the components of entrance inside the af: panelWindows

    We use adf Rich Popup of the elements inside the table update. The popup has an af:panelwindows inside. When the user clicks on the button inside each row in the table, the popup displays the details of that element, and user can update the information and close the pop-up window.
    or click Cancel and the popup will be closed without making any changes to the item.
    We decide to have our custom undo button to undo the insert and update.
    When clicking on the button cancel windows was closed, but when he opened the next time for another element inside the table the af:inputtext component has not updated / reset and
    for all other times, the data inside the inputtext component were still given to the first element. When you debug carefully I saw that the linked object is initialized and the value new object element
    but somehow this update server-side has not been reflected in the inputtext popup components. Point interesting is that outputtext were themselves refreshed and reset for the new value, the problem is only with the components of entry.
    (1) I've rechecked closing popup java scriped
    (2) I've put on so many closing is server-side and client-side
    (3) and of course I double checked that Im using right contentDelivery which must be set to "lazyUncached" when you want the popup read the binded value server side when his open ever.

    It worked again!
    Finally I read some documents on af:panelwindow and af:dialogbox.
    And I understand that although two this components can be used inside the pop-up window for the case to get the input data, af:panelwindow does not support custom Cancel button
    And by simply changing the panelwindow dialogbox, now all the compenentc of entry are reset to the value current binded to the side server.
    And don't forget that the cancel method should be called from server-side (listener client-side does not work!) with ActionListener bound to a method server that sends a java script to close the pop-up window.
    And don't forget no immediate command button should be set to 'true '.

    Is there another way to have customized cancel inside the af button: panelWindow?


    Thank you

      AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();
      List items = component.getChildren();
      for ( UIComponent item : items ) {
    
        resetValueInputItems(adfFacesContext,item);
    
        if ( item instanceof RichInputText ) {
          RichInputText input = (RichInputText)item;
          if ( !input.isDisabled() ) {
             input.resetValue() ;
             adfFacesContext.addPartialTarget(input);
          };
         } else if ( item instanceof RichInputDate ) {
          RichInputDate input = (RichInputDate)item;
          if ( !input.isDisabled() ) {
             input.resetValue() ;
             adfFacesContext.addPartialTarget(input);
          };
         }
       }

    You call this method with either the layout container that contains all your fields (in your case the popup or panelwindow.
