• change the frequency of the signal during execution

  Hi, I'm working on a VI to calculate excess of signal I think VI seems to be good (not sure) but now my problem is

  change the frequency during execution, which I am not able to do only when I stop and run the vi frequency changes... pls

  someone help me I tried to put in an event... but no use... maybe iam missing something pls help me...

  I noticed that you have some time a loop around the entire block diagram - I'm not entirely sure why that is.  The way you have your VI wrote that the two inner loops will never come out unless there is an error-'stop' buttons are hidden.  Thus, the outer loop is not do anything for you.

  Once you take it, it is easy to see why you cannot change frequency.  It is defined once, outside of the loops and so never gets checked again.  The best way to resolve this, in your case, is to use registers with shift on the upper loop and check if the value of the frequency has changed since the last iteration.  If so, generate a new waveform and feed DAQmx writing instead.

  See the version annexed to your main VI for what I mean.  (I also replaced the controls to stop with one that is visible and which will stop the two loops without your duty to hit the button abandon.) I'm also an error on the DAQmx read in the loop at the bottom, but I'm sure it will work fine on your equipment.

  See you soon,.

• Edit/delete/add scene coordinates in the table during execution

  Hello world

  I managed to build table allows you to store and record the coordinates of the stage and remind to control steps. However, I need change/remove/add details of scene during execution. I also need to allow the user to directly edit the coordinate from the scene of the array. Wondering what someone knows what is the best way to do it? Or is it better to use the matrix or Cluster? Thanks in advance.

  Best regards

  Thanks much altenbach for all the advice. I tried to do a table 2D control. I've been playing with table in the control. However, I still can't find out how can I detect that I change the data in the table 2D with the more recent issue during execution? How can I then update my current table with the latest data?

  Well, the 2D table is updated immediately and you do not all the other tables.

  Do you mean that you want to update XAbs, etc. where the just changed line is already selected?

  In any case, here's a simple project, perhaps it will give you some ideas. I would recommend using also the tables for XYZPos, entrances etc. and the XYZabs. This simplifies the code because you reduce the number of terminals and table operations.

  Let me know if something is not clear to you.

• (How) Can I change the priority for execution vi when running

  Hi all

  I use the demons (free running VI) and I communicate them through queues.

  They are part of my architecture of device driver and use a producer (of the Acquisition) architecture or Architecture consumer (for control)

  I have a single VI demon I deploy an 'object of device' using a class polymorphic implimentation.

  This implimentation has a deficit of subtle,

  I'm not able to change the priority for execution to the launch

  

  There is a property node taunts that it is possible, but the assistance (and run the error message) says not available during execution.

  Anyone know of another method?

  Here's what I thought about so far:

  1. do you have 5 different demons with different priorities [Distasteful for the maintenance of the Code]

  2. make low priority and ensure that at least 1 VI in the driver has a highest priority [do not know if it works, mask implimentation]

  Kind regards

  Tim L.

  You might think about putting a timed loop or timed sequence in your daemon and then passing a value of digital priority to your demon. This is the best solution I can think.

• Pass the value of the variable during execution

  Hello
  
  I have a package with a set of interfaces and three other variables.
  
  I want to pass the value of the variable at runtime, based on the value passed I want to decide which interface to run then. How can I do this? I got a set variable but I want to asssign the value during execution.
  
  Any help is greatly appreciated.
  
  
  Thank you
  San

  You have many options to achieve this goal.

  1. keep the run settings in the database, extract the Variables in a time of refreshment and use these variables in your Interfaces to get values of execution.

  2. change the value to the variables on the outside. You can declare a variable in a package as a step of the statement, and then use the variable in your interface in a successive step in your package. Then, create a scenario of your package and creating the scenario, it will prompt you to include the variables that you want to include as a startup parameter. Choose the one (s) concerned. Citing this scenario using Java or an OdiStartScen command or by using Webservices ODI externally, you can provide values of the runtime as a result.

  I hope this helps.

• definition of the background image of the file during execution

  So, I have another issue to resolve and my migration to 11.5 will be complete.  In the previous iteration, the project has been able to set the background image from an external file dynamically during execution.

  After the migration, it seems that the projector keeps the canonical path to the image of Member and looking for him there. In other words, loads of projector, but a file finder opens, saying: he cannot find the background image in the path of the source machine Director.  Setting the name of the file in the jargon does not stop this behavior doesn't happen.

  I tried to re - import the image as "link to external file" (which had the same results) and flat import (which does not load the file during execution, even if I put the file name in the jargon).

  Anyone know how I can do this, the value of the background image of a file during execution?

  Thanks in advance!

  I do it all the time.  Just make sure that the image is in the same location relative to the projector that's director file.  The easiest way is of course if the image is in the same folder as the .dir file, in which case, you'd sure as to put it in the same folder as the projector, and you can set the name of the file using:

  Member ("someExternalMember"). FileName = the moviePath & "filename.jpg"

  You can have it in subfolders as well if you want to make sure that the relative location is the same.

• Filter the Table during execution and keep uncommitted line changes

  Hello

  I have a requirement which has been quite difficult for me so far.

  I use the first version Jdev 12 c.

  I have a table of AF that is connected to a ViewObject that is used for sending new data.

  When I add lines to this ViewObject, I put a field that I intend to use for filtering so that the number of lines is not displayed at the same time.  This field comes from a selection of LOV.

  I want to be able to change lines are displayed in the table based on what is the current value of selection LOV.  This isn't a problem for me, and it works perfectly using a view criteria and a variable transitional EO I put in place.

  My problem is that when I select a new value in the LOV and change to bind the variable view criteria, I want all changes uncommitted to the lines to be preserved in the View object.  Currently, the lines are not keep their changes, and I need to do this, because after that the user has entered data for a large number of lines, there will be a commit to the database for all new lines added.  Is this possible or should I look for an alternative?

  I also tried to use a table filter in the link of the page layer, but I get an error that I can't debug. It is marked as Houston-34014.  In this method, I try to access my bean in pageFlowScope to filter the table.  This bean variable is updated when the LOV selection changes.  Error messages settings are {0 = oracle.jbo.Key [-220-225], 1 = root}.  I also read that this filter parameter is a static filter and does not dynamically during execution.

  Any help would be appreciated, thanks for reading.

• How can I change the elements of an Enum to execution?

  I have an enum that is full of items. I would like to change the labels on these elements using the runtime. When I try using the property node '[] strings' I get the following error:

  "Error 1073 in property node (arg 1).

  Possible reasons:

  LabVIEW: This property is writable only when the VI is in edit mode, or this method is available only when the VI is in edit mode.

  "Property name: [] channels."

  MGarry,

  something like this:

  

  Please note that this does not reset the contents of the table if you rerun the VI. You can add code to it.

• Change the elements of control Enum or ring gives weird dialogue

  Whenever I did a right click on a control Enum or ring on my FP and choose Edit items... I see the following image. It's almost as if I'm missing a dll or something that shows the info to change the Page Properties dialog box elements. Any ideas?

  

  Hey Ben,

  I use 8.6.1.  I ended up uninstalling LV altogether and put it back.  The question went, and all is well now.  I hope he doesn't because it would be a pain to have to reinstall every time LV.

  The repair, which I mentioned earlier has not fixed the problem.

• Adding series to the table during execution?

  Newbie :-)
  
  I'm trying to add series to a chart during execution because the number of series to draw is variable and only determined once the XML of a HTTPService returns...
  
  My chart looks like this:
  
  < mx:PlotChart id = "mainChart" showDataTips = "true" width = "100%" height = "100%" >
  < mx:series >
  ...
  
  If I add:
  
  < mx:PlotSeries xField = "Size" yField = "CompetitorPrice" displayName = "Competitor price" / >
  
  then the data plots OK, but try to create the same AS serial does not work (nothing appears):
  
  var newSeries:PlotSeries = new PlotSeries();
  newSeries.xField = "size";
  newSeries.yField = "CompetitorPrice";
  newSeries.displayName = "SeriesAddedAtRuntime!"
  mainChart.series.push (newSeries);
  
  Debugging presents the new series added and it seems OK... but it does not appear on the graph. No errors.
  
  I tried mainChart.executeBindings (); and mainChart.validateNow (); with no chance, but I guess as to what is to be the case here, as you can probably!
  
  What Miss me something to force an update of the chart with the new series added?
  
  Thanks in advance
  
  John

  It is not displayed because the table is not aware of the change in ownership of the series. I think that to run the following steps (give an or take a few syntax errors):

  var set = mainChart.series;
  var newSeries:PlotSeries = new PlotSeries();
  ...
  Series.push (newSeries);
  mainChart.series = series;

• Determine the size of the component during execution

  I am trying to build a component Paginagion of size fixed. The number of pages which means that the size of the paging is fixed, however depending on the content may vary. Most do not specify how much is displayed on a single page.

  The idea is to use the text as input and push as much as can be displayed on the page. Factors having an influence here is the fonts and formatting.

  To determine the page which you should see that I need to understand the amount of text that can be displayed. To do this, I need to know the size of the element that contains the text (think label). The size of the label is however only determined after that is layouted. So here's what I could do:

      @Override
      public void start(Stage primaryStage) {
          Label lbl = new Label("uitroweigudfgf jkfhgklfsjghslkghs kflgskjgh");
          System.out.println(lbl.getWidth()+","+lbl.getHeight());
          lbl.widthProperty().addListener(new ChangeListener<Number>(){
              @Override
              public void changed(ObservableValue<? extends Number> ov, Number t, Number t1) {
                  System.out.println(lbl.getWidth()+","+lbl.getHeight());
              }
          });
          lbl.heightProperty().addListener(new ChangeListener<Number>(){
              @Override
              public void changed(ObservableValue<? extends Number> ov, Number t, Number t1) {
                  System.out.println(lbl.getWidth()+","+lbl.getHeight());
              }
          });
          StackPane root = new StackPane();
          root.getChildren().add(lbl);
          
          Scene scene = new Scene(root, 300, 250);
          
          primaryStage.setTitle("Hello World!");
          primaryStage.setScene(scene);
          primaryStage.show();
     }
  

  After the third change, I have the dimensions of the label. With this method, I would have to push all of the text in labels to figure out what can be displayed.

  Is there a better way to do it?

  My basic problem was with the size of the labels. Try to find a solution I had a look at LabelSkinBase which uses the Utils class in the same package. This class provides methods (although private package) to calculate the size of the text that results from:

  static Text helper = new Text();
  
  static double computeTextWidth(Font font, String text, double wrappingWidth) {
    helper.setText(text);
    helper.setFont(font);
    // Note that the wrapping width needs to be set to zero before
   // getting the text's real preferred width.
    helper.setWrappingWidth(0);
    helper.setLineSpacing(0);
    double w = Math.min(helper.prefWidth(-1), wrappingWidth);
    helper.setWrappingWidth((int)Math.ceil(w));
    return Math.ceil(helper.getLayoutBounds().getWidth());
  }
  
  static double computeTextHeight(Font font, String text, double wrappingWidth) {
    return computeTextHeight(font, text, wrappingWidth, 0);
  }
  
  static double computeTextHeight(Font font, String text, double wrappingWidth, double lineSpacing) {
    helper.setText(text);
    helper.setFont(font);
    helper.setWrappingWidth((int)wrappingWidth);
    helper.setLineSpacing((int)lineSpacing);
    return helper.getLayoutBounds().getHeight();
  }
  
  static int computeTruncationIndex(Font font, String text, double width) {
    helper.setText(text);
    helper.setFont(font);
    helper.setWrappingWidth(0);
    helper.setLineSpacing(0);
    // The -2 is a fudge to make sure the result more often matches
    // what we get from using computeTextWidth instead. It's not yet
    // clear what causes the small discrepancies.
    Bounds bounds = helper.getLayoutBounds();
    Point2D endPoint = new Point2D(width - 2, bounds.getMinY() + bounds.getHeight() / 2);
    return helper.impl_hitTestChar(endPoint).getCharIndex();
  }
  

  With that, I am able to determine the amount of text can be put into the label, without the chain of ellipsis appears.

• Animate the edge - how to change the size of the stage without changing the element of the scene &amp; the size of the element?

  Hello

  I've created a demo using lively edge, the size of the demo is 1280 x 720. After that I want to change my size to 1280 x 600. But when I change dimension, the element in the file also change its dimension.

  For example - original size is 1280 x 720 & my element is rounded circle.

  When I hid it at 1280 x 600, the rounded cicle convert oval.

  but I want the same element of dimension to the stadium.

  Help, please...

  How you resize your internship?

  On the edge resize your stage normally does not affect the size of items on your stage.
