• How to change the frequency of sampling DAQmx during execution?

  Hello guys. I'm using LabVIEW in the measures of the frequency response function. My application requires the sampling rate to change according to the frequency of the signal during execution.

  I tried to do it with a "structure of the event" and it works well when I change the rate manually via the front control but it backs do not work when I set up the sampling frequency to vary automatically (just a frequency sweep). Photos below:

  Why not the structure of the event feels the change in the value of "rate"?

  Thanks in advance for your help.

  Lucas

  Hello

  In "automatic mode" to change the sampling rate, the calculated rate is written in the local variable (as illustrated in the code).  Structure of the event does not change value in the local variable as an event.

  In order to make the structure of the event to recognize the change in value of an indicator such as event: write the new value to the property "Value (Sgnl)" corrosponding node to rate indicator (see figure below).  This will make the structure of the event accept the value change in the indicator as event.

  Note: Use architectures such as producers and consumers for such applications, which makes the application readable and expandable.

• 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.

• Changing the properties of the element during execution

  Is it possible to change the properties of the element when running on APEX. I'm looking for the equivalent to SET_ITEM_PROPERTY command in Oracle Forms.

  Yes, I want to

  It's the $x('P1_ITEM').size = number_of_chars_you_want

  P.S. Check this site: http://www.w3schools.com/HTMLDOM/
  It contains most of the properties of the DOM element.

• 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;

• Cannot view or change the signals in the timeline

  I'm pretty new to FCPX. But I know that I did this particular thing last week. I want to disappear a song at the end of my film. But the waveform for the song is not useful or editable. It's a very narrow (green vertical stripe in my calendar. There is a barely recognisable dark grey line through the song in the timeline panel, but I can't find any way to extend this option to make the actual waveform visible so I can put handles on it, and do the fade. I can't find all the commands to make the visible waveform.

  I tried the thing helps in FCPX and I tried the Apple on FCPX book, and I searched the internet. On the net, there are a few references to the problems of that kind for several years, including a command-W command option, which does not, so it must be an old key combination.

  I haver restarted Final Cut, I restarted my computer. Nothing helps me. What is the scoop, people? Am I missing something really obvious? Thanks for your help.

  You need to Clip Hight taller.  In the lower right pane Timeline is a menu to do with.  See the section "clip timeline and hight Adjust appearance" here.

• ScatterGraph does not manually change the axis to execution interval

  I use the ScatterGraph and the WaveFormGraph in VS2010 Winforms application.  I have the interaction mode axes set to EditRange.  The WaveFormGraph command allows to edit the axis range by clicking on the end of the axis labels and modify them.  ScatterGraph control is not even though the documentation I've read says it should.  The mode of the axis does not seem be the question that I have changed between fixed and AutoScaleLoose (which is not the choice to have everything showing changing data, if you want your range entered manually to maintain).  I tried a new project with a ScatterGraph control with the default settings and checked that it does not change the axis interval.  Is there a way to change the settings to allow you to manually edit a ScatterGraph range in this way when running?

  Thank you!

  Hi Lybro,

  You have activated the "EditRange" of the graphical object of point clouds InteractionMode? There are two places that the mode of interaction is defined, one for the axis and the other for the scatter chart, both must be enabled for writing at work. I just tested this with Measurement Studio 2013 and it works. Let me know if it helps.

  Kind regards
