• How can I index an element of the array as "index Board" function to labview?

  Hello:

  I am looking for a method to search an array with indexes and return the element specified by the given index.

  as the array index of the labview function, but I can't find an exact symbol in teststand-table-operations/functions.

  I am new to teststand and everyone knows how to use labview in teststand.

  anyone can teach me?

  Thanks in advance!

  Thanks anyway, found in the API

• Access to the elements of an array passed as object reference

  Hi all!

  I am quite new to TestStand and therefore, my question might be simple enough but I was not able to find the solution by looking at previous posts.

  I have a sequence that passes a custom array (of data type) to another to make basic on the table stuff (reverse the order of the elements, for example).

  I want to move to the sequence called an object table reference

  The problem is that I am not able to read the array element inside the sequence called using the object reference.

  I found the way get the number of items, but I'm not able to access the item

  In addition, the TestStand GUI is able to let me see the array pointed to by the object reference that is passed within the known sequence, so it is possible to access... but how?

  I want to do operations on the object reference passed within a 'No return' TestStand if possible.

  Thank you very much.

  In other words:

  How do I access the field 'temperatureTag' item number '0' from the object variable reference referenceToClone?

  Locals.referenceToClone [0] .temperatureTag does not work...

  

  I don't know what is the recommended method to solve your problem. When you try to few alternatives, I was able to get the value required by the following expression (tested with TestStand 2014):

  Locals.referenceToClone.GetPropertyObject("[0]",_0).temperatureTag

  Try and tell me if it works for you.

  Use this workaround with caution.

• How to replace (assign) a part of the elements of an array in TestStand?

  Hello

  I would like to replace or assign values to the elements of an array.

  For example, I have a local variable with 6 elements, Locals.A = {1, 2, 3, 4, 5, 6},

  and I would do it is {1, 2, 13, 14, 5, 6}.

  Accordingly, I add an expression and write "Locals.A [2.3] = {13: 14}", but it failed.

  Is it possible to replace a part of a painting?

  My real question is I want to pass parameters to a sequence to a local variable of the MainSequence, like the picture as an attachment.

  I hope that I can assign the parameter (table 5 elements) for the range of 5th to 9th item of the local Variable.

  Could someone give me any suggestions? Thank you very much!

  

  (1) I meant move the entire table and in the subsequence programmatically update only a subset of the items.

  For 1 or 2, you'd have to write a loop as interates on and updates the items that you are interested in. There is no simple syntax that will do what you want. You can use a loop but, rather than make a statement of entitlement for each item.

• Change the properties of a cluster element inside an array of clusters

  Hi all

  I have a table of cluster that has the shape of a line with different elements of the screen.

  A list or a tree would not have made it, so I had to use a cluster and make a.

  The problem is I want to change not only the text but also the color of the text.

  Individually.

  I found this:

  http://www.NI.com/example/30904/en/

  But it changes the property in all groups in the table, not just the one I need.

  Some people have the same problem:

  Obviously, even if in a table/list or a tree, you can change the property of an individual

  cells (font, color), you can't do it in a cluster network, by a kind of magic.

  the property of an element of the cluster (font, color) are all connected together, so made

  the use of a table without value.

  A possible hack is available using masking of control, a visible setting and the

  other invisble, exchanging their position, whatever. This is a hack you have to perform,

  Therefore, add another code to maintain.

  Is that still the case, or is it now a more formal way to manage the individual cluster

  Properties, not only its data? After all it is a common example of a real life which should

  managed by Labview. In my opinion.

  Altenbach says:

  One of the elements could be an indicator of 2D about the same size image. You can create text in any color using the features of the image.

  Here's what I had in mind. Seems to work very well (I would refine the border picture fonts, etc., but this should help you get started).

  

• Reference to the array of Clusters with an array element

  Hello

  I have an array of clusters of CONTROL (qualifying as "upper-tier cluster table") with one of the items is an array of cluster cluster (see attached).

  I intend to "reference" of this cluster of high level at different screws (as add item VI, insert item VI, delete the item VI etc.) and access (add/edit delete) the elements of this array.

  

  In my code, how I cataloged the array element (cluster) on the cluster internal (as shown on the figure)?

  I use LV RT on PXI.

  

  Hello smercurio_fc,

  Thank you for your example! Just a question: actually, with shift registers, is an example of creating a local copy of the full range? Even if the value of the lowest level cluster is changed, is the complete table is updated at the end (registry value to offset the full picture at the right end is updated using the reference node and property)? This VI will be slow when the size of the array becomes great?

  Comment of nicely.

• mathematical calculation in script on each element of the array.

  Hi all

  I am trying to write the VB script in which I want to do different mathematical operation on each element of channel-specific data. For example, for each element I want to find the next two index given way and both before and after publication of the results on the basis, then it is more calculating.

  It will be very useful if someone can guide me in the execution of operation on the elements in the array inside the script of tiara, that we can do in labview using indexes in the table. There are built-in math and statistics in tiara tab analysis tool. But I want to design for my custom mathematical operation.

  Thnks

  Hi HS,

  Here is a version 10.2 tiara from what I understand ask you:

  Window = 2

  Denom = 2 * window + 1

  Threshold = 10

  Chnum = CNo("[1]/Speed")

  FOR i = 1 + ChnLength (Chnum) window - window

  Sum = 0

  FOR j = i - window to i + window

  Sum = sum + ChDX (j, Chnum)

  NEXT ' j

  Ave = sum/Denom

  IF Ave > threshold CAN

  ' do action of contingent

  END IF

  NEXT ' I

• Resize the array element programmatically

  Hi, I need to programmatically resize the element of a matrix. The external framework of the matrix control must take the same size, but the internal element should chang size programmatically.

  

  I have found no property/method to do this. Wait using Xcontrol I guess.

  Any idea?

  Thank you.

  Of your image that you inserted, I guess your "matrix" is a display of 2D LED array.

  In order to resize these elements all in now the 'original size of the matrix", you must implement two steps:

  1 resize LEDs:

  • Get ArrayElement reference
  
  
  • Convert the reference to Boolean
  
  
  • Set the width and height for the Boolean value of the new value

  Please note that now change the size of all THE LEDs. This is because all items in a table share the same properties (including size) with the exception of the "Value" property

  In addition, the table shell is resized as it still shows the same amount of LEDs (columns, rows)

  2. calculate the new number of columns/rows to keep the table shell roughly the same size

  • Calculate the multiplier for resizing in each direction (led to half size smaller multiplier of 2 to the number of lines/columns each)
  
  
  • Multiply the number of rows/columns of this multiplier (rounded)?
  
  
  • Set the size property of dimension to the hull of the array to the new values

  Please note that this will be 'resize the table to about the same size as it did before. Resizes rounding issues very likely (it has no LED 0.5 available!)

• 'Replace the element of the array' replaces not only indexed items

  Hey masters LabView,.

  Fairly new to Labview and I'm trying to sort out how to create a table of images. I know that the total number of images I want in my 'stamp' (not the buffer of LabView), so I'm the initialization of an array of this size. Can I bring this table in a loop For with a shift register, and I want to capture images and write them in the table of the buffe continuously (a comment: I do a circular buffer, but I don't want to implement in LabView, because there a lot of things that I don't need and I will eventually have to the process to be as thin as possible).

  Here's the problem (I assume an implementation, that does not decompose LabView):

  I expect:

  AN element of the array, in the position indicated by the index of the loop [i], is replaced by the image newly caught

  I get:

  All THE elements of the array becomes the image newly caught.

  (I can tell because I taste under the table, grabbing a single image from a constant "Check Array" index - may 7, for example.) But my index of the loop [i] value is 13, and the subsample becomes again the image newly caught.

  What a ridiculous thing I am doing wrong?

  Any help would be greatly appreciated.

  

  Ah, I just noticed something.  Initialize you an array of references at the beginning of your program, but it is a complete picture OF THE SAME REFERENCE: you must call the IMAQ Create in a loop so that you actually get unique references in your table.  You must have a different NAME for each image.

• Remove the array without the local Variable element

  I am wanting to know if you can remove an element of an array, the index of the removed part.

  and update the value in the array to not include the deleted part of a more direct way than the following:

  

  Or, in my program, the table is initialized with some clues that makes the task of removing an element of

  table, the part removed from indexing and updating the table includes only not the deleted part similar to the following:

  

  (a) is there a way to do this without having to use local Variables?

  (b) I would be so concerned to rid my program of all local Variables? (even those who don't create race conditions)

  Keep the table in a feedback node initialized in the world. Do not imply not objects of façade.

• Type a table defined clusters to hold configuration data - definition of default values for each element of the array

  Hello

  I was wondering if I could get some information and opinions on the use of an array of type defined clusters to store configuration data.  I am creating a program to test several EHR and wanted to have a control of type defined for each HAD with the information needed to create the DAQmx tasks for all signals for it must HAVE.  I am eager to do so that the data are encoded in hard and not in a file that the user might spoil.

  Controls of type def are then put into a Subvi who chooses as appropriate, one based on the enumeration of Type DUT connected to a case structure.

  I have problems with the control of the defined type.  I see issues when you try to save a configuration unique to each element of the array in the array of clusters.  Somehow, it worked at first, but now by clicking on "Operations on the data--> default font of the current value ' on individual elements of the cluster or the entire cluster (array element) does not save data when I re - open the command def.  What I am doing wrong?  I'm trying to do something with the berries of the clusters that I shouldn't do?

  I enclose one of the defined reference type controls.  I tried to change it bare to see if that helped, but no luck.

  To reproduce, change the resource string for the element 0 of the array and do the new value by default.  Then close the def of type, and then reopen it.  The old value is always present in this element.  The VI is saved in LabVIEW 2012.

  The values of a typedef are not proprigated to the instances of the control. They get if created WHEN data values have changed. They will be not updated with the changes to come. You must create a VI specifically to hardcode your values or to implement a file based initialization. The base file would be much better and more flexible. If you don't want users to change the data simply encryption. There is a wedding blowfish library that you can download.

• Changing the properties of the individual elements in the array

  In the attached VI, I have a table 1 d of the slider ('Phase Coefficients') controls where each element of the array represents the coefficient in a polynomial of arbitrary order. The problem I have is that the range of slider, I put to the coefficient of the lowest order (element 0 of the array) becomes quickly impossible for one more order coefficients (> 5 elements). Small changes in the highest order coefficients dramtically change the global polynomial.  I want each element/slider to have its own line, but I know that's not strictly possible that each element of a table shares the same properties. I've implemented a work around (use boolean to activate) in which the range of all cursors is set according to which the item is viewed, but my implementation prevents the modification of the range during execution of the VI. Is it possible to adapt my method (or use another method all together) in order to allow different, editable for each slider element ranges?

  Thank you!

  Each element of an array must have the same properties.  They can only differ in value.

  You can have an array of clusters, and each group can have the slider control.  Here, you will be able to regroup a slider with different properties in the cluster build clusters in a table.

• How to find feel it between the elements in an array

  Hi guys,.

  It is easy for you probs, but how can you find the diffence between all elements in an array?

  for example array = 1 2 3 4 5 6

  so difference between 1 and 2 is 1, the difference between 1 and 3 is 2. all the way to the hollow of the differece between 6 and x is x etc.

  I tried using shift registers, but just can't get enough.

  Thank you

  No need for the outer loop.

• Drag and drop the element of the array of Clusters

  I have a project that includes an array of 'tests', each of which is a cluster that contains an array of 'numbers', a matching the regular expression string and an array of "tasks" (all of them, is in turn, a group of elements).

  It is:

  • Tests (table of):
  • • Cluster:
    • • Reference numbers (an array of strings)
      • Regex (string)
      • Tasks (table of):
      • • Cluster:
        • • Task type
          • Basic channel,
          • Measuring channel
          • Other channels

  I wish I could drag and drop to rearrange the task table in an individual event.  (It is a nice-to-have rather than a urgent request - more for my own learning that no matter what).  For now, I've implemented "Move up" and "Move down" buttons

  Examples are fine for a single cluster that includes a table or an array of objects.  As soon as we have an array of clusters, it is difficult to access individual items within a specific cluster.

  Who that it be completed can drag and drop into such a facility?

  Curiously,.

  Geoff

  Hello GeoffF,

  It's certainly doable and you can even use the standard start drag and drop methods/events, the trickiest part is to determine the table of the elements that are selected on the mouse towards the top/mouse downwards and the swap of manual handling.  Fortunately, there are a few decent examples of how do this out there already, I suggest you take a look at this one:

  Example of community: determine the Index of the clicked element Array in LabVIEW

  https://decibel.NI.com/content/docs/doc-22434

  That should give you the selected table indexes, and then all you have to do is to move the elements around around the drop event.  I have attached a very basic demonstrative example that uses this code I just linked (you need to download that as well) and the events referred to swap two elements of the array.   The attached code is just thrown together, you'll want to design something more robust and scalable to any sort of actual use.

  Kind regards
