• Measure a sum of the widths of elements in an array?

  Hi all... is possible to: measure a sum of the widths of elements in an array? I can't figure it out and do not know if it is possible...

  Thank you!!

  If they are on stage, Yes.  just them summarize:

  function widthF(a:Array):Number {}

  var s:Number = 0;

  for (var i: Number = 0; i<>

  s += [i] ._width;

• Last element of the array

  Hello

  Running mod, when I add elements in the table, I want to see in the last element of the array automatically.

  How can I do that. (without using the vertical scroll bar).

  

  In a thousand words or less.  Nodes property allows you to programmatically access the properties of the objects.

  (Yes, you will need to run twice to see the result I have no default value)

  Hi Stacey Nathan,

  To remove the items from right toolbar, click Tools at the top.

  Then open the fall down to the accessibility or analyze and select 'delete the shortcut '.

  In a similar way, select "Add a shortcut" in the Tools drop-down menu to add to the tool on the right pane.

  Let us know if you need help.

• How can I view all the elements of an array?

  Hello

  I'm learning about the handling of tables.  The example finder includes this one, 'build array_forum.vi', which shows the two modes, concatenate and adding, I understand, HOWEVER, I can't understand how they built this vi.  For example, I can find the Array function to build, but I do not understand how they created the "digital data table 1" "data table 2" digital... etc, and I can't find the functions on the pallets that cause display "build the CONCATENATE entries table". ".  Where are these blue functions?

  Where these functions are found in the palette, and how we build them like that?

  The other vi indicated here, 'for loop array_forum.vi' is my attempt to reproduce, but it doesn't show all the elements of the array; However, it only displays a SINGLE element, the last element of the array.  How can I view all the items in the table I am creating using the FOR LOOP?

  Thank you

  I think I posted this in the wrong place.  I reposted it on the forum of Labview.

• How to view the last element in a dynamic table 1 d

  Hello..

  I want to display the value of the last element in a dynamic array 1 d... / I mean... If I stop the vi race, I need to display the last element of the array... How can I do this?

  and is it possible to use a button to start the vi... instead of using the Run button on the face before of the vi?

  An array of index!.  Size of table allows to determine the size of your array, subtract 1, that feed into the terminal array of Index index.

  You start the VI running somehow.  It can be assigned to run when opening.  Assuming that what you want is a way to type values in a front panel, press a GO button you created on the front panel, then have the real part of the VI to run.  You can use a structure of the event.  Or put a while loop at the beginning with a small wait next statement which basically just asks the GO button.  When you press this button, the Boolean value true stops the whole loop and allows the program to move on the main body of your program.

• The value of property to an array element node: How does it work?

  As I tried in vain to understand my shipment of samples recent misconception (here), I came across a behavior that I'm not sure I understand.

  Here it goes:

  Move a table of numeric values to the FP show. a few items. The easiest way is to take a 'table - Numeric (Silver)' pre-formed object with 3 items listed.

  Now, right-click on the top element and select: create > property node > value

  Change this to write about the BD and to connect a constant, say 1. Run the VI, you get this:

  ===>

  So far so good.

  Now do the same for the THIRD item and wire a different constant to the AP, say 3. Rerun the VI, you get this:

  ===>

  All right...

  I mean, it is not already made a lot of sense, but wait what will happen...

  Now remove the first NP and run VI again:

  ===>

  Quite logical, right? ... not!

  At least * I * can't make sense of it and it smells like a bug to me... or a weird feature.

  Tested in LV 2013 SP1 (62 + 2 bits) on Windows 7 64 bit.

  You create a shortcut to write to the ArrElem.Value property.  The property ArrayElement to a table is a little funky, it is the last element that was active.  With only a single PN on your comics in writing a value, click in the central element of the array, and then run the VI, repeat for the other elements.

• 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).

  

• 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.

• 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.

• Last element in the chain

  Hi all

  I have a string like this:

  55.000000; 10.000000; 0.100000; 1.000000; 1.000000; 0.100000; 0.000000; 0.000000; 1.000000; 1.000000; 22.000000; 0.100000; 6144.000000;

  The length of the string is not always the same. What I want is to have the last element. That is to say in this case 6144

  One way is to get the length of the string and using a subset of the string to get the last element. But to do this, the length must be always constant.

  Y at - it another way to get the last element independent of the length of the string

  Thank you

  

  Since you have the extra semicolon at the end, I actually caught the element from the second to the last of the table after the string of worksheet to the table.
