• array element references confused me

  Then... I'm playing with references to arrays, specifically references to items in a table.

  It seems that I should be able to read the value of the table, but because of how I am tying TestStand and LabVIEW, I am trying to create a utility that automatically obtain data back between the LV and TS, where the types of data passed back are completely unknown and, possibly, paintings of beams that have tables nested clusters.

  I try to walk the LV data structure and reference TestStand and get the right data.  However, I can't seem to be able to use references to point to specific elements of a table - see example I expect the high and the low code works the same, but they do not.

  Any suggestions on what I do wrong to get the top and bottom to work the same?

  Property of the array element node gives you a reference to the element that makes up the table.  So if you set the properties of a digital control maybe to change the color or display format.

  Is not a way to get or set the value of a specific array element.  To set a particular array element, you must use replace table subset.  To get the value of a particular array element, you use table to index.

  Indexvalues property node is used to determine which is the first item that appears.  It changes the value of the indexer the upper left corner of the table.

  One thing I noticed that I don't know if I knew before, it was this setting the property value on the reference of array element, node will have an impact on the first element of visible table.  If you turn the highlight performance and play with array index, while it is running, you will see that the resulting table will be different.

  Although it IS possible, you can not do after seeing what it takes.

  We can get the value of an array element that is in a control or indicator provided it it the upper left display element.

  This nugget exploits that factand see how it can be done. Note: I have not tested this code lately so I don't know if NEITHER broke this behavior since the writing of this nugget.

• 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.

• read part of an array element

  Hi all.

  As indicated in the title, I'm reading part of an array element.

  What I'm doing is reading a LeCroy scope values using a 'write' 'read' I returned the values in a table, but the question is the scope returns a value of "1, 52.33E - 3".

  I just want the element to be 52,33 so I can use it for other calculations.

  For example, my table.

  ' 1, 34.334E - 3.

  ' 1, 53.343E - 3.

  ' 1, 143.232E-

  And I want it to be

  34.334

  53.343

  143.232

  Thank you!

  Use string functions (match pattern) to find the comma. Then convert the part after the comma to a number using the string appropriate to the Number function.

  Are throwing you what looks like an exhibitor intentionally?

  The last string seems to miss the exhibitor. This suggests you may have problems with your communications with the instrument.

• Get all the different values in a table - 'or array elements' does not work with I32

  Hello

  I just found out that "array elements or" does not work with a table 1 d of integer values. I didn't expect that.

  I did a semi quick forum search and did not find a pointer to an effective solution. Can someone give me a hint?

  Do not back my initial intention is to list all the values that appear in an array of integers.

  I thought that if I converted the figures for powers of 2 and or I had solved the problem at hand - only to discover that the elements of array does not.

  If someone could propose a different approach, I'd be happy too.

  I should mention that the execution time is a factor here - I need a fast code, but any suggestions are welcome because they could help me get started.

  Best regards Florian

  Hi Florian.

  try this:

  

  "Function, it seems, the table of GOLD ' is polymorphic (as written in the context-sensitive help), but does not support arrays of I32. At least the error message means just that...

• How can you specify the default value for the undefined array elements

  According to aid LV, the tables have two default values, the normal default value and the default value for the undefined array elements.

  I assume that there must be a way to specify the default value for later, but I can't find it anywhere.  Any ideas?

  I know that you can drag the item out of the table container.  Change the default value on this scalar element.  Then drag the item in table tank.

• A fundamental question/problem with the like undefined array element

  Hello everyone,

  Thanks for looking at my problem. I am very new script and javaScript, and I encountered a strange problem. I always try to solve all my problem myself, with documentation (it helps to learn) or as a last resort with the help of google. But in this case, I'm stuck. I'm sure its something very simple and elementary.

  Here I have a code that simply loads a text file (txt), load the contents of the file in a "var glad." This summary text file a font family name, every name on a new line, as:

  Albertus

  Antenna

  Antique

  Arial

  Arimo

  Front

  Barber1

  Barber2

  Barber3

  Barber4

  Birch

  Blackoak... .etc

  Now I hollow the variable content of loop, extract each letter and add it to the list '[i]' table. If the character is a line break the list [i] table adds another element (i = i + 1); That's how I separate each name in its own element of array.

  The problem I encounter is, when I have hollow loop table fontList and $.writeln (fontList [i]) is the result in the console :

  undefinedAlbertus

  undefinedAntenna

  undefinedAntique

  undefinedArial... etc.

  I don't get serious, where the undefined comes? As far as I tested each digit to be added to the array element, I see nothing extraordinary.

  ----------------------------

  Here is my code:

  #target illustrator

  var doc = app.documents.add ();

  Open the file

  var myFile = new File ("c:/ScriptFiles/installedFonts-Families.txt");

  openFile var = myFile.open ("r");

  check if it is open

  if(OpenFile == true) {}

  {$.writeln ("the file has loaded")}

  else {$.writeln ("the file does not load, check the name or the path") ;}}

  load the contents of the file into a variable

  var content = myFile.read ();

  myFile.close ();

  var ch;

  var x = 0;

  var fontList = [];

  for (var i = 0; i < content.length; i ++) {}

  ch = content.charAt (i);

  If ((ch)! == (string.fromCharCode(0)) (10))) {}

  fontList [x] += ch;

  }

  else {}

  x ++;

  }

  }

  for (i = 0; i < fontList.length; i ++) {}

  $.writeln (fontList [i]);

  }

  doc. Close (SaveOptions.DONOTSAVECHANGES);

  Thanks for any help or an explanation. If you have any tips on how to improve my practices or any suspicion, please do not hesitate to say. Thank you

  Hi vladac54380629,

  better, you try something like this:

  #target illustrator
  
  //var doc = app.documents.add(); 
  
  //open file

  fontList = content.split ("\n")
  myFile.close();

    }
  
  //doc.close (SaveOptions.DONOTSAVECHANGES);

  A note:

  The real font names may be different from your own list for example:

• How to access an array element?

  I'm trying to access a table on a click of a button element.  Complete creation, I have this: var = students ["Theo Arguna", "Leif Arneson", 'John Egan', "Sakura Nakahara", 'Rebecca Pilkington', "Debra Sutter"];

  the passage of the mouse button I put this:

  var myVariable = sym.getVariable("students.eq[0]");

  sym.getSymbol("message").$("Text4").html ("Click now to see" + sym.getVariable ("myVariable") + "working.");

  When I test I get "undefined" say where "$myvariable" is in the line above the code.

  Any suggestions on how to get the array element in this?

  Hello

  «"«You are almost there...»»»

  Put this in your creationComplete event:

  sets the variables table students

  sym.setVariable ("students", ["Theo Arguna", "Leif Arneson", "John Egan", "Sakura Nakahara", "Rebecca Pilkington", "Debra Sutter"]);

  And put it in your button mouseover event:

  get the array element you want

  var myVariable = sym.getVariable ("students") [0];

  sym.getSymbol("message").$("Text4").html ("Click now to see" myVariable + "working.");

• Tween an array element

  I created a script that will movieclips to fill the stadium. In this case, a ranking.

  each created movieclip is positioned and placed in a table.

  The problem becomes an array element and the power of tween it

  * I would like to experiment with tween different combinations to get them out of the scene. Here's what I got

  I am able to get the clips on the stage... [Can't get them off =]

  Import mx.transitions.Tween;

  Import mx.transitions.easing. *;

  Block = new Array();

  var Xposition:Number = 0;

  var Yposition:Number = 0;

  var stack:Number=Math.ceil(Stage.height/30);

  var Numofstacks:Number=Math.ceil(Stage.width/30);

  var fadeit:Tween;

  var n: Number = 0;

  for (r = 0; r < (Numofstacks); r ++) / / 25

  {

  PositionY = 0;

  for (c = 0; c < (stack); c ++) / / 3

  {

  var particle = this.attachMovie ("block", "gabarit@sur" + r + c, this.getNextHighestDepth ());

  Particle._y = PositionY

  Particle._x = which

  Block [n] = particle._name;

  trace (Particle._name)

  PositionY = PositionY + 30;

  n ++

  }

  Which = which + 30

  }

  runit var = setInterval (effects, 3000)

  effects function (): Void

  //{

  Yvan = new Tween (block [0], "_alpha", Strong.easeOut, 100, 0, 1.5, true);

  //}

  clearInterval (runit);

  Do not store the _name in table property, store the particle itself.

  Block [n] = particles;

• The search in a table a value then delete this array element

  Hello.

  I have an array of VO (id, link, title, url...) I want to get an ID of this array element and remove the element with the corresponding id. Any thoughts on how I would go to this topic?

  Thanks in advance!

  Ryan

  I don't know much on your and this probably isn't the most elegant solution, but you can do something like:

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

  {

  If (myVOArray [i] ["id"] is "someId")

  {

  myVOArray.splice (i, 1);

  }

• GPO sorting FlexField array elements is possible?

  Hi all.

  I have a table, this table contains more than one column, one of them is FlexField, which contain 7 columns.  Case in common, I put the column real SortAllowed property and it will work, but it does not work with FlexField. How can I fix this (if itn is possible)?

  I don't have a lot of time.

  Nice day.

  p.s Flex field has property Type: Descriprive.

  Hi Alex,

  Because Oracle does not sort on DFF, you can check if you need the FDF itself values (in function of the importance is the requirement of sorting). A solution could be to capture the columns in FACT as of the independent columns of the database in the custom table and allow to sort. But this way you'd lose the flexitbities provided by DFF.

• Extract the supplied index value of array element

  Hello

  A similar question might have been asked before, but I couldn't find one that exactly matches what I want. Also, I'm using labview 8.5 so could not read most of the views that you guys tied with other solutions.

  The files that I use are attached. Test_FIFO_TimeTagging-Nov16 - try1.vi is the main vi.

  The absolute time in milliseconds in the table of resorption. As can be seen, it is derived from the berries Micro2 and Macro2. I want the user can specify the duration, that is, whether the current item in the table of absorption has a value greater than the value of the user entered, so I want the index of this item in the resorption so that I can use this index to create Micro2 and Macro2 subtables that contain only items from index 0 to index I get resorption.

  I do not know how to retrieve the index of an array given the value of the element, so can't go forward.

  Thank you

  Hey Kaiser,

  the function that you need is 'threshold 1 d table '. (I guess that your time values are sorted, otherwise using subdashboards makes no sense...)

• Delete Array element

  I'm unable to a Board problem. I am able to do the types of features such as see how many items in the table, insert (I hope I did it correctly) and ordered random numbers growing as well as sorting.

  Now, I'm hoping to find a way on how to remove the 4th and 5th element in the array and then the display of the part which has been removed and showing the final result of the table.

  I'm tinkering with the structure of the table "remove table" and tried to use it, I even looked at the documentation and trying to hook up the wires, but I can't seem to get this to work?

  Hello LabVIEW321,

• Look for the string of the numbered array element.

  This is my first post, so I'll probably miss one thing or another.  I will look nothing missed as soon as possible. I write code LV to test additional County stored in a CSV text file. Counties represent the stimulated current of a diode in a beam of radiation. The product is a QA device for a medical radiation treatment machine. The Integrator output proportional to the current diode accumulates as a whole into account in the text file. My LV code puts the numbers in the tables, calculates the incremental time derived and analyzed statistically. Numbers of the columns in the table data represent unique components. Default number of data column is sorted in a 1 d table has no column number. As if not column 10 represents CR39 of PCB 11. I need an algorithm how to connect a string such as CR39-PCB11 to the element of the array 1 d failure or relate to the string to the column in the data table that fails. Could you suggest a way to do this?

  If I understand you correctly, instead of these numbers that are in the Updates (odd) 'zero', you want to get premium channels. For the moment, the operator uses a lookup table, to find the chain (component) that corresponds to the column number.

  It's easy, because you only need an array of strings (corresponding to the column number 0 n) and use the array index with the index of the column. Place it in a loop for get all the clues of failures (the loop autoindexing for).

• How to activate the filtering and sorting in a dynamic array

  Hello everyone,
  I'm going crazy with this problem, hope that someone could help me! I have a dynamic array based on a view that changes its application programmatically. For its dynamic nature, I did in my mainPageDef no reference to the attributes of the table:
  
  <>executables
  < variableIterator id = "variables" / >
  < iterator lie = "DLOV_1" RangeSize = "25".
  DataControl = "DLOV_AppModuleDataControl" id = "DLOV_1Iterator".
  R = "always" Sortable = "true" / >
  < / executables >
  < links >
  < Tree IterBinding = "DLOV_1Iterator" id = "DLOV_1" >
  < nodeDefinition Name = "DLOV_10" >
  < / nodeDefinition >
  < / tree >
  < / links >
  
  
  Jspx page I have:
  
  
  < af:table value = "#{bindings." DLOV_1.collectionModel}.
  var = "row".
  lines = ' #{bindings. " DLOV_1.rangeSize}.
  emptyText = "#{bindings." DLOV_1.viewable? "{'No data to display.': 'Access Denied.'}".
  fetchSize = "#{bindings." DLOV_1.rangeSize}.
  rowBandingInterval = '0 '.
  filterVisible = "true" varStatus = "vs."
  selectedRowKeys = ' #{bindings. " DLOV_1.collectionModel.selectedRow}.
  selectionListener = "#{bindings." DLOV_1.collectionModel.makeCurrent}.
  rowSelection = "single" id = "t1" >
  < af:forEach elements = "#{bindings." DLOV_1Iterator.attributeDefs}.
  var = 'def' >
  < af:column headerText = "#{def.name} '"
  sortable = "true" id = "c1".
  filterable = 'true '.
  filterFeatures = "caseInsensitive" >
  < af:outputText value = "#{row [def.name]}" "
  ID = "ot1" / >
  < / af:column >
  < / af:forEach >
  < / af:table >
  
  
  which works really well with the code of my bean (the one who changes the query and execute it):
  
  
  If (am.findViewObject ("DLOV_1")! = null) {}
  am.findViewObject("DLOV_1").remove ();
  System.out.println ("off");
  }
  ViewObjectImpl dLovView = (ViewObjectImpl) am.createViewObjectFromQueryStmt ("DLOV_1", (String) qryTxt.getValue ());
  dLovView.executeQuery ();
  AdfFacesContext.getCurrentInstance () .addPartialTarget (lovTable);
  
  
  Now the problem is I can't get the functionality of filtering and sorting of column. How can I achieve that? I noticed that you define the defName in the nodeDefinition to provide a 'model', but I can't do that because my table does not have a fixed structure.
  Is there a solution?
  Thanks in advance!
