Referencing Array element by name
Hi, I've got an array containing various sprites... I'm
wanting to reference the sprite I want by its name rather than its
index in the array, and was wondering if theres a simple way of
doing this? I know I could do a for loop through all the array
elements and see which one has a name that is equal to the name im
looking for, but is something along the lines of
myArray[elementName] possible?
It can be a sprite.
var testSprite:Sprite = new Sprite();
addChild(testSprite);
var myObject =
{valueOne:"one",valueTwo:"Two",valueThree:testSprite};
myObject.valueThree.x = 200;
trace(myObject.valueThree.x);

Accessing custom device FIFO array element by name
Hi,
Some of my custom devices have a large number if I/Os. Because the FIFOs are arrays, my custom device RT driver VI has been referencing them by indexing the arrays. Is there a recommended method to reference FIFO I/Os by name, and preferably the same name as the channel names that are created by the initialization VI? Referencing array elements by index can get very confusing and not very flexible if I need to add or remove custom device I/Os. Thanks.You could use an enum diagram constant to wire to the index terminal of index array. Make the item name correspond to the element name.

I know we can use local-name() to get the tag/field name,
but I have not idea how to get these leaf field names one by one and then mapping to every array elements.
I tried whole day but no successful
Does anyone have some idea?
Thanks very much!

TestStand2.0 generates for each result property ( data, limits, status...) of each array element in a NumericArrayTest an extra line in the test report.
How can I change this to display all result properties of one array element in a single line?
How can I reduce the spaces between the property name and its value in the report?
How can I delete the message: "Measurement[x]" and display only the Measurement Alias (named in the Edit Limits menu)?
This means I like to change my report from:
Measurement[0] (ADC1):
Data: 5000
Status: Passed
Measurement[1] (AD
C2):
To:
ADC1: Data: 5000 Status: Passed
ADC2: ...Hi,
What you can do, is use the Override Callbacks for Modify the Report that is Generated.
Also you can also change the report sequence 'reportgen_txt.seq' to achieve the desired affect. If you go for modifying the report sequence then copy this to the User folder and then make your changes.
In the Resources Library you can find simple examples were the report has been modified by either using the Override Callbacks or by modifying the actual sequence.
One other item in the Report Options you will have to set the 'Select a Report Generator for Producing the Report Body' control to use the Sequence instead of the DLL.
Hope this helps

A basic question/problem with array element as undefined
Hello everybody,
thank you for looking at my problem. I'm very new to scripting and javaScript and I've encountered a strange problem. I'm always trying to solve all my problem myself, with documentation (it help to learn) or in the last instance with help of google. But in this case I am stuck. I'm sure its something very simple and elementary.
Here I have a code which simply loads a text file (txt), loads the content of the file in to a "var content". This text file contents a font family name, each name on a separate line, like:
Albertus
Antenna
Antique
Arial
Arimo
Avant
Barber1
Barber2
Barber3
Barber4
Birch
Blackoak ...etc
Now, I loop trough the content variable, extract each letter and add it to the "fontList[i]" array. If the character is a line break the fontList[i] array adds another element (i = i + 1); That's how I separate every single name into its own array element;
The problem which I am having is, when I loop trough the fontList array and $.writeln(fontList[i]) the result in the console is:
undefinedAlbertus
undefinedAntenna
undefinedAntique
undefinedArial ...etc.
I seriously don't get it, where the undefined is coming from? As far as I have tested each digit being added into the array element, I can't see anything out of ordinary.
Here is my code:
#target illustrator
var doc = app.documents.add();
//open file
var myFile = new File ("c:/ScriptFiles/installedFonts-Families.txt");
var openFile = myFile.open("r");
//check if open
if(openFile == true){
$.writeln("The file has loaded")}
else {$.writeln("The file did not load, check the name or the path");}
//load the file content 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(10))) {
fontList[x] += ch;
else {
x ++;
for ( i = 0; i < fontList.length; i++) {
$.writeln(fontList[i]);
doc.close (SaveOptions.DONOTSAVECHANGES);
Thank you for any help or explanation. If you have any advice on how to improve my practices or any hint, please feel free to say. Thank youCarlosCantos wrote an amazing script a while back (2013) that may help you in your endeavor. Below is his code, I had nothing to do with this other then give him praise and I hope it doesn't offend him since it was pasted on the forums here.
This has helped me do something similar to what your doing.
Thanks again CarlosCanto

Label TS array elements from LV
Hi,
How can I change the Label of a TS array element from my LabVIEW code??? Se picture added.
It is done when you insert at ”Multiple Numeric Limit Test” step in a test sequence and select “Edit Limits…” you get the “Edit Multiple Numeric Limit Test” dialog box. When this is closed with OK the Names of the Measurement Set is applied to the elements in Step.Result.Measurement. How can I do this from LabVIEW???
I am looking forward to hear from you.

Accessing a user array elements in Captivate 6

alert(i);
alert(objCP.cpEIGetValue("m_VarHandle.questionList[2]"));
alert(value);
I'm attempting to create a list using a captivate variable I've created called "questionList".
I fill questionList with data and and then use that data to count, in this instance with cat1Len and cat2Len.
After that I attempt to verify that the data is being returned correctly with a series of alerts.
Here's the problem:
alert(i) correctly reports the number my incrementer should be at.
alert(objCP.cpEIGetValue("m_VarHandle.questionList[2]")) correctly reports the data in cell [2] of questionList
but...
alert(value) reports undefined. How can this be? I know that I can access array elements from inside this loop and I know that I my incrementer is at the correct location so what's the deal?

Problem With Referenced Array Loading
Hi. I'm working on the final lab for my java class at the moment, and I'm to create a program which reads a file containing transaction records, stores each record as an array element, and then prints various types of reports using the array of transactions. I've created a class called Transaction which stores all the data for each transaction, and the array used in my program is of type Transaction.
I'm not having any problems in writing the program, except there's something going wrong with my attempt to write a method to load the array. The method declaration is:
* Method to accept a file from the user and load its data into an array.
* Returns the number of elements added to the array.
public static int loadArray(Transaction[] transactionArray, int size) throws ExceptionNow, I'm under the impression (and my teacher confirmed this) that arrays are passed by reference. So I'm assuming that by creating an array in my main method, passing it into loadArray(), and changing the values within the method, all the data will be present in the array within main without having to explicitly return the loaded array.
However, as soon as I try to do anything with the loaded array, I get a NullPointerException. I opened up the debug mode, set a breakpoint in my main right after loadArray() is called, and it shows that every element in my array is null. I am at a loss as to why. If anyone can help me figure out why my reference array isn't staying updated as it's edited elsewhere, it would be greatly appreciated.
Here is my loadArray() code in case it would help, but there is no error in it's execution, as the same code directly in my main method works fine.
public static int loadArray(Transaction[] transactionArray, int size) throws Exception
int logicalSize = 0; // the number of transactions loaded into the array
int itemID; // the item ID involved in the transaction
int units; // the number of units in the transaction
double unitCost; // the cost of each unit in the transaction
char type; // the type of the transaction
String date; // the date of the transaction
String fileName; // the name of the user selected file
String record; // the current record in the file
Scanner file; // reads input from a user selected file
Scanner parse; // reads input from the file's current record
transactionArray = new Transaction[size]; // creates a new array for the new data
System.out.print("Please enter a file name: ");
fileName = input.nextLine();
file = new Scanner(new File(fileName));
record = file.nextLine(); // discards the initial line of headers
while(file.hasNext())
// grab the next record and parse all its data
record = file.nextLine();
parse = new Scanner(record).useDelimiter(",");
date = parse.next();
itemID = parse.nextInt();
type = parse.next().toUpperCase().charAt(0);
units = parse.nextInt();
unitCost = parse.nextDouble();
transactionArray[logicalSize] = new Transaction(date, itemID, type, units, unitCost); // loads the current transaction into the array
logicalSize++;
return logicalSize;
}Thanks!
Oh, I guess I should also add that the variable input is a global variable of type Scanner.
static Scanner input = new Scanner(System.in); // reads input from keyboardMessage was edited by:
Kristofer.WardNow, I'm under the impression (and my teacher confirmed this) that arrays are
passed by reference.Java passes references to arrays by value.
So I'm assuming that by creating an array in my main method, passing it into
loadArray(), and changing the values within the method, all the data will be present
in the array within main without having to explicitly return the loaded array.Bearing in mind my statement above, what really happens is that a reference to
the array you created is passed to loadArray() by value. What I mean by that
last bit is that your loadArray() is free to assign a reference to a completely
different array to its argument variable and the caller will not notice the change.
That's what's happening here:public static int loadArray(Transaction[] transactionArray, int size) throws Exception
// declarations of local variables
* The argument variable is now assigned a reference to a completely
* new array. When this function returns the variable the caller used to
* invoke this method will have exactly the same value it did before this
* method was invoked. Ie it will *still* refer to an array of nulls.
transactionArray = new Transaction[size];
// more stuff - that involves changing the contents of
// the newly created array, not the one the caller has
// a reference to.
return logicalSize;
} -
How to modify array elements from a separate class?
I am trying to modify array elements in a class which populates these fields by reading in a text file. I have got mutator methods to modify the array elements and they work fine in the same class.
public class Outlet {
private Outlet[] outlet;
private String outletName;
private int phoneNumber;
private int category;
private int operatingDays;
static final int DEFAULT = 99;
public void setPhoneNumber(int newPhoneNumber) {
phoneNumber = newPhoneNumber;
public void setCategory(int newCategory) {
category = newCategory;
public void setOperatingDays(int newOperatingDays) {
operatingDays = newOperatingDays;
public static void readFile(Outlet[] outlet) throws FileNotFoundException {
Scanner inFile = new Scanner(new FileReader("outlets.txt"));
int rowNo = 0;
int i = 0;
String outletValue;
while (inFile.hasNext() && rowNo < MAXOUTLETS) {
outlet[rowNo] = new Outlet();
outletValue = inFile.nextLine();
outlet[rowNo].setOutletName(outletValue.toUpperCase());
outlet[rowNo].setPhoneNumber(DEFAULT);
outlet[rowNo].setCategory(DEFAULT);
outlet[rowNo].setOperatingDays(DEFAULT);
inFile.close();
public static void displayUnassignedOutlets(Outlet[] outlet) {
int i = 0;
System.out.println("Showing all unassigned Outlets");
System.out.println(STARS);
for (i = 0; i < MAXOUTLETS; i++ ) {
if (outlet.getCategory() == DEFAULT) {
System.out.println("\nOutlet Number: " + (i + 1) + "\t" +
outlet[i].getOutletName());
Now in the other class that I want to modify the array elements I use the following code but I get an error that "The expression type must be an array but a Class ' Outlet' is resolved".
So how can I modify the array elements? What do I have to instantiate to get the following code to work?

Using a For Loop Index for Array Element Number?
Hi. Thanks in advance for the help. I can't seem to find what I want to do here using the search function... probably because I don't know how to frame the question appropriately. Ignore the title to this post cause it's probably wrong vocabulary for what I want to do.
Here's the situation:
I have a 2D array where the first column is the X data and each subsequent column is Y data (call it Y1...Yn). The n-value varies from run to run (some runs have 4 columns of data, some have 20), but that is easily gathered when reading the data file. I need to perform a number of operations on each set of data, the least of which is smoothing the data and graphing it, so I'm limiting my discussion to these 2 operations.
What I want is a for loop structure where the indexing of the loop tracks the Y1...Yn columns, grabs each column for the iteration, performs the relevant analysis, and spits out the result, but in a stackable manner. Thus the title; I want to use the for loop's index to mark the array element for building a new array.
See the image attached. A 2D array of 9 columns (X, Y1...Y8) is analyzed such that each data set, (X, Y1), (X, Y2)...(X, Y8) is bundled, graphed, run through a B-spline Fit, of which is also graphed. I need to replace this with something that looks like the for loop structure shown.
I just don't know how to get those two data bundles [(X, Yi) and it's smoothed pair] out of the for loop in a stacked set from every iteration of the for loop.
Again the title, I think I want to build a new array where i use the index of the for loop to control the entries of the new array. But I can't see how to do that.
Any help would be appreciated.

NeedForLoopForThis.PNG 30 KBHello H.R. Dunham, and welcome to the forum!
It seems that you may be looking for Auto-Indexing, a basic feature of loops in LabVIEW. You'll need to transpose your array before wiring it into the for loop, as elements are auto-indexed by row before column, but at that point you should be able to operate on each column and output an array of n cluster elements corresponding to your input columns. Auto-indexing tunnels look like brackets to indicate each element will be indexed automatically- this should be the default when wiring an array into a for loop or when wiring anything out of a for loop.
As for how to build your pairs, I suggest removing the X column and creating a "starter" cluster containing your X data and placeholder Y data before entering your "Y" processing loop. Use the bundle by name function in the for loop to insert your processed column data into the cluster and auto-index the cluster output. Flow would be something like this:
1) Gather data
2) Split X and Y using standard array operations
3) Create "template" cluster with shared X data
4) Pass template cluster and Y-column array into an auto-indexed for loop.
5) Insert processed Y data into cluster inside loop.
6) Auto-index cluster data out of loop.
This tutorial is probably also a good place to get started:

Initializing array elements on a static initialization block
Hello,
I have this class:
class Foo{
public static Wing[] flights = new Wing[20]; //initialize with null Wing references
static { //static initialization block - begin
for(Wing w : flights){ //for each Wing slot on the array,
w = new Wing(); //create a Wing object and refer to it
} // static init block - endThe code above creates a Wing array, and the static init block should create 20 Wing objects on the array slots, but the objects are lost when I try to use it in the main method on the same class Foo:
public static void main(String[] args){
System.out.println(flights[3].name); //will throw NullPointerException -> Array elements have not been initialized
}How is that possible? The init code for(Wing w : flights) looks like has created copies of the objects, and not just references to the same object. If I change the static init block to the "old-fashioned for loop"
for (int i=0; i < flights.length; i++){
flights[i] = new Wing();then it works.
But I think that the problem is not on the kind of for loop itself, because if I use same static initialization statement, with for (Wing w : flights) on the main method, instead of in a separate init block, the array gets populated with solid objects.
Any ideas of what I am doing wrong?
Java version: 5.0I think I got it. I am reseting the reference to point to a new Object in the heap instead of the array slot. :-P

Found character data inside an array element while deserializing
Hi Experts,
When I am trying to execute the webservice I am getting the following error
Found character data inside an array element while deserializing
Actual structure is as follows

I know XI doesnt support array types thats why I have created my own structure as follows
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="retrieveInventory" type="InvArray" />
<xsd:complexType name="InvArray">
<xsd:sequence>
<xsd:element name="pOutletList" type="xsd:string" maxOccurs="unbounded" form="qualified" />
<xsd:element name="pSkuQuantityList" type="xsd:string" maxOccurs="unbounded" form="qualified" />
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
This webservice takes input like
storenumber1;storenumner2....
item1,qty;item2,qty.
I am passing values like this to my webservice. But still I am getting the same problThe problem doesn't seem to be related to the XI system. Have you done any configuration at receiver Webservice to convert the string data passed through XI into string array data? I think there is a mismatch in what XI sends and receiver expects.

How to access XML elements by name in Extendscript??
I'm almost done the script that I've been working on, but something has been nagging me since I started. When I did start, I looked at the JS Tools Guide CS5 that comes with the extendscript ide to check how to access XML elements, children, attributes etc. It says this:
The XML object represents an XML element node in an XML tree. The topmost XML object for an XML file
represents the root node. It acts as a list, which contains additional XML objects for each element. These in
turn contain XML objects for their own member elements, and so on.
The child elements of an element tree are available as properties of the XML object for the parent. The
name of the property corresponds to the name of the element. Each property contains an array of XML
objects, each of which represents one element of the named type.
So basically it converts the XML into JSON. And you can access the properties like so:
<book category="COOKING">
<title lang="en">The Boston Cooking-School Cookbook</title>
<author>Fannie Merrit Farmer</author>
<year>1896</year>
<price>49.99</price>
</book>
The Javascript statement bookstoreXML.book; returns the entire list of books.
The statement bookstoreXML.book[0]; returns the XML object for the first book.
The statement bookstoreXML.book[0].author; returns all authors of the first book.
A couple pages down it talks about Retrieving contained elements using children(), elements(), descendants().
So now I look through the XML Object properties and I see that I can use:
xmlObj.child (which) which A String, the element name, or a Number, a 0-based index into this node’s child array.
or
xmlObj.descendants ([name])
name Optional. A String, the element name to match. If not provided, matches all
elements.
or
xmlObj.elements (name);
name Optional. A String, the element name to match. If not provided, matches all
elements.
This is an excerpt of an XML I was working with:
<ROW xmlns="http://www.filemaker.com/fmpdsoresult"
MODID="16"
RECORDID="11128">
<Sign_Type>251.dr</Sign_Type>
<fm:Location xmlns:fm="http://www.filemaker.com/fmpdsoresult" xmlns="">5-5024</fm:Location>

R522 - R446 even
Xavier Elevators
Zone

R537 - 5757 odd

</ROW>
Extendscript will not give me an anything when I try to access elements by name. Instead I have to access by index, which works, but I'd rather search for names!
Actually the console log returns: <![CDATA[]]>
What am I doing wrong!?First, those E4X XML objects are definitely no JSON (plain data) - they have a multitude of methods, even for tasks that would easily be implemented as property (e.g. the length() function), and they also bind xml element and attribute names onto the objects, allowing to target a multitude of XML nodes with a single statement. Or did you mean your script with that "it"?
Anyway, as you found out the ExtendScript XML object handles namespaces mostly by hiding them from you.
You could play around with global namespace settings, see the JavaScript tools guide.
You could also explicitly specify a namespace. This works for me:
$.writeln(myXML["fm:Location"]);
For simple use I had most success with a brute force approach that just strips the namespaces.
function removeAllNamespace(xml)
var ns =new Namespace();
var d=xml.descendants();
for (var i=0;i<d.length();i++)
d[i].setNamespace(ns);
