Testing array elements
Hello,
This might be a very stupid question, but I did do quite a bit of searching and haven't found the answer. I'm trying to test the value of an array element and not sure how to do this. Here's the code:
public static void Fibbonacci(int end){
Integer[] f = new Integer[end];
f[0] = 0;
f[1] = 1; //2
int i = 2;
while(f[i] <= end){
f[i] = f[i-1] + f[i-2];
print(f);
i++;
print(Array.getInt(f, i));
My understanding is that, as in C, the array elements are pointers (or reference) to the actual values. Is there a way to dereference? How would I assign an element of an array to a single variable to of the same type as the array elements?
Thank you very much for your time!

Hmmmm... it seems I'm missing something. In my previous code,
while(f[i] <= end){doesn't seem to evaluate. also, when I do
j = f;
print(j);
I get 0 even if the element indexed has a non-zero value.

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

How to set the value of an array element (not the complete array) by using a reference?
My situation is that I have an array of clusters on the front panel. Each element is used for a particular test setup, so if the array size is three, it means we have three identical test setups that can be used. The cluster contains two string controls and a button: 'device ID' string, 'start' button and 'status' string.
In order to keep the diagrams simple, I would like to use a reference to the array as input into a subvi. This subvi will then modify a particular element in the array (i.e. set the 'status' string).
The first problem I encounter is that I can not select an array element to write to by using the reference. I have tried setting the 'Selection s
tart[]' and 'Selection size[]' properties and then querying the 'Array element' to get the proper element.
If I do this, the VI always seems to write to the element which the user has selected (i.e. the element that contains the cursor) instead of the one I am trying to select. I also have not found any other possible use for the 'Selection' properties, so I wonder if I am doing something wrong.
Of course I can use the 'value' property to get all elements, and then use the replace array element with an index value, but this defeats the purpose of leaving all other elements untouched.
I had hoped to use this method specifically to avoid overwriting other array elements (such as happens with the replace array element) because the user might be modifying the second array element while I want to modify the first.
My current solution is to split the array into two arrays: one control and one indicator (I guess that's really how it should be done ;-) but I'd still like to know ho
w to change a single element in an array without affecting the others by using a reference in case I can use it elsewhere.> My situation is that I have an array of clusters on the front panel.

It isn't possible to get a reference to a particular element within an
array. There is only one reference to the one control that represents
all elements in the array.
While it may seem better to use references to update
an element within
an array, it shouldn't really be necessary, and it can also lead to
race conditions. If you write to an element that has the
possibility of the user changing, whether you write with a local, a
reference, or any other means, there is a race condition between the
diagram and the user. LV will help with this to a certain extent,
especially for controls that take awhile to edit like ones that use
the keyboard. In these cases, if the user has already started entering
text, it will not be overwritten by the new value unless the key focus
is taken away from the control first. It is similar when moving a slider
or other value changes using the mouse. LV will write to the other values,
but will not rip the slider out of the user's hand.
To completely avoid race conditions, you can split the array into user
fields and indicators that are located underneath them. Or, if some
controls act as both, you can do like Excel. You don't directly type
into the cell. You choose w
hich cell to edit, but you modify another
location. When the edit is completed, it is incorporated into the
display so that it is never lost.

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);

Hi,
I was wondering if I could get some information and opinions about using a type defined array of clusters to hold configuration data. I am creating a program to test multiple DUTs and wanted to have a type defined control for each DUT containing the information needed to create the DAQmx tasks for all of the signals for that DUT. I am wanting to do this so that the data is hard-coded and not in a file that the user could mess up.
The type def controls are then put in a subVI that chooses the appropriate one based on the DUT Type enumeration wired to a case structure.
I am having problems with the type defined control. I am seeing issues when attempting to save a unique configuration to each array element in the array of clusters. Somehow it worked to begin with, but now clicking "Data Operations --> Make Current value default" on individual elements of the cluster or the entire cluster (array element) is not saving the data when I re-open the type def control. What am I doing wrong? Am I trying to do something with arrays of clusters that I should not be doing?
I have attached one of the type defined controls for reference. I tried changing it to Strict to see if that helped, but no luck.
To reproduce, change the resource string for array element 0 and make the new value the default value. Then close the type def, and re-open it. The old value is still present in that element. The VI is saved in LabVIEW 2012.
Solved!
Go to Solution.
Attachments:
CM_AnalogInputs.ctl 11 KBValues of a typedef are not proprigated to instances of the control. THey will pick it up if created AFTER the data values have been changed. THey will not get updated with future changes. You should either create a VI specifically for hardcoding your values or implement a file based initialization. The file based would be much better and more flexible. If you don't want users to modify the data simply encrypt it. There is a noce blowfish library you can download.

Wreck of the Edmund Fitzgerald - Gordon Lightfoot -
I have an existing VI where the original programmer has a 2D array of booleans.
He sets the Array Disabled property to Disabled and Grayed Out.
He is also setting the Array Element.Disabled property to Disabled and Grayed Out.
I am not understanding why it is also necessary to do the latter.Yeah, my quick test shows there is no point in also setting the disabled property of the control in the array.

Change a property of a specifc array element (array of type defs)
If I have an array of elements, and I want to change aproperty of one specific element, at position X, is there a way to do this?
Basically, I have an array of string indicators indicating certain tests attached to certain ports, and I want to change the text to bold on certain indicators, and i want to color certain indicators green or red. Any chance in an array or clusters only?
Thanks Guys.While you can't change the properties for a single array element, there are solutions.
For the background color, you can turn the array element into a cluster of your string (which would be transparent) and a color box which will be the background. You can then change the value of the color box and the color will change.
For the bold text, I think your only option will be to get rid of the string control and make the array element a picture control instead. Using the picture VIs, you can draw a colored rectangle and then place text inside it (and each element can have different text properties). That way, you won't even need the color box.

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.

Sum array elements not working
I am trying to output the average % standard deviation per point for a series of data sets. To do this I want to use the sum array elements function. The program I have written should work I am pretty sure, but when I watch data flow through it, 1000 points get input into the sum function and NaN comes out. What could cause an error like this? I have tried inverting my array, etc. Is there a limit to the number of points the function can take? Or to the precision of the points being input? Thanks, this is driving me crazy!

Average.vi 23 KBAny arithmetic operation on a NaN value is invalid and must result in NaN as
well. You probably need to make sure first that your array doesn't
contain NaN, Inf, and -Inf.

Problem shifting (copying) array elements in a list
I am trying to add points to the beginning of a list. However, I cannot seem to debug the insertBeginning( ) method. I am faced with a problem that overwrites certain array elements. If I can get any help I would greatly appreciate it.
Thanks,
I have included a sample run and some code.
The following url contains both the main and the class files.
http://lbbmx.com/java/
public void appendZ ( Point newPoint ) // used w/ insertBeg method
size++;
cursor=0;
ptlist[cursor]= newPoint;
public void insertBeginning ( Point newPoint ) // Insert begin.
if(this.isEmpty())
{append(newPoint);}
else
cursor=0;
for(int i=size; i>cursor; i--)
ptlist[size]= ptlist[size-1]; //pt[1]=pt[0]
this.appendZ(newPoint);Here is a sample run:
Commands:
+ x y : Append point (x,y) to the end of the list
# x y : Insert point (x,y) at beginning
Q : Quit the test program
Empty list
Command: +1 1
Append (1,1)
size = 1 cursor = 0
0 1 2 3 4 5 6 7
(1,1)
Command: #2 2
Insert (2,2) at beginning
size = 2 cursor = 0
0 1 2 3 4 5 6 7
(2,2) (1,1)
Command: #3 3
Insert (3,3) at beginning
size = 3 cursor = 0
0 1 2 3 4 5 6 7
(3,3) (1,1) (1,1)ptlist[size]= ptlist[size-1];In this situation, size is the variable you are keeping track of how many elements are in your array. This does not change until after you have inserted the new Point. So, regardless of how many times you go around the loop you are simply copy the same value.
"How do I fix it?" I hear you ask.
Well what changes everytime you go around the loop? -
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");

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?

Comparing array elements for equality
Hi
I have written a simple program that works as a lottery number predictor. It works fine except for the fact that sometimes 2 numbers will be the same. Does anyone know of a method that compares an array element to the others to test for equality?ok I've had a go at implementing a solution. I worked it out on paper so I haven't tested it yet in the program. Let me know if you can see any errors that I can't.
boolean numNotSame = true;
int[] lottery = new int[5];
int currentNumber;
start: //label to return to if 2 numbers are the same
while(numNotSame){
for( int j = 0; j < lottery.length; j++){
currentNumber = 1 + randomNumbers.nextInt(34); //get random number
for( int i = 0; i < lottery.length; i++){
if( currentNumber == lottery)
continue start; //if numbers are the same begin again
} //end inner for
lottery[ j ] = currentNumber; //set array element if number not used yet

I am getting an array of 100 elements and i need to delete the the element if it contains 255.And most importantly the next element should be placed in its place.So if i get 30 255s then my output array should get reduced to 70.I tried search 1d array but it is returning only the index of first element containing 255.Please help!!!
Solved!
Go to Solution.Hi muks,
i think i understand what you mean, but i have to create a test array to work with. Attached you can see another way to delete the 255 without using a loop.

How do I programmatically modify array element sizes?
Hi All,
I have a quick question about modifying the size of array elements. Hopefully someone can help, because I am at a dead end!
I am logging some intensities from a Fibre Array using a camera. For calibration of the system, I acquire an image from the camera, click points on the image to divide it into areas of interest. I overlay my image with a grid showing the regions of interst - for example a 4x6 array. I then have to select the fibres - or ROIs - I want to log from.
I have a cluster type-def ( a number and a boolean) to specify the fibre number and to turn logging from that fibre on/off. I overlay an (transparent) array of this typedef over my image to correspond with the regions of interest. So here's my problem - I want to modify the dimensions of the array so each control matches my ROI. I can resize the elements by rightclicking on the elements on the frontpanel, but can't find a way to do it programmatically. The Array Property Node>>Array Element>>Bounds won't 'change to write'...thats the first thing I tried.
Its really only important that the elements align with my ROIs - so programmatically adding in gaps/spacings would also work for me...but again I can't figure out how to do this! I've attached a screenshot of part of my image with array overlaid to show you all exactly what my problem is.
Thanks in advance for you help,
Dave
PS I am running Labview 8.6 without the vision add on.
