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.
Best Regards,

You can access the name of an object by using ActiveX to get to the step's Property Object. Once there, you can use a property node for the name and change it to write.
Let me know if you need more information about this.

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?
public class Franchise {
private Franchise[] franchise;

Sure,
The reason what you're doing doesn't work is that anything inside of
"#{}" is for deferred evaluation and is evaluated by the JSF engine,
while scriptlets are evaluated by the JSP engine. I have modified the
guessNumber demo included in the 1.0 release to do what you're trying to
do.

What I'm doing here is to store the variable into request scope, then I
can access it using the implicit object requestScope.
This approach should give you what you need.
Ed (EG Member)Thank you for your answer!
but I still have question.
I will output a array,but the size of array is dynamic,
and the size is passed by the SearchItemBean.
How can I control the i to increase to the specify number?
how can I pass the size parameter into the <c:set>?
How can I use a paratemer passed by size and control the "i" to increase to it?
thanks! -
Accessing a user array elements in Captivate 6
Hi guys I have a piece of code that's not working I was hoping someone had any clue as to why, I've wasted too many hours trying to figure this out. Here's the code, explanation below.
var objCP = document.Captivate;
objCP.cpEISetValue("m_VarHandle.questionList", new Array(7));
objCP.cpEISetValue("m_VarHandle.questionList[0]", 1);
objCP.cpEISetValue("m_VarHandle.questionList[1]", 2);
objCP.cpEISetValue("m_VarHandle.questionList[2]", 1);
objCP.cpEISetValue("m_VarHandle.questionList[3]", 2);
objCP.cpEISetValue("m_VarHandle.questionList[4]", 1);
objCP.cpEISetValue("m_VarHandle.questionList[5]", 2);
var cat1Len = 0;
var cat2Len = 0;
for (var i=0;i<objCP.cpEIGetValue("m_VarHandle.questionList.length");i++){
var value = objCP.cpEIGetValue("m_VarHandle.questionList[i]");
if (value == 1)
{cat1Len++;}
if (value) == 2)
{cat2Len++;}
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?
Thanks for any help!should be:
var objCP = document.Captivate;

i is only defined local to the javascript eval, not a global variable. You have to pass the value, not the name of the index...

How can I remove only the middle elements from a 2-D array?
Hello all!
We have had an issue at my work where some of our graphs featuring a Gaussian curve have an unusual rectangular distortion in the middle of the curve (sorry that I have no image to show you, the error is before my time at the company, and I've been asked to find a solution before it happens again). Basically, what should be a Gaussian curve is leveling off briefly and looking like a rounded square wave. We know what causes the distortion, so I only wish to remove the middle part, giving it the appearance of a Gaussian. It's odd, but it actually offers a good approximation of what we want. The graph is made from a 2-D array of Double values, and we can estimate the size of the leveled-area, so I figured that removing the middle elements from the graph would accomplish this. Does anybody know a way I can accomplish this?

Dynamically create empty mcs and asign elements from array and loadmovie
I'm creating an educational game for my school students.
A little boy is flying through the city when he encounters objects flying from left to right.
He hears a SOUND eg: Dog - he must go and click the dog image with the flying cursor. There are at least 5 DIFFERENT objects that should be flying on the screen. There could be various of them at any one time.
I have the roots of the images in an xml file. And the actual swf are in a file called IMAGE and the sounds in SOUND.
My problem is that most tutorials I see use the attachmovie method but I don't want to put all the swf's in the library as there are hundreds.
I have to use the loadmovie method.
I take it I have to loop through the array and assign each element to an empty movieclip which in turn is in the loop so you get 5 empty clips - I will use i (index). It doesn't seem to be working. I shall keep trying and post back here if I get any luck but I'm running out of ideas.
Then the objects have to float across the screen. Don't know whether to use tween object or onEnterFrame handler or other. AND someone has mentioned using setinterval to "spit out" the objects.
BUT if I have five flying across the screen I'm left without clips to stick in any more.
Oh my head hurts but I will keep going.
CHEERS if any help is around. This should be quite a standard thng for game developpers. Code at the moment
function loadEnemies():Void {
enemy_xml = new XML();
enemy_xml.ignoreWhite = true;
enemy_xml.onLoad = function(success:Boolean) {
if (success) {
_root.parseEnemyXML();
//enemy_xml.load("level_"+level+".xml");
enemy_xml.load("data/animal_catch.xml");
function parseEnemyXML():Void {
rows = enemy_xml.firstChild.childNodes.length;
for (var i:Number = 0; i<rows; i++) {
var row_string:String = String(enemy_xml.firstChild.childNodes[i].firstChild.firstChild);
_root["row_"+i+"_array"] = row_string; //MAIN ARRAY holds an array images/dog_a.swf/ images/cat_a.swf etc... all five
_root.createEmptyMovieClip("enemyObjects", 1);
enemyObjects.createEmptyMovieClip("holder_"+i, i);
_root["object"+i] = new Sound(enemyObjects["holder_"+i]);
trace(row_string);
loadMovie["row_"+i+"_array"], ["holder_"+i]
if (level == 1) {
alerts_mc.play();
} else {
currRow = 0;
rowCounter = 0;
OK got to about here BUT
a. I started to get confused around the createEmptyMovieClip part
b. I KNOW I shouldn't have Sound(enemyObjetcs etc... BUT I copied the code from a tutorial and I don't know what to replace it with.
I'm close but I need a little polishing.It doesn't do you much good to work with borrowed code that you do not understand. Your best bet will be to start small, creating one functional piece of the puzzle at a time, and work your way up. Start with making sure you are loading and parsing the xml properly, then set about loading the external content, then see about making that content move around, etc...
In the code you show, your loadMovie line of code does not resemble anything I have seen before, looking more like (but not quite like) a multi-dimensional array element than a loadMovie() function call. If you find you need to have control of the items as soon as they load, then you should consider using MovieClipLoader.loadClip instead of loadMovie. The MovieClipLoader class provides features, such as to be able to determine when items have fully loaded. -
How to create an array in one field and have another field display certain elements from that array?
I am making a form in Acrobat XI pro.
In one text field, I created an array of several elements. I want other text fields to display certain elements from that array. For instance, one field should display the 3rd element, another field should display the 13th element, etc.
The Javascript for making the array is very long, and so I don't want to have to re-calculate the array every single time (in order to reduce rendering time when I open the form on an iPad). This is why I'd like to only have to create the array once, and simply refer to it throughout the form.What code are you using to update the array currently? Are you completely rebuiding it when an element changes, or just changing specific elements for certain fields? I'm still not sure what exactly you are trying to do, but something like this in a document level script will create your array:
var myArray;
// Call 'updateArray' to initialize array
updateArray();
function updateArray() {
// Code here to create/update array
myArray = new Array();
myArray[0] = "Value 1";
myArray[1] = "Value 2";
myArray[2] = "Value 3";
Then, for each field that needs to update this array, you can add a call to 'updateArray()' in the appropriate event. This will rebuild the array completely; if you just want to update specific elements, then you can access them directly. -
Problems selecting elements from arrays
I'm having difficulty selecting indexed elements from a array of nodes. I have seen this issues discussed in a number of threads but none address the specific issue which I have encountered.
Previously in version 10.1.2 I constructed a XPath query and then used the BPEL getVariableData function to obtain the element I was after but this doesn't appear to be supported the same way in 10.1.3.1.
I'm using the following expression
bpws:getVariableData('VariableDBResult',bpws:getVariableData('xpath'))
and when I try to compile I get the following error
Error(243):
[Error ORABPEL-10085]: invalid argument
[Description]: in line 243 of "C:\....", the second argument "bpws:getVariableData("xpath")" for getVariableData is not a literal expression.
[Potential fix]: Please correct the second argument, you might need to escape using single quote or " to make it literal.
I used the same code in 10.1.2 and it compiled fine.
For reference the XPath is formed as follows
concat('/ns3:Result/ns3:t/ns3:c/ns3:e[',bpws:getVariableData('loop'),']')
But the error occurs at compile time not run time so I suspect the way the xpath is formed would not affect the compile
I'm suspecting the problem has something to do with the fact that I'm using the function without the optional "pat name" the variable "VariableDBResult" is defined by a schema not a WSDL message type. I have compiled the Array sample 112 which used a part name and it works but in my case without the part name it fails.
I attempted to cast the expression to a string and use a string variable, all to no avail.
Any help or suggestions will be greatly appreciated.
Regards
GraemeHas anybody got around this issue...I searched the forums but allI could get it unresolved threads pointing to this problem

Deleting elements from Arrays.
Hello,
I have to be able in this latest exercise to delete an element from an Array. I was wondering if you could give me code examples on how to do this. I am pretty sure that you have to read through the array and return "null" when you hit the element that you want to delete in the array.
Thank you.Look through the forum. There are at least two other threads open with people asking the same question.

How do I access array elements in one method from another method?
Hi all!
How do I access the array's elements from another method so that method 2 can have access to method 1's array elements? Thanks for any help!
I am trying to create a simply program that will use a method to create an array and a SEPARATE method that will sort the array's elements (without using java's built in array features). I can create the program by simply having one method and sorting the array within that same method, BUT I want to sort the array from another method.
Here's my code so far:
public class ArraySort {
public static void createArray(int size){

}Thanks again!
- JohnnyThanks for the help all! I ve managed to get the program working, using java's built in array sort, but when i try to call on the array sort method from WITHIN my main method, nothing happens!
Can somebody please tell me why I am not able to call on the sort method from within my main class???? Thanks!
public class ArraySort {
public void createArray(double[] arrayName, int size){
double myArray[] = new double[size]; //create new array
for(int j=0; j < myArray.length; j++)
myArray[j] = (200.0 * Math.random() + 1.0); //populate array with
} //random Numbers
sortArray(myArray);
} //Sort array(if I delete this & try to use it in Main method --> doesn't work???
public void sortArray(double[] arrayName){
DecimalFormat time = new DecimalFormat("0.00");
Arrays.sort(arrayName); //sort array using Java's built in array method
for(int i = 0; i <arrayName.length; i++)
System.out.println(time.format(arrayName)); //print arary elements
public static void main(String[] args) {
ArraySort newArray = new ArraySort(); //create a new instance
double myArray[] = new double[0]; //create a new double array
newArray.createArray(myArray,4); //build the array of indicated size
//newArray.sortArray(myArray); //This will not work???? WHY?????// -
Plotting elements from an array in waveform chart
Hi all,
I am trying to plot a real time data by extracting single element from an array.
Problem is that, at some frequencies waveform chart plot perfect while at other frequencies it plots like a undersampled signals.
Any suggestions?

wfm.vi 133 KBThe timing information comes from the data acquisition process, not the display. You should be able to get equally good display of timing information on a chart or a graph.
How many samples do you read at a time? How do you define "realtime"? Anything plotted on a graph or chart for the use of a human operator does not need to be updated more than about 10 times per second because the eye/mind system works at about that time scale. For humans a real time grahical update rate of 2 to 10 Hz is adequate. Then you will have 256 to ~51 new samples at each update.
Another issue is that both your graph and your plot have plot areas which are less than 200 pixels wide. If you supply more than [plot width] pixels to a graph or chart, LabVIEW will reduce the data to determine which pixels to plot. So your graph with 1000 X-axis values has that reduced to the 184 pixels across the width of the graph. So, regardless of the precision of the data, the "precision" of the display is limited to the number of pixels.

I have tried intializing an array and replacing elements by specifying a particular row, and column, but in the end I get an array with only one element replaced, and I suspect that it is because as the for loops are running through their iterations each time the array is re-initializing. I have a simple vi that I will post below, it is not the exact situation that I have but is a good place for me to get some understanding. I have the row and column indexes being driven by the inner and outer loop iterations, which gives me the pattern I need. I am using the inner iterations as array elements. How do I set this up so that it works and d
oes keep re-initializing my array.

Untitled.vi 26 KBI have fixed a number of things in your vi.
You were right in thinking that the array was continuously re-initialized. To avoid this, use a shift register (right-click the loop border), which will pass the updated array into the next iteration.

Not getting all results in Array Populated from Query
When running this it is only giving me the last value of my query in the array. Any thoughts on why this is happening? I appreciate any assistance. Thank you
<cfset result = arrayNew(1) />
<cfset ArrayMedSchools = structNew() />
<cfloop query="GetMedSchool" >
<cfoutput>
<cfset ArrayMedSchools.name = Institution />
<cfset ArrayMedSchools.id = InstitutionID />
<cfset arrayAppend(result,ArrayMedSChools) />
</cfoutput>
</cfloop>
<cfset ArrayMedSchools = structNew()/>
<cfdump var="#GetMedSchool#" label="Original Query">
<cfdump var="#result#" label="resulting array">So your query has X rows. Does your array have the values for the last row in your query, duplicated X times? Or does it just have one element, with the values from the last row in the query?
One thing you might want to try is resetting the structure within your query loop:
<cfset result = arrayNew(1)>
<cfset ArrayMedSchools = structNew()>
<cfloop query="GetMedSchool">
<cfset ArrayMedSchools = structNew()>
<cfset ArrayMedSchools.name = GetMedSchool.Institution>
<cfset ArrayMedSchools.id = GetMedSchool.InstitutionID>
<cfset arrayAppend(result, ArrayMedSchools)>
</cfloop>
<cfdump var="#GetMedSchool#" label="Original Query">
<cfdump var="#result#" label="resulting array">
Also note that you don't need to use <cfoutput> within your loop there. -
Is there a way to select a certain box of elements from a csv file and read that into LabVIEW?
Hello all, I was wondering if there was a way to select only a certain "box" of elements from a .csv file in LabVIEW? I have LabVIEW 2011 and my main goal is to take two arrays and graph them against each other. I can import the .csv file just fine and separate each row and each column to be its own, but say I have an 8X8 but want to graph the middle 4X5 or something like that. Is there any way to extract an array without starting at the beginning and without ending at the end? Thank you in advance.
Solved!
Go to Solution.Hi Szklanam,
as a CSV file is just a TXT file with a different suffix you can read a certain number of lines of that file. So you can limit the number of rows in your resultung array. To limit the number of columns you still have to use ArraySubset, so maybe it's a lot easier to read the full CSV file and pick the interesting spots with ArraySubset...
