Read part of an array element

Hello All.
As indicated in the title, I am trying to read part of an array element.
What I'm doing is reading values from a LeCroy scope using a "write" than "read" I have returned the read values into an array but the issue is the scope returns a value "1, 52.33E-3"
I simply want the element to be 52.33 that way I can use that for other calculations.
For example my array is.
"1, 34.334E-3"
"1, 53.343E-3"
"1, 143.232E-"
And I want it to be
34.334
53.343
143.232
Thanks!

Another option is to use Spreadsheet String to Array and use the comma as the delimiter. It can actually change your string into an array of numbers. Then you just index out the number you want.

I do not use ISE much myself, but it seems to me that others have reported problems here that resulted from variables from an earlier run remaining in existence when a script is re-run when ISE was used.
Of course, that would appear to be only part of your problem, as, ideally, the script should be able to find all empty folders when run only once.
One thing you could do that might help would be to display all variables before the first run, between the two runs, and after the second run. When you see what values are contained after the first run, this might give a clue as to why or how the script
seems to manage to get farther on the second try.
This sounds like it may possibly be a one-off situation. Although "F" precedes "G" alphabetically, the file/folder system is not necessarily maintained in alphabetical order. If the "G" folders are processed before the "F" folders, then it seems likely that
F4 is the very last folder processed. Perhaps it is being processed correctly, but the results are just not being properly recorded.
Let us know how you get along with this.

Change array element "initialized" property

I'm a newcomer here. And it is a simple question.
The aim of this part is to save the array data.
You can see that if the array element is uninitialized, it won't be saved to spreadsheet, which saves space in the disk. So can I change the "initialized" property of this array element back to unitialized?
Thanks
Solved!
Go to Solution.

You can "right-click the element...data operations...delete element".
(This has nothing to do with "uninitialized". The size of the array is indicated by the bright elements, the dull elements are outside the valid range, which has nothing to do with the size of the container. Your first array has two elements and your second array has three elements.)

How to edit items of a combo box that is part of an array of clusters

Hi,
In the attached vi, I have an array of clusters, and each cluster contain two combo boxes. How do I edit the items in Combo Box 1 for all elements of the array? (All Combo Box 1 elements shall include the same items.)
For illustration, I also included the trivila case, i.e., editing the items in a separate combo box that is is not part of an array of clusters (Combo Box 3). Please advise. Thanks.

Without loops how can i read data from associative Array??

Hi all,
I am facing scenario like...
i need to read data from associative array without using loops is it possible,
CREATE OR REPLACE PACKAGE BODY test_pkg IS
    TYPE t1 IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
   -- in array we can expect more than one row or sometimes no data also.
FUNCTION test1(vt1 T1 DEFAULT CAST(NULL AS t1)) RETURN NUMBER IS
BEGIN
    -- basically in array we'll get data of column2
    -- this loop should satisfies table1.colum2 = nvl(NULL, table2.colum2 )if array is null.
    -- if array is not null then only compare with array values
    FOR i IN (SELECT t1.colum1,t1.column2
                     FROM table1 t1, table1 t2
                          WHERE t1.colum1 = t2.column1
                            AND t1.colum2 = nvl(vt1, t2.colum2)
      LOOP
        generateTEXT(i.colum1, i.colum2);
     END LOOP;
END test1;
END test_pkg;
in table1 we have date like...
colum1          column2
Jan                  1
Feb                  2
Mar                  3
if i call select test_pkg.test1(1) from dual then output should
be Jan..
and
select test_pkg.test1(null) from dual then it should display all elements from table1.
Jan                  1
Feb                  2

Thanks for your quick replay..

i need to read data from associative array without using loops is it possible,
No - you would need to create a SQL type and then use the TABLE operator to unnest the collection.
create or replace TYPE my_nums IS TABLE OF INTEGER;
DECLARE
-- TYPE my_nums IS TABLE OF PLS_INTEGER INDEX BY PLS_INTEGER;
v_nums my_nums := my_nums(1, 2, 3);
v_total number;
BEGIN
select sum(column_value) into v_total from table(v_nums);
DBMS_OUTPUT.PUT_LINE
    ('Sum of the numbers is ' || TO_CHAR(v_total));
END;
Sum of the numbers is 6

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,

Allocate array elements one at a time?

Is there a way to allocate array elements one at a time?
The following code will crash because the minimumLogIndices array is not allocated.
// get all indices where cArray[i] > minimumLog
int[] minimumLogIndices = null;
for (int i=0; i < columns; i++)
if ((cArray[i] > minimumLog))
minimumLogIndices[i] = i;
}I would like a statement like:
minimumLogIndices[i] = new(i);but this is not allowed, of course.
If I use ArrayList, then the elements can be added one at a time, but I cannot use int.
null

int[] minimumLogIndices = new int[columns];As described here:
http://java.sun.com/docs/books/tutorial/java/nutsandbolts/arrays.html
[Edit] The array will, however, have "holes" in it when cArray[i] <= minimumLog, but that's inevitable if you are using an array.

Problem in assigning value to an array element

hi all
in the following prog i am not able to assign the value to the array element
i am not getting why it is giving me error
//my program is as follows
public class ArrayTest
     static int [] intArray = new int[5];
     static int [] intArray1 = new int[1];
     intArray1[0] = 5; // this line gives error
     static char [] charArray = new char[5];
     public static void main(String args[])
          System.out.println(charArray);
          intArray1 = intArray;
}thanx in advance as usual

The problem is that you try to execute code outside a method. This can be only done in form of a variable declaration or as a static initilization block which will be executed once when the class is loaded:public class ArrayTest
     static int [] intArray = new int[5];
     static int [] intArray1 = new int[1];
     static char [] charArray = new char[5];
     static {
          intArray[0] = 5;
     public static void main(String args[])
          System.out.println(charArray);
          intArray1 = intArray;

How to set an array element in an object type of array??

Hi,
I have set attribute as follow:
Color[] colors;
Color[] colors = new Color[20];
colors[0] = "Red";
colors[1] = "blue";I can't compile this code. It said:
"Incompatible type -found java.lang.String but expected Colors
Could you tell me how to set an array elements when the array type is an object?

in your case, the array shouldn't be Color[] but String[] since you re intending to put strings into it
by the way, you could also use a hashmap to map a string to a color:
HashMap<String, Color> hm = new HashMap<String, Color>();
hm.put("Red", Color.RED);
hm.put("Blue", Color.BLUE);
etc.

"In initializer for 'mxmlContent', type Object is not assignable to target Array element type..."

Hi all,
So I've have built an application on flash builder 4.5 using Christophe Coenraets' tutorial "Building an EmployeeDirectory" (http://www.adobe.com/devnet/flex/articles/employee-directory-android-flex.html#articlecont entAdobe_numberedheader).
I'm getting this error message "In initializer for 'mxmlContent', type Object is not assignable to target Array element type mx.core.IVisualElement." and then the debugger highlights my code this line of my code "</s:List>" in my EmployeeDetails.mxml file. This started after I coded Part 5, Step 2 "Integrating with the Device Capabilities: Triggering the Actions". The rest of the code debugged fine.
I think it relates to Christophe's note "Note: Make sure you import spark.events.IndexChangeEvent (and not mx.events.IndexChangedEvent) for this code to compile.". I don't know where to place this
" import spark.events.IndexChangeEvent;" line of code.
Any help? Tks in advance..
Any help would be greatly appreciated. Thanks

You have a DataGrid directly inside a State element. Perhaps wrap it in an AddChild element?

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 you

How does the "Read TDMS" function work when reading part of a data file?

Hi everyone,
I have stored some rather large .lvm files that causing me a a big headache when trying to read/analyse the data.... As a work around I first convereted these files to .tdms.... Now the files are much smaller (50%) and can be load/plot within a couple of seconds rather than 10's of seconds.
Specifically, the files include 7 channels of data that were sampled at 2kHz for about 8-9 mins..... So, each file contains about 700,000 data points or elements.... I am using a producer/consumer architechure to read/plot all the data, then using cursors to identify a data subset, which is send via a queue to the consumer where analysis occurs.... Given the size of the files, when subset is quite large I get "Out of Memory" errors and LabVIEW crashes.
What I am thinking is that I can down-sample or decimate the data in the producer back to 1kHz (I need to ms resolution so I can see the spikes and can appropriately selected the subset) then index back into the original tdms file to send the undeciated data to the consumer.
With the "Read TDMS" function, the help states:
COUNT: Specifies the maximum number of data elements to read from the .tdms file for each channel. The default is –1.
OFFSET: Specifies the number of data elements into the .tdms file at which the function begins analyzing the .tdms file. The default is 0.
I am confused by the term "elements". Does this mean actual "data points" as in elements within the 2D array? Or bytes? I am hoping array elements... Would this then mean that given my 7 channels of data, each element value that is a multiple of 7 would index into a new line of data? I also assume this index is zero based... So with no offset, a count value of 0 would return all the data elements at time 0.0000s for all channels (regardless differences in the precision of each channel, unlike bytes), a value of 7 would return all the data elements at time 0.0005s, a value of 14 would return all the data elements at time 0.0010s, etc etc..
Also, if anyone has any example code for indexing into a file using this method they could shareI would be very appreciative... I would assume a for loop could also be used to read the data subset into the consumer in smaller chunks to reduce the memory load?
Many thanks,
Jack

You should have a different channel in the TDMS file. So you are reading X elements from a channel starting at element Y. Yes, those are elements in the array, not Bytes. NI did a good job of making the API easy to use.

I was wondering if it's possible to change which element of an array control is displayed on the front panel from within the program.
Here's why I want to do it: I have an array of clusters, each of which contains a set of controls. The controls in each cluster specify a bunch of different parameters for a few different instruments that are being controlled by Labview. The user changes all the values on the front panel before the program starts, then the program steps through the array elements one by one. I'd like to be able to change the array's display so that the user can know which set of parameters is active (and thus what is currently in force) while the program is going -- otherwise the element that is displayed is just wherever the user left it last.
Thanks in advance for any help.
