1D Array Of String To For-Loop

Hi fellow engineers,
I'm new to LabVIEW.
I got a question,
If I got a 1D array of string and I want to loop my program to the same number of times (Iteration) in conjunction with the numbers of sub-folders generated by the "list folder" function. How can I do it?
Any help is greatly appreciated.
Solved!

Wire the string array to the border of the for loop. LabVIEW will automatically iterate through each element of the array; you should not wire anything to the N terminal of the for loop. This is the default behavior for arrays entering a loop; if you do not want auto-indexing, right-click on the tunnel (where the array enters the loop) to change the behavior.

I'm having problems manipulating array data within a for loop, and extracting the required sub-arrays generated.

Hi,
I'm using labVIEW V5.1
I'm trying to generate 10 1D arrays, the first array is initialized to all zeroes, then I have set up a for loop which shifts the first element by 1, then a random number is placed into the first element position. I am using a shift register to feed back in the newly generated array into the start of the loop.
By the end of the each loop I want to be able to use the array generated in an algorithm outside the loop. However I only want the Nx1 array that has just been generated.
Unfortunately, I cannot figure out how to resize, reshape or index the output array to do this.
I would like the loop to
give me out a 1D array after each iteration.
Any help would be greatly appreciated.

I hope I've understood your problem.
First your vi was lacking of the sub-vi working as shift register, I've replaced it with the rotate function.
The indexing of your arrays create a 2D array whose rows are your 1D array.To pick only one of them you have to use the index array function and select which one you want.
To use your temporary data in another part of your application you should use a local variable of array2.
I did it in a separated while loop That I syncronized with the for loop using occurrence, in this way the while loop runs each time a new value is inserted in array2 (each loop of the for loop structure).
If you don't need this syncronization just get rid of occurrence functions.
I place a delay in the for loop to show what happens when running.
Hope it was helpful.

How does array obtained in a for loop?

Hi
I went previosly my question as below.
"Firstly thanks for help,
I want to obtain array from the y value calculated in the for loop .at every loop, and in same for loop these different arrays are operated.so with one for loop the calculates are obtained.
Thanks"
Now could you give me one sample program?
Thanks a lot.

LabVIEW ships with a variety of examples. Search through those (hint: look under fundamentals>>arrays) to find what you are looking for.

Array building with a for loop

I am using indexing on the right edge of a For Loop to try to build a larger 2-D array out of smaller 2-D arrays but the output of the tunnel insists on being a 3-D array. I will attach my VI. The sub VIs are not important; the comments in the block diagram should explain the situation sufficiently. Thanks!

Please disregard this request for help. I solved my problem by using 'insert into array' instead of building array.

Arrays dimension changed by "for loop"

When using a two(multi)-dimension array as input to a "for loop", the connection
changes inside the loop to a 1D array automatically. Why?!?
I want to perform the same procedure on each subarray of the basic two-dimension
array, by specifing an index. The second dimension I disable indexing. The
index itself can be the for loop index. The problem is the change in connection
between out and in of the for loop.

The question is that you have indexing enabled in the for
loop entry, and the for loop will convert your 2D array in
the necessary number of 1D arrays to be completed in the
for loop. This is good when you don't know how long the
array is going to be, but if you don't like it, you can
right click on the input tunnel and disable indexing.
Hope this helps.

Why are date and time strings lost when indexing an array in a for loop

Hi,
I have an application where i'm reformatting data from a spreadsheet for graphical display on a LabVIEW dashboard.
the original spreadsheet has date and time values in separate columns, and i'm merging them and converting to a timestamp value. But something's not working. Does anyone know why the string value is lost when the array indexes into this for loop?

Can you attach your VI with some typical values? (e.g. create in indicator on the 2D array, run your VI, then turn the indicator (now containing data) into a diagram constant). Place the FOR loop related code and that diagram constant into a new VI and attach it here.
How many times does the FOR loop run? Could it be that the last element of each 1D array is an empty string? (unless you put a wait inside the FOR loop, you'll never see the other elements in the probe)

Passing an array in a for loop to a procedure

I am trying to pass an array in a cursor for loop to a procedure which performs a table insert using the array's contents. Somehow I am missing something, or it is not possible. The compile error states: PLS-00306: wrong number or types in call to 'insert_address' I checked to be sure I am creating the arrays in both cases from similar data objects. Both address and work_address_table contain the same 4 columns with the same data types.

Can I exit a FOR loop before it has completed its iterations?

Or is there a way to easily slave a while loop to an array input? I essentially need to search an array for a specific entry. Non of the built in VI's will search the array the way I need to do it. I tried wiring the array to a while loop and searching each element, but if the match is never found, the while loop never returns. Is there a setting on a while loop to force it to return if an input array completes?
The For loop will work, but it forces me to step through the entire array each time and I have to play games to ignore values after I have found and set the one I need.
Thanks for any help
Chris

Hello –
I am attaching a very simple example program to show what Alberto and Dennis explained (or at least what I understood their approach would be, please apologize if I misunderstood).
Another option is to use the Search 1D Array function, located in the Functions >> All Functions >> Array subpalette.
Hope this helps.

Not using an array of strings

how do I write a java method without using an array of strings?
for example:
import java.io.File;
public class rename
public static void main(String[] args)
File src = new File(args[0]);
File dst = new File("c:\\temp\\temp.txt");
boolean wasRenamed = src.renameTo(dst);
I don't want to have main use an array of strings but I want rename to work as a class

This is what I changed it to and am getting an -- Exception in thread "main" java.lang.NoSuchMethodError: main
Sorry this is my first java program
import java.io.File;
class App {
     private App() {
          super();
     static final public void main(final String[] args) {
          switch (args.length) {
               case 1:
                    try {
                         Rename rename = new Rename();
                         rename.rename("c:\\felss\\charles.txt.bak"); // see, it's kind of silly to have same names for class and method
                         System.exit(0);
                    catch (Throwable e) {
                         e.printStackTrace();
                         System.exit(1);
                    break;
               default:
                    System.err.println("Usage: java App [new name]");
                    System.exit(1);

     final public void rename(final String newName) {
          File src = new File(newName);

Name of String var passed to a for loop? Array question

I have a series of String variables named q1String where 1 can be replaced by a value from 1 to 17.
So I have a for loop:
for (var i=1;i<18;i++){
var question_caption_mc:Question_caption_mc = new Question_caption_mc;
*question_caption_mc.caption_question_string.text=q+i+String;*
The bold line is causing an error because q is being evaluated separately, i is being evaluated separately, and String is being evaluated separately. I probably should use a different identifier in my variable definition than String but I was wondering how to properly pass the variable name into the for loop so that
"question_caption_mc.caption_question_string.text" will equal the value of the variable q1String through q17String. I know this is simple but I can't seem to figure out how to query this on a web search for a similar thread or solution.
Can anyone help me solve this?
Regards,
-markerline

Okay, I came up with something that produces the start of the result:
for (var i=1;i<18;i++){
var newQStringArray:Array = new Array("q",i,"String");
var question_caption_mc:Question_caption_mc = new Question_caption_mc;
var tempArray=newQStringArray;
var tempString=tempArray.join("");
question_caption_mc.caption_question_string.text=tempString;
trace(tempString);
the trace command comes up with all of the variable names. However I would like
question_caption_mc.caption_question_string.text
to evaluate to the value of tempString or rather q1String through q17String.

Using while loops instead of for loops in arrays?

I am new to java and doing a java tutorial on using arrays and for loops. What im trying to find out is how it is possible to use a while loop instead.
I would be very grateful if anyone can suggest a way of changing my code to use a while loop.
The code I have written is:
public class DetermineGrade
public static void main(String[]args)
final char[] mark = {'A','B' ,'C' ,'D' ,'F' };
char [] grade = new char[5];
int [] Score ={95,35,65,75};
for (int i=0; i<4; i++)
if (Score >= 90)
grade= mark[0] ;
else if (Score >=80)
grade = mark[1] ;
else if (Score >=70)
grade = mark[2] ;
else if (Score >=60)
grade = mark[3];
else grade = mark[4];
for (int i=0; i<4; i++)
System.out.println("grade = " + Score + ", " + grade);
Thankyou LB

Im trying to underdstand the differences in the
different loops. I can grasp the for loop but I dont
see how a while loop works, or how it id different
from the other?
for (j = INIT; j < MAX; j++) {
    // do stuff
}is the same as
j = INIT;
while (j < MAX) {
    // do stuff
    j++;
}Lee

I need help with my for loop in this array

Ok well, I can't get my code to work. Also, please remember that this is just my draft so it isnt pretty. I will fix it up later so please look at it. The thing I want to do is look into the array for a time that matches what the user entered and return the toString() of that one. I know there is something wrong with my for loop but I cant figure how to fix it. please help. here is what i have so far:

Inbound.getTime() is a static method of your Inbound class, that always returns the same value, I presume? As opposed to each of the 25 members of your array in, which have individual values?

Remove text field from Array via for loop

Hi,
i have a problem to remove text fields added via for loop.
That im doing is, via for loop im dynamically creating menu with 10 buttons.
Each button contain, dynamically created, background (shape) and text field.
And everything is fine.
But when im try to remove text fields then i got this error:
- Im using button to remove text fields - lang_btn.addEventListener(MouseEvent.CLICK, clickHandler);

                              else
                                        for (var rNr_eg:Number = 0; rNr_eg < pushEgTFintoArray.length; rNr_eg++)

                                   removeChild(pushEgTFintoArray[rNr_eg]);
                                        //clear the array
                                        pushEgTFintoArray = [];
          btCount++;

it looks like those tf's are children of lmButtonsMCArray[i], not the current scope. use:
if (footer.lang_btn.langState == "EG")
                                        for (var rNr_us:Number = 0; rNr_us < pushUsTFintoArray.length; rNr_us++)
                                                  //remove the text field array from the display
                                    lmButtonsMCArray[rNr_us].removeChild(pushUsTFintoArray[rNr_us]);
                                        //clear the array
                                        pushUsTFintoArray = [];
                              else
                                        for (var rNr_eg:Number = 0; rNr_eg < pushEgTFintoArray.length; rNr_eg++)
                                                  //remove the text field array from the display
                                    lmButtonsMCArray[rNr_eg].removeChild(pushEgTFintoArray[rNr_eg]);
                                        //clear the array

How to output last 4 arrays from a For Loop?

Hi People,
I am almost at the end of my tether. I really hope someone could please help me.
Any input would be welcome. VI attached.
VI explanation:
I initialize an array.
The random number generator simulates my camera input.
Depending on which iteration it is, the data is added into one of four output arrays.
'x-y*floor(x/y)' gives a remainder value of 0, 1, 2 or 3.
'Case Selector' just adds 1 to 'x-y*floor(x/y)' to get case 1, 2, 3 or 4.
Shots 1, 5, 9 etc are added to Array 1 (Case 1).
Shots 2, 6, 10 etc are added to Array 2 (Case 2).
Shots 3, 7, 11 etc are added to Array 3 (Case 3).
Shots 4, 8, 12 etc are added to Array 4 (Case 4).
Averaged Output displays the averaged value i.e. the total value divided by the number of shots saved in that array ('Set (IQ+1)').
My problems are:
1) I would like to output only the last 4 sets of data from the Averaged Output 1, 2, 3 and 4 to 4 different files (i.e. save as .csv what is displayed onscreen in indicators 'Averaged Output 1', 2, 3 and 4 at the end of all iterations.
Where should I place my file save diagram disable so that it does this?
Putting it outside the main For Loop with auto-indexing on gives me one file with all previous data. (This is not feasible as my number of shots should number in the thousands)
Putting it outside the main For Loop with auto-indexing off gives me only the last set of data. (I need the output for 4 Arrays, not just the last run)
Putting it inside the main For Loop (as shown) gives me the same number of files as number of iterations. (Again not feasible due to large number of files that will be generated and slow camera capture)
For the sake of fast camera capture, I would like these 4 files to only output once all the image captures are complete.
2) Would preferably like to name the file once and for the programme to append '(1)', '(2)', '(3)' and '(4)' to filename of the appropriate 'Averaged Output' Arrays but file path controls are another big headache for me.
3) P.s. is initializing one array enough to avoid using Memory Manager? Or should I initialize 4 arrays?
I am using Labview 2010.
Thanks so much,
Jaslyn

Thanks so much Lennard!!
Hi JKSH,
I've been busy trying to complete the dang code, but for completeness so that other users can learn too, I shall answer your queries. Thanks for looking in.
First, what do you mean by "add"? Your code in your case strcuture sums your input values, so your array size doesn't change. However, you also said "Putting it outside the main For Loop with auto-indexing on gives me one file with all previous data. (This is not feasible as my number of shots should number in the thousands)" -- it sounds like you are expecting an array with thousands of elements. So, what should "Output Array N" look like?
Ans: Output Array N should be a 4x4 array of the summation of all the numbers generated during every 4th iteration.
i.e. if random number 1=1, random number 2=2, etc, And 'No of iterations' is 12,
Output Array 1 should be 1+5+9:
15 15 15 15
15 15 15 15
15 15 15 15
15 15 15 15
(Note: Most of your arrays are 4x4, but in Case #2 you created 128x128. I prersume this is a typo?)
Ans: Kind of, I'm using a 4x4 array of randomly generated numbers as an example but my actual data will be the 128x128 pixel output of a camera. And during actual experimentation, 'No of Iterations' will number in the thousands.
Second, why do you add your "simulated camera input" to the "Initialized Array"? You can add it direcly to the previous output inside your case structure.
Ans: See answer to question 3
Third, have a look at shift registers: http://www.ni.com/gettingstarted/labviewbasics/shiftregisters.htm. Use them instead of Feedback Nodes to make your code tidier.
Ans: I did try.. But I can't seem to add shift registers to the case structure, only the for loops outside. Are you sure it can be done..?

You will need to call "Write to Text File.vi" 4 times to write 4 files. So, you should finish your loop, then call this VI 4 times.
Ans: How do I get it to extract the data from each of the 4 cases in my case structure?

You can create strings first, then convert them into paths: http://zone.ni.com/reference/en-XX/help/371361G-01/glang/string_to_path/

I'm not sure what you're asking; can you please clarify what you mean by "avoid using Memory Manager"? But anyway, you've actually initialized FIVE arrays: 1 outside the loop, and 1 inside each case.
I've read that to avoid fluctuations in memory usage, it is a good idea to initialize arrays to their expected size before the start of data collection. That was just what I was trying to do.

String of letters to 1-D Array of strings for spreadsheet

What I would like to do is be able to take this string as it is the A's and B's that are being generated as the program runs,
I would like to take this string and get it into file in delimited tabs just as the numbers are. If there is a created 1-D array of
strings that works, but that is controlled on the front panel, I would like to create this from data that is comming in. In other words
I am stuck on how to create a 1-D array of Sting from the string value comming in. I want to do this so that I can get all the different
values A's or B's into the different tab fields. As it is they are comming all up in the first column and not "tabbing" Please see the
attached file in the rows 5 an
d 7.
Thanks,
Brian

You need to convert your string to contain single tabs as separator. The problem is that your string is "dirty", i.e. it contains a variable amount of spaces to seperate the items. If you strictly had single space separators, you could just replace all spaces with tabs.
"Scan string for tokens" by default does not allow empty tokens, thus takes care of the multiple spaces.
The attached simplified code assumes a fixed number of items (12), if this is a variable, you need to use a while loop and sense the end of the input string. Let me know if this is clear.
