Passing a variable's associated number between "for" loops & functions?

Hi,
I seem to be having a problem understanding how variable information can be passed between functions and arrays.
I have variable "grab" set up as a Number.
var grab:Number;
My intent (I'll do my best to explain) is to have a number "attached" to grab when it is first mentioned in this function, itemClick.
These should be all the relevant arrays:
clickItemArray = [scene_Camp.wood, scene_Ax.ax]
itemUsableArray = [wood2, ax2]
sceneGuyArray = [scene_Camp.guy_Camp, scene_Ax.guy_Ax]
function itemClick(event:MouseEvent) {
                for (grab = 0; grab<clickItemArray.length; grab++) {
                        if(clickItemArray[grab].hitTestPoint(mouseX, mouseY, true)) {
                                addEventListener(Event.ENTER_FRAME, itemRemoval);
                                sceneGuyArray[grab].gotoAndPlay("guy_Notice");
                                trace("guy_Notice");
I would like to have the number established with grab (it would either be a 0 or 1, as clickItemArray, sceneGuyArray, and itemUsableArray) be able to be passed into the next relevant function, itemRemoval. I was hoping to use variables so I could use the same function for whatever item was clicked upon. For example, if the clickItemArray item was 1 (the ax), then sceneGuyArray[grab] would = 1, and the right frame would play. That number 1 would be transferred to function itemRemoval, where it would constantly be listening for sceneGuyArray[1] also (where "1" would have been established through the initial "grab" in the first function), and react accordingly.
function itemRemoval(event:Event) {
                for (var grab2:uint = grab; grab2<sceneGuyArray.length; grab2++) {
                    if (sceneGuyArray[grab2].currentLabel == "guy_NoticeDone") {
                        //removeEventListener(Event.ENTER_FRAME, itemRemoval);
                        trace("cheese");
I can't get the trace working, though. I'm sure I'm doing something wrong with "for" loops or the if statement.
Naturally, help would be appreciated.

I do have an unrelated question, if you happen to see this...
Is there a way to "nest" for loops? (maybe there's a better term)
For example, this is part of a function I have
} else if (canClickBoo == false) {
                        //for the click array
                        for (var u:uint=0; u<clickToXArray.length; u++) {
                            //disable the mouse
                            clickToXArray[u].mouseEnabled = false;
                            clickToXArray[u].buttonMode = false;
                        for (var l:uint=0; l<clickFromXArray.length; l++) {
                            clickFromXArray[l].mouseEnabled = false;
                            clickFromXArray[l].buttonMode = false;
                        for (var o:uint=0; o<clickItemArray.length; o++) {
                            //enable items to be clicked
                            clickItemArray[o].mouseEnabled = false;
                            clickItemArray[o].buttonMode = false;
Obviously each "for" loop does the same thing, set the items of each array "false" (make them unclickable if "canClickBoo" is false). In case each array has a different length, though, I can't just use a single "for" loop (afaik).
I'm wondering if, based on what you see (naturally I can post more), I can simplify the code.

Initializing more than one variable of different types in for-loop

I know it is possible to initialize two variables of the same type in a for-loop like this:
for(int i=0, j=0;i<=word.length/2;i++){}
However, I'm trying to initialize two variables of different type in the initialization of for-loop. And the IDE won't let me do it..
for(int i=0, double j=0;i<=word.length/2;i++){}
Is it even possible to do initialize two variables of different type?

Well, just for fun, you can write very generalized for loop. you can do it in a complicated way though.
But, for god sake, why would you do that?
             boolean someboolean = true;
          for(Object i=new Integer(0),j=new Double(1);someboolean;i=(Integer)i+1){
               j =(Double)j + 1;
               if((Double)j>3)
                    someboolean = false;
               System.out.println("i: "+i+" j: "+j+" someboolean:"+someboolean);
          }

For Loop Function is not doing what I am intending to do

In the following example, I am two loops. One upper loop and one inner loop. I have a counter named COPY NUMBER within upper loop. This counter is increasing everytime upper loop and inner loop executes. If the upper loop executes 2 times and inner loop executes 10 times. The counter value has to be 2. But in reality, I am getting the value 20.

Append string to variable in each iteration of for loop in Powershell.

Thanks so much I was able to get it working with the following command!
PowershellGet-Mailbox | where {$_.Name -eq "admin"} | foreach-object {Set-Mailbox -Identity $_.Name -DisplayName "$($_.DisplayName) ABBREVIATION"}
As for their reasoning behind wanting multiple mailboxes, they seem to be wanting to operate as 2 separate entities still. So their old clients still work with them under the old company name and they are paranoid about having names crossover mistakenly. We did try to get them to switch over to 1 mailbox and demonstrated it for them, but this is what they requested.

I have to ask - why keep two separate mailboxes for each user rather than just have one mailbox with multiple addresses?But yes, you can concatenate just like other languages. You have two problems currently -
1. You aren't referencing anything with "$.DisplayName". You need to use "$_.DisplayName" and you need to use it in a Foreach-Object script block.2. You need to pass the concatenated string as a single argument to the -DisplayName parameter. There are several ways to do this but the problem you're having is because there is whitespace in your argument.
PowershellGet-Mailbox | where {$_.Name -eq "admin"} | foreach-object {Set-Mailbox -DisplayName ($_.DisplayName + ' ABBREVIATION')}#ORGet-Mailbox | where {$_.Name -eq "admin"} | foreach-object {Set-Mailbox -DisplayName "$($_.DisplayName)ABBREVIATION"}

If a variable is declared in d for loop, can it be used afterloop exits?

Creating variables using for loop

is there any way in java to create a variable called "xi" using a for loop say:
for (int i =0; i < 1000000;i++){
int xi;
}so I want to create a million of different variable names based on the i... I know this may be a stupid question

I don't think there is a way to do this. More importantly why do you want to do this? If you dynamically generate 1 million variables, then how will the rest of your program refer to them? Maybe what you need is some sort of collection.

Trouble with charAt and nested for loops

Hi,
I have a programming assignment in which my goal is to write a program that reads a social security number written as contiguous digits (eg, 509435456; obtained via JOptionPane); uses charAt to obtain each character; and then prints each digit on a separate line, followed by a colon and the digit printed the number of times equal to its value. Thus the output for 509435456 would be:
5:55555
0:
9:999999999
4:4444
3:333
5:55555
4:4444
5:55555
6:666666
I'm also required to use a char variable for the inner loop control variable, and write the inner for loop as something along the lines of
for(char index = '1'; index <= digit; index++) where digit is the char variable use to store the digit taken from the string.
Here's what I have so far:
import javax.swing.JOptionPane;
public class Prog3a
     public static void main (String [] asd)
     String ssn = JOptionPane.showInputDialog("Que es tu SSN?");
     for (int rows = 0; rows < 9; rows++) //number of rows
               char digit = ssn.charAt(rows) - '0';
               System.out.print(digit + ":");
               for (char index = 0; index < digit; index ++) //how many characters are going to be on each row
                         System.out.print(digit);
          System.out.println("");
}Unfortunately, the char digit = ssn.charAt(rows) - '0'; errors on me, and only works when char is replaced with int. However, digit is no longer a char for the inner loop, and this fails to meet the requirements of the assignment. How can I assign the char without this "loss of precision"?

Original Assignment:
+3a. Write a program that reads a social security number written as contiguous digits (for instance, 509435456), uses the charAt method to obtain each character and then prints each digit on a separate line followed by a colon and the digit printed the number of times equal to its value. Thus the output for 509435456 would be+
+5:55555+
+0:+
+9:999999999+
+4:4444+
+3:333+
+5:55555+
+4:4444+
+5:55555+
+6:666666+
The string should be read using JOptopnPane.
+Use a char variable, e.g., index, for the inner loop control variable and write the inner for loop as for(char index = '1'; index <= digit; index++) where digit is the char variable use to store the digit taken from the string.+
+3b. Write the program so that index, the inner loop index, is an int variable. This means you must convert the character assigned to digit to an int.+

Inconsistent For Loop Write.

I have am trying to take data and append it to a file using a for loop. If you look at the picture you would intuitively think that it would write11 lines onto the file, but it alternates between 9 and 10 lines with no apparent pattern or cause. Can anyobody explain this to me please?

for loop failure.jpg ‏178 KB

You don't need to set the file position. It automatically updates the file position with each write so that you will just keep appending. The other issue is that when you don't use the File Reference Output of the Write to File, the function will close the file for you. So it is likely that LabVIEW tells Windows to close the file, but that takes time. And in that time, you just happen to be able to get more writes in. I would recommend passing the file reference out of the FOR loop (use a shift register along with the reference coming in) and explicitly using Close File after the FOR loop.

So close but need help comparing strings in different subforms with for loop - Livecycle ES

For some reason I was not able to post this in the Livecycle ES forum, even though I've posted there often in the past.
I have created a form that I almost have working and I'm hoping someone can help me.
We have eight billing teams in our company and each team works anywhere from 1 - 4 different clients. The form is used to track, per Billing Rep, the number of items of mail that each billing r5ep works each day. What I'm needing to add at the bottom is a subform that tracks the totals by client. So I'm trying to get the form to loop through all of the existing subforms (and the subforms within them) and compare a cell int he bottom subform to a cell in the other subforms, which are dynamically added, and then total ONLY those items. My script however is not working.
What I have now is:
var repCount = form1.P1._rep.count
var itemCount = form1.P1.rep._ItemSet.count
for (x=0; x<repCount; x++)
     for (i=0; i<itemCount; i++)
          if(clientName.rawValue == P1.rep[x].ItemSet[i].client.rawValue)
          this.rawValue = this.rawValue + P1.rep[x].ItemSet[i].corresp.rawValue;
It seems like this should work but I'm getting the following error:
P1.rep[x] is undefined
So what it looks like is I'm missing is the proper way to reference the objects in these subforms.
The form is here: https://acrobat.com/#d=20gWXZ4sBm4OPV6oO76zSg
If someone could take a look at it I would be so grateful.
Thanks,
Jo

I don't know that anyone else will ever have a similar problem as what I was having, but I figured I would go ahead and post the solution, just in case....
The error I was getting (P1.resolveNode("rep[" + j + "].ItemSet[" + i + "]") is null) was occuring because the variable itemCount needed to be referenced within the repCount For Loop. I also needed to resolve the node for the itemCount, which I wasn't doing.
So...my old code was this:
var repCount = P1._rep.count;
var itemCount = P1.rep._ItemSet.count;   //this part was throwing the error. Needed to use resolveNode...and needed to not declare the variable until inside the first For Loop.
var nTotal = 0;
for (var j=0; j<repCount; j++) {
    for (var i=0; i<itemCount; i++)    {
        if (P1.resolveNode("rep["+ j +"].ItemSet["+ i +"]").client.rawValue == clientName.rawValue) {
            nTotal = nTotal + P1.resolveNode("rep["+ j +"].ItemSet["+ i +"]").corresp.rawValue;
this.rawValue = nTotal;
...which wasn't working because it was trying to reference the count of the ItemSet right up front...but it needed to wait until it got inside the first iteration of the repCount subfields...AND it needed to have resolveNode used.
The corrected code is:
var repCount = P1._rep.count;
this.rawValue = 0;
for (var j=0; j<repCount; j++) {
    var itemCount = P1.resolveNode("rep["+j+"]")._ItemSet.count; //corrected code...node is resolved and variable is declared within the first subform repCount.
    for (var i=0; i<itemCount; i++)    {
        if (P1.resolveNode("rep["+ j +"].ItemSet["+ i +"]").client.rawValue == clientName.rawValue) {
            this.rawValue = this.rawValue + P1.resolveNode("rep["+ j +"].ItemSet["+ i +"]").corresp.rawValue;
...which now works perfectly...and I'm throwing a party to celebrate! LOL

How to create parallel tasks using parallel for loops

Hi,
I am setting up a program that communicates with six logic controllers and has to read the system status every 100 ms. We are using OPC datasockets for this, and they appear a little slow.
I have created a uniform comm. method for all controllers, and now I find myself programming this method six times to communicate with each system. I am wondering if this could be done more elegant using the parallel for loop, in which case I would program an exchange once and then have six workers running simultaneously. Since a picture is more clear that a thousand words, what I am asking is this:
Is it possible to replace something like
by
and have this for loop running these tasks in parallel (on different cores / in different threads)?
I have configured the loop to create 8 instances at compile, so I would have 2 instances surplus available at runtime if I find I need an additional system.
The benefits of the method show in the second picture to me are:
* takes less space
* modifications have to be made only once
* less blocks, wires and stuff makes it more clear what's going on.
* flexibility in the actual number of tasks running (8 instances available at runtime)
* if more tasks are required, I need only to update the maximum number of instances and recompile, i.e. no cutting and pasting required.
Unfortunately, I don't have those system available yet, so there's no way to test this. Yet, I would like to know if the above works as I expect - unfortunately the labview help is not completely clear to me on this.
Best regards,
Frans
Solved!
Go to Solution.

Dear mfletcher,
First of all: thanks for confirming that my intuition was right in this case.
As for your question on the help: below is a copy/paste from the help on the 'configure parallelism dialog box'
Number of generated parallel loop instances—Determines the number of For Loop instances LabVIEW generates at compile time. The Number of generated parallel loop instances should equal the number of logical processors on which you expect the VI to execute. If you plan to distribute the VI to multiple computers, Number of generated parallel loop instances should equal the maximum number of logical processors you expect any of those computers to ever contain. Use the parallel instances terminal on the For Loop to specify how many of the generated instances to use at run time. If you wire a larger number to the parallel instances terminal than you specify in this dialog box, LabVIEW only executes as many loop instances as you specify here.The reason for me doubting if what I programmed would work the way I intended lies in the fact that the help only mentions processors here, which would be interpreted as actual cores. Thus on a dual core machine, the number should be 2.
I think it would be helpful to mention something about threads here, because in some case one would like to have more parallel threads than there are cores in a system.
In mu case I would like to create six threads, which on my dual core processor would be spread over only two cores. Then these six threads run in parallel.I know that in case of heavy math that would not help, but since I am doing communications, which have timeouts and such, and that probably runs smoother in six parallel tasks even though I only have two cores.
Hope this helps in improving the help of the for loop.
Regards,
Frans

Zero iteration for loop

Hi folks,
There's an old behavior that I'm pretty used to, but it still occasionally bites me (usually with references). It happened again today, and it got me to wondering if it's really intended behavior.
If you pass a value into a zero iteration for loop, then send it out the other side, the value exiting the for loop is returned to default, not the value you fed in (see simple.vi, LV7.1).
Any ideas?
Joe Z.
Attachments:
simple.vi ‏11 KB

This is expected behavior...the workaround is to use shift registers to pass the value through instead of tunnels. I believe this is discussed in the LabVIEW Help.

AddChild for loop

I have a MovieClip called item with the same linkage set and my first task is to display 10 of these items on the stage nested inside a movieclip called MainItem. I have dragged MainItem to the stage and have the following for loop:
function displayItems() { for(var i:Number=0; i<10; i++) { var item = new MovieClip(); MainItem.addChild(item).name="item"+i; } }displayItems();
Why is this not working for me?
Any help with this will be great to understand what I'm doing wrong and move me forward in my next task
Thanks
Mark

So just to quickly add, these items now get displayed one after the other so I am trying to add a nice possitioning of 5 items displayed on each row. There seems to be something in the below thats not quite working for me:
var item_xO = 70;
var item_yO = 70;
var item_xS = 15;
var item_yS = 50;
function displayItems()
for (var i:Number=0; i<10; i++)
var item:NewItem= new NewItem();
item.name = "item" + i;
MainItem.addChild(item);
var xPos = 0;
var yPos = 0;
item.x = xPos;
item.y = yPos;
xPos += (item_xO*2 + item_xS);
if (i == 10/1-2) {
xPos = 0;
yPos += (item_yO*2 + item_yS);
displayItems();
Thanks again

How to pass the sequence number of current loop in a for loop in FPGA vi to the host

PCI-7830R
LV 8.2
What I was trying to do is to use multiple DIO to generate pulse at different sequence. Mode one is to automatically sweep from DIO1 to DIO20; mode 2 is several DIOs generate pulse simoutaneously. So I use a case structure to make the selection, in the mean time, I set up two for loop in each case so that I can use multiple pulse generations. For example, in scanning mode, if I set 2 exposures, it sweeps from 1 to 20 then do it again.
Then I need to get the loop sequence number, i of each scenario. So I put an indicator within the first loop, and create a local variable of it and put in the second one. Running the FPGA vi alone, I can see the indicator change in each case from 0 to N-1, N being the for loop time.But in the host vi, I tried to add this indicator as an element in the read/write invoke method, in the debugging mode, I could only see it directly jump to N-1 without all the changes I saw in FPGA vi.
Is it possible to get this number passed correctly from FPGA vi to the host vi? Thanks

Thanks for the reply Jared.
Excuse me if it looks incorrect, but I'm new to FPGA programming, so I would have to look into the FIFO you referred to. I used local variables because for one thing I have several different cases containing for loop in each of them, and I only want one indicator for the "i". If I put the indicator out of any for loop, it's only gonna show the last number which is N-1. For the other thing, it seems like property nodes are not allowed in FPGA vi. And by doing this, I can see the i number changing from 0 to N-1 in each case, well, in FPGA vi's front panel. But while I ran the host vi with everything, the indicator in host vi's front panel only showed the last number N-1. It may be the reason you said, it happened too fast before the indicator in host vi can catch it.
What I want to realize is to group the data I collect in host vi, for example, when I choose multiple exposure in each mode, and the FPGA runs 1 through 20 then do it again, I want the data stored in two groups using the loop sequence number as the seperator in file name. So it goes like 1-1, 2-1.......20-1; then 1-2, 2-2,.....20-2.

Passing a variable's associated number between "for" loops & functions?
