Include FOR LOOP inside a parameter

Hi Programmers,
I have this portion of code where I want it to display list of all customers inside the email being sent to a sales manager. However, no result generated.
message:='Sir/Madam,'||CHR(10)||CHR(10)||'Display List of Customers '||CHR(10)||CHR(10)||
lpad('List of Customers ', 50)||CHR(10)||CHR(10)||
FOR customer_rec in customer_cur
LOOP
lpad('Customer Name : ', 50)||customer_rec.first_name||' '||customer_rec.last_name||CHR(10)||
lpad('Customer Office Address : ', 50)||customer_rec.address||CHR(10)||
lpad('Postcode : ', 50)||customer_rec.postcode||CHR(10)||
lpad('State : ', 50)||customer_rec.state||||CHR(10)||CHR(10)||
END LOOP;
'End of list';
Please help..

I don't understand why you created 3 duplicated thread? And on top of that you didn't even bother to format the code?
It's lack of respect i would say .....

Hi fais,
Following through with what JB suggested. The steps involved in replacing the inner for loop with a while loop are outlined below.
You can replace the inner for loop with a while by doing the following.
1) Right-click of the for loop and select "Repalce" then navigate to the "while loop".
2) Make sure the tunnels you where indexing on with the for loop are still indexing.
3) Drop an "array size" node on your diagram. Wire the array that determines the number of iterations your for loop executes into this "array size".
4) Wire the output of the array size into the new while loop.
5) Set the condition terminal to "stop if true".
6)Drop an "OR" gate inside the while loop and wire its output to the while loops condition terminal.
7) C
reate a local of the boolean "stop" button, and wire it into one of the inputs of your OR gate. This will allow you to stop the inner loop.
8) Drop a "less than" node inside the inner while loop.
9) Wire your iteration count into the bottom input of the "less than".
10) Wire the count (see step 4 above) into the top input of the less than. This will stop the inner loop when ever the inner loop has processed the last element of your array.
Provided I have not mixed up my tops and bottoms this should accomplish the replacement.
I will let others explain how to takle this task using the "case solution".

How do I break a for loop (inside) and a while loop (outside) at the same time by a control button

I have a while loop (outside) and a for loop (inside) and a control button within the for loop. I want to stop the program by click the botton without finishing the for loop. How can I do that?
Thank you in advance.

For loop inside a while loop, what order is that in big o??

If say I have a for loop inside a while loop, then is that suppose to be in the order of O(n^2) right?? Is there any possibilities to change this into the order of O(n)??

the other size and the temp size is abstact, which can be defined. This is actually for my union method, my teacher asks me to write this method using the order of O(n) which I think it is not possible. What do you guys think??
Below is the code I have made:
public Set<E> union(Set<E> other) {
          int count = 0;
          Iterator<E> iterator1 = other.iterator();
          while (iterator1.hasNext())
               count++;
          Object[] temp = new Object [data.length+count];
          n = data.length+count;
          for (int i = 0; i<count; i++)
               temp[i] = data;
          for (int j = count; j<temp.length; j++)
               temp[j] = iterator1.next();
          data = temp;
          return null;
but it still has same elements on it and I am thinking of a way on how to remove those same elements

Simple example - Break FOR loop inside an event structure based on Front panel event change.

I am running a for loop inside a state machine architecture that contains a FOR loop. How can I break this For loop based on Event change in front panel ??

Okay. Accpeting that the design is not favorable and not advantageous when my program expands. I have begin to follow producer/consumer programming architecture.
Please find the attached program which is a simple producer consumer with event structure. I wonder how could I stop looping around the producer and consumer loops over and over again. I am pretty sure that this ENQUEUE ELEMENT loops back to the consumer loop and starts from begining.
I hope my first program in PC architecture with State machine and Event structure is correct.

You're implementing a For loop inside an event structure? (I don't know of any event "node" in which you can run a For loop)
If so, that's a bad idea because LabVIEW won't be able to process any events while waiting for your For loop to get done, which might be why its crashing.
There are tricks to accomplishing what you're trying to do without putting any for loops inside event structure. See what I have attached and if it helps. "N" is number of times you run your For loop, timeout is whatever delay you want in each loop. This can be done in many ways without adding delays in events, another way could be to fire a separate subVI using Asynchronous call (without waiting for the VI to finish) during those delays, just make sure that such subVI finishes processing within your allocated time (that's how I'd ideally implement things). That method is better because you're doing minimal work inside events structure while using wait period wisely in a separate/parallel process.
I hope that I understood you correctly and did not go off on a tangent.

One thought I have is that I think you want those feedback nodes reinitializing for each iteration of the outter loop. Personally, I would change them to be shift registers (it would clean up your diagram a little bit).

Getting a for loop inside a while loop

I've been having problems with the code below. I'm trying to get the 'while' loop to work so that the program will continue to run after a user types in a sentence. This is supposed to print out how many times a letter has been typed when a sentence has been put in, but it's not working right. It just keeps adding the first sentences numbers together even when a new sentence is typed out. I don't know what I'm doing wrong with this 'while' loop.
import java.util.Scanner;
import java.util.*;
public class Count
public static void main (String[] args)
String phrase; // a string of characters
int countBlank; // the number of blanks (spaces) in the phrase
int length; // the length of the phrase
int countA = 0; // the number of a's in the phrase
int countT = 0; // the number of t's in the phrase
int countE = 0;
int countS = 0;
char ch; // an individual character in the string
Scanner scan = new Scanner(System.in);
// Print a program header
System.out.println ();
System.out.println ("Character Counter");
System.out.println ();
// Read in a string and find its length
System.out.println ("Enter a sentence or phrase ('quit' to quit): ");
phrase = scan.nextLine();
length = phrase.length();
// Initialize counts
countBlank = 0;
// a while loop to allow user to keep entering phrases
   while (true)
   String line=scan.nextLine();
          System.out.println("Type quit to quit or enter a new phrase.");
     if(line.equals("quit"))
break;
// a for loop to go through the string character by character
// and count the blank spaces
for(int i = 0; i < phrase.length(); i++)
ch = phrase.charAt(i);
switch (ch)
case ' ': countBlank++;
break;
case 'a':
case 'A': countA++;
break;
case 't':
case 'T': countT++;
break;
case 'e':
case 'E': countE++;
break;
case 's':
case 'S': countS++;
break;
// Print the results
System.out.println ();
System.out.println ("Number of blank spaces: " + countBlank);
System.out.println ("Number of A's: " + countA);
System.out.println ("Number of T's: " + countT);
System.out.println ("Number of E's: " + countE);
System.out.println ("Number of S's: " + countS);
System.out.println ();
}

Ok well I don't really understand what you're saying, but here's an improved version of my code and I can get it to work, but I don't know how to turn the "do while" loop into just a "while" loop.

          String quit = new String("quit"); //String wasn't initialized
          Scanner scan = new Scanner(System.in);

Is there a way to run a For Loop independently within a While Loop in LabVIEW 2013?

In my program I would like to run a For loop inside of a While loop, and have them run independently, at their own execution rates. As a test, I wrote a simple VI with a While loop with 1 second timing, and into this I inserted a For loop with 3 second timing. I created indicators for both iteration terminals. Upon running the VI, I found the While loop waits for the For loop to run N times before the While loop executes again. I also found that sometimes the first iteration of the For loop will end at 1 second rather than 3 seconds, and the STOP button to terminate execution of the While loop does not always work.
Solved!

Thanks, how would you synchronize the loops? I have gone through the Getting Started exercises and manual.
Why would synchronization matter? Did you want them to run independantly at their own speed or not?
Regardless, there's a synchronization pallette with functions for this, as Occurance.
Other solutions include a common loop counter and a case structure executing every X'th iteration, or having the faster loop send a queue or event every X'th loop that controls the slower loop.

How can I include a parsys inside a javascript function.

I am using radio button provided by CQ5.4.
I am writing a javascript function which checks whether a radio button is being clicked or not..
If the radio button is being clicked an alert window is opening ..this means that function is being called when radio button is being clicked.
but when I try to include parsys instead of alert window, when the radio button is being clicked..the parsys is not appearing..
Can u please help me that how should i write the "<cq:include>" for parsys inside the javascript function so that it starts appearing on click of the radio button.
THANKS
ASHWANI

Ashwani,
I would recommend detecting the WCMMode and always showing the parsys if the page is displaying in edit or design mode:
http://dev.day.com/docs/en/cq/current/javadoc/com/day/cq/wcm/api/WCMMode.html
Unless there is a really good reason to hide the section from authors, it's generally confusing to authors to hide a section. Additionally, hiding a parsys in JavaScript can cause strange artifacts as the drag and drop section of the parsys won't be hidden with the content of the parsys.

Parallelized for loop. Searching for a one-line solution

Hi.
In an usual day I do a lot of for loops inside of command line. But I noted that my loops don't use the full power of my dual core processor, they only use one processor.
A lot of the loops I do have independent interactions in the sense that a interaction code don't need the results of another interaction. This is the simplest problem in multiprocessing, I only need to execute N process in parallel.
I'm searching for a one-line solution that I can use in place of a 'for i in *.txt; do echo $i;done'. With one-line I means that can be used as one-line but the implementation can be longer. And can be in any programming language.
For now I'm using the following small python solution (the smallest I could get)
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from multiprocessing import Pool
from glob import glob
from subprocess import call
def f(x):
call(['asy', '-f', 'png', '-render=0', x])
pool = Pool(processes=4)
pool.map(f, glob('*.asy'))
But I like something that can be integrated in my "shell life". Anyone know a solution for my problem?

Delayed Movement For Loop

I know this question has probably been asked and answered before, but after searching/reading in the forums, I'm still confused.
So I would like my VI to effectively move a stage a given distance with incremental sizes with pauses of between each step.
Effectively: "Go To" _____ With X step size: causes the VI to: move, pause, move pause...etc until the stage has reached the end.
To accomplish this I set up a for loop inside a case structure, and took the "Go To" / by Step Size to get the number of iterations the loop aught to run (labview apparently rounds the double result to the integer form), and then I send the "Step Size" to the MoveAbs VI.
I am not sure if my logic is terribly off, but when I perform the command, the stage at least moves, but not to the correct location.When I inserted probes, they list the correct values being sent to the subvi's etc...
Does anyone have an idea why this would not work? Any better ideas to institute this type of motion?
Thanks

delayedmotiontrial2.vi ‏85 KB

Hey Tim,
I've got another question for you--I've been working on the program and I think I finally understand the basic outline. I've been trying to add other subvi's to increase functionality and I came across a problem:
The error list says that the selector values of the case structure are not unique--which is true of the program I am sending you. So naturally I deleted the extra "VI INI" which was tagged onto the default case. However doing so caused my program to crash--or more accurately cycle in an infinite loop. The program initializes over and over again. The "INI VI" sends another "INI VI" to the array and gets stuck.
I am not quite sure what is wrong, because when I looked at the original program you had sent to me, and earlier versions I had edited, I noticed that they have the same code within the "INI VI" case...in addition, now when I open previous programs--that were functioning perfectly well before--I get the same error message complaining about "not unique selector values". I honestly don't recall ever adding "INI VI" to the default case...
I am attaching the program and was wondering your thoughts, especially given the retrospective error...
Let me know if I was unclear in explaining the problem etc...and thanks again for your help. Others' input welcomed too!

Creating an array in a 'for' loop (resetting loop count)

Hi,
I am trying to integrate an acceleration signal coming from a CRIO analogue input to obtain the speed and then further integrate to get the displacement of a vibration system.
I understand that in order to perform the integration, an array has to be fed in. My problem is that I could not buffer the signal in a buffer block as I couldn't find any buffer blocks. so I decided to create my an array of data using a 'for' loop. The 'for' loop nests inside a timed loop. The problem that I got stuck at is how to reset the 'for' loop in order to refill the buffer again at every iteration of the outer timed loop.
I have attached the code if that helps. Note that I am using labview 2013.
I would be gratefull if someone who had encountered a similar issue before can help me.

Dear Altenbach,
Many thanks for your reply.
I need to make it clear that I have not had enough hands-on with labview, I have only used it for sometime in the past and now I have to in order to perform some active damping on a 50Hz running machine. I must stress the fact that what i find more intuitive to do in a different programming language (matlab or C) is not as straightforward in labview. so please bear with me if my code has basic mistakes .
All what i am trying to do is obtain the speed and position from an acclerometer signal. unfortunately i dont have a position sensor so i have to measure acceleration then perform time integrations in order to obtain the speed and position respectively. I am using a compact Rio (later in FPGA mode) to take physical measurements of acceleration from the vibratory machine and where i managed to do this bit successfully. when it came to performing the integration, i had to create an array inside my timed loop since i couldn't find a buffer block. I implemented a 'for' loop inside a timed loop in order to build the array. however i got stuck at resetting the count of the 'for' loop in order to refill the array with new values at every new iteration of the outer timed loop. unfortunately, even a sensible answer has been suggested before, i dont seem to have been capable of doing it yet. I really spent all my day trying to figure a way out but not achieved it yet, nevertheless I have learnt many many things by playing around.
I would be gratefull if you could comment on a possible way of doing what i am trying to do.
Kind Regards
Ali

How to create for loop USING a while loop

Hi, I would like make a for loop inside of a while loop because I want to control the i count of the loop, and overall, more control over the loop. From what I understand, labVIEW's for loop doesn't let me change where the i count starts. It always start at i=0, and what I want to do is be able to jump to specific loop iterations and then continue from there.
Thank you.

That is not the same as the earlier examples.
If you want 10 counts and start at 0, then the stop terminal will stop after 10 times. Just like you get when you wire 10 into the N terminal and don't have a conditional loop.
If your start value is larger, let's say 9, then your loop will only run 1 time because i=0 on first iteration + 1+ 9 (start value). 0 + 1 +9 = 10.
If your start value is larger than 10, then it will run 10 times again because on the intial iteration the result of your comparison is already greater than 10 and won't stop, and will never be equal on later iterations.
So your example does not even give consistent results depending on the value you use as the start value.
(Just to note, my earlier examples may not all be identical results as I didn't try to verify all the stop conditions nor the array that is output by the ramp function. I could be off by one iteration here or there. But they should be good enough to point out distinctive ways to accomplish what the OP asked for.)
