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.

How can I have each pass through a for loop communicate with a new indicator?

Hello,
I am using 16 color boxes to indicate how 16 channels are behaving. If a color box is blue, its respective channel is running correctly, red means it has failed etc. I am continuously checking each channel using a loop, and I wanted to update the channel colors every loop. I have made an array of 16 numbers corresponding to the color I wish to have (which are blue = running, red = failed, green = completed, black = not in use). However, I cannot find a way to pull these 16 numbers out of the array and to the color boxes short of 16 index arrays connected to the color boxes.
I understand how to convert each individual number to a color, I just don't know how to use a 16 times for loop to communicate with a different color box each pass through. Is there any way to do this or should I just go for brute force?
Thank you.
Solved!

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

For-Loops: The question no one asks.

Why don't For-Loops have a premature exit capability --- i.e. why didn't
NI include the exit capability that exists in other languages? Is it a dataflow
thing? I don't see how. Just curious.

Jay,
I have to say I`m no programming Guru, but isn`t a State Maschine based on a
case (Switch) statement? This statement does allow the user to hop to and
fro within a certian pre-defined space, but the use of a GOTO is, as far as
I am aware, not limited to a particular region of the code. At least with a
switch statement (Case) the beginning point of each "choice" is well defined
and fixed, therefore reducing the change of mistakes.
just my 2 cents

For loop array index not from 0

HI!
I have an array that is wired into a For Loop. Inside the For Loop there is already a single Array content available as there is this autoindexing feature (?). I do want to change the Array from a certain position different from 0 onwards to the end e.g. change positions 4, 5 and 6 in a for loop executing 3 times. But the for loop and the autoindexing feature start at 0. Can I change this in an elegant way. At the moment I'm running thru the hole array and begin changing at a certain position.

Yes, disable autoindexing on the tunnel and use "index array" inside the loop. Use [n]+4 as index and wire a "3" to the loop count in your particular example.
If you want to keep the entire array and just replace a few elements with updated values, the array needs to be fed in via a shift register. Write the new elements at the desired position using "replace array subset" (see attached very simple example).

For loops & inheritance question

I am trying this exercise dealing w/inheritance. I enter at command line a random number of c's, s's and m's. for checking,savings and money market. I then parse the string and check for the character. From there I create one of the accounts. then I am supposed to make a report that displays the past 3 months activities. the first account created gets 500 deposit the from there each account after the first gets an additional 400. so it would be: 500,900,1300,etc. Here is what I have so far, but the report part is where I can't figure out exactly how to go about solving it. Thanks in advance.
public static void main( String args[] ){
     int intDeposit = 500;
     char charTest;
     Object [] objArray = new Object[args[0].length()];
     for ( int j = 0; j < 3; j ++ ){                        System.out.println( "Month " + ( j +1 ) + ":" );
         for( int i = 0; i < args[ 0 ].length(); i ++ ){
          charTest = args[ 0 ].charAt( i );
                     if (charTest == 'c' ){
              BankAccount at = new CheckingAccount( intDeposit );
              objArray=at;
          else if( charTest == 's' ){
          BankAccount at = new SavingsAccount( intDeposit );
          objArray[i]=at;
          else if( charTest == 'm' ){
          BankAccount at = new MoneyMarket( intDeposit );
          objArray[i]=at;
          else{
          System.out.println( "invalid input" );
          }//else
          intDeposit += 400;
          System.out.println();
     }//for j
     for (int counter = 0; counter < objArray.length; counter ++ ){
          System.out.println( "Account Type: " +
                    objArray[counter].toString() );
          System.out.println( "Initial Balance: " +
                    (BankAccount) objArray[counter].getCurrentBalance() );
     System.out.println( "TotalDeposits: " + objArray[counter].getTotalDeposits() );
     System.out.println();
     }//for i
}//main
}//TestBankAccount.java\

The only thing I think is wrong is the following line:
System.out.println( "Initial Balance: " +                    (BankAccount) objArray[counter].getCurrentBalance() );
Should be:
System.out.println( "Initial Balance: " +                    ((BankAccount) objArray[counter]).getCurrentBalance() );

How to make for loop pass only once in a next() method

Hi everyone!
What I actually trying to do is that I have a multiple tables and from these tables I'm going to write each of it into a flatfile that is a pipe delimeted that is why I have to make a loop to know how many fields I am going to write. The code that was attached are actually working, my only concern is that it will take a longer time of processing cause every record of a table it will pass to the for loop(checking how many column) wherein number of column/ were already known on the first loop.
Hi kajbj,
I think what your trying to explain is almost the same with below code which i had already tried. The problem with this is that the every loop of the outer loop data retrieve is only the data of the first record.
               Statement sOutput = consrc.createStatement();
                        ResultSet sqlset4 = sOutput.executeQuery(xquery);
                        ResultSetMetaData rsMetaData = sqlset4.getMetaData();
                        int numberOfColumns = rsMetaData.getColumnCount();
                        String writefld = "";
                        while (sqlset4.next()) {
                             writefld = "";
                             if (sqlset4.isFirst()) {
                                for (int i = 1; i <= numberOfColumns; i++) {
                                    if (xxformatid.equals("1") || xxformatid.equals("3")) {
                                        writefld = writefld + "sqlset4.getString(" + i + ").trim()" + "|";
                            writefld = writefld.substring(0, writefld.length() - 1) ;
                            output.write("\r\n");
                            output.write(writefld);

LabVIEW 6.1 If For Loop count terminal is zero then value going through the loop is not passed on to the output of the loop

Hello, one of our customers just encountered an execution error in a vi running under LabVIEW 6.1, which doesn't exist under LabVIEW 5.1 or 6.01. I have a simple vi that has two encapsulated For Loops. Two string arrays go in, one goes out of the outer loop. Inside the outer loop the first array is indexed. The string which results from this indexing is compared with all other strings from the second string array in the inner loop. If it matches one of the strings of the second array, it is not outputted, otherwise this string goes through the inner For Loop to the output of the inner loop and from there to the output of the outer loop. The count
terminal of the outer/inner loop is connected to the Array Size of the first/second string array. If the second array is empty, that means that the element in test from the first arry cannot match anything from the second array, so the element in test is send to the output of the inner loop and from there to the output of the outer loop. This works fine in LabVIEW 5.1 and 6.01, but NOT in LabVIEW 6.1. In LabVIEW 6.1 the inner loop is never executed if the count value is zero (which is correct), but the data line running through the loop is not executed either, which is different to what LabVIEW 5.1 and 6.01 do. There, the input string is sent to the output of the inner loop correctly even if the loop counter is zero. The solution is easy - I just have to connect the output of the outer loop to the data line BEFORE it enters the inner loop. But: I don't know if this is a LabVIEW 6.1 bug or if it is supposed to be a feature, but it brings some incompatibility in programming between the
different LabVIEW versions.
Best regards,
Gabsi

Hi,
When a for-loop runs zero times, all outputs are 'undefined' (and should
be).
Besides, how would LV know what the output of a not executed routine should
be?
It might be handled differently in LV5 and LV6, which is unfortunate. In
both cases, the result is undefined.
It's not a bug. It's just something that should be avoided in any LV
version.

In some cases this does the trick. But if the data is changed in the inner
loop, this will effect the results if the N is not zero.
Technically, I think the output in this construction is also 'undefined'.
But LV handles this as expected / desired.
Another solution is to use a shift register. If N is zero, the input is
directly passed through to the output.
Regards,
Wiebe.

Coding pattern: Branching an array wire, vs. passing it through a loop?

Hello,
In the diagram below, the purple wire is branched just before it enters the timed loop.
I was wondering: Will there be any difference if, instead of branching, I take the output of the Read Variable VI and tunnel it back out (with auto-indexing)?
Thanks!

gt8860a wrote:
Hello JKSH,
Branching array wires leaves the possible of LabVIEW creating data copies, so if possible, I would avoid it. You can use the "Buffer Allocation"tool to confirm that a data copy will or will not occur.
Thanks for the tips, gt8860a!
With the specific example in my original post, if I use the pass-through wire from the Read Variable VI, would it cause the inner for-loop to rewrite the output array (of variable references) at every iteration of the outer timed loop?
gt8860a wrote:
However, in the example you have shown, the code on the right of the time structured is unreachable since the timed structure will never exit ("False" is hard wired to the conditional terminal).
In addition, the array that is passed into the "For Loop" inside the Time structure, I'm pretty sure you're going to want change the tunnels to shift registers. Otherwise, the only thing that is going to come out of that "for loop" is an array full of 0's except for the last element will be populated with the value from the shared variable. (Maybe that's what you want but then why use a For loop to read all the elements
Good catch; I didn't notice those. The example was from official NI documentation:

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.

Creating new text file (txt.) everytime a string is passed in

Dear all, need some help from you all. I am now developing a web service program to allow users to type in a string of characters. And will need to create txt. file to store this strings. Currently, i hard code the directory and the name of the txt file (e.g C:\\test.txt) does anyone know if possible solution to create new txt. file (using different names) whenever a string is passed in from the web service? I am using J2EE as programming language and BEA Workshop for Weblogic Platform version 10.
Thank You very much.

well, make the name as argument.
and new File(name)...blablablabla

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.

A single quote/apostrophe in string parameter passed to a Crystal Report with Command datasource connecting to a SQL Server database, using sqljdbc driver does not escape the special character correctly. When doing a preview in the Crystal Reports IDE it allows you to escape the input parameter as expected and work correctly, but through the JRC component it fails. For string parameters without special sql server characters I experience no problems at all. When replacing the Command with a direct table there is also no problem.
Reproduction:
1. create a database db1, create a table table1 with a String type column col1.
2. Create new report Report1.rpt, create a connection to above, Add Command using 'SELECT col1, col2, col3 FROM table1 WHERE col1 = '{?Par1}' . Add a parameter field Par1 : String
3. In your java stand alone application using JRC add the parameter Par1 with a value "Jon Doe's Value" containing a single apostrophe. Export to PDF. (I also tried MSWord and this failed too, similar behavior). Additionally, in another test try to replaceAll("'","''") to escape it, preventing the code to break, but now it does not retrieve the expected row anymore and you end up with an empty report.

Any way to pass Multiple Values for a single Label in the Parameter?

I have a Report that Contains 2 Parameters, @Customer & @Area. When trying to set up the Available Values for @Area, I'm having issues using multiple values for one Label, i.e. = "4006" Or "4610"
One of the Filters in the Report is an Operation number, which is the [OPERATION] field, which is setup as a filter on the Tablix referencing the @Area parameter.
PROBLEM: I cannot retrieve any data when trying to use the ‘Or’ Operator here. If I simply put “4006” or “4610” I retrieve data, but when trying to combine it returns no data.
Example, I need to allow a user to select ‘Chassis Incoming’, which would include data from Operations 4006 & 4610.
QUESTION:
Any way to pass Multiple Values for a single Label in the Parameter?
I realize the typical solution may be to use ‘Multi-Value’ selection, but in this case we want the User to select the Area and the multiple values for Filtering will be automatically determined for them. Otherwise, they are subject to not getting
it correct.
I have tried several different ways, such as =”4006” Or “4610”, =(“4006”, “4610”), = In(“4006”, “4610”), etc….
Note: We are using Report Builder 3.0

Based on my experience, there's no way to 'intercept' the query that gets passed back to SQL Server, so a Split wouldn't work.
Try creating either a function or stored procedure using the code below (compliments to
http://www.dotnetspider.com/resources/4680-Parse-comma-separated-string-SQL.aspx) to parse the string:
CREATE FUNCTION dbo.Parse(@Array VARCHAR(1000), @Separator VARCHAR(10))
RETURNS @ResultTable TABLE (ParseValue VARCHAR(100))AS
BEGIN
DECLARE @SeparatorPosition INT
DECLARE @ArrayValue VARCHAR(1000)
SET @Array = @Array + @Separator
WHILE PATINDEX('%' + @Separator + '%' , @Array) <> 0
BEGIN
SELECT @SeparatorPosition = PATINDEX('%' + @Separator + '%', @Array)
SELECT @ArrayValue = LEFT(@Array, @SeparatorPosition - 1)
INSERT @ResultTable VALUES (CAST(@ArrayValue AS VARCHAR))
SELECT @Array = STUFF(@Array, 1, @SeparatorPosition, '')
END
RETURN
END
Once created you can do things like this:
SELECT * FROM Parse('John,Bill,David,Thomas', ',')
SELECT * FROM (SELECT 'John' AS TestName union select 'David' AS TestName) AS Main
WHERE TestName IN (SELECT ParseValue FROM dbo.Parse('John,Bill,David,Thomas', ','))
This is what your SQL query would probably look like:
SELECT OperationID, OperationName FROM dbo.Operations
WHERE AreaID IN (SELECT ParseValue FROM dbo.Parse(@Area, ','))
You may need to fiddle around with the Separator depending on whether SQL Server inserts a space between the comma and next value.

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