Append a constant string to every element in an array

Hi Friend,
I have a small stuck in my labview program that is I need to append a constant string to each element of an array. Could someone provide guidance on this? Prior thanks to your help.
Have a nice day!
Lee Joon

Pass the array into a for loop with autoindexing; concatenate each element with the constant and then use the array output from the loop...
I was a few seconds behind the post above; great minds think alike!

Can;t find what is wrong. Trying to add elements in two arrays

Hello everyone
I'm trying to take as input two numbers, convert them to arrays and add all the element of the array one by one. I want the result to be the sum of every element of the array. Let's say array1={1,2,3,4} and array2={2,6,4,3} I want the final result to be 3877.
If the sum of one element of the array is greater than nine, then I would put zero and add 1 to the element on the left.
Here is the code:
import javax.swing.JOptionPane;
public class Main {
    public static void main(String[] args) {
        String numberOne = JOptionPane.showInputDialog
                                ("Enter the first number: ");
     String numberTwo = JOptionPane.showInputDialog
                                ("Enter the second number: ");
        //compare string length and make them equal length
        int[]n1 = toArray(numberOne); // my first array
     int[]n2 = toArray(numberTwo); // my second array
     //call the method that ads both strings
     int[]finalArray = arrSum(n1,n2);
       JOptionPane.showMessageDialog(null, "The sum of the two numbers is: "
               + finalArray);
    }//end of main
    //method to create an array from a string
    public static int[] toArray(String str)
            int[]arr = new int[str.length()];
            arr[0]=0;
            for (int i=1; i<str.length(); i++)
          arr= Character.digit(str.charAt(i),10);
return arr;
}//end of toArray
//method to add arrays by elements
public static int[]arrSum (int[]arr1, int[]arr2){
for (int i = arr1.length-1; i >=1; i--)
int sum = arr1[i] + arr2[i];
if (sum > 9)
          { sum -= 10;
          arr1[i-1]++;
return arr1;
}//end of arrSum method

The best advice I can give you is to break your problem up into smaller pieces. First, focus on a method that converts an input String into an array. When you have that working perfectly, then focus on creating a method that "adds" two arrays with the logic you described. When you have that working perfectly, then combine the two different pieces.
Why does your for loop in toArray( ) start with 1? The first index of a String, array, or pretty much anything else, is zero.

How can I change the properties of only one element in an array of booleans?

I'm displaying an array of booleans to my operators, with each boolean in the array representing some system status check. Some of these checks are critical and some are not, therefore I want some of these booleans to have a different color when in the TRUE state (Red for the critical ones and Yellow for the non-critical ones). I can change the boolean colors with a property node, but that effects every element in the array. Is there any way to change a property of an individual element in an array? I know that I could take the incoming array and break it into two arrays - one for critical and one for non-critical, but this system is replacing an older system and the operators are accustomed to seeing their indicator lights a certain way and I'm trying to replicate what they had exactly.

Here's what I had in mind
Of course you can use as many colors as you want.

Adding CDATA To every element in xml _ JDOM

Hi,
I need to parse xml using JDOM and add
CDATA to every element.
Could anyone help me in that ?
When I append CDATA using org.jdom.Element.setText("<!CDATA"+Mystring +"]]>" );
CDATA has been treated like text but not as an instruction .

Question: Please see the code below.............
I am copying a text which is in Hindi(DBWT-yogesh font) in JTextPane. When I am trying to retrieve hindi text from JTextpane using getText() I am obtaining hashampersand123,hashampersand156(hashsymbol,ampsymbol,123;like that ) some thing like this.
If I dont set contentType to text/html and use getText()
I obtain some junk characters. If I copy those junk characters in xml
and view the xml with notepad and change the font to DBWT-yogesh
I can see hindi text.
I need to setContentType to html because I want to display text
as bold or italic depending on html tags in content. when I use getText() I obtain some thing like this. If I store these characters even after changing font to DBWT-Yogesh I am not able to see hindi text.
I want to convert (hashsymbol,ampsymbol,123;like that ) to junk characters so that when I change font using notepad I must be able to see hindi text.
Please provide help............................. your earlier answer took me in the right direction.

How do you append to a "string" type field?

ABAPers,
I am trying to understand how to append values to a "string" data type in an efficient way. One way to append to a string is using "concatenate" feature.
data: myRetVal type string.
DO
CONCATENATE myRetVal ',' myNewData INTO myRetVal.
ENDDO.
However, CONCATENMATE is not efficient in this scenario. Each time you call it, myRetVal gets copied into myRetVal all over. As the string grows, this statement will execute slower and slower.
The other option I thought is to use offset mechanism.
MOVE myNewData to myRetVal+myRetValLen.
However, it appears "string" and "xstring" type fields do not support offset and length operations.
Is there a third choice that I am missing?
Thank you in advance for your help.
Pradeep

There is no such operator.
But if just using literals, you can use the &, like this.
data: string type string.
string = 'This is the first part ' & 'This is the second part'.
Again, this will not work with variables.

NS0 namespace in every element after mapping

Hi All,
We have a scenario IDOC --> XML file on a file share. I created a free style data type for the XML message and the mapping objects. When I test the message mapping, every XML element gets the ns0 namespace before the tagname. The namespace prefix is ok to be mentioned on a root level, but not with every element. Can we configure something that this behavior is not occuring anymore?
Example current result:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:OrderCreateNotification xmlns:ns0="urn:mc-nl:procurement:boras:boras">
<ns0:OrderNumber>4550000037</ns0:OrderNumber>
<ns0:DocumentDate>20140722</ns0:DocumentDate>
<ns0:OrderItem>
     <ns0:ItemNumber>00001</ns0:ItemNumber>
     <ns0:Unit>ST</ns0:Unit>
     <ns0:Quantity>100.000</ns0:Quantity>
     <ns0:NettPrice>10000</ns0:NettPrice>
     <ns0:PurchaseRequisitionItemNumber>00000</ns0:PurchaseRequisitionItemNumber>
     <ns0:TaxRate>21.00</ns0:TaxRate>
</ns0:OrderItem>
</ns0:OrderCreateNotification>
I expected to have it like this:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:OrderCreateNotification xmlns:ns0="urn:mc-nl:procurement:boras:boras">
<OrderNumber>4550000037</OrderNumber>
<DocumentDate>20140722</DocumentDate>
<OrderItem>
     <ItemNumber>00001</ItemNumber>
     <Unit>ST</Unit>
     <Quantity>100.000</Quantity>
     <NettPrice>10000</NettPrice>
     <PurchaseRequisitionItemNumber>00000</PurchaseRequisitionItemNumber>
     <TaxRate>21.00</TaxRate>
</OrderItem>
</ns0:OrderCreateNotification>
With the data type it is possible to define the property "qualify schema", but it doesn't seem to do anything.
I know of the possibility to use the XML Anonimizer module, but I was hoping that we can configure this in a standard way.
kind regards,
Mark

Hi All,
Issue was solved by defining the value "None" in the Qualify Schema option + reimporting the message types into the message mapping after making the Qualify Schema change. The XML structures didn't got refreshed automatically.
Everything is working normally now with the ns prefix only on root level.
Regards,

How to write the map expression for a const string

hi all,
i am trying to map from source table A to target table B. Table B has a column that A doesn't have and the column type is string.
what should i do if i want to keep this column a const string like "abc"? How to write the map expression?
Setting a default value like "abc" of this column in database is not available .
please try to help, thanks a lot.

Hi jun,
You mean, u want to give some hard coded value to a specific column in mapping?
If so , give 'abc' in the target column and execute it on Target.

Printing every possible pair combination of elements in two arrays??

Hi there,
I'm trying to implement the problem of printing every possible pair combination of elements in two arrays. The pattern I have in mind is very simple, I just don't know how to implement it. Here's an example:
g[3] = {'A', 'B', 'C'}
h[3] = {1, 2, 3}
...code...??
Expected Output:
A = 1
B = 2
C = 3
A = 1
B = 3
C = 2
A = 2
B = 1
C = 3
A = 2
B = 3
C = 1
A = 3
B = 1
C = 2
A = 3
B = 2
C = 1
The code should work for any array size, as long as both arrays are the same size. Anybody know how to code this??
Cheers,
Sean

not a big fan of Java recursion, unless tail recursion, otherwise you are bound to have out of stack error. Here is some generic permutation method I wrote a while back:
It is generic enough, should serve your purpose.
* The method returns all permutations of given objects. The input array is a two-dimensionary, with the 1st dimension being
* the number of buckets (or distributions), and the 2nd dimension contains all possible items for each of the buckets.
* When constructing the actual all permutations, the following logic is used:
* take the following example:
* 1    2    3
* a    d    f
* b    e    g
* c
* has 3 buckets (distributions): 1st one has 3 items, 2nd has 2 items and 3rd has 2 items as well.
* All possible permutaions are:
* a    d    f
* a    d    g
* a    e    f
* a    e    g
* b    d    f
* b    d    g
* b    e    f
* b    e    g
* c    d    f
* c    d    g
* c    e    f
* c    e    g
* You can see the pattern, every possiblity of 3rd bucket is repeated once, every possiblity of 2nd bucket is repeated twice,
* and that of 1st is 4. The number of repetition has a pattern to it, ie: the multiplication of permutation of all the
* args after the current one.
* Therefore: 1st bucket has 2*2 = 4 repetition, 2nd has 2*1 = 2 repetition while 3rd being the last one only has 1.
* The method returns another two-dimensional array, with the 1st dimension represent the number of permutations, and the 2nd
* dimension being the actual permutation.
* Note that this method does not purposely filter out duplicated items in each of given buckets in the items, therefore, if
* is any duplicates, then the output permutations will contain duplicates as well. If filtering is needed, use
* filterDuplicates(Obejct[][] items) first before calling this method.
public static Object[][] returnPermutation(Object[][] items)
     int numberOfPermutations = 1;
     int i;
     int repeatNum = 1;
     int m = 0;
     for(i=0;i<items.length;i++)
          numberOfPermutations = numberOfPermutations * items.length;
     int[] dimension = {numberOfPermutations, items.length};
     Object[][] out = (Object[][])Array.newInstance(items.getClass().getComponentType().getComponentType(), dimension);
     for(i=(items.length-1);i>=0;i--)
          m = 0;
          while(m<numberOfPermutations)
               for(int k=0;k<items[i].length;k++)
                    for(int l=0;l<repeatNum;l++)
                         out[m][i] = items[i][k];
                         m++;
          repeatNum = repeatNum*items[i].length;
     return out;
/* This method will filter out any duplicate object in each bucket of the items
public static Object[][] filterDuplicates(Object[][] items)
     int i;
     Class objectClassType = items.getClass().getComponentType().getComponentType();
     HashSet filter = new HashSet();
     int[] dimension = {items.length, 0};
     Object[][] out = (Object[][])Array.newInstance(objectClassType, dimension);
     for(i=0;i<items.length;i++)
          filter.addAll(Arrays.asList(items[i]));
          out[i] = filter.toArray((Object[])Array.newInstance(objectClassType, filter.size()));
          filter.clear();
     return out;

Click every element in a window via GUI Scripting

White spaces append to restulting strings

Hello All,

QUERY:

Results (there is white spaces added right after the username, as the result shoudl have been "intm","root" as opposed to "intm                                "

How many elements in an array?

Sounds like a simple question, right?
Apparently not.
LV 2010
I have a huge data structure, stored in DataLog files (thousands of them).
I want to convert this structure to Name/Value pairs ("Operator_Name", "Joe Smith"), for use in a TDMS file.
The structure is a cluster, with various clusters inside that, and inside those are DBLs, strings, BOOLs, other clusters, arrays, you name it.
My strategy is to obtain the CONTROLS[ ] property of the outermost cluster and call this VI.
The VI processes each control, decoding what type it is and handling it accordingly.
It works fine for STRINGs, NUMERICs, ENUMs, BOOLEANs, COMBOBOXes, TIMESTAMPS, and CLUSTERs.
For those simple ones, I use the LABEL.TEXT as the NAME and get the value (based on what type it is) as the VALUE.
For a CLUSTER, I get the CONTROLS[ ] array of the cluster and call myself recursively, to handle all the elements within the sub-cluster.
That all works fine.
But to handle an ARRAY, I'm stumped.
Attached is the code showing the case for an ARRAY.
What I'm doing is getting the CLASS NAME of the current control.
I LEGALIZE the label name (turn spaces into underscores, and maybe other special handling later).
For an ARRAY, I cast the generic CTL reference into an ARRAY reference, and get its VALUE.
I want to loop over each element of the array, and modify the name by the index number, and process each element.
There are arrays of STRINGS, arrays of DBLs, arrays of CLUSTERs - all types.
The question is - how many array elements are there?
The constant "10" in this diagram is a dummy - just there to see if it works.
it does work, except that I get 10 sets of answers, whether the real array has 2 or 20 elements.
I thought the array's VALUE would be an ARRAY of VARIANTs, but no - it's a single VARIANT.
I can't use VARIANT to DATA on the array's VALUE - I don't know what TYPE the array is.
I thought maybe the ARRELEM refnum would be NIL if I was past the end, but that's not the case - there's only one refnum for any array element, whether it exists or not.
If I check for errors, it complains that I cannot set the INDEXVALS property of a strict typedef array, even though it works just fine.
If there was a method to SELECT ALL on the array, I could use the SELECTION SIZE to figure out how many elements there are, but I see no such method.
The NUMBER OF ROWS / COLUMNS refers to the number of VISIBLE rows/columns, and has nothing to do with how much data is present.
So... How do I find out how many elements are in the array?

The ArrElem reference property is not a reference to any particular element of the array.
On the contrary, it is a reference to the element addressed by the current ARRAY INDEX(es).
That's why my code above can read out the values for element 0, element 1, etc. I've verified that this works.
There is only one set of PROPERTIES for the array elements; if you use the ArrElem refnum to set a background color of blue, then ALL elements turn blue, but you can obtain the VALUE of a given element by setting the ARRAY INDEX(es) and accessing via the ArrElem.
I was thinking that maybe LabVIEW did a trick by setting this to NIL to indicate "no such element", but that's not the case.
In any case, the question remains: How do I determine how many elements there are?
The VALUE of the array is a variant: just what is in that package?
As I said, I don't see how to use VARIANT TO DATA; I don't know what kind of data it is.

Summing specified elements in 2D array.

Hi!
I have a little problem with summing elements in 2D array… I have signal from 64 sources in the 2D array - 64 colums and (time*sampling) rows. I have to add some deley to every signal (different for each) and then sum signals from all of the sources. I hope the picture below explains what I have to do:
What's more - I have a 2D array of delays. By now I'm doing this by creating an 1D array of "0" and then putting in it the 1D signal array at index specified by delay value.
And it works ok. But... It takes long time... Is there any method to do the summing "at once" for all the delays? Is there sth like "pointer" in array, so I could take elements from the array from specified element?
Rgds,
Mordimer

One problem with your solution is also that the subset is of variable lenght due to truncation, so the shift register needs to be reallocated whenever the size changes. (Even if you define a lenght for the subset, you run out of elements and the result will be shorter!). You might want to e.g. truncate all to the shortest subset (longest delay) before summing for better inplaceness.
Why do you have a 2D array of delays? isn't the time spacing of each column constant?
What is your definition of "takes a long time": microseconds?, minutes?

Hihow to insert 2 elements into 2D array?

Hi I had a hard time figuring out how to insert 2 elements into 2D arrays.
I tried using replace and insert array functions but it does not work right way.
I am using LV7.1. See the pic below.
How do I insert elements in that way?
Pls advise
Clement

Well, "replace array subset" is not the right tool, because it keeps the size of the array constant. Insert into array only works for entire rows or columns.
You need a hybrid approach, because you want to insert elements at the beginning of column 1 while padding the remaining columns to the new lenght of column 1. This won't be efficient but there are plenty of ways to do that (here is one example with DBL arrays, should work equally well for string arrays as in your case).
How much flexibility do you need? Is it always at the beginning of the first column? Are the arrays huge (=is performance an issue)? Is this a rare operations or do you constantly need to do this (e.g. inside a loop).
In any case this seems like a rather arbitrary and somewhat silly operation. What is the practical purpose?

How to insert elements into an array after each iteration of a for loop

I am new to labview and working on an application where I am supposed to store an element into an array (without overwriting) after each iteration in a for loop. I have tried using Build Array Function keeping the indicator outside the for loop and played with indexing but didn't work. Please suggest me an idea how to do it.
Thanks

Thank you for your suggestion.Here is my actual application attached . In the first image, a difference in time is evaluated and an enum const of insert into array is passed to the shift register where it takes to Insert element into array phase (Second image). I need to enter the time difference into an array after every loop iteration. Please have a look and could you let me know where I am mislead.
