Converting array of strings using SCMS_STRING_TO_XSTRING

Hello all,
FM SCMS_STRING_TO_XSTRING can be used to convert a String to a XSTRING and then we can use FM SMUM_XML_PARSE to parse the XML.
Now I will have a array of strings as an output from a web service and I need to parse them .. so the Function modules mentioned above are used for a single string but how to convert the array of strings??
Please suggest me on how to proceed.
Thanks in advance,
Regards,
Suman.

Hi Raja,
Thanks for your suggestion.
I have yet to try this..I will update with the results.

Converting Array of string to an array of integers

I have a problem converting a array of string to array of int's
This is my code...
String[] forminfo = request.getParameterValues("forsendur");
      int[] forminfoInt = Integer.parseInt(forminfo); This is the error message:
Incompatible type for method. Can't convert java.lang.String[] to java.lang.String.
                      int[] forminfoInt = Integer.parseInt(forminfo);
                                                           ^can anyone help me with this?

ParesIn methos returns a int buto not a int[]. You must iterate along the String array and perform the methos for each element setting the return value into the element of the int array
Ej:
int[] intArray = new int[stringArray.length]
for(int i = 0; i < stringArray.length; i++)
intArray[i] = Integer.parseInt(stringArray);

Converting from spreadshet string to array and then back to spreadsheet string

My questions is; why is the Spreadsheet string to array function creating more data than the original string had when you change the array back into a spreadsheet string. Im trying to analyze a comma delimited file using array functions since my column and row size is constant, but my data varies. Thus my reason for not using string parsing functions which would get more involved and difficult. So, however, after i convert to a 2D array of data from the comma delimited file I read from, and then I convert back to string using the Array to Spreadsheet String, I get added columns to the file, which prevents another program from receiving these files. Also, the data which I am reading is not all contiguous, it has gaps in some places for empty data. Looking at the file compared to the original after it has gone from string to array and then back to string again, looks almost identical except for the file size which got larger by 400 bytes and where the original file has empty spaces, the new file has a lot of commas added. Any idea?
Charles

The result you get is normal when the spreadsheet string contains rows of uneven length. Since the array rows have the same number of elements, nil values are added during the coonversion. And of course, the back to string conversion keep those added values in the string, with the associated commas.
example : 3 x 3 array
1,2,3
4
5,6,7
is converted into
1 2 3
4 0 0
5 6 7
then back to
1,2,3
4,0,0
5,6,7

Converting Datetime in String in map

Hello all,
I am reciving a message from a system A, in which I am receiving field DOB as datetime and I am sending same message to system B , problem is that system B not able to handle DOB at there end as datetime - I have checked at BizTalk side that DOB
is going correct so issue is at system B side. now system B wants BizTalk system to send them DOB field as string.
What could be the possible way's to do this ?
1) We can change both schema System A schema and System B schema and map them is one way .
2) Can we take datetime and convert it to string using some funtoid ? and send that string to system B ? How ?
Is there other way for this ?
Thanks,
Nitin
Thanks and Regards, Nitin.

Hi Nitin,
First find out how the destination system consumes the datatime value. Some system would consume the value in the datetime field as string. It could be the problem in the format of the datetime. Ask them about their expected datetime format. For example
"2004-09-23T10:20:00.000-05:00" is the standard datetime format produced when you set a field as xssd:datetime. May be the destination system not able to handle this format.
If the issue is in the datatype i.e. in the way client consume, the datatype of the destination schema matter:
Then update the destination schema's to have string datetype. And simply map the value from the soruce's datetime field to destination schema's update string field. You don't need any scripting fuctiond to convert the data type. BizTalk's mapper would handle
it.
If the issue is in the date format i.e. in the way client consume, the datatype of the destination schema doesn't matter, and if the actual problem is in the format:
Then update the destination schema's to have string datetype. Use a scripting fuctiond as suggested by others and do the conversion in the script.
If this answers your question please mark it accordingly. If this post is helpful, please vote as helpful by clicking the upward arrow mark next to my reply.

Is there an easy way to convert a long string into an array?

I can convert a long string into a 1-d array by parsing and using build array, but I would like to know if there is a function to make this easier.
For example:
from/   aaaaaaaabbbbbbbbccccccccdddddddd         (string of ascii)
to/       an array that is 1-d with each element having eight characters
          aaaaaaaa
          bbbbbbbb
          cccccccc
          dddddddd
Thank you.
Solved!
Go to Solution.

Try something like this:
(If you can guarantee that the string length is an integer multiple of 8, you an drop the two triangular modes in the upper left. )

Having trouble converting array to spreadsheet string, storing the file and coverting back to array with complex numbers

I am working with a network analyzer. I have arrays made of 5 columns the first consisting of an integer and the next four consisting of complex numbers. I am converting the array into a spreadsheet string and then saving the file using the write characters to a file VI. That seems to work well as when I open the file in Excel all the data is there. However when I try to reverse the process, open file and convert back to array, I loose some of the data. Specifically the imaginary parts of my complex numbers are all going to zero. I have narrowed down the problem to be in the conversion from spreadsheet string to array and vice versa. I
think the problem may be with the 'format' input to the VI. I do not have an adequate resource for this so I am not sure what to put in to accomplish my task. Any takers?

Hi Biz
I don't think there is a direct way of converting a complex number to a
string, so when you convert the array to a spreadsheet string, the
numbers would be converted to real data.
However, you could try separating the real and imaginary parts using the
"Numeric: Complex to Re/Im" function, and then store these - either in
separate files or in adjacent columns/rows in the same file. Then, when
you read in the data again, use the "Numeric: Re/Im to Complex" function
to put the two "halves" together.
If you actually want Excel to interpret the numbers as imaginary, then
you'll probably want to create a string for each complex number of the
form "Re + Im*i" (after separating the Re and Im parts), by using
"String:Format into String" with 2 numeric inputs and the format string
"%f+%fi".
Reading the data back into Labview then would require splitting the
string into the 2 pieces by using "Stringcan from String" with 2
numeric outputs (smae precision as original numbers specified by the 2
Default Value inputs) and the same format string "%f+%fi", and then using
the above-mentioned "Numeric: Re/Im to Complex" function. It worked for
me, so if you can't follow what I am describing, send me an email and I
can email you what I did (LV 5.1.1).

How to convert an int array to string array?

Hi,
Can anyone please help me with this question?
int number={4,6,45,3,2,77};
I like to convert this into a list and sort
List mylist = Arrays.asList(number);
Collections.sort(mylist);
But first I need to convert the int array to String array.
Please advise. Thanks.

If you want to convert your int array to a String array, you have no choice but doing a conversion element by element in a for loop.
However, if the sort method doesn't behave as desired, you can use the one with 2 parameters, the second parameter being a comparator class.

What is the best way to convert a cluster into byte array or string

I'm writing a program that sends UDP packets and I've defined the data I want to send via large clusters (with u8/u16/u32 numbers, u8/u16/u32 arrays, and nested clusters). Right before sending the data, I need to convert the clusters either into strings or byte arrays. The flatten to string function is almost perfect for this purpose. However, it's appending lengths to arrays and strings which renders this method useless, as far as I can tell.
As I have many of these clusters, I would rather not hard code the unbundle by names and converting/typecasting to byte arrays or strings for each one.
Is there a feature or tool I am overlooking?
Thank you!

deceased wrote:
Flatten to string has a boolean input of "Prepend string or array size" ... The default value is true.
That only specifies if a string or array size should be prepended if the outermost data element is a string or array. For embedded strings or arrays it has no influence. This is needed for the Unflatten to be able to reconstruct the size of the embedded strings and arrays.
The choice to represent the "Strings" (and Arrays) in the external protocol to LabVIEW strings (and arrays) is actually a pretty bad one unless there is some other element in the cluster that does define the length of the string. An external protocol always needs some means to determine how long the embedded string or array would be in order to decode the subsequent elements that follow correctly.
Possible choices here are therefore:
1) some explicit length in the protocol (usually prepended to the actual string or array)
2) a terminating NULL character for strings, (not very friendly for reliable protocol parsing)
3) A fixed size array or string
For number 1) and 2) you would always need to do some special processing unless the protocol happens to use explicitedly 32 bit integer length indicators directly prepended before the variable sized that.
For number 3) the best representation in LabVIEW is actually a cluster with as many elements inside as the fixed size.

"Using a CIN to Create an Array of Strings in LabVIEW" example crashes LV on Linux

This code is badly broken. In addition to resizing the actual handle to hold the number of string handles you also would need to create the string handles itself before attempting to write into them. NumericArrayResize is the fucntion to use as it will either resize an existing handle (if any) or create a new one if the value is uninitialized (NULL).
/* resize strarr to hold handles to NUMSTRINGS strings */
err = SetCINArraySize((UHandle)strarr, 0, NUMSTRINGS);
if (err)
goto out;
/* perform this loop once for each element */
/* of array of strings being created */
for (i = 0; i < NUMSTRINGS;) {
LStrHandle handle = (*strarr)->arg1[i];
/* determine length of string that will be element of strarr */
strsize = StrLen(str[i]);
err = NumericArrayResize(uB, 1, &handle, strsize);
if (err)
goto out;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
/* moves strsize bytes from the address pointed to */
/* by str[i] to the address pointed to by the data pointer in the handle */
MoveBlock(str[i], LStrBuf(*handle), strsize);
/* manually set size of string pointed to by *strarr */
(*((*strarr)->arg1[i]))->cnt = strsize;
/* manually set dimSize of strarr */
(*strarr)->dimSize = ++i;

Using an array of strings to name an object

Hey everyone
I have an array of strings that are supposed to be the names of each panel in a grid, but I dont know how to use the string values to name the panels. From searching the forums almost everything refered to using a Map to do this, but I still can't grasp how to use one. Can someone help me with this?
import java.awt.*;
import javax.swing.border.*;
import javax.swing.*;
public class test
    public test()
    public JPanel grid()
         JPanel mainPanel = new JPanel(new GridLayout(10, 10));
         String [] names = new String[100];
         Border innerBorder = BorderFactory.createLineBorder(Color.black, 1);
          for (int i = 0; i < 100; i++)
               names[i] = "Panel" + i;
          for (int r = 0; r < 100; r++)
               String varName = names[r];
               JPanel /*I would like the JPanel to be named what the string varName is*/justSoItCompiles = new JPanel(new GridLayout(2,1));
               /*The JPanel above*/justSoItCompiles.setBorder(innerBorder);
               mainPanel.add(justSoItCompiles);
          return mainPanel;
}Thanks in advance

You just make a Map as:
Map<String, JPanel> panelMap = new HashMap<String, JPanel>();then add a panel as
panelMap.add("Panel1", new JPanel());then you can do whatever with it by saying
panelMap.get("Panel1").add(something);Make sense?

Using JNI to pass an array of Strings to C and back from C

I have some C code that I want to integrate with a new Java application and I need to be able to pass an array of strings to the C program and then the C program needs to be able to build an array of strings that is passed back to the Java program. I've got the first part working so that I can pass an array of strings to the C program and display them, but I can't figure out how to build the strings in C so that that when Java gets back control, it can display the strings tha were built in the C program.
Has anyone done this? Do you have some sample code?

I have a program which is written in C. I can give you the whole project as it is in a zip file. You'll need VC to work with it. By the way, I am using Windows for development. Should you need it, I'll mail you the same. Give me your mail address.

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

Convert an array of strings into a single string

Hi
I am having trouble trying to figure out how to convert an array of strings into a single string.
I am taking serial data via serial read in a loop to improve data transfer. This means I am taking the data in chunks and these chunks are being dumped into an array. However I want to combine all elements in the array into a single string (should be easy but I can't seem to make it work).
In addition to this I would also like to then split the string by the comma separator so if any advice could be given on this it would be much appreciated.
Many Thanks
Ashley.

Well, you don't even need to create the intermediary string array, right? This does exactly the same as CCs attachment:
Back to your serial code:
Why don't you built the array at the loop boundary? Same result.
You could even built the string directly as shown here.
