Simple array of Strings
Hi, I am new to LabView, however I have programmed in various languages to a moderate level.
I have attached the vi that I am working on to test a simple array.
All I want it to do for just now so I can get my head around LabView arrays is simply add the string to the array each time the button is pressed.
So each time the button is pressed I want to add an new element to the array. So after say 10 presses there should be 10 elements
Regards,

Some general suggestions:
Use latch action boolean (right-click..mechanincal action). This way it is true until read by the code, the reverts autoamtically back to false (no need for the local variable).
Your sequence structure has no purpose. Adding to the array is basically instantaneous, so you can add the delay outside. The execution order does not matter.
Pachi: Your Current VI has no wait unless you press the button, meaning it spins like crazy, consuming all CPU while doing nothing. The wait should be outside the case.
Pachi: You need to initalize the shift register, else it remembers the data from previous runs.
Pachi: It is much less efficient to add to the beginning of the array. I recommend to add the new element to the end.
Here's a quick draft...
(personally, I would use an event structure, but this should get you started).

I have an array of channel names for a simple vi I wrote and I want to input them into the plot legend. I typically use ring controls to allow different users to select what they want to see, but beyond 3 or 4 it gets confusing. Is there a way to take an array of strings and input them directly into the legend string slots using a property node? I have spent hours searching to no avail.
Thanks!!
AdamYes, of course there is! Try this:

I need to sort an array of strings based on the number in each string.
Basically, I have a directory of files that all have the same name but each with a different number on the end.
example: image 1.jpg, image 2.jpg, etc.
When I use the List Directory function that returns an array of strings containing the file names in the directory, they don't come out in a 1, 2, 3, order like they appear in the directory. It sorts them character by character so that they come out like: 1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 2, 20, 21, 22 etc.
Is there a simple way of sorting this array of strings with the file names (as above) so that they are in numerical order?It's a while since this thread was started, but I am sure others will have use for this so here goes:
The in-built array sort function sorts the strings the same way DOS and Windows do. Microsoft has fixed this in the Explorer that comes with XP, however the rest of the OS(s) still sorts the old way.
The attached "AlphaLogical String Array Sort" VIs will sort strings arrays the same way as the new XP Explorer. There are three different implementations of the sorting, one based on the Insertion sort algorithm, a Quick Sort based on recursive calls (the most elegant way, but unfortunately LabVIEW has too much overhead when doing recursive calls so this is actually a very slow alternative) and finally the fastest; a stack based Quick Sort. There is also a test VI that will show you how the different implementations perform.
I had not used recursive calls in LV much until I made the attached quick sort and was a bit disappointed by the fact that it is so slow, but it's a good learning example...The ability to do recursive calls this way was introduced in LV7 I believe...There is an example here on the zone that shows how you can calulate a factorial by using recursive calls, however - unlike for the quick sort (normally) - recursive calls are actually not the optimal solution for that calculation.

How can I make an array of strings?
or, depending on what the heck you're talkingabout
That's bad advice now that Java is in version 5.
The standard loop is the for-each loop. If you don't
use it you're going down in complexity which is a
very bad thing according to the "premature
optimization is evil" bunch. So use for-each if you
don't want to be accused of "premature optimization"
by jverd and yawmark and other prominent members of
that bunch.Thanks for your advice. I use version 1.4.2. I did not intend to give bad advice. My post was targeted at someone who obviously did not understand "nuts and bolts" of java. It was not intended to be a lesson about "good design" or "real life applications" or "standard for loops in version 1.5". I gave an example that i feel is both adequate and appropriate for the target audience. It's intended purpose was to demonstrate very simple and basic concepts to someone who asked a seemingly simple and basic question that could possibly irritate a seasoned programmer like yourself. I have read your helpful posts in this thread and would welcome comments from yawmark and jverd also. I am sure they would be helpful to others who would read this thread in the future but their level of experience (along with Mr Warnerja) would perhaps be lost and uncomprehended by the OP. If in the context of the original question, you believe that my posts and simple examples are inappropriate, then would you kindly explain in terms that the OP can understand? Also explain (in this context) how my posts were wrong and meaningless.
respectfully yours,

H:dataTable value as array of Strings vs array of objects
I'm trying to use a h:dataTable with an h:inputText as one of the columns. If my bean returns an array of Strings, then the h:dataTable can't update them. (I added a submit button that just updates the fields and returns to the current page.) If I use an array of objects, in this case a simple wrapper class, it works. Why is this?
This won't work:
public class EmailBean {
private String[] m_emails;
public String[] getEmails() {
return m_emails;
public void setEmails(String[] emails) {
m_emails = emails;
}But this will:
public class EmailBean {
private Email[] m_emails;
public EmailBean() {
m_emails = new Email[] {
new Email("[email protected]"),
new Email("[email protected]"),
new Email("[email protected]")
public Email[] getEmails() {
return m_emails;
public void setEmails(Email[] emails) {
m_emails = emails;
}public class Email {
private String email;
public Email(String email) {
this.email = email;
public String getEmail() {
return email;
public void setEmail(String email) {
this.email = email;
}For the one that uses the Email class, I use this:
<h:dataTable value="#{emailTestBean.emails}"
var="email">
<h:column>
<f:facet name="header">
<h:outputText value="Email Address" />
</f:facet>
<h:inputText value="#{email.email}" />
</h:column>
<f:facet name="footer">
<h:commandButton value="Submit" />
</f:facet>
</h:dataTable>Otherwise I don't need the extra ".email":
<h:dataTable value="#{emailTestBean.emails}"
var="email">
<h:column>
<f:facet name="header">
<h:outputText value="Email Address" />
</f:facet>
<h:inputText value="#{email}" />
</h:column>
<f:facet name="footer">
<h:commandButton value="Submit" />
</f:facet>

How to handle an array of strings in LabView is impatient.
I want to VB program implemented in LabView.Have you actually tried to right click on the according node parameter and select Create->Constant or Create-Control??
And I don't see any string array in the parameter list. That are all simple strings and the VB code in your first post clearly shows that the call to the function only indexes the first element of those arrays to be passed to the function, not the entire array.
If the function really reads arrays despite being declared as only taking strings then it is using some weirdo VB trickery and there will be no way to replicate that in LabVIEW.

How to return array of String to a java program.! ??
Hi All,
I am new to JNI programming. so trying with simple example. I am having one problem. I have one array of String in my Java program. I want to reverse all the elements in this array and want back this new array in the same form i.e. array of string. So how can I do this ??
Please guide me.....
The function of defination of array in my java code is
public native String[] getReverseStringArray(String[] arrString);
where as my array is like:
String[] arrStr = {"one", "two", "three", "four", "��������","�c��","�J�^�J�i"};
and I am calling function in C file like:
arrStr = employee.getReverseStringArray(arrStr);
and the function defination in my c file is
JNIEXPORT jobjectArray JNICALL
Java_Emp_getReverseStringArray (JNIEnv *env, jobject obj, jobjectArray arr)
// some code will come here......
So can anybody tell me how to do this ??
Thanx in advance...
Pandurang
[email protected]Hi,
this is quite simple. Here an example function that works like this:
JNIEXPORT jobjectArray JNICALL Java_cadagent_ugopen_UgAssembly_jni_1getStructure
(JNIEnv *env, jclass cls, jstring part)
jobjectArray retvals = NULL;
jstring j_val = NULL;
int child_count = 5;
/* initialize return array */
j_val = (*env)->NewStringUTF(env, "");
retvals = (*env)->NewObjectArray(env, child_count, (*env)->FindClass(env, "java/lang/String"), j_val);
for (i=0;i<child_count;i++)
j_val = (*env)->NewStringUTF(env, "some text");
(*env)->SetObjectArrayElement(env, retvals,i, j_val);
return retvals;
Hope this answers you question. -
Okay, my first concern is that I'm pretty new to Java. It's my first language that I've ever looked at, and I'm just getting into it.
I'm trying to read from a .txt file a name and an integer value associated with that name, like for instance, Jimmy Bob Jones 123. I have several lines of different names with different integers associated with each, sorted alphabetically in the .txt file to begin with. That's not the issue really--though I haven't figured out how to do that, I figure it's pretty simple compared to what I have to do with those. I set each line as a new element in an array of Strings, and then I want to sort them based on the value of the integer that follows each. I know that each integer is 5 digits, so I'm thinking about some way to sort based on Integer.parseInt(name.substring(name.length - 5, name.length)) for each element, but it's not coming to me.
I mean, let's say I have the following in a .txt file:
Abigail 32534
Bo 28935
Chris 45000
Damian 13777
And I feed those into my .class and set each line to an array element, so it would be like arrayName[0] = "Abigail 32534" etc. for each. Convoluted question, sorry. How would I sort those strings based solely on the integer values, yet also retain the name that goes along with it?
Any help is appreciated, though I don't guarantee I'll understand : )One easy (such a relative term) way is to create an Object, such as NameAndNumber, which has two member variables (name and number). When you read in your file, create objects of this type.
As for the sorting, this is a two step process:
1) Create a Comparator class to compare your objects
2) Populate a TreeSet which uses this comparator.
The TreeSet will be sorted automatically (based on your Comparator) and you can then iterate through it to retrieve instances of your object.
This all sounds much more complicated than it is. I have written some code to get you started.
// Your class
public class NameAndNumber {
private int m_nNumber;
private String m_sName;
// sets the name
public void setName(String sName) {
m_sName = sName;
// gets the name
public String getName() {
return m_sName;
// sets the number
public void setNumber(int nNumber) {
m_nNumber = nNumber;
// gets the number
public int getNumber() {
return m_nNumber;
// Your comparator
public class MyComparator implements Comparator {
// required by interface
public int compare(Object obj1, Object obj2) {
// throws ClassCastException if there is a problem - you will need to add
// handling if this is an issue
NameAndNumber objNan1 = (NameAndNumber) obj1;
NameAndNumber objNan2 = (NameAndNumber) obj2;
// will return the proper comparison based on the number
return (objNan1.getNumber() - objNan2.getNumber());
// Inside your "main" class
TreeSet setNumbers = new TreeSet(new MyComparator());
NameAndNumber objNameAndNumber = getNextListing(); // you need to provide this method, which gets the items one at a time
setNumbers.add(objNameAndNumber);Hope this helps. -
2 parts: 1) integer array to string 2) string out to a jTextField
I am completely new to Java and Netbeans, but I'm writing my 1st
application that takes a "hex" character input from a jTextField,
then converts it to an "binary" integer array. I then do a lot of bit
manipulation, and generate a new "binary" integer array.
String myhex = jTextField1.getText();
int len = myhex.length();
int[] binarray = new int[len*4];
for (int i = 0; i < len; i++) {
if (myhex.charAt(i) == '0'){
binarray[4*i]=0;
binarray[4*i+1]=0;
binarray[4*i+2]=0;
binarray[4*i+3]=0;
else if (myhex.charAt(i) ==
// repeat for '1 to 9' and 'a-f/A-F'
// generate new integer array(s) using various bits from binarrayI realize it might not be the best way to do the
conversion, but my input can be of arbitrary length,
and it is my first time trying to write Java code.
All of the above I've completed and it works...(thanks Netbeans
for making the gui interface design a real breeze!)
So I end up with:
binarray[0]=0 or 1
binarray[1]=0 or 1
binarray[2]=0 or 1
binarray[n]=0 or 1
Where n can be any number from 0 to 63...
I then manipulate the bits in binarray creating a new integer array
and for the sake of expediency let's call it "newbinarray".
newbinarray[0]=0 or 1
newbinarray[1]=0 or 1
newbinarray[2]=0 or 1
newbinarray[n]=0 or 1
Where n can be any number from 0 to 63...
I first need to know how to convert this "newbinarray" integer array to a string.
In the simplest terms if the first three elements of the array are [0][1][1],
I want the string to be 011.
Then I want to take this newly formed string and output it to a jTextField.
string 011 output in JTextField as 011
I've scoured the net, and I've seen a lot of complex answers involving
formatting, but I'm looking for just a simple answer here so I can finish
this application as quickly as possible.
Thanks,
Thorne KontosHere's an example, not using NetBeans:
import javax.swing.*;
public class TextDemo extends JPanel
public TextDemo()
int[] newbinarray = {0, 1, 1};
StringBuffer sb = new StringBuffer();
for (int value : newbinarray)
sb.append(value);
String st = new String(sb);
this.add(new JTextField(st));
private static void createAndShowGUI()
JFrame frame = new JFrame("TextDemo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new TextDemo());
frame.pack();
frame.setVisible(true);
public static void main(String[] args)

Get numerical values from 2D array of string
Hello!
I start by saying that I have a base knowledge of LabView. I'm using LabView 2011. I'm doing some communications test via Can-Bus protocol. As you can see in pictures of the block diagram and of the front panel that I've attached I'm using "Transmit Receive same Port" LabView example. It works very good but I would need to insert the 8 data bytes that I receive from the server in 8 different numerical variables so that I could use them to make some operations. How can I get numerical values from the 2D array of string that I attached?
Every example that you can provide is important!
Thank you very much!

How do I write an array of strings to a single Excel row?
I'd like to write test data, as an array of strings, to an Excel file. Attached is my attempt to modify one of the Labview 6.1 example files. This modified example will write the data to the correct row, which is determined by serial # of the UUT, but to a new sheet for each unit. I'd like to do the same thing, but to just one sheet. This sheet's data would then be saved after 50 rows of collected test data.
Thank you in advance,
Tim Denson

Write Table To XL.vi 58 KBSorry I didn't get back to faster on this. I've been out of town working and just really haven't had time.
Yes,
The Report Generation toolkit would make this very easy. If you have it, I'd suggest using it.
The image shown below shows the five VIs from the toolkit that I've used to write to Excel.
What this loop does is receive a string through a Queue, either open a
template or open todays file, convert the tab delimited string to an
array, write the array to the next line of the Excel file, Save (with
todays date stamp if opened from the tempate) and close it. It's a good
idea to always save and close teh file after each write if it's not
being continuously written to. In this case, a new line will be written
only once a minute or so. This lessens the chance of losing data if the
machine locks up for some reason. Opening and closing does take time
and can slow down a loop that needs to run at a certain rate. This loop
actually runs in a background process and several other processes send
data to it through the queue to be written. The queue can buffer
several data streams if needed so you won't lose data if it's busy and
you don't have to worry about two processes accessing the Excel sheet
at the same time.

Problem in converting vector to array of strings
hi
i am having a vector which in turn contains hashtable as elements
Vector v=new Vector()
Hashtable ht=new Hashtable();
v.add(ht.add("key1",value1))
v.add(ht.add("key2",value2))
v.add(ht.add("key3",value3))
v.add(ht.add("key4",value4))now i am trying to conver this vector in to a array of string like
String[] str=(String[])v.toArray(new String[v.size()]);but i am getting java.lang.ArrayStoreExceptioncan anybody help me plz
ThanksHi,
The api for public Object[] toArray(Object[] a) says
Returns an array containing all of the elements in this Vector in the correct order; the runtime type of the returned array is that of the specified array.
ArrayStoreException will be thrown if the runtime type of a is not a supertype of the runtime type of every element in this Vector.
The runtime type of the elements of the vector is Hashtable.
Because String is not a supertype of Hashtable the ArrayStoreException is thrown. -
[CS3][JS] How to turn negative number in array into string
Hello,
I have a script that compares the array of the geometric bounds of all text frames to the margins for a document (all pages having the same margins). Any frames that do not match the margins are flagged.
In order to compare the array of text frame geometric bounds to two arrays of margins (because they are facing pages), I have to convert the numbers to strings.
My problem is that in the following snippet of code that creates the two margin arrays, the negative of the variables become numbers again. This would not be too difficult to solve except that all the numbers have to be 4 decimal points before converted to strings.
Thanks,
Tom
var myDoc = app.activeDocument;
var marginY1 = myDoc.pages.item(0).marginPreferences.top.toFixed(4);
var marginX1 = myDoc.pages.item(0).marginPreferences.left.toFixed(4);
var marginY2 = (myDoc.documentPreferences.pageHeight - myDoc.pages.item(0).marginPreferences.bottom).toFixed(4);
var marginX2 = (myDoc.documentPreferences.pageWidth - myDoc.pages.item(0).marginPreferences.right).toFixed(4);
var marginsRHand = [marginY1, marginX1, marginY2, marginX2];
var marginsLHand = [marginY1, -marginX2, marginY2, -marginX1];Well, I think I have solved it. But I don't know why this solves it.
I would think that in the above script all the variables would be numbers and not strings. But the data browser says they are strings.
The solution is:
var marginsLHand = [marginY1, Number(-marginX2).toFixed(4), marginY2, Number(-marginX1).toFixed(4)]
If someone can explain why now all variables in the arrays are strings and not numbers, I'll be happy.

Mapping lookup up failure with input JavaBean with an array of strings
To receive input data our Web service defines a JavaBean one element of which is
an array of strings. When a test Java client calls the service method the call
is completed successfully. When a Perl client calls the service method an exception
is returned. If I understand BEA's Web service documentation, it isn't necessary
to do development for the service specifically to enable correct processing of
an array of strings.
In our environment we are running WL 8.1 SP 1.
Please review the problem documentation and explain to me the cause of the exception
and what I must do to prevent it.

</project>Hi Jeff,
Looks like the Perl client is using an older (deprecated) schema
namespace "http://www.w3.org/1999/XMLSchema" that is causing this
failure.
Hope this helps,
Bruce

To receive input data our Web service defines a JavaBean one element of which is
an array of strings. When a test Java client calls the service method the call
is completed successfully. When a Perl client calls the service method an exception
is returned. If I understand BEA's Web service documentation, it isn't necessary
to do development for the service specifically to enable correct processing of
an array of strings.
In our environment we are running WL 8.1 SP 1.
Please review the problem documentation and explain to me the cause of the exception
and what I must do to prevent it.
Thank you.

Array of strings strict type def not updating
I have defined an Array of Strings (ctrl) as a strict type def. When I update this array (add another string to it) the values don't update where this control is used. Can someone please explain why this is occuring.
Only the size of the array _shell_ is locked, not the size of the array data. The array shell is a window into the data of the array control. If you change the value of the index display you will change the indices visible inside the array shell.
