Source array to desination array
i have a method that is meant to copy all numbers in the source array (src) to the destination array (dest). I have developed the following but unsure if it is right.
TASK: copying all numbers in the source array (src) to the destination array (dest)
private void copyToTemp(int[] dest, in[] src)
int[] src = {1, 2, 3, 4 , 5};
int[] dst = new int[10]
System.array(src, 2, dst, 0, 7);
console.printf(new String(dst));
}

Can anybody tell me how to create pointers in an array pointing to other arrays?

Hi tbob,
thanks for your suggestion! I did build it up with three arrays and a numeric control to select one of the arrays, which works fine. However, there are the following effects which I don't understand yet.
1. The RefArray can only be defined as Variant, showing a violet colour instead of a green/blue as in your example; I could not find a refnumber without giving me an error.
2. By changing the array selector, following array elements are being written into: 1,1 of array0; 0,0 of array1 and 1,0 of array2. I don't see why it is different for each array. Is there a possibility to select the array element being written into?
My VI is attached, LV7.1
Kind regards
Richard
Strange, when I created my vi, the RefArray was blue-green, not a Variant. On the front panel I placed a blank array. Then I placed a Control Refnum into the array. Now the array is defined as a Control Refnum Array, not a Variant.
Attached is a vi similar to the picture I had previously attached. In your case, you would need a slightly different method because of your unknown quantities of channels for each source. The use would select a source, and then you would have to retrieve an array of channels for that source. The user then selects a channel, and you would have to retrieve the data for that channel.
Post what you have so far so that we can look at it.

Assigning javascript array with jsp array
hi,
I have a jsp page where I have a array in jsp. I want to assign the values to an javascipt array. how can I do that?
the reason why I want to do this is for a perticular problem I am facing in javascript. that is....
I have a text box in my jsp page, I want the value entered in that box to be checked (whether it exists ) against a hidden string which has some value. I want that hidden string not to be shown to the user even on seeing the html source. that is why I want these values to be stored and checked against a array object of javascript.
any suggestion is appreciated
Thanks

if you dont mind of viewing code u can use this else dont use, its not matters weatehr user will see you code or not if the user is professiona then its a big issue normal users not think of is for this dont send valuable infos like password etc to client u may send usernames
ok to create a java array to javascript array do this (i took example of db to array ) write this inside <script> <%codes here%> </script>
var aUsername =new array();
<%
int i=0;
while (rs.next())
%>
aUsername[<%= ++i%>] = "<%= rs.getString("User_Name")%>";
<%
%>thats it use this array where ever you want in your client side(javascript ) usage
hope this will help you

Can't duplicate movieclips as an array within an array
Hello.
I have an animation that loads an xml into it and traces back
an array within an array. I have tried to apply this to duplicated
movieclips thereby creating a structured set of links. What I am
trying to do is this:
Chicken Nuggets
__Compression
__Texture
__Disgust
Mega Warhead
__Taste
__Hardness
__Pain
This traces fine but I can't seem to get the duplicated
movieclips to assemble in this fashion.
The code for the XML is as follows:
var controlArray:Array;
var variable:Array;
var testTopic = new Array ();
var test = new Array ();
var controlsXML:XML = new XML();
controlsXML.ignoreWhite = true;
controlsXML.onLoad = function(success:Boolean){
if (success){
var mainnode:XMLNode = controlsXML.firstChild;
var controlNodes:Array =
controlsXML.firstChild.firstChild.firstChild.firstChild.childNodes;
var list:Array = new Array();
for (var i:Number = 0; i < controlNodes.length; i++) {
var personnode:XMLNode = controlNodes
.attributes.Name;
trace(personnode);
testTopic.push (new struct (personnode));
var specificNode:Array = controlNodes.childNodes;
for (var j:Number = 0; j < specificNode.length; j++){
var itemnode:XMLNode = specificNode[j].attributes.Variable;
trace(itemnode);
test.push (new struct2 (itemnode));
printer ();
printer2 ();
} else {
trace('error reading XML');
controlsXML.load ("controls3.xml");
The code for the movieclip duplication is as follows:
x = 50;
function printer ()
for (m = 0; m < testTopic.length; m++)
duplicateMovieClip ( slotTopic, "slotTopic" + m, m );
slotTopic = eval ( "slotTopic" + m );
slotTopic._y += x;
slotTopic.slotTopicContent.text = testTopic[m].personnode;
function printer2 ()
for (k = 0; k < test.length; k++)
duplicateMovieClip ( slot, "slot" + k, k );
slot = eval ( "slot" + k );
slot._y += x;
slot.slotContent.text = test[k].itemnode;
function struct (personnode)
this.personnode = personnode;
function struct2 (itemnode)
this.itemnode = itemnode;
On the stage are two movieclips, titled "slotTopic" and
"slot". Within those are dynamic text boxes titled respectively
"slotTopicContent" and "slotContent". When I preview this file it
only displays the text within the "slot" movieclip and it lists all
six of the subtopics with no break. So, there are two dilemmas:
1) The movieclips won't duplicate into the structured set of
links that I want.
2) "slotTopic" is not displaying text at all.
If anyone has any advice, I'd really appreciate it.
Thx!ok, I'm sorry but there are quite a few things wrong here.
first though, when posting code please use the 'attach code'
button.
1) i can't imagine that you have a XML structure as deep as
your calling to or the need for it with the limited amount of
infomation your pulling, in addition your storing the info in
attributes, so I can't see how this would work, it may 'trace' out
the right text (somehow) but it's not getting into the arrays
properly.
2) you do not assign an attribute value to a XMLNode, and
then try to push it into an array.
3) you do not call a method (struct or struct2) using the
'new' operator. this is how you envoke a new 'class' instance.
4) do not use 'x' as a variable name as it is a reserved var
in flash, assigned to an Object instance.
5) the duplicateMovieClip() method needs to be called upon
the existing clip as in:
slotTopic.duplicateMovieClip('slotTopic'+m, m);
additionally you can pass the _y placement within the
initObject.
6) you do not need to use eval, it isn't doing anything here,
you will gain the correct path by calling duplicateMovieClip
correctly.
7) the reason why slotTopic is not being displayed at all is
because of the second loop, you are duplicating the clips
(incorrectly) into the same depths thereby replacing all of the
contents of the slotTopic depths previously constructed.
the solution to this problem is to construct both items with
the same loop but increament one of the depth assignments by a
specific number, in other words at depths much higher or at least
different, than that of the first element, as in:
slotTopic.duplicateMovieClip('slotTopic'+m, m, {_y:50});
slot.duplicateMovieClip('slot'+(m+100), m+100, {_y:50});
again I'm sorry man, but it will take some work to sort this
out. -

I agree, this looks inconsistent.

Make the index of both the array 0 then run your program.
Now horizontal array shows 4th element & vertical array shows 10th element.
What are you trying to say here? You are just repeating the instruction #1 on the front panel of the posted VI, then repeating what the image above already shows.

hi guys
is it posible to place one array inside another array?
something like
public double[] dblarray(int n)
double [] dbl2 = new double(n)
return dbl2;
public double[] dbl2array(int m,int n)
int n=10
double [] dbl2 = new dobule[m];
for(int i = o;i < m ; i++)
dbl1=dblarray(n)
if tryed it an it told me its wrong. does any one know how to do it or if it is posible since i come from ansi c i know this is posible in c but is it in java???
pleas help:)
thanks
jelielNo, it's not possible in a strict sense. Java is more type safe than C - in C there is no real array type...
What you can have is an array of references (=pointers) to arrays of doubles, or double[][], and what your code does is more commonly written asdouble[][] dbl2 = new dobule[m][10]; -
Cast Object Array to String Array.
When I try to cast an object array to string array an exception is thrown. How do I go about doing it?
Vector temp = new Vector();
Object[] array = temp.toArray();
String[] nonterms;
nonterms = (String[])array;
Thanks,
AllyTry this
import java.util.Vector;
public class Test
public static void main(String args[]) throws Exception
Vector v = new Vector();
v.add("a");
v.add("b");
v.add("c");
Object[] terms = v.toArray();
for(int i = 0; i < terms.length; i++)
System.out.println((String)terms);

Converting an array to an array collection
When converting an array to an array collection, is it good
practice to remove the original array? If so, how does one do
that?My 2 cents - I think it may be unnecessary. The garbage
collector should notice a lack of references to the original array
and delete it for you. -
How do I make an array of String Arrays, not knowing how big the array will be
or how big any of the arrays it contains will be at the time I create it?The size of an array is not dynamic, i.e. if you use an array, you must know its size at the time you create it.
Use one of the collection classes (like java.util.Vector or one of the implementation classes of java.util.List).

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.
Check the javadoc for more information : http://java.sun.com/j2se/1.3/docs/api/java/util/Collections.html

How to add an Array within an array?
Hi friends can any body guides me how to add array within array.
Actually i am getting Array from server side and i have to append one more node(Array) in same array and send it back to them.
here is the structure of my array that i am getting from server side.
temp = Array (@4445e09)
[0] = mx.utils.ObjectProxy (@4314821)
Mylanguages = Array (@4445b69)
[0] = Object (@449ac91)
Mylanguage = "English"
Mylanguage_code = "EN"
Mylanguage_id = "1"
selected = "Y"
length = 1
currentpage = "1"
definition_id = "20"
delete_record = "Y"
edit_record = "Y"
insert_record = "Y"
numberofpages = "1"
numberofrecords = "1"
object = Object (@4432449)
productgroups = Array (@43cea51)
type = null
uid = "111111"
length = 1
I have to add an array similar to like Mylanguages containing object which contain some info like some ids. and my array becomes
ttemp = Array (@4445e09)
[0] = mx.utils.ObjectProxy (@4314821)
Mylanguages = Array (@4445b69)

id= "10"
tempId= "100"
Mylanguage_id = "1"
length = 1
type = null
uid = "111111"
length = 1
please tell me how it possible.
Thanks in Advance
Regards
Vineet oshoHi Vineet,
You can simply add another Array as shown below:
for each(var obj:Object in temp)
obj.AddedNOde = YourNewArray;
By doing above NewArray is added to all the objects of temp Array.

Convert javascript array to java array
Is there any way possible to convert javascript array to java array?
if you will try to experiment a javascript array
putting it to a hidden element, it will be converted
to a string (comma delimited). You can get the value
of that element as a string and use StringTokenizer
class to put the values into a java arrayThanks, got it. -
Hi, often I would love to index an array with an array of indexes or an array of booleans without having to loop it. I.e: let the IndexArray function accept an array of indexes instead of discrete indexes. The output should then be an array of indexes values.
Another use case is to index with an array of booleans, so each TRUE element would index the input array and FALSE elements are not indexed.
arrResult = arrInput[ arrIndexes ]; or
arrResult = arrInput[ arrVal > 20 ];
Would this be useful? Possibly it could be implemented in future versions?You forgot the link.
