How to index occurrences in the array

Hi Is there a way how we can index each occurrence in the array?
It seems that search ID Array is once and I cannot figure out how to do it.
Please advise
Thanks in advance

Solved!
Go to Solution.

Do you need only the indexes that matches the search element like this?
The best solution is the one you find it by yourself

How do you check if a array is full?

suppose you have a array of hmm numbers.
How would you test if the array is full?

What do you mean with "full"? It depends on your definition. There isn't such a thing as an "empty" array. It's values might be null and depending on your definition that might mean "empty", but it might as well not. Usually if you create an array that's bigger than the amount of storage you need right now (for example to avoid re-allocating it later on) you'll also keep another variable that tells you up to which position you already filled it:
int[] myArray;
int position;
public addInt(int value) {
if (position >= myArray.length) {
throw new ArrayFullException();
myArray[position++]=value;
}

How do I create a 1d array that takes a single calculation and insert the result into the first row and then the next calculation the next time the loop passes that point and puts the results in thsecond row and so on until the loop is exited.

The attached file is work inprogress, with some dummy data sp that I can test it out without having to connect to equipment.
The second tab is the one that I am having the problem with. the output array from the replace element appears to be starting at the index position of 1 rather than 0 but that is ok it is still show that the new data is placed in incrementing element locations. However the main array that I am trying to build that is suppose to take each new calculation and place it in the next index(row) does not ap
pear to be working or at least I am not getting any indication on the inidcator.
Basically what I am attempting to do is is gather some pulses from adevice for a minute, place the results for a calculation, so that it displays then do the same again the next minute, but put these result in the next row and so on until the specifiied time has expired and the loop exits. I need to have all results displayed and keep building the array(display until, the end of the test)Eventually I will have to include a min max section that displays the min and max values calculated, but that should be easy with the min max function.Actually I thought this should have been easy but, I gues I can not see the forest through the trees. Can any one help to slear this up for me.

I didn't really have time to dig in and understand your program in depth,
but I have a few tips for you that might things a bit easier:
- You use local variables excessively which really complicates things. Try
not to use them and it will make your life easier.
- If you flowchart the design (very similar to a dataflow diagram, keep in
mind!) you want to gather data, calculate a value from that data, store the
calculation in an array, and loop while the time is in a certain range. So
theres really not much need for a sequence as long as you get rid of the
local variables (sequences also complicate things)
- You loop again if timepassed+1 is still less than some constant. Rather
than messing with locals it seems so much easier to use a shiftregister (if
absolutely necessary) or in this case base it upon the number of iterations
of the loop. In this case it looks like "time passed" is the same thing as
the number of loop iterations, but I didn't check closely. There's an i
terminal in your whileloop to read for the number of iterations.
- After having simplified your design by eliminating unnecessary sequence
and local variables, you should be able to draw out the labview diagram.
Don't try to use the "insert into array" vis since theres no need. Each
iteration of your loop calculates a number which goes into the next position
of the array right? Pass your result outside the loop, and enable indexing
on the terminal so Labview automatically generates the array for you. If
your calculation is a function of previous data, then use a shift register
to keep previous values around.
I wish you luck. Post again if you have any questions. Without a more
detailed understanding of your task at hand it's kind of hard to post actual
code suggestions for you.

How can I return to the top of an array indicator

I have in my UI a 1D array indicator that I will navigate to and populate with different lists of items depending on other selections. Always text elements.
I have limited the number of visible rows to 20 max even though some lists will contain dozens if not hundreds of elements while others may have less than 10. Problem is, if I scroll down the list for one population, then come back and the next list happens to have only 10 elements, the scroll bar is still way down where I had scrolled to earlier. It is basically showing unpopulated positions in the array. (Not blank list items)
How can I return the scroll position back up to the first element in the array when I populate it with a new list? I looked through every property node and could find nothing. Seems like there should be a method to refresh the display or it should go back to the top when you write a new value to it.
Any thoughts?
Thanks
Doug

Index Values, I think, is the property you are looking for. Set the index to 0 to be at the top.

How do I insert into an array only if the condition is true?

I am buiding an array made up of pairs of data from a file. I am going through line by line putting the values in an array and then taking the pairs of two indexes oring them and putting the number into another array. I do not know if there is more than one set on each line so I have to do a while loop to check.The problem is I have to get the indexes in pairs, so for example I take in the element from index 0 and 1 and or them index 2 and 3 and or them, I do not need the combination of 1 and 2 or 3 and 4 and etc. I am using the "Quotient & Remainder" to check if the index is even or odd, if it is even I take that element and the very next index's element, I or them and put them in another array, but if i
t is odd I do not want to put anything into the array. How can I go about doing that? Any help would be appreciated. I am using version 6.1 Thanks, Molly

Molly,
Rather than running while loop which only executes code every other time you could instead just do a little more math to get your index values. Just multiply the iterator (i) terminal by 2 for the first index and then add 1 to it for the second (you'd need to run the loop half as many times of course). This would be more efficient and easier to read in your code. One other tip is that when you are running a loop a specified number of times it's cleaner to use a for loop rather than a while loop.

How to use the array elements

Hi, i'm trying to automate a questionary using array.
// In the compositionReady for the stage
sym.actual = 0;
sym.arr = [ "Hi","Love","You" ]              // This is my question array.
sym.checkArr = function(){                  // this the function that i use to check whis question of the array i'm going to use.
          sym.Question = arr[actual];      // i want to use the value "Hi", and then increase my "actual" var and then use the value "Love"
// In my symbol timeline i use a trigger, in that trigger i use
sym.stop();
sym.quest = sym.getComposition().getStage().Question;         // I'm getting the Question value;
sym.$("Ask").html(quest );                                                         //"Ask" is an empty textfield;
sym.getComposition().getStage().actual ++;                    // Increase "actual" for the nex time.
But the code doesn't work, i think the problem is the way i use the array index.
Please help!
Thanks =)

Hi there,
chino_10 wrote:
in te timeline trigger why did you use a local variable?
It's good practice to use local variables whenever possible. The quest variable will only apply to that trigger, and it won't carry over to another trigger in the same timeline. So when using a trigger to set the HTML of a text element in the same timeline, I find it cleaner to assign a new HTML value from a local variable.
chino_10 wrote:
and if you are calling the global variable "actual" from de compositionReady handler why didn'y you call it with all the path like "sym.getComposition().getStage().actual ++;"?
I think maybe I didn't express it as clearly as I could have. When you declare sym.actual in compositionReady, you actually have declared a variable scoped to the main stage symbol - it's not a global variable. To declare a global variable (which is not always best practice), your code in compositionReady would be:
actual = 0;
This actual variable would now be accessible from any element/symbol in the composition simply by assigning a value to actual. You may see how this could quickly get messy.
So getting back to variable scope: if you declare a symbol variable using sym.varName, then any element in the same scope can call it using sym.varName. So your main timeline triggers can call it without using the full addressing of sym.getComposition().getStage().actual++. Instead, you could just use sym.actual++. Less code, and easier to read. But if you wanted to call it from another symbol (outside of the scope of the main stage), then you'd have to use the full addressing to actually address the variable, i.e., sym.getComposition().getStage().actual ++.

How to find and display the posistion in an array list

hi all,
i know this is proballly simple but i have an arraylist where every time someone connects to my system it adds them to an arraylist, how can i post back somelike like hi user "1" thanks for connecting and so on. i just dont understand how to find their unique posistion in the array list and display it as a number.
any help would be great

So to be clear...
You have an arraylist of connections .... for example
ArrayList<ConnectedPeople> connPplArr = new ArrayList();And then each time someone connects you would add a connected people object to the arraylist.
ConnectedPeople, migh contain username etc etc.
You could then do:
ConnectedPeople newConnection..... ;
int index = connPplArr.indexOf( newConnection );
if(int == -1){
add them to your array
index = connPplArr.size();
return "Hello user "+ index;That what you mean?
I know some of it is sudo code, but have I understood your problem?

How to update a chart when the array is updated

                       negative += 1;

Sorry, in my app I have an ArrayCollection of items from a news feed that the user has deemed important, and given each item a rating. The For loop will loop through the "newsDB" array and set the var accordingly (positive, negative, neutral). The variables are what is populating the arrayCollection (ratingAC). How would I either a) bind the variables to the ArrayCollection so that it updates when one has changed, or b) update the specific index in the array collection. When debugging, i notice that the variables are updating, but the arrayCollection is not.
Thanks in advance!

How can I perform the LINEST function using the new version of Numbers? The old method of using "command enter" to complete the array function does not work. Please help ASAP!!!

LINEST function using Numbers for Mac

Thank you for your help. This page is somewhat helpful, but I still don't quite understand. I am using the Numbers program, and my assignment calls for me to use the LINEST function to return a set of 10 values.
When I googled how to do this, a lot of pages mentioned hitting "command+enter" to complete the array function, but they were using an older version of Numbers and it doesn't do anything when I try it in the new version. I tried using "Index" with LINEST, and i've managed to get about 5 values out of it.

How can I get all the values of a String array profile property using javascript?

I am trying to build functionality into our site that records all products added to the basket against a user's profile.
I have so far been able to store the product codes against the profile as a property using Ajax:
       var dataString = ":formid=addProduct&:formstart=/apps/thread/templates/page_product/jcr:content/par/produc t/formstart&:redirect=/content/thread/en/user/cart.html&productId=151515:profile="+profile ;
                     $.ajax({
            type: "POST",
            url: "/content/women/evening/dresses/l-k-bennett-davinadress.html",
            data: dataString,
            success: function(data) {
In this example I have hardcoded a product ID of 151515.
In order to save the property as a multi string field you simply replace &productId=151515 with &productId=151515&productId=131313&productId=141414 or as many extra values as you want to build into that string. This stores a productId property against a user profile.
The issue comes from calling that data back. Using var value = CQ_Analytics.ProfileDataMgr.getProperty("productId") I can get the first value of this array (or the single value if only one is stored).
However there does not seem to be a way to get any of the other stored values in the array using getProperty. Does anyone know how I can achieve this?

Hi,
Don't think that's possible. Even if it were, you wouldn't be able to use/display BOOLEAN type in SQL.
If you just aim to see what they are, you could do something like this
select text
from all_source
where owner = 'SYS'
   and name = 'DBMS_DB_VERSION'
   and type = 'PACKAGE';Or even
select dbms_metadata.get_ddl('PACKAGE', 'DBMS_DB_VERSION', 'SYS') from dual;My version is:
SQL> select * from v$version where rownum = 1;

How do I get a byte array from an object passed into the JNI?

This is what my java code looks like:
public class streamedData
protected byte[] m_value = null;
public byte[] getByteArray ()
return m_value;
/* code not pertaining to this question snipped. */
jclass streamedDataClass = env->GetObjectClass(jstreamedData);
// Get methodIDs for the various NPKI_Extension methods
value = env->GetMethodID(streamedDataClass, "getByteArray", "()[B");
lstreamedData->value = (unsigned char *)malloc (lstreamedData->length);
if (lstreamedData->value == NULL)
return INSUFFICIENT_MEMORY;
memset (lstreamedData->value, 0, lstreamedData->length);
memcpy (lstreamedData->value, env->CallByteMethodA(streamedDataClass, value, NULL), lstreamedData->length);
This is not working.
My question is, how do I get a copy of or read m_value in the JNI layer? Do I have to make the byte array public and access it as a field ID?
Any help would be appreciated. Why oh why can't there be a CallByteArrayMethod????

My question is, how do I get a copy of or read m_value in the JNI layer? Do I have to make the byte array public and access it as a field ID?
You can retrieve a handle to the byte array, through a method call, as you're doing now, or by directly accessing it through GetFieldID.
In the case of the method call, you'll want to do:jmethodID getByteArrayMethod = env->GetMethodID(streamedDataClass, "getByteArray", "()[B");
jbyteArray byteArray = static_cast<jbyteArray>( env->CallObjectMethod( jstreamedData, getByteArrayMethod ) );In the case of field access, you can do:jfieldID m_valueFieldID = env->GetFieldID( streamedDataClass, "m_value", "[B" );
jbyteArray byteArray = static_cast<jbyteArray>( env->GetObjectField( jstreamedData, m_valueFieldID ) );Once you have byteArray, you need to access it using the array operations:lstreamedData->value = env->GetByteArrayElements( byteArray, 0 );
// Do what you want to do, then release the array
env->ReleaseByteArrayElements( byteArray, lstreamedData->value, 0 );As always, Jace, http://jace.reyelts.com/jace, makes this easier. For example,void printByteArray( jobject jstreamedData ) {
streamedData data( jstreamedData );
JArray<JByte> byteArray = streamedData.m_value();
for ( int i = 0; i < byteArray.length(); ++i ) {
cout << byteArray[ i ];
}God bless,

How can I, depending on the elemnts of an array, write into the same array

Hi everyone, to make this a little clearer, consider a 2*2 I8 array, many y objective is the following:
1) connect the array to the case structure, and depending on a specific case that's value of element of indeces (0,0), write over the same array in this way
1 0
2 3
for example, note that in (0,0) there's 1, so my decision is to make the array (same array) as:
0 0
2 3
any ideas?
Thanks.

The array data is in the shift register or wire!
Any controls or indicators of the array just lets you interface to it via the front panel. Don't use controls or indicators as data storage via local variables, that's not the right way.
Here's a very simple demo (LV 8.0) that shows one possibility how to do this. See if it makes sense.

How to put data into a array element in the BPEL

Hi,
I have a element in the WSDL which is of type Array. (i.e accepts unlimited data for the same element). How should i put a data into a array in the BPEL.
Example:
The below Example gives u an idea about wht iam asking:pasting a piece of my requirement:
<s:element minOccurs="0" maxOccurs="1" name="parameters" type="tns:ArrayOfCSParameters" />
<s:complexType name="ArrayOfCSParameters">
<s:sequence>
<s:element minOccurs="0" maxOccurs="unbounded"
name="CSParameters" nillable="true" type="tns:CSParameters" />
</s:sequence>
</s:complexType>
<s:complexType name="CSParameters">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="RevenueItem" type="tns:RevenueItem" />
<s:element minOccurs="0" maxOccurs="1" name="AccountURIs" type="tns:ArrayOfString" />
<s:element minOccurs="0" maxOccurs="1" name="GroupURIs" type="tns:ArrayOfString" />
<s:element minOccurs="1" maxOccurs="1" name="Percentage" nillable="true" type="s:decimal" />
</s:sequence>
<s:attribute name="Version" type="s:decimal" use="required" />
<s:attribute name="URI" type="s:string" />
</s:complexType>
Any suggestion is appreciated.

You have 2 options i guess.
Use the transformation and the for-each to construct the array-list
or like Richard said, use a loop in bpel, assign in the loop an variable of element type="CSParameters" and append this variable to your variable with accepts the arraylist.
