Pagination with an array

Hello, i am trying to figure out how to create pagination with an array. I have done it before with a query but i can't seem to figure out how to do this with an array. Can someone please help me out with this?

I meant to say, its an array result set. I'm testing it with an array of 9 elements, and it knows that it should be 2 pages with 5 records each, but its expecting 10 results and i can't get it to work with 9.

How Do You Populate A Spark List Control With An Array?

Hello, all,
Sorry to come accross so frustrated, but how in the name of God do you populate a Spark list control with the data in an array? You used to be able to do this with the mx:List control, but the guys developing Flex just had to make things more difficult than they need to be! I am more of a code purist and prefer doing things the way they have been done for decades, but apparently nothing can ever stay simple!
I simply want to populate a list control with an array and this shouldn't be rocket science! I found out that I must use a "collection" element, so I decided that an arrayCollection would be best. However, after searching Adobe's documentation about arrayCollections, I am lost in a black hole of data binding, extra lines of code just to add a new element, the need to sort it, etc...!
Here is my code:
var pendingArray:ArrayCollection = new ArrayCollection();
for ( var i:int = 0 ; i < queue.length ; i++ )
     var item:UserQueueItem = queue[i] as UserQueueItem ;
     if ( item.status == UserQueueItem.STATUS_PENDING )
     pendingArray.addItem({label:item.descriptor.displayName,descriptor:item.descriptor});
Here is the relevant MXML:
<s:VGroup>
     <s:List id="knockingList" width="110" height="100"/>
</s:VGroup>
I'm not getting any errors, but the list is not populating.
I have seen several examples where the arrayCollection is declared and populated in MXML:
        <mx:ArrayCollection id="myAC">
            
            <fx:Array id="myArray">
                <fx:Object label="MI" data="Lansing"/>
                <fx:Object label="MO" data="Jefferson City"/>
                <fx:Object label="MA" data="Boston"/>
                etc...
           </fx:Array>
        </mx:ArrayCollection>
That may be fine for an example, but I think this is a rare situation. Most of the time I would image that the arrayCollection would be created and populated on the fly in ActionScript! How can I do this?
Thanks in advance for any help or advice anyone can give!
Matt

In your post it seemed like you were trying to take care of many considerations at once: optimization, design, architecture. I would suggest you get something up and running and then worry about everything else.
If I use data binding, then I will probably have to declare the arrayCollection as a global variable and then I'll have to write 100 or so extra lines of code to addItem(), removeItem(), sort(), etc... It just seems like too much overhead.
I believe you may have some misconceptions about databinding in general. You won't have to make it a global variable and you certainly won't need an extra 100 lines of code. If you did this forum would be a very , very quiet place.
I don't want to use data binding because the original array is refreshed often and there is one function called by an event that re-declares the arrayCollection each time, populates it with the array, and then sets it as the list's dataprovider.
That is the beauty of the ArrayCollection, it can handle the updates to its source Array. I don't know if you need to redeclare the ArrayCollection, resetting the source to the new Array allows everyone involved to keep their references so you don't have to worry about any "spooky" stuff going on.

Help with parallel arrays of different data types

Hello all, I am having an issue with parallel arrays. My program requires me to read information from a text file into 4 parallel arrays (2 String and 2 double). My text file needs to look something like this:
John Johnson
0000004738294961
502.67
1000.000
Jane Smith
0000005296847913
284.51
1000.000
...and so on
Where the first thing is the name (obviously), an account number, the balance in the account, and the credit limit. I just cant figure out how to read everything into the arrays. We havent learned anything too heavy, and this seems a little too advanced for my class, but I guess we will manage. Any help will be appreciated. Thanks guys.
Casey

Man this is a dumb homework assignment. The requirements scream out for a class along the lines of
public class Account{
private String name, number;
private double balance,creditlimit;
// more code here
}and then to use a List of Account objects.
Anyway what's your actual problem. There's nothing very hard about it. A loop. So....
You should consider posting (formatted) code showing what you have done and where exactly you are stuck.

Performance Problems with intrinsic array multiplikation in Fortran with Su

Hello,
I found a serious performance problem in my application with intrinsic array multiplikation. Therefore I wrote a small test program to check if this a general problem or only exists in my code.
The test program (as seen below) was compiled with Sunstudio12 und Solaris 5.10 on an 64 bit Amd Opteron Machine. First with high optimization (f95 -fast -g), and the second time with out optimization (f95 -O0 -g). In both cases the intrinsic array mupltiplication had a lot of tlb and L2 cache misses (I made some test with the performance analyzer) which caused a huge increase in computation time compared to the explicit loop. In the ideal case the compiler should create the nested loops from the intrinsic statement and both functions should use exactly the same computing time.
I also tried compiling with Studio11, the problem also occurs there. Maybe its a compiler bug but I'm not sure.
Greetings
Michael Kroeger

do j=0,nj
do i=0,ni
check2(i,j,k)=check2(i,j,k)*5
enddo
enddo
enddo
end subroutine withloop
end program

I will try the large pages, but what me puzzles is, that the intrinsic function has cache misses, but the loop function has not. All documentation says, that the compiler would expand the intrinsic function into 3 nested loops, so that both functions should be essential the same (and the compiler says it has created 3 loops from the intrinsic). Since they are not the same, this is a severe problem.
I have a fairly large code for high performance simulations, and this intrinsic functions are a significant bottle neck. If it is not a compiler bug, I would have to rewrite all intrinsic functions into loops.

Trouble with primitive arrays and casting, lesson 521

hi everyone!
there is a problem i discovered right now - after years with java where was no necessity to do this.....
and i'm shure this must have been the topic already, but i couldn't find any helpful resource :-/
right here we go:
1. an array is a (special) kind of object.
2. there are "primitive" arrays and such containing references to objects. of course - and i imagine why - they are treated differently by the VM.
3. then both are - somehow - subclasses of Object. whereas primitive types are not really, primitive-arrays are. this is hidden to the programmer....
4. any array can be "pointed" at via local Object variable, like this:
Object xyz = new int[6];
5. arrays of Objects (with different dimensions) can be casted, like this:
Object pointer = null;
Object[]   o = new SomeClass[42] ;
Object[][] oo = new OtherClass[23] [2] ;
Object[][][] ooo = new OtherClass[23] [2] [9] ;
o = oo = ooo;     // this is save to do,
                               //because "n-dimensional" object-arrays
                              // are just arrays of other arrays, down to simple array
pointer = o;         // ok, we are referencing o via Object "pointer"6. but, you cannot do this with primitive types:
int[] i1 = new int [99] ;
int[][] i2 = new int [1] [3] ;
i1 = i2                  // terror: impossible. this is awful, if you ask me.
                               // ok, one could talk about "special cases" and
                               // "the way the VM works", but this is not of interest to me as
                               // a programmer. i'm not happy with that array-mess!
pointer = i2;       // now this is completely legal. i2, i1 etc is an object!7. after the preparation, let's get into my main trouble (you have the answer, i know!) :
suppose i have a class, with methods that should process ANY kind of object given. and - i don't know which. i only get it at runtime from an unknown source.
let's say: public void BlackBox( Object x );
inside, i know that there might be regular objects or arrays, and for this case i have some special hidden method, just for arrays... now try to find it out:
public void BlackBox( Object x )
if ( x == null)
       return;
   Class c = x.getClass();
   if ( c.isArray() )
          // call the array method if it's an array.........
          BlackBoxes(     (Object [] ) x );         // wait: this is a cast! and it WILL throw an exception, eventually!
          return;
   else
           DoSpecialStuffWith( x );
}ok ? now, to process any kind of array, the special method you cannot reach from outside:
private void BlackBoxes( Object[] xs )
   if ( xs != null )
        for ( Object x : xs )
             BlackBox( x );
// this will end up in some kind of recursion with more than one array-dimension, or when an Object[] has any other array as element!this approach is perfectly save when processing any (real) Object, array or "multi-dimensional" arrays of Objects.
but, you cannot use this with primitive type arrays.
using generics wouldn't help, because internally it is all downcasted to Object.
BlackBox( new Integer(3) ) ---- does work, using a wrapper class
BlackBox( new Integer[3] ) ----- yep!
BlackBox( 3 ) ---- even this!
BlackBox( new int[42] ) ---- bang! ClassCastException, Object[] != int[]
i'm stuck. i see no way to do this smoothly. i could write thousands of methods for each primitive array - BlackBox( int[] is ) etc. - but this wouldn't help. because i can't cast an int[][] to int[], i would also have to write countless methods for each dimension. and guess, how much there are?
suppose, i ultimately wrote thousands of possible primitive-type methods. it would be easy to undergo any of it, writing this:
BlackBox( (Object) new int[9] [9] );
the method-signature would again only fit to my first method, so the whole work is useless. i CAN cast an int[] to Object, but there seems no convenient way to get the real array out of Object - in a generic way.
i wonder, how do you write a serialisation-engine? and NO, i can't rely on "right usage" of my classes, i must assume the worst case...
any help appreciated!

thanks, brigand!
your code looks weird to me g and i think there's at least one false assumption: .length of a multidimensional array returns only the number of "top-level" subarrays. that means, every length of every subarray may vary. ;)
well i guess i figured it out, in some way:
an int is no Object;
int[ ] is an Object
the ComponentType of int [ ] is int
so, the ComponentType of an Object int[ ] is no Object, thus it cannot be casted to Object.
but the ComponentType of int [ ] [ ] IS Object, because it is int [ ] !
so every method which expects Object[], will work fine with int[ ] [ ] !!
now, you only need special treatment for 1-dimensional primitive arrays:
i wrote some code, which prints me everything of everything:
    //this method generates tabs for indentation
    static String Pre( int depth)
         StringBuilder pre = new StringBuilder();
         for ( int i = 0; i < depth; i++)
              pre.append( "\t" );
         return pre.toString();
    //top-level acces for any Object
    static void Print( Object t)
         Print ( t, 0);
    //the same, but with indentation depth
    static void Print( Object t, int depth)
        if ( t != null )
             //be shure it is treated exactly as the class it represents, not any downcast
             t = t.getClass().cast( t );
            if ( t.getClass().isArray() )
                 //special treatment for int[]
                 if ( t instanceof int[])
                      Print( (int[]) t, depth);
                 // everything else can be Object[] !
                 else
                      Print( (Object[]) t, depth );
                 return;
            else
                System.out.println( Pre(depth) + " [ single object:] " + t.toString() );
        else
            System.out.println( Pre(depth) + "[null!]");
    // now top-level print for any array of Objects
    static void Print( Object [] o)
         Print( o, 0 );
    // the same with indentation
    static void Print( Object [] o, int depth)
        System.out.println( Pre(depth) + "array object " + o.toString() );
        for ( Object so : o )
                Print( so, depth + 1 );
    //the last 2 methods are only for int[] !
    static void Print( int[] is)
         Print( is, 0 );
    static void Print( int[] is, int depth)
        System.out.println( Pre(depth) + "primitive array object " + is.toString() );
        // use the same one-Object method as every other Object!
        for ( int i : is)
             Print ( i, depth + 1 );
        System.out.println( "-----------------------------" );
    }now, calling it with
Print ( (int) 4 );
Print ( new int[] {1,2,3} );
Print( new int[][] {{1,2,3}, {4,5,6}} );
Print( new int[][][] {{{1,2,3}, {4,5,6}} , {{7,8,9}, {10,11,12}}, {{13,14,15}, {16,17,18}} } );
Print( (Object) (new int[][][][] {{{{99}}}} ) );
produces this fine array-tree:

Change properties of a cluster element withing an array of clusters

Hello all,
I have an array of cluster that is shaped as a line with different display elements.
A list or a tree wouldn't have made it, so I had to use a cluster and make a table.
The problem is that I want to change not only the text but also the text color.
Individually.
I found this :
http://www.ni.com/example/30904/en/
But it change the property in all the clusters in the array, not just the one I need.
Some people have the same problem :

Obviously, while in a list/table or tree you can change the property of an individual
cell (font, color) you cannot do it within an array of cluster, by some sort of magic,
the property of a cluster element (font, color) are all linked together, hence rendering
the use of an array worthless.
A possible hack is proprosed by using control masking, setting one visible and the
other invisble, swapping their position, whatever. It's a hack you have to perform,
hence add another code to maintain.
Is that still the case or is there now a more official way to handle individual cluster
properties, not just its data ? After all that's a common real-life example that should
be handled by Labview. In my opinion.

One of the elements could be a 2D picture indicator of about the same size. You can write text in any color using picture functions.
Here's what I had in mind. Seems to work just fine (I would fine-tune the font, picture border, etc. but this should get you started).

Updating a JTable with an array of values

Ther is a constructor that allows for the cretion of the table with an iniital array of values. However subsequent updates of blocks of data- say you received an array of updated data form a database- reuiqre you to update ince cell at a time. Is ther any way fo updating a whole block at once. I should point out that I am asking this because I am using JTables in the Matlab programming environment where arrays are the basic unit and looping through is a comparatively slow process

Yes, you can extend the AbstractTableModel and write a method for updating a whole block.
lets say you've got a Vector with Float[] arrays as elements to hold a 2D array of Float. The you could write:
      TableModel dataModel = new AbstractTableModel() {
            public int getColumnCount() { return col_names.size(); }
            public int getRowCount() { return data.size();}
            public Object getValueAt(int row, int col) {
               return ((Float)((Float[])data.elementAt(row))[col]).toString();
            public String getColumnName(int col) {
             return ((String)col_names.elementAt(col));
            public Class getColumnClass(int col) {
             return String.class;
            public boolean isCellEditable(int row, int col) {
              return true;
            public void setValueAt(Object aValue, int row, int col) {
               try {
                 Float fv = Float.valueOf((String)aValue);
                ((Float[])data.elementAt(row))[col] = fv;
               } catch (Exception ex) {
            public void setBlock(Float block[][], int row, int col) {
               // copy the Arrays with System.arrayCopy into data
      };PS: I don't know, if the above is correct written, havn't test this. But I hope you can recognize the idea behind it.

Problem with an array (Array index out of bounds)

Hey guys, i have a problem with an array, i just want to print a few things but it won't let me because of this error, here's my code
     public static void MosDat()
          int i;
          for(i=0 ; i<n ; i++);
               Client [ i ].print1();
               Client [ i ].print2();
          return;
     }//MosDat
where "n" is a global variable, and client is .
I pretty much know how it woks, so i tried it like this and gave "n" the value of "1":
public static void MosDat()
          int i;
          for(i=0 ; i<n ; i++);
               Client [ 0 ].print1();
               Client [ 0 ].print2();
          return;
     }//MosDat
the printing methods i created worked prefectly when i tried it like that... so i really don't know where the problem could be... thanks anyone who can help me.

for(i=0 ; i < n ; i++);I spy with my little eye,
one semicolon too many.Well-spotted. ;-)Practicing on those weird question marks is my secret training.

Help with PHP array code

Not sure what's going on here, but hopefully someone can spot where I'm going wrong.
Its especially weird, as I'm using the same code, with the same database table names etc but on a different site.
Basically, I've set up a database table to store customer feedback on products.
Its all working fine on this site :
http://www.mye-reader.co.uk/customerreviews.php
But on the site I'm working on, its only showing the first record. There are only a couple of records at the moment, but I've tried changing the query from ASC to DESC, and it swaps the one it shows, so it looks like the issue is with the array. Even though its the same code.
http://www.mybabymonitors.co.uk/reviews.php
Anyway, my query looks like :
mysql_select_db($database_connPixelar, $connPixelar);
$query_rsReviews = "SELECT * FROM feedback WHERE Approved = 'Yes' ORDER BY Product DESC";
$rsReviews = mysql_query($query_rsReviews, $connPixelar) or die(mysql_error());
$row_rsReviews = mysql_fetch_assoc($rsReviews);
$totalRows_rsReviews = mysql_num_rows($rsReviews);
And the array code looks like :
<table cellpadding="0" cellspacing="0" width="100%" border="0">
       <?php
     $groups = array();
while ($row = mysql_fetch_assoc($rsReviews)) {
    $groups[$row['Product']][] = $row;
foreach ($groups as $product_name => $rows) {
    echo "<tr><td class=\"product\">$product_name</td></tr>";
    foreach ($rows as $row) {
        echo "<tr><td class=\"review\">".$row['Review']."</td></tr>";
        echo "<tr><td class=\"name\">".$row['CustomerName']."</td></tr>";
        echo "<tr><td class=\"date\">".$row['Date']."</td></tr>";
?>
</table>
Any ideas what's going on here?

Its OK - I figured it out - it was the
$row_rsReviews = mysql_fetch_assoc($rsReviews);
line in the query.
Turns out it wasn't that one was working, and the other not - they were both starting from the second record.

Using equals method with an array?

Hello all,
I am attempting to use the equals method with an array and keep getting compiling errors. Could you please take a look at my code and tell me where I am going wrong:
if(board[row][col].equals(" "))
          str=str + " ";
          else
          str=str + board[row][col];
Thank you.

Using a For Loop with an array

Ok, the issue is with the enabling of the buttons on my
stage. I run a loop to deactivate them all when one is clicked,
then I want to turn them back on, EXCEPT the one which was clicked.
I thought I could start off with an array of MC names and simply
delete them from the array. But I can't get my head around exactly
how to read in the array contents as MC names...
Any help would be greatly appreciated.

Try something like this:

Creating polygons with an array of doubles instead of ints

Hi,
I want to create a polygon using:
Polygon u = new Polygon(xPoints, yPoints, numTs);
my problem is that my x & y points are stored in double arrays not ints. Is there a way to create a polygon using double arrays instead of ints?
cheers,
elmicko

or cast them as int. imaginr posX, posY, width and height are doubles.
Rectangle rect = new Rectangle( (int)posX, (int)posY, (int)width,(int)height );or, with an array of doubles:
Rectangle rect = new Rectangle( (int)array[0], (int)array[1], (int)array[2],(int)array[3] );

There should be a way to index an array with an array of indexes or booleans (without a loop)

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?
