Array[1] vs array.GetItemAt(1)

Hello,
what is the difference between array[1] and array.GetItemAt(1)?
With [] Flash Builder tells me the databinding couldn't recognized any changes!? But why?
Thank you!

That's correct you can filter the output of the AC so it only shows by lastName or whatever database field you want.

How I can transfer data from the database into a variable (or array)?

I made my application according to the example (http://corlan.org/2009/06/12/working-in-flash-builder-4-with-flex-and-php/). Everything works fine. I changed one function to query the database - add the two parameters and get the value of the table in String format. A test operation shows that all is ok. If I want to display this value in the text area, I simply drag and drop service to this element in the design mode
(<s:TextArea x="153" y="435" id="nameText" text="{getDataMeanResult.lastResult[0].name}" width="296" height="89" />).
It also works fine, just a warning and encouraged to use ArrayCollection.getItemAt().
Now I want to send the value to a variable or array, but in both cases I get an error: TypeError: Error #1010: A term is undefined and has no properties..
How can I pass a value from the database into a variable? Thank you.
public var nameTemp:String;
getDataMeanResult.token = authors.getDataMean(arrayOfNumber[0], dir_id);
nameTemp = getDataMeanResult.lastResult[0].name;
public var nameArray:Array = new Array();
for (var i:uint=o; i<3; i++){
getDataMeanResult.token = authors.getDataMean(arrayOfNumber[i], dir_id);
nameArray[i] = getDataMeanResult.lastResult[0].name;
And how i can use syntax highlighting in this forum?

I have to go back to the discussion. The above example works fine when i want to get a single value of the database. But i need to pass an array and get an array, because i want to get at once all the values for all pictures tooltips. I rewrote the proposed Matt PHP-script and it works. However, i can not display the resulting array.
yep, it won't work for Arrays, you'll have to do something slightly more intelligent for them.
easiest way would be to get your PHP to generate XML, then read that into something like an ArrayList on your HTTPService result event (depends what you're doing with it).
for example, you could have the PHP generate XML such as:
<pictures>
     <location>test1.png</location>
     <location>test2.png</location>
     <location>test3.png</location>
     <location>test4.png</location>
     <location>test5.png</location>
     <location>test6.png</location>
</pictures>
then you'll read that in as the ResultEvent, and perform something like this on it
private var tempAC:ArrayList = new ArrayList
protected function getStuff_resultHandler(event:ResultEvent):void
    for each(var item:Object in event.result.pictures)
       var temp:String = (item.@location).toString();
       tempAC.addItem(temp);
in my example on cookies
http://www.mattlefevre.com/viewExample.php?tut=flash4PHP&proj=Using%20Cookies
you'll see an example of how to format an XML structure containing multiple values:
if($_COOKIE["firstName"])
        print "<stored>true</stored>";
        print "<userInfo>
                <firstName>".$_COOKIE["firstName"]."</firstName>
                <lastName>".$_COOKIE["lastName"]."</lastName>
                <userAge>".$_COOKIE["userAge"]."</userAge>
                <gender>".$_COOKIE["gender"]."</gender>
               </userInfo>";
    else
        print "<stored>false</stored>";
which i handle like so
if(event.result.stored == true)
                    entryPanel.title = "Welcome back " + event.result.userInfo.firstName + " " + event.result.userInfo.lastName;
                    firstName.text = event.result.userInfo.firstName;
                    lastName.text = event.result.userInfo.lastName;
                    userAge.value = event.result.userInfo.userAge;
                    userGender.selectedIndex = event.result.userInfo.gender;
depends on what type of Array you're after
from the sounds of it (with the mention of picture tooltips) you're trying to create a gallery with an image, and a tooltip.
so i'd probably adopt something like
<picture>
     <location>example1.png</location>
     <tooltip>tooltip for picture #1</tooltip>
</picture>
<picture>
     <location>example2.png</location>
     <tooltip>tooltip for picture #2</tooltip>
</picture>
<picture>
     <location>example3.png</location>
     <tooltip>tooltip for picture #3</tooltip>
</picture>
etc...
or
<picture location="example1.png" tooltip="tooltip for picture #1"/>
<picture location="example2.png" tooltip="tooltip for picture #2"/>
<picture location="example3.png" tooltip="tooltip for picture #3"/>
etc...

Multiple Comboboxes with single instance of Array Collection

First off - thanks to everyone for their contributions. This forum provides a lot of good information.
I'm stuck on a particular problem and I suspect I'm not thinking about the issue correctly.
I'm developing a dynamic module that instantiates components at runtime based on an XML scheme. Many of these components are drop-downs that are chained togther (a selection in one drives the population of the next)
I loop through the initial XML document to create and layout the components. I have been using a single Array Collection to populate the drop-down. This worked fine with the chained comboboxes since I only load one combox initially. However, when I add a couple of static combo boxes, the arraycollection seemed to be binding to the orginal combobox. For example, if I create 3 combo boxes they have drop-down values that display all 3 lists appended together. I was a bit surprised because I didn't think that I could bind an Array Collection. I certainly haven't defined a Binable ArrayCollection.
I thought I could solve the issue by simply creating a unique Array Collection at runtime - one for each element. However, I don't think this is possible or I can't figure out how to create a new Array Collection with a dynamic name - something like this:
I was hoping this would work -
var newDropDown_[numOfElement]:ArrayCollection = new ArrayCollection();
I've tried to use a Dictionary object to store each ArrayCollection. I couldn't get that to work properly.
Essentially - my code loops on the number of components to add:
for (var i:int = 0; i < numFormElements; i++)
          for (var j:int = 0; j < numvalues; j++)
                                var valuefield:String = 'value_' + [j+1];
                                var obj:Object=new Object();
                                obj.label=instFields[i][valuefield].@label;
                                obj.data=instFields[i][valuefield].@data;
                                newDropDown.addItemAt(obj,j);
Then I add the components:
          var c:ComboBox = new ComboBox ();
            c.labelField='label';
            c.name=numberOfElement.toString();
            c.dataProvider=    newDropDown;
            _h1.addChild(c);
            numComboDropDwns.push(c);
I need a way of looping, getting data and populating each component independently??
Any ideas?
Thanks,
John

I went a different route and solved the issue. For someone looking at a similar problem - this what I ended up doing:
I just loaded one array collection with data for all of the drop-downs on the form. I then populated each dataprovider with individual elements from the array.
for (var i:int = 0; i < numFormElements; i++)
for (var j:int = 0; j < numvalues; j++)
                                var valuefield:String = 'value_' + [j+1];
                                var obj:Object=new Object();
                                obj.label=instFields[i][valuefield].@label;
                                obj.data=instFields[i][valuefield].@data;
                                newDropDown.addItemAt(obj,elementCounter);
                                elementCounter = elementCounter + 1;
I keep track of the element #, number of values for each element and the overall index for the array.
Each data provider is then loaded with the subset from the array:
for (var z:int = (_counter - _numvalues) ; z < _counter; z++)
                            var _label:String=    newDropDown.getItemAt(z).label.toString();
                            var _data:String = newDropDown.getItemAt(z).data.toString();
                            c.dataProvider.addItem({label:[_label],data:[_data]});
This seems to work nicely - each component is created and loaded with only their data. I spent 3 days searching for a way to create a dynamic arraycollection at runtime. I don't think it's possible - but I'm not sure it was the best method anyway.

How to convert an array collection instance to a complex object for interaction with webservice

Hi there,
I have a stubborn problem that I am trying to work out the best way to solve the problem. I am interacting with a WebService via HTTPService calling a method called find(String name) and this returns me a List of ComplexObjects that contain general string and int params and also lists of other Complex Objects. Now using the code:
ArrayCollection newOriginalResultsArray = new ArrayCollection(event.result as Array)
flex converts my complex objects results to an arraycollection so that I can use it in datagrids etc. Now up until this part is all good. My problem is when getting a single instance from the results list, updating it by moving data around in a new datagrid for example - I want to interact with the webservice again to do an create/update. This is where I am having problems - because these webservice methods require the complex object as a parameter - I am struggling to understand how I can convert the array collection instance back to my complex object without iterating over it and casting it back (maybe this is the only way - but I am hoping not).
I am hoping that there is a simple solution that I am missing and that there is some smart cookie out there that could provide me with an answer - or at least somewhere to start looking. I guess if I have no other alternative - maybe I need to get the people who built the service to change it to accept an array - and let them do the conversion.
Any help would be greatly appreciated.

Hi Bert,
According to my knowledge you can use describeType(Object) method which will return an XML... That XML will contain Properties and values just iterate through the XML and create a new Object..   Probably u can use this method...
public function getObject(reqObj:Object,obj:Object,instanceName:String,name:String=null,index:int=-1):Obj ect
            if(!reqObj)
                reqObj = new Object();
            var classInfo:XML = describeType(obj);
            var className:String = instanceName;
            if(name!=null)
                className=name+"."+className;
            if(index!=-1)
                className=className+"["+index+"]";
            for each (var v:XML in classInfo..accessor)
                var attributeName:String=v.@name;
                var value:* = obj[attributeName]
                var type:String = v.@type;
                if(!value)
                    reqObj[className+"."+attributeName] = value;
                else if(type == "mx.collections::ArrayCollection")
                    for(var i:int=0;i<value.length;i++)
                        var temp:Object=value.getItemAt(i);
                        getReqObject(reqObj,temp,attributeName,className,i);
                else if(type == "String" || type == "Number" || type == "int" || type == "Boolean")
                    reqObj[ className+"."+attributeName] = value;
                else if (type == "Object")
                    for (var p:String in value)
                        reqObj[ className+"."+attributeName+"."+p] = value[p];
                else
                    getReqObject(reqObj,value,attributeName,className);
            return reqObj;

Objects in Array / ArrayCollection with FlowLayout

I am pretty baffled by what is happening here:
I am attempting to create an array of visual elements/containers (s:Group, to be precise), and each Group will contain a set of Labels as elements.
I've tried using both Array and ArrayCollection but am having a problem.
It seems to work okay if I simply use groupsArray:Array and do something like:
for (var i:int=0; i<totalGroups;i++) {
     (for var labelNum=0;labelNum<maxLabels;labelNum++) labelGroup.addElement(someLabel);
     groupsArray[i] = labelGroup;
When I add groupsArray[1] as a Panel element, the labels show up... the problem is, they are all stacked right on top of each other.
So what I need to do is be able to set Group.x, Group.y, Group.width, Group.layout, etc.
But when I try to do this, nothing shows up in the group. What's more baffling is that something WILL show up okay for the final group in the queue, but not any of the others... only the last index in the array; I'm trying to set the properties using:
groupsArray[i].width = 300;
I thought maybe I could fix it by using an ArrayCollection, creating each group (with properties), and then using groupsArray.addElement(myGroup) and groupsArray.getItemAt(index)... but none of this seems to work...
The thing that confuses me the most is: (1) i'm getting no compile or runtime errors; and (2) the correct group and its label children show up fine (with x, y, width, and layout correct) for the very last item in the array, but none of the others...

here's a basic example:
var groupArray:ArrayCollection = new ArrayCollection();
var groupLayout:HorizontalLayout = new HorizontalLayout();
for (var i:int=0;i < 10;i++) {
var pageGroup:Group = new Group();
pageGroup.x = 60;
pageGroup.y = 60;
pageGroup.width = 300;
pageGroup.layout = groupLayout;
// parse through XML file for the page and for each word, insert it as a clickable text object
for (var x:int=0;x < 20; x++) {
     var wordLabel:Label = new Label();
     wordLabel.text = "word"+x.toString();
     pageGroup.addElement(wordLabel);
groupArray.addItem(pageGroup);
// tests:
groupPanel.addElement(groupArray[1]); // shows nothing inside Panel
groupPanel.addElement(groupArray[9]); // displays the Group (ie. all children labels) correctly inside Panel, with HorizontalLayout working
// I have also tried: groupPanel.addElement(groupArray.getItemAt(1));
// which gives compile error 1118: Implicit coercion of a value with static type Object to a possibly unrelated type mx.core:IVisualElement.
<s:Panel id="groupPanel" />

Is there a way you can add elements dynamically to an existing array??

hey guys... i need to add elements to an array dynamically... how do i do that?
for example... in one of my functions i do..
     for each(var item:Object in fileList){
          fileListArr.push(item);
and in a later function i need to add one more element to my fileListArr...
so i tried doing
fileListArr[indexNum].push({
     key:videoKey
so i need to have an array which resembles something like this...
Before adding elements...
fileListArr:
     [0]: name:test1
            Size:12K
            caption:testing caption
            number:1
     [1]: name:test2
            Size:12K
            caption:testing caption
            number:2
after adding key to array
fileListArr:
     [0]: name:test1
            Size:12K
            caption:testing caption
            number:1
            key:xyxyyy11y1yy1y1y2y2u33n
     [1]: name:test2
            Size:12K
            caption:testing caption
            number:2
            key:iiduudjmenri112jj2n4n3m2j1j21
any ideas?

Byte array to base64encoder problem, cannot encode a 7.7 MB file

hey guys, so ive been trying to use the base64encoder to encode a bytearray which is then sent thru a webservice to the server to be decoded.
and as the subject of this post suggests, i have been having problems encoding a big file,
forexample i tried to upload/convert a 84KB image and it worked just fine... the trace of the string ended with a "==" which i believe means that the conversion is complete...
but when i try to upload a 7.7MB image, it is, i guess, crashing... i dont see any "==" in the string... so i guess its not working... i was wondering if there is any any type of file size limit or soemthign for the encoding...

any help will be greatly appretiated!! thanks in advace!

yeah i did actually... except i think i changed a LOT of code since i last posted this article...
so i dont remember where this code is exactly... lol
i have the following code now...
hope this helps
i use a a lot of webservices... so there is some of that code included in there aswell...
* This file will do the file upload. It has been suggested to me multiple times, that using a queueing system for
* file upload is not a good idea. Instead I declared a counter and used the final function to fire the next item
* in the array. this also makes canceling a routine easier.

Referencing values in Array Collection?

I'm using a Remote Object to pass an argument to a CFC. I
then query a table according to the value of the argument passed in
('where' clause). I return a single record result as a query in
Flex (event.result) and set it as an Array Collection, example:
myAC = new ArrayCollection;
myAC.source = event.result as Array;
I can take this AC and set it as a dataprovider for a data
grid or list without problem. What I'd like to do is pull specific
data from the AC and use it in my Flex app. For example, the
results of my query will return 1 record only, but contains many
columns from my table. It might contain an ID, a username, a first
and last name, maybe a phone number, etc. All this info for that
single record will be stored in the array collection. What I want
to do is be able to reference this data in Flex.
For instance, if I need to display the phone number (stored
as phoneNumber from my query) in the array collection, how can I do
this? myAC.phoneNumber? myAC.getItemAt(0).phoneNumber?
Any guidance is appreciated

I'm not sure about dealing with a Remote Object / CFC
configuration, but if your collection essentially ends up like:
var myAC:ArrayCollection = new ArrayCollection([{name:
'First', phoneNumber: '555'}]);
Then yes you should be able to access it with:
myAC.getItemAt(0).phoneNumber
I take this has not worked?

Array of VO's

I have got a VO called personVO that have got firstname and
lastname.
Then I have an array that contains the personVO.
In my interface it is then possible to select a personVO.
The selected personVO would I like to have in the variable
selectedPerson.
How do I do that?
First I thought about copying the selected personVO into
selectedPerson. But I do not want to have another copy of the
values because they are already in the array.
Then I thought about making the selectedPerson to some kind
of pointer, pointing into the array.
But I do not want the selectedPerson to have an index value
to the selected personVO. I want the selectedPerson to point
directly to the VO.
I would be able to call the selected persons firstname like
this selectedPerson.firstname.
Is this possible?

yes, use arrayCollection if you plan to programatically
update the VO, as you clearly plan.
In almost all cases, assigning a complex object to a variable
creates a reference/pointer to the original object. So if you do:
var voSelectedPerson:personVO = acPersons.getitemAt(0);
you have a reference into the item in the collection not a
copy.
So,
voSelectedPreson.firstname = "joe";
puts that value into the correct item in the collection.

AdvancedDataGrid - create Array (cfquery) with children for hierarchical data set

I'm trying to create an AdvancedDataGrid with a hierarchical
data set as shown below. The problem that I am having is how to
call the data from a ColdFusion remote call and not an
ArrayCollection inside of the Flex app (as below). I'm guessing
that the problem is with the CFC that I've created which builds an
array with children. I assume that the structure of the children is
the issue. Any thoughts?

I had similar problems attempting to create an Array of
Arrays in a CFC, so I created two differents scripts - one in CF
and one in Flex - to build Hierarchical Data from a query result.
The script in CF builds an Hierarchical XML document which is then
easily accepted as HIerarchical Data in Flex. The script in Flex
loops over the query Object that is returned as an Array
Collection. It took me so long to create the XML script, and I now
regret it, since it is not easy to maintain and keep dynamic.
However, it only took me a short while to build this ActionScript
logic, which I quite like now (though it is not [
yet ] dynamic, and currently only handles two levels of
Hierarchy):
(this is the main part of my WebService result handler)....
// Create a new Array Collection to store the Hierarchical
Data from the WebService Result
var categories:ArrayCollection = new ArrayCollection();
// Create an Object variable to store the parent-level
objects
var category:Object;
// Create an Object variable to store the child-level
objects
var subCategory:Object;
// Loop through each Object in the WebService Result
for each (var object:Object in results)
// Create a new Array Collection as a copy of the Array
Collection of Hierarchical Data
var thisCategory:ArrayCollection = new
ArrayCollection(categories.toArray());
// Create a new instance of the Filter Function Class
var filterFunction:FilterFunction = new FilterFunction();
// Create Filter on the Array Collection to return only
those records with the specified Category Name
thisCategory.filterFunction =
filterFunction.NameValueFilter("NAMETXT", object["CATNAMETXT"]);
// Refresh the Array Collection to apply the Filter
thisCategory.refresh();
// If the Array Collection has records, the Category Name
exists, so use the one Object in the Collection to add Children to
if (thisCategory.length)
category = thisCategory.getItemAt(0);
// If the Array Collection has no records, the Category Name
does not exist, so create a new Object
else
// Create a new parent-level Object
category = new Object();
// Create and set the Name property of the parent-level
Object
category["NAMETXT"] = object["CATNAMETXT"];
// Create a Children property as a new Array
category["children"] = new Array();
// Add the parent-level Object to the Array Collection
categories.addItem(category);
// Create a new child-level Object as a copy of the Object
in the WebService Result
subCategory = object;
// Create and set the Name property of the child-level
Object
subCategory["NAMETXT"] = object["SUBCATNAMETXT"];
// Add the child-level Object to the Array of Children on
the parent-level Object
category["children"].push(subCategory);
// Convert the Array Collection to a Hierarchical Data
Object and use it as the Data Provider for the Advanced Data Grid
advancedDataGrid.dataProvider = new
HierarchicalData(categories);

Retrieving Key from array

Hi
I need a dynamic way of retrieving all the "keys" from a array.
Found this which is exactly what I need but doesn't work as expected in my case:
var myObject:Object = {key1:"value1",key2:"value2"}
for (var s:String in myObject)
trace("key:",s,"value:",myObject[s]);
//key: key2 value: value2
//key: key1 value: value1
My case:
var testArray:Array = new Array()
testArray = DG1.dataProvider.toArray() // create array from dataprovider
I've tested this array and it performs "correctly" as an array but when I try the above mentioned method it traces as follows:
key: 0 value: [object Object] (key not being what I need)
What I need:
dgArr.push({partNo:event.target.data['partNo'+i],description:event.target.data['descriptio n'+i],cost:event.target.data['cost'+i]});
trace (????) //outputs = partNo, description, cost etc...
Thanks for any help.

your dataprovider values are also objects. use:
function listF(dp:DataProvider):void{
for(var i:int=0;i<dp.length;i++){
for(var s:String in dp.getItemAt(i)){
trace(s,dp.getItemAt(i)[s]);

Array...TileList...Help :(

Here is the situation codeWorld....i'm losing it .....in my brain the variables or items in a TileList component are arranged just like a high powered Array. The problem is I cant or dont remember a way to search it with code. I thought I could just put or use code like this to access the variables:
trace(myTileList.index[1].label);
To get the variable of in the second tile or any tile for that matter without it being selected. I already built this InstantMessenger using a TileList component and I dont want to go through all that code and re-build my own custom clip etc...blah blah...i digress but thats beside the point.
The point is how do i access a variable in the TileList through code like the code above...I tried using a DataProvider but it wont let me access the variables that way either.......help.....help....i'm dying..............................to know....
somebody save me ......i officially feel like a rookie now.

...iT wErKs.......woooooooooooot!!!......thanks a million.....i owe you one.... .....i'll tapdance at yo wedding....just dont get married soon
for the record....i used a for loop to loop thru the list.....i needed it to see if a variable is equal to another....and if so execute another function....
as simple as it is.....i couldnt figure it out to save my life.......but thank to RayRay...or SugarRay...or what ever he nicknames himself ....lol...i'm on track now
sample code how i used it:
var example = "randomname";
for(var i=0; i<myTileList.length; i++)
    if(myTileList.getItemAt(i).label==example)
          executeFunction();
     else {
          //do nothing
}//end for loop

Loops in arrays or structures

Loops in arrays or structures
I was given a project on html reports and
They have advised me to use Loops in arrays or structures
At this point I am a novice at this html reporting system. I
would like to know how I can use loops in arrays or structures.
How is it beneficial are
1. Structures
2. Arrays
3. loops in for both
for my reports.
Countless thanks in advance

Structures are great if you understand them, they are
basically just arrays organized by keywords rather than index
numbers.
Arrays are very nice, as you can just run through loops to
access each element, as they are all indexed by numbers 0-x.
loops are great to navigate through both. All you have to do
is set an loop to run through x amount of iterations of the array
or structure (where x is the length of the array, or number of
elements in the structure). Loops are great due to the small amount
of code they require.

How Do I Load An Animated GIF Into PictureBox Control From Byte Array?

I'm having a problem with loading an animated GIF int a picturebox control in a C# program after it has been converted to a base64 string, then converted to a byte array, then written to binary, then converted to a base64 string again, then converted to
a byte array, then loaded into a memory stream and finally into a picturebox control.
Here's the step-by-step code I've written:
1. First I open an animated GIF from a file and load it directly into a picturebox control. It animates just fine.
2. Next I convert the image in the picturebox control (pbTitlePageImage) to a base64 string as shown in the code below:
                if (pbTitlePageImage.Image != null)
                    string Image2BConverted;
                    using (Bitmap bm = new Bitmap(pbTitlePageImage.Image))
                        using (MemoryStream ms = new MemoryStream())
                            bm.Save(ms, ImageFormat.Jpeg);
                            Image2BConverted = Convert.ToBase64String(ms.ToArray());
                            GameInfo.TitlePageImage = Image2BConverted;
                            ms.Close();
                            GameInfo.TitlePageImagePresent = true;
                            ProjectNeedsSaving = true;
3. Then I write the base64 string to a binary file using FileStream and BinaryWriter.
4. Next I get the image from the binary file using FileStream and BinaryReader and assign it to a string variable. It is now a base64 string again.
5. Next I load the base64 string into a byte array, then I load it into StreamReader and finally into the picturebox control (pbGameImages) as shown in the code below:
byte[] TitlePageImageBuffer = Convert.FromBase64String(GameInfo.TitlePageImage);
                        MemoryStream memTitlePageImageStream = new MemoryStream(TitlePageImageBuffer, 0, TitlePageImageBuffer.Length);
                        memTitlePageImageStream.Write(TitlePageImageBuffer, 0, TitlePageImageBuffer.Length);
                        memTitlePageImageStream.Position = 0;
                        pbGameImages.Image = Image.FromStream(memTitlePageImageStream, true);
                        memTitlePageImageStream.Close();
                        memTitlePageImageStream = null;
                        TitlePageImageBuffer = null;
This step-by-step will work with all image file types except animated GIFs (standard GIFs work fine). It looks like it's just taking one frame from the animation and loading it into the picturebox. I need to be able to load the entire animation. Does any of
the code above cause the animation to be lost? Any ideas?

There is an ImageAnimator so you may not need to use byte array instead.
