In C you can pass a reference to a data item as a parameter to a function. then within the function you can write to that address thus passing back a value to the caller. Can you do anything similar in AS3?
I know you can use the return statement but I want to return a status by that mechanism plus a value in a parameter.
I need to load data from a database, so I created the following function and placed it in frame 2 on the main timeline.
Code:
getQuestionSet = function (category:String, subject:String, level:Number, count:Number):Array {
var questionSet:Array = new Array();
var writeV:LoadVars = new LoadVars();
[Code]...
Whenever I try to call the function, it fails to set the value of the questions array. It always appears empty(questions[0]-questions[10] have the value undefined). But, if I check the values from within the function after I have set them, it works, so I know that it is receiving the values. What am I doing wrong?
Code:
questions = getQuestionSet("Art and Music", "Art", 1, 10);
Here is an example of how I have would call the function.
How can I set default values for the parameters of a function in AS2? I am trying the common way but it doesn't work...
Code:
private function myFunction (param1:Number = 3,
param2:String = "a string",
param3:Boolean = false, etc ....):Void
{
....
}
How can i make a function that changes the value of variables that are passed into it. For example:

I want the example above to add 5 to the variable pie1 (or whatever variable is passed in) and change pie2 to the cosine of pie3. Hope this makes sense :P
Say I have four sub-classes of 'Car'. One for each color. I want to have one function that can build and return a 'color-car' sub-class based on the passed value. This is a dumb example, I know, but it is precisely what I am trying to do only on a smaller scale.
public class Car
{
}
public class BlueCar extends Car
[code]....
Ok. You get it. This doesn't work for a reason unknown to me. I get 1118 errors which complain about conversion of BlueCar into Car, etc...
I am using Flex's Alchemy library to generate SWC's out of C files. I have a byte array (unsigned char buffer[size]) in the c-layer that I'd like to return to the ActionScript layer as a ByteArray. Do I have to iterate through the array and explicitly call AS3_Set on each element or is there a way to just return the entire C array at once?
View 2 RepliesI am sending variables from my html page:
Code:
<param name="FlashVars" value="nameCheck=boo&imageCheck=image01.jpg">
...in the parameters section of the flash object code.
I know that to extract the info I need to basically use:
Code:
var paramObj:Object = LoaderInfo(this.root.loaderInfo).parameters;
...in my as3 code but I am wondering what would be the syntax to return a text field containing the sent variable 'boo' and fill an image area with the file name from the variable 'imageCheck'?
I'm trying to take an xml object, parse through it, turn the appropriate elements in object properties. Then, finally, pushing each object an array.
Then I need this array accessible outside of the XML.onLoad() function (since it returns nothing, I lose my array).

View 2 RepliesI have a project made in flex, using php data services to access a sql server database, and I need to convert it to mysql, I have changed all my php services from sqlsrv to mysqli. Something like this:
$this->connection = mysqli_connect(SERVER,USERNAME,PASSWORD,DATABASE); // Start Connection
$ssqlstring = "select * from Users";
$runssql = mysqli_query($this->connection, $ssqlstring);
while($user = mysqli_fetch_array($runssql)) {
$users[$user["ID"]] = $user;
} return $users;
It worked fine on sqlsrv but with mysqli it returns to flex the INT, BIT or DATE values as string the main Datatypes on mysql are INT,VARCHAR,BIT(1),DATETIME,DATE (same as sqlsrv)
and on the flex the return types are mainly as object[]

I'm making an activity that involves measuring the depth of a fictitious river at various points. I have an array containing those depths at the various points and a slider for traversing through the depths and outputting to a textfield.
As the user moves the slider up and down, they can see the depth of the river at that point and plot it onto a graph. What I would like to do is be able to figure out the depths inbetween the explicitly defined values.
here is the code, it's pretty simple:

How would I go about figuring out the values inbetween?
I am developing in Flash Builder 4.5 using as3.
I have created a class to connect, write and read to a TCP Socket using 'import flash.net.Socket;'
Within this class is an event listener which reads the incomming data:
Code:
socket.addEventListener(ProgressEvent.SOCKET_DATA, readSocketData);
private function readSocketData(progressEvent:ProgressEvent):void {var response:String = socket.readUTFBytes(socket.bytesAvailable);
trace response;}
My problem is how to output this data back to my main application. Ultimately I want to process the data and output it in a text box.
I am trying to connect to an FMS application without flash (no SWF). To the best of my knowledge,the only way to accomplish this is thru the admin APIs, is that correct? If so, how do I return meaningful values from the admin API? I can call functions and stuff using the broadcastMsg API call but I can't seem to get back any values. All that is returned is a useless "Success" type message. I have tried using shared objects and the getSharedObjects API call, but the call doesn't return any info on the contents of the shared objects, just their names and some info on their persistance.
Is there another way of accomplishing my goal outside of the Admin API? If not how do I return meaningful variables from the Admin API? Is there a way to hack or extend the admin API?
is it possible to declare function this way
ActionScript Code:
function startShake(e:MouseEvent, num1, num2):void
what i mean is it possible to send to the function not only en event but also a variable and a second question how can i access
ActionScript Code:

this array that function return.
I created code based on a site I found that puts the XML into CSV's, here is the code:
var myXML:XML = new XML(); // instance of XML Obj.
myXML.ignoreWhite = true;
myXML.load(config.xml)
[Code].....
So after all of that, my question is, if that one tag XML file that I gave an example for has 100 or so lines, is there a way to call it without having to know the line it is on so you don't need to put the array value in all of the time?
I have a function that checks for something when the user clicks a button. if that something is found, an alert comes up saying that it has been found and asks them if they would like to allow this to happen, or undo the action that caused the something to be found. the code looks like this:
Alert.show(thisString1, "Conflict: Multiple Projects", 3, this, conflictAnswer);
upon pressing "Yes" or "No", the conflictAnswer function will be called... it looks like this:
private function conflictAnswer(event:CloseEvent):void[code]....
but it didn't work.
EDIt: After reading the first respond, i've come up with this:
answers[0] = cPositions[i][0];
answers[1] = cPositions[i][1];[code]..........
I'm using String.split to parse a command line string into an array of strings. The result is then used to call a function using the Function.apply API.If apply(null, ["17"]) is called with this function:[code]does not work (expected output: false Boolean; actual output: true Boolean).Is there a way to make it recognize "true" and "false" (or anything else) as Boolean values, just like it does with numerical strings? Ideally "true" and "false" should also remain valid string values.
View 1 RepliesI'm using String.split to parse a command line string into an array of strings. The result is then used to call a function using the Function.apply API.
If apply(null, ["17"]) is called with this function:
static function test(foo:int):void
{
trace(foo, typeof(foo));
}
it works as expected (output: 17 number).
However, calling apply(null, ["false"]) or apply(null, ["0"]) with this function:
static function test(foo:Boolean):void
{
trace(foo, typeof(foo));
}
does not work (expected output: false Boolean; actual output: true Boolean). Is there a way to make it recognize "true" and "false" (or anything else) as Boolean values, just like it does with numerical strings? "true" and "false" should also remain valid string values.
I am creating a game in Flash 8 with AS 2 and i have few questions to ask.First of all, i am stuck for 2 days at creating a Laser Beam from tower to the target.I searched all internet for solutions but i can't really find one, so i'll try posting questions myself..First i tryed to create and effectHolder into which every laser beam was created, because it seems i can create only one line in each movieClip.[code]This was triggered eveytime it had a target.With every tower that fired a laser i created it was getting more lag, so i tryed selfdestructing after few time.[code]The problem is that i didn't know how to pass the coordonates of the tower and the target to the MovieClip so it knows where to create the line.[code]how to create that line ("laser beam") for each tower, without lagging so much.

I am refactoring some code. I have a PHP page that contains a MySQL query and stores the result in a PHP variable $my_result. This result is then echoed to a Flash SWF during embedding with SWFObject. I now want to call this PHP page that makes the query from a javascript function like so - one change I have made to the PHP is that instead of storing the result in a variable $my_result I am echoing the result.

I'm having my first go at creating a custom component that lays out items in a grid. I have made a selection of inspectable properties accessed though getter/setter methods. Some of these parameters are dynamic, and change when the user resizes the component or changes another linked value. Is it possible to make the parameters panel update with the new values when a change takes place. Without this, the user will not have accurate feedback on the values stored in the component. Does anyone know if this is possible (or difinitely impossible)?
View 1 RepliesI'm having some trouble passing parameters with a function that is itself being passed as a parameter.In my application code I'm instancing that class five times:they are buttons in a menu.In that class, I've got an onRelease handler that does a number of things when a button is released, one of which is to invoke a function that is defined in the application level of the code.My problem is that I don't know how to send the function parameters.In my StandardButton class I have:

I tried to simply set up a variable so when the function returns, it has a storage variable.
Then i tried for a function to retrieve the variable content
However when i call the trace(mc) it fails as undefined [code]...
