flash data integration: I can't find a way to fix this.
1. The scenario: A web service is reading the nodes of an XML file and
represting them into arrays.
2. A Flash UI is binding to these webservice methods (which return arrays) to
Actionscript arrays.
------
Here is the code:
1. The XML structure:
<songs>
<song><label>Song1</label><data>mp3/song1.mp3</data></song>
<song><label>Song2</label><data>mp3/song2.mp3</data></song>
</songs>

2. The webservice method:

[WebMethod(Description = "Get the song title", CacheDuration = 1)]
public String[] GetMp3SongLabel() {
ArrayList Mp3SongLabel_arraylist = new ArrayList();
XmlTextReader reader = new
XmlTextReader(http://localhost/mp3/mp3.xml");
reader.WhitespaceHandling = WhitespaceHandling.None;
while (reader.Read()) {
if (reader.Name == "label") {
Mp3SongLabel_arraylist.Add(reader.ReadString());
}
}
reader.Close();
String[] Mp3SongLabel_array = (String[])
Mp3SongLabel_arraylist.ToArray(typeof(String));
return Mp3SongLabel_array;
}

3. The AS code:

import mx.services.WebService;

//creating the webservice
var Mp3Player_service:WebService = new
WebService("http://localhost/Mp3WebService.asmx?wsdl");
Mp3Player_service.onFault = function(fault) {
//show "Can't find the XML file"
Main.Mp3Player.Status_txt.text = "Can't find the XML file";
classes.GlobalClass.Mp3PlayerStatusText_str = Main.Mp3Player.Status_txt.text;
//trace the actual WebService error, generated automatically from Flash Player
trace(fault.faultstring);
}
var SongLabel_array:Array = new Array(Mp3Player_service.GetMp3SongLabel());
trace(SongLabel_array.length);


The Problem:
-> the trace function returns 1 as a length. The webservice method itself
bound to a aspx page returns the actual array. Similar binding to an
actionscript array doesn't do anything.

Any Solution?

------
Note: Please no examples and links for Flash Remoting, FlashOrb, etc. And no
examples with WebServiceConnector and visual binding.

I would appreciate pure code, in pure developer's way. If anyone could help,
will be great

This code was generated in about 10 seconds from the free code generator
available at www.DoneInAFlash.com :

AS:
Result_obj = ws.Get_Customers();
ws.onLoad = trace("Loading...");
Result_obj.onResult = function(result) {
DG_ary=[];
for (i=0;i<result.length;i++){DG_ary.push(result);}
}


.NET Web Service:

Public Class Customers
Public ContactName As String
Public CompanyName As String
Public CustomerID As String
End Class


<WebMethodAttribute(Description:=" Get Customers")> Public Function
Get_Customers() As Customers()
Dim myCommand As New OleDbCommand("select * from [Customers]", myConnection)
myConnection.Open()
Dim myDataAdapter As New OleDbDataAdapter
myDataAdapter.SelectCommand = myCommand
Dim myDataSet As New DataSet
myDataAdapter.Fill(myDataSet)
myConnection.Close()
Dim x As Integer
Dim CustomersArray As Customers() = New
Customers(myDataSet.Tables(0).Rows.Count-1) {}
For x = 0 To myDataSet.Tables(0).Rows.Count - 1
CustomersArray(x) = New Customers
CustomersArray(x).ContactName =
nz(myDataSet.Tables(0).Rows(x).Item("ContactName"))
CustomersArray(x).CompanyName =
nz(myDataSet.Tables(0).Rows(x).Item("CompanyName"))
CustomersArray(x).CustomerID =
nz(myDataSet.Tables(0).Rows(x).Item("CustomerID"))
Next
Return CustomersArray

thanks,

I'll check it out.

Anyway I found a way, fixing slightly the web service code as:

[WebMethod(Description = "Get the song title", CacheDuration = 1)]
public String[] GetMp3SongLabel() {
ArrayList Mp3SongLabel_arraylist = new ArrayList();
int i = 0;
String[] my_array = new String[10];
XmlTextReader reader = new XmlTextReader(Mp3Dir + "mp3.xml");
reader.WhitespaceHandling = WhitespaceHandling.None;
while (reader.Read()) {
if (reader.Name == "label") {
//Mp3SongLabel_arraylist.Add(reader.ReadString());
my_array = reader.ReadString();
i++;
}
}
reader.Close();
//String[] Mp3SongLabel_array = (String[])
Mp3SongLabel_arraylist.ToArray(typeof(String));
//return Mp3SongLabel_array;
return my_array;
}
-------------------

And then I found another solution, beautiful to be injected directly in a
Flash DataSet, and then used the dataset objects freely everywhere around the
UI. The XML should be changed so to include attributes, as: <song label=""
data="" />.

And then you can create directly array of objects, bind them in Flash in a
DataSet and play around with them in arrays, objects, or whatever you like
format.

Could be of help to someone, as .NET webservice examples are really limited
(for now):

public class Song {
public String label;
public String data;
}

public class myWebService : System.Web.Services.WebService {

public myWebService() {
}

[WebMethod(Description = "Get the songs as objects with properties",
CacheDuration = 1)]
public Song[] GetMp3Songs() {
Song[] Songs_array = new Song[10];
int i = 0;
XmlTextReader reader = new XmlTextReader(Mp3Dir + "mp31.xml");
reader.WhitespaceHandling = WhitespaceHandling.None;
while (reader.Read()) {
if (reader.Name == "Song") {
Songs_array = new Song();
Songs_array.label = reader.GetAttribute(0).ToString();
Songs_array.data = reader.GetAttribute(1).ToString();
i++;
}
}
reader.Close();

return Songs_array;
}

}
