Actionscript 3 and AIR - FileStream

[deftones_sv]

Hi.

look at this actionscript code:

import flash.filesystem.*;
import flash.events.Event;
import flash.net.FileFilter;

var fileToOpen:File = new File();
var txtFilter:FileFilter = new FileFilter("Text", "*.as;*.css;*.html;*.txt;*.xml");

try 
{
    fileToOpen.browseForOpen("Open", [txtFilter]);
    fileToOpen.addEventListener(Event.SELECT, fileSelected);
}
catch (error:Error)
{
    trace("Failed:", error.message);
}

function fileSelected(event:Event):void 
{
    var stream:FileStream = new FileStream();
    stream.open(event.target, FileMode.READ);
    var fileData:String = stream.readUTFBytes(stream.bytesAvailable);
    trace(fileData);
}

The function fileSelected causes the error: 1118: Implicit coercion of a value with static type Object to a possibly unrelated type flash.filesystem:File. ... exactly this line:

stream.open(event.target, FileMode.READ);

I got it from: http://help.adobe.com/es_ES/AS3LCR/Flash_10.0/flash/filesystem/File.html#browseForOpen()

Thanks for the help.

Hola estas usando Flash Cs3 o Cs4 para la autoria de esta aplicacion AIR? Una pequeña recomendacion la proxima vez que quieras publicar codigo insertalo como codigo de JAVA para que se pueda leer mas facilmente, leer el codigo que enviaste antes es imposible en esa forma.

hola, estoy usando flash cs3... y gracias por la sugerencia, me confundí en las opciones del editor de este foro

[Michael Borbor]

En todo caso al codigo de la ayuda le falta algo agregalo asi y funcionara

                        import flash.filesystem.*;
               import flash.events.Event;
               import flash.net.FileFilter;

               private var fileToOpen:File = new File();
               private var txtFilter:FileFilter = new FileFilter("Text", "*.as;*.css;*.html;*.txt;*.xml");

               private function fileOpen():void{
                    try 
                    {
                         fileToOpen.browseForOpen("Open", [txtFilter]);
                         fileToOpen.addEventListener(Event.SELECT, fileSelected);
                    }
                    catch (error:Error)
                    {
                         trace("Failed:", error.message);
                    }
               }

               private function fileSelected(event:Event):void 
               {
                    var stream:FileStream = new FileStream();
                    stream.open(File(event.target), FileMode.READ);

                    var fileData:String = stream.readUTFBytes(stream.bytesAvailable);
                    trace(fileData);
               }

No te preocupes el foro es relativamente nuevo para la mayoria.

Gracias por tu ayuda, ahora funciona... solo una ultima pregunta ¿sabes cual es el metodo para capturar la ruta del archivo seleccionado en el cuadro de dialogo?

[Michael Borbor]

Me parece que documentLocalPath tiene esa info dentro de la referencia que haces a File.

You have to cast the target to File as evt.target and evt.currentTarget are typed as Object.

And use currentTarget instead of target (see docs)

stream.open(event.currentTarget as File, FileMode.READ);

and erhm, keep it English in here please.

Hi,

   Wondering if someone helped you. I want to open xsl or csv file and using below code

var file:File = evt.currentTarget as File;
        file = file.resolvePath(file.nativePath);
        var fileStream:FileStream = new FileStream();
        fileStream.open(file, FileMode.READ);      
        var fileData:String =  fileStream.readUTFBytes(fileStream.bytesAvailable);        
        var endings:Array = [File.lineEnding, "\n", "\r"];

but for some reason it return "ÐÏ ࡱ á" funny value. Any idea why don't i get the correct data from file.

belwo is the csv file i am trying to open.
