Question

A section of a Flash animation I’m creating involves an area where people can write on a notepad, save their work and update it at a later time. The file will be downloaded by users before they run it, rather than from a webpage. Here is the code I have so far:

import flash.events.MouseEvent;
import flash.net.FileReference;
import flash.display.MovieClip;
import flash.events.Event;

stop();

var MyNotes:FileReference = new FileReference()


Save_btn.addEventListener (MouseEvent.CLICK, SaveText);

function SaveText(Event:MouseEvent):void {
MyNotes.save(TypeOwn_txt.text, "MyNotes.txt");
}

Load_btn.addEventListener (MouseEvent.CLICK, LoadText);

function LoadText(Event:MouseEvent):void {
MyNotes.addEventListener(Event.SELECT, onFileSelected);
var swfTypeFilter:FileFilter = new FileFilter("Text Files","*.txt; .html;*.htm;*.php");
var allTypeFilter:FileFilter = new FileFilter("All Files (*.*)","*.*");
MyNotes.browse([swfTypeFilter, allTypeFilter]);
}

function onFileSelected(event:Event):void
{
trace("onFileSelected");
MyNotes.addEventListener(Event.COMPLETE, onFileLoaded);
MyNotes.load();
}

function onFileLoaded(event:Event):void
{
var fileReference:FileReference=event.target as FileReference;
var data:ByteArray=fileReference["data"];
TypeOwn_txt.text=data.toString();
}

The problem is I receive a “Symbol ‘Structure Summary’, Layer ‘Actions’, Frame 29, Line 19 1119: Access of possibly undefined property SELECT through a reference with static type flash.events:MouseEvent.
” in regards to the line “MyNotes.addEventListener(Event.SELECT, onFileSelected);”. I’ve done some research and understand this is something to do with the parent not being identified as a MovieClip, or something along those lines. I’m still not sure, however I don’t have a clue how to proceed! Thanks.

Just to let you know the problem is solved, although I really don’t know how. I used this site for a template and worked backwards. I’ll put in the working Code below in case it’s of use to somebody else.

import flash.events.MouseEvent;
import flash.net.FileReference;
import flash.net.FileFilter;
import flash.utils.ByteArray;
import flash.events.MouseEvent;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.display.MovieClip;

var myNotes:FileReference;

Load_btn.addEventListener(MouseEvent.CLICK, onLoadClicked);

function onLoadClicked(event:MouseEvent):void
{
    trace("onBrowse");
    myNotes=new FileReference();
    myNotes.addEventListener(Event.SELECT, onFileSelected);
    var swfTypeFilter:FileFilter = new FileFilter("Text Files","*.txt; *.html;*.htm;*.php");
    var allTypeFilter:FileFilter = new FileFilter("All Files (*.*)","*.*");
    myNotes.browse([swfTypeFilter, allTypeFilter]);
}


function onFileSelected(event:Event):void
{
    trace("onFileSelected");

    myNotes.addEventListener(Event.COMPLETE, onFileLoaded);
    myNotes.addEventListener(IOErrorEvent.IO_ERROR, onFileLoadError);
    myNotes.load(); 
}

function onFileLoaded(event:Event):void
{
    var fileReference:FileReference=event.target as FileReference;
    var data:ByteArray=fileReference["data"];
    textArea.text=data.toString();
    myNotes.removeEventListener(Event.COMPLETE, onFileLoaded);
    myNotes.removeEventListener(IOErrorEvent.IO_ERROR, onFileLoadError);
}

function onFileLoadError(event:Event):void
{
    myNotes.removeEventListener(Event.COMPLETE, onFileLoaded);
    myNotes.removeEventListener(IOErrorEvent.IO_ERROR, onFileLoadError);

    trace("File load error");
}   

Save_btn.addEventListener (MouseEvent.CLICK, SaveText);

function SaveText(Event:MouseEvent):void {
    myNotes=new FileReference();
    myNotes.save(textArea.text, "MyNotes.txt");
}

Thanks to everyone who contributed.
