re-writing to an existing text file from AIR

[eliddell]

i am trying to write text to an existing text file in the same folder as my air app..

import flash.filesystem.File;
import flash.filesystem.FileStream;
import flash.filesystem.FileMode;

var docDir:File = File.documentsDirectory;
var dskTopFileStream:FileStream = new FileStream();
var fileString:String = docDir.nativePath;
var dskTopFile:File = File.documentsDirectory;
    
dskTopFile = dskTopFile.resolvePath(fileString+"test.txt");
dskTopFileStream.openAsync (dskTopFile, FileMode.UPDATE);
dskTopFileStream.writeUTFBytes ("Hello World!");
dskTopFileStream.close ();

the code doesnt do anything to the file

dskTopFile = dskTopFile.resolvePath(fileString+"test.txt");
trace(fileString);
trace(fileString + "test.txt");
dskTopFileStream.openAsync (dskTopFile, FileMode.UPDATE);

Run those traces and let me know what you come up with. I think you might need to do this:

dskTopFile = dskTopFile.resolvePath(fileString+"\test.txt");

But I'm not sure.

traces don't seem to work at all

Yeah... I'm working on it. Gimme a minute.

Well,.. actually, "trace" will work, but you have to go into debug mode to see your traces when working with AIR files. Basically, instead of hitting CTRL+Enter to test your movie, just use CRTL+SHIFT+Enter. You'll see your traces then.

weird.. i couldn't get the trace to work so i created a dynamic text field that was my fileString variable... found the file!!!! but thats not where i wanted it.. it is going to the My Documents folder.. while my actual air file is in in the programs/writeTest folder.. i wanted the file to be in the same folder as the AIR file.. ho do i do that?

I got this to work:

import flash.filesystem.File;
import flash.filesystem.FileStream;
import flash.filesystem.FileMode;

var docDir:File = File.documentsDirectory;
var dskTopFileStream:FileStream = new FileStream();
var fileString:String = (docDir.nativePath + "\\test.txt");
var dskTopFile:File = File.documentsDirectory;
dskTopFile = dskTopFile.resolvePath(fileString);

dskTopFileStream.openAsync (dskTopFile, FileMode.WRITE);
dskTopFileStream.writeUTFBytes ("Hello World!");
dskTopFileStream.close ();

trace(fileString);

Change

var docDir:File = File.documentsDirectory;

to:

var docDir:File = File.applicationResourceDirectory;

You may find this link quite useful for making AIR apps. I personally reference it on a daily basis.

that gives me an error...

1119: Access of possibly undefined property applicationResourceDirectory through a reference with static type Class.
