[Flashcoders] Read and save xml file on disk

[natalia Vikhtinskaya]

Hi to all friends
I have to create stand alone application that can read xml file then after
editing save it on the disk. I need to do that by FlashCs6. I know that
FileReference.load() : Loads data from a file selected by the user.
FileReference.save() : Saves data to a file location selected by the user.
Is it possible to save and read without the user?
What is the better way for this task?
Do you know any good tutorials with examples on this subject? This task it
new for me and I want to read about that more.

Thank you in advance.

Hi,

I presume your building an AIR app, so look into File.applicationStorageDirectory and resolvePath. You can read and write behind the scenes without user intervention.

Natalia,

You can use the File (see e.g. "applicationDirectory" or "resolvePath")
and Filestream (open, read<x>, and write<x>) functions, but these are only
available if you're using Air (other wrappers like Zinc have similar
functionality). If it's an executable created by simply Publishing with
Flash Player as the target, I think security issues prevent you from doing
this.

HTH,

Thank you for your answers. Unfortunately I don't know AIR or Zinc. I
looked for a way to publish this application as swf file and then convert
it to exe. I did that before with games. So no way to do that without AIR
or Zinc?

[David Benman]

AIR is another publishing method available in Flash and because it creates an executable that removes many of the Flash player's security restrictions. Prior to Flash CC you could also create a Mac or Windows projector that would save a file.

I think most methods still require user interaction, but its usually not that hard to scare up some sort of user interaction to trigger the saving. The user doesn't necessarily need to choose the save location each time, just the save process needs to be triggered by a user interaction.

Here how I try to save xml in the same folder where is my app

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

//personnel. xml file
......

// save to disk
var appDirectory:File = File.applicationDirectory;
var newFileStream:FileStream = new FileStream();
var fileString:String = appDirectory.nativePath;
var appFile:File = File.documentsDirectory;
appFile = appFile.resolvePath(fileString+"\personnel.xml");
trace(fileString+"\personnel.xml")
it gives path myfolderpersonnel.xml instead of myfolder\personal.xml

How to solve this problem?

[Jim Hayes]

you need to escape the \ like so "\\"

appFile = appFile.resolvePath(fileString+"\\personnel.xml");
trace(fileString+"\\personnel.xml")

Or use a / which I think works both on PC and the mac (which \ will not, that will only work on windows)
Forgive me if I'm wrong on that one.

Thank you! "\\' works.

[Henrik Andersson]

Just use File.separator, it will get you the correct one if you care.
