FileSystemObject: relative path trouble

Copy linkTweet thisAlerts:
Nov 26.2005

Helo. I am writing a program for personal use with Javascript, that is it does not run from the internet, and in this program I have to work with files. For this I use the ActiveX FileSystemObject. The problem is that when I try to write the path of my file relative, like “data.txt”, or “.data.txt”, I get an error. By extensive investigation I found out that in these cases the browser tries to find the file on the Desktop… When I write absolute paths, however, everything is all right.

Any ideas what I may be doing wrong?

I would appreciate it is you sent an example…

Thanks a lot,

Martas

@gphNov 26.2005 — I'm not sure if this is what you're after. This is what I use to locate an HTA and from there the files it requires.
<i>
</i>var app_path=location.href.toLocalPath().folderOf();

String.prototype.toLocalPath=function(){
return unescape(this.slice(this.search(/[A-Z]:/[^/]/i)).replace(///g,'\'))
};

String.prototype.folderOf=function(no_slash){
return this.slice(0,this.lastIndexOf('\',this.length-(/\$/.test(this)?2:0))+(no_slash?0:1))
};


There is a [url=http://msdn.microsoft.com/workshop/author/hta/reference/properties/commandline.asp]commandLine[/url] property but I've found it to be unreliable.

@martasauthorNov 26.2005 — umm.... to tell the truth, I did not really understand your code... *ashamed*

I think you got me wrong, though. whatever, here's my code:

fso = new ActiveXObject("Scripting.FileSystemObject");

filename = "data.txt";

file = fso.OpenTextFile(filename, ForReading, false);

rawFile = file.readAll();

file.Close();

//the above one does not work.

//but if I write absolute path in filename:

fso = new ActiveXObject("Scripting.FileSystemObject");

filename = "C:blablaimportantinfodata.txt";

file = fso.OpenTextFile(filename, ForReading, false);

rawFile = file.readAll();

file.Close();

//that works fine

@martasauthorNov 27.2005 — Of course I do. As I said, everything works if I use absolute paths....

That's what I figured. Therefore, what I posted [B][I]is[/I][/B] what you need.

does this help you understand ?

var app_path=location.href.toLocalPath().folderOf();

alert(app_path+'data.txt')
