problem with 'Scripting.FileSystemObject'

[Bogey]

Hi ,
I tried to write a Line at the end of my file Test.txt.

[HTML]function AddNewL(){
var Object = new ActiveXObject('Scripting.FileSystemObject'); var LirTxt2 = Object.GetFile("F:\Test.txt");
var ForWriting=2; //to be able to write
var doc2 = LirTxt.OpenAsTextStream(ForWriting,true); doc2.WriteLine("byebye); //
doc2.Close(); //close the file
} [/HTML]


But I can only manage to overwrite and i loose my first lines.
If someone has a good idea,
many thanks

You need to read the txt file first set the previous text to a variable then write it all back as one other than that I don't use FSO in my javascripts security problems with it.

I am not sure to understand correctly,
[HTML]
function AddNewL(){
var Object = new ActiveXObject('Scripting.FileSystemObject'); var LirTxt2 = Object.GetFile("F:\Test.txt");
var ForReading = 1;
var myText = LirTxt2.OpenTextFile("F:\Test.txt", ForReading);
myText = ts.ReadLine();
var ForWriting=2; //to be able to write
var doc2 = fso.OpenAsTextStream(myText,true); doc2.WriteLine("byebye); //
doc2.Close(); //close the file
}[/HTML]

It did not work.
Please can you explain it again.thank

doc2.WriteLine("byebye); //
 
Needs to be
 
doc2.WriteLine("byebye"); //
 

function AddNewL(){
    var Object = new ActiveXObject('Scripting.FileSystemObject');     var LirTxt2 = Object.GetFile("F:\Test.txt"); 
                var ForReading = 1;
                 var myText = LirTxt2.OpenTextFile("F:\Test.txt", ForReading);
                 myText = ts.ReadLine();
    var ForWriting=2; //to be able to write
var doc2 = fso.OpenAsTextStream(myText,true);     
doc2.WriteLine(myText+"byebye"); // 
    doc2.Close(); //close the file
}

Congratulation i_am clint ,
Your solution is great .
You saved my day.thanks

I think you were using the wrong Const;
ForReading = 1
ForWriting = 2
ForAppending = 8

you wanted an 8 and you were using a 2. try an 8 and your original shorter code should work fine.

You are rigth Sageman, Thanks
with 8 it's working
