Javascript question

Hello!

I was wondering if anyone knows how to check for the end of file using Javascript and Active X.

I want to perform a while loop using the condition "while not end-of-file". Unfortunately, EOF, eof, EOF(), eof()... do not work at all in Microsoft internet explorer 6.

Here is part of my code:

// This creates a new Active X Object in order to read in a file.
// Refer to the new variable as "file"

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

// Sets the variable "f" to equal the new open file contents

f = file.OpenTextFile("c:\\wantlist.txt", 1);

// This SHOULD keep looping until it reaches the end of the file
// but doesn't!! It actually keeps looping without correctly checking the condition
// until a javascript error pops up saying it's already reached the end of file when it
// tries to read in the line.

while(!line.EOF())
{
line = f.ReadLine();
}

Anyone know the correct syntax for checking an End-of-file for Javascript using Microsoft Internet Explorer 6 and up??

I'd appreciate any help!

You should be able to write the following:

Code:

---

while(line = f.ReadLine())
{
...Do Stuff...
}

I'm not familiar with JavaScript, but this works in almost every other programming language out there. The read should return false when it hits the end of file.

Thanks for the info Deltarra!

I didn't know that such a check works in just about all languages. That'll come in handy!

In addition, I figured out how to correctly check an end of file for this Active X "OpenTextFile" object:

while(!f.AtEndOfStream)
{

}

This works just fine for me.
I appreciate your help Deltarra!
