ReadLine Method

Updated: September 2009

Reads an entire line (up to, but not including, the newline character) from a TextStream file and returns the resulting string.


                      object.ReadLine( )

The object argument is always the name of a TextStream object.

The following example illustrates the use of the ReadLine method.

var ForReading = 1, ForWriting = 2, ForAppending = 8;

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

// Open the file for output.
var filename = "c:\\testfile.txt";

var f = fso.OpenTextFile(filename, ForWriting, true);

// Write to the file.
f.WriteLine("Hello world!");
f.WriteLine("The quick brown fox");
f.Close();

// Open the file for input.
f = fso.OpenTextFile(filename, ForReading);

// Read from the file and display the results.
while (!f.AtEndOfStream)
    {
    var r = f.ReadLine();
    document.write (r + "<br />");
    }
f.Close();
Const ForReading = 1, ForWriting = 2, ForAppending = 8
Dim fso, MyFile, FileName, TextLine

Set fso = CreateObject("Scripting.FileSystemObject")

' Open the file for output.
FileName = "c:\testfile.txt"

Set MyFile = fso.OpenTextFile(FileName, ForWriting, True)

' Write to the file.
MyFile.WriteLine "Hello world!"
MyFile.WriteLine "The quick brown fox"
MyFile.Close

' Open the file for input.
Set MyFile = fso.OpenTextFile(FileName, ForReading)

' Read from the file and display the results.
Do While MyFile.AtEndOfStream <> True
    TextLine = MyFile.ReadLine
    Document.Write TextLine & "<br />"
Loop
MyFile.Close
