The TextStream Object

The TextStream object is used to access the contents of text files.

The following code creates a text file (c:\test.txt) and then writes some text to the file (the variable f is an instance of the TextStream object):

<%
dim fs,f
set fs=Server.CreateObject("Scripting.FileSystemObject")
set f=fs.CreateTextFile("c:\test.txt",true)
f.WriteLine("Hello World!")
f.Close
set f=nothing
set fs=nothing
%>

To create an instance of the TextStream object you can use the CreateTextFile or OpenTextFile methods of the FileSystemObject object, or you can use the OpenAsTextStream method of the File object.

The TextStream object's properties and methods are described below:
