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.
