<p class="intro">The TextStream object is used to access the contents of a text file.</p>
<hr />
<h2>Examples</h2>
<p><a target="_blank" href="showasp.asp@filename=demo_readtextfile">Read textfile</a><br />
This example demonstrates how to use the OpenTextFile method of the FileSystemObject
to create a TextStream Object. The ReadAll method of the TextStream Object
reads from the opened text file. </p>
<p><a target="_blank" href="showasp.asp@filename=demo_readpartoftextfile">Read only a part of
a textfile</a><br />
This example demonstrates how to only read a part of a TextStream file.</p>
<p><a target="_blank" href="showasp.asp@filename=demo_readline">Read one line of a textfile</a><br />
This example demonstrates how to read one line from a TextStream file.</p>
<p><a target="_blank" href="showasp.asp@filename=demo_readlines">Read all lines from a textfile</a><br />
This example demonstrates how to read all the lines from a TextStream file.</p>
<p><a target="_blank" href="showasp.asp@filename=demo_skip">Skip a part of a textfile</a><br />
This example demonstrates how to skip a specified number of characters when
reading the TextStream file.</p>
<p><a target="_blank" href="showasp.asp@filename=demo_skipline">Skip a line of a textfile</a><br />
This example demonstrates how to skip a line when reading the TextStream file.</p>
<p><a target="_blank" href="showasp.asp@filename=demo_line">Return line-number</a><br />
This example demonstrates how to return the current line number in a TextStream
file.</p>
<p><a target="_blank" href="showasp.asp@filename=demo_column">Get column number</a><br />
This example demonstrates how to get the column number of the current character in a
file.</p>

<h2>The TextStream Object</h2>
<p>The TextStream object is used to access the contents of text files.</p>
<p>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):</p>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<td valign="top"><pre><%
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
%></pre>
</td>
</tr>
</table>
<p>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.<p>The TextStream object's properties and methods are described below:</p>
