Working with the TextStream Object
Reading from a file is also very straightforward via
the power of the TextStream object. You can see how this is done
with the following code, using the TextStream object's properties and methods.
<html> <title>Working with the File Object</title> <body> <b>A second example of working with the File object!</b> <hr> <% set TestFile=Server.CreateObject("Scripting.FileSystemObject") set TFileStream=TestFile.OpenTextFile( "c:\inetpub\wwwroot\ASP_Examples\TestFile2.txt") TextFormat=TFileStream.ReadLine %> <p> <font face="Century Gothic" size="5" color="#008000"> <i> <%=TextFormat%></i> </font></p> </body> </html>

The capability to read from an existing text file enables you to draw on all kinds of additional information resources when developing in ASP.
As you can see in this figure, the preceding code opens the TestFile2.txt file for reading. Then (through the power of the ReadLine method) the code reads the first line of text from this file, Welcome to the File Object in ASP!. Remember from the description of the ReadLine method, the data returned is set to a string. Keeping this in mind, you set the value of the ReadLine method to the variable TextFormat. Finally, before outputting the contents of this variable to the screen (via the line <%=TextFormat%>), you apply some general HTML formatting. I set the font to Century Gothic, assigned a bigger font size, and italicized it. This formatting gives the text (as read from the file) its unique appearance, as shown in the figure.
