Here is a quick tutorial on how to create a Guest Book Application using Web Matrix.

This tutorial is a little different than the usual highly polished tutorial. We will show you not only how to create the Guest Book Application with .NET for your website, we will also show you some typical errors that can happen along the way. If we have a simple error in our code, we will let you know about it, and give you advice on how you can figure out how to fix this kind of error. Of course we will show you where the error is and how to fix it. This will help you learn how to solve some of these common mistakes in your own applications.

Prerequisites

You must have a PC running any version of Microsoft Windows since Windows 98. You download the .NET Framework 1.1 and install it on you machine. Then download the Web Matrix Software and install it on your machine. You will now have everything you need to develop simple apps for the .NET framework.

Description of the Guest Book Application

We will start with a very simple guest book application. It will allow users to enter their name, a URL, and a single line comment. The comments will be appended to a simple text file. Our guest book application will have two web pages: a page to display the guest book comments, and a page to enter new comments.

Skills Taught In This Guest Book Application Tutorial

This application shows how to use an event handler to handle the submission of a form, how to use StreamReader?Create and StreamWriter?Create to read and write text files, and some very simple string processing using the Split function. We also discuss some very simple object oriented issues in deciding how to structure the code in our program.

Possible Enhancements To The Guest Book Application

Here is a short list of ideas we have for improving the guest book application:

• Allow longer multiline comments
• Allow the users to enter an email address that is stored, but not displayed in the guest book
• Allow the website owner to edit the comments in the guest book
• Store the guest book entries in a database
