Creating Calendars in PHP – Part 2

In this tutorial we look at the advantages of removing HTML attributes from the PHP code and replacing them with CSS classes, so that the whole dynamically-produced calendar can be restyled just by changing the CSS styles and without having to change the code in any way.

We then look at the MySQL datetime field format which stores a date and time in a format which can be easily changed into a timestamp using the MySQL UNIX_TIMESTAMP() command. We look at the advantages of using the Unix timestamp format, such as making it easy to select dates using simple numerical operators and being able to automatically sort records in order of date and time.

Finally we learn how to select all events that fall on a certain date, and then at how to find all records which fall between a range of dates.

Working with the Server's file system using ASP.NET

This tutorial explains how to carry out many common tasks relating to the accessing and manipulating a server file system, including listing files and directories, checking for the existence of a specific file or directory, reading and writing text to text files, copying, moving and deleting files and directories. You will also be shown how to obtain statistics of directories and files such as file size and modified dates. By the time you have worked through this article you will be more knowledgeable about file system access and manipulation using the powerful classes provided within the .NET Framework.

The tutorial covers the following subjects:

• Writing text to a file
• Reading text from a file
• Finding out if a file or directory exists
• Renaming a file or directory
• Copying and moving a file or directory
• Deleting a file or directory
• Listing the contents of a directory
• A hierarchal listing example
• Common problems and errors

We end the tutorial with an example of displaying the contents of a directory using a recursive routine to show the hierarchy of its contents in much the same manner as a tree control would display them.

Building ASP.NET HTTP Handlers

In this tutorial, Chris Ullman shows you how to build your own HTTP handlers using ASP.NET. HTTP handlers can let you intervene and handle a request for a particular type of page, and make it possible to catch URLs that are submitted by a user and rewrite them in a format required by the web site, to disguise long, cumbersome URLs or to process filetypes not gererally dealt with by the server - for example, custom handling of new XML types.
