The web is many things, but here’s one thing for certain: The web wouldn’t exist at all without the hyperlink. We use it to link from page to page, from a web page to email, from a point in a document to another point within that document. We use links to download files from web pages, and to attach behaviours to, as in the case of JavaScript rollovers.

Be honest.
Have you ever trolled around the web to find a design that you like?
Have you ever contemplated stealing the mark-up or styles from another site?
Have you ever tried to emulate a site, but just couldn’t pull it off?
Have you ever played with an existing site just for fun, and found that if you change even one color the whole site looks off-kilter?
The MyDoom virus has been spreading like wildfire in the last 24 hours. Some companies are receiving 1000 infected emails a minute. The virus installs a trojan that can leave the host machine open to sending spam or denial of service attacks before it grabs email addresses off an infected computer, and emails itself on. Reportedly, it records keystrokes on affected machines so can mail off passwords, user names etc to whoever coded it.
The worm uses random subject lines that include "test" and "Mail Delivery System" and carries different text messages, including: "The message cannot be represented in 7-bit ASCII encoding and has been sent as a binary attachment." The attachment names also vary, having ".exe", ".pif", ".cmd" or ".scr" as extensions and are sometimes compressed as a Zip file.

In our tutorial last week, Graphing with PHP, we started building a class that you could use to draw a graph using the PHP Image functions.
We used a simple data holding object that contained all of the data that we needed to draw our graph, and then passed that to a graph drawing script by storing the data temporarily in a Session variable on the server. This method allowed us to use our PHP image drawing scripts as the SRC of an IMG tag so that the dynamic graphics could be embedded within an HTML page.
Sooner or later you’re going to have the need for a user to fill in a field with a date. It’s like Murphy’s Law, it’s inevitable. In any event, one nice way of handling the situation is to provide some kind of widget to allow the user to pick the date instead of having them type the date in manually. Typing in dates manually can often be a problem, especially with a global medium like the web; Americans write 3 January 1/3; Europeans write 3/1. Are your dates 03/01/04? 3/1/04? 1/3/04? 1/3/2004? A date picker, when a user clicks on a date from a calendar-like interface can smooth the process.
We're going to build a form for a website that will automatically email the form's contents to one of a range of email addresses, depending on a radio button selected by the user. I show you how to build this using Dreamweaver MX 2004, and supply the ASP code, and then we examine it to learn how it works. We examine the differences between the GET and POST methods, server-side valiadtion of the form - and when client-side validation with JavaScript is better.
