Often when learning design, imitation can be the best form of education. I recently had an email from a regular reader asking if I could show her how to create an effect she’d seen on the music inspired clothing line website LyricCulture.com.
This page describes how to get the value of URL parameters such as ?id=5432 that have been passed to your webpage in the URL, usually by a form that has been submitted. Maybe the URL requested was:
1. Open Corel DRAW. Draw Rectangle with Rectangle Tool. Note: It is expected that you have finished with the beginners and intermediate projects when you start with advance, as we do not repeat the small instructions.
The first part of an if statement-the part between the parentheses-is the conditional expression associated with the if statement. This conditional expression is just like any other expression you've seen so far; in fact, you can use any legal Perl expression as a conditional expression. When the Perl interpreter sees a conditional expression, it evaluates the expression. The result of the...
nvoke a save, either with alt-F S, or with F2. There is no "Save As", as such, in Turbo Pascal, but the first time you save something, you are given a chance to designate a name for the file. (The equivalent of "Save As" is on the file menu, as "Write to".) You could just enter "My Program" in the file name box and click "ok", but I'm going to...
The write(lcd,255) line clears the LCD screen. If you said write(lcd,65), an A would appear on the screen, 65 being the ASCII code for "A". Notice there are no apostrophes around the 65. If you wrote write(lcd,'65'), then you would get 65 on the LCD. 255 is what programmers call a rogue value. It is special; it isn't treated like other numbers. Its meaning to the LCD unit is "Clear...
Final Gathering - Final Gathering is computed from the point of view. When the primary ray hits the point on an object, final gather is activated and a series of rays are diverted at random angles into the scene to calculate the light energy (colour information) to be calculated around the point for which we are computing colour for.
Now we are ready to create our very own Address class. Let's start simple. Let's start with an address that only contains the "street" field.
Hashes are a generalization of arrays. Instead of only permitting integer indices, as in array[3], hashes allow any object to be used as an "index". So, you can write hash["name"]
AIM profile designs provide us with new possibilities. And this Aim Profile Screenname Viewer tutorial will show you how to make a script to see who has seen your AOL Instant Messenger profile.First, make a file called "sn.html" inside a folder (I've chosen my database folder even though this is a flat file). Leave it blank. Be very attentive while making changes to AIM profile...
UNDERSTANDING HOW PROGRAMS WORK IS ONE THING. Designing a program to perform some particular task is another thing altogether. In Section 3.2, I discussed how stepwise refinement can be used to methodically develop an algorithm. We can now see how subroutines can fit into the process. Stepwise refinement is inherently a top-down process, but the process does have a "bottom," that is, a...
In this Photoshop tutorial we’ll be experimenting with layers and styles to create a cool glowing orb and dial effect. This tutorial is written with an intermediate to advanced user in mind but I think anyone who knows their way around Photoshop shouldn’t have a problem reproducing this effect.
Most database management systems provide easier and faster ways of extracting information from their tables. The common denominator of these methods is SQL, the Structured Query Language built into these systems. SQL is a full-service language for maintaining information in a database and worthy of study in its own right. However, we'll pick and choose the features as we need them rather than...
Have you ever wanted to bring attention to a specific area of your design, possibly an area that is very detailed? With this tutorial, you'll learn how to magnify a design!Start off by opening a design you'd like to work with. Then choose a shape you'd like to use for the magnify area. I chose an ellipse. With the Ellipse Tool, I drew an ellipse and placed it over the area I would like to magnify.
Forgive a nostalgic digression? As I start this tutorial, I must just pay homage to Per Ranhoff. I can remember extraordinary detail of a day in the late sixties when I age 15, I was sitting in my first computer lesson. Per started us off with the concept of variables. The specific machine he was showing us how to use was the same PDP-8 that he- who- would- become technical director of "Toy...
