Custom Icon for Browser Favorites List When Microsoft introduced what they called the Shortcut Icon for IE5's favorites list, many articles appeared on the Internet about how to create them and use them. Now, not much is heard about them, although information is still to be found on the Internet — provided one knows what to search for. Customizing Emails Your Scripts Send Dear WebMaster, What's New on Your Site? It seems difficult enough to add new content consistently to your site, but needing to let people know "What's New" when they land is another little chore to manage. Designing Consistent Form Field Sizes It can be frustrating to design a form so it looks good, then test it on another browser and have the design fall apart. It is for site owners whose sites are crippled by popup blockers, and those who are otherwise curious about which or how many of their visitors actually do have effective blockers, that this article is written.

Make extra information available to the visitor - on the same page they are viewing Hide and Reveal Content, On Demand: How It Works Hide and reveal content on a webpage. CSS is the key. JavaScript is the switch. Imagine a restaurant that serves many hundreds of thousands of clients every day. Nobody knows how many clients there really are. It might be millions. Or even billions. They're everywhere. How To Make A One-Click Poll for Text Email I'll show you how to make a one-click poll for your outgoing plain text (or HTML) email. Making short URLs out of long ones is a snap with ProLinkz™ and rewrite module lines in the .htaccess file (rewrite module line generator included in the article). HTML Character Codes at Your Fingertips HTML Character Codes (HTML Entities) are the codes that make those useful symbols that I often can't recall how to make. An example is the © code for the copyright symbol character, which prints a "c" in a circle. This article puts the codes at our fingertips. HTML Tooltips With CSS Enhancements You're probably aware that when a cursor hovers over text affected by a TITLE attribute, the value assigned to the attribute shows up as a tooltip.

This article contains notes about what we did and, in one instance, what would have been done differently. Multiple Form Submission Prevention Several methods exist to prevent users from clicking a form's submit button more than once. Their effectiveness ranges from merely alerting the user that the form is being processed to an essentially 100% effective duplicate block. No-Kill Pop Box (Instead of Popups) Today you will learn about a way to present the information previously put in popup windows, yet popup killers can't kill this pop box! A pop box is content within a rectangular area that might or might not be visually similar to a pop-up, but which displays on top of the content of the current web page rather than in a separate window of its own. This article provides the means to use cookies so your No-Kill Pop Box is displayed only once to a visitor for a pre-determined number of days. For any of many possible reasons, sometimes it is desirable to have the browser open a new window for the new page when a link is clicked. One would think counting page loads is a trivial task.

Almost any server task that needs to be done according to a schedule, and doesn't require direct human supervision, can be set up with Unix/Linux cron. When you are viewing a page with an https://... URL and the lock on your browser is closed, it means you have a secure connection to a server. The server on a secure connection is often thought of as a "secure server," but that isn't necessarily true. Secure Servers and Information Security When you are viewing a page with an https://... URL and the lock on your browser is closed, it means you have a secure connection to a server. The server on a secure connection is often thought of as a "secure server," but that isn't necessarily true.

Useful Statistics for Variable Content CGI Scripts When you're on a Unix/Linux server and you want server software to launch at certain times and dates, you use cron. I will show you how to make a file that cron can use. When you need to submit a form to another script without human intervention, this article can get you started. You'll find a browser-emulation script that will submit form field information (that you specify) automatically. Web Page Form Anti-Hijacking Considerations A devious method of hijacking a form is to insert line breaks into form fields that will be used in email headers. After the first line break, the spammer can insert a Bcc: line with a thousand email addresses (an arbitrary number, which could be more or less depending on how many addresses the spammer thinks your server can handle in one gulp). |
