In the past couple of years it has been common for Flash developers to design elastic sites, rather than sites with fixed dimensions. These elastic sites fill the browser window, and content is positioned programatically on the stage according to the size of the viewport. The trouble with this approach is that because the width and height of the embedded Flash swf are set to 100%, the browser will never display scrollbars. If the user sizes their browser window too small then content will begin to disappear off screen. Due to the lack of scrollbars, this hidden content is inaccessible to the user.

By writing a small JavaScript function that is triggered when the window is resized, we can overcome this restriction. When the window size is detected to be smaller than a minimum width/height specified by the designer, the Flash movie will stop scaling, and scrollbars will be forced to appear.

In a recent post on the Microsoft Internet Explorer blog, Pete LePage announced that Microsoft have released a Virtual PC 2004 image that includes Windows XP SP2, Internet Explorer 6, and the Internet Explorer 7 Readiness Kit. Here’s the kicker: you don’t have to buy an additional Windows license, which was previously the case when running Windows under VPC.

One of the great benefits of PHP is that it is quick and easy for non-programmers to learn the basics of the language and begin to add server-side logic to their websites. This simplicity is a double edged sword, as many novice programmers are unaware of PHP’s security vulnerabilities and inadvertently create web applications that are an easy target for hackers and spammers. Most PHP security holes are well documented, but a newer and lesser known vulnerability is header injection, a cunning exploit whereby a spammer hijacks a website’s contact form and uses it to send bulk unsolicited email.

A recent article by Kevin Yank in the Sitepoint Tech Times newsletter drew my attention to TweakPNG, a handy tool that can correct the age old problem of PNG color shift in Internet Explorer.
