I needed a link control that would display a dotted-underline on hover. To achieve this I overrode the rollOverHandler and the rollOutHandler of a standard LinkButton. Inside the rollOverHandler I used the graphics API to draw a dotted underline beneath the control’s textField. Here’s an example: There are some magic numbers, but tweaking them to […]

Starting with certain versions in the 9.0’s of Flash player, socket communication in Flex began adding additional security measures. The one I am going to discuss in the post is the socket policy file. In short, the socket policy file is an XML file that is served by default from port 843 and contains information […]

Client-server programming is one of my passions, and I enjoy doing it in almost any language. Which makes it fitting that Flex (ActionScript) is one of my favorite languages to develop in, because it truly is a client-side technology which pretty much means it’s open to just about any type of backend server. I suppose […]

I attended a user group presentation on Adobe Catalyst today (2/2/2010), and I thought I’d express some of the thoughts I had, and on code generation in general. This product seems to spark up a lot of debate, and I think it’s because most conversations are only focusing on two roles (designer vs developer) when […]

One of my ongoing weekend projects is an AIR chat application, recently rechristened “JUICE” a.k.a. “John’s Ultimate Internet Chat Experience”. I realize that may only be the case for myself, but the project has been very educational and entertaining for me. The initial release used AIR/Flex as the front-end, ColdFusion and MySQL for the backend, […]

Sean Murphy (my friend and fellow BYU-AUG member) just did a write up of some training he did last month for our user group. It’s an introduction to P2P with Flash+Stratus. In my opinion, this is some really exciting technology as most communication of this sort (for Flash player) has to be routed through an […]

I’m about ready to sleep on my ShortcutManager, I figured I might as well finish off the series. I added context to it, while still maintaining backward compatibility with the non-context enabled version. I don’t think I posted it, so it probably won’t matter so much to my readers. For those who haven’t read the […]

I’ve put some more thought into my shortcut manager, and have decided on a way to implement the shortcut context, as well as curb the Dictionary explosion that my previous architecture would have had. The new version uses one Dictionary to store all functions, the keyCode, combo keys, and context is all encoded into the […]

Strictly speaking, bit strings are not nearly as easy to understand as named boolean variables; but there are situations when they can simplify or eliminate the need for long boolean expressions. Consider my recent post about the ShortcutManager. There are three control keys that may or may not be pressed at any given time. This […]
