Every programming language does it a bit different. Every programming language supports it somehow. Talking about "carriage return" + "linefeed". Especially in a multi language environment like FLEX (FLEX + Actionscript + Coldfusion | JAVA | .NET) it can easily happen that language constructs get mixed up. Yet it is important to break lines in column headers, alerts, labels, and so on.
One of Flex's little joys is the great client-side validation options you have. We've put together an example of extending the Flex mx.validators.Validator class to validate the Australian Tax File Number. It should be a good example to get you going on any sort of custom validation.
In almost every type of web application we have to collect user details. One of those user details is information about 'countries' (origin, residential address, postal records). The following sample code creates a mx:ComboBox and populates it with all (well, most) countries. Note the handy 'selectedItem' method in the mx:ComboBox class ;-)
The first part of a series building FlashPaper into your Flex application. We find it tremendously useful for large printable docs, reports and the like to keep the document inline and not force the user to pop up a separate window just to print.
Martin Ollman passed me this superb graphic representation of what I like to call the "RIA Evolutionary Timeline". Actually in truth I call it something like, "the whopping, great big, unprintable graphic about Flex positioning" -- but you get the gist.
Though it doesn't say anything new, its good to see sites like O'Reilly's onJava.com talking about products like Flex. Despite sales success general support for Flex from Java heavyweights IBM seems to have been slippling.
Flex is not so much about rapid Flash development (although this is one of the advantages) as it is about collaborative Flash development. Flash IDE, the FLA, and everything about it is the bane of largescale development -- it sucks. This is why Flex had to be built.
Credit goes to Darren Tracey who observed on CFAussie (http://lists.daemon.com.au/cgi-bin/lyris.pl?enter=cfaussie&text_mode=0&lang=english) that Flex has been released (http://www.macromedia.com/software/flex/), there's trial available and the DevNet Center is up and running too (http://www.macromedia.com/devnet/flex/).
Not only did we get a great sneak peak of Flex at the keynote of MXDU day 2, many many thanks to Tim Buntel and Ben Elmore for the fantastic tag team event, but I'm now wondering if we didn't unknowingly get a very early look see at the Flex logo. I just did a quick check of the Flex home page at Macromedia and see nothing there so...
With the announcement of Macromedia Flex (previously code named Royale) and MXML Macromedia have managed to reveal just how on the ball they really are. All the excitement about Microsoft's Sparkle for Longhorn has been wasted - here's something that's OS/hardware/platform independant - why it'll even work on a mobile device! And as for the markup...
