I was honored to be asked by ComponentArt to participate in a judging panel for their just now released 2009 Summer Silverlight Coding Competition.  The grand prize is USD $10,000.  Yes, that’s right: USD $10,000! ComponentArt is even kicking in 2 runner-up prizes of licensing to their products, which is also a sweet deal!  The contest is simple, and you are not required to use ComponentArt controls…in their words: Applicants are not required to use ComponentArt's products to enter the competition (or as the legal jargon requires us to say: NO PURCHASE NECESSARY). We'll obviously let you use our products...

Today, we posted on the .NET RIA Services forum an updated roadmap for the timing and thoughts around the product offering.  What is .NET RIA Services? Microsoft .NET RIA Services simplifies the traditional n-tier application pattern by bringing together the ASP.NET and Silverlight platforms. The RIA Services provides a pattern to write application logic that runs on the mid-tier and controls access to data for queries, changes and custom operations. It also provides end-to-end support for common tasks such as data validation, authentication and roles by integrating with Silverlight components on the...

One of the goals of new versions of Silverlight is to be be backward compatible with previous versions.  We make this a priority goal so that people can keep their previous applications deployed while not worrying that people with newer Silverlight will have a broken experience. Silverlight 3 has been out in beta form since March 2009 and hopefully if you are a Silverlight developer you’ve had a chance to work with the new features and tools.  If you have existing Silverlight 2 applications that are deployed, I wanted to draw your attention to some action items if you...

At the Google I/O conference this past week, they announced Google Wave.  Almost immediately, I started seeing Twitter replies, blog posts and various articles talking about how Google Wave is going to kill Flash/Silverlight/JavaFX.  None of these made sense to me…and at that point I’d yet to see anything about Wave anyway.  I posed a few questions on Twitter as to why people felt Wave was an RIA platform killer (that’s what I was reading into a lot of the buzz against things like Silverlight).  I got more confused with all the replies :-).  So I had a moment this...

If you looked at the updated RIA Services Business Application template which had the authentication built-in, you may have seen the login screen with a little icon next to the password field: When you hover over this some helpful information displays in tool tip form: So how did that get there?  The power of the data annotations.  If you look at your model definition, you can add a DisplayAttribute and provide some additional information.  Let’s take a look at a simple example.  Here’s the simple model: ...

Well today was the public release of Visual Studio 2010 Beta 1.  It is the first time developers will have the chance to take it for a spin and kick the tires.  I wanted to share some information specific for Silverlight developers with regard to Visual Studio 2010 Beta 1. Visual Studio 2010 is the first IDE that will support two key features for Silverlight developers: multi-targeted Silverlight development and editable design surface for Silverlight.  The second point also comes with things you might expect (like data binding wizards and dialogs as well – I’m lumping all of that...

I’ve not hidden my love affair for Netflix both as a consumer and as a Silverlight developer and how they’ve implemented the technology.  Long before the instant watch came to the desktop and the XBOX, there were a lot of folks wanting the Netflix experience on their Windows Media Center boxes and extenders.  One such person was Anthony Park (who is now with Netflix as of this writing), who picked up a the MyNetflix media center plugin a while back. Well, today Netflix officially has a Media Center solution for their customers.  I just got done firing my media...

For things that aren’t a part of the Visual Studio tools (yet) and things that help me move faster in my development, I like to take advantage of the power of Visual Studio’s templates and snippets capabilities.  I’ve created a few and modified a few of others that I use regularly.  I’ve shown them in a few presentations and thought I’d package them up in a single bundle for your convenience if you choose to use them.  I was going to package Robby’s snippets up as well, but didn’t think he’d appreciate that…you should get his Silverlight snippets as well...

We’ve update the .NET RIA Services build for May 2009.  The updated May preview can be downloaded here: .NET RIA Services May 2009.  You may have to uninstall your previous version before installing this one.  What is .NET RIA Services? Microsoft .NET RIA Services simplifies the traditional n-tier application pattern by bringing together the ASP.NET and Silverlight platforms. The RIA Services provides a pattern to write application logic that runs on the mid-tier and controls access to data for queries, changes and custom operations.

I’ll be joining Dan Wahlin and Rob Bagby on 18 May in Phoenix for a Best of MIX event.  I’ll be presenting Silverlight 3 and building data-driven line-of-business applications.  All demo, all tech, all Visual Studio as my presentation tool :-). Come out and join us for the event! Best of MIX Agenda Monday, May 18, 2009 1:00 PM - 5:00 PM Wells Fargo Conference Center 100 West Washington Street, MAC S4101-017 Phoenix Arizona 85003 What’s New in Silverlight 3? ...

We’ve just released an update to our Silverlight Enterprise Deployment guidance/whitepaper.  While a lot of the information from the first version of the guidance (targeted at Silverlight 1.0), we made some minor adjustments outlining the specifics for the updated Silverlight installer and documented some of the command-switches and their behaviors.  The guidance covers: Using Windows Software Update Services (WSUS) Group policy Microsoft System Center Configuration Manager (SCCM) Manual install options Maintaining and detecting version It’s a great guidance document to...

I’ve seen a few comments/requests incoming lately that people like the ChildWindow control in the Silverlight 3 SDK.  This is a great control that creates a modal dialog for you.  When you use it, it disables your root layout application and shows the dialog you provide: This is great for those true modal needs.  It responds to normal windows DialogResult type responses if you have buttons, etc. – great for error dialogs, logins, etc.  The request I’ve been seeing is for the same functionality, but in a ‘normal’ ChildWindow. But I’ve been seeing requests that it should act more like the normal...

What do you get when you invite 14 companies for 3 1/2 days and throw a bunch of new stuff in their face and ask them to use it?  Well, in Wellington, it was called Expression for Art’s Sake.  This was a bit of an ‘artist in residency’ program where Microsoft invited some companies to bring their developer and designer staff to this event to learn a little bit about Expression Blend and Silverlight.  Coming after WEB09 and ending our Auckland trip with a proper visit to a rugby game (here’s a scrum meeting for you agile developers),...

Last week I was wanting to do something on my site sort of a ‘breaking news’ style banner that would span the entire site width but only when I wanted it too – based on a cookie or something else.  And I didn’t want to do something server side, because I was sick of doing stuff like that. Not having played with jQuery, I thought I’d take a dive.  Prior to MIX09, I’d been testing something that the MIXOnline team had been toying with, which has just been released: Glimmer.  Glimmer is described as a jQuery Interactive Design Tool. ...

It’s that time of year my friends in Arizona.  No, I’m not talking about when the air conditioners start get turned on, nor how the golf green fee rates are reduced or the snowbirds fly away…although those are good things as well. I’m talking geek fest time.  Mark your calendars: 26 May 2009 – 8:00 AM The community leaders in the area have organized another big event for your benefit.  So who is coming?  Here’s the rundown: Glenn Block – come see why you should get addicted to MEF.  Don’t know what it is?  That’s...

There seems to be a lot of buzz around Silverlight lately and I admit, I like it :-).  But I also think that there is a huge misconception about Silverlight “replacing” WPF.  I get emails a lot about people asking me questions about Silverlight and after a bit of prodding, I see that their target platform for their application is Windows.  I then begin my rant on why it should be WPF if that is the target platform.  I’m usually met with some weird looks being that I do a lot of Silverlight, but I state my case accordingly. The...

I’ve been promising this for a while and I’ve ranted about creating good installation experiences for Silverlight applications before as well here and here.  Well, our team rallied and created some new guidance and sample code to provide for you to implement the best possible experience.  The guidance whitepaper can be found on the Silverlight Community Site in the whitepapers section and includes: Documentation for defining a good user experience Sample code for media applications Sample code for non-media applications Sample code for implementing various states: not...

I got this question on how do you add grouping to the DataGrid in Silverlight without using the RIA Services ObjectDataSource.  Frankly I didn’t know off the top of my head either and I’ve since learned it isn’t obvious.  Allow me to explain the steps. In my simple app I have a static class that supplies some hard-coded data: 1: public List<Person> GetPeople() 2: { 3: List<Person> peeps = new List<Person>(); ...

I’ve been playing around with the Silverlight 3 navigation framework some more (thanks for the comments/thoughts on the last post about sharing data).  I got a few emails about understanding how the navigation works and people coming up with interesting uses.  Let’s take a moment to explore two of these concepts: out-of-browser navigation and controlling your navigation in your app. Navigation Basics If you are using Visual Studio 2008 and the Silverlight 3 tools, you’ll notice that when you choose to create a new project (or perhaps you didn’t notice and this will be new to you) that...

If you are like any other developer, including me, you probably disregard most warnings and are usually the same type that keeps clicking next when installing things without paying attention to detail.  That’s okay I do it too. In the release of Silverlight 3 Beta, we noted that this is a developer release and that no “Go Live” licensing was going to be available for this release.  What this means is that we don’t recommend putting things in production as we’ve not exposed or wired up the end-user runtime for Silverlight 3.  The only way people can view Silverlight 3 content...

One of the new features in Silverlight 3 is providing an application navigation framework via the Frame and Page controls in the APIs.  If you saw my guide to Silverlight 3, you may have seen the section on navigation which describes the functionality and as well has a link to a video tutorial about it. I wanted to augment that tutorial with some additional information about URI routing, which I think is one of the great features of the framework.  You see typically your UriMapper might have a 1:1 mapping and look something like this (note in my sample here I’m...

Wednesday at MIX09 was a great day.  I was exhausted, but after the keynote I was so high on excitement it was great.  Throughout the day Twitter was buzzing (or is it fizzing?) about all the news around Silverlight 3.  In one conversation around the out-of-browser experiences with Silverlight, I caught a conversation on Twitter about it with questions about the update model.  I jumped in which resulted in this twittersation (sorry, couldn’t resist): So, instead of trying to cram it in 140 characters, I’ll explain here how it works, and take the liberty of using just slightly more than 140...

Well, by now the interwebs are getting busy with the news about Silverlight 3 details announced at MIX09.  The team has been hard at work (and still aren’t resting) pushing out this beta release.  Over the next week you’ll see lots of blog posts by team members and Silverlight MVPs who have been enthusiastically waiting to share what we’ve been working on and show you some sample applications they’ve been working on.  Quite frankly, so will I :-). But in the meantime, allow me to share my thoughts and perhaps some deeper details with you if you can’t discern them in...

The other day I was given a peek at a company who implemented a full-frame Silverlight application that when I saw it it was one of those “wow” moments.  A lot of the public-facing Silverlight examples are very different from one another and sometimes you see some that are full Silverlight applications that really give you a glimpse of how people are thinking about using the platform and how creative you can get.  Colaab is one such example that I saw at PDC last year (check it out if you haven’t). Another example is a recent one called SnapFlow. ...

If you are a developer who likes various aspect of testing in your application (beyond the “does it work” testing), you may be interested in a few frameworks for Silverlight. Microsoft Silverlight Unit Test Framework This testing framework was developed by Jeff Wilcox of the Silverlight Toolkit fame among other things.  This test framework is used by the Silverlight Toolkit team themselves (as is what is shipped with the source code for the project).  This framework runs unit test inside the browser and includes the ability to test rich controls as well as the entire Silverlight platform. ...

Our team is working on a new design for the Silverlight Community Site and one of those aspects includes a new media experience for the online media/video portions of the Silverlight, Windows Client, and ASP.NET sites.  Today we rolled out the new experience first on the Windows Client community site.  It’s a subtle update but hopefully a welcome one. The older experience was a basic playback experience and was a Silverlight 1.0 application.  This update brings a few new things, but primarily is a Silverlight 2 player with some fun features to engage the viewer.  We’ve added some new...

Did I mention I’m going to MIX?  Will I see you there?  I could imagine that some have tight travel budgets, training budgets shrunk, yada, yada.  I’m telling you…if you are a Microsoft developer in the web and WPF space, you need to be at MIX09.  In an effort to help there are a bunch of ways to reduce some costs…here’s some: Register before 27 Feb 2009 with RSVP code: MIXLastChance and get $300 off the registration fee Share a creative picture about Internet Explorer (details and post yours here) and get...

I received a comment regarding the new Expression Encoder SP1 Silverlight player templates and how they can be used within your own application.  Right now the templates appear to stand on their own.  That’s only because the output of an Encoder action will be an encoded file, the template you chose (XAP) and an HTML page to host the Silverlight player application. But what if you already have an application and are trying to integrate media playback within it?  How can you take advantage of the Encoder templates, but just drop them in your existing application?  Let’s take a...

Today at Microsoft PDC, Scott Guthrie demonstrated some of the new controls that have been provided as a part of the Silverlight Toolkit.  The Silverlight Toolkit was what was previously named the Silverlight Control Pack in the press release when the runtime was released.  This toolkit provides a set of controls and themes for Silverlight 2.  In this initial release, they are: AutoCompleteBox Chart DockPanel ...

This week I had the privilege of attending and helping with some Silverlight in casual games presentations at the XNA Gamefest conference happening in Seattle.  I say helping because the real game experts were there. Two Silverlight presentations were given.  One by Bill Reiss/Joel Neubeck and the other by Mike Snow.  Between the two sessions we covered concepts in Silverlight game development as well as a walk-through of starting out to create a simple game.  I consider these guys to be the foremost experts on the topic given their experience in creating games like Dr. Popper, Stack Attack, Zero...

One of probably the coolest casual ‘games’ I’ve ever seen is Line Rider.  It’s a fun game, but really gets exciting when you have an artist behind it.  Basically it’s a blank canvas for you to draw a route for the main character to hop on his sled and ride.  Sound lame?  Not when you see what some have come up with.  For example, here’s a very popular ‘ride’ on YouTube. Well, the Line Rider team has recently modified their beta version and implemented in Silverlight 2!  They’ve also added some social networking integration using Live Messenger and the ability to...

I suspect we’ll be seeing more of these efforts for Silverlight and I love it.  In fact, INETA will be sponsoring the 2008 INETA Silverlight Challenge soon, so you should sign up for more information about that as well.  But until then… But until then, check out what some of the community MVPs and leaders are doing on their own!  They’ve started the Silverlight Control Builder Contest ‘08.  Two main organizers (Page Brooks and Dave Campbell) have put some time and thought into how they can get the community excited about developing solutions for the community and alas...

Over the past few months Joel and I have been back-and-forthing modifications to his original great idea and goal “build a re-sizable video player using no custom user controls, but instead leveraging controls styles and templates.”  Joel started in Silverlight 2 Beta 1 and implemented using the style method (aka ‘the MIX model’) available at that time.  I took it and added some functionality of scaling and startup parameters.  After the VisualStateManager model for styling was released, this project made perfect sense to demonstrate those abilities and thus I transformed the great styling work that Joel did into the VSM...

I’ve been a Wells Fargo customer for a long time.  As a financial institution it has served me well.  I’ve never really put much thought into the services I use and the interactions I have with their systems.  Actually I take that back – I make heavy use of the online banking system and have noticed some likes/dislikes, but overall pleased. Over the past year, the automated teller machines (ATM) have undergone some design changes that, while subtle, have been impressive and welcome additions to the ATM experience for me.  It really made me actually notice a change in...

Well today (17 JUN 2008) will be the release of Firefox 3, a seemingly much anticipated browser update.  I checked out an earlier build (I think beta 2) and it was a nice browser.  I’m not a browser zealot, I use what works for me and IE works for me, has some tools that I like, etc.  Firefox is a fine browser as well and I do use some plugins from time to time in my Firefox install. Today, I assume a lot of people will be downloading FF3 whether by explicit choice or by a prompt from their FF2 browser...

I’ve just finished updating my modification of Joel’s original concept.  Joel had a really great base for me to build off of and used styling and templates to create simple controls for a standard Silverlight media player that could be embedded.  I took his sample and made some minor adjustments to accommodate automatic sizing as well as make it a bit more parameter-driven.  The end result was (what I think at least) a fairly nice player that could be flexible if needed: Joel made great use of styling primitive controls to be able to leverage core...

One of the things I love about the Microsoft developer ecosystem is the partner channels that are enabled to create great add-ons to our platforms and frameworks.  Our partners in this space usually get to the better implementations before we do, taking on the task of filling some gaps in unique implementations while our teams can focus on providing the best framework for enabling that construction. In December of last year, Telerik showed their intentions of making a control suite for Silverlight (then v1.1).  Well now that beta 2 is released for Silverlight 2, they’ve updated their RadControls for...

I’ve been getting a few notes on issues relating to people trying Silverlight beta 2 and WCF or other services.  The most common issue I’m seeing reported is “my exception is showing a 404-not found error message, but the service is there and works!” Okay, there could be several things happening here, but let’s tackle the “make sure it is plugged in” type situations.  I don’t mean to make light of the error, because at first I, too, was banging my head against a wall.  Sometimes it helps to have a second set of eyes or a deeper understanding...

Now that beta 2 is out and some of the features or more solid, and a majority of the breaking changes have been announced, there is no excuse to hold back anymore.  Oh yeah, and there is a commercial go-live license available now, so no more excuses :-). So where to get started?  Well you should first head over to the Silverlight community site and visit the Get Started section.  There you will find a rather simple formula to get started: Download/install the tools ...

Well, I have about 3 hours until I leave this little city called Mexico City.  Sarcasm of course, did you know there are roughly 25 million people in Mexico City.  I didn’t.  It is amazing.  Traffic, however, is something to be desired.  I’m told that a 3 mile trip at times could take 1hr, 30 minutes.  Maybe I should stop complaining about my commute when I do it?  No, it still sucks. Anyway, on to business.  Yesterday I attended and spoke at the MIX Essentials Mexico conference.  These events are happening worldwide and if there is one coming up...

Um.  Whoa. Okay, DevExpress rocks.  I think this will be very well received by the community and you’ll have to watch their page for when it is available and to get your license. From their site: As the release of Silverlight draws near, DevExpress has invested the engineering resources needed to deliver a feature-rich grid control for Silverlight. Not just a "preview" of what is possible with Silverlight, the AgDataGrid Suite was developed to fully exploit the power and flexibility of the platform… It looks like it will support pretty much everything you’d expect in a DataGrid and more…wicked cool.  Congratulations and thank you...

Silverlight 2 brings a suite of controls for designers and developers to leverage within their applications.  With the Expression tools helping us to be able to skin these controls, also comes some new controls you may not have used yet as well as a new one introduced with the latest release of Silverlight 2. Introducing TabControl. UPDATE: Video walk-through is now live. The TabControl is implemented in the System.Windows.Controls.Extended class library and not in the Silverlight core.  To use it make a reference to the Extended assembly and it will be available to you.  In Expression Blend you’ll see TabControl in the Custom...

If you’ve heard the news about Silverlight 2 Beta 2 and Expression Blend 2.5 (June 2008 preview), you will notice something else in addition to being able to skin your controls easier.  Remember how you may have had to create different states for your element using “MouseOver State" and then create storyboards to transition to states?  There’s now a better way. Enter VisualStateManager. Let’s take a look and see if we can simplify this down a bit a basic understanding.  Let’s use something that most everyone should be able to relate to with states: Button.  A button has...

This week I’ll be traveling to Mexico City to meet developers and designers at the local MIX Essentials (English translation here – funny that RIA gets translated to LAUGHS) event.  I’ll be presenting two sessions there this week.  I was fortunate enough to be asked to kick-off the conference talking about building RIAs with Silverlight 2.  I’m particularly excited about this as I have some things to show that haven’t really been shown broadly yet.  I will also be speaking on working with data in Silverlight 2 later in the day.  This session will cover working with services, servers,...

I just finished up a day attending the Chicago RIApalooza event in, well, Chicago.  First, I must say that I love cities with great mass transit systems.  I’ve said this before and I keep threatening myself to move to one. For this event I paired up with a super designer Corrina Barber.  Corrina works as a user experience designer at Microsoft, is wicked smart and was a perfect compliment to this event.  Most of the attendees at RIApalooza I believed to be interactive developers, so most having a knack for design.  I figured rather than a developer...

Taking another cue from some great stuff Joel is doing, I liked his implementation of the ‘Leopard Screen Saver’ but wanted to make it more ‘real’ for me.  So I wired it up to my Flickr account.  Result here (using Silverlight Streaming): I only had to change a few things. First, in the Page_Loaded event, I removed the timer start function.  This was because with interacting with Flickr it was going to be async.  I didn’t want the timer to start until I knew the image collection was built. My BuildCollection function now looks like this: private void BuildCollection() { // get...

A while back the team at the New York Times newspaper produced a digital reader for their content, dubbed ‘Times Reader.’  The technology powering that reader experience (“the digital newspaper that reads like the real thing”) is Windows Presentation Foundation (WPF), part of the .NET Framework.  It is a remarkable experience for viewing digital news in a traditional format.  It provided online and offline reading capabilities mixed with some new and innovative ways of viewing related stories. Portions of the reader were even transformed into a starter kit framework: Syndicated Client Experiences Starter Kit.  This kit provides the initial...

I’m very excited to have the opportunity to attend the RIApalooza event in Chicago in a few weeks (31 MAY).  What is RIApalooza? RIApalooza promises a platform agnostic and "PowerPoint-Free" zone, which means we are going to forgo the boring marketing pitches in favor of talking technology. RIApalooza is about creating Rich Internet Applications; how to go about building them and what is being built.  source: riapalooza.com I love the PPT-free zone aspect of it.  I loving having the maximum time to show some real working code, answer questions and see what...

Want a Silverlight-branded XBOX console?  Yeah, me too, that would be cool.  Well, there isn’t one of those, but there is a chance for you to show your Silverlight prowess and win some cool stuff. The RIA development portal at DevX is currently running a contest (which ends next week, yikes, hurry!) for creating games in Silverlight 2.  The contest seems relatively simple: Step 1: Create wicked cool game in Silverlight 2 Step 2: Host it on Silverlight Streaming How simple is that…oh yeah, except for the ‘creating game’ part.  There are a few...

There are some really great application concepts emerging using Silverlight.  I cam across two that I feel are really demonstrating great use of the technology, both in the code as well as attention to detail in the user interface.  Both of these examples make great use of layouts, controls, etc. within Silverlight 2 to show what is possible with some imagination and the platform. The first is the “My Travel Management” site which leverages real travel information to represent the scenario of looking at flight arrangements.  It definitely is a twist on the Silverlight Airlines, providing a little more...

I know ScottGu already did a good sample showing integration with Digg and Silverlight, but check out what Jose did! Jose does a great job explaining each of the components here and what he is doing to develop this application.  A good experience demonstration with a lot going on there with Silverlight.  I really encourage you to check out this read and subscribe to Jose’s feed – he’s what I’d call ‘wicked good.’ tags: silverlight, jose fajardo, cynergy, digg, wpf, xaml, ria

got an email today about something i hadn't seen yet, another silverlight 2.0 game, Pirates!  cameron emailed me about a cool prototype he's working on with the farseer engine.  here's a shot: as cameron puts it: "The goal of the game will be to attain the buried fortune of a long dead pirate named Rough Hand James. He created a map to his treasure and scattered the pieces all across the globe. It will be your adventure to find those map pieces and locate the treasure. You will start out on your ship with the first clue to the treasure and...

sure enough as i told the denver visual studio user group last night that the only reason i was still running visual studio 2008 beta 2 was because the silverlight tools had not been updated yet.  check my email later...they are updated :-). the silverlight tools for alpha have been updated to work with visual studio 2008 release version (now available).  you can download the updated bits here.  i'm headed up to redmond for the silverlight firestarter event on thursday and maybe to heckle jesse a bit :-).  if you are going to be in town, drop me a line (my...

one of the things interactive developers sometimes (especially with new technologies like silverlight, flex, etc.) have to worry about is 'what if the end user doesn't have XYZ installed?' -- something that is likely going to be a question when implementing something so new like silverlight. in silverlight, if the user doesn't have the plugin installed, they are presented with a 'get silverlight' badge.  it really doesn't explain much about *what* silverlight is, or what they'd be missing (i.e., interactive, rich content) if they don't install it.  to me, the default badge doesn't pass the mother-in-law factor test.  i first wrote...

in addition to the silverlight devcamps in san francisco and chicago that i mentioned before, my friends from overseas let me know of some other silverlight madness happening. martha rotter is going to be attending the "Silverlight sparks ignite RIA" conference in dublin on 27 SEP.  yes, dublin, ireland, not dublin, ohio, usa.  apparently this is going to happen at a large cineplex as well (i've never been to dublin, but would like to!) so it is silverlight on the silver screen! you can find out details by going to the event information site here. tags: silverlight , silverlightdevcamp , silverlightdevcampsf , silverlightdevcampchicago...

UPDATE: okay, so i dug a little deeper, it looks like these are implementing on a windows form host, so your mileage may vary.  getting interaction with other silverlight DOM/canvas objects might be tricky... well, i have to admit that i only spent about the last 2 minutes looking at these, so this might be an irresponsible post :-), but what i saw was impressive. netikatech just announced on their site that they are releasing 40 controls for silverlight for free!  the product, called "GOA Winforms" describes itself as an implementation of the standard System.Windows.Form class library for rich internet...
