In a RIA application you are supposed to put as much business logic as possible outside of the RIA layers (flash/silverlight etc). What is the reason behind this? Any logic that goes into the presentation tier gets the benefit of executing faster...
Is this because the RIA technology will most likely need a face lift down the road and you will have to rewrite all the business logic?
As it is said here: [URL] "If you do a Google search today for "MVVM and Flex", the first post is by somebody who claims that MVVM is not a good fit for Flex. I couldn't disagree more. Out of the box, the Flex framework makes it much easier to implement a Presentation Model than similar MVVM implementations in Silverlight. That is not to say that there aren't good third-party libraries that make it easier in Silverlight, but without any help, it is easier to do in Flex." So MVVM as LOGICAL CONCEPT can be implemented in both but the way it is implemented in Silverlight requires more Plumbing than Flex.
What prevents Silverlight MVVM to be implemented like Flex ? Doesn't Silverlight have same capability in event system to do the same? If yes why does Silverlight do things more complicated what's the advantages then ? Is it about using Class Interfaces which are more strongly typed? What are the disadvantages also ? For example as for implementing MULTIPLE VIEWS for 1 View-Model does Flex implementation make it also more obvious?
I have to decide whether I should choose a Flash or a HTML5 presentation tier third party application for displaying virtual tours. The thing is: The Flash app is better, but doesn't work one iPad. Which do you think I should go for? Flash, high quality or HTML5, a little worst quality?
View 3 RepliesI'm currently using RobotLegs with the Presentation Model pattern to develop a Flex 4 project. I understand that all business logic related to a View resides in the Presentation Model associated with that view, however, I am confused when it comes to View specific logic.For example, I have an indicator that needs to be positioned relatively to list items depending on which list item is selected. Is it acceptable in the Presentation pattern to put the logic that will position the indicator in the View and simply have that logic run in reaction to a selectedIndex property changing in the presentation model?The reason I am considering this is that since the Presentation Model does not have a reference to the view it is difficult to come up with an ideal solution for manipulating view components.

View 1 Repliesi need a webpage (host on my website) that can play the following mp4 file either via silverlight 4 or flash[URL]..i tried various solution like flowplayer and silverlight but none of them work with the URL above. I can play the file fine using Windows media player or VLC.
For silverlight, i always get AG_E_NETWORK_ERROR exception within MediaFailed event. For flash, via flowplayer, IE page is just blank
Can someone tell me what am i missing? i am very frustrated as I have finished encoding, upload, cataloging my videos and now I am stuck at the last step.
I found Vectorlight which is quite good, but are there any tutorials or books about doing cool effects with silverlight. I'm after for resources focused more for a designing and presentation. Mostly the books about Silverlight is focused on doing boring business applications like making grids and forms.

View 1 RepliesI'm trying to make a guitar practice website, and a critical functionality is to loop over very short mp3 files (a few seconds long), with absolutely zero gap in between. For example, it could a 4-measures-long chord progression, and I want to allow the user to loop over it seamlessly.
I tried using the HTML5 <audio> tag with the loop attribute. Google Chrome gives a small gap between the loops, but big enough to be totally unacceptable for my purpose. I haven't tested the other browsers, but I believe it won't work.A possible workaround is to use ffmpeg to stream repetitions the same audio as an mp3. However, this costs a lot of bandwidth.
For myself I use Audacity to loop without gaps, but unfortunately Audacity doesn't have a web version.So, do you have any ideas how I may loop over an mp3 in a browser with zero gap? I prefer non-Flash solutions, but if nothing else works I'll use Flash.
I'm desperately trying to source a 3-tier drop down navigation menu and am willing to pay for it.

I am about to start a Flex project. For the GUI, I'll follow the Cairngorm 3 guidelines and use (most likely) Parseley. I have experience with Grails, Spring, Seam and also have played with PHP. So, which one of these framework has a better integration with Flex? By "better integration", I mean, in the order of importance, coding-friendly, documentation, maturity, size of community (of the integration framework/library), support.
View 2 RepliesI'm looking for help putting together a some website navigation and wondered if i should be doing it action script or not (i'm assuming it should be).

View 1 RepliesI have to take a number and figure out which "tier" it falls into.For example, let's say I have a table that has three tiers "economy" "typical" "deluxe". From 0-12 is economy, 13-20 is typical, 21-30 is deluxe. My actual table has many more levels, but this is the concept.
What's the fastest and easiest way to do that? I was going to use a switch statement starting with the highest, but it doesn't look like that can be done
how would the 3-tier architecture be applied in a Rich Internet Application?I thougt that flex was presentation, .net web services where busines and informix was data. But then when I started I feel that I must be wrong.
View 1 RepliesWould like to understand the basic process behind an ecard before I attempt to construct one!Obviously there could be the following elements:Initial web page containing a Swf (choose swf) offering a user a choise of ecards and a consisting of a series of text input fields to collect recipients and senders address and a message. With actionscript that calls a php file on the server.
Passing variables holding the card choise the card text the email from and to etc from swf to php file.The php script runs and creates a copy of a swf card, the one chosen by the user(swf1) It populates the swf copy with text from the variables set by the choose card swf.the php then sends an email to the recipient address with ? and this is where I am unclear?Does it send an attachment of the swf1 or how does it do it?

I was given a task to make a match making game in actionscript 2, problem is, i have very little knowledge about the language (well, and how matching works in as2, what are the important codes, code emplacements, and all I am new in AS2, and i really need a lot of help with our project. :)
I plan to match images. But.. I was planning to have a sort of "Compatibility" match-up game, like,..let's say we have two batteries, one has a 50v capacity(how do u measure batteries?) then the other has a 100v capacity, then there's this battery slot that only accepts a 50v battery, then you will have to match this 50v battery to that battery slot, that's my concept for the game, sir. I hope you got what i said, sir. :D

View 2 RepliesI'm working on an app which will, like most apps, have a whole boat load of buisness logic, almost all of which will need to be executed both on the server and the Flash-based client And I'm trying to figure out the best (read: least complex) way to implement the rules engine.
These are the parameters of the problem:
The rules engine must both run in a web browser (ie, in Flash Player) and on the server. Duplicating the logic (eg, by writing a "server" version and a "client" version) would be an unacceptable risk. The input/output data is fairly complex, so serialization is a nontrivial problem. We are currently using AMF for all of our serialization needs, and using another protocol would add significant complexity So it should probably be avoided. It is infeasible to implement a "rules description language". Experimentation has shown that rules are sufficiently complex that any such language would need to be Turing complete Which would also add a significant amount of complexity. The rules engine will not need to make some, but not very many, service calls.
Currently, the best contenders are:
Writing the code in ActionScript, then running it on the server. In theory it's possible to start up an AVM instance, get it long-polling a gateway, then pass data back and forth that way But that seems less than ideal. Writing the code in haXe. I don't know anything about haXe's AMF support, so that could be a deal-breaker. Something involving Tamarin. Seems like a viable option, but I haven't done enough research to tell either way.
