View 1 RepliesIf I'm streaming live video and chatting in an FMS app, should each component have its own instance of NetConnection or should they share one? Was thinking perhaps the quality of the live video stream would be hurt in a sharing situation but am not sure the architecture works like that.
From a development standpoint, I'd like to make one NetConnection instance in my main application file and connect with it. Then, when successfully connected, I'd like to pass that connection into any custom components that need it.
I'm new to flex. Now I'm writing an flex application. I plan to split my application into some MXML files(Application as the root tag). How can I switch from one mxml to another?BTW, what is the best practice for design large flex application? Just one MXML Application and many MXML component or many MXML Application?

eg. of mxml componet may be as simple as button label or text as complex as repeater whose data provider is a web service ( means a fresh quesy should be made to pull the data and refresh the dataprovider of repeater )

Is it possible to move a flex mxml project into flash?
i have the project complete in mxml with actionscript but due to the fact that flex is limited in its visual animations ( no timeline! ) i would prefer to switch to using flash.
they both seem to accomplish the same things with different syntax, whats the point of using two different technologies. highlight every possible benefit of using mxml. Also are there scenarios when one is more beneficial than the other and why. clarify this runtime behavior of mxml vs AS3 as discussed in Oreilly Flex 4 Cookbook page 1:

In mxml application made in flex if i place a part of actionscript code in separate file and include it in mail application using (fx:Script source) , then do i have to import all the mx and spark components in .as included file even though they are were already imported in main mxml application ? For example if i have mx alert already imported in main mxml file then will i have to import in again in the .as file placed externally although .as file is included in main mxml application ?
View 1 RepliesI have Flex application requiring to filter users depending on there database groups.Depending on which group they are, the're is a config.xml file that is use to populate the swf.Here is how I figure how to do this : 1. The client comes to a .aspx page with a form requiring a username and a password. 2. On the server side I confirm the user credential . Once the username/password is valid I redirect to the mxml file with the config.xml file in the html headers (post).My problem comes when I need to get the post data from the http request. Let's say I have this code :
<mx:Application initialize="init()">

Canvas.addChild() insists any DisplayObject added implements IUIComponent. But I don't want my core graphics engine dependent on Flex. Is there an obvious/common way around this, to have simple graphical objects like Sprites & Shapes in a Flex application? The individual DisplayObject children I want to add as children represent objects in a game world, like a spaceship or a missile or a horse...
Not sure if Canvas is the most appropriate container, perhaps Group or another class is optimal for a game-engine... example MXML & AS3 code showing a skeleton setup is most welcome. I'm targeting Flex4 & Flash 10, but Flex3/Flash9 solutions are still of interest.
I would like to send variables or parameters from Component to Main (MXML) Application. Like my component is FileUpload.mxml and would like to forward the uploaded file details from FileUpload.mxml to Main.mxml.

to get the reference for the FileUpload component, however, I am unable to get the variables from the FileUpload.mxml file.

I imported an .fxp project into a Flash Builder and then observed there are 5 .mxml files in the src/(default package) directory. Silly question -- how to run each of these five files?
Since I've named the project differently than any of the .mxml files, whenever I try to run something it uses the default (empty) .mxml file named after the project. Deleting that empty mxml file didn't help anything. I also tried to clean the project, but nothing changes (although I see the directories refresh with the same contents). There are no html files in the bin-debug directory.
There must be some simple way to run those .mxml files that I'm missing.
I would like my spark ItemRenderer to be able to render a varying number of graphical objects that depends on the user input. As an example, let's say that I want to render a set of ellipses on a line.I've been using MXML for my most recent batch of ItemRenderers and have loved every minute of it, but I'm not sure how to accomplish the above goal with an MXML IR. In Actionscript I can acquire the list of ellipses locations and draw them programmatically in the updateDisplayList method. Is there an equivalent in MXML?

How many instances of Video, NetStream and NetConnection would be needed for multiple videos?Not sure that's the right question but essentially here's the objective:Currently, I'm working on an interactive product tour, parts of which are to consist of short video clips, each covering a feature. While only one such clip will be playing at any given time, I'd like put them all at the application's fingertips as part of the initial preloading process before launching into it. The idea is to provide a seamless instant-play user experience without hitting the breaks before individual segments.Honestly, I hate pre-caching crap into user's memory, especially when some of that content may be potentially ignored. However, given the target audience, it is reasonable to predict that all features will be explored most of the time, so it's a fair compromise to me. Besides, I went to great lengths to keep the mp4s' sizes to the minimum.Anyway, I'm guessing you don't really need more than one instance of the Video class but how many NetStreams and NetConnections do I you need, probably one of each per video, ha?

I don't know if I can do what I want in flex, so imagine this in ASP: I have an aspx page that loads a Login.ascx control, the control checks if login is correct, and if so the aspx page loads the XXX.ascx control (so there is only one control visible).
I want to do more or less the same in Flex: I have the main application with the code that connects to the database, check the login, and if its correct it loads a new module. I have made everything until the module load, I mean, I have the main application (Login.mxml) associated to a Login.as, and a Module.mxml associated to a Module.as. When the user press the login button (in Login.mxml), a method is fired and checks the login. If it is correct, it shows the new module.
My problem is that it is shown in the same page that the login page, instead of "changing" the page. I have used two ways to do that: ModuleLoader and PopUpManager, and both load the new module in the same page.
QUESTION: How can I load, inside an application, a Flex module in a different page?
