Flex :: Server Client Communication - Display Emergency Alert Message
Oct 1, 2010
I have 12 display monitors installed in different floors in a building. These monitors display announcements that will be update once in a day. I'm retrieving these announcements from db and storing in an array and displaying it all day long. In addition to this, I have a requirement to display emergency alert messages on the monitors. My Server is a windows 2000 server. I'm using asp for creating the JSON object.
For the emergency alert I am thinking of doing this:
Create a page in asp that lets user to enter emergency msg and save to db.
Create a page in asp that will check if there an emergency msg in db and show it in a asp page in json.
Create a timer that pings this json page every 1 second. If it's available then show it.
Is there any other sophisticated method available to poll the server or to send messages from server to client?

I am fairly new to FMS and really am trying to learn about it. My question is simple I hope;
I would like a message to pop up to a client when they connect that the max users has been reached. I have it set for 5 users and so I would like when the 6th user tries to connect to watch the video, a little box will pop up and say "Sorry, Max users has been reached. Please try again in a few minutes."
I was able to develop something and get it output through trace commands by following a tutorial I saw online, but I could never get any sort of message box I built to pop up.

We're currently working on a small scale indie card game for Facebook, which we hope will reach hundreds of thousands of players (eventually). We have most of the issues figured out (scalability, server-side architecture, etc) - however one question - communication between client & server.
We have the following requirements:
Server side push messages (no client message request) High scalability (should support at first hundreds and later hopefully thousands of CCUs) Secure, reliable layer Work well with most computers, routers & browsers Works with Adobe Flash/AS3
First thing that came to mind was socket connections, but I was wondering, is there a better solution that answers our needs?

I'm working on a project for a User Interface Design class, so the emphasis is on the UI being as nice to use and non-annoying as possible. I would like to display a message to the user after they've clicked save, for example, without requiring them to click an OK button. I'm thinking of the kind of thing you see in gmail if you send a message or do some other actions, where a message appears on the screen, but the message disappears after you do something else.
I'm sure there's a way to do this in Flex (I'm using 4.6), but I just don't know what it is. I'm pretty new to Flex and I'm having trouble finding anything via Google, because the results keep showing confirmations messages in Alerts; I don't know the search terms to get the results I'm looking for.

I have a colleague who will be using Adobe Flex and adobe flash builder to design the application. The final application will be in that software. I am creating the database features and testing them using online browsers.What I want to know is that some alerts I am getting a 'prevent this message from multiple dialogues' message on the alert but this is because of the browsers. But if the application is on flex and flash builder (I don't know which one is where the app is stored coz I have never used it) then will that message appear on some alerts in that software or is it only on browsers?[code]

I am using BlazeDS for data-push feature in my Flex application project. From the official tutorial, Getting started with BlazeDS, it shows messaging example with producer/consumer from API. but how can I implement server side which doesn't need to be invoke from Flex client, but from within server-side instead. I got some idea but I don't know how to do because I'm a Flex developer, not Java developer In Google, there's a tutorial show about I need to extend ServiceAdapter class in Java-side, which extends Invoke method. Do I need to extend other class instead of this to do what I want?

I have a timer in my application. For every 30 min, it will hit the web services and fetch the data and updates the UI. The application was working fine till yesterday. Suddenly, because of some issue, the web services were not available for some time. During that period, Application displayed the RPC Error multiple times(More than 100 alert boxes) in alert window. Because of this alert boxes, my application was hanged and i was not able to do anything.
I have tried several approaches, but nothing worked.Finally, I have tried to use a flag. In all the approaches, this looked promising. so i have implemented it.Basically, in this approach whenever we open an alert we will set a flag.While opening and closing alert we will reset this flag.

We're writing a flash application that can download a MP3 file, convert it to a Sound object, get the raw data and make some processing (like adding sounds, change octaves). After the processing, we want to send the data back to the server in chunks, so the server will be able to glue the data together and recover the new generated file. The problem is: if we send to the server "wav" pieces of sound, we are able to glue them together without any problem in the generated file. However, if we convert each wav piece to a mp3 file (so we can send a smaller file to the server) and join the mp3 files at the server, the result is a sound with some problems at the merge point.
This is how we load the mp3 file from the server:
sourceSnd.load(new URLRequest("sample url to mp3"));
sourceSnd.addEventListener(Event.COMPLETE, carregou);
This is how we convert each piece of mp3 to bytearray and wav:

I thought that it was the NetStream.Play.UnpublishNotify in the NetStatusEvent but that doesn't get fired when I stop the live stream. The onFCUnsubscribe event does get fired, however, I have a 5 second buffer and it doesn't wait for that buffer. It gets that event almost instantly. What is the correct way to alert a user that the stream is finished?

I am having an issue where I show an AlertBox message when the user hits ENTER and the focus is in a text area. The pop up works fine, but when the user hits enter the Alert closes as expected, but the TextArea listener receives the ENTER event from the Alert and pops the dialog up again. I have tried a number of ways to catch and eat the event but so far I have not been lucky. Is there way to accomplish this?

how in Flex can I display a message within a Spark List component that states that the List is empty. For example if I have a List showing number of jobs outstanding, if my List is empty then I want a message displayed across the List stating "there are no jobs to perform".
I'd rather not use an Item Renderer because then it's an Item (the list is not empty) and the item can be selected.

I've read some books on creating stateless websites, I've read some about stateful client applications, but a lot of complexity comes along when you have to combine both. We have a Flex application that needs to persist data to a database via .NET services. Things to keep in mind are:
- Concurrency (optimistic/pessimistic)
- Performance: Flex needs to load in lots of data so lazy-loading is often necessary.
- Do you use Dto's to transfer data between server and client?
I'll tell you the history of our product. We've used SubSonic from the beginning as a o/r mapper. SubSonic objects are converted to dto's written by us and these dto's are transferred to the client. Clientside the dto's are converted to the domain model. If clientside a domain model object needs to be saved, it is converted back to a dto and send to the server. Server side the dto is converted to a subsonic object and saved to the database.
Now, some time ago, we needed the domain model on the .NET server side... so now we have like three models on the server side, the subsonic model, the dto model and the domain model. The dto model is more simple and resembles the database more, the domain model has much more logic. It gets complex... We now have to synchronize the AS3 domain model code with the C# domain model code. If we could do it again (of get time to refactor) I think we wouldn't use the dto's anymore, but transfer the domain model between client and server. Dto's are simple objects so easy to transfer. Domain model objects can be very complex.

I'm building a Flex application, which is going to perform many server requests (let's say, that almost all interactions require an update from server). At the moment I'm using remote procedure calls for it. But I was wondering if using a socket would be better. In other terms, is maybe better to keep the connection alive rather then performing many calls in sequence? For my demo app I only have 1 client. Is the number of clients connecting to the server a factor for this choice?

I have created a client with Flex Builder which works in a browser but also in an Air windowed application. I must connect it to a server and it has to do asynchronous request related to changing data of the server.Because of the too much expensive cost of LiveCycleDS license, I was looking for other ways, maybe open source and i found the following solutions:
Adobe BlazeDS
Granite Data Services
WebORB Community Edition
I want to ask you which is the easy way to create the solution described above, expecially i want to use J2EE application server type.

As far as In understand the Flex technology, a Flex client connects to a Flex server to retrieve business information. Is this the only allowed connection for the client, back to the originating server? Or can a Flex client also open a secondary connection to a different server wich runs BlazeDS for message exchange?(This might offer an option for load balancing and cross-platform development).
Update: I have found this page which links to the Cross-domain policy file specification:[URL]..

But what I want to do is to read the file from client and parse it without uploading it to the server.

I'm a new grad, so please be kind. I'm working on validating input in a Flex DataGrid cell that the user can edit. The rows in the DataGrid are backed by an mx.collections.ArrayCollection that includes a [Bindable]Model that I wrote. I want to validate against a custom client-side Validator, if-and-only-if that passes I want to validate the input on the server. If client-side validation fails, I want to display the normal validation error (see image below). If server-side validation fails, I want to use the same sort of UI components to notify the user. The solution should not include any external framework (Cairngorm or PureMVC).
[Code]...
How do Flex programmers validate on the server, immediately after the valid client-side validation passes?
I realize it seems silly to search out this "synchronous" design and I hope someone has an answer to solve my problem with best practices. In my defense, the reason I want to validate on the server immediately following client-side validation is so that I'm using Flex's validation framework. If I get an invalid response from the server, I want to leverage the built-in UI components that Flex has to tell the user something is incorrect about his/her input.

I have Flex/AIR app that connects to a tomcat server via BlazeDS. I'm not finding that I have to integrate an old webapp (struts/jsp) and I'd like to keep that webapp untouched except for login, authentication and session handling. Also a 3rd java app that uses httpclient.
Currently I have some blazeDS remote objects to handle login/logout with a few RPC calls. In turn, FlexSession objects are created and handled. Is there a way to use httpclient and javascript to call those blazeds RPCs so I dont have to recode and have 3 different means to handle logins and sessions?
