Flex :: Sockets And Looping - Getting The Valid Connection?
Jan 13, 2012
On my network I have a couple of pc's all running a bespoke server which will return the username of the person logged in when queried.I have the following piece of code.
private function LoopAndList():void
{
var loopSocket:Socket;
var fourthOctet:Number = 6;
[code]....
Now when this runs it doesn't work as I first thought. The iterations go though. the fourthOctet value is decremented. But somethinjg strange happens. You will notice in the above code that I have a hardcoded IP address in the loop. I have put this there to ensure that there is always a valid connection. So am aware it will always be connecting to 192.168.0.4.
But the connection only happens on the last connect call.
The ouput is:
192.168.0.6
Connecting to 192.168.0.6
192.168.0.5
Connecting to 192.168.0.5
I want to open a connection back to the server using Flex so I can stream chat messages to the Flex front-end. How do I do this and does Flex enforce any same-origin restrictions on ports or subdomains?
So, we want to move out from Air (Adobe stopping support and really bad implementation for the sqlite api, among other things). I want to make 3 things:
Connect with a flash (not web) application to a local mysql database. Connect with a falsh (not web) application to a remote mysql database. Connect with a flash (web) application with a remote mysql database.
[Code]...
if you can connect with socket wit mysql server, why use a web server (for example with php) to connect like a inter connectioN? why not connnect directly? I have done this a lot of times, using AMFPHP for example, but wouldn't be faster going directly? In the case of accessing local machine, it will be a more simple deploy application that only require the flash application + mysql server, not need to also instal a web server.
I read about a project that enables the developer to program a HTML5 web sockets application that is compatible with older browsers by automatically falling back to using a flash method.
I've written a basic FTP client to allow me to upload files through the browser without using the FileReference.upload() func (because it's damn slow). I've got all the socket logic worked out and it works for one upload. When the upload is completed, the FTP data socket is closed by the socket.close() func which triggers a response from the command socket and starts the whole process over again. This logic works perfectly on my Mac in both Safari and FF.
I can upload files and cancel uploads and it all works as I want. When I test it on Windows (IE 8, FF 3.5, Safari 4 on WinXP and Win7) it is busted. I've tracked down the problem to the fact that on Windows, the socket.close() function is not causing the server to close the connection. I don't know if this is because it's not sending a proper command or what... but that's where it's at.
This is driving me nuts and because it's a combination of various technologies together I have a hard time tracking the problem. I wrote a tiny HTTP server that serves .flv files; these flv files are encoded on the spot. The flv files are encoded with adobe's screencodec (I started with libflv but that was too buggy so I ended up implementing my own flv encoder). For the problem below it doesn't matter which codec I use or if I serve plain flv files instead of on-the-spot generated ones (the problem also occurs if I just send 12 h264 encoded files).
I also have a swf that I coded in as3. The as3 opens 12 connections to my server and requests 12 different flv's and just displays them as 12 different videos on the page. I tested the setup with Firefox and chrome and am using the latest flash client (version 10). The HTTP server is pseudo streaming those files; e.g. it tells the client the file is of mime type video/x-flv, tells the filesize is 2GB and just starts streaming. For sake of completeness here's a header it generates:
Most JavaScript code is also syntactically valid ActionScript 3.0 code. However, there are some exceptions which leads me to my question:
Which constructs/features in JavaScript are syntactically invalid in ActionScript 3.0? Please provide concrete examples of JavaScript code (basic JavaScript code without DOM API usage) that is NOT valid ActionScript 3.0 code.
Im trying to make connection from flex to java and from java to mysql. I managed to connect to java, but having error that class not found: com.mysql.jdbc.Driver. But i downloaded mysql.jar, included it added to library, and connection works when i testing it from clipse scrapbook. Dont know what to do, i spend last couple days on this.
Basically the solution was simple. Everybody keeps saying to put jar into lib folder, so i done it, but i wasnt realised that i have to put into my servers lib directory, not app lib directory and this miserable mistake cost so much. Anyway i hope this will help for some newbie like me.In this particular situation im using red5, so i putted it into my red5 dist/lib directory and "surprisingly" its started to work.
i want to check in Adobe AIR if given regex is valid. I'm looking for somtehing similar like here: How to check if a given Regex is valid?
I dont want to compare regex and text-value - i jus want to check if this regex is valid. If someone type invalid regex - for example: "x{5,-3}" or "(((^^$$$)//)" or something like this i just need to communicate to him that this regular expression is not valid - its not proper regular expression.
I am having a problem with my build. When I add a valid statement to the code it will no longer complie and it fails with errors from an unrelated file.I experience these issues building with ant or building with mxmlc on the command line.Adding a valid statement to an myLittleBox.mxml will cause this error.All the errors are in ViewerMain.mxml.This file is not the main mxml file but it is referenced from the main mxml file.Before changing myLittleBox.mxml ViewerMain.mxml had no compile errors.There are no errors related to myLittleBox.mxml myLittleBox. mxml has no references to ViewerMain and only uses spark components ViewerMain.mxml has no direct references to myLittleBox.mxml. Its children's children's children would have a reference to myLittleBox.mxml.The valid statement added to myLittleBox.mxml could be many things (they all break it) including a comment.[code]
I noticed that the Model was using a constant in Viewer 1.This was causing all of Viewer 1 to be built when Viewer 2 is built.I moved the constant from Viewer 1 to the the Model (where it really should have been anyways) and my project built successfully since Viewer 1 and Viewer 2 were not being built at the same time.It makes sense that this would resolve the issue however this is just resolving a symptom of the issue.I am still very curious what was causing the the compiler to fail on ViewerMain.mxml when I add a comment to myLittleBox.mxml.I guess that it will remain a mystery for now.
I am trying to do a "hello world" level test of FTP in Flex, but for three days now, I cannot overcome the issue with how to coerce flex into accepting my crossdomain policy - even for testing purposes.Here is my code: The exact error text follows.
i am working with actionscript flex and using UIcomponents i need all the valid arguments for this function for example component.setStyle("borderColor","white");
i need all valid strings for first string parameter and 2nd valid argument for there value setting,
i have some of them that are given below but i need all possible values for this function

Its showing me connecting ... Status is not getting update like: "Connection Failed" or "Connection Success". how to use the above information in this app,
I am building a really simple Chat server/client using PHP and Flex. I have followed many tutorials and have a working server in PHP and a working client in Flex, except that if I use the client on Windows I can't send any messages.When I send a message on my Mac it goes through to the server and gets sent to all the clients, including any Windows client I may have connected. The message will actually display on Windows clients as well, it's only when I try sending from Windows that it doesn't work.
I've tried adding a crossdomain.xml file served by a PHP script listening on the correct port, but none of the clients ever seem to ask for it, and if the client works on Mac I assumed it should work on Windows. By the way I'm exporting the project as an AIR file (dunno if that makes a difference).I can't find anything regarding this so I'm wondering if I'm being stupid somewhere or whether I need to takes some special measures for Windows clients?I have pasted my client code below.
I have a C++ application which sends images to a Flex/Air front-end via TCP sockets. All this data transfer occur in the same host, so the socket connects to a localhost server. The problem is that the Flex/Air takes a really long time to read the entire image from the socket. The server sends the image quite fast, but the Flex/Air reads this image in tiny parts. The whole image has about 300MB and the Flex/AIR reads only about 1KB each iteration. So the flex keeps calling the socket data callback, which is causing the application to slowdown.
Is there any synchronous sockets to use with flex, or some kind of socket which can read the entire data all at once? If sockets aren't the best choice, is there any other faster options? My socket class looks like this:
I've been searching extensively for a way of converting from ordanance survey coords to valid esri coordinates. I've found quite a few pages that convert to lat long (if a little off) but nothing to convert to esri (which I believe is utm.)This is for use in python or JavaScript / actionscript etc - I'm not too worried about syntax more an understanding of the maths involved.
I am building a Rails app that would nicely communicate with Flex via sockets. Currently I found only two ways of communication: Simple HttpRequest, RemoteObject. But I need something "multiplayer" style. I need Flex to talk to sockets and Rails app to grab data from those sockets do some job and push something back to a socket so Flex could read it "on the fly".
I'm building a multiplayer card game using Flex on the client side and Java on the server side and I wanted to know if I must sockets and the accept method in order to connect users to the server for in order for them to join a game room or create one or to chat.In the past I've learned how to build a game server which both sides are JAVA and connection was in sockets but now days the client side will be in FLEX which has few ways to connect to a Java server (XML,SOAP,BLAZEDS(AMF)) and I find it hard to understand how to write the Java server in order to do all the features of a game server,especially managing the rooms and sending data back to the users.
In the sockets way, when a user was connecting to the server and he had opened a room, this room was opened on a thread and who ever was joined that room then he was connected to the same thread and sending the messages to the right place was easy, so the problem is understanding how to do the same using SOAP or BLAZEDS.
I've started with Flex recently, I've noticed that some plugin for Visual Studio exist, instead of buying a licence for another program (Flex Builder).I was wondering how I could manage to remotely connect to my database with a Flash/Flex application with the help of C#/Asp.Net.
If I've correctly understood what I've read in the last few days, there is basically no way to 'query' to a database with Flex 3. So I suppose there is another way by using a webservice in C# on the database server that would respond to the Http query from Flex.
Is there a timeout on the connection made by URLLoader.load? If there is, what's its value, where is it documented and can it be changed? Also, what event (if any) gets dispatched if the timeout occurs? Is there a difference between AIR and browser application in those regard?
I am working on a project using flex/java/blazeds. This worked fine on local host however now that i have uploaded to a tomcat server(online), after having an error with the service uri, this error has now seemingly been solved, yet I am receiving another error which is as follows:
I am creating an air app that uses HTTPService to connect to a .net api and get a user for example. It works great when I publish the move for "Flash Player 10" as a .swf, however, when I publish it as .air it seems like there is no internet connection at all. I am assuming it's internet securities (maybe firewall). I turned off my firewall and everything that might be blocking the internet access, but nothing seems to work.
I installed red5 successfully, but when I try to connect to red5 to stream a video, the connection fails. If I use netstreaming(null), it works, but when I use red5, it doesn't.
i was to create a type of ftp connection using flash/flex, however because actionscript doesnt support ftp i need to use other programs such as c#.net.intergration i have seen can be done with tools like WebOrb for .Net however because this is an Air application i want to be able to access .net class files(dll) from flash without havent to be connected to any sort of server.however i cant find any solutions to connecting to .net classes as a standalone application.
