C++ :: Transmit Data From C++ To Flex / Air Faster Than Sockets?
Feb 1, 2012
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 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.

Sometimes flash-socket ignors data which is being sent by server. I dunna know exactly if it's server-side problem(data actually aint being sent) or flash.How does flash handle numerous of data packages comming from server ? I know that flash perform all actions in single thread, but what happen when flash recive a lot of packages at same time ? Does flash serialize incomming packages and then call ProgressEvent.SOCKET_DATA for each package or just ignore those packages which cant be handled runtime ?

I am attempting to connect to a python twisted socket server with Flash using XMLSocket. The connect works fine, and so does the receive. However I can't send data to the server. Is there a specific format I should be using? The reason I ask is because I couldn't read any data with the XMLSocket until the data was in the form "something", that is, the data string had to be valid xml followed by the null character. Is there a trick to sending data?
I don't think this a cross site security problem, because if it was, I believe I wouldn't be able to connect or receive. I am able to connect to the server using telnet and a java client without issues. EDIT: I figured it out, the problem was my server needed to have the data sent to it end with"

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.

My question is, does a better, faster CPU necessarily equal faster SWF compile times? Or does it rely on something else (OS, memory, etc). I only use AS3 and some of my projects take a while to compile. If certain hardware can guarantee me a faster compile time, it'd be worth including those things in my shopping list.

I have a pretty elaborate class that extends Socket and performs some serialization and data protocol stuff. It works pretty well when I send small messages. However, when I send anything over about 132KB at once, the SOCKET_DATA progress events stop firing -- or at least the function I've got listening for them does. My class is called RPCSocket and I assign the socketDataHandler function like this in my constructor:
addEventListener(ProgressEvent.SOCKET_DATA, socketDataHandler);
My socketDataHandler function (with lots of comments) is attached. Is there some limit to how much data can be sent over a socket at once? Is there something wrong with my code? Here's the trace output:
Code:
socketdatahandler
bytesAvail:4380
buffer length:0
reading bytes into buffer for concat
buffer length after concat:4380

it seems that Flash was supposed to run in a sandbox in the browser. But, if Flash can get data from a remote server, can it similarly get data from localhost IP on the same machine? In other words, can I use a Windows app that provides a TCP socket on localhost to feed data into a Flash app?the answer is yes at least for the case of an SWF file hosted in the file system, URL...(turns out the localhost access error can be fixed if you add the SWF app to some security whitelist). Still wondering if this can also be done for SWF apps hosted on the network.

We're developing an socketserver who should receive xml. our specification said, a xml stream starts with
<?xml version="1.0" encoding="UTF-8"?><logmsg> and end with </logmsg> Now, i try to add the XML-declaration line to my XML-Object, without success. A own written socket monitor shows only the <logmsg></logmsg>-Nodes. Also trace show similiar informations. Is it possible to add the xml-declaration to an XML-Object overall?

There's no access to the HTTP cookies from within a Flash movie, but I now have repeatedly read that Flash Player is supposed to take care of session cookies automatically. I could, however, not find any documentation about this, and it sure didn't work with my Flex client running against a Struts backend using the default JSESSIONID cookie.

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 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 made a Flex 4 web application. Upon testing locally, I already got satisfied at how it looks like. However, the swf's file size grew to around 6mb in size so when I uploaded it to my website and viewed it, it takes forever to load on a computer with quite slow internet connection. So my question is, how do I make it load faster? Should I:
separate it into chunks? If so how do I do it.
not put the embedded images inside the SWF but instead, store it outside in a folder? If so, how do I make it load on the background while the user is interacting with the primarily loaded parts of the web app?

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 have seen a few blog entries on this and have had a discussion or two with my team mates but I would like to see what the stack overflow community thinks.
So why does the Adobe Alchemy Tool create so much faster running flash byte code than the flex compiler?
Also, when will the flex compiler be able to make similar performance gains? Will it require programmer specific use of special Array's or something of that nature to get the same performance?

I am not any kind of network programming pro, but it happened that I have faced necessity to develop socket-server on php (no way for using Java) for flash multiplayer browser-game (standard features like locations, team battles, etc).
The main problem is that TCP is point-to-point protocol and it completely occupies given port.Of course it is possible to create some kind of queue, which will manage connections to the socket, but this solution doesn't seems to be the fittest one.
It seems to me that using interval of "fair" ports (from 2000 to 2200, for example) is more fitting solution, because one request may take a lot of time to execute and players won't be happy to wait in queue.
But how can I implement this "port inteval" strategy?The solutions that I see are:
launcing php-script per every port (he-he, 2 hundreds of launched scripts!);somehow forking the initial process to new processes (2 hundreds of processed? Not nice too), one for every port;additional while-loop, which listens all the ports (looks very bad);using threading or something like that (the problem is that php is single-threaded, as far as I know; pcntl?).But somehow I don't like any of them, or at least don't know how to implement them in the best possible way.
What is the best existing strategy to handle multiple requests from multiple users per time unit without delays, and how to implement this strategy in php? We have our own Debian-server, so it is possible to use any required php extensions.
For example, if we are trying to develop chat application, we need some sort of fixed (I mean persistent) connections for each user. For example, we have 80 users in chat, and then one of them posted a message, which server tries to handle and send to all other connected users, also putting an entry to the history file or something like that.
In this situation polling server for new messages every 10 seconds from each of 80 users is craziness, so the need in persistent connection gets obvious.But I don't know what is the best way to implement something like this, considering that not all requests are handled instanlty.
