Hi All, I keep getting the following error when debugging. Cross-thread operation not valid: Control 'richTextBoxReceivedMsg' accessed from a thread other than the thread it was created on. Here's the code that it points to: public void OnDataReceived(IAsyncResult asyn) { try { SocketPacket socket...
I'm discussing Silverlight (v4 onwards) as a possible platform for a program that will need two instances to communicate directly. As far as I can tell, this is still not possible with the SL sockets assumptions of client-server comms. Assume it is for a highly interactive two-player game and you will have a good idea of the performance...

My webhost has rules against socket servers so I've been looking into GAE. Does anyone know of a socket server that can successfully run on GAE? I'm using it for flash so anything like smartfox would be amazing if it's possible. Thanks. ...
Some web servers return content-length set to zero in the HTTP response headers. I'd like a deterministic and performant solution for receiving all the data in that situation. URL known to exhibit this behavior (additional URLs below): http://www.washingtonpost.com/wp-dyn/content/article/2010/02/12/AR2010021204894.html?hpid=topnews he...
I have a C++ Program listening for incoming socket connections on port 2222. I have an Adobe AIR/Flex application that attempts to connect to it, when I click a button. When I Connect To My Socket Over My Intranet, My C++ program hears and accepts the incoming socket connection and Everything Works Fine: var Sock:Socket=new Socket("192...
I'd like to establish a server(Java)/client (Matlab) communication using socket. They can send messages to each other. An example shows how to do this in Java server and Java client, http://java.sun.com/docs/books/tutorial/networking/sockets/clientServer.html. When I try to rewrite the client part in Matlab, I only can get the first me...

Hey all, I am trying to determine the status of some servers over the course of time. Here is my code: static void Main(string[] args) { byte[] readstream = new byte[100]; byte[] sendstream = Encoding.ASCII.GetBytes("PLAYER_JOINED"); string[] IPs = new string[] { "24.15.169.211", "69.198.255.121", "219.79.24...
I've got an interesting issue with my socket test application. I've set up a listening socket with an AcceptCallback function. I've connected to the listening socket using : CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault, (CFStringRef) self.clientService.hostName, ...

Hi guys, I have a server socket (on port 3490) in my app which has a video data - It runs on a different thread. Now I have a mpmovieplayercontroller and would like to read the data from the socket and play it. I'm not sure what url should I pass to it. I've tried file://localhost:3490 http://localhost:3490 but this doesn't work. Pleas...
Hi guys My program consists of 2 parts - A server socket running on a different thread, and a client to test the server. I'm 99.9% sure that the server is correctly written (because I have tested it with a client socket), and all it does is returns "hello world" as a response. The server sits on port 3490. Now what I tried to do is t...
I'm developing a server application that asynchronously accepts TCP connections (BeginAccept/EndAccept) and data (BeginReceive/EndReceive). The protocol requires an ACK to be sent whenever the EOM character is found before it will send the next message. The accept and receive are working but the sending app is not receiving the ACK (sent...
If my program crashes before a socket is closed, the next time I run in, I get an error that looks like this; socket.error: [Errno 48] Address already in use Changing the port fixes the problem. Is there any way to avoid this, and why does this happen (when the program exits, shouldn't the socket be garbage collected, and closed)? ...
Hi, I have connected my Android application to a Windows desktop machine via Bluetooth. The application interacts with the machine. At the end of the interaction the application on the desktop closes the socket that was opened between the Android and the desktop application.
