Hi Not sure that this is a valid programming question ... but is it possible to program infa red using vb.net express (iRDA) Got a programming project in my mind, but none of the coding examples work, IrDAClient never gets recognised Cheers ...
Situation: The server calls listen() (but not accept()!). The client sends a SYN to the server. The server gets the SYN, and then sends a SYN/ACK back to the client. However, the client now hangs up / dies, so it never sends an ACK back to the server. The connection is in the SYN_SENT state. Now another client sends a SYN, gets a SYN/AC...
When using a TCP socket, what does shutdown(sock, SHUT_RD); actually do? Does it just make all recv() calls return an error code? If so, which error code? Does it cause any packets to be sent by the underlying TCP connection? What happens to any data that the other side sends at this point - is it kept, and the window size of the con...
I want to store sockets in my database and retrieve them also. But sockets are not serializable so I was unable to do this. How can I store sockets in a database? ...
There doesn't seem to be any method of Socket, or ListenSocket that will allow me to conditionally accept connections. When I recieve a SYN, I want to be able decide if I want this connection depending on the source, if I send a SYN/ACK back (accept connection) or a RST (a forceful reject). Is there any want to achieve this? Unfortunat...
I'm trying to write a simple server-client program, but I have a problem: I can send data from client to server, but I can't send data from the server (I can't recive it in the client) :( So how to send data from the server, and recive it in the client? Server: //this is in a thread try { server = new ServerSocket(1365); } catch (I...
Hello dear Stackoverflow community! Let's get straight to my question: I have a socket and all input coming via this socket / stream is parsed by my SAX parser. Now, upon a certain parsing event I'd like to close the socket / stream from within my SAX event handler. Also, I want to close the stream from outside in a certain case while t...
Hello, I am trying to make a simple game that goes across a TCP network. The server does something like this to check for connections, in Server.java: try { server = new ServerSocket(port); System.out.println("Server started on port " + port); while (true) { socket = server.accept(); System.out.println(...
Test-cases: Before connection starts it should return false Connection is closed by other end return false Connection is closed by the client return false Connection exists even if no data is avaliable return true class MyConnection { //Assume I have all initialization for _socket public bool IsConnected() { retu...
I got multiple processes listening on the same port subscribed to a multicast address. Packets to this address reach every process. However, when I contact them via unicast, only the newest process gets the message. Where is this behavior documented? How can I change it? Demo program (Python): import socket,os,struct,sys def server():...
I have built a web proxy from scratch (using Socket and NetworkStream classes). I am now trying to implement SSL support for it so that it can handle HTTPS requests and responses. I have a good idea of what I need to do (using SslStream) but I don't know how to determine if the request I get from the client is SSL or not. I have search...
I just had to re-install mysql and I am having a problem starting it up. It cannot find the socket (mysql.sock). The problem is that neither can I. In my Mac OS X 10.4 terminal, I type: "locate mysql.sock", and I get back "/private/tmp/mysql.sock". It makes sense that the socket file exist in that location, but it actually does not. ...
Hello. I am trying to use some socket network programming in C++. I am trying to send the text "Hello World!" to a server using the C++ send() function. At first, I set the buffer to the size of 13 since "Hello World!" altogether is 12 characters (you have to make it one more than the character count). The send function only sends the ch...
I am trying to set up two programs in C#. Basically, a simple client server set up where I want the server to listen for an image from the client. Then, upon receiving the image, will display it in a PictureBox. I keep running into the following error: A first chance exception of type 'System.ArgumentException' occurred in Sys...
Do you guys know fine tutorials, sample codes for SSL socket programming with Jetty? I am going to implement some secured applications with Jetty.. :) ...
I want to do socket programming in C. Where client and server are exchanging messages. I have the sample codes with me, but i wanted some elaborate links and tutorials for socket programming C, so that i can write effective and error free code. I will be working with WinSock library and not on Linux. Any help? ...
I have a server than is a "command handler" process. It receives messages over UDP, and delegates the work to do to a different process by communicating to that process through it's published API (whatever IPC mechanism that process employes). Our system has several cooperating processes. The result of that API call is then then sent ...
I have a socket app that passes data between 2 processes. It works fine on a number of computers with the 2 processes running on the same computer. A person in my office visited a government office where they made some unknown changes to her laptop so she could get on their network. When she left the app no longer works. If she tri...
If you have the following class as a network packet payload: class Payload { char field0; int field1; char field2; int field3; }; Does using a class like Payload leave the recipient of the data susceptible to alignment issues when receiving the data over a socket? I would think that the class would either need to be reo...
When doing socket programming, people always name the addrinfo struct like this: struct addrinfo hints; // get ready to connect status = getaddrinfo("www.example.net", "3490", &hints, &servinfo); I'd like to know what it stands for for better understanding. Thanks in advance. Thanks for the answers. Maybe I didn't make me clear. ...
