tcpclient

Effectively I'm trying to send some template emails so that I can test a few components that handle reading from mailboxes. I could just load up outlook and send a couple of emails but I'm looking to find a solution that can read thousands of emails at a time so I need to bulk send these templates t test the reading code. When I say bulk send ... I have about 10 to 15 templates (varies) and I want to send about 1,000 copies of each to the given mailbox. Now here's th sticking point ... I could just fire up an instance of the SMTP client and declare a new MailMessage object then send that using

I'm trying to send a GET request to a page via TCP stream. Here's what my code looks like: public class SocketLevelWebClient { public string SendWebRequest(string url, string request) { using(TcpClient tc = new TcpClient()) { tc.Connect(url, 80); using (NetworkStream ns = tc.GetStream()) { using (System.IO.StreamWriter sw = new System.IO.StreamWriter(ns)) { using (System.IO.StreamReader sr = new System.IO.StreamReader(ns)) { sw.Write(request); sw.Flush(); return sr.ReadToEnd(); } } } } } And the request itself: SocketLevelWebClient wc = new SocketLevelWebClient(); var r=wc.SendWebRequest("www

I am working on a project and have a question about Java sockets. The source file which can be found here . After successfully transmitting the file size in plain text I need to transfer binary data. (DVD .Vob files) I have a loop such as // Read this files size long fileSize = Integer.parseInt(in.readLine()); // Read the block size they are going to use int blockSize = Integer.parseInt(in.readLine()); byte[] buffer = new byte[blockSize]; // Bytes "red" long bytesRead = 0; int read = 0; while(bytesRead < fileSize){ System.out.println("received " + bytesRead + " bytes" + " of " + fileSize + "

I'm wondering how to stop Networkstream.Read() from blocking thread. I have separate thread where NetworkStream.Read() is waiting for data from server. Assume that user press some button that send some data to server. But I can't call NetworkStream.Write() while there is NetworkStream.Read() in other thread waiting for data. I can lock NetworkStream each time but NetworkStream.Read() will block thread so I can't send data until read at least 1 byte. Bjorn Coltof You can issue both read and write simultaneously as stated in the docs at MSDN docs Read and write operations can be performed

What would the proper way to cancel TcpClient ReadAsync operation by timeout and catch this timeout event in .NET 4.5? TcpClient.ReadTimeout seems to be applied to the sync Read only. UPDATE: Tried tro apply the approach desribed here Cancelling an Asynchronous Operation var buffer = new byte[4096]; CancellationTokenSource cts = new CancellationTokenSource(5000); int amountRead = await tcpClientStream.ReadAsync(buffer, 0, 4096, cts.Token); but it never cancels by timeout. Is anything wrong? so I know that was from a long time but google still drive me here and I saw there is none marked as

I have some kind of problem and I can't check this at home if its working or not. Here is the code using System; using System.Net; using System.Net.Sockets; using System.Threading; using System.IO; using System.Net.Security; class Program { private static IPAddress ipAddress = IPAddress.Parse("127.0.0.1"); private static int port = 6000; private static string data = null; static void Main(string[] args) { Thread thread = new Thread(new ThreadStart(receiveThread)); thread.Start(); Console.ReadKey(); } public static void receiveThread() { while (true) { TcpListener tcpListener = new TcpListener

all I am new to Android and now I am facing a strange problem, the problem in short is "Receive TCP message and then change background color of GUI has no effect once screen has been rotated." What I want to archive: Have a APP running on Android device, connect to a PC via TCP. PC can send a string to APP, the APP will then do something base on string received. In this case a string, "change back ground color to red(with phone vibrates)/black" is send to APP via TCP, so Android user will see a blinding effect with vibration. What is the problem: I can archive what I want. But once the screen

I'm trying to write a local proxy application. I know how proxy applications work in theory. I've done everything related to handle incoming connections. But the problem is how should I send request which client requested to specified Url. When I try to create a connection with TcpClient to specified Url and port, it throws following exception : No such host is known Edit : I think I should bypass the proxy something like FireFox is doing even system proxy set. Any idea will be helpful. Thanks in advance. Colin Smith These links might be of help: http://www.replicator.org/journal/201011170043
