问题 I am writing a simple TCP/IP server using Powershell. I notice that Ctrl-C cannot interrupt the AcceptTcpClient() call. Ctrl-C works fine after the call though. I have searched around, nobody reported similar problem so far. The problem can be repeated by the following simple code. I am using Windows 10, latest patch, with the native Powershell terminal, not Powershell ISE. $listener=new-object System.Net.Sockets.TcpListener([system.net.ipaddress]::any, 4444) $listener.start() write-host

问题 I am converting a Java desktop project to Android. Part of it includes a TCP connection to a server and parsing a long text from the server to the client (the Android application). This is the code that I have for the desktop project that I also try to use in Android: // Method is called when a button is tapped public void tapButton() { // Create a message to the server that requests for the Departure navdata String messageToServer = someMethodToMakeHandshakeMessage(); // Connect to the

问题 I am attempting to stream audio using Naudio over a TCP connection. The problem is the audio sounds choppy. I believe this is because I am getting an exception saying the buffer is full when I try to add samples to the bufferedwaveprovider. I have tried increasing the buffer size however the result remains unchanged. -----CLIENT CODE----- public TcpClient client; public WaveOut waveplayer = new WaveOut(); public BufferedWaveProvider bwp = new BufferedWaveProvider(new WaveFormat(8000, 16, 1));

问题 I like being able to work with my android phone using ADB over WIFI. After connecting it via USB, I run adb tcpip 5555 , and then I can disconnect the USB and run adb connect {phone's IP}:5555 . What I don't like is that every time I have to restart my phone, I have to reconnect the USB and rerun adb tcpip 5555 command. Is there any way to make it remember the 5555 setting so it's always in "TCP mode port 5555"? Thanks EDIT: my phone is Android 9 limited. Is not rooted. Tried ADB over WIFI

问题 when with portfowarding the websocket pass by internet and only send when the connexion is close (on my network it's like that), I first try to close the websocket by closing chrome(it worked), so now i found terminate that i think can do the same than closing the webbrowser,but it's only for the serveur that have this function and the problem is that the buffer with close is not 0 but 13... so how can i do a hard close with ws.terminate or something else to flush the buffer to 0 and a basic

问题 I spent the last days trying to figure out how to download a file from an URL. This is my first challenge with socket and I'm using it to have an understanding of protocols so I would like to do it without cURL libraries and only in C language!! I searched a lot....now I'm able to printf the source code of a page but I think it's different with a file, I don't have only to put the received data from a buffer to a file, right? any tips? #include <sys/socket.h> #include <sys/types.h> #include

问题 I have some documents which I have to fetch from mongodb and set it to memcache.
