broadcasting

问题 I'm testing a simple socket setup in which a server listens on a specified port, and a client sends a broadcast packet which should be received by that server. This setup works fine when sending messages directly (i.e. not broadcasting), but when broadcasting the packet is never received on the server. Some of the code (trimmed down with error checking removed, for simplicity): // Client (broadcast sender) // Create and bind the client socket clientSocket = socket(AF_INET, SOCK_DGRAM, IPPROTO

问题 In my app, I set an alarm AlarmManager alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); ... PendingIntent pendingIntent = PendingIntent.getBroadcast(context, id, intent, PendingIntent.FLAG_UPDATE_CURRENT); ... alarmMgr.set(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(), pendingIntent); It works fine unless I turn off and turn on the phone. To be more specific, let's say at 10:20, I set an alarm to 10:22 and I turn off and turn on the phone at 10:21, alarm won't work.

问题 I want to plug a live video broadcasting facility to a website. I'm planning to use silverlight and C# but I'm very newbie in this topic. What is the best way to do this? Thanks in advance.

问题 Its my first time programing network in java. I was looking for a way to send to somehow broadcast to all nodes in the whole networking. To let them know of my existence. I'm trying to make a multiplayer network game, and I want the clients to be able to see all the games available to choose which one to join. I want to know how to broadcast from the server and also how to make the clients listen. Please make it simple, I'm a newbie :) Thanks in advance. 回答1: To broadcast data packets, send

问题 I have a problem with which I've been struggling. It is related to tf.matmul() and its absence of broadcasting. I am aware of a similar issue on https://github.com/tensorflow/tensorflow/issues/216, but tf.batch_matmul() doesn't look like a solution for my case. I need to encode my input data as a 4D tensor: X = tf.placeholder(tf.float32, shape=(None, None, None, 100)) The first dimension is the size of a batch, the second the number of entries in the batch. You can imagine each entry as a

问题 Guys am having some difficulty figuring this out: I am trying to test whether the code(in c#) to broadcast a message and receiving the message works: The code to send the datagram(in this case its the hostname) is: public partial class Form1 : Form { String hostName; byte[] hostBuffer = new byte[1024]; public Form1() { InitializeComponent(); StartNotification(); } public void StartNotification() { IPEndPoint notifyIP = new IPEndPoint(IPAddress.Broadcast, 6000); hostName = Dns.GetHostName();

问题 I need to know what are the security risks of using unauthorized event broadcasting in Laravel . I'm using angular-js for my front-end and Laravel as back-end API, I'm intending to use Laravel event broadcasting (socket.io + redis), I want to know is there any security risk, if I broadcast unimportant, public data to the front-end while it's not authenticated? Thanks in advance. 回答1: I don't think the paradigm is really any different from a traditional web application or API. The same

问题 I am working on a broadcast beacon in C# that is supposed to broadcast server information to all listening devices. The information sent will contain information like the URL of a WCF service, the namespace, a list of required arguments etc. What I have right now is a sender and receiver that can talk perfectly fine when they are on the same computer. However, once I put the sender on another computer than my receiver, the sender sends its message but my receiver never gets it. There are no

问题 I get "Illuminate\Broadcasting\BroadcastException" when trying to broadcast event. I've checked my .env file - it's set correctly, I'm on localhost so I set 'encrypted' to false aswell, BroadcastServiceProvider is uncommented. Nothing helps. FULL ERROR IMAGE bootstrap.js import Echo from 'laravel-echo' window.Pusher = require('pusher-js'); window.Echo = new Echo({ broadcaster: 'pusher', key: '***', cluster: 'mt1', encrypted: false }); web.php Route::post('/messages', function() { $user = Auth

问题 I spent the last two days reading each StackOverflow questions and answers (and googling of course) about Indy TCP and UDP protocol in order to decide which one should I use in my communication method between my User Application and my Windows Service. From what I saw so far, UDP is the easiest and the only one I managed to work to receive broadcast messages from TidUDPClient (I did not testes the response back yet). And I also noticed that TCP is a bit more complicated with it's thread loop.
