communication

问题 I want to send/receive messages multiple TCP messages between the server and the client. For Example: Server: ip="" port=8888 buffersize=1024 s=socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.bind((myIP, myPort)) s.listen(1) (cl, adress) = s.accept() cl.send("hi!".encoded()) msg=cl.recv(bufferSize).decode() msg=msg[0] print(" Received message is '{}'".format(msg)) Client: ip="" port=8888 s=socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(ip,port) msg=s.recv(1024).decode() print

问题 I'm working on a project right now, and I am trying to make 2 callbacks communicate with each other by passing to them the same variable (the callbacks share the same variable). Since the callbacks cannot return a value, I have passed a pointer to the value which is assigned in the main loop (main function). However, it isn't working at all! This is my code: #include <gtk/gtk.h> static void inc_val (GtkWidget *widget, gpointer data) { int* value = data; *value++; printf("value is: %d\n",

问题 The binding works fine for title, subtitle, button.icon and button.name but not for button.action parent.component.html <app-title [title]="title" [subtitle]="subtitle" [buttons]="buttons"></app-title> parent.component.ts export class ParentComponent { actionOne() { ... } title = 'Title'; subtitle = 'Subtitle'; buttons = [ { 'name': 'Name1', 'icon': 'Icon1', 'action': 'actionOne()'}, { 'name': 'Name2', 'icon': 'Icon2', 'action': 'actionTwo()'}, { 'name': 'Name3', 'icon': 'Icon3', 'action':

问题 I have a problem using Pulpcore Java framework. I tried to call Java function from JavaScript on the page with applet. The applet is correctly embedded on the page (pulpcore generated the code). The JavaScript code is: $(document).ready(function() { var self = $("#pulpcore_object")[0]; self.show2(); }); I even debugged this code and it gets applet from DOM correctly, but then there is this JavaScript error: Uncaught exception: TypeError: 'self.show2' is not a function which makes me little

问题 I'm assuming that for every page request, the webserver (eg. Apache) creates a new instance of a script in memory. Can these instances communicate with each other while running? and pass data too? 回答1: If you want to pass data between scripts in PHP I suggest using either memcached or a database. Or possibly APC. If the scripts belong to the same session, they could theoretically communicate via the session but this would be effectively a one-way communication in most cases because only one

问题 I have an RMI application that has service implementation and it has a lot of code in it and I do not want to redo the business logic just to support an iPhone app. Could someone assist me on a best way to access these RMI services using Objective C? Or is there any other way for making this possible, please let me know if this is a terrible question, being a software programmer, I would expect that there would be a way for heterogeneous programs to communicate with each other, so this

问题 I have a simple MPICH program in which processes send & receive messages from each other in a Ring order. I've setup to 2 identical virtual machine, and made sure network is working fine. I've tested a simple MPICH program both machines and it works fine. The problem arises when I try to communicate between processes on different machines like the above program. I'm getting the following error: Fatal error in MPI_Send: A process has failed, error stack: MPI_Send(171)...............: MPI_Send

问题 I want to communicate two emulators via DatagramSocket in Android. Each of them is a Node in a P2P system. Thus each of them has a server Thread and client Thread (created per GUI event). This is how I create server public static final String SERVERIP = "10.0.2.15"; //... run() { InetAddress serverAddr = InetAddress.getByName(SERVERIP); DatagramSocket socket = new DatagramSocket(SERVERPORT,serverAddr); while(true) { byte[] buf = new byte[29]; DatagramPacket packet = new DatagramPacket(buf,

问题 I want to write an Android application that can display some data received(polled) from an internet resource. I guess that I need to write some logic that will periodically call and get data from some endpoint, parse the response and display it. Is there a good tutorial for all this steps? I know very little about Android programming at the momment and maybe it is better to start with something simpler. I just want to know what to look for while learning an gather some resources on this. 回答1:

问题 I have a Linux system and Windows system send text to each other and each one of them update a text file with the received text, now i have a problem when the text contain LF/CR char, i need to unify the newline char sent by both of them, i tried to use only \n (replacing \r by empty string before sending the string) but it doesn't work , is there a known solution for this issue ? 回答1: Don't unifying, just accommodate for it in every environment, like Git does. When sending from Windows to
