  • How to execute python script on the BaseHTTPSERVER created by python?

    - by user1731699
    I have simply created a python server with : python -m SimpleHTTPServer I had a .htaccess (I don't know if it is usefull with python server) with: AddHandler cgi-script .py Options +ExecCGI Now I am writing a simple python script : #!/usr/bin/python import cgitb cgitb.enable() print 'Content-type: text/html' print ''' <html> <head> <title>My website</title> </head> <body> <p>Here I am</p> </body> </html> ''' I make test.py (name of my script) an executed file with: chmod +x test.py I am launching in firefox with this addres: (http : //) 0.0.0.0:8000/test.py Problem, the script is not executed... I see the code in the web page... And server error is: localhost - - [25/Oct/2012 10:47:12] "GET / HTTP/1.1" 200 - localhost - - [25/Oct/2012 10:47:13] code 404, message File not found localhost - - [25/Oct/2012 10:47:13] "GET /favicon.ico HTTP/1.1" 404 - How can I manage the execution of python code simply? Is it possible to write in a python server to execute the python script like with something like that: import BaseHTTPServer import CGIHTTPServer httpd = BaseHTTPServer.HTTPServer(\ ('localhost', 8123), \ CGIHTTPServer.CGIHTTPRequestHandler) ###  here some code to say, hey please execute python script on the webserver... ;-) httpd.serve_forever() Or something else...

  • Low Throughput on Windows Named Pipe Over WAN

    - by MichaelB76
    I'm having problems with low performance using a Windows named pipe. The throughput drops off rapidly as the network latency increases. There is a roughly linear relationship between messages sent per second and round trip time. It seems that the client must ack each message before the server will send the next one. This leads to very poor performance, I can only send 5 (~100 byte) messages per second over a link with an RTT of 200 ms. The pipe is asynchronous, using multiple overlapped write operations (and multiple overlapped reads at the client end), but this is not improving throughput. Is it possible to send messages in parallel over a named pipe? The pipe is created using PIPE_TYPE_MESSAGE, would PIPE_READMODE_BYTE work better? Is there any other way I can improve performance? This is a deployed solution, so I can't simply replace the pipe with a socket connection (I've read that Windows named pipe aren't recommended for use over a WAN, and I'm wondering if this is why). I'd be grateful for any help with this matter.

  • How to detect that cookies are disabled in browser with AngularJS

    - by user2943082
    I use an AngularJS in my current project and try to implement feature which detects does cookies are disable in browser. I have tried to use an AngularJS module "ngCookies" for resolve this issue. The main idea of this feature is to try to create some cookie, then check does this cookie was created and show message if it wasn't. But it didn't worked. Controller: someProject.controller('CookieCtrl', ['$scope', '$cookieStore', function($scope, $cookieStore) { $scope.areCookiesEnabled = false; $cookieStore.put("TestCookie", "TestCookieText"); $scope.cookieValue = $cookieStore.get("TestCookie"); if ($scope.someValue) { $cookieStore.remove("TestCookie"); $scope.areCookiesEnabled = true; } }]); View: <div class="main" data-ng-controller="CookieCtrl"> <div class="warning_message" data-ng-show="!areCookiesEnabled"> <span data-ng-bind="areCookiesEnabled"></span> </div> </div> Can anybody tell me where is my mistake?

  • malloc:mmap(size=XX) failed (error code=12)

    - by Michel
    I have a memory problem in an iPhone app, giving me a hard time. Here is the error message I get: malloc: * mmap(size=9281536) failed (error code=12) * error: can't allocate region I am using ARC for this app, in case that might be useful information. The code (below) is just using a file in the Bundle in order to load a core data entity. The strange thing is the crash happens only after more than 90 loops; while it seems to mee that since the size of the "contents" in getting smaller and smaller, the memory request should also get smaller and smaller. Here is the code, if any one can see a flaw please let me know. NSString *path,*contents,*lineBuffer; path=[[NSBundle mainBundle] pathForResource:@"myFileName" ofType:@"txt"]; contents=[NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil]; int counter=0; while (counter<10000) { lineBuffer=[contents substringToIndex:[contents rangeOfCharacterFromSet:[NSCharacterSet newlineCharacterSet]].location]; contents=[contents substringFromIndex:[lineBuffer length]+1]; newItem=[NSEntityDescription insertNewObjectForEntityForName:@"myEntityName" inManagedObjectContext:context]; [newItem setValue:lineBuffer forKey:@"name"]; request=[[NSFetchRequest alloc] init]; [request setEntity: [NSEntityDescription entityForName:@"myEntityName" inManagedObjectContext:context]]; error=nil; [context save:&error]; counter++; }

  • JSP includes and MVC pattern

    - by xingyu
    I am new to JSP/Servlets/MVC and am writing a JSP page (using Servlets and MVC pattern) that displays information about recipies, and want the ability for users to "comment" on it too. So for the Servlet, on doGet(), it grabs all the required info into a Model POJO and forwards the request on to a JSP View for rendering. That is working just fine. I'd like the "comment" part to be a separate JSP, so on the RecipeView.jsp I can use to separate these views out. So I've made that, but am now a little stuck. The form in the CommentOnRecipe.jsp posts to a CommentAction servlet that handles the recording of the comment just fine. So when I reload the Recipe page, I can see the comment I just made. I'd like to: Reload the page automatically after commenting (no AJAX for now) Block the user from making more than one comment on each Recipe over a 1 day timeframe (via a Cookie). So I store a cookie indicating the product ID whenever the user makes a comment, so we can check this later? How would it work in a MVC context? Show a message to the user that they have already commented on the Recipe when they visit one which they have commented on I'm confused about using beans/including JSPs etc on how to achieve this. I know in ASP.NET land, it would be a UseControl that I would place on a page, or in ASP.NET MVC, it would be a PartialView of some sort. I'm just confused with the way this works in a JSP/Servlets/MVC context.

  • Indy client receive string

    - by Eszee
    Im writing an Indy chat app, and am wondering if there is a way for the server component to tell the client that there is a string waiting, or even a way for the client to have an "OnExecute" like event. This is what i have now: server: procedure TServer.ServerExecute(AContext: TIdContext); var sResponse: string; I: Integer; list: Tlist; begin List := Server.Contexts.LockList; sResponse:= AContext.Connection.Socket.ReadLn; try for I := 0 to List.Count-1 do begin try TIdContext(List[I]).Connection.IOHandler.WriteLn(sResponse); except end; end; finally Server.Contexts.UnlockList; end; end; Client: procedure TForm1.Button1Click(Sender: TObject); var sMsg : string; begin Client.Socket.WriteLn(edit1.Text); sMsg := Client.Socket.ReadLn; Memo1.Lines.Add(sMsg); end; The problem is when i have 2 or more clients running the messages keep stacking because the button only processes 1 message a time. I'd like a way for the client to wait for messages and when it is triggered it processes those messages, like it does now under the button procedure. I've tried to put the "readln" part under a timer, but that causes some major problems. Im Using Delphi 2010 and Indy 10

  • My website keeps crashing IE, can't debug

    - by Ninja rhino
    I have a website that suddenly started to crash internet explorer. The website loads and starts executing javascript but somewhere in there the machinery explodes. I don't even get a script error, it just crashes. I've tried to manually step through every single line of js with the built in debugger but then of course the problem doesn't occur. If i choose to debug the application when it crashes i see the following message. Unhandled exception at 0x6c5dedf5 in iexplore.exe: 0xC0000005: Access violation reading location 0x00000090. The top 5 items in the call stack looks like this VGX.dll!6c5dedf5() [Frames below may be incorrect and/or missing, no symbols loaded for VGX.dll] VGX.dll!6c594d70() VGX.dll!6c594f63() VGX.dll!6c595350() VGX.dll!6c58f5e3() mshtml.dll!6f88dd17() VGX.dll seems to be part of the vml renderer and i am in fact using VML. I'm not suprised because i've had so many problems with vml, attributes has to be set in specific order, sometimes you cant set attributes when you have elements attached to the dom or vice versa (everything undocumented btw) but then the problems can usually be reproduced when debugging but not now :( The problem also occurs in no plugin-mode. Is there a better approach than trial and error to solve this? Edit: Adding a console outputting every suspect modification to the DOM made the problem only occur sometimes. (the console is also implemented in javascript on the same page, i'm able to see the output even after a crash as the window is still visible) Apparently it seems to be some kind of race condition. I managed to track it down even further, and it seems to occur when you remove an object from the DOM too quickly after it's just been added. (most likely only for vml-elements with some special attribute, didn't try further) And it can't be fixed by adding a dead loop in front of removeChild(pretty bad solution anyway), the page has to be rendered by the browser once after the addChild before you can call removeChild. sigh

  • Tips for using Subversion and XCode in a team project

    - by FelipeUY
    Hi to all. I've been working on an Xcode (iPhone) project with three different persons. We have the project on a Subversion repository, but we still don't completely understand some aspects of the Subversion + Xcode methodology: 1) Each time someone does a commit on a single file, it may appear or not in the project of the other developers. Even though the same person that creates the new files, it adds those files to the Repository and then it commits on those files. Why does that happens? Any suggestions? 2) Each person that is involved on the project can't do a "Commit entire project" without causing a considerable headache to the rest of the developers... any idea how this should be done?. The working methodology that we are trying to implement is that only one developer (generally the leader of the project) can Commit the entire project but he must inform the rest of the team, so everybody can be prepared to receive a message asking him to discard his changes and read the new files from the repository. I need suggestions or advice on how to handle a project with multiple developers using subversion. We have read the Subversion handbook, and many other messages on StackOverflow but I still can't find any useful advice. Thanks for any tip!

  • formmail to email in database

    - by aarontb
    Here's what I need to setup...and I am not well versed in PHP/SQL...but this is what I'm trying to do. On the New User database, I will have a section where they can have information sent to their phone using the provider's default e-mail to text msg (i.e. [email protected].) New User: Input number: ______________(2225551212 format, no hyphens, etc.) Select Provider: (Drop-down menu with proper @provider.ext...) Then the formmail, when sent, if for specific user will get ($phone".@."$provider); or something like that and send a preset message like: $user."requested information on ".$product."on".$date." at ".$time."."; Is this possible? The $user, $product, $date, $time all are generated directly from the most recent input page for a database. Is this possible? Please help!

  • How to read/write from erlang to a named pipe ?

    - by cstar
    I need my erlang application to read and write through a named pipe. Opening the named pipe as a file will fail with eisdir. I wrote the following module, but it is fragile and feels wrong in many ways. Also it fails on reading after a while. Is there a way to make it more ... elegant ? -module(port_forwarder). -export([start/2, forwarder/2]). -include("logger.hrl"). start(From, To)-> spawn(fun() -> forwarder(From, To) end). forwarder(FromFile, ToFile) -> To = open_port({spawn,"/bin/cat > " ++ ToFifo}, [binary, out, eof,{packet, 4}]), From = open_port({spawn,"/bin/cat " ++ FromFifo}, [binary, in, eof, {packet, 4}]), forwarder(From, To, nil). forwarder(From, To, Pid) -> receive {Manager, {command, Bin}} -> ?ERROR("Sending : ~p", [Bin]), To ! {self(), {command, Bin}}, forwarder(From, To, Manager); {From ,{data,Data}} -> Pid ! {self(), {data, Data}}, forwarder(From, To, Pid); E -> ?ERROR("Quitting, first message not understood : ~p", [E]) end. As you may have noticed, it's mimicking the port format in what it accepts or returns. I want it to replace a C code that will be reading the other ends of the pipes and being launched from the debugger.

  • In Safari, using jQuery a Form Input Text Field does not receive focus after alert is displayed. Why

    - by Rob
    I have an ASPX web form. I use jQuery to simply my Javascript. I use a Javascript validation script to validate each of the form fields' values. If an error occurs, I popup an alert with an error message. Then I transfer focus to the underlying element. Here are examples I have tried. Using jQuery: var Form_FieldDef = function(name) { this.name = name; this.SetFocus = function() { $('#' + this.name)[0].focus(); } this.Validate = function() { var isvalid = true; if ( $.trim($('#' + this.name).val()) == '') { alert("Your entry is empty"); this.SetFocus(); isvalid = false; } return isvalid; } } This works on IE7, IE8, Opera, Chrome, and Firefox. It does not work on Safari 4 on PC. I don't have a Mac. So I changed the SetFocus method to this. this.SetFocus = function() { var fld = document.getElementById(this.name); if (fld != null) fld.focus(); } This works on IE7, IE8, Opera, Chrome, and Firefox. It does not work on Safari 4 on PC. I stepped through the code with VS 2008 debugger, and I'm calling the focus method on the underlying element.

  • Instantiate a form, then find it later, without showing it initially

    - by awilson53
    I am having a problem that is strange to me but hopefully is not so strange to someone else. : ) Some background: I am working on a simple IM client that allows the user to broadcast messages to multiple recipients. The goal is to create a chat form for each of the recipients containing the text of the broadcast message, then show that form only if the recipient responds to the broadcast-er. However, when the application receives a response then attempts to locate the form for that particular chat session (using Application.OpenForms) it cannot find it UNLESS I .Show at the time it is created. I would like to avoid having to show this form when it is created because this means that the user will see a flash on the screen. The form doesn't seem to really be created until I show it, but it would seem there has to be a way to do this without showing first. Can anyone assist? I can provide code snippets if needed, I didn't in this post because this feels more like a conceptual misunderstanding on my part than a bug in the code. Thanks in advance!

  • Tkinter, Python: How do I save text entered in the Entry widget? How do I move a label?

    - by user3692825
    I am a newbie at programming and my program is not stellar but hopefully it's ok because I have only been using it for a couple days now. I am having trouble in my class "Recipie". In this class I am having trouble saving the text in my Entry widget. I know to use the .get() option but when I try to print it, it doesn't (whether it is within that defined method or not). So that is my main concern. I want it to save the text entered as a string when I press the button: b. My other minor question is, how can I move the label. When I have tried I have used the height and width options, but that just expands the label. I want to move the text to create a title above my Entry boxes. Is label the right widget to use or would it be easier to use a message box widget? So it would look like, for example (but like 8 pixels down and 20 to the right): ingredients textbox button labeled as: add an ingredient And I am not sure the option .pack(side="...") or .place(anchor="...") are the right options to use for my buttons or entry boxes or labels. Any help is greatly appreciated!!! And if you could add comments to your code explaining what you did, that would be so helpful. Thank you!!! import Tkinter class Recipie(Tkinter.Tk): def __init__(self): Tkinter.Tk.__init__(self) self.title("New Recipie") self.geometry("500x500") def name(self): name = Tkinter.Label(self, text="Title:", width=39) name.place(anchor="nw") insert_name = Tkinter.Entry(self) insert_name.pack() insert_name.focus_set() def ingredients(self): e = Tkinter.Entry(self) e.pack() e.focus_set() def addingredient(self): but = Tkinter.Button(self, text="Add Ingredients", width=15, command=self.ingredients) but.pack(side="bottom") def procedure(self): txt = Tkinter.Label(self, text="List the Steps:") txt.place(anchor="n") p = Tkinter.Entry(self) p.place(anchor="nw") p.focus_set() def savebutton(self): print insert_name.get() print e.get() print p.get() b = Tkinter.Button(self, text="Save Recipie", width=15, command=savebutton) top = Recipie() top.mainloop()

  • C As Principal Class For Mac App

    - by CodaFi
    So, I've got a c file raring to go and be the main class behind an all-C mac-app, however, a combination of limiting factors are preventing the application from being launched. As it currently stands, the project is just a main.m and a class called AppDelegate.c, so I entered "AppDelegate" as the name of the principal class in the info.plist, and to my complete surprise, the log printed: Unable to find class: AppDelegate, exiting This would work perfectly well in iOS, because the main function accepts the name of a delegate class, and handles it automatically, but NSApplicationMain() takes no such argument. Now, I know this stems from the fact that there are no @interface/@implementation directives in C, and that's really what the OS seems to be looking for, so I wrote a simple NSApplication subclass and provided it as the Principal Class to the plist, and it launched perfectly well. My question is, how could one go about setting a c file as the principal class in a mac application and have it launch correctly? PS, don't ask what or why I'm doing this for, the foundation must be dug. For @millimoose's amusement, here be the AppDelegate.c file: #include <objc/runtime.h> #include <objc/message.h> struct AppDel { Class isa; id window; }; // This is a strong reference to the class of the AppDelegate // (same as [AppDelegate class]) Class AppDelClass; BOOL AppDel_didFinishLaunching(struct AppDel *self, SEL _cmd, void *application, void *options) { self->window = objc_msgSend(objc_getClass("NSWindow"), sel_getUid("alloc")); self->window = objc_msgSend(self->window, sel_getUid("init")); objc_msgSend(self->window, sel_getUid("makeKeyAndOrderFront:"), self); return YES; }

  • Java Detect Variable Change Using PropertyChangeSupport and PropertyChangeListener

    - by Sam
    I'm trying to print out debug statements when some third party code changes a variable. For example, consider the following: public final class MysteryClass { private int secretCounter; public synchronized int getCounter() { return secretCounter; } public synchronized void incrementCounter() { secretCounter++; } } public class MyClass { public static void main(String[] args) { MysteryClass mysteryClass = new MysteryClass(); // add code here to detect calls to incrementCounter and print a debug message } I don't have the ability to change the 3rd party MysteryClass, so I thought that I could use PropertyChangeSupport and PropertyChangeListener to detect changes to the secretCounter: public class MyClass implements PropertyChangeListener { private PropertyChangeSupport propertySupport = new PropertyChangeSupport(this); public MyClass() { propertySupport.addPropertyChangeListener(this); } public void propertyChange(PropertyChangeEvent evt) { System.out.println("property changing: " + evt.getPropertyName()); } public static void main(String[] args) { MysteryClass mysteryClass = new MysteryClass(); // do logic which involves increment and getting the value of MysteryClass } } Unfortunately, this did not work and I have no debug messages printed out. Does anyone see what is wrong with my implementation of the PropertyChangeSupport and Listener interfaces? I want to print a debug statement whenever incrementCounter is called or the value of secretCounter changes.

  • How can i initialise a server on startup?

    - by djerry
    Hey all, I need to make some connections on startup of a server. I'm using the wcf technology for this client-server application. The problem is that the constructor of the server isn't called at any time, so for the moment, i initialize the connections when the first client makes a connection. But this generates problems in a further part. This is my server setup: private static ServiceHost _svc; static void Main(string[] args) { NetTcpBinding binding = new NetTcpBinding(SecurityMode.Message); Uri address = new Uri("net.tcp://localhost:8000"); _svc = new ServiceHost(typeof(MonitoringSystemService), address); publishMetaData(_svc, "http://localhost:8001"); _svc.AddServiceEndpoint(typeof(IMonitoringSystemService), binding, "Monitoring Server"); _svc.Open(); Console.WriteLine("Listener service gestart op net.tcp://localhost:8000/Monitoring"); Console.ReadLine(); } private static void publishMetaData(ServiceHost svc, string sEndpointAddress) { ServiceMetadataBehavior smb = svc.Description.Behaviors.Find<ServiceMetadataBehavior>(); if (smb != null) { smb.HttpGetEnabled = true; smb.HttpGetUrl = new Uri(sEndpointAddress); } else { smb = new ServiceMetadataBehavior(); smb.HttpGetEnabled = true; smb.HttpGetUrl = new Uri(sEndpointAddress); svc.Description.Behaviors.Add(smb); } } How can i start the server without waiting for a client to logon so i can initialize it. Thanks in advance.

  • C++: Declare static variable in function argument list

    - by MDC
    Is there any way at all in C++ to declare a static variable while passing it to a function? I'm looking to use a macro to expand to the expression passed to the function. The expression needs to declare and initialize a static variable on that particular line (based on the filename and line number using FILE and LINE). int foo(int b) { int c = b + 2; return c; } int main() { int a = 3; a = foo(static int h = 2); //<---- see this! cout << a; return 0; } The problem I'm trying to solve is getting the filename and line number with the FILE and LINE macros provided by the preprocessor, but then creating a lookup table with integer keys leading to the FILE, LINE pairs. For example, the key 89 may map to file foo.cpp, line 20. To get this to work, I'm trying to use local static variables, so that they are initialized only once per line execution. The static variable will be initialized by calling a function that calculates the integer key and adds an entry to the lookup table if it is not there. Right now the program uses a message class to send exception information. I'm writing a macro to wrap this class into a new class: WRAPPER_MACRO(old_class_object) will expand to NewClass(old_class_object, key_value). If I add the static variable declaration as a second line right before this, it should work. The problem is that in most places in the code, the old class object is passed as an argument to a function. So the problem becomes declaring and initializing the static variable somehow with the macro, while keeping the existing function calls.

  • "Permission denied" with Internet Explorer and jQuery

    - by rallex
    I try to do an AJAX call with jQuery and $.post in Internet Explorer, but all I get is an error saying "Permission denied". The problem is kinda weird since it occurs only when I access a page after I was on any other page. For instance I type the URL in the adress line and let IE load the page. Then I click on a button so the script should start loading JSON data. (The script providing the data lies on the same server and I access it with a relative URL, so using a different domain is not the problem here. Even tried to use a absolute URL with the same host part.) But when I refresh the page then and try it again it works! Same thing when I come to that page from another page. At first nothing works, but when I click "refresh" everything is fine. IE gives me the error message "Permission denied" while in every other browser I don't notice this behaviour. Since I have tried many things and still cannot imagine where the problem lies I'd like to ask you what you think the problem might be?

People - Has a corresponding person_id I am trying to figure out how to do the following in a single linq query: Give me all messages that have been sent to and from person x (idself). I had a couple of cracks at this. Not quite right MsgPeople = (from p in db.people join m in db.messages on p.person_id equals m.from_id where (m.from_id == idself || m.to_id == idself) orderby p.name descending select p).Distinct(); This almost works, except I think it misses one case: "people who have never received a message, just sent one to me" How this works in my head So what I really need is something like: join m in db.messages on (p.people_id equals m.from_id or p.people_id equals m.to_id) Gets me a subset of the people I am after It seems you can't do that. I have tried a few other options, like doing two joins: MsgPeople = (from p in db.people join m in AllMessages on p.person_id equals m.from_id join m2 in AllMessages on p.person_id equals m2.to_id where (m2.from_id == idself || m.to_id == idself) orderby p.name descending select p).Distinct(); but this gives me a subset of the results I need, I guess something to do with the order the joins are resolved. My understanding of LINQ (and perhaps even database theory) is embarrassingly superficial and I look forward to having some light shed on my problem.

  • How to access remote mysql host on Ubuntu inside VMware?

    - by Nick Grossman
    Hi, I'm running Ubuntu 10.10 inside VMware fusion on Mac OSX Snow Leopard. Inside ubuntu, I'm attempting to use command-line mysql to connect to a database hosted on a separate web server. For some reason, mysql misinterprets the remote hostname as a local address, and is not able to connect to the database. Steps: (from ubuntu inside VMware) mysql -u <my-username> -h mysql-2.sandbox.wrkng.net -p Enter Password: <my password> expected: to log into mysql got: ERROR 1045 (28000): Access denied for user '<my-username>'@'c-71-233-98-90.hds1.ma.comcast.net' (using password: YES) Note that the hostname referenced in the error message is different than the one I inputted to the mysql command. Also, performing the same command from the Mac (host of the VM) terminal successfully connects to the database. I am not seasoned with VMware or linux, so I may be missing something obvious here -- it seems like somewhere along the way either ubuntu or the VM has a networking issue. Note also that accessing the internet via ubuntu inside the VM works fine. Any help is greatly appreciated. Thanks!

  • How to read pair in freemarker

    - by Lukasz Rys
    Ok i'm having little trouble with reading pair. So I'm creating my pair private Pair<Integer, Integer> count(somethink) { int c1 = 2; int c2 = 4; return new Pair<Integer, Integer>(c1, c2); } And 'sending' it to ftl via java mv.addObject("counted", count(somethink)); I won't write everythink how it sends because I dont think it really matters with my issue. So i'm recieving it in "ftl". Then i was trying to 'read' it <#list counted?keys as key> <a href="#offerOrderTab"><@spring.message "someMsg"/>(${key}/${counted[key]})</a> </#list> After then i'm getting error Expecting a string, date or number here, Expression x is instead a freemarker.ext.beans.SimpleMethodModel As i suppose you dont iterate pairs (or I'm wrong?) i know its pair that contains only one key and one value but still i have to do send it that way and I thought its goin be to similar to iterating through map, in java i would use pair.first() and pair.second() but it doesn't work in ftl (ye i know it shouldnt work). I also tried to cast it to String by using ?string but it didnt work too

  • Concurrent connections in C# socket

    - by Chu Mai
    There are three apps run at the same time, 2 clients and 1 server. The whole system should function as following: The client sends an serialized object to server then server receives that object as a stream, finally the another client get that stream from server and deserialize it. This is the sender: TcpClient tcpClient = new TcpClient(); tcpClient.Connect("127.0.0.1", 8888); Stream stream = tcpClient.GetStream(); BinaryFormatter binaryFormatter = new BinaryFormatter(); binaryFormatter.Serialize(stream, event); // Event is the sending object tcpClient.Close(); Server code: TcpListener listener = new TcpListener(IPAddress.Parse("127.0.0.1"), 8888); listener.Start(); Console.WriteLine("Server is running at localhost port 8888 "); while (true) { Socket socket = listener.AcceptSocket(); try { Stream stream = new NetworkStream(socket); // Typically there should be something to write the stream // But I don't knwo exactly what should the stream write } catch (Exception e) { Console.WriteLine("Exception: " + e.Message); Console.WriteLine("Disconnected: {0}", socket.RemoteEndPoint); } } The receiver: TcpClient client = new TcpClient(); // Connect the client to the localhost with port 8888 client.Connect("127.0.0.1", 8888); Stream stream = client.GetStream(); Console.WriteLine(stream); when I run only the sender and server, and check the server, server receives correctly the data. The problem is when I run the receiver, everything is just disconnected. So where is my problem ? Could anyone point me out ? Thanks
