  • calling a method from an event handler

    - by Ayoub
    I have this code i am working on but every time i call init method I keep getting an error this.addElement is not a function is it because i can't call methods from event handlers ? function editor () { this.init = function () { $("#area").bind('click' , this.click_event ); } this.addElement = function () { console.log("adding element"); } this.click_event = function(event) { this.addElement(); console.log("click event in x : "+event.data); } }

  • nServiceBus - Not all commands being received by handler

    - by SimonB
    In a test project based of the nServiceBus pub/sub sample, I've replace the bus.publish with bus.send in the server. The server sends 50 messages with a 1sec wait after each 5 (ie 10 burst of 5 messages). The client does not get all the messages. The soln has 3 projects - Server, Client, and common messages. The server and client are hosted via the nServiceBus generic host. Only a single bus is defined. Both client and server are configured to use StructureMap builder and BinarySerialisation. Server Endpoint: public class EndPointConfig : AsA_Publisher, IConfigureThisEndpoint, IWantCustomInitialization { public void Init() { NServiceBus.Configure.With() .StructureMapBuilder() .BinarySerializer(); } } Server Code : for (var nextId = 1; nextId <= 50; nextId++) { Console.WriteLine("Sending {0}", nextId); IDataMsg msg = new DataMsg { Id = nextId, Body = string.Format("Batch Msg #{0}", nextId) }; _bus.SendLocal(msg); Console.WriteLine(" ...sent {0}", nextId); if ((nextId % 5) == 0) Thread.Sleep(1000); } Client Endpoint: public class EndPointConfig : AsA_Client, IConfigureThisEndpoint, IWantCustomInitialization { public void Init() { NServiceBus.Configure.With() .StructureMapBuilder() .BinarySerializer(); } } Client Clode: public class DataMsgHandler : IMessageHandler<IDataMsg> { public void Handle(IDataMsg msg) { Console.WriteLine("DataMsgHandler.Handle({0}, {1}) - ({2})", msg.Id, msg.Body, Thread.CurrentThread.ManagedThreadId); } } Client and Server App.Config: <MsmqTransportConfig InputQueue="nsbt02a" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" /> <UnicastBusConfig DistributorControlAddress="" DistributorDataAddress=""> <MessageEndpointMappings> <add Messages="Test02.Messages" Endpoint="nsbt02a" /> </MessageEndpointMappings> </UnicastBusConfig> All run via VisualStudio 2008. All 50 messages are sent - but after the 1st or 2nd batch. only 1 msg per batch is sent? Any ideas? I'm assuming config or misuse but ....?

  • Event handler triggered twice instead of once

    - by kwokwai
    Hi all, I am sorry that I have asked two questions in a few minutes. In a html file, I got three child DIV tags in a parent DIV tag: <div id="container"> <div id="frag-123">123</div> <div id="frag-124">124</div> <div id="frag-125">125</div> </div> Now when I click either the three child DIV tags, I will see two alert boxes pop up instead of one: The first alert box will show something like this: frag-123, and the second alert box will show something like this: container I dont know why. I just want to get the ID value of a child DIV, not the one from the parent DIV. <script> $(function() { $("div").click(function() { var imgID = this.id; alert(imgID); }); }); </script> Please help.

  • URL protocol handler shell execute problem

    - by Chuck
    Hi, I'm working on a small hobby web site where I'm able to launch a local app with certain arguments based on links. Setting up a protocol wasn't difficult, as described in http://msdn.microsoft.com/en-us/library/aa767914(VS.85).aspx, but I have one dilemma: Let's say the protocol is: foo:127.0.0.1:1111, so a link like href="foo:127.0.0.1:1111" would launch an app like: bar.exe "%1". Since I don't have any control over bar.exe (if I had, then it would be no problem to just parse it, obviously), I need some help parsing %1. bar.exe will launch correctly if it's run as bar.exe 127.0.0.1:1111, but not if it's run as bar.exe foo:127.0.0.1:1111. So I guess my question is... is there ANY way to tell the registry to pass on not %1, but a trimmed %1? (Thinking in terms of regexp where you have match[0] = all of the matched, match[1] = first capture in the matched text). I can solve it by having a .bat instead of .exe, but as I would like to make it as easy as possible for the user to use, I would LOVE it if I could handle it all stricly in registry. Any help is greatly appreciated! Chuck

  • Design: How to declare a specialized memory handler class

    - by Michael Dorgan
    On an embedded type system, I have created a Small Object Allocator that piggy backs on top of a standard memory allocation system. This allocator is a Boost::simple_segregated_storage< class and it does exactly what I need - O(1) alloc/dealloc time on small objects at the cost of a touch of internal fragmentation. My question is how best to declare it. Right now, it's scope static declared in our mem code module, which is probably fine, but it feels a bit exposed there and is also now linked to that module forever. Normally, I declare it as a monostate or a singleton, but this uses the dynamic memory allocator (where this is located.) Furthermore, our dynamic memory allocator is being initialized and used before static object initialization occurs on our system (as again, the memory manager is pretty much the most fundamental component of an engine.) To get around this catch 22, I added an extra 'if the small memory allocator exists' to see if the small object allocator exists yet. That if that now must be run on every small object allocation. In the scheme of things, this is nearly negligable, but it still bothers me. So the question is, is there a better way to declare this portion of the memory manager that helps decouple it from the memory module and perhaps not costing that extra isinitialized() if statement? If this method uses dynamic memory, please explain how to get around lack of initialization of the small object portion of the manager.

  • Suppressing .net's updatepanel submit event handler

    - by wheresrhys
    I'm performing some custom js validation on my forms, triggered by submitting the form $("form").submit(function (e) { var validates = true; // validation code goes in here if (!validates) { e.preventDefault(); e.stopImmediatePropagation(); return false; } }) None of the lines I've included to stop the submit event prevent the .NET control posting back. Is there some way (using js or setting a property in the updatepanel control) of stopping post back?

  • jquery event handler- trigger function upon specific key and action

    - by Gal
    Background story: when a user selects a portion of text in a text field with her mouse (mark it up manually), and subsequently hits "alt" key, a certain function would trigger. My questions are: How can I trigger a function when a user hits a key (in her keyboard)? How can I preserve a portion of text selected, and use it as a parameter for that function? I've tried looking up online but haven't found any good answers, but i'd greatly appreciate links as well.

  • HTTP request stream not readable outside of request handler

    - by Jason Young
    I'm writing a fairly complicated multi-node proxy, and at one point I need to handle an HTTP request, but read from that request outside of the "http.Server" callback (I need to read from the request data and line it up with a different response at a different time). The problem is, the stream is no longer readable. Below is some simple code to reproduce the issue. Is this normal, or a bug? function startServer() { http.Server(function (req, res) { req.pause(); checkRequestReadable(req); setTimeout(function() { checkRequestReadable(req); }, 1000); setTimeout(function() { res.end(); }, 1100); }).listen(1337); console.log('Server running on port 1337'); } function checkRequestReadable(req) { //The request is not readable here! console.log('Request writable? ' + req.readable); } startServer();

  • Hooking a synchronous event handler on a form submit button in JS

    - by Xzhsh
    Hi, I'm working on a security project in javascript (something I honestly have not used), and I'm having some trouble with EventListeners. My code looks something like this: function prevclick(evt) { evt.preventDefault(); document.loginform.submitbtn.removeEventListener('click',prevclick,false); var req = new XMLHttpRequest(); req.open("GET","testlog.php?submission=complete",false); req.send(); document.loginform.submitbtn.click(); //tried this and loginform.submit() } document.loginform.submitbtn.addEventListener('click',prevclick,false); But the problem is, the submit button doesn't submit the form on the first click (it does, however, send the http request on the first click), and on the second click of the submit button, it works as normal. I think there is a problem with the synchronization, but I do need to have the request processed before forwarding the user to the next page. Any ideas on this would be great. Thanks in advance.

  • Is there a more modern regexp handler for Open Object Rexx

    - by Brent.Longborough
    The regular expression class (rxregexp.dll) that comes with ooRexx (I'm on 4.0.0) is relatively low on function compared, say, with Python's re module (even at 2.5.2). It appears to have no assertions, no facilities for group extraction, or for substitution. Greedy or lazy matching is a global pattern option, rather than flagged by an additional "?". Basically, a pre-PCRE regular expression engine. Does anyone know if anything with more up-to-date function is available?

  • ListView in Android, handler for clicking item

    - by eljainc
    Hello, I have an activity in Android which uses a ListView. When I click on an item in the ListView, I would like to be able to determine which item was clicked. I have the following code: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); setContentView(R.layout.listr); //setupDB(); // populateList3(); ListView lv = (ListView) findViewById(R.id.ListView01); lv.setClickable(true); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Toast.makeText(ListRecords.this,"Clicked!", Toast.LENGTH_LONG).show(); } }); } My XML code: xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/Linear03lr" android:layout_width="fill_parent" android:orientation="vertical" android:gravity="center" android:layout_height="fill_parent"> android:layout_width="wrap_content" android:layout_height="400dp" / <Button android:id="@+id/previousbutton" android:gravity="center_horizontal" android:layout_width = "fill_parent" android:layout_height = "fill_parent" android:text="Previous Menu"/> </LinearLayout> What am I missing here to be able to intercept clicks on the Listview? Thanks

  • MSVC++ 6.0: Fatal error C1509 "Too many exception handler states in function"

    - by sep332
    I'm working on a project that uses a lot of generated files for a GUI. After some recent updates, I get this error. If I remove some controls (the new ones or some old ones, doesn't seem to matter which), the error goes away. I've temporarily worked around the problem, but I'd like a more permanent solution. I've seen mentioned on the web that there's a fix for this in VS.Net 2003, but I can't find anything for 6.0. Does anyone know of a hotfix or service pack that fixes this?

  • [java] Threading socket handler for two sided communication in tcp port

    - by raven
    I want to make a chat which will be programed in java. one computer will host the server and the other one will initiate the socket [tcp port]. now from what I read there should be a loop that will constantly read the socket which means it will make the code stuck. I have a button that is 'actionperformed' on mouse release, I want to know if it will work along with the loops that constantly reads the socket so that it will also send the infromation I wrote. If I must thread it, I want to know if the run() method must be void because if I thread it it will mean creating a new class, and the whole GUI is one big class which includes a text area, and it's private. also how can I extract the information from the socket directly to the text area? lets say the textarea variable is called "chatOutput". thx :)

  • Using document.write in event handler?

    I am experimenting with HTML and JavaScript. The following code should print something when entering a keystroke in a textbox: <html> <body> <input type="text" id="commandInput" name="command" size="50" /> <script type="text/javascript"> var commandInput = document.getElementById("commandInput"); commandInput.onkeydown = function (evt) { document.writeln("Test"); }; </script> </body> </html> For some reason the textbox disappears when entering a keystroke, leaving nothing but a white page. Any ideas why this is happening?
