  • Catching the Facebook Login Event to change the HTML of the parent page

    - by Arkid
    I am trying to create Facebook based login using Javascript. Once a person clicks a button he should get a div replaced by another div, if he is logged in to Facebook. However, if he is not logged in to Facebook he is asked his Facebook credentials and he logs in. However, we need the user to click the button once more for the div replacement to happen in this case. I want to know if there is a way in which I can catch the Facebook login event and change the div? Is polling a way or there is some other way out. I want to use only Javascript.

  • C# Event Handlers automatically created by WinForms Designer

    - by RHaguiuda
    Just moved from VB.NET to C#. In VB to connect and Event Handler to a Sub we use the Handles clause. From what it seems, this do not exist in C#. After creating a simple application with a button I realize that Window Forms Designer automatically created an EventHandler to my button1_Click function (after I double clicked it), in Form1.Designer.cs with this code: this.button1.Click += new System.EventHandler(this.button1_Click); But, in VB, the WinForms Designer create the Handles clause in my class, in the function header. So, C# create the default EventHandler in designer file, while VB creates in main class with control resides. Is this correct? Am I missing something here?

  • Discrete event simulation framework for .NET

    - by Kuba
    Does anyone have an experience with some discrete event simulation library that could be used in .NET (C#)? Despite the basic functionality for queing events and dispatching them, it would be fine to have some non-deterministic behavior (e.g. failures simulation). I have some tips and I am even considering to write my own, but first, I would like to collect some recomendations. Thanks. Additional info: i'm not looking explicitly for free product, however, the prize matters :) Just to precise the field i need to map, here is the example of a product: http://www.holushko.com/index.html

  • jQuery event binding does not work properly or i can't make it properly working

    - by Saiful
    HTML: <input id="email" name="email" type=text /> <input id="password name="password" type="password" /> JavaScript: var fields = ["email","password"]; for (var i in fields) { var field = $("#"+fields[i]); field.bind({ focus: function() { field.css("border-color","#f00"); }, blur: function() { field.css("border-color","#000"); } }); } My desire action will be as follows: When I place cursor on any of the above fields the input field's border will be red. When I take away the cursor from the field it's border will be black. But the event is occurs only for the password filed whether I place and take away cursor form any of the above fields.

  • How to implement event notification mechanism in AIR

    - by nxhoaf
    Do you know how to implement event notification mechanism in AIR ? For simplicity, consider an example: I want to build two applications: "television" and "remote". Among them, television is implemented using AIR. For the "television" I want to use my remote to send message to the television. How must I do to implement "television" in such way that, it runs in waiting mode and whenever it receives a message from "remote", it will process the message and make a suitable action (i.e. change channel, increase volume...). Thank you in advance.

  • jQuery resize event for div children

    - by Frank Michael Kraft
    $("div.content-left > *, div.content-main > *" ).live('resize',function(){alert("Size changed")}); does not work, because the resize event only applies to window resizes. But in my case the divs change size late, because the content is loaded late by an ajax request - or by clicking a panel menu. I definatley need to avoid to register on all individual events of the children (ajax, click), because that can be very many different events and then it is not maintainable.

  • What is the correlation between programming language and experience/skills of their users?

    - by Petr Pudlák
    I'm sure there is such a correlation, because experience and skill leads good programmers to picking languages that are better for them, in which they're more productive, and working in a language forms how programmers think and influences their methods and skills. Is there any research or some statistical data of this phenomenon? Perhaps this is not a purely academic question. For example, if someone is starting a new project, it could be worth considering a language (among other criteria of course) for which there is a higher chance of finding or attracting experienced programmers. Update: Please don't fixate on the last paragraph. It's not my intention to choose a language based on this criterion, and I know there are other far more important ones. My interested is mostly academic. It comes from the (subjective) observation and I wonder if someone has researched it a bit. Also, I'm talking about a correlation, not about a rule. Sure there are both great and terrible programmers in every language. Just that in general it seems to me there is a correlation.

  • How can calculus and linear algebra be useful to a system programmer?

    - by Victor
    I found a website saying that calculus and linear algebra are necessary for System Programming. System Programming, as far as I know, is about osdev, drivers, utilities and so on. I just can't figure out how calculus and linear algebra can be helpful on that. I know that calculus has several applications in science, but in this particular field of programming I just can't imagine how calculus can be so important. The information was on this site: http://www.wikihow.com/Become-a-Programmer Edit: Some answers here are explaining about algorithm complexity and optimization. When I made this question I was trying to be more specific about the area of System's Programming. Algorithm complexity and optimization can be applied to any area of programming not just System's Programming. That may be why I wasn't able to came up with such thinking at the time of the question.

  • Reformatting a table based photo gallery to a UL based gallery

    - by mmsa
    I have the following code: var table = $('.photogalleryTable').before('<ul class="photogallery"></ul>') table.find('td a').wrap('<li>').parent().appendTo('ul.photogallery'); table.remove(); This code finds a table with a list of photos and re-codes it to use a unordered list instead. The script works perfectly except for one issue. If there are 2 galleries on a page, the script will grab all of the images and reformat them into one list. Because the CMS I'm using tags each gallery table with .photogalleryTable, I'm not sure how to keep the script from touching the other galleries. What I would like to have happen is have the script re-format the first instance and then move on to the next instance, keeping the list of photos separate Is that possible?

  • Perl: Event-driven Programming

    - by Shiftbit
    Is there any POSIX signals that I could utilize in my perl program to create event-driven programming? Currently I have multi-process program that is able to cross communicate but my parent thread is only able to listen to listen at one child at a time. foreach (@threads) { sysread(${$_}{'read'}, my $line, 100); chomp($line); print "Parent hears: $line\n"; } The problem is that the parent sits in a continual wait state until it receives it a signal from the first child before it can continue on. I am relying on 'pipe' for my intercommunication. My current solution is very similar to: http://stackoverflow.com/questions/2558098/how-can-i-use-pipe-to-facilitate-interprocess-communication-in-perl If possible I would like to rely on a $SIG{...} event or any non-CPAN solution.

  • Event Handling for MFC Dialog

    - by Maksud
    This is my second question of the day, pardon me. I am writing a wrapper library to communicate with a scanner device. The source code was in C++ MFC. I am converting it to a plain Dll which will be invoked from C#. So, I am using DllImport in C# to call the wrapper library. Now I am provided with MFC code and the library is a ActiveX Object, at least I think so. class CDpocx : public CWnd { } So in my wrapper library I will have an instance of CDpocx and will call it via C# P/Invoke. But the problem is CDpocx also throws some events which I need to catch. In traditional app, I would just attach an function with it. But How would I attach the events on non MFC class. I have seen something like: BEGIN_EVENTSINK_MAP(CVC60Dlg, CDialog) //{{AFX_EVENTSINK_MAP(CVC60Dlg) ON_EVENT(CVC60Dlg, IDC_DPOCXCTRL1, 1 , OnReadyDpocxctrl1, VTS_NONE) //}}AFX_EVENTSINK_MAP END_EVENTSINK_MAP() OnReadyDpocxctrl1 is the function that handles 1 (Ready) event. How can I gain simmilar function in non MFC class. Regards, Maksud

  • What is the harm in giving developers read access to application server application event logs?

    - by Jim Anderson
    I am a developer working on an ASP.NET application. The application writes logging messages to the Windows event log - a custom application log just for this application. However, I do not have any access to testing or staging web/application servers. I thought an admin could just give me read access to this event log to help in debugging problems (currently a service that is working in dev is not working in test environment and I have no idea why) but that is against my client's (I'm a consultant) policy. I feel silly to keep asking an admin to look at the event log for me. What is the harm in giving developers read access to application server application event logs? Is there a different method of application logging that sysadmins prefer programmers use? Surely, admins don't want to be fetching logging messages for developers all the time.

  • How to write program to do file transfer based on based omniORBpy

    - by cofthew7
    I'm now writing a Corba project to do file transfering between client and server. But I face trouble when I want to upload file from the client to the server. The IDL I defined is: interface SecretMessage { string send_file(in string file_name, in string file_obj); }; And I implemented the uploading function in the client code: f = open('SB.docx', 'rb') data = '' for piece in read_in_chunks(f): data += piece result = mo.send_file('2.docx', data) If the file is a plain txt file, there is no problem. But if the file is a, like jpg, doc, or others except txt, then it does work. It gives me the error: omniORB.CORBA.BAD_PARAM: CORBA.BAD_PARAM(omniORB.BAD_PARAM_WrongPythonType, CORBA.COMPLETED_NO) Where is the problem?

  • Programming for a 32-bit environment vs programming for a 64-bit environment / Build configurations

    - by Russel
    I was looking at some same code (a sample MS Visual Studio C++ project) recently with multiple build configurations (Release/Debug, Win32/x64). My question: What is the difference? I guess I understand Release/Debug (Release = finalized version of project, Debug = version used to run in debugger), but what things need to be considered when building different versions for Win32/x64 platforms? Is there any coding differences, or does this just affect how that same code is ultimately built into machine code? I know there are different library files depending on whether you're using a 32-bit or 64-bit system as well... Are all of these differences again just machine code? Would a 32-bit library file and its corresponding 64-bit library file be two files with exactly the same functions build from the same source code originally, and only differing in their machine code implementation? Thanks! --Russel

  • ctrl+click or shift+click not always firing the onclick event

    - by Erik
    Hi, I recently discovered that different browsers handle the onclick event differently when the control of shift key is pressed. Same thing for following links with the middle mouse button. <a href="http://www.example.com/" onclick="alert('onclick');">go to example.com</a> Onclick browser support table Mouse Keyboard Chrome Firefox Safari Opera IE5.5 IE6 IE7 IE8 IE9 Left None yes yes yes yes yes yes yes yes yes Left Ctrl yes yes yes yes ? yes no no ? Left Shift yes yes yes yes ? yes yes yes ? Middle None yes no yes no ? N/A no no ? Can someone please fill in the question marks for me? Also; I'm wondering if the behaviour differs for each version of Chrome, Firefox, Safari and Opera. Finding a logical pattern in this behaviour would be even nicer, but I don't think there is :). Thanks a lot.

  • C++ Storing variables and inheritance

    - by Kaa
    Hello Everyone, Here is my situation: I have an event driven system, where all my handlers are derived from IHandler class, and implement an onEvent(const Event &event) method. Now, Event is a base class for all events and contains only the enumerated event type. All actual events are derived from it, including the EventKey event, which has 2 fields: (uchar) keyCode and (bool)isDown. Here's the interesting part: I generate an EventKey event using the following syntax: Event evt = EventKey(15, true); and I ship it to the handlers: EventDispatch::sendEvent(evt); // void EventDispatch::sendEvent(const Event &event); (EventDispatch contains a linked list of IHandlers and calls their onEvent(const Event &event) method with the parameter containing the sent event. Now the actual question: Say I want my handlers to poll the events in a queue of type Event, how do I do that? x Dynamic pointers with reference counting sound like too big of a solution. x Making copies is more difficult than it sounds, since I'm only receiving a reference to a base type, therefore each time I would need to check the type of event, upcast to EventKey and then make a copy to store in a queue. Sounds like the only solution - but is unpleasant since I would need to know every single type of event and would have to check that for every event received - sounds like a bad plan. x I could allocate the events dynamically and then send around pointers to those events, enqueue them in the array if wanted - but other than having reference counting - how would I be able to keep track of that memory? Do you know any way to implement a very light reference counter that wouldn't interfere with the user? What do you think would be a good solution to this design? I thank everyone in advance for your time. Sincerely, Kaa

  • Calendar gets saved successfully.but edit event force close error

    I am trying to add calendar events with my applicatiom. Event gets saved successfully. However when i try to edit that event in Calendar. I get Force Close error. String calId = ""; Cursor userCursor =getContentResolver().query(Uri.parse(content://com.android.calendar/calendars),null, null, null, null); if(userCursor.getCount() > 0){ userCursor.moveToFirst(); calId = userCursor.getString(userCursor.getColumnIndex("_id")); } ContentValues event = new ContentValues(); event.put("title", "title"); event.put("description", "description"); event.put("eventLocation", "Event Location"); event.put("allDay", 0); event.put("hasAlarm",0); event.put("calendar_id",calId); Calendar mCalendar = Calendar.getInstance(); mCalendar.set(2012, 2, 27,7,00,00); long start = mCalendar.getTimeInMillis(); mCalendar.set(2012, 2, 27,8,00,00); long end = mCalendar.getTimeInMillis(); event.put("dtstart", start); event.put("dtend", end); Uri newEvent = Uri.parse(content://com.android.calendar/events); getContentResolver().insert(newEvent, event); ContentValues values = new ContentValues(); userCursor.close(); But when I change event.put("allDay", 0); to event.put("allDay", 1); Event gets saved successfully and gets edited successfully. How do I fix it? Using 2.3.5 device. Appreciate any help. thanks.

  • Implementing crossover in genetic programming

    - by Name
    Hi, I'm writing a genetic programming (GP) system (in C but that's a minor detail). I've read a lot of the literature (Koza, Poli, Langdon, Banzhaf, Brameier, et al) but there are some implementation details I've never seen explained. For example: I'm using a steady state population rather than a generational approach, primarily to use all of the computer's memory rather than reserve half for the interim population. Q1. In GP, as opposed to GA, when you perform crossover you select two parents but do you create one child or two, or is that a free choice you have? Q2. In steady state GP, as opposed to a generational system, what members of the population do the children created by crossover replace? This is what I haven't seen discussed. Is it the two parents, or is it two other, randomly-selected members? I can understand if it's the latter, and that you might use negative tournament selection to choose members to replace, but would that not create premature convergence? (After a crossover event the population contains the two original parents plus two children of those parents, and two other random members get removed. Elitism is inherent.) Q3. Is there a Web forum or mailing list focused on GP? Oddly I haven't found one. Yahoo's GP group is used almost exclusively for announcements, the Poli/Langdon Field Guide forum is almost silent, and GP discussions on general/game programming sites like gamedev.net are very basic. Thanks for any help you can provide!

  • Experience with Take home Programming Test for Interviews

    - by Alan
    Okay this is not "programming" related per-se, but it is a situation that I believe the SO audience would be more familiar with, than say an ask.yahoo.com audience, so please forgive me. I had a phone screen the other day with a company that I really want to work for. It went pretty well, based on cues from the HR person, such as "Next step we're going to send you a programming test," and "Well, before I get ahead of myself, do you want to continue the interviewing process." and "We'll send out the test later this afternoon. It doesn't sound like you'll have trouble with it, but I want to be honest we do have a high failure rate on it." The questions asked weren't technical, just going down my resume, and talking about the work I've done, and how it relates to the position. Nothing I couldn't talk through. This was last Thursday. It's now Tuesday, and haven't received the test yet. I sent a follow up email yesterday to the lady who interviewed me, but haven't gotten a response. Anyone had a similar experience? Am I reading too much into this? Or was I off the mark by thinking I had moved on to the next step in the interview process. Since this is a company I really want to work for, I'm driving myself insane enumerating all the various what-if scenarios.

  • Passing additional parameters to JQuery bind event function

    To pass the additional parameter to the event function pass an array of key value, as the second parameter to the bind event bind('click', { message: time }, onClick); e.g { message: time } and access it in the function using event(function parameter).data.message(key)   <div id="div1" style="border: 1px solid black; width: 100px; height: 100px">click me</div> <script type="text/javascript"> function onClick(event) { alert(event.data.message); } var time = "loaded at:" + new Date().toString(); $("div.#div1").bind('click', { message: time }, onClick); </script>

  • Ways of Gathering Event Information From the Internet

    - by Ciwan
    What are the best ways of gathering information on events (any type) from the internet ? Keeping in mind that different websites will present information in different ways. I was thinking 'smart' web crawlers, but that can turn out to be extremely challenging, simply because of the hugely varied ways that different sites present their information. Then I was thinking of sifting through the official twitter feeds of organisations, people with knowledge of events .. etc and look for the event hash tag, grab the tweet and dissect it to grab the relevant information about the event. Information I am interested in gathering is: Date and Time of Event, Address where Event is being held, and any Celebrities (or any famous people) attending the event (if any). The reason to ask here is my hope that experienced folk will open my eyes to things I've missed, which I am sure I have.

  • One True Event Loop

    - by CyberShadow
    Simple programs that collect data from only one system need only one event loop. For example, Windows applications have the message loop, POSIX network programs usually have a select/epoll/etc. loop at their core, pure SDL games use SDL's event loop. But what if you need to collect events from several subsystems? Such as an SDL game which doesn't use SDL_net for networking. I can think of several solutions: Polling (ugh) Put each event loop in its own thread, and: Send messages to the main thread, which collects and processes the events, or Place the event-processing code of each thread in a critical section, so that the threads can wait for events asynchronously but process them synchronously Choose one subsystem for the main event loop, and pass events from other subsystems via that subsystem as custom messages (for example, the Windows message loop and custom messages, or a socket select() loop and passing events via a loopback connection). Option 2.1 is more interesting on platforms where message-passing is a well-developed threading primitive (e.g. in the D programming language), but 2.2 looks like the best option to me.
