  • jQuery - Increase the value of a counter when a button is clicked

    - by Taimur
    Hi, I'm making a system where a user clicks a button and their score increases. There is a counter which I would like to increase the value of using jQuery (so that the page does not need to refresh) when the button is clicked. How would I go about this? <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.3.min.js"></script> <script type="text/javascript"> $("#update").click(function() { $("#counter")++; } </script> #update is the button, #counter is the counter. In php, ++ increases something's value. What's the jQuery equivalent? Also, when the button is clicked, it needs to send a request which updates the score value in a mysql database as well, without the page refreshing. Does anyone know how I would do that? Thanks a lot UPDATE: I've tried a few of the methods below, but nothing seems to work! Do I need to change anything else for it to work? I've created a test page for it: <html> <body> <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.3.min.js"></script> <script type="text/javascript"> var count = 0; $("#update").click(function() { count++; $("#counter").html("My current count is: "+count); } </script> <button id="update" type="button">Button</button> <div id="counter">1</div> </body> </htlm>

  • What are the benefits of the PHP the different PHP compression libraries?

    - by Christopher W. Allen-Poole
    I've been looking into ways to compress PHP libraries, and I've found several libraries which might be useful, but I really don't know much about them. I've specifically been reading about bcompiler and PHAR libraries. Is there any performance benefit in either of these? Are there any "gotchas" I need to watch out for? What are the relative benefits? Do either of them add to/detract from performance? I'm also interested in learning of other libs which might be out there which are not obvious in the documentation? As an aside, does anyone happen to know whether these work more like zip files which just happen to have the code in there, or if they operate more like Python's pre-compiling which actually runs a pseudo-compiler? ======================= EDIT ======================= I've been asked, "What are you trying to accomplish?" Well, I suppose the answer is that this is all hypothetical. It is a combination of these: What if my pet project becomes the most popular web project on earth and I want to distribute it quickly and easily? (hay, a man can dream, right?) It also seems if using PHAR can be done easily, it would be the best way to create a subversion snapshot. Python has this really cool pre-compiling policy, I wonder if PHP has something like that? These libraries seem to do something similar. Will they do that? Hey, these libraries seem pretty neat, but I'd like clarification on the differences as they seem to do the same thing

  • How do I stop the m2eclipse plugin interfering with command line mvn builds?

    - by locka
    I use the m2eclipse plugin in Eclipse so that I can import a Maven project. The plugin reads the pom.xml and sorts out the dependencies in the projects in an Eclipse friendly way so I'm not looking at a sea of broken references and errors. I use Eclipse for code development however I usually build the projects from the command line, e.g. "mvn clean install". Unfortunately when I do this, m2eclipse detects disk activity and attempts to rebuild the workspace. This interferes with the command line build and sometimes results in a race condition. For example the command line might be in its clean phase but fails because it tries to delete a file or directory which is locked during the workspace rebuild. Aside from that workspace rebuilding is incredibly slow, and between failed builds and wasted CPU my build process is 2-3x longer than it should be. It isn't an option to not use Eclipse (e.g. to use Netbeans), or to disable m2eclipse. It is a useful plugin except for this behaviour. So my question is, how do I stop m2eclipse from rebuilding the workspace all the time? Can I invoke a manual refresh and otherwise disable this behaviour?

  • XmlHttpRequest in a bookmarklet returns empty responseText on GET?

    - by David Eyk
    I'm trying to build a javascript bookmarklet for a special URL shortening service we've built at http://esv.to for shortening scripture references (i.e. "Matthew 5" becomes "http://esv.to/Mt5". The bookmarklet is supposed to do a GET request to http://api.esv.to/Matthew+5, which returns a text/plain response of http://esv.to/Mt5. The code for the bookmarklet itself looks like this (expanded for readability): var body = document.getElementsByTagName('body')[0], script = document.createElement('script'); script.type = 'text/javascript'; script.src = 'http://esv.to/media/js/bookmarklet.js'; body.appendChild(script); void(0); The code from http://esv.to/media/js/bookmarklet.js looks like this: (function() { function shorten(ref, callback) { var url = "http://esv.to/api/" + escape(ref); var req = new XMLHttpRequest(); req.onreadystatechange = function shortenIt() { if ( this.readyState == 4 && this.status == 200 ) { callback(req.responseText); }; }; req.open( "GET", url ); req.send(); }; function doBookmarklet() { var ref = prompt("Enter a scripture reference or keyword search to link to:", "") shorten(ref, function (short) { prompt("Here is your shortened ESV URL:", short); }); }; doBookmarklet(); })(); When called from http://esv.to itself, the bookmarklet works correctly. But when used on another page, it does not. The strange thing is, when I watch the request from Firebug, the response is 200 OK, the browser downloads 17 bytes (the length of the returned string), but the response body is empty! No error is thrown, just an empty responseText on the XmlHttpRequest object. Now, according to http://stackoverflow.com/questions/664689/ajax-call-from-bookmarklet, GET shouldn't violate the same origin policy. Is this a bug? Is there a workaround?

  • ASP.NET MVC: Returning a view with querystring in tact

    - by ajbeaven
    I'm creating a messaging web app in ASP.NET and are having some problems when displaying an error message to the user if they go to send a message and there is something wrong. A user can look through profiles of people and then click, 'send a message'. The following action is called (url is /message/create?to=username) and shows them a page where they can enter their message and send it: public ActionResult Create(string to) { ViewData["recipientUsername"] = to; return View(); } On the page that is displayed, the username is entered in to a hidden input field. When the user clicks 'send': [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(string message, string to) { try { //do message stuff that errors out } catch { ModelState.AddModelErrors(message.GetRuleViolations()); //adding errors to modelstate } return View(); } So now the error message is displayed to the user fine, however the url is changed in that it no longer has the querystring (/message/create). Again, this would be fine except that when the user clicks the refresh button, the page errors out as the Create action no longer has the 'to' parameter. So I'm guessing that I need to maintain my querystring somehow. Is there any way to do this or do I need to use a different method altogether?

  • Problems with "global" exception handlers for unhandled exceptions in multithreaded WPF

    - by JustABill
    I have a program that, among other things, needs to be able to refresh the contents of a directory when the user tells it to. The actual task doesn't really matter, but this is the simplest way of causing this problem to occur that I know of. If I tell it to open a directory that doesn't exist, I get the "unhandled exception" dialog in VS with a stack trace of, from outer to inner: [External code] Textbox PreviewKeyUp event [External code] ClassA's path property being set ClassA's internal path update function being called A call to the INotifyPropertyChanged event [External code] A call to the getter for ClassB's list of children A call to ClassB's internal directory list function And then it fails inside this internal function. I have the following in my App.xaml.cs: private void Application_Startup(object sender, StartupEventArgs e) { AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); Application.Current.Dispatcher.UnhandledException += new System.Windows.Threading.DispatcherUnhandledExceptionEventHandler(Dispatcher_UnhandledException); } But neither of their exception handlers are being called. If I run this program from outside VS, I don't get notified of an exception at all, it just breaks because of the invalid input. And yes, the Application_Startup event is being called. How can I properly "trap" this exception so I can provide a friendly error message and kill the program?

  • What is the best way to auto-generate INSERT statements for a SQL Server table?

    - by JosephStyons
    We are writing a new application, and while testing, we will need a bunch of dummy data. I've added that data by using MS Access to dump excel files into the relevant tables. Every so often, we want to "refresh" the relevant tables, which means dropping them all, re-creating them, and running a saved MS Access append query. The first part (dropping & re-creating) is an easy sql script, but the last part makes me cringe. I want a single setup script that has a bunch of INSERTs to regenerate the dummy data. I have the data in the tables now. What is the best way to automatically generate a big list of INSERT statements from that dataset? I'm thinking of something like in TOAD (for Oracle) where you can right-click on a grid and click Save As-Insert Statements, and it will just dump a big sql script wherever you want. The only way I can think of doing it is to save the table to an excel sheet and then write an excel formula to create an INSERT for every row, which is surely not the best way. I'm using the 2008 Management Studio to connect to a SQL Server 2005 database.

  • Raw types and subtyping

    - by Dmitrii
    We have generic class SomeClass<T>{ } We can write the line: SomeClass s= new SomeClass<String>(); It's ok, because raw type is supertype for generic type. But SomeClass<String> s= new SomeClass(); is correct to. Why is it correct? I thought that type erasure was before type checking, but it's wrong. From Hacker's Guide to Javac When the Java compiler is invoked with default compile policy it performs the following passes: parse: Reads a set of *.java source files and maps the resulting token sequence into AST-Nodes. enter: Enters symbols for the definitions into the symbol table. process annotations: If Requested, processes annotations found in the specified compilation units. attribute: Attributes the Syntax trees. This step includes name resolution, type checking and constant folding. flow: Performs data ow analysis on the trees from the previous step. This includes checks for assignments and reachability. desugar: Rewrites the AST and translates away some syntactic sugar. generate: Generates Source Files or Class Files. Generic is syntax sugar, hence type erasure invoked at 6 pass, after type checking, which invoked at 4 pass. I'm confused.

  • DataGridView not displaying a row after it is created

    - by joslinm
    Hi, I'm using Visual Studio 10 and I just created a Database using SQL Server CE. Within it, I made a table CSLDataTable and that automatically created a CSLDataSet & CSLDataTableTableAdapter. The three variables were automatically created in my MainWindow.cs class: cSLDataSet cSLDataTableTableAdapter cSLDataTableBindingSource I have added a DataGridView in my Form called dataGridView and datasource cSLDataTableBindingSource. In my MainWindow(), I tried adding a row as a test: public MainWindow() { InitializeComponent(); CSLDataSet.CSLDataTableRow row = cSLDataSet.CSLDataTable.NewCSLDataTableRow(); row.File_ = "file"; row.Artist = "artist11"; row.Album = "album"; row.Save_Structure = "save"; row.Sent = false; row.Error = true; row.Release_Format = "release"; row.Bit_Rate = "bitrate.."; row.Year = "year"; row.Physical_Format = "format"; row.Bit_Format = "bitformat"; row.File_Path = "File!!path"; row.Site_Origin = "what"; cSLDataSet.CSLDataTable.Rows.Add(row); cSLDataSet.AcceptChanges(); cSLDataTableTableAdapter.Fill(cSLDataSet.CSLDataTable); cSLDataTableTableAdapter.Update(cSLDataSet); dataGridView.Refresh(); dataGridView.Update(); } In regards to the DataSet methods I tried calling, I had been trying to find a "correct" way to interact with the adapter, dataset, and datatable to successfully show the row, but to no avail. I'm rather new to using SQL Server CE Database, and read a lot of the MSDN sites & thought I was on the right track, but I've had no luck. The DataGridView shows the headers correctly, but that new row does not show up.

  • C++ : Avoid lot of boolean variable for multiple verification conditions in trading app

    - by Naveen
    Hi i am a junior dev in trading app... we have a order refresh verification unit. It has to verify order confirmation from exchange. We send a bunch of different request in bulk ( NEW, MODIFY, CANCEL ) to exchange... Verification has to happen for max N times with each T intervals for all orders. if verification successful for all the order before N retry then fine.. otherwise we need to indicate as verification unsuccessfull. i hv done a basic coding done in very urgent like below for( N times ) { for_each ( sent_request_order ) // SENT { 1) get all the refreshed order from DB or shared mem i.e REFRESHED 2) find current sent order in REFRESHED if( not_found ) not refreshed from exchange, continue to next order if( found ) case NEW : //check for new status, mark verification done case MODIFY : //check for modified status.. //if not mark pending, go to next order, //revisit the same after T time case CANCEL : //check for cancelled status.. //if not mark pending, go to next order, //revisit the same after T time } if( all_verified ) exit from verification. wait ( T sec ) } order_verification_pending, order_verification_done, order_visited, order_not_visited, all_verified, all_not_verified ... lot of boolean flags used for indication.. is there any better approach for doing this.... splitting responsibilities across the classes......???? i know this is not a general question.... but still flags are making me tidious to handle...

  • Core data migration failing with "Can't find model for source store" but managedObjectModel for source is present

    - by Ira Cooke
    I have a cocoa application using core-data, which is now at the 4th version of its managed object model. My managed object model contains abstract entities but so far I have managed to get migration working by creating appropriate mapping models and creating my persistent store using addPersistentStoreWithType:configuration:options:error and with the NSMigratePersistentStoresAutomaticallyOption set to YES. NSDictionary *optionsDictionary = [NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES] forKey:NSMigratePersistentStoresAutomaticallyOption]; NSURL *url = [NSURL fileURLWithPath: [applicationSupportFolder stringByAppendingPathComponent: @"MyApp.xml"]]; NSError *error=nil; [theCoordinator addPersistentStoreWithType:NSXMLStoreType configuration:nil URL:url options:optionsDictionary error:&error] This works fine when I migrate from model version 3 to 4, which is a migration that involves adding attributes to several entities. Now when I try to add a new model version (version 5), the call to addPersistentStoreWithType returns nil and the error remains empty. The migration from 4 to 5 involves adding a single attribute. I am struggling to debug the problem and have checked all the following; The source database is in fact at version 4 and the persistentStoreCoordinator's managed object model is at version 5. The 4-5 mapping model as well as managed object models for versions 4 and 5 are present in the resources folder of my built application. I've tried various model upgrade paths. Strangely I find that upgrading from an early version 3 - 5 works .. but upgrading from 4 - 5 fails. I've tried adding a custom entity migration policy for migration of the entity whose attributes are changing ... in this case I overrode the method beginEntityMapping:manager:error: . Interestingly this method does get called when migration works (ie when I migrate from 3 to 4, or from 3 to 5 ), but it does not get called in the case that fails ( 4 to 5 ). I'm pretty much at a loss as to where to proceed. Any ideas to help debug this problem would be much appreciated.

  • Iframe in Tab Madness!

    - by 404error
    I've searched all over and have found possible solutions but they don't quite work how i need them to. I am really new to jQuery but I'm trying :-) I have an iframe that sits in a Tab ( Tabs powered by jQuery) In the third tab sits an iframe that holds a slideshow My problem: When I click on the third tab which houses the iframe all the controls appear, the carousel seems to be working, but ...no pictures!!! Firefox helped me find what fixes the problem, now i just need to find a way to do fix it. In Firefox when i right click on the iframe and go to This frame - Reload Frame VOILA! Pictures are back! Question: Is it possible with jQuery to tell when the third tab is selected and to refresh a div which contains the iframe when that third tab is selected? Tab Code: <script type="text/javascript" charset="utf-8"> $(function () { var tabContainers = $('div.tabs > div'); tabContainers.hide().filter(':first').show(); $('div.tabs ul.tabNavigation a').click(function () { tabContainers.hide(); tabContainers.filter(this.hash).show(); $('div.tabs ul.tabNavigation a').removeClass('selected'); $(this).addClass('selected'); return false; }).filter(':first').click(); }); </script> Test page can be found here: http://artitechture.com/blah/tabs.html Any help would be appreciated...I want to learn!

  • How to parse rss from a php page, using jQuery/jFeed?

    - by ricebowl
    I'm trying to fumble my way through parsing rss sensibly, using jQuery and jFeed. Because of the same origin policy I'm pulling the BBC's health news feed into a local page (http://www.davidrhysthomas.co.uk/play/proxy.php). Originally this was just the same proxy.php script as available in the jFeed download package, but due to my host's disabling allow_url_fopen() I've amended the php to the following: $url = "http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/health/rss.xml"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $data = curl_exec($ch); echo "$data"; curl_close($ch); Which seems to generate the same/comparable contents as the original fopen on my local machine. Now that seems to be working, I'm looking at setting the jFeed script up to work with the page and, to my embarrassment, don't see how. I understand that, at the least, this should work: jQuery.getFeed({ url: 'http://www.davidrhysthomas.co.uk/play/proxy.php', success: function(feed) { alert(feed.title); } }); ...but, as I'm sure you anticipate, it doesn't. What non-output there is, is available for your perusal here: http://www.davidrhysthomas.co.uk/play/exampleTest.html. And I honestly don't have a clue what to do about it. If anyone could offer some pointers, tips, hints, or, at a pinch, a quick slap around the cheeks and a 'pull yourself together!' it'd be much appreciated... Thanks in advance =)

  • Ajax UpdatePanels scroll on partial page update.

    - by George
    I set the AutoPostback property of a textbox to True so I can process the TextChanged event on the server and, based on what they typed in the textbox, appropriately display a message in an update panel. The problem is, when the partial screen refresh is performed, no control on the screen has focus. 99% of the time, when the text in the textbox is changed, it is because the user has tabbed forward, and so, to limit the disruption in the lost of focus, I perform a "Focus" call on teh next control in the tab sequence. For the most part, this works OK, but of course, is disputive if the user is tabbing in the reverse order or has used the mouse to set the focus to another control. In these situations, the focus would be set to the next control even though the user was trying to set focus elsewhere. OK, that sucks. Now what I consider the bigger problem with calling the focus method on the server: In IE, it works OK, but in Mozilla Firefox and Chrome, setting the focus causes a repositioning of the scroll bar, even though none is necessary because the control is already in view. I realize that I could switch to doing AJAX web service calls, but these darn Updae Panels are so convenient if used in moderation. is there anyway to use updatepanels and not have these focus/scroll issues?

  • Jquery .val() for input only works once.

    - by Bolt_Head
    I'm trying to create a chat box for my game. The user type's their chat into the input:text feild and by ither pressing Enter or clicking the button submits the chat text. This all works, however for some reason after the first time a user submits a chat message it fails to get the text from the input field. Here is my code. $(document).ready(function() { $("#chatEnter").live('click',function(){ var chat = $('#chatText').val(); sendChat(chat); }); }); $(document).ready(function() { $("#chatText").keypress(function(e){ if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { var chat = $('#chatText').val(); sendChat(chat); return false; } else return true; }); }); function sendChat(chat) { alert(chat); //temp test alert $.getJSON("includes/boardUpdate.php",{chat: chat, bid: bid}); $('#chatText').val(""); } It doesn't matter if i first submit a text by clicking the button or pressing enter, all future attempts submit blank entrys until I refresh the page. Edit: I've tried it with and without the line to clear the text box, same results both ways. Your help is appreciated.

  • Runtime Exception when using Custom Healthmonitoring event in medium trust

    Hi, I'm using custom healthmonitoring events in ASP.NET We recently moved to a new server with default High Trust Permissions. Literature says that healthmonitoring and custom events should work under Medium or higher trust (http://msdn.microsoft.com/en-us/library/bb398933.aspx). Problem is it doesn't. In less than high trust I get a SecurityException saying The application attempted to perform an operation not allowed by the security policy It works in Full trust or when I remove the inheritance of System.Web.Management.WebErrorEvent.

  • New TabItem Content ActualHeight crashes Xaml Window

    - by Jack Navarro
    I am able to create new TabItems with Content dynamically to a new window by streaming the Xaml with XamlReader: NewWindow newWindow = new NewWindow(); newWindow.Show(); TabControl myTabCntrol = newWindow.FindName("GBtabControl") as TabControl; StringReader stringReader = new StringReader(XamlGrid); XmlReader xmlReader = XmlReader.Create(stringReader); TabItem myTabItem = new TabItem(); myTabItem.Header = qDealName; myTabItem.Content = (UIElement)XamlReader.Load(xmlReader); myTabCntrol.Items.Add(myTabItem); This works fine. It displays a new grid wrapped in a scrollviewer. The problem is access the TabItem content from the newWindow. TabItem ti = GBtabControl.SelectedItem as TabItem; string scrollvwnm = "scrollViewer" + ti.Header.ToString(); MessageBox.Show(ti.ActualHeight.ToString()); // returns 21.5 ScrollViewer scrlvwr = this.FindName(scrollvwnm) as ScrollViewer; MessageBox.Show(scrollvwnm); // Displays name double checked for accuracy MessageBox.Show(scrlvwr.ActualHeight.ToString()); //Crashes ScrollViewer scrlvwr = ti.FindName(scrollvwnm) as ScrollViewer; MessageBox.Show(scrollvwnm); // Displays name double checked for accuracy MessageBox.Show(scrlvwr.ActualHeight.ToString()); //Also Crashes Is there a method to refresh UI in XAML so the new window is able to access the newly loaded tab item content?

  • Creating a smart text generator

    - by royrules22
    I'm doing this for fun (or as 4chan says "for teh lolz") and if I learn something on the way all the better. I took an AI course almost 2 years ago now and I really enjoyed it but I managed to forget everything so this is a way to refresh that. Anyway I want to be able to generate text given a set of inputs. Basically this will read forum inputs (or maybe Twitter tweets) and then generate a comment based on the learning. Now the simplest way would be to use a Markov Chain Text Generator but I want something a little bit more complex than that as the MKC basically only learns by word order (which word is more likely to appear after word x given the input text). I'm trying to see if there's something I can do to make it a little bit more smarter. For example I want it to do something like this: Learn from a large selection of posts in a message board but don't weight it too much For each post: Learn from the other comments in that post and weigh these inputs higher Generate comment and post See what other users' reaction to your post was. If good weigh it positively so you make more posts that are similar to the one made, and vice versa if negative. It's the weighing and learning from mistakes part that I'm not sure how to implement. I thought about Artificial Neural Networks (mainly because I remember enjoying that chapter) but as far as I can tell that's mainly used to classify things (i.e. given a finite set of choices [x1...xn] which x is this given input) not really generate anything. I'm not even sure if this is possible or if it is what should I go about learning/figuring out. What algorithm is best suited for this? To those worried that I will use this as a bot to spam or provide bad answers to SO, I promise that I will not use this to provide (bad) advice or to spam for profit. I definitely will not post it's nonsensical thoughts on SO. I plan to use it for my own amusement. Thanks!

  • Load an html table from a mysql database when an onChange event is triggered from a select tag

    - by Crew Peace
    So, here's the deal. I have an html table that I want to populate. Specificaly the first row is the one that is filled with elements from a mysql database. To be exact, the table is a questionnaire about mobile phones. The first row is the header where the cellphone names are loaded from the database. There is also a select tag that has company names as options in it. I need to trigger an onChange event on the select tag to reload the page and refill the first row with the new names of mobiles from the company that is currently selected in the dropdown list. This is what my select almost looks like: <select name="select" class="companies" onChange="reloadPageWithNewElements()"> <?php $sql = "SELECT cname FROM companies;"; $rs = mysql_query($sql); while($row = mysql_fetch_array($rs)) { echo "<option value=\"".$row['cname']."\">".$row['cname']."</option>\n "; } ?> </select> So... is there a way to refresh this page with onChange and pass the selected value to the same page again and assign it in a new php variable so i can do the query i need to fill my table? <?php //$mobileCompanies = $_GET["selectedValue"]; $sql = "SELECT mname FROM ".$mobileCompanies.";"; $rs = mysql_query($sql); while ($row = mysql_fetch_array($rs)) { echo "<td><div class=\"q1\">".$row['mname']."</div></td>"; } ?> something like this. (The reloadPageWithNewElements() and selectedValue are just an idea for now)

  • Backdoor in OpenBSD how is it that no developer saw it ? And what about other Linux ? [closed]

    - by user310291
    It had been revealed that there have been backdoor implanted in OpenBSD http://www.infoworld.com/d/developer-world/software-security-honesty-the-best-policy-285 OpenBSD is opensource, how is it that nobody in the community developper could see it in the source code ? So how can one trust all the other "opensource" Linux Of course OpenBSD is only a case, the point is not about OpenBSD, it is about opensource in general. my question is not about Openbsd per se it's about source code os inspection especially c/c++ since most are written in these languages. Also once the source is compiled how one can be sure that it really reflects the source code ? If a law requires that a backdoor being implanted and obliges to deny that kind of action under the guise of security, how can you be sure that the system has not been corrupted by some tools ? As said there is there is a "nondisclosure agreement" My guess is that 99.99% of developpers in the world are just incapable of understanding os source code and won't even bother to look at it. And above all nobody wonders about why the gov wants such massive backdoor, and that of course they will pressure medias to deny.

  • What do you need to implement to provide a Content Set for an NSArrayController?

    - by whuuh
    Heys, I am writing something in Xcode. I use Core Data for persistency and link the view and the model together with Cocoa Bindings; pretty much your ordinary Core Data application. I have an array controller (NSArrayController) in my Xib. This has its managedObjectContext bound to the AppDelegate, as is convention, and tracks an entity. So far so good. Now, the "Content Set" biding of this NSArrayController limits its content set (as you'd expect), by a keyPath from the selection in another NSArrayController (otherAc.selection.detailsOfMaster). This is the usual way to implement a Master-Detail relationship. I want to variably change the key path at runtime, using other controls. This way, I sould return a content set that includes several other content sets, which is all advanced and beyond Interface Builder. To achieve this, I think I should bind the Content Set to my AppDelegate instead. I have tried to do this, but don't know what methods to implement. If I just create the KVC methods (objectSet, setObjectSet), then I can provide a Content Set for the Array Controller in the contentSet method. However, I don't think I'm binding this properly, because it doesn't "refresh". I'm new to binding; what do I need to implement to properly update the Content Set when other things, like the selection in the master NSArrayController, changes?

  • How to properly log out of facebook

    - by Gublooo
    This is a repeated question and I have followed both the suggestions provided in these StackOverflow links: How to log-out users using FaceBook connect in php and zend Trouble logging out of a FaceBook connect site and destroying sessions The issue is - the code works 90% of the time. Thats the weird part. Out of the 100 times I've logged in and out - I've experienced this problem 5-6 times and 2 of my beta test users have reported the same issue. So when it works- if u click the logout link - u get the facebook popup saying - you being logged out - when it does'nt work - absolutely nothing happens - the page does not refresh - it just sits on that page doing nothing. This is the javascript code that gets called on clicking logout function logout() { FB.Connect.get_status().waitUntilReady(function(status) { switch(status) { case FB.ConnectState.connected: FB.Connect.logoutAndRedirect("http://www.example.com/login/logout"); break; case FB.ConnectState.userNotLoggedIn: window.location = "http://www.example.com/login/logout"; break; } }); return false; } This is the php code: $this-_auth-clearIdentity(); $face = Zend_Registry::get('facebook'); $fb = new Facebook($face['appapikey'], $face['appsecret']); //$fb-clear_cookie_state(); $fb-expire_session(); Anyone experienced such sporadic issues. Thanks
