  • Detecting taps on a UIWebView

    - by dubbeat
    Hi, I'm trying to find a way to detect a double tap on a UIWebview. I want to use this action to close it. I however can't find and methods in the documentation for UIWebview taps. Whats the best to add taps to a uiwebview? I tried a tutorial here http://mithin.in/2009/08/26/detecting-taps-and-events-on-uiwebview-the-right-way/ But I don't know how to change my UIWindow to a tap detecting window. Does the above link seem like the best approach or could you suggest another way to remove my WebView?

  • Zend Framework: Flash Messenger, add a message from the model

    - by Dan
    Any idea on how best to add a message to flash messenger from the model? As FlashMessenger is an action helper, this seems not to be possible, so the obvious solution is to create an internal message object in the model, and return that to the controller from where you can use addMessage(). But if you want to return something else as well, this falls down. Another idea is an additional session namespace for these internal messages, which is then merged in with the Flash Messenger namespace messages at output time? Anyone have any thoughts or experience on this? Cheers.

  • SQL Server Process Queue Race Condition

    - by William Edmondson
    I have an order queue that is accessed by multiple order processors through a stored procedure. Each processor passes in a unique ID which is used to lock the next 20 orders for its own use. The stored procedure then returns these records to the order processor to be acted upon. There are cases where multiple processors are able to retrieve the same 'OrderTable' record at which point they try to simultaneously operate on it. This ultimately results in errors being thrown later in the process. My next course of action is to allow each processor grab all available orders and just round robin the processors but I was hoping to simply make this section of code thread safe and allow the processors to grab records whenever they like. So Explicitly - Any idea why I am experiencing this race condition and how I can solve the problem. BEGIN TRAN UPDATE OrderTable WITH ( ROWLOCK ) SET ProcessorID = @PROCID WHERE OrderID IN ( SELECT TOP ( 20 ) OrderID FROM OrderTable WITH ( ROWLOCK ) WHERE ProcessorID = 0) COMMIT TRAN SELECT OrderID, ProcessorID, etc... FROM OrderTable WHERE ProcessorID = @PROCID

  • How to pass get-parameter to backing bean in jsf?

    - by Roman
    I have get parameter with name controller. When I try to pass it (with propertyChangeListener) to my backing bean I get null instead of the real value of the parameter: <h:commandButton value="#{msg['mail.send']}" styleClass="mailbutton" action="#{mailSender.sendMail}"> <f:setPropertyActionListener target="#{mailSender.controllerName}" value="{#param.controller}"/> </h:commandButton> So, I have two questions: What is the proper way to set bean property with a get-parameter value? Actually, I've already get the value from ExternalContext#getRequestParam but maybe there are some other solutions. More interesting question: why propertyActionListener didn't work here? What does it do actually? (again I have some thoughts about it but it would be nice to read more comprehensive explanations).

  • Is it normal that conversationId keeps increasing after each page request?

    - by Casper
    Hi I'm building a Seam application and have a question: I got a stateless session bean (default seam scope) with a delete and a select method. A page which contains a datamodel loads and got links to select and delete each row (both links refer to the actionmethods in the bean). The delete method deletes the selected row from the list and returns null (reloads page). The select method loads a new page where the selected row can be edited. Each time a link in the datamodel is clicked and an action gets fired, the conversationId gets increased. Is this normal behaviour since im not even in a conversation? If it ain't normal behaviour, what's best practice to prevent this from happening?

  • Boiler plate code replacement - is there anything bad about this code?

    - by Benjol
    I've recently created these two (unrelated) methods to replace lots of boiler-plate code in my winforms application. As far as I can tell, they work ok, but I need some reassurance/advice on whether there are some problems I might be missing. (from memory) static class SafeInvoker { //Utility to avoid boiler-plate InvokeRequired code //Usage: SafeInvoker.Invoke(myCtrl, () => myCtrl.Enabled = false); public static void Invoke(Control ctrl, Action cmd) { if (ctrl.InvokeRequired) ctrl.BeginInvoke(new MethodInvoker(cmd)); else cmd(); } //Replaces OnMyEventRaised boiler-plate code //Usage: SafeInvoker.RaiseEvent(this, MyEventRaised) public static void RaiseEvent(object sender, EventHandler evnt) { var handler = evnt; if (handler != null) handler(sender, EventArgs.Empty); } } EDIT: See related question here UPDATE Following on from deadlock problems (related in this question), I have switched from Invoke to BeginInvoke (see an explanation here). Another Update Regarding the second snippet, I am increasingly inclined to use the 'empty delegate' pattern, which fixes this problem 'at source' by declaring the event directly with an empty handler, like so: event EventHandler MyEventRaised = delegate {};

  • Easier way to generate paths

    - by Horace Loeb
    Songs on Rap Genius have paths like /lyrics/The-notorious-b-i-g-ft-mase-and-puff-daddy/Mo-money-mo-problems which are defined in routes.rb as: map.song '/lyrics/:artist_slug/:title_slug', :controller => 'songs', :action => 'show' When I want to generate such a path, I use song_url(:title_slug => song.title_slug, :artist_slug => song.artist_slug). However, I'd much prefer to be able to type song_url(some_song). Is there a way I can make this happen besides defining a helper like: def x_song_path(song) song_path(:title_slug => song.title_slug, :artist_slug => song.artist_slug) end

  • How to "kill" background worker completely?

    - by Ken Hung
    Hi All, I am writing a windows application that runs a sequence of digital IO actions repeatedly. This sequence of actions starts when the user click a "START" button, and it is done by a background worker in backgroundWorker1_DoWork(). However, there are occasions when I get the "This backgroundworker is currently busy......." error message. I am thinking of implementing the following in the code, by using a while loop to "kill" the background worker before starting another sequence of action: if (backgroundWorker1.IsBusy == true) { backgroundWorker1.CancelAsync(); while (backgroundWorker1.IsBusy == true) { backgroundWorker1.CancelAsync(); } backgroundWorker1.Dispose(); } backgroundWorker1.RunWorkerAsync(); I think my main concern is, will the backgroundWorker1 be "killed" eventually? If it will, will it take a long time to complete it? Will this coding get me into an infinite loop?

  • How to cache queries in Rails across multiple requests

    - by m.u.sheikh
    I want to cache query results so that the same results are fetched "for more than one request" till i invalidate the cache. For instance, I want to render a sidebar which has all the pages of a book, much like the index of a book. As i want to show it on every page of the book, I have to load it on every request. I can cache the rendered sidebar index using action caching, but i also want to actually cache the the query results which are used to generate the html for the sidebar. Does Rails provide a way to do it? How can i do it?

  • JQuery text display problem?

    - by SLAPme
    Kind of new to JQuery and I was wondering how can I state that the users submitted info was saved when they click the submit button by displaying the message Changes saved at the top of the form and then have it disappear when the user leaves the web page and return back to it? Right now my code only displays that changes were saved at the bottom of the form outside of the lists and will not disappear when the users leave the web page and return back to it. Here is the JQuery code. $(function() { $(".save-button").click(function() { $.post($("#contact-form").attr("action"), $("#contact-form").serialize(), function(html) { $("div.contact-info-form").html(html); $('#contact-form').append('<li>Changes saved!</li>'); }); return false; // prevent normal submit }); }); Here is the html code. <div id="contact-info-form" class="form-content"> <h2>Contact Information</h2> <form method="post" action="index.php" id="contact-form"> <fieldset> <ul> <li><label for="address">Address 1: </label><input type="text" name="address" id="address" size="25" class="input-size" value="<?php if (isset($_POST['address'])) { echo $_POST['address']; } else if(!empty($address)) { echo $address; } ?>" /></li> <li><label for="address_two">Address 2: </label><input type="text" name="address_two" id="address_two" size="25" class="input-size" value="<?php if (isset($_POST['address_two'])) { echo $_POST['address_two']; } else if(!empty($address_two)) { echo $address_two; } ?>" /></li> <li><label for="city_town">City/Town: </label><input type="text" name="city_town" id="city_town" size="25" class="input-size" value="<?php if (isset($_POST['city_town'])) { echo $_POST['city_town']; } else if(!empty($city_town)) { echo $city_town; } ?>" /></li> <li><label for="state_province">State/Province: </label> <?php echo '<select name="state_province" id="state_province">' .

  • Strange problem with SEAM stateful session bean

    - by John
    Hi, I've got a staeful session bean. @Scope(ScopeType.SESSION) @Name("chuckNorrisBean") public class ChuckNorrisBean implements Serializable, ChuckNorris with some function public void roundHouseKick() { ... } interface @Local public interface ChuckNorris { public void roundHouseKick() { ... } } and calling them on a jsf .xhtml page using #{chuckNorrisBean.roundHouseKick} which works perfectly fine. However if I add the @Stateful annotation to the bean so it becomes @Stateful @Scope(ScopeType.SESSION) @Name("chuckNorrisBean") public class ChuckNorrisBean implements Serializable, ChuckNorris and the page will load with exceptions complainig about Exception during request processing:Caused by javax.servlet.ServletException with message: "#{chuckNorrisBean.roundHouseKick}: javax.el.MethodNotFoundException: //localhost/universe/earth.xhtml @41,65 action= "#{chuckNorrisBean.roundHouseKick}": Method not found: ChuckNorrisBean:a6gkg-w6das4-g8wmgh0y-1-g8woy0wo-4b.roundHouseKick()" Any advice on what might've went wrong with my chuckNorrisBean?

  • Zend remove anchor text in url redirect

    - by user351785
    I have a form that is using an anchor name as it's action so that when the form is submitted it is it goes straight back to the form (for example 'www.domain.com/page#contact-form). The idea is if there are any errors then it'll go straight to the form (that's near the bottom of the page) so you can see the errors and continue filling in the form. If the form is valid, I want it to redirect to another page (for example www.domain.com/another-page). The problem is that the redirect url still has the anchor text in the url (in the above example it is www.domain.com/another-page#contact-form). I am using $this->_helper->redirector->goToRouteAndExit(array(), 'another-page', true); to goto the another-page route. I have tried setting the url specifically but that doesn't fix it either. How do I redirect to another page and remove that anchor text from the url?

  • Route all requests through PageController except existing controllers (Zend Framework)

    - by ChrisRamakers
    For a new CMS i've developed a Pages module that allows me to manage the site's tree structure. Each page is reachable from the url http://www.example.com/pageslug/ where pageslug identifies the page being called. What I want to achieve now is a route that allows me to route all incoming requests to a single PagesController unless it's a request to an existing controller (like images for example). It's easy enough to catch all requests to the Pages Controller but how to exclude existing controllers? This is my module bootstrap. How can i achieve this in the most preferrable way <?php class Default_Bootstrap extends Zend_Application_Module_Bootstrap { protected function _initRoute() { $this->bootstrap('frontController'); /* @var $frontcontroller Zend_Controller_Front */ $frontcontroller = $this->getResource('frontController'); $router = $frontcontroller->getRouter(); $router->addRoute( 'all', new Zend_Controller_Router_Route('*', array('controller' => 'pages', 'action' => 'view') ) ); } }

  • Calling function from popover.

    - by user288225
    Alright, so I made a popover from my main view and all that good stuff. But I want to have my popover call an action in my main view when a button within the popover is pressed. MainView *mainView = [[MainView alloc] initWithNibName:@"MainView" bundle:nil]; [mainView doStuff]; The "dostuff" function changes some elements within the view. For example, the color of the toolbar is supposed to be changed. I've put a print command and the print command executes. But for some reason, the toolbar won't change color. I've imported the header of MainView into the popover. I did an @class thingy for MainView in my popover. doStuff is declared in MainView's header. The IBOutlets are declared too, and connected. Any ideas?

  • ASP.NET MVC Authentication Cookie Not Being Retrieved

    - by Jamie Wright
    I am having a hard time implementing "Remember Me" functionality in an MVC application with a custom principal. I have boiled it down to ASP.NET not retrieving the authentication cookie for me. I have included a snaphot below from Google Chrome. Shows the results of Request.Cookies that is set within the controller action and placed in ViewData for the view to read. Notice that it is missing the .ASPXAUTH cookie Shows the results from the Chrome developer tools. You can see that .ASPXAUTH is included here. Does anyone know what the issue may be here? Why does ASP.NET not read this value from the cookie collection?

  • ASP.NET MVC as a service host for SOA like architecture

    - by Delucia
    I'm creating a distributed application that includes a lot of services and I'm looking for the technology that allows me to create and manage a lot of services easily. I know managing and deploying windows services is not fun. I'm thinking of using ASP.NET MVC as service host of my services where each controller action becomes essentially a service and I can communicate with a service via simple HTTP request and responses and not have to deal with complexity if i use something like WCF. Services need to be isolated and asp.net requests are isolated as far as i know, i.e. if a request throws an exception it will not effect other running requests. But I still have questions about the management of the services. How will it be possible to see which services are running, stopping and resuming services. Also ASP.NET MVC are passive, i.e. they only do something upon a request but what if i want to service that initiates work by itself?

  • OpenID register on login (authlogic_openid)

    What is the proper way to register users automatically when they log in with openid? I am using authlogic with an authlogic-oid gem (and an older version of openid_authentication). The stuff I read online so far seems to be obsolete. Does anyone know the proper way to do it with the new gem? What I do now is: options = params[:user_session] || {} [:openid_identifier].each { |k| options[k] = params[k] if params[k] } @user_session = UserSession.new(options) @user_session.save do |result| if result flash[:notice] = "Login successful! (#{result.inspect})" redirect_back_or_default account_url else render :action => :new end end By the way, I don't see the Login Successful flash (but that is not that big of a deal).

  • Learning OOP Design

    - by waiwai933
    I've read Head First Java, and I understand how OOP works. Here's my problem: I'm a PHP programmer, and while I've used OOP in PHP, I'm having trouble figuring out what should be an object and what methods to give it. For example, let's say I have a app that allows people to log in and edit a document. Why should the document be an object if there will ever only be one instance? Should I give the deleteDocument() method to the document object or the admin object? The document is the one being deleted, but the admin is the one performing the action. So my real question is, coming from a procedural background, how do I figure out what should be objects and what should have what methods?

  • ActionScript 3 class over several files - how?

    - by Poni
    So, how do we write a class over several files in action script 3? In C# there's the "partial" keyword. In C++ it's natural (you just "#include ..." all files). In Flex 3, in a component, you add this tag: <mx:Script source="myfile.as"/>. How do I split the following class into several files; package package_path { public class cSplitMeClass { public function cSplitMeClass() { } public function doX():void { // .... } public function doY():void { // .... } } } For example I want to have the doX() and doY() functions implemented in another ".as" file. Can I do this? And please, don't tell me something like "a good practice is to have them in one file" :)
