• Autoplay an Audio File on Mobile Safari

  - by phantomdata

  Hey guys, I've got a little system dashboard web app that I've written, replete with alarm notifications. I've had it working for quite some time on mobile safari, but recently wanted to add audio to the alarm notifications to allow me to easily know when there are alarms and I'm not looking directly at the display. The alarm notifications are populated through a (relatively) constantly polling ajax request that pulls in and displays an alarm banner if alarms are present. I wanted to add an auto-playing 'alarm' sound as well, but no dice for Safari Mobile. I've tried using HTML5 and embedded objects with no avail. The Apple documentation does state that you can't auto-play an audio file and it must be activated through user action to conserve bandwidth. Has anyone found a way around this in a WLAN setting?

• iPhone TabBar selection cancelling

  - by Chris Schnyder

  I am developing an iPhone app that displays several views, all acessed via Tab Bar items. However I need to add an additional item to the Tab Bar that simply launches a URL in Safari. I've accomplished this by adding an empty placeholder view to the TabBar and returning FALSE from shouldSelectViewController when the this view's tabBarItem is clicked on, and launching Safari at the same time. That code is: - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController { if([[viewController tabBarItem] title] == "Website"){ //... launch Safari return FALSE; } else { return TRUE; } } PROBLEM: If the TabBar has too many items, and this "Safari Launch" tab is pushed off to the "More" navigation controller, I lose the capability to intercept the event and prevent the view from loading when clicked. Any suggested tips?

• How to handle multiple delegates

  - by mac_55

  I've got a view in my app that does pretty much everything, and I like it that way. The problem however is that it's implementing 5 or 6 different delegates, which seems a little bit messy. My question is, does the view controller have to implement all of the delegates? or is there some way I can separate the code out into different files (without having to do a major restructure or rewrite)? Here's all the delegates I'm implementing: @interface MyView : UIViewController <UIScrollViewDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIActionSheetDelegate, MFMailComposeViewControllerDelegate>

• How can I transform this haml into a table?

  - by mmr

  I have the following haml code: - @theLinks.each_index do |x| %br %form{:action=>'/Download', :method=>"post",:enctype=>"multipart/form-data"} %input{:type=>"submit", :name=>"#{@theLinks[x].url}", :value=>"Name: #{@theLinks[x].Name} Study Time: #{@theLinks[x].studyTime} Comments: #{@theLinks[x].comments}"} Basically, for each person, list the time they participated in a study and the comments on the study. Right now, this renders as a set of buttons. I'd like to render it as a table, with each row clickable in the same way (ie, using the 'post' method, so that only the haml file has to be edited without touching the rest of the files). Ideally, I'd also like to be able to sort the table by name, time, or comments, but that might be getting ahead of myself. So how can I change this list of buttons into a table with clickable rows?

  Hello everybody, When i update the existing subscription info using update_recurring method of autorize.net gateway then payment details(means 'credit card number', 'CVV number' and 'expiry date' ) are not being updated. My code snippet is as follows:- def create_card_subscription credit_card = ActiveMerchant::Billing::CreditCard.new( :first_name = params[:payment_details][:name], :last_name = params[:payment_details][:last_name], :number = params[:payment_details][:credit_card_number], :month = params[:expiry_date_month], :year = params[:expiry_date_year], :verification_value = params[:payment_details][:cvv_code] ) if credit_card.valid? gateway = ActiveMerchant::Billing::AuthorizeNetGateway.new(:login = '***', :password = '******') response = gateway.update_recurring( { "subscription.payment.credit_card.card_number" = "4111111111111111", :duration ={:start_date='2010-04-21', :occurrences=1}, :billing_address={:first_name='xyz', :last_name='xyz'}, :subscription_id="**" } ) if response.success? puts response.params.inspect puts "Successfully charged $#{sprintf("%.2f", amount / 100)} to the credit card #{credit_card.display_number}.

• How do I return JSON data from a partial view FormMethod.Get?

  - by MrM

  I have the following code that posts to my Search Json. The problem is the url redirects to the json search and displays the raw json data. I would like to return to a table in my partialView instead. Any thoughts on how I can achieve this? <div> @using (Html.BeginForm("Search", "Home", Formmethod.Get, new {id="search-form"})){ ... <button id="search-btn">Search</button> } </div> <div> <table id="search-results">...</table> </div> My home controller works fine but to make sure the picture is clear... public JsonResult Search(/*variables*/) { ... return Json(response, JsonRequestBehavior.AllowGet); } And I get redirected to "Search/(all my variables)

• Render view as string then redirect.

  - by JohnRudolfLewis

  In my ASP.NET MVC application, I would like my controller action to render a view to a string, send an email using that string as the body, then do a redirect. I've found several articles here on SO and elsewhere on how to render the view to a string. That part was easy. But when I attempt to perform the redirect, I get an HttpException: Cannot redirect after HTTP headers have been sent. I've tried setting Response.Buffer and Response.BufferOutput to true, I've tried Response.Clear, nothing seems to work. Is it possible to render a view to a string, then do a redirect?

• Needing to copy properties before validation

  - by Mikael

  I have a farily complex model needing to be validated, the problem is that this model is used on two different places, one where you register your customer and one where you simply add addresses. Some fields on the address are simply not visible on the register customer form. So when i check if ModelState.IsValid i get false of course since eg. the name is not entered on the billing address, but it is on the customer. That is why i want to before validation occurs, copy a couple of fields to the model, and then validate. I am somewhat lost though and i need help. My action looks something like this: public ActionResult Register(WebCustomer customer) { customer.CopyProperties(); if(TryUpdateModel(customer)) { ... } ... But it always returns false, and ModelState.IsValid continues to be false.

• Sharing view logic in Django

  - by Jeremy B.

  I've begun diving into Django again and I'm having trouble finding the parallel to some common concepts from my life in C#. While using .NET MVC I very often find myself creating a base controller which will provide a base action implementation to take care of the type of stuff I want to do on every request, like retrieving user information, getting localization values. Where I'm finding myself confused is how to do this in Django. I am getting more familiar with the MVT concept but I can't seem to find how to solve this scenario. I've looked at class based views and the generic views yet they didn't seem to work how I expected. What am I missing? How can i create default logic that each view will be instructed to run but not have to write it in each view method?

• Generating Component SEF URLs in Joomla

  - by Jarrod

  I have a custom Joomla component and a router for building my SEF URL's for use within the site, and everything is usually shiny - internally, all of my links look and act fantastic. I recently route a controller action that sends a list of links through email, and I've noticed that my URLs are coming out.... funky - hopefully someone can tell me why. Usually, my router generates an internal link that looks like this: http://localhost/Registry/calendar/265889635/Some-Long-Boring-Event However, when I send an email and preparing the same URL through the same router I get: http://localhost/Registry/Registry/component/calendar/569555803/Some-Long-Boring-Event Has anybody run into this issue before?

• jqueryForm and empty uploads

  - by Aiden Bell

  Hi All, Been scratching my head for too long on this: Using jquery.form, (http://malsup.com/jquery/form) with PHP ... my $_FILES['someimage'] gets set but the error number is always UPLOAD_ERR_NO_FILE, size is also 0. The JavaScript: $('form input[type=file]').change(function(){ $(this).clone().appendTo('#imgform'); $('#imgform').ajaxForm(); $('#imgform').ajaxSubmit( { type:'POST' } ); }); Which appends to: <form id="imgform" method="POST" action="/api/images.php" enctype="multipart/form-data"></form> From another form which has bog-standard file inputs. PHP logs are clean, but var_dumping $_FILES always shows that the index is set to the name of the form element ... but no data. Thanks guys! (Sorry, I know jQuery-like questions are too frequent round these parts).

• Lazy Tables app from iphone

  - by Warrior

  I am new to iphone development. I have parsed a youtube file and displaying its contents with the image in the table view. But the scrolling has become slower because of displaying image.So i want to display the image as the lazy tables program from apple docs.Since they have used navigation based application , their rootviewcontroller loads first and then the delegate class call the parsing ,and when they reload the table view, the contents are displayed. The data array count shows 25. I am using a view controller to display the tables on the present modal view, more over when i run my application, first delegate methods call the parsing. So when i click the youtube icon in my landing page it navigates to table view. So by this time data array count shows 0. I have created table view in interface builder and set the outlets to the file owner properly. Please help me out. I want to increasing the scrolling performance. Thanks.

• How to get Jquery form plugin and Jquery validation to work together.

  - by Matthew

  Hello guys, I was hoping someone can shed some light on what might be occurring on my page. Okay what I currently have on my page is a simple form that collects first name, last name, city, state and email. Once submitted it will hit a PHP page that updates our DB and echo's back to the designted div with a class of .response. I am using jquery.validation and placing that dynamic function within the submitHandler like so: submitHandler: function(form) { $(form).ajaxSubmit({ target: '.response', // target element(s) to be updated with server response resetForm: true, success: function() { $('#commentform').hide(); $('.response').show(); } }); So what I am getting is a div that is not being populated with the echo from my php file in FF and in IE I am getting the message of thank you but the page is taking me to the update.php script in which I have the form action pointing to. I am not sure what I am missing... Thanks, Matt

• Zend Regex Route > Track the api version

  - by dskanth

  Hi, i am building a web service with zend and i am using modules to separate my api versions. Ex: "applications/modules/v1/controllers", "applications/modules/v2/controllers" have different set of actions and functionality. I have made "v1" as the default module in "application.ini" file: resources.modules = "" resources.frontController.defaultModule = "v1" resources.frontController.moduleDirectory = APPLICATION_PATH "/modules" resources.frontController.moduleControllerDirectoryName = "controllers" I have written the following in my bootstrap file: $router = $front->getRouter(); $r1 = new Zend_Controller_Router_Route_Regex('api/v1/tags.xml', array('module' => 'v1', 'controller' => 'tags', 'action' => 'index')); $router->addRoute('route1', $r1); Suppose, if this is my url: http://localhost/api/v1/tags.xml then it belongs to version 1 (v1). But i dont want to write many routes like this one, so i want to know how can i track the version from the regex url and dynamically determine the api version to be used (1 or 2).

• How can I replace jQuery Tools Scrollable bullets with numbers?

  - by Steven

  I'm using jQuery Tools for creating an article carousel. You can see in action with images here: http://flowplayer.org/tools/demos/scrollable/plugins/index.html The navigation code looks like this: <!-- wrapper for navigator elements --> <div class="navi"></div> And the plugin ads links like so: <!-- wrapper --> <div class="navi"> <a href="0" class="active"/> <a href="1" class=""/> <a href="2" class=""/> </div> The code to get it all started goes like this: $(".scrollable").scrollable({ circular: true, size: 1}).navigator(); My question is: How can I replace <a href="1" class=""/> with <a href="1" class=""> [1] </a> ?

• If Possible, How Can One Set Either a Background Color on Cells within a Sizer or Gridlines for the

  - by MetaHyperBolic

  I am flailing about with wxWidgets, in particular, the wx.Sizer in wxPython. I have read the documents, I have a copy of wXPython in Action before me, and have set aside the problem to work on other things a better mental model of sizers hopefully gestated within my skull. None of this has worked. I am not grokking, or even getting to the point where I can bang about usefully, how sizers work. In HTML, I could at least set a background color on some div or td, or call forth borders so I could see how things are laid out. Here, I have a grey expanse and no idea which of the nested static box sizers from which it originates. I am giving static box sizers after making a mess out of the grid bag sizers. Either alternative would let me at least get a handle on how these work.

• Approaches to wrapping access to functionality in .NET MVC?

  - by Kevin

  What are some different solutions to wrapping access to functionality within a .NET MVC application? For example, I have six tabs that represent different areas of the application and within area 1, there is the ability to add, edit, upload, whatever. I need a central way to say: Build some dictionary of what the user can do Wrap tabs, buttons, links, etc, validate the user can access this piece of functionality and show/hide appropriately. I know I can restrict access to actions via action filters and roles, but what about from the UI? Any help would be appreciated. I am sure I am not the only one who has needed to do this, thanks!

• How to programatically record the start and end of an MVC FileResult for logging of incomplete downl

  - by Richard

  Hi, I have been investigating how My ASP.NET MVC application can log unsuccessful / incomplete downloads. I have a controller handling the file requests which currently returns a FileResult. What I need to record is the IPAddress, filename and when the download started, then the same data and when it completed. I have looked at intercepting the request start and end with an HttpModule and also IIS7 failed request tracing but am not sure which route would be best and have this feeling that maybe I am missing an obvious answer to the problem. Does anyone have any suggestions or know of any alternatives as this seems like something many people would want to know from their web server? Thanks for your help

• Handling dynamic data from javascript or rails

  - by 99miles

  I have page consisting of a calendar view ( http://code.google.com/p/calendardateselect/ ) as well as divs, each of which contain information about a person. In each div I want to have a link to a new controller and action, and pass the id for the person and the date selected in the calendar. I can think of a one way, but I'm thinking there's likely a better solution: 1) Do something like: =link_to_function "Week", "weekClicked(#{person.id})" Then in the weekClicked() javascript method I get the selected date from the calendar, such as: $('e_date').selected_date; then with javascript I could make a post request as mentioned here: http://stackoverflow.com/questions/133925/javascript-post-request-like-a-form-submit 2) Or, is there a way that I could make each link a button in it's own form and maybe have a hidden field that gets the selected date from the calendar as or before the form is submitted? I tried this too, but couldn't figure it out. This definitely seems like it's more on the right track than #1. Thanks.
