• iOS - Losing in-app subscription?

  - by user3280451

  I've just built an iOS app that uses a non-reoccuring subscription model. You hit "buy" and then when the client device receives the receipt from the Apple server it whizzes it off to my server to validate it and add the subscription to my user database. If the connection fails before my server has responded then the request is cached, ready to be resent the next time the client comes online. My problem is, what happens if the connection fails between when the user hits the buy button and the receipt is received by the client from Apple? Theres no way for it to know that the purchase has been made? Presumably I should add a "restore purchases" button that sends all of the users receipts to my server which checks if they've already been validated and their respective subscriptions added to the database? Is there a less intrusive way of doing this?

• Is there any real advantage to use zend ce server over just referencing (include) the zend framework library?

  - by Marcos Roriz

  Hi, I'm new to PHP frameworks, and currently I'm trying Zend Framework (ZF). I'm old fashioned when it comes to installing software, I like to install apache/mysql/php all separetely since I find easier and it gives me more control of it. It seems that the "encouraged" way to develop with Zend Framework is using the Zend (CE) Server. I personally don't like this idea of a app install everything else (PHP/Apache and so on). From what I've seen if I include Zend Framework Library in php.ini path I'm ready to go. So is there any real advantage to use the Full Zend (CE) Server??

• jQuery Toggle Help

  - by Cameron

  I have the following code: $(document).ready(function() { // Manage sidebar category display jQuery("#categories > ul > li.cat-item").each(function(){ var item; if ( jQuery(this).has("ul").length ) { item = jQuery("<span class='plus'>+</span>").click(function(e){ jQuery(this) .text( jQuery(this).text() === "+" ? "-" : "+" ) .parent().next().toggle(); return false; }); jQuery(this).find(".children").hide(); } else { item = jQuery("<span class='plus'>&nbsp;</span>"); } jQuery(this).children("a").prepend( item ); }); }); This creates a sort of toggle system for my categories. But it will only work with 2 levels deep, what I need it to do is work with unlimited levels.

• Is there away to load a page only once with AJAX?

  - by digitup

  I have an AJAX call to load a function once the page is loaded, the function opens a lightbox a like frame with some data. The issue is that if I click on close (lightbox frame), the page loads again and again loading the frame so the use never reaches the page under the layer of frame since the frame load on infinite loop. The Ajax is repeating calling the function I guess but I would like to load the frame once and when the user clicks X (close) he may return to the original page. $(document).ready(function(){ var city = $('#citycode').html(); $.ajax({ //when page is loaded, fire the following function success: function(){ //the function to be fired located in the page in seperate file openX(city + //some other parameters); }}); }); Any tips?

• Allow users to enter a variable length list of items in asp.net form

  - by EJB

  I need to let my users enter a variable length list of items into something that looks like a grid view (or a series of standard text boxes stacked vertically). Each item could be a few characters or a few hundred characters long, and I just want them to enter a "sentence", and then tab to the next row, and always having another blank one ready to go at the bottom of the list. I don't want to save any data to my SQL Server DB until they enter the entire list and then click on a "save all" button. When they hit the "save all" button they will be given a preview screen where the data will be presented as standard HTML ordered list. If they confirm/save, then each row of the grid will then be saved as a separate row into my SQL Server database (with an index to remember the order). What ASP.Net (or Jquery/javascript) UI control would be the best to use in this situation?

• C# Multi threading- Move objects between threads

  - by Grant

  Hi, i am working with a winforms control that is both a GUI element and also does some internal processing that has not been exposed to the developer. When this component is instantiated it may take between 5 and 15 seconds to become ready so what i want to do is put it on another thread and when its done bring it back to the gui thread and place it on my form. The problem is that this will (and has) cause a cross thread exception. Normally when i work with worker threads its just with simple data objects i can push back when processing is complete and then use with controls already on the main thread but ive never needed to move an entire control in this fashion. Does anyone know if this is possible and if so how? If not how does one deal with a problem like this where there is the potential to lock the main gui?

• How to hide/show div using jQuery without altering dimensions?

  - by Byron S

  I have a div that is holding a google chart: <div id="chart_div" style="width: 600px; height: 300px;"></div> It has one CSS property: display: none. On the click of a button, I would like to have the chart be displayed using jQuery hide() and show(). It's working, however, the chart's dimensions are set to something different than I have specified and refuse to change to what I have specified. Here is my jquery code: $(document).ready(function(){ var chart = $('#chart_div'); $('#submit').click(function(){ chart.show('slow'); }); }); Let me know if theres any more code you would like to see. By the way, the chart div is not being contained in anything else so that isn't the problem.

• A non-blocking server with java.io

  - by Jon

  Everybody knows that java IO is blocking, and java NIO is non-blocking. In IO you will have to use the thread per client pattern, in NIO you can use one thread for all clients. Now my question follows: is it possible to make a non-blocking design using only the Java IO api. (not NIO) I was thinking about a pattern like this (obviously very simplified); List<Socket> li; for (Socket s : li) { InputStream in = s.getInputStream(); byte[] data = in.available(); in.read(data); // processData(data); (decoding packets, encoding outgoing packets } Also note that the client will always be ready for reading data. What are your opinions on this? Will this be suitable for a server that should at least hold a few hundred of clients without major performance issues?

• svn update overwrite local copy - can I retrieve local copy?

  - by Myx

  Hi: So I was editing a file on my local machine and I was ready to commit to the repository except that instead of running the svn commit, I ran svn update. Is there any way I can retrieve the changes that I had? I was working on a tex file in vim and I had closed the file before running svn update. Thanks. EDIT: I'm sorry - I completely was worried for nothing (project deadline in 30 mins and I thought I deleted all my changes). I realize that when I run svn update, it doesn't rewrite the local changes but tries to merge the files if there are no conflicts. Can someone tell me how to close or remove this post? Thanks.

• jQuery/Javascript problem with IE

  - by Shadyn

  I have two radio buttons each with a unique ID. When one is clicked, I would like to add $10 to a total. When the other is clicked, we go back to the original total price. My jquery looks like this: function check_ceu() { var price = <%= conference_price %>; if($('#ceu_yes').is(':checked')){ $('#total').val(parseFloat(price) + 10) } else{ $('#total').val(price) } } I have this function bound to document.ready (for page refreshes) and also the onchange handler of the radio buttons. In FF and Chrome this works fine. In IE, when the radio button with ID of "ceu_yes" is checked nothing happens, then when clicking back to the other radio button, 10 is added. So in essence, IE has the checkbox functionality reversed. Below is my code for the buttons: <input type="radio" name="ceu" id="ceu_yes" value="1" onchange="check_ceu()" /> $10 <input type="radio" name="ceu" id="ceu_no" value="0" checked="checked" onchange="check_ceu()" /> No, thank you Any ideas on this?
