• Rotation of ViewController in TabbarController

  - by hanno

  I have a custom UIViewController in a UITabbarController and want to respond to rotation events. When a rotation occurs, the tabbarcontroller and the viewcontroller get rotated. However, the view in the viewcontroller doesn't get redrawn properly: the layout doesn't autoresize and it is black on parts of the screen. The strange thing is that it works when I go to another tab and the back again to my original viewcontroller. What could possibly be wrong? I checked that didRotateFromInterfaceOrientation:fromInterfaceOrientation is being called. However, the view.frame.size values are still the old ones from before the rotation. That's probably not correct.

• Is there a Cart/Catalog app out there that isnt a full site?

  - by prodigitalson

  Every solution i come across seems to be a complete store with far too many options and too much functionality. I can write my own cart to get the minimal functionality i need out of the frontend, im just trying to cut out the time writing a complex backend. What im really looking for is something that offers the backend functionality for a product catalog, order management, etc. while providing a smooth and consistent API to access the data for my completely custom frontend application. The frontend will be in PHP so the API would have to be native PHP or some kind of web service interface i can create my own php models around. It would need to run on a LAMP stack and would preferably be written in PHP, Python, or Ruby just in case i need to customize the backend (she curently has ZenCart and hates it - says its far too complicated and sophisticated for her needs). Does such a thing exist? Or what would be the next best thing?

• jQuery to target CSS a:hover class

  - by songdogtech

  Confused here. What's the best way to change the hover CSS of the link below, and how? toggle.Class? add.Class? I want to show an image on hover. I have been able to change the color of the text with $("#menu-item-1099 a:contains('rss')").css("color", "#5d5d5d"); but can't seem to target the hover class. <div id="access"> <div class="menu-header"> <ul id="menu-main-menu" class="menu"> <li id="menu-item-1099" class="menu-item menu-item-type-custom menu-item-1099"> <a href="http://mydomain.com/feed/">rss</a></li>

• Working with the Grails g:timeZoneSelect tag?

  - by tinny

  I am wanting to use the g:timeZoneSelect tag within my application, problem is im finding the resulting html select to be quite overwhelming. Over 600 options are being displayed, IMHO this is to much to display to the user. Maybe someone could point me to an example of a much more manageable list of timezones? Maybe you have seen a site that does timezone selection well? Im sure over 600 option is "technically" correct, but this will just look like noise to the user. The display value of the timezone is to long. E.g. "CST, Central Standard Time (South Australia/New South Wales) 9.5:30.0" Just "CST, Central Standard Time" or "Australia/Broken_Hill" would be better Is there a way to address these issues via tag attributes of some sort (cant find any in the docs) or config that I am unaware of? Or, is my best bet to wrap an html select within a custom tag lib and "roll my own" solution (Id prefer not to). Thanks

• Does the `Expires` HTTP header needs to be consistent across multiple cold-cache requests?

  - by chakrit

  I'm implementing a custom web server of a kind. And am looking into adding an Expires header support. However, I'm a little unsure of how exactly to implement it. If multiple cold-cache requests are being made to the same unchanged resource on the server and the server returned different Expires header (say it uses relative time to calculate the exact value of the Expires date e.g. +6 hours from the request time), does that invalidate the cache on all the proxy servers in-between as well? Or is it impossible to happen (per the spec)? Does the Expires HTTP header needs to be consistent across multiple cold-cache requests?

• Per query relevance elevation for solr?

  - by plusplus

  I want to tune the relevance of solr search results on a per user basis - based on the number of times the user has clicked through a result before. Frequently hit items FOR THAT USER should rise to the top of their search results. Is there a way to provide custom boost/elevation for particular document ids on the query? I'm thinking in the order of ~100s of particular documents to elevate. The elevation should have no effect if the rest of the query doesn't find those documents. Alternatively, if this isn't possible, what is a sane way for setting up an alternative indexing approach that would make this possible? Could I add a field per user in the index to store their scores? I'm thinking in the order of 1000 users. The major drawback of that approach is the number of times a document would need to be reindexed (i.e. each time it was used by the user).

• Auto height for label or textview within table view cell

  - by Leo

  Hi Folks, I have a problem in an iPhone application. Application has a table view controller with custom table view cells. Each cell has a Label (please correct me if I need to use text view etc). I am getting text dynamically from a web service call and I don't know how long text gonna be. Now problem is that I want to adjust the table view cell height based on text I receive. How can I grow Label or TextView height withinin table view cell so it can contain all the text and in effect grow table view cell height. Does anyone know how to handle this kind of design problem? Thanks

• Best way to return a user-generated file, AJAX or Forms?

  - by Bill Zimmerman

  Hi, I'm new to web programming, so I need some help. I am writing a custom file-creation app for my site. A user visits the page, clicks on some various options and toggles some checkboxes, and the presses a 'download now' link. I have a PHP backend which will be processing the submission, and generating a PDF file. After the user presses the download link, I want the download to start like it would for any static link. My question is: What is the best way to do this? From my limited understanding, I have a choice between using AJAX or somehow using forms to submit the data. What are the advantages/disadvantages of each? Does anyone have any good links to examples? Thanks

• LINQ to Entities and Business / Validation Rules

  - by Chris

  We have a requirement where we need to allow users to dynamically create custom reports that will run against our database and return sets of data. It would be something similar to this: http://www.marcuswhitworth.com/2009/12/dynamic-linq-with-expression-trees/ but would ultimately contain the ability to create more complicated logic. I believe LINQ to Entities might possibly allow us to do something like we're attempting to achieve. I should note that these reports are going to need to run against multiple tables. Can anyone point me in the right direction for something like this? Has anyone done anything similar with LINQ to Entities?

• When to override OnError?

  - by Ek0nomik

  I'm looking into re-working and simplifying our error handling in an application I support. We currently have all of our pages inheriting from a base class we created, which in turn obviously inherits from System.Web.UI.Page. Within this base class, the OnError method is currently being overridden, and in turn calling MyBase.OnError, and then calling one of our custom logging methods. I don't see any benefit of overriding the OnError method, and I think it would be better to let the Application_Error method in the Global.asax take care of the unhandled exception (logging it) and then the customErrors section in the config would trigger a process to redirect the user. Looking online it looks like people override this method quite frequently, but I don't see a need to and this article from MSDN makes me think the same.

• [Android SDK] Text-To-Speech addSpeech not working properly

  - by arcoraven

  Hi, I'm trying to get my Android app to play a .wav file recording of the word "Spinach Salad" whenever it sees that phrase being spoken by TTS. Here's the relevant code: spinach_salad.wav is located in /res/raw prodName = "Spinach Salad" mTts.addSpeech(prodName, "com.example.textextractor", R.raw.spinach_salad); ...and later in the code: mTts.speak("blah blah blah " + prodName, TextToSpeech.QUEUE_ADD, null); I've also tried: mTts.speak("blah blah blah Spinach Salad", TextToSpeech.QUEUE_ADD, null); and mTts.speak("blah blah blah", TextToSpeech.QUEUE_ADD, null); mTts.speak(productName_str, TextToSpeech.QUEUE_ADD, null); In both cases, I'm just hearing the TTS synthesized audio, rather than my custom .wav file. (On a related note, the last chunk of code sometimes speaks out of order, saying the second line before the first).

• SQL 2005 w/ C# optimal "Paging"

  - by David Murdoch

  When creating a record "grid" with custom paging what is the best/optimal way to query the total number of records as well as the records start-end using C#? SQL to return paged record set: SELECT Some, Columns, Here FROM ( SELECT ROW_NUMBER() OVER (ORDER BY Column ASC) AS RowId, * FROM Records WHERE (...) ) AS tbl WHERE ((RowId > @Offset) AND (RowId <= (@Offset + @PageSize)) ) SQL to count total number of records: SELECT COUNT(*) FROM Records WHERE (...) Right now, I make two trips to the server: one for getting the records, and the other for counting the total number of records. What is/are the best way(s) to combine these queries to avoid multiple DB trips?

• Put logic behind generated LinqToSql fields

  - by boris callens

  In a database I use throughout several projects, there is a field that should actually be a boolean but is for reasons nobody can explain to me a field duplicated over two tables where one time it is a char ('Y'/'N') and one time an int (1/0). When I generate a datacontext with LinqToSql the fields off course gets these datatypes. It would be nice if I don't have to drag this stupid choice of datatype throughout the rest of my application. Is there a way to give the generated classes a little bit of logic that just return me return this.equals('Y'); and return this==1; Preferably without having to make an EXTRA field in my partial class. It would be a solution to give the generated field a totally different name that can only be accessed through the partial class and then generate the extra field with the original name with my custom logic in the partial class. I don't know how to alter the accesibility level in my generated class though.. Any suggestions?

• Cocoa Key event problem

  - by Oscar

  I'm trying to build my first cocoa application. done some iPhone developing before. I have a hard time understanding how to layout my project. i making a Pong game and my current design is to allocate an NSWindowController from my appDelegate. I then use custom view to act as paddles and ball. My problem is that i can't get the window controller to capture key events. Am i thinking wrong here? My idea is to have a controller class with all the logic, should i subclass another class for that?

• Printable Version of Google Visualizations DataTable

  - by maleki

  I have a custom routing application that takes information for a route from google maps. It then creates a Google Visualizations DataTable to hold all the steps in the route. My current problem is that in order to reduce overflow for very large routes, I have enabled paging in the options of the DataTable. This leads to a not so printer friendly version because only the portion of the data that is shown in the table will be printed. The other portions of the table are loaded dynamically by the API when you click prev and next. Is there a not so hard way to get the DataTable to be printer friendly when it comes time without sacrificing the ability to have paging enabled?

• Multithread Communication

  - by Robert

  I'm creating a WPF application that uses a custom object to populate all the controls. The constructor of that object is initiated by an EventHandler that waits for an API. The problem I'm having is when I try to access any information from that object using a button for example, it returns an error saying "The calling thread cannot access this object because a different thread owns it". I'm assuming this is because the EventHandler creates a new thread which doesn't allow the MainThread to have access to it. Any ideas on how to get around this?

• Blog engines for ASP.Net (maybe MVC) web sites

  - by J. Pablo Fernández

  I've built a web site on ASP.NET MVC and one little section of it should be a blog. I'm looking for a blog to integrate. In the worst case scenario it'd be a WordPress with a custom skin and RSS integration to the rest of the site. The best would be to have an ASP.NET MVC add-on, but I can live with ASP.NET WebForms. Do you have any recomendations on the engine? I've been checking out BlogEngine.Net and I'd like to have some other ideas to compare. Anything in particular you can point to regarding this integration?

• Best practices for extending third party databases?

  - by Eric Watkins

  I have a situation where our developers extended a Third party database (MS SQL) by adding tables, views, stored procedures, and functions. Recently when the vender issued updates to the database they dropped all of our custom objects. The question now is what are some best practices that will allow us to extend the third party database but keep our objects safe from future updates? My first thought is to create a separate database but then I’m stuck with fully qualifying all the references back to the original database which may cause issues promoting database changes from test to production.

• What is the best way of retrieving a specific post in Wordpress?

  - by Steven

  I need to retrieve a specific post to display on my websites front page. To avoid hard coding the post ID, I've added a custom property where I add the post ID. The following code displays the wanted post: (The code is within the LOOP) // Get content from specific post (in this case, Åpningstider post)) $openingHoursID = get_post_meta($post->ID, "apningstider", true); if (!empty($openingHoursID)) { $openingHoursPost = get_post($openingHoursID); $openingHours = $openingHoursPost->post_content; } else $openingHours = "Åpningstid ikke angitt"; <div class="openinghours"><?php echo $openingHours; ?></div> Is there a better / easier way? The output is striped for HTML. How can I maintain HTML?

• Issue with Visual C++ 2010 (Express) External Tools command

  - by espais

  I posted this on SuperUser...but I was hoping the pros here at SO might have a good idea about how to fix this as well.... Normally we develop in VS 2005 Pro, but I wanted to give VS 2010 a spin. We have custom build tools based off of GNU make tools that are called when creating an executable. This is the error that I see whenever I call my external tool: ...\gnu\make.exe): * couldn't commit memory for cygwin heap, Win32 error 487 The caveat is that it still works perfectly fine in VS2005, as well as being called straight from the command line. Also, my external tool is setup exactly the same as in VS 2005. Is there some setting somewhere that could cause this error to be thrown?

• CMS common Architecture

  - by Shalan

  Hi there, I know this is a weird question to ask, but I would like to know if there is any documentation/blog-article out there that explains the architecture of a Website content management system? More particularly, I am interested to learn more about how "widgets" are implemented. I can't remember which system it was that I've seen tis one, but in the "Page Layout view" it had the ability to allow the end user to select a widget (thumbnail gallery, contact form, etc) from a list, and drag and drop it onto custom areas of the page. I know that this is not directly a programming question, but please could I seek advice/feedback on this. Thanks!

• Regular Expression find a phrase not inside an HTML tag

  - by James Buckingham

  Hi there, I'm struggling a bit with this regular expression and wondered if anyone was about to help me please? What I need to do is isolate the 1st phrase inside a string which is NOT inside an HTML tag. So the examples I have at the moment are: This is some test text about ITS for the ITS department. Also worth mentioning ABS as well I guess.ITS, ... and ... This is some ITS test text about ITS for the ITS department. Also worth mentioning ABS as well I guess So in the first example I want it to ignore the wrapped ITS and give me the ITS at the end of the 1st sentence. In the second example I want it to return the ITS at the start of the 2nd sentence. The aim is to replace these with my own custom wrapped acronym tags in a ColdFusion application I'm writing. Thanks a lot, James

• parse/collator for php

  - by dramatic

  I'm pretty much a newbie at php (at the "install an app and try to tweak it a bit" stage). Is there a tool anywhere which can take a script which is spread over many files and show you all the code which is processed (for a given set of arguments passed to the script) in a single output? For example, I want to make a call to zen cart from a script in a different language, which returns a category listing without any surrounding page. So I want to be able to trace what the actual process is to generate that then strip off all the unwanted bits to create a custom script.
