• Are there any drawbacks to using helper :all in Rails

  - by Rob Jones

  In Rails 'helper :all' makes all your helpers 'available' to all your controllers. This is concise and convenient, but does it have any memory and/or performance implications compared to explicitly calling the helpers that each controller actually needs? It's unclear form the docs whether using it involves 'require'ing all those files, or whether autoload is being used. I can't tell from the source in the Rails framework docs. thanks

• Using Helper $time->niceShort with german settings in CakePHP 1.2

  - by nolandark

  I want to use the CakePHP Helper "time" and his method niceShort to transform a date into a nice, easy to read one. Instead of the english default transformation I want to use a localized version (in my case: "german") but I don't know where to set this. How can I localize this method? echo $time->niceShort($comment['created']);

• Html helper to show display name attribute without label

  - by Pedre

  I have this: [Display(Name = "Empresa")] public string Company{ get; set; } In my aspx I have: <th><%: Html.LabelFor(model => model.Company)%></th> And this generates: <th><label for="Company">Empresa</label></th> Are there any html helper extensions to only show the display attribute without label, only plain text? My desired output is this: <th>Empresa</th> Thanks! EDIT I tried DisplayFor or DisplayTextFor as suggested, but they are not valid because they generate: <th>Amazon</th> They return the value of the property... I want the name from the Display attribute.

• Testing C++ program with Testing classes over normally used classes

  - by paultop6

  Hi Guys, This will probably be a bot of a waffly question but ill try my best. I have a simple c++ program that i need to build testing for. I have 2 Classes i use besides the one i actually am using, these are called WebServer and BusinessLogicLayer. To test my own code i have made my own versions of these classes that feed dummy data to my class to test it functionality. I need to know a way of somehow, via a makefile for instance, how to tell the source code to use the test classes over the normally used classes. The test classes are in a different "tester" c++ file, and the tester c++ file also has its own header file. Regards Paul P.S. This is probably a badly worded question, but i dont know any better way to put my question.

• Extending mysqli and using multiple classes

  - by Mikk

  Hi, I'm new to PHP oop stuff. I'm trying to create class database and call other classes from it. Am I doing it the right way? class database: class database extends mysqli { private $classes = array(); public function __construct() { parent::__construct('localhost', 'root', 'password', 'database'); if (mysqli_connect_error()) { $this->error(mysqli_connect_errno(), mysqli_connect_error()); } } public function __call($class, $args) { if (!isset($this->classes[$class])) { $class = 'db_'.$class; $this->classes[$class] = new $class(); } return $this->classes[$class]; } private function error($eNo, $eMsg) { die ('MySQL error: ('.$eNo.': '.$eMsg); } } class db_users: class db_users extends database { public function test() { echo 'foo'; } } and how I'm using it $db = new database(); $db->users()->test(); Is it the right way or should it be done another way? Thank you.

• External GUI/Helper Library for Visual C++?

  - by Psychic

  I am looking for some kind of library, either open source or bought in, that provides advanced GUI components, helper functions & classes etc. It needs to be something that integrates relatively easily into Visual Studio, and should be based around C++ and Windows. Cross platform isn't needed, and can somtimes make things a little more complex and restricted than single platform, but it is still acceptable. It also needs to be up-to-date and active. There appears to be a number of 'retired' libraries that offer little or no support, so these would not be suitable, as I'm going to need help every now and then! It also needs good documentation. I know about wxWidgets but I'm wondering what other alternatives there are? At first glance, wxWidgets doesn't strike me as what I want/need, especially in the GUI area where the visual components seem striking similar to the stock components. I want more custimization! Is there much out there that meets these requirements?

• VLC helper protocol on Mac OS X

  - by Preben

  Hey everybody, I am trying to add a vlc:// helper protocol on Mac OS X. To register the protocol, I have unsuccessfully been playing around with the MoreInternet PrefPane. What I want to have in my browser is a vlc://someressource.com/audio.mp3, which should launch VLC and add http://someressource.com/audio.mp3 to the playlist (this works fine on Windows and also Linux if I remember correctly). Maybe even just have vlc://http:// so that https would also be supported. I have no idea how to achieve this. I tried making a bash script, which MoreInternet would not accept. Then I tried making an application through Automator with my Bash script embedded. That did not work either, as the Automator application has no "creator code" - whatever that is?! Can any of you guys point me in the right direction? Thanks in advance!

• Problem using js jquery helper

  - by Josh R

  hi, I am using cakephp 1.3.6 and am trying to use inbuilt js helper. I have added var $helpers = array('Js' => array('Jquery')); in my controller. In my layout, I have included the jquery files and have also included echo $this->Js->writeBuffer(); before the </body> tag. I checked if the jquery libraries correctly but trying to create a simple accordian from the jqueryui.com, it works fine. But when I try <?php $this->Js->get('#element'); $this->Js->drag(array( 'container' => '#content', 'start' => 'onStart', 'drag' => 'onDrag', 'stop' => 'onStop', 'snapGrid' => array(10, 10), 'wrapCallbacks' => false )); ?> <div="element">something</div> It does not work. I appreciate any help. Thanks.

• Type classes or implicit parameters? What do you prefer and why? [closed]

  - by Petr Pudlák

  I was playing a bit with Scalaz and I realized that Haskell's type classes are very similar to Scala's implicit parameters. While Haskell passes the methods defined by a type class using hidden dictionaries, Scala allows a similar thing using implicit parameters. For example, in Haskell, one could write: incInside :: (Functor f) => f Int -> f Int incInside = fmap (+ 1) and the same function using Scalaz: import scalaz._; import Scalaz._; def incInside[F[_]](x: F[Int])(implicit fn: Functor[F]): F[Int] = fn.fmap(x, (_:Int) + 1); I wonder: If you could choose (i.e. your favorite language would offer both), what would you pick - implicits or type classes? And what are your pros/cons?

• Using CSS Classes for individual effects - opinions?

  - by Cool Hand Luke UK

  Hey, Just trying to canvas some opinions here. I was wondering how people go about adding individual effects to html elements. Take this example: you have three types of h1 titles all the same size but some are black some are gold and some are white. Some have a text-shadow etc. Would you create separate CSS classes and add them do the h1 tag or would you create a new single class for each different h1 title type (with grouped CSS elements)? With singular class for each effect you can build up combos of classes in html class="gold shadow" but also how would you name them. For example its bad practice to give classes and id names associated to colours, because it doesn't define what it does well. However is this ok with textual CSS classes? Just wondering what others do, I know there are no hard and fast rules. Cheers.

• C# Sharp: Partial Classes

  - by dcolumbus

  This is quick confirmation question: In order to make partial classes work, I initially thought that there would be a main Class public class ManageDates and then you would create partial classes like public partial class ManageDates to extend the ManageDates class. But from some experiementing, I've come to find out that if you're going to use partial classes, each individual class must be declared public partial class [ClassName] ... Am I correct in this conclusion?

• Boolean with html helper Hidden and HiddenFor

  - by Martin

  What's up with this?

• Searching for known Team Development helper tools

  - by John

  Hello, My team is small, only two programmers.We both share one source ,but we live in different places.The problem is that Meanwhile I make changes on our project,the other team worker makes changes as well.It's very hard to write down every change,at least for us. When we decide we've made an important change,we contact each other sending the whole project's source. This is not good,because: The files sent from one do not contain the changes that the other worker has been working on meanwhile. We host the source on free servers,thus makes it possible for other to see the files.It will be VERY much better if only few(those that are changed) files are being uploaded rather than the whole project. My question: Are there any tools that could make our lives easier? Thanks in advance! EDIT: We use Delphi 2009.

• Design: classes with same implementation but different method names

  - by Dror Helper

  I have multiple classes that have similar implementation for different named methods: class MyClassX { public int MyClassXIntMethod(){} public string MyClassXStringMethod(){} } class MyClassY { public int MyClassYIntMethod(){} public string MyClassYStringMethod(){} } the methods inside the classes have similar implementation but because the method's names are different (due to 3rd party constraints) i cannot use inheritance. I'm looking for an elegant solution that would be better than implementing the same functionality over and over again.

• Json Jackson deserialization without inner classes

  - by Eto Demerzel

  Hi everyone, I have a question concerning Json deserialization using Jackson. I would like to deserialize a Json file using a class like this one: (taken from http://wiki.fasterxml.com/JacksonInFiveMinutes) public class User { public enum Gender { MALE, FEMALE }; public static class Name { private String _first, _last; public String getFirst() { return _first; } public String getLast() { return _last; } public void setFirst(String s) { _first = s; } public void setLast(String s) { _last = s; } } private Gender _gender; private Name _name; private boolean _isVerified; private byte[] _userImage; public Name getName() { return _name; } public boolean isVerified() { return _isVerified; } public Gender getGender() { return _gender; } public byte[] getUserImage() { return _userImage; } public void setName(Name n) { _name = n; } public void setVerified(boolean b) { _isVerified = b; } public void setGender(Gender g) { _gender = g; } public void setUserImage(byte[] b) { _userImage = b; } } A Json file can be deserialized using the so called "Full Data Binding" in this way: ObjectMapper mapper = new ObjectMapper(); User user = mapper.readValue(new File("user.json"), User.class); My problem is the usage of the inner class "Name". I would like to do the same thing without using inner classes. The "User" class would became like that: import Name; import Gender; public class User { private Gender _gender; private Name _name; private boolean _isVerified; private byte[] _userImage; public Name getName() { return _name; } public boolean isVerified() { return _isVerified; } public Gender getGender() { return _gender; } public byte[] getUserImage() { return _userImage; } public void setName(Name n) { _name = n; } public void setVerified(boolean b) { _isVerified = b; } public void setGender(Gender g) { _gender = g; } public void setUserImage(byte[] b) { _userImage = b; } } This means to find a way to specify to the mapper all the required classes in order to perform the deserialization. Is this possible? I looked at the documentation but I cannot find any solution. My need comes from the fact that I use the Javassist library to create such classes, and it does not support inner or anonymous classes. Thank you in advance

• MVC helper functions business logic

  - by Menelaos Vergis

  I am creating some helper functions (mvc.net) for creating common controls that I need in almost every project such as alert boxes, dialogs etc. If these do not contain any business logic and it's just client side code (html, js) then it's ok. My problem arises when I need some business logic behind this helper. I want to create a 'rate my (web) application' control that will be visible every 3 days and the user may hide it for now, navigate to rate link or hide it for ever. To do this I need some sort of database access and a code that acts as business logic. Normally I would use a controller for this, with my DI and everything, but I don't know where to put this code now. This should be placed in the helper function or in a controller that responds objects instead of ActionResults?

• multiple classes with same methods - best pattern

  - by Tony

  I have a few classes in my current project where validation of Email/Website addresses is necessary. The methods to do that are all the same. I wondered what's the best way to implement this, so I don't need to have these methods copy pasted everywhere? The classes themselves are not necessarily related, they only have those validation methods in common.
