Why are member constants available even if there are no instances of a its class?

- by flockofcode

1) Why are member constants available even if there are no instances of a its class? 2) Is the only reason why constant expressions need to be fully evaluated at compile time due to compiler replacing constant variable with literal value? 3) Since string is also an object, I would think the following would produce an error, but it doesn’t. Why? class A { const string b = “it works”; } thank you

How do I detect a text input's value and set a class with jQuery?

- by Zander

I would like to make sure if a textbox has any content at all, that jQuery can show it's parent (an <li class="hidden_dedication") element and set add a class of 'shown'. I'm pretty sure that it should be something like this, but cannot get it to work: if ($('li.hidden_dedication input').val() !== null) { $(this).parent().show().addClass('shown'); } I cannot figure it out.. any ideas? Many thanks

jQuery apply functionality only to class and parent elements.

- by kylex

I have the following list: <ul> <li class="topCurrent">One <ul> <li>One-1 <ul> <li>One-1.1 <ul> <li class="current">One-1.1.1 <ul> <li>One-1.1.1.1</li> <li>One-1.1.1.2</li> <li>One-1.1.1.3</li> </ul> </li> <li>One-1.1.2</li> </ul> </li> <li>One-1.2</li> </ul> </li> <li>One-2</li> <li>One-3</li> </ul> </li> <li>Two <ul> <li>Two-1</li> <li>Two-2</li> </ul> </li> Using the following jQuery: $("ul li ul").hide(); $("ul li").hoverIntent( function(){ $(this).children('ul').slideDown('fast'); }, function(){ $(this).children('ul').slideUp('fast'); } ); What this does is hide all of the ul below the top level ul until there is a hover over it. What I would like to do is this: If an li has a class="current" I would like that structure to be open up until the point that current is hit. It would still allow the ul below it to be displayed on a hover, as well as any other ul's, but at no point would the parents of class="current" be hidden. Suggestions? This problem has been driving me crazy. Thanks!

I have a web service defined as follows, residing in a class library: [WebService(Namespace = "http://comp.com/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService] public class SendingItems_new : System.Web.Services.WebService When I double click it, instead of going to code view, it shows the design view.

Given a PHP class would be the best and simplest way to override one or two of its methods with one

- by racl101

Here's the objective. I have a PHP class and there are one or two of its methods that I would like to override with my own. As I understand OOP (in PHP and in general) I could write a child class that extends it and overrides the functionality of the methods in question. However, I was wondering if this is the best way of achieving this task and if this is a proper use for child classes or if there is something better in PHP for what I'm trying to do.

Can a trait state if a C++ class has a default constructor?

- by Vicente Botet Escriba

Traits classes can be defined to check if a C++ class has a member variable, function or a type (see here). Curiously, the ConceptTraits do not include traits to check if a C++ class defines a default constructor or given constructor? Can traits be used to check the constructor presence? If yes, how? If not, why it is not possible?
