should_receive in RSpec
- by gmile
As far as I know, should_receive is applied only to mock objects. What I want is to check, if a certain Class (not object) received a certain message, like:
User.should_receive(:all).once
How do I do that?

Visual Studio C#: Why is a "using" directive insufficient for some libraries?
- by JYelton
Scenario: I needed to add HttpUtility to my project, and I started by adding "using System.Web" to my collection of using directives. However the HttpUtility class would still not resolve, and I discovered (via this question) that I needed to add a reference to my project. Question: Why do I need to add a reference to this library when for most other classes a "using" directive will suffice?Read the article

Hello, To "simulate" instances from class diagrams I am using USE But I find very frustating to create instances. I am looking for similar tools like this one. I really like USE, but GUI is painfull.

- by pointlesspolitics
In MSDN documentation, many .NET classes methods (like ArrayList ) mentioned that "Supported by the .NET Compact Framework".

Any help is much appreciated :)Read the article

How do I create and read non-global variables that aren't destroyed at end of function?
- by Paul Reilly
I am attempting to code some plugins to use with MIDI sequencers but have hit a stumbling block. I can't use global-scope variables to store information because multiple instances of the .dll can exist which share memory. How do I create a class (for re-usability purposes in other plugins) containing 2 dimensional array and other variables the content of which is to be shared between functions? If that is possible, how would I read and write the data from the function in the framework where I do the processing?Read the article

jQuery .hasClass method to omit effect

I've created a simple background effect for some tabs on a page but don't want that effect to fire if the tab has the class 'current'. I presume there is a way to do this using .hasClass Here's what I'm using for the effect: $('ul.htabs a').mouseover(function(){ $(this).stop().animate( {backgroundPosition:"(0 -810px)"}, {duration:150}, {easing: 'easeOutCubic'}) }).mouseout(function(){ $(this).stop().animate( {backgroundPosition:"(0 -806px)"}, {duration:150}, {easing: 'easeInCubic'}) });Read the article

Are classes in Python in different files?
- by Asaf
Much like Java (or php), I'm use to seperating the classes to files. Is it the same deal in Python? plus, how should I name the file? Lowercase like classname.py or the same like ClassName.py? Do I need to do something special if I want to create an object from this class or does the fact that it's in the same "project" (netbeans) makes it ok to create an object from it?Read the article

Is passing a struct value to a method by-reference in C# an acceptable optimization?
- by Arc
Say I have a struct: struct MyStruct { public int X public int Y } And a method in some class that is iterated over many times elsewhere: public bool MyMethod( MyStruct myStruct ) { return ... } Is changing the MyMethod signature to the following an acceptable optimization? public bool MyMethod( ref MyStruct myStruct ) If so, how much of an advantage would it really be? If not, about how many fields would a struct need for a big enough advantage using ref this way?Read the article

Python: How should I make instance variables available?
- by swisstony
Suppose I have: class myclass: def __init__(self): self.foo = "bar" where the value of foo needs to be available to users of myclass. Is it OK to just read the value of foo directly from an instance of myclass? Should I add a get_foo method to myclass or perhaps add a foo property? What's the best practice here?Read the article

Learning Recommendations? Classroom? Tutorials?
- by cdg
Hi there. Does anyone have any recommendations for a class (online) or tutorial that teaches android programing for dummies? It's frustrating knowing exactly what you want to do and no idea how to do it. Something that uses basic language and explains each line in detail to help a person remember how to do it later. Any suggestions would be great. Thanks.Read the article

Purpose of PHP constructors
- by Bharanikumar
Hi, I am working with classes and object class structure, but not at a complex level – just classes and functions, then, in one place, instantiation. As to __construct and __destruct, please tell me very simply: what is the purpose of constructors and destructors? I know the school level theoretical explanation, but i am expecting something like in real world, as in which situations we have to use them. Provide also an example, please. RegardsRead the article
