Do you know a js library that implements a generic Iterator class for collections (be it Arrays or some abstract Enumerable) with a full set of features, like the Google Common or the Apache Commons?
HI,
In singleton class we are declaring constructors as private. Is it possible to give as protected.
If giving as protected is it beneficial.
Whats the advantage or disadvantage of private over protected
I'm making a database program. I want the user to be able to define their own columns, as many as they want. How would I then define each record in its class file?(Since the properties would be different user to user)
EDIT:
It's part of a school assignment-it's going to hold different scores and the likes for the teacher for different students they can add, but they will also be able to add a new assignment, test(a column) .
What's the best way of parsing the folowing rss feed item into a C# class.
<item>

<fh:Airline AirlineCode="EI" Name="Aer Lingus" />
</fh:FlightHistory>

I need recommendations for an established and maintained cURL wrapper library/class to use with cURL in Php.
It wouldn't hurt if there was some documentation with it, but its not a must have.
Thanks
Hi,
I want to exclude certain fields in the init function of a modelform depending on a parameter passed in, how do I do this? I know I can add exclude fields using the meta class of a model form but I need this to be dynamic depending on the variable passed in.
Thanks
I am having some trouble getting this simple code to work:
class CreateUserView
{
public:
CreateUserView(void);
~CreateUserView(void);
UserController* controller;
void showView();
string name;
string lastname;
string address;
string email;
string dateOfBirth;
};
All i need is to set these attributes in the implementation with getline().
CreateUserView::CreateUserView(void)
{
}
void CreateUserView::showView()
{
cout << endl << " New User" << endl;
cout << "--------------------------" << endl;
cout << " Name\t\t: ";
getline(cin, name);
cout << " Lastname\t: ";
getline(cin, lastname);
cout << " Email\t\t: ";
getline(cin, email);
cout << " ===============================" << endl;
cout << " 1. SAVE 2.CHANGE 3.CANCEL" << endl;
cout << " ===============================" << endl;
cout << " choice: ";
int choice;
cin >> choice;
cin.ignore();
controller->createUser_choice(choice);
}
I keep getting this "Access violation reading location" error at this line:
getline(cin, name);
what's the best way of assigning a value to an std::string attribute of a class?
even name = "whatever" is throwing that error!!
thanks
Hi,
I have the following member of class foo.
foo &foo::bar()
{
return this;
}
But I am getting compiler errors. What stupid thing am I doing wrong?
Compiler error (gcc): error: invalid initialization of non-const reference of type 'foo&' from a temporary of type 'foo* const'
How do we populate\retrieve information from\into multiple forms in same action class in Struts2 ? With ModelDriven approach, action is tied to one form. With ScopedModelDriven interceptor jsp becomes dirty as one has to write model.property to access form properties. Is there a better way of doing it?
Hello,
gcc 4.4.1 c89
I have the following code and I get a warning:
unless class storage specifier in empty declaration
static enum states
{
ACTIVE,

}
However, if i remove the static keyword I don't get that warning.
I am compiling with the following flags:
-Wall -Wextra
Many thanks for any suggestions,
Hi, I'm relative new to C++ and my background is in Java. I have to port some code from Java to C++ and some doubts came up relative to the Object Java's class. So, if I want to port this:
void Algorithm::setInputParameter(std::string name, Object object) { ..... }
I believe I should use void* type or templates right? I don't know what's the "standard" procedure to accomplish it.
Thanks
This compiles well for me - However other people on a different thread are saying that protected classes cannot be declared in c# at top level
Is that the case?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
protected class CsvReader
{
}
}
I'm really banging my head onto this one. I can't make the Custom Configuration to work with NUnit. It kept on failing to read the configuration file.
I followed carefully this article: http://devlicio.us/blogs/derik_whittaker/archive/2006/11/13/app-config-and-custom-configuration-sections.aspx
placed the references in the Unit test class App.Config, still everything failed.
Is there some sort of a magic setting to do here?
intrusive_ptr requires intrusive_ptr_add_ref and intrusive_ptr_release to be defined. Why isn't a base class provided which will do this? There is an example here: http://lists.boost.org/Archives/boost/2004/06/66957.php, but the poster says "I don't necessarily think this is a good idea". Why not?
How can I convert a Class to byte array in C#. This is a managed one so the following code is failing
int objsize = System.Runtime.InteropServices.Marshal.SizeOf(objTimeSeries3D);
byte[] arr = new byte[objsize];
IntPtr buff = System.Runtime.InteropServices.Marshal.AllocHGlobal(objsize);
System.Runtime.InteropServices.Marshal.StructureToPtr(objTimeSeries3D, buff, true);
System.Runtime.InteropServices.Marshal.Copy(buff, arr, 0, objsize);
System.Runtime.InteropServices.Marshal.FreeHGlobal(buff);
Thanks
in java you can create an object directly after the property field like this:
but it seems not working for php:
class Test {
public $object = new Object();
}
you have to create it in the __construct() and assign it to the property?
thanks
I have a C# function that does some processing and needs to return figures about what it has processed, success, failure, etc.
Can anyone tell me if there are any standard framework classes that will handle this (for example, number of records processed, number successful, failed, etc) ?
Alternatively, can anyone say how they usually handle this? Is the best way to create a class, or to use out parameters?
Hi, I believe this is a tough one...
I'm trying to create a collection of variable binding in a class.
It is intended to look something like this:
Dim x as integer, s as string
Dim c as new VBindClass
x = 1
s = "Hello"
c.Add x, s
Debug.Print c.value(x) '= 1
Debug.Print c.value(s) '= "Hello"
Is there some function that allow us to retrieve a unique ID for a given variable and also get/set based on variable?
I can't find any good documentation on what the concept of a Class Loader is in the .NET Framework? What is it? Where can it be found? Does anyone know?
Hello,
To get the type of a class called myClass I do this
Type myType = (typeof(myClass))
How about, instead of having myClass, I've rather the instanceOfMyClass? How do I get the type?
Let's say I've this
Contact contact = new Contact();
If I want to know which type is contact, how do I do it
Thanks for helping
