Hi, Is it possible to writed Sealed classes in C++ . i.e. there is no sealed/final keyword in C++, but is it possible to achieve the same effect? i.e. deriving from a sealed class is an error and the compiler should flag it as such. Thanks Bharat Karia

Why C# doesn't support sealed methods for base classes?

by: Néstor Marcel Sánchez Ahumada | last post by:

In a method declaration the 'sealed' keyword must be used with the 'override' keyword to avoid further overriding. Thus it can't be used in base classes. Why? This would be a good enhancement for C# 3.0? Any comments? Néstor

"All public methods should be virtual" - yes or no / pros & cons

by: Ken Brady | last post by:

I'm on a team building some class libraries to be used by many other projects. Some members of our team insist that "All public methods should be virtual" just in case "anything needs to be changed". This is very much against my instincts. Can anyone offer some solid design guidelines for me? Thanks in advance....

sealed method question.

by: avnrao | last post by:

Hi, I am curious about how to write C# class with this requirement : I want to make one of the methods of the class to be non overridable in derived classes. I cannot use sealed because sealed keyword on a method should also have override keyword. My class here is the master class. Consider a class Master with 2 methods

Abstract/Sealed method

by: TJM | last post by:

Hi, Is it possible to have a method sealed and abstract at the same time? MSDN states clearly that this is not allowed for classes but it does not mention it for methods. I tried with a simple example and the compiler would not allow me to compile, however in a recent interview, I was asked this question and the interviewer claimed that this is used in certain situations! I am baffled! Thanks,

Overriding the equals and hashCode methods

by: r035198x | last post by:

The Object class has five non final methods namely equals, hashCode, toString, clone, and finalize. These were designed to be overridden according to specific general contracts. Other classes that make use of these methods assume that the methods obey these contracts so it is necessary to ensure that if your classes override these methods, they do so correctly. In this article I'll take a look at the equals and hashCode methods. ...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
