Prefer composition to inheritance (can't recall which text I stole that
line from) is one of the fundamental tenets thats engrained in my mind.
Having said that inheritance requires careful thought. To compound
things, when dealing with inheritance 'virtuality' can only be
experienced through base pointers to derived.
There are ocassions though that I dont need a (particulay) 'virtual'
function in base. In which case I'll have to...

Recently, I tried and did a poor job explaining an idea I've had for handling
a particular case of implementation inheritance that would be easy and obvious
in a fully OOP language, but is not at all obvious in VBA which lacks
inheritance. I'm trying the explanation again now.
I often find cases where a limited form of inheritance would eliminate
duplication my code that seems impossible to eliminate otherwise. I'm getting

Hi,
I just read the pattern "Design and Implementation Guidelines for Web
Clients" from MSDN.
Here is my question. In chapter 3,
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpag/html/diforwc-ch03.asp ,
the article mentions using page inheritance to maintain common page layout.
We currently use page inheritance approach to segment the function areas. In
each function area, there is a base page to provide the common...

1. I have a Base class that has a certain amount of functionality.
2. Then I have a CodeSmith generated class that inherits from the Base class
and adds functionality.
3. Since I want to be able to re-generate the classes on level 2 I have a
3rd level that inherits from them and implements specific hand coded
methods.
4. My colleague asked me to create a 4th level class that inherits the 3rd
level class so he can write custom...

why doesn't .NET support multiple inheritance?
I think it's so silly!

I've been working on a project to help myself better understand how inherited
classes work. I think I've learned more about classes by doing this than any
other effort I've made.
I've tried to create a simple problem by creating a class named TestThis
that inherits System.Windows.Forms.Form and then adding one shared procedure
to this. I set the form to inherit TestThis instead and it gets everything
plus the one procedure that I've...

Hi to all, I'm facing a problem in a particularly complex inheritance
hierarchy, and I'd like to know what the standard says about it and if my
compiler is correct in what it does.
I have two consecutive layers of diamond-shaped inheritance; the first layer
is declared as using virtual inheritance, while the second one is declared
as *not* using it.
This is what I'd like to have:

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
