I find an interesting issue that one base class has only one copy for
each derived class. It looks like that one base class will be copied into
three base classes while derived class from base class is executed. It
means that three derived classes are pointed to a separated copy of base
class. I do not allow second and third copy of base class to be created,
but it must remain only first copy of base class.
It allows three derived...

Question is as in subject.
For example:
class BaseClass {
public:
void func() { do something; } // I don't want this function being
overloaded in its inherited class
};

if I have a class template declared as ff:
(BTW is this a partial specialization? - I think it is)

Hello,
i'm new to .Net (i'm using VB as language and i'm working in the
code-behind mode) and i can't solve the following problem:
I have a WebForm and want to Add a UserControl
(classname:QuestionControl) as many times as there are rows in a
DataTable (also named Questions) in a DataSet. But this UserControl is
,for reasons of structuring, not a member of the WebForm Object in
which it should be displayed, it is member of another class...

Hey all,
I'm trying to understand Master/Detail concepts in VB.NET. If I do a data
adapter fill for both customer and orders from Northwind where should that
dataset live?
What client is responsible for instantiating the orders class? Would it be
the ui layer or the master class in the business layer?
thanks,

Hi.
I have a RCW class that was generated by the VS.NET2003 IDE when I added a
COM dll reference to my project. This all works fine when I call methods on
it. My initial problem is that in ASP.NET I would like to add this to the
Session object whilst using SQLServer as the session storage. Unfortunately,
as this required the RCW class to be serializable, this won't work, and
throws an exception saying you can't Serialize the Session...

I have a .aspx file and it's src. I also have a third file, a class
that the src references. Everything is in the same directory/folder.
Everything has the same namespace. How do I reference the class in my
c# .src file? I don't believe this is an ASP.NET question, but a OOP
C# question, thus my post here.
I have searched and I thought it was with:
using FilterSQL; //the name of my class
using reports.FilterSQL; //name of...

I'm working with GUI messaging and note that MFC encapsulates
the message loop inside of a C++ class member function. Is this
somehow inherently less robust than calling the message loop
functions within main? (It just doesn't "feel" right to me).
Example 1:

Suppose there is the following class structure.
class S {...}
class A : S {...}
class B : S {...}
class A1 : A {void m(){...}}
class B1 : B {void m(){...}}
class B2 : B {...}
Just to clarify the issue. A1 and B1 share a
method (void m() ) AND B2 doesn't have that

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
