Just want to see if this is 'by design' or a bug...
I have a common List<T> defined in a base class, and the base class has a
static property to expose this list.
I wanted the derived class to add items to this list, but have the base
class hold the data and expose the property.
Problem is, however, that the derived class' static constructor doesn't get
called when DerivedClass.MyList is accessed, so the list has no members. If

I want to access the protected member hresult of the Exception class, so I
derived my own class from ApplicationException and SystemException.

In C++ one can change the access level in a derived class by the "using"
keyword. So, for instance, a public method in a base class can be made
private in a derived class. Is there any way of doing this in C# ?

hey all, got a problem here using Visual basic .net 2005
i have two pairs of base/derived classes. lets call them Base/Derived
and BaseStruct/DerivedStruct.
i want to be able to instantiate a DerivedStruct in my Derived class,
but have the instance of it be accessible from both the Base class (as
BaseStruct) and Derived class (as DerivedStruct)
this is the kind of code i'm looking to be able to use

I have a base class that must have a member variable populated by, and only
by, derived classes.
It appears that if I declare the variable as "internal protected" then the
base class *can* populate the variable, but the population is not *required*
by the derived class (which must be the case).
What would meet the requirements is if I create an abstract method in the
base class that populates the member variable. In this case the...

I have a base class with protected members (`Base`). The function `MakeBase()` is a member function of another class, that returns a `Base` object initialized with private members of this class.
Now the thing is, I want to extend the functionality of `Base` class. I do that by inheriting `Base` class by `Derived`, but then I can't use `MakeBase()` function. It all makes sense to me, but I don't seem to find an appropriate solution.
Since I...

If I pass a base class object by reference (likely does not make a
difference here that it is passed by reference) as a parameter to a
derived class member function, the member function is not allowed to
access the protected data members of the base object. This surprises
me.
Can someone explain why this is? I suspect there is a good reason and
I am just having a slow day to not come up with it myself.

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...

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...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
