Sorry if this has been discussed before (I'm almost certain it has), but
I didn't know what to google for.
My problem is, I have a class, a gtkmm widget, and I want it to serve as
a base class now, but I'm not sure if I'm taking the proper steps in
order to not break the whole class.
Are there any guidelines what I have to watch out for?
One question would e.g. be:

Hi all,
I have a site with the following architecture:
Common.Web.dll - Contains a CommonPageBase class which inherits
System.Web.UI.Page
myadd.dll - Contains PageBase which inherits CommonPageBase
- Contains myPage which inherits PageBase
Each of these classes overrides OnInit and ties an event handler

Good afternoon everyone. I'm running into a problem deserializing a stream

In my code, person is the base class and student extends it. When I

It looks like the language is trying to prevent me from doing this sort of
thing. Nevertheless, the following compiles, and I'd like to know why it
doesn't work the way it should:
public class ComponentA
{
static string s_name = "I am the root class.";
public string Name { get {return s_name;} }

I had a need recently to check if my subclasses properly implemented
the desired interface and wished that I could use something like an
abstract base class in python. After reading up on metaclass magic, I
wrote the following module. It is mainly useful as a light weight tool
to help programmers catch mistakes at definition time (e.g., forgetting
to implement a method required by the given interface). This is handy
when unit tests or...

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...

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...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
