Hi Folks!
Everytime I work with virtual and pure virtual methods I ask myself if
there is a difference between class B and class C (see below). Is it
redundant to repeat the virtual keyword in a derived class? Or is there
any difference I need to consider? I have seen both ways when I read
source code from external sources. So far I didn't find any answers in
my books or on the net.

I know how to detect .NET Framework, and I know how to re-register ASP.NET.
But is there any way to detect that ASP.NET is not registered with IIS? I
want my installation program to treat this case better than just failing to
install. I am using VS.NET Deployment project.
Thanks in advance.

Hi there,
I'm trying to write a C# application that gets information from a
machine such as operating system, memory, cpu etc. I'm using WMI for
this, and it all seems to work fine apart from the fact that
Win32_PhysicalMemory doesn't have any instances. I have therefore come
to the conclusion that I need to try and access the memory information
using the Serial Presence Detect (SPD) information on the EEPROM on the
memory stick(s)....

Hello Pythonists,
I'd like to write for myself a tiny program that counts time spent on each
virtual desktop (in GNOME). In order to do that, I need my program to
detect the current virtual desktop. I've googled for it for about one hour
and couldn't find any solution. The closest thing I found is set of
tutorials: http://www.pygtk.org/articles.html Unfortunately, none of them
answers my questions:

I have a base class, PadRcv, with virtual functions. User code
will derive from this class and possibly supply it's own functions
to override the base class virtual functions. How can I test that
a user-defined class has overriden the virtual function in the
base class?
I have code like this which compiles with gcc 2.95.4:
Attrib Implicits(PadRcv *obj){
Attrib accum = 0;

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....

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