I'm starting to develop an application in Python running the interpreter
from C, i've got callbacks and stuff setup (was pretty pleased with that)
and i'm starting to get my head around the reference counting but i've hit a
snag. I'm creating objects within python then linking them to their C
counterparts, what i want to do now is directly access the python class
variable objects from C. Basically i have the python class object as a C...

Hello all,
I have recently been porting code from Linux to cygwin and came across
a problem with static const class members (discussed below). I am
seeking to determine whether I am programming non-standard C++ or if the
problem lies elsewhere.
To summarize static const class members are not being accessed properly
when accessed from a DLL by another external object file (not within the
DLL). It only occurs when the static const...

Sorry about the big code dump. I tried to get it down to the minimum
required to demonstrate the problem. Although this is all done with GNU, I
believe the problem I'm having may be more general. Someone on the SuSE
programming mailing list suggested my problem is that I'm trying to execute
a function (I assume he meant the constructor) at compile time. The same
source code compile if I don't try to split it up into separate libraries.

Hi,
I have a C# class libary (Class1) which is inherited by another class in a
Windows Forms app. I want this other class to implement some, but not all of
the features of the base class. How can I completely hide (within the IDE)
the members of the base class library i.e. only expose those members that I
want exposed? I've tried some methods gleaned by googling for "hiding base
class members" which suggested using things like "new" and...

I'm having problems using static members of a class (largely HANDLEs of various sorts) as static class members of a class. It compiles OK but the linker complains of unresolved external symbol. Declaring them as just normal globals or member variables doesn't cause the said problem

Is it true that if we don't specify a default constructor for
our class, then the C# compiler provides us with its own
that zeroes (or assigns default values) to the data members?
I wrote a no-parameter constructor for my class with an
empty function body. I then instantiated an object and tried
printing its values, amazingly the members were already initialized.
But how is this possible if I have not included any code for doing
so. 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...

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...
