Hello all...
In my code below, the Notify Constructor and Destructor is getting
called twice and it appears that a new Notify object is created on the
2nd call. The 2nd call is caused by this line below: pNotify = new
EMAILnotify; that lives in the Notification Constructor.
One theory is that the Notify base class is not completely constructed
prior to using it in the Notification Constructor code: pNotify = new
EMAILnotify;

I'm fairly new to C++ and VC++, but for the most part it seems to do most of
the same things that can be done in Java, with just some syntactic and
structural adjustments. However, one thing I haven't been able to figure out
is how to call one constructor from another within a class. It's easy enough
to call the base class's constructor from the derived class, but that's not
what I'm trying to do.
For example, in Java (or J#) it's easy...

Hello,
If I have a class that has virtual but non-pure declarations, like
class A{
virtual void f();
};
Then is A still an abstract class? Do I have to have "virtual void
f() = 0;" instead? I think declaring a function as "=0" is the same

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

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...
