I wrote an abstract base class from which I've derived a few other
classes. I'd like to create a base class array where each element is
an instance of a derived object. I can create a base class pointer
which points to an instance of a derived class, but when I pass that
base class pointer into a function, it can't access the derived
object's public functions. Although, the base class pointer does call
the appropriate virtual function...

Please help
I don't know if this is possible but what I would really like to do is

an error occurs.
Any help would be much appreciated.

Hi Folks,
Just wondering if there is any real need to convert an application from 2000
or XP to 2003, if the application is not going to grow or change. Ive had a
couple people ask about it (converting to 2003) but I can't see a reason
they should other than their IT manager want's to buy new stuff.
Any help or opinion would be great
Thanks!

We are running an Access 2000 MDB with a SQL 7 back end. Our network guy is
upgrading to Windows Server 2003 and wants to upgrade Office and SQL Server
at the same time. We're moving to SQL Server 2005, and, since he already has
licenses for Office Pro 2002, he wants to upgrade to that.
I've been saying that we need to upgrade to Access 2003, not 2002, even if
Office is kept at 2002. We are also looking to do a fair amount of...

I am a little confused about what I need to do here. I created four separate classes (Circle, Rectangle, Square, and Triangle) that each calculate their own area and perimeter via user input.
Now I have to extend the Shape class with Circle and Rectangle classes, first. Then, I have to extend Rectangle with Square and Triangle classes.
Was I supposed to calculate the area and perimeter of the four shapes in the Shape class, or did I do it...

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 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...
