Just a bit of background: I'm one of a group of FORTRAN programmers, looking
to switch to C++. We are trying to write a few simple examples to
demonstrate the power of the language to our manager, so he will send us all
on a conversion course.
One of many reasons is that our code is littered with examples of:
SUBROUTINE PRINT_ITEM(ITEM, ITEM_TYPE)
IF (ITEM_TYPE .EQ. SQUARE) THEN
CALL PRINT_SQUARE(ITEM)

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...

I'm working with the new ASP.NET AJAX Control Toolkit. I have a map that
has several key areas (hot spots) where when the user hovers over them, I
want to pop up a small window with information in it (text, graphics,

asp:circlehotspot control, but that only allows me to have a single hotspot.
What I want to do is create a new custom control that derives everything

I have some classes defined in shapes.h and use them like this:
const IShape* rectangle = new Rectangle(10.0, 20.0); // width, height

I took a C# class as an elective and received an incomplete in it and
am desparate for help. I have two assignments left (arrays and
inheritance) and would gladly pay anyone that can assist me with
this.
I want you to know that I'm a 41 year old mother of three boys (ages
9, 7, and 2) and have done my very best to muddle through this
course. Sadly, my old brain is not equipped to handle it. LOL

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

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...
