If i inherite a queue class into my class, and do an override of the enqueue
member, how would i then go about actually doing an enqueue of an item? I am
a little confused on this one... does over ride just add aditional code
ontop of the current class or completely over ride it in vb? I am use to C++
this is the first inherited thing I've done in VB.NET... I'm a little unsure
of diffrences, could someone explain this to me some? thanks!

Hi all,
If I derive a class from another one because I need a few extra
features, is there a way to promote the base class to the derived one
without having to make copies of all attributes?

def __init__ (self, base_object):
# ( copy all attributes )

I need to make software engineering decision to do with using a
derived data type in a container class. So for example, if I have an
Edge class, and I want to make a Edge object which contains two
NumberVertices instead of Vertices, I can either just use a non-
templated Edge class which stores pointers to my NumberVertices and
leave it up to the programmer to cast back again to NumberVertex (this
type of casting only works with...

Using VS 2003, I am trying to take a class that I created to create new
variable types to handle nulls and track changes to standard variable types.
This is for use with database variables. This tells me if a variable has
changed, give me the original and current value, and whether the current
value and original value is/was null or not.
This one works fine but is recreating the same methods over and over for
each variable type.

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...

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...
