I am working on this project and I need some help/pointers/comments to
get me started, I am stuck.
The program will be used to store information in an array while it is
running.
I need to store objects of my classes Person(superclass),
Student(inherit Person), Teacher(inherit Person) in that array.
The name will be the unique key. These classes are all working ok. I
want to be able to add, remove, find etc. objects.
To all of this, I...

I need to write an new class derived from the list class.
This class stores data in the list to the disk if an object
that is added to the list is over 1K in size.
What methods of the std stl list class must Ioverride in order for this
to work?

I use a mutex to disallow starting a second application instance. This
did not work in a release build until I made it static member of my
MainForm class.
In a debug build, first instance got ownership, second did not and
terminated. In a release build, the second instance *also* got
ownership. I "fixed" it by making the mutex a static member of my
MainForm class.
Did the garbage collector eat my mutex because it is not referenced

Ok, after three C# books, (C# How to Program, Programming in the Key

tried everything to make a certain form function correctly. I am
trying to learn C# after playing around for a bit with procedural
programming with PHP, not OOP, and believe I have learned quite a bit
in three weeks, just not enough to accomplish this one task.
If anyone has a bit of free time and...

Hi,
Can someone recommend a VB.NET book for an experienced VB programmer?
I have extensive experience in programming in VB, but lately I decided to
try VB.NET too. I think I have pretty good hold of this new language and
framework now.
I was wondering if someone can suggest a good (and cheap) book for me for an
intermediate programmer. Some book which has ADO.NET, web services and all

Hello,
I'm currently developing a web service that retrieves data from an employee
table. I would like to send and retrieve a custom employee class to/from the
webservice. I have currently coded the custom employee class and have built
it as a separate library (employee.dll). This employee.dll is being
referenced by both the web service and the windows application.
I face the following problem when I send this class to the webservice.

We are having a lot of trouble with problems relating to failures relating
to 'The located assembly's manifest definition with name 'xxx' does not
match the assembly reference" but none of us here really understand how this
could be an issue. The assemblies that the system is complaining about are
ones that we build here and we're not changing version numbers on anything.
The errors come and go with no apparent rhyme or reason.

I have this situation:
myEXE <needs< DerivedClass <which needs< BaseClass
Meaning, myEXE is using a type defined in DerivedClass, which inherits
from BaseClass. I include a reference to DerivedClass in myEXE, which
gives this error:
The type 'BaseAssembly.SomeClass' is defined in an assembly that is not
referenced. You must add a reference to assembly 'BaseAssembly,

I tried for an hour to find some reference to concrete information on
why this particular inheritance implementation is a bad idea, but
couldn't. So I'm sorry if this has been answered before. Here's the
scenario:
We have a base class with all virtual functions. We'll call this the
Animal class. We then make two classes Fish and Bird that both inherit
from Animal. In the program, we have a single array of Animal pointers
that will...

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...

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.

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...
