I am looking to have a base class which provides that all inherited
classes MUST have some property, but that they can each define it as
whatever type they want. So maybe three class inherit from the base
class, each MUST have a property, but one defines it as
OracleType, one as SqlType and one as DB2Type, for example.
I know i can just declare it as Object, and then have the classes each
do typechecks on value assignment, but this is...

I am writing a VB.NET application in Visual Studio 2003. I have written a
method that handles several events, such as closing a form and changing the
visible status of a form. I have some code that applies to all these
events, but I need to have specific code execute when the form closes. The
properties for this method are sender (the originator) and e (event
arguments). I know how to get typeof (sender) to determine what form or...

All,
Is there a way to force a derived class to contain an event. I have done
this with methods (i.e. Protected MustOverride Sub Test), but can I do
something similar with an event (Protected MustOverride Event MyEvent
doesn't work for obvious reasons)?
Thanks in advance.

Hi
This must be an often encountered problem. I want to declare an abstract
class or an interface with nothing but several static constants so that I
can use polymorphism when I call each of them from my code. My stab at the
problem is shown below. Can anyone suggest what my most efficient workable
solution would be (i.e. I don't want to have to create instances of the
classes as they will only store constant information and I would...

I've got a good question about object-oriented programming, I hope I can explain it well enough. I'm creating a UserManager, which I'm going to inherit from so different applications can share common methods.
Public MustInherit Class UserManager
Public MustOverride Sub AddUser(usr as InternetUser)
End Class
Public Class InternetUser
Public username as string
End Class

In it's simplest form, assume that I have created a usercontrol,
WSToolBarButton that contains a button. I would like to eventually create
copies of WSToolBarButton dynamically at run time based on some
initialization information obtained elsewhere. Basically, I'm going to
create my own dynamic toolbar where the toolbarbuttons can change. I'm not
using the VB toolbar because of limitations in changing things like
backcolor (I can't get...

will always execuate after the system is completed...

executed before and after the...

I have created a class that has a mustoverride method. When I inherit
this class VB automatically creates the overrides function for it. I
was wondering if there was a way to have VB include a comment when it
automatically creates the method. Example "TODO: you must ........"

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

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...
