I have looked at many object-oriented programming frameworks out there
for C. Though the ideas presented are intriguing, and I've used some
of them in my own work, they all suffered some drawback or another.
I have created a new method of doing OOP with C, something that fits
my needs particularly well. I haven't encountered anything else like
it, so I'm tossing it out to the Internet for comment.

Hi,
i have a class that is derived from System.Web.UI.Page, and this is the
class i use in my application as PageBase.
all other page classes are deriverd from my PageBase instead of the original
System.Web.UI.Page in order to have common checks in the page base.
i make securirty checks in the page base page_load event.
if the security fails, i can do whatever i want before the "real" / derived
page gets to be executed.

I have simple class hierarchy (without multiple inheritance):

Is it ok to cast void(Base*) to void(Derived*) if I know exactly what I
will pass Derived* as a parameter?
I want to register different handlers for different types using

I have recently upgraded a web project from ASP.NET 1.1 to ASP.NET 2.0,
and now the event handlers no longer work, due to the event handlers
being defined in base classes.
To start a bit of background, below is a simplified example, but the
same design pattern is used for many other pages:
In the ASPX file a button is defined:
<asp:Button Runat="server" Text="Login" id="btnLogin"></asp:Button>

Hi Everyone,
I have a few form classes that inherit from the same base class. The main
reason that this is done is that some event handlers are common between
these classes and I was trying to save time and not have to put a event
handler in every form class.
The base class has an event handler for Edit.Enter and Edit.Leave so that it
can turn the Edit menu items on and off.

KeyDown won't work KeyPress fails KeyDown not seen
inspired by a poster here:http://tinyurl.com/62d97l I found some
interesting stuff, which I reproduce below for newbies like me.
The main reason you would want to do this is for example to trigger
something from an OnPaint event without resorting to boolean switches--
say if a user presses the "M" key while the program is Painting, the
user gets the PaintHandler to do something else. ...

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....
Now, this would greatly impact the work of software developers. The idea...
