I've done some C++ and Java in the past, and have recently learned
a fair amount of Python. One thing I still really don't get though
is the difference between class methods and instance methods. I
guess I'll try to narrow it down to a few specific questions, but
any further input offered on the subject is greatly appreciated:
1. Are all of my class's methods supposed to take 'self' as their
first arg?
2. Am I then supposed to call...

I'd like to create a "custom output facility". In other words, I want
an object whose use is similar to std::cout/std::cerr, but offers more
flexibility. Instead of simply writing the parameter to stdout/stderr,
I'd like it to write to stdout, to a file, and/or call a logging
function.
So my output function might look something like this:
OutputFacility& OutputFacility::put(const std::string& s) {
cout << s; // print to stdout

I have a .net client/server application using remoting, and I cannot get the
custom exception class to pass from the server to the client. The custom
exception is derived from ApplicationException and is defined in an assembly
common to the client and server components. The custom class merely defines
three (3) constructors -- the null constructor; one with a string parameter;
and one with a string and innner exception parameter -- that...

In my quest to create a derived edit control in ATL that will go into an
application that will hopefully make me some money one day, I have decided to
try to devise a custom licensing scheme for it. I will describe it and would
like to see what people think and how it can be improved if possible please.
My aim is not to prevent it from being used in design mode / OK in run mode,
but to have a *relatively simple* method of making sure that...

Does anyone know if its possible to pass parameters or the values of
Request.QueryString from a web page to a custom control class? I'm using
a C# Web Application. For Example I have Web Page1 which has to

Parameter # 1 dbid and Parameter # 2 reportid.
I know that I can access the values of the parameters from the code

This is a long one, so I'll summarize:
1. What are your opinions on raising an exception within the
constructor of a (custom) exception?
2. How do -you- validate arguments in your own exception constructors?
I've noticed that, f.ex., ArgumentException accepts null arguments
without raising ArgumentNullException. Obviously, if nothing is to be
supplied to the exception constructor, the default constructor should

When I try to serialize an instance of the LocationCell below (note Building
field) I get an error in the reflection attempt. If I remove the _Building
field it serializes fine. I tried renaming Building._Name to Building._BName
in case the duplicate name was the issue, but that didn't help.
Is there a native way to serialize nested objects, or will I have to write
my own?

I was looking at a page that showed how to set up a custom event and it
seems to work ok. But I am not sure how I would use it. How would I
subscribe to it. There is actual action (such as pressing a button or
changing text in a textbox).
It gets set up and on the user control on my web page I can see the event
from intellisense. So it seems to be set up, but I am trying to get an easy
example of how I would now use this event.

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...
