Hi,
I need to traverse the methods defined in a class and its superclasses. This
is the code I'm using:
# An instance of class B should be able to check all the methods defined in B
#and A, while an instance of class C should be able to check all methods
#defined in C, B and A.

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...

Hi,
I'm learning C++ as a hobby using The C++ Programming Language : Special
Edition by Bjarne Stroustrup. I'm working on chpater 13 exercises that
deal with templates. Exercise 13.9 asks for me to turn a previously
made String class that deals with char's into a templated String class
that uses the template parameter C instead of char. I thought it would
be fairly simple to do this exercise, but I encoutered many errors for
my...

I find an interesting issue that one base class has only one copy for
each derived class. It looks like that one base class will be copied into
three base classes while derived class from base class is executed. It
means that three derived classes are pointed to a separated copy of base
class. I do not allow second and third copy of base class to be created,
but it must remain only first copy of base class.
It allows three derived...

Hi all,
I have a site with the following architecture:
Common.Web.dll - Contains a CommonPageBase class which inherits
System.Web.UI.Page
myadd.dll - Contains PageBase which inherits CommonPageBase
- Contains myPage which inherits PageBase
Each of these classes overrides OnInit and ties an event handler

I have a set of classes that each have an enumeration in them, and based on
dynamic input I need to access a different enumeration. For example
Three classes Class_A, Class_B, and Class_C that all have a different
enumeration in them called Properties. I want to basically have a variable
The_Class that I can dynamically point to either Class_A, Class_B, or
Class_C and then do The_Class.properties to get the correct enumeration.

For Python developers around.
>From Python 2.5 doc:
The list of base classes in a class definition can now be empty. As an
example, this is now legal:
class C():
pass
nice but why this syntax return old-style class, same as "class C:",
and not the new style "class C(object):" ?

Diehards,
I developed a template matrix class back around 1992 using Borland C++ 4.5
(ancestor of C++ Builder) and haven't touched it until a few days ago. I
pulled it from the freezer and thawed it out. I built a console app using
Microsoft Visual C++ 6 (VC++) and it worked great. Only one line in the
header file had to be commented out.
I built a console app using Borland C++ Builder 5. The linker complained of
references to...

I had a need recently to check if my subclasses properly implemented
the desired interface and wished that I could use something like an
abstract base class in python. After reading up on metaclass magic, I
wrote the following module. It is mainly useful as a light weight tool
to help programmers catch mistakes at definition time (e.g., forgetting
to implement a method required by the given interface). This is handy
when unit tests or...

class so that I can load data from any XML file without having to
write a parser for each one.

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
