I have what looks like a bug trying to generate new style classes with
a factory function.
class Animal(object): pass
class Mammal(Animal): pass
def newAnimal(bases=(Animal,), dict={}):
class C(object): pass
C.__bases__ = bases
dict = 0

I've noticed that a few ASPN cookbook recipes, which are recent
additions, use classic classes.
I've also noticed classic classes are used in many places in the
standard library.
I've been using new-style classes since Python 2.2, and am suprised
people are still using the classic classes.
Is there a legitimate use for classic classes that I am not aware of?

Hello,
in the last few days I've made my first few attempts at creating mixed C++
managed-unmanaged assemblies and looking aftwerwards with ILDASM at what is
visible in those assemblies from a managed point-of-view I've noticed that:
1) for each managed and unmanaged C function (not C++ classes) I get a
public managed static method (defined on a 'Global Functions' class) in the
generated assembly with an export name of the form...

Hello
I have a library of calculationally intensive classes that is used both by a
GUI based authoring application and by a simpler non-interactive rendering
application. Both of these applications need to serialise the classes
to/from the same files but only the GUI app needs the full range of class
methods.
Now, the rendering app needs to be ported to multiple OS's but the GUI
doesn't. In order to reduce the time/cost of porting I'd...

Hello,
My question is how to use C# to call the existing libraries containing
unmanaged C++ classes directly, but not use C# or managed C++ wrappers
unmanaged C++ classes?
Does anyone know how to do that?
Thanks.

Is the packing alignment of __nogc classes stored as part of the assembly ?
I think it must as the compiler, when referencing the assembly, could not
know how the original data is packed otherwise. Yet, in my understanding,
attributes are only __gc and __value class specific and do not apply to
__nogc classes. Is this correct ? If so, how is the packing alignment of
__nogc classes stored ?

I want to write a Mesh class using half-edges. This class uses three
other classes: Vertex, HalfEdge and Face. These classes should be
linked properly in the process of building up the mesh by calling Mesh
class functions. Let's say they point to each other like this:
class Vertex {
HalfEdge *edge;
};
class HalfEdge {
Vertex* vert;

I am writing this in a new thread to alert that I found a solution to
the problem mentioned here:

and to avoid this topic getting lost before people interested in the
problem notice it.
The important tricks to the solution are two:
1) make the custom classes take a TEMPLATE argument which defines their
BASE class
2) EMBED the custom classes in a "Traits"...

Suppose you have a couple of helper classes that are used by 2 client
classes only. How can I hide these helper classes from other
programmers? Do you think this solution is a good idea?:
class Hidden_functionality
{
protected:
// These helper classes provide some functionality that is
// only used by the client classes
class Helper1 {};

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

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,...
