For a variety of reasons, I'm interested in putting together some
code that will allow me to created structures out of nested classes,
something like:
class class1:
def methA(self):
print "Some code here"
class class2:
propA = "A"
def methB(self):

Hello,
Could someone explain to me why the Standard conveners chose to typedef
std::string rather than derive it from std::basic_string<char, ...>?
The result of course is that it is effectively impossible to forward declare
std::string. (Yes I am aware that some libraries have a string_fwd.h header,
but this is not portable.)
That said, is there any real reason why I can't derive an otherwise empty

Hi,
I have a problem with compiling the following construction involving
cross-calls of class template methods, with additional inheritance.
I want to have three class templates:

As all we know, in order to remove cyclic includes in C++ we seperate
the declarations and definitions of classs and it's member in two files
Header (*.h) and source files (*.cpp). This is not a problem for C# as
there is no concept of include.
I faced problems for seperating declarations and definitions for class
when it contains properties. This can also be done in context
of struct/structures. Here is how we can.

Hello,
I made a base class for all the pages in my project, so that instead
of "public class CSomePage : System.Web.UI.Page" i got "public class
CSomePage : CPage
Since some parameters are common to all pages, i did put some server
hidden fields controls in the base class.

This may be more of a Visual Studio question but those groups seem to
be full of unrelated stuff so hopefully this might be the right place.
I have a class (no associated aspx file) which handles all the common
startup code for the pages on our website. It is derived from
System.Web.UI.Page and every page in 2 separate projects (web
applications) derives from it. It contains several declarations of
server controls such a navigation bar...

If find the following excerpt from the Standard a bit confusing:
<quote>
3.3.6 - Class scope
-1- The following rules describe the scope of names declared in classes.
1) The potential scope of a name declared in a class consists not only of
the declarative region following the name's declarator, but also of all
function bodies, default arguments, and constructor ctor-initializers in
that class (including such things in nested classes).

hello,
i've run into an error when qualifying a copy ctor 'explicit'. the
strange thing is that i get a compiler error only if the class is a
template and declare the variable as X<Zx = y. X<Zx(y) is fine.
Tested with gcc 2.95, 3.3, 4.1, all gave the same error:
t.cpp: In function 'int main()':
t.cpp:44: error: no matching function for call to
'D<int>::D(D<int>&)'

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...

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,...
