Dear C++ gurus,
I'm having some problems inserting some template classes into containers.
I'm looking for ideas, suggestions,... on how to achieve this but first let
me explain my problem. Everything starts with a simple template class like
the one below. In this example class A has two template parameters but that
number can be different.
template < typename T, typename U >
class A

Is there a way of implementing something like the Template Method design
pattern, but only dealing with static methods ?
First, I realized that I can't have abstract static methods in the base
class to be implemented in the derived classes.
Second, I have tried to hide those methods of the base class, with the 'new'
modifier, bub it doesn´t work.
I would appreciate your help ver much.
Thank you
Juan M. Cervera

I am trying to create a template in dot net. All the articles I have
read on the net are rather confusing. I need a simple solution to
create a header and a footer on each page. Can someone point me into
the right direction.
I started off creating a file template.cs:
using System;
using System.Web;
using System.Web.UI;

Hi Everyone,
I have a dynamic checkbox in a datagrid that uses the ITemplate interface
and has the checkchanged event wired up. When the checkbox is checked, the
event
event handler that handles the event gets called, however when it is
unchecked, it does not fire. Is this by design, or is something else that
is going on? Thanks!!.

Hello folks,

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
