Hello !
When a ref. counted smart pointer (template) class is available (like
boost::shared_ptr), is there any (semantic) reason to still use
std::auto_ptr rather than this smart pointer ? Or should one use shared_ptr
for every cases ?
Thanks in advance for your remarks !

Hi, all!
I didn't find yet solution for this problem! Somebody knows where is a
catch?
Looks like "operator =" or copy constructor not implemented in one of
internal templates....
Thanks in advance
class CMyBase;

It seems that the use of auto_ptr<> is discouraged in many places in
favor of boost::shared_ptr<> (or tr1::shared_ptr<>). But consider a
PIMPL idiom, where there is a strict 1-1 relationship between interface
objects and implementation object, and the implementation object lasts
for the lifetime of the interface object.
i.e.
// header file
class WidgetImpl;
class Widget {

Hi All,
Everyone tells me that auto_ptr is a good idea, but auto_ptr and COM don't
play nice. Can someone please explain why auto_ptr and COM don't like each
other and what a reasonable/typical solution is? My guess is that auto_ptr
will call the destructor on the COM object which is bad because it should
call Release(). I'd like to avoid manually calling Release(), because my
function has a bunch of places from which it can return,...

I can't believe I am unable to get this simple thing right.
I have an auto_ptr class to a structure type. I have it as a member
variable in my class.
struct Y
{
SomeType& m_st;
Y(SomeType& st) : m_st(st) { }
};

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,...
