I'd like to be able to get the name of an object instance from within
a call to a method of that same object. Is this at all possible?
The example below works by passing in the name of the object instance
(in this case 'myDog'). Of course it would be better if I could
somehow know from within write() that the name of the object instance
was 'myDog' without having to pass it as a parameter.

Memory usage wise is it a good idea to specify methods in utility/helper

Hello:
We have an application that generates a static database layer based on
stored procedures defined in SQL Server for consumption by client
applications. These classes contain a slew of static methods. In many
cases you only need to use 4 or 5 of these to retrieve/update data from
the db. It seems like a collasal waste to have all of these excess
static methods hanging around. When are these static methods loaded
into memory? ...

Sometimes a method in a class requires the use of class instance
variables/fields that will not be used outside of the method itself.
Currently this means you must create a instance field in the class such that
from a maintenance stand point it is disconnected from the method, and also
affords the opportunity for other methods to mess with the variable when they
never should.
For example:
public class MyClass

I have a "CurrentUser" object in session that I want to access from
each page of a vb.net website. I can successfully access everything if
I include the following at the start of each pageload:

If objCurrentUser Is Nothing Then objCurrentUser = New

Hi everyone!
I am debugging a big piece of code on the search for memory leaks,
using g++ under suse 9.3.
Since I'm trying to eliminate ALL memory leaks, I now stumbled upon a
class foo that is not ever instantiated (thus no constructor or
destructor ever called), but instead, all of its member variables are
defined as static in the according .cpp file, and it's methods are
invoked by calling foo::bar(...) to invoke method "bar(...)".

I have a global.asax file with Application_Start defined and create some
static data there and in another module used in the asp.net application and
I realize that static data is shared amongst child apps of an IIS

cycle and for multiple page loads for the same or different page under a

pointers to static buffers that may be overwritten by other function
calls".So how is the"static buffers"...

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
