I have a question about assigning __call__ to an instance to make that
instance callable. I know there has been quite a bit of discussion
about this, and I've read all I can find, but I'm still confused.
I'd like to have a factory class that takes a string argument and returns
the appropriate factory method based on that string. I'd like the
instances to be callable. Like this:
fact = Factory('SomeThing')
aSomeThing = fact(some...

Hello.
I have a javascript object with one attribute (name) and one method
(showName). Each object instance appends a DIV to the document's body. I
want that when the user clicks over the DIVS the alert shows the name of
the instance which has created the DIV.tancia que ha creado ese DIV:

In our new .NET web applications, we try to limit the use of SqlConnection
to just one instance per page, even if there are multiple accesses to
various queries. The thinking behind is that this reduces the need to
getting and returning connections to the pool repeatedly if a page has
multiple calls to the DB, and each one manages its own connection. However,
this does requires more deliberate coding, like calling the...

Hi,
I am running into something I haven't ever encountered before. I have a
static instance of a class declared in a cpp file, which seems to be
optimized (or for some other reason) out of existence. It is something like
the following:
foobar.hpp
class foobar

Hi,
How do I give create database privielege to a specific user/group at a
particular db2 instance ?
I read about various authorities like SYSCTRL etc. but I am interested
in giving only Create database privilege.
I also came across GRANT <system privilege statement and it seems I
can execute following statement to achieve what I want,
GRANT CREATEDBA to <authorization-name>

I am VERY new to C++ (1st semester) put not so new to coding and
programming (SQL, VB, etc). We are learning about classes.
I have a program that needs to call many instances (i think this is the
right term) of a class.
What I have been taught so far is to write to a class we would do
something like this in the main.cpp:
a1.setmanSalary(something);

If I have a procedure that will be run simultaneously by several people
which requires the use of a temporary table is there a way for the table
to be accessible only in the instance in which the procedure is being
run so that multiple tables can have the same name but not have
collisions? I would normally think to name the table with a random
string but apparently SQL rules do not allow dynamically generated table
names. The other thing...

I suspect the answer might be in one of the words of my subject, but here
goes anyway.
I'm working on a system that will execute a very long (300+) chain of task
objects. Here is some quick pseudo code to illustrate:
public class VideoAcquisition
{
public Image GetFrame(){};

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
