Hi everybody,
I am creating an intrusive list ('next' and 'prev' pointers are stored
within an object that is in a list). One method of doing that is to inherit
all objects from some class that contains these pointers. However, it is
unacceptable for my problem, because it limits the number of lists the
object can be in to 1. I must have some objects in more than 1 list. Instead
of inheriting, I use aggregation:
class Node { //...

Hi People,
I am trying to create a Help Screen in a program. I want to swap out the

Hi!
I've been thinking about passing parameteras using references instead
of pointers in order to emphasize that the parameter must be an
object.
Exemple:

Hi,
I am using intrusive pointers for my code but i am not much aquianted
with them. I am using an example to illustrate my problem as i can't
share the code.
I have two clases ( say A and B)
B is derived from A( B: public A)
now i want to pass the this* pointer of the derived class(B) to a

If an Object is holding a valid reference to an Object, should I set it to
Nothing before I set it to a another Object of the same type?
ex:
Dim objNode
Set objNode=Node1 ' Say node1 is some expression
' Do some processing and then. Should I set it to Nothing?
Set objNode=Node2 ' Say node1 is some expression

I might be overworked so please excuse this stupid question...
Say I do the following:
DataTable table = new DataTable();
myDataAdaptor.Fill(table);
dataGrid1.DataSource = table;

Hi,
My question is related to setting freed pointers to NULL.
After freeing a pointer:
1) Should the freeing routine also be responsible for setting the
pointer to null?
2) Or, should the client/user code be responsible for doing it?
On what basis should a decision be made favouring either case ?

It's my understanding that intrusive pointers are frowned upon. For example
this is from the boost::intrusive_ptr documentation: "As a general rule, if
it isn't obvious whether intrusive_ptr better fits your needs than
shared_ptr, try a shared_ptr-based design first."
This tells me that intrusive pointers are faster and leaner than any of the
other alternative other than raw pointers.

I've been trying to write a function capable of checking if a pointer
value is set to NULL, and if it isn't, of deallocating and setting
it's value to NULL regardless of the pointer's type. I thought "void
** " should do the trick, but I kept getting the following warning
message from gcc:
warning: passing argument 1 of 'free_var' from incompatible pointer
type
which obviously could be solved by doing an explicit cast to (void **)

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
