Hi,
If I want to call functions that don't return int without declaring
them, will there be any harm?
I only want to assign the function(return value) to the type that it
returns, so I don't see how the return value comes to play here.

I am trying to set up a class to handle my database accesses.
I can't seem to figure out how to get the return value from my dataReader
from these routines (most of which I got elsewhere). They do work pretty
well, except for the change I made to get the return value.
For example, I have the following:

Hello,
I have a BaseClass and many Classes which all inherit (directly) from the BaseClass.
One of the functions in the BaseClass is to (de)serialize the (inherited) Class to/from disk.
1. The Deserialization goes like:

Hello experts,
Is the following code snippet legal? If it is, how can exit() do the
keyword return a favor and give a return value to the main function?
Can a function call (or only this exit(n)) statement provide both
function call and return features of the C programming language?
/* headers omitted */
int main (void)

I've been doing COM a long time, but I've just come across a behavior
with late binding that surprises me. VB and VBS are not my normal
milieux, so I'm hoping someone can point me to a document that
describes this.
Here's the setup. We have a COM server, written in Python. For
completeness, here is the script:

How do I get this to work? It always returns False, even though I can see
"This is True!" in the debug window. Do I have to invoke functions

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

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,...

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...
