I have an array/hash that stores path information for my app. As in,
what directory this is in, what directory that's in, what the name of
the site is, what the products are called, etc. It's called $glb.
So, every function so far looks like this:
function something() {
global $glb;
}

Hi and Season's Greetings to all.
I have a question regarding the use of a qualifier word "Global". I cannot
find any reference to this in Access help, nor in books or on the Internet.
"Global" seems to be recognised by Access in at least three cases:-
1) "Global Const". Recently someone in this group helped me resolve a
problem, and it involved the use of a Global Const. By Googling "Global
Const", I got plenty of hits -- but they...

Hello all,
I might be missing something here, but am trying to understand the difference between using application-level variables--i.e. Application("MyVar")--and global variables--i.e. public myVar as string, etc. It seems to me that the scope and duration are the same, as they both are there while the application is running, and both go away when it quits. I presume that one difference is that the application state can be "flushed," such...

If I have a class that hold, for instance, user settings that should be
accessible to the entire program logic, what is a good paradigm to use?
In C++, I would have made it a global object, protected if necessary
for thread safety. In C#, of course, there are no global objects.
The Program object is static, so cannot contain object instances.
While I could store it in my main form pass it around, that seems
cumbersome. I could do a...

I have this nasty problem with Shared methods and what I think of as "global
storage" - i.e. storage declared outside of any subroutines or functions.
In the simple example below this "global" storage is ButtonHasBeenClicked.
In this simple example code in Form1 calls a routine in Module1 which then
calls code back in Form1 (subroutine WhatEver). WhatEver needs to access
ButtonHasBeenClicked but the reference to ButtonHasBeenClicked...

Hi,
I am having trouble understanding the use of 'global' variables I want to use a global variable with the same name as a parameter of a function. But I don't know how to use them at the same time. Here is a snippet of example code:
def foo (a):
global p
global a
p = a + 3 #here "a" will be reference to the global one
a = 1

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,...

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...
