Hi,
Does anybody know where this term comes from?
"First-class object" means "something passable as an argument in a
function call", but I fail to see the connection with "object class"
or with "first-class airplane ticket". I just find the name a bit
strange. Also, if there are first-class objects, what would the
second-class objects or economy/tourist class objects be? :)

Hi, I have a problem with unittest.TestCase that I could really use
some help with.
I have a class File in module File. The important thing about File for
this discussion is that it's simple - no pool of objects are involved,
and subsequent invocations of File.File('filename') should return
distinct objects (and indeed, they do on the command line). Also,
__repr__ prints out the value of id(self) for File, so I can tell
what's going on...

Any ideas why and how to fix would be appreciated.

1. What is the best way to make a single instance of my top level class
(DLL) internally available to all other members of the assembly? The top
level object is where all other access is made in to the program. Where and
how do I declare and initialise this object?
For instance, it would have property implementation like this:
//*******************************************
public MyClass1 Class1

Hi,
I have been using the following line of code to create an object called
"Serious" if it doesn't already exist.
if (Serious == null) {var Serious = {};}
This works in the scripts I use it but but www.jslint.com is not happy
with me.

I've marked the line in this subroutine where I've been getting this error.
It may be something stupid but I've been staring at this error trying to fix
it for over an hour. I'm pretty sure the table and field names and controls
are all named correctly, and the control referred to in the errant code is
open, and it has data in it.
Private Sub cmdAddIngredientToRecipe_Click()
' Get RecipeID for future action query
Dim recipeID As Long

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 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...
