Im puzzled by a data validation behavior I don't understand, related to
enums.
Stripped down scenario:
enum Type {One=1, Two=2, Three=3}
Type var1 = (Type)40;
These two lines of code don't cause a compile error.
In VB, trying to assign a value to a variable of an enum type does cause a

I've got an abstract class (say foo) and I'd like to define an Enum (say
bar) within that class so that I can then refer to foo.bar.<one of the enum
labels> from within other parts of the program. The enum is *public* in
other words.
What I find is that while the compiler allows the enum declaration within
the abstract class, it turns out that the enum type isn't visible from
outside the class. It is visible from within descendant...

If a class inherits from another class, say Form inherits from control, then
I can assign the Form to a variable of type Control without needing an
explicit conversion, eg
Form1 f = new Form1();
Control c = f;
An enum value inherits from int but it doesn't get implicitly converted:
HorizontalAlignment h = HorizontalAlignment.Center;

Hello,
I have have module where I have created a public enumtype that I want to
reuse in different classes .
As soon as I create a public property with this type . Vb warns me that the
'Friend' type can not be used as a public type .
Option Strict is on , so it's possible that this problem only occurs in this
case .

Which of the following is better? Defining an enum type inside a class
as a nested type, or in the the namespace?
An example of nested type enumerated type would be:
public Class Product
Public Enum Status
psNormal
psCharged
End Enum

Hi,
I have some enum (enumeration ) defined in some namespace, not inside
class. How to use the enum constant's in some other namespace without
using the whole namespace.
To say in little detail, the enum is declared as,
namespace test{
enum MyEnum{
VALUE1,VALUE2
};

So I was needing some extra power from my enums and implemented the
typesafe enum pattern.
And it got me to thinking... why should I EVER use standard enums?
There's now a nice little code snippet that I wrote today that gives me
an instant implementation of the pattern. I could easily just always
use such an implementation instead of a standard enum, so I wanted to
know what you experts all thought.
Is there a case for standard enums?

Hi everyone,
We have a c++ server application that we are writing a GUI client
application for. To save our time and to avoid duplicating all the code and
functionality that already exists in c++ classes I am building a managed c++
assembly around these classes so that a c# program can use them.
The problem is that alot of these c++ classes use enums, I would like to
make these visible to the c# application but I cannot find a way to...

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,...
