Hello NG,
Regarding access-declarations and member using-declarations as used to
change the access level of an inherited base member...
Two things need to be considered when determining an inherited base member's
access level in the derived class: its access level in the base class and
the type of inheritance (public, protected, or private). After this
determination is made, the following possibilities exist for manually
changing the...

Hi all,
I have a site with the following architecture:
Common.Web.dll - Contains a CommonPageBase class which inherits
System.Web.UI.Page
myadd.dll - Contains PageBase which inherits CommonPageBase
- Contains myPage which inherits PageBase
Each of these classes overrides OnInit and ties an event handler

Good afternoon everyone. I'm running into a problem deserializing a stream

In my code, person is the base class and student extends it. When I

Question: Why can't you access a private inherited field from a base
class in a derived class? I have a *theory* of how this works, of
which, I'm not completely sure of but makes logical sense to me. So,
I'm here for an answer (more of a confirmation), hopefully.
First let me say that I know people keep saying; it doesn't work
because the member "is a private". I believe there's more to it than
just simply that...
Theory: You inherit,...

I have a class that may or may not be inherited.
Its constructor calls a function that should be
called only if the class is not inherited. Is
there a way to tell, other than simply passing
a bool argument?
Thanks for your suggestions.
Mike.

This question concerns something I'm trying to do with the CF but it's really
a generic C# question.
With the Compact Framework, one can't add a radio button with a long label
because the labels don't wrap. So I've decided to create my own custom radio
button. With my version there will be a basic radio button with no text and
its size reduced to 12 x 12. Then beside this I will place a LinkLabel,
which will wrap, to give the...

I have a windows Form that inherits from Base_form. In Base_form I added a
panel that covers the whole Form (panel1.Dock = Fill). The problem is that
all the controls in the Form that inherit from Base_form are "under" this
panel, which means they're not visible..
Is it possible to make these controls visible again without having to make
major changes in the Form?
Thanks.

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,...
