I am trying to implement inheritance but I am having a difficult time with some concepts.
What I am trying to do is have a Child object inherit from the Parent, and when you set a property value at the Parent level, I want all of the children to see this change. Likewise, when I set a Parent's property value in the child object, both the parent and all of the children see the change.
Maybe what I am trying to do is not "inheritance" after...

Hi,
I am able to obtain a MenuItem object's Name property @
design-time, but am not able to get the same @ run-
time...why?
And since MenuItem doesn't inherit from Control class,
it's not even supposed to be available @ design-time
right?

I've written a composite custom control which I would like to have update its design-time display when one of several properties
changes at design time. These custom properties are not simply the exposed properties of the constituent controls (e.g., they
control how many constitutent controls are displayed).
I am at a loss as to how to go about doing this. I have a custom designer for the control, but I don't see any functionality in the...

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...

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,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

Hello
I'm a network technician in training and I need your help.
