Hi,
Given: I have a class with protected or private data members, some of
them without accessor methods. It's someone else's class, so I can't
change it. (eg, I can't add accessor methods to the parent class, and I
can't make some "helper" class a friend of the parent class to help in
accessing the data.)
Problem: I want to derive a class that has a copy constructor that
properly copies those data members.

The Control class has the Parent property that is readonly.
When the control is added to a controls collection of another control the
Parent property refers to that control.
"Who" set the Parent property? How to implement this "mechanism"?
public abstract class MyControl
{
private MyControl parent;
public MyControl Parent{get{return this.parent;}}

Hi,
I have a page with a very data intensive grid which needs to be
automatically refreshed constantly if a change is detected. In order to
not refresh the complete page so often, I created an iframe on my page
whose html has the refresh meta as follows :
<meta http-equiv="refresh" content="10">
The iframe is effectivelyh refreshed every 10 seconds without having the

Ok, this is incredibly annoying. Below I have an ImageButton and it's
ImageButton_Click sub. See the 6 response.writes? The output for them
is displayed below in asterisks. Question: What part of the
TemplateColumn below does sender.parent.parent.Cells(9) reference???
IOW, what tag does it reference? The templatecolumn is the 9th field in
the datagrid yet no matter what I do, whatever

What is the feeling on using "parent" in a class definition that
class methods can refer to, vs. some other organization ?
Should all relevant objects/vars just be passed into the method as needed?
It seems like including "parent" in the class def is just like a
class variable, which most do not recommend.
An example:
class LXSerial:
def __init__(self, parent, debug=False):

In my user control, I would like to find a Label control in the parent
page (the page that uses my user control). I need to update that
Label.Text when something happens in the user control.
I don't want to go through the hassle of creating events in the user
control, and then let the parent handle the event.
What is the easiest way to find a control in the parent page? Right
now, I am simply manually traversing it from the user...

This is C code. I am trying to fill each node's Parent field with its parent because I am drawing nodes to the screen. However, I have not been able to get this working. Reading the output from the code and tracing it, it seems that the code does not continue recursing down into the tree to insert. Can someone please point me to what is wrong and help me understand why it is wrong? Thank you.

I want to create a set of Activity Diagram controls for process control.
I need to create a base Diagram control that acts as a container for 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
