I thought I could create a "ListViewItem" and then bind that item to a
combox box, but perhaps that is was with an ASP.Net control. When I create
a listViewItem and bind it to a combo box, it does bind, but what show up
is something like ListViewItem{MyField}.
So if I have a hastable, what mechanism would I use to create a bindable
object such that I can define the "ValueMember" and "DisplayMember"?
Thanks in advance for your...

Hi,
I have a function that loads Rows from a field in a DataTable into an
ArrayList.
See below:
It also adds a Row (eg "All Areas").
I wanted this new row to be the first record so I added a preceeding space
(eg " All Areas") and sorted the ArrayList.
I have just found that there are some valid records that have one or more

I'd like to copy a object1 into object2 so object2 can be manipulated.
Object1 is coming form the middle layer into the UI layer. I'd like
to rename a field in Object2 from "somethingID" to just "ID" and do
this several times for a few middle layer objects. This will allow me
to create generic<> lists and reference the field ID against many
object2s that are similar to object1. The middle layer objects have ID
fields with different...

Here is an example of a SortedList that works as a datasource to the ComboBox
and a generic SortedList<that does not works as a datasource to the
ComboBox.
Why? If I use List and generic List<>, both works.
private void Form1_Load(object sender, EventArgs e)
{
System.Collections.SortedList QA1 = new
System.Collections.SortedList();

Hi Group.
First of all I'm sorry for asking (maybe) such easy questions. But I'm
quite stuck now and couldn't come up with a solution by using my C#
book or googling. So it would be nice if someone could help me out.
Now first of all I want to describe the setting in a simpler (I'm using
Visual Studio 2005):
Form: One comboBox (dropdown list) and 2 buttons.
Classes: Class1 with a function do() which plainly returns a string.

I'm using a ComboBox to display objects of a class I've defined, say CQQ.
Works great except somehow I occasionally set an Item to a String object
instead of an object of type CQQ.
It looks like Text replaces an item or something like that.
This results in a runtime error at which time I learn that the item that
should be CQQ is a String.

Can you see why this does not sort the list?
It displays OK but is not sorted

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,...
