Hello,
I'm using a windows form in which there is a standard ListBox control. I
want to add/remove objects from the ArrayList associated to the ListBox, and
I want the ListBox immediately shows graphically the change: e.g. if I
remove an element from the ArrayList object, then that element should not be
no more displayed in the list box.
Actually i'm using this code below:

Hi
I have some code to create an ownerdrawn listbox (derived), and when I add
an item to it, the bold text of the first item (the title, 'Collections and
Maturities') mysteriously seems to get bunched up at the right, i.e. squashed
up! any idea why?
The main bit of the code is as such
// (in progressReporter.cs)

I am having a terrible time getting anything useful out of a listbox
on my web form.
I am populating it with the results from Postcode lookup software, and
it is showing the results fine. What I want to do is to allow the

have the code behind populate the form's Address1, Address2 etc.

I've got a listbox that holds a list of groups. Users can
select a group, hit the remove button and the group
should be removed from the listbox. The only problem is
that no matter which group you select, the first one in
the listbox is always removed.(The listitem with an index
of 0. Box is set to single selection mode) I've looked at
multiple examples and they all do it this way. What's
wrong? (variables are also being set to the values...

For some reason I cannot get the OnSelectedIndexChanged event to fire for a
listbox I have on a page. I'm able to populate the listbox with data from a
stored procedure, but cannot trigger the event. I do have EnableViewState =
True for the listbox. I'm imagining (wanting) to populate the listbox named:
lstNames by using the DataValueField from lstDepartments.
It's quite apparent though that the event is not triggering as I can misname...

I'm still struggling to find a way of reordering the items within the
same single listbox with drag and drop. I think I've got the drag
working but it's the drop code I can't figure out. What I have
currently is (with the listbox set to AllowDrop):
Sub MyListBox_MouseDown(args etc...)
DoDragDrop(MyListBox.SelectedItem, DragDropEffects.Move)
End Sub
Sub MyListBox_DragEnter(args etc...)

Is the following a correct representation of the relationship of the selected
index to selected item:
INDEX ITEM
0 "item 1"
1 "item 2"
2 "item 3"
and so on.
I keep getting the same string for selected index 0 and 1; i.e. both are
"item 1".
I'm new to C# and not exactly an accomplished programmer. Any suggestions?

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

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
