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:

Ok - I have a ListBox control and I'm ready to write my own DrawItem event handler.
What I want to draw as the item is another control. I have created a user control that I
would like to list in this listbox but I can't for the life of me figure out how to draw the
control inside ListBox...
I get as far as:
private void lbImageList_DrawItem(object sender,
System.Windows.Forms.DrawItemEventArgs e)

I am populating a multiselect Listbox from a dataset, with the content of
the listbox filled by one table, and the selections determined from another
table. So far, I have been keeping the dataset a denormalized mirror of the
database, but I'm not having much luck getting the selection logic down (I
haven't found a 'hook' where I can access the listbox object as an object to
set the listitem's selected property before it gets rendered)..

user control, I can return the name of the control but I can't access the
integer value of the selected item, what do I need to do in order to return
the "option value" of the control?

I have looked all over the net for an example on how to use this function
but got no joy, lots of jargon explaining the function but no examples.
In VB.Net the hwnd has gone there was one in vb6 - I tried using Handle but
nothing happens
Can anyone shed some light on how to use this function or give an example?
Many Thanks

Hi,
There is a ROW property on the Web Listbox control within VB.Net. The
description states it is "The number of visible rows to display".
I have tried setting this property in many different ways. It does not
appear to do much of anything. I was trying to use it to control the
actual size in rows of the list box on the Web page. But the size of the
Web listbox seems to be fixed and controlled by the size of the control set
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

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,...
