Here is an odd issue. I am trying to shed some light on why this is causing
a problem.
I have an ArrayList. I am binding it to a ListBox control with has its Sort
property set to True. If the ArrayList only has one element in it everything
works ok. But as soon as I have more than one element, I get the following
exception when the control loads up: "Cannot modify the Items collection
when the DataSource property is set.".

Hi There,
I am trying to return the value of a listbox control that is included as a
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'm confused.
I have a listbox. The DataSource is a DataTable based on a SQL Select
Statement that includes a where clause. For example, "Select ID, FirstName,
LastName From Employees where DepartmentID = 5"
I have three controls on the same form that are bound to this datatable. So
far so good. I click through the list in the listbox, and the controls
reflect the current selected item in the listbox. (Nice!)

I haven't found exactly what I've been trying to do.
All I am trying to do for now is just display usernames from Active
Directory into a ListBox control on a page. I have found some code
however that will just capture a Full Name from Text Box and display
information from the Active Directory into a DataTable. I will display
that code below.

I have a GridView control in page called which is inheriting
from a MasterPage. The normal code to export to GridView does not work and
gives me an error - "Control of type GridView must be placed inside form tag
with runat = server". I understand that this is because my Masterpage has the
formtag and not the eventslisting page, but cannot figure a workaround.
I have tried overriding VerifyRenderingInServerForm and everything else I
can...

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,...
