Hello,
I am populating a datagridview from a datatable and filtering the number of
rows with a dataview object. Is there a way to retrieve the rows displayed
by the datagridview into a separate datatable without having to loop through

the original datatable filtered by the dataview into a separate table? I
only want to copy the rows from the main table that...

I am trying to find the event (if there is one) which occurs when a row
is added to the DataGridView.
The closest I can find is the RowsAdded event which says in documentation:
Occurs after a new row is added to the System.Windows.Forms.DataGridView.
OK then so I debug my code. I am adding 11 rows with a datasource and I
get 4 occurences of the RowsAdded:

I have DataGridView in virtual mode containing 3500 rows.
In code below, assigning to RowCount value to 3500 takes 8 seconds.
CPU usage goes high at this time.
Stepping by F11 into user code shows few celltemplate property getters and
combobox/datecombo constructor calls without database access which does not
take a lot of time.
Debug output (below) shows lot of messages Stepping over non-user code.

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:

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,...
