that is bound to
myDataTable's myDataView. The column "Name" is the primary key.
I want to delete the rows selected by the user:

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
each column in the datagridview? Or is there a way to retrieve the rows from
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 wondering how you guys highlight cells or rows (by changing the
text or background colour) in a DataGridView. Right now, I apply styles
to certain rows or cells in the CellFormatting even handler, but the
way it works is by looping through all of the rows and then deciding if
that rows needs special formatting.
The problem is that I don't think this method will scale well. I have a
dataset with 5,000 rows (and others are larger, this...

I have a DataGridView that has potentially several hundred rows
(possibly a thousand or two).
I'd like for each row to have the proper height to accomadate the text
in the row. I tried setting the AutoSizeRowMode to AllCells. This
worked great on small datasets, but the program hung for a long time on
larger datasets.
I changed it to DisplayedCells, but this has some quirks: All of the
initally displayed rows are the correct height (for...

I'm having a really strange issue with the DataGridView control in a VS2008 / .NET 3.5 winforms project. I have a simple form with a grid. In the form constructor I call a function to bind the grind to a DataTable, and then loop through the rows setting the background colour of the last cell to LightGrey and the cell itself to read-only if the column value is true. After the form finishes loading the code didn't work i.e. the cells are not set...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
