I'm playing around, albeit quite seriously, with Visual C# 2005 Express
Edition. I added a DataGridViewTextBoxColumn to a DataGridView. I want to
only allow this column to contain left parentheses. I also have one that
should only contain right parens, in case you're wondering. I couldn't find
a property where I could designate an input mask as such, so I decided to
try to handle the KeyDown event and override anything but the desired...

::: Question:
Does anyone know of a simple Control / UserControl implementation that hosts
a UITypeEditor? Or the correct way to call PropertyDescriptor.GetEditor()
and get a non-null result for usage in a Form?
::: Background:
Basically, I have a highly-dynamic (runtime) bespoke object model, and I
want to drop some (runtime-only) properties onto the form. As it happens,
the objects implement all the right interfaces for Binding to...

I try to implement a AutoComplete function to the datagridviewtextboxcolumn
to a Datagridview control with several others datagridviewtextboxcolumns.
This function is meant to apply to the column, CustomerID, in the
datagridview control. However the AutoComplete function occurs on EVERY
datagridviewtextbox column with the same datatype - string. For example the
function should be at the CustomerID column which has the column index =1,...

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,...

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...
