language related than ADO.NET.
How can I write the constructor for specialization of DataRow which will
take a datarow as parameter. Something like:

I have a function that populates a class with values from a database. I'd
like to pass into the function either a SqlDataReader or a DataRow,
depending on which mechanism I'm using to retrieve data from the database.
However, the two classes don't appear to have any common interfaces that
would allow me to enumerate the fields. Yet, when you databind you can pass
either of these classes (as well as many others) and .NET somehow knows how...

I use the code below to search through a DataSet:

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

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,...
