Is there a way to automatically close the data reader connection? I'm using
the MS Data Access Application block to substantially {entirely} separate
the data access layer (DAL) from the business layer (BL) and this is great
with DataSets since they can be closed off in the DAL, but it doesn't seem
possible with the DataReader since it would need to be .close() in the BL
once I'm done with it.
I've read on the web that there is a bit of...

Hi,
I have a situation where I have two datareaders, and I want to make sure any
given field from Datareader A exists in Datareader B before I can do
anything with that column.
I tried the code below but I get an exception thrown because the column
doesn't exist in Datareader B.
I'm not opposed to using another method but the same thing happened when
using a Dataset. How do I do this??

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
