Hello,
I was wondering when multi-file assemblies may be useful.
With multi-file assemblies you may place inside the same assembly
netmodules coded in different languages and as a consequence code from
a module may obviously utilize private and internal classes defined in
other module (maybe even coded in different languages). Apart this I
personally see no other reasons to using multi-file assemblies.

into the interface. While the file is loading, I want to display a
VB.NET form with the list of messages generated during the process. I

back-end. I'm pretty sure I need to use multi-threading for this but
I am having a lot of...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

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...

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,...
