Hi people,
I need to write a C# program which communicates with a thermal printer.
After a search for the web I found that a way to comunicate with the ports
is calling the kernel32.dll, which has some external methods (CreateFile,
WriteFile, ReadFile, Get/Set CommSettings, Get / Set CommTimeOuts) to
communicate with the port.
My first problems with this dll is that I couldn't find the right

Hello,
Five years of development has us using a very large database (a
couple hundred screens) in one location, which is very managable. Now
our company will be expanding to several distant states and wants a
live database throughout.
What are my options? One suggestion was that we make a
web-based application for ease of updates and availability to remote
sites. That would, of course, involve a complete rewrite of the front

I have a USB printer connected to my PC. My winform app prints out some
text using the typical print methods that are normally used. I will
then turn off the printer or disconnect the USB cable. My application
still prints fine and reports no error. Of course, then windows pops up
a balloon from the system tray alerting me that the printing failed.
The print job just sits in the printer's print queue, until I reconnect
the printer and...

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
