Hi,
I've worked out how to find the 2 COM Ports on my motherboard ok, using
System.Manageme nt namespace and looking for Win32_SerialPor t.
Problem now, is I have 3 COM Ports on USB connections, but can't seem to
find a way to query for them.
Any suggestions?

I do it by iterating through each possible COM port attempting to open each
one in turn. Something like this:
FOR nPort = 1 to MaxPorts
Attempt to open COM<nPort>
IF (it succeeded)
Add nPort to list of available ports
Close COM<nPort>
ENDIF
ENDFOR

Hi,
I do need to implement something similar to C++'s std::bitset in C; for
this, I use an array of int's to get together any desired number of
bits, possibly larger than 32/64 or anything like this.
So of course it does not matter how many bits a single int has, but I do
need a reliable way to find it out.

Hello, everyone. I recently took a class on Data Structures in C++
(using D.S. Malik's C++ Programming: Program Design Including Data

for my liking. I passed the class with flying colors, but I think it

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:

For most users, this new feature is actually very convenient. If you want to control the update process,...
