I've got a very large C# forms app and now that its being used in
bigger environments we're getting a steady stream of "why does it do
this?" problems. The most nagging of which right now is that when a
MessageBox.Show() is displayed, if the user hits enter or esc, those
keys get passed back to the form. From searching online, this is
apparently by design(for whom, I don't know, why its not optional, I
_really_ don't know). This...

I am writing a curses application, but the getch() does not seem to
give me all I want. Of course, if I press "d", it returns an ord("d")
and so on. But I want to be able to detect whether alt, shift or ctrl
has been pressed also. Shift is normally covered by returning an
uppercase character instead and ctrl seems to return control codes (as
is normal, I guess), but alt I can't detect with getch, it seems.
Preferably, I would like one...

Hello All,
I'm really looking for a help in reading/writing the keyboard buffer in AIX (IBM Unix). In DOS, there is some memory addres (I remember it as 0x417) from where the keyboard buffer starts. But I need the same in AIX.
My requirement is this. In AIX, we need to change the password every 60 days or so. And while changing, it wont accept the previous 4 passwords we used. But when you change to a new one, its difficult to remember the...

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...
