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've got a loop from within which I make a call to the API function
GetAsyncKeystate to see if the Escape key was pressed. If it is, then the
exit condition of the loop is met and the program goes on to display a
simple messagebox. Unfortunately, the program seems to think the Escape key
was meant for this messagebox, even though it appeared *after* the Escape
key was pressed(!) and instantly closes the messagebox before you can even
see...

Hallo everybody
Does anyone knows how to access Keyboard buffer?
At the moment I'm catching KeyDown event of the form, and waiting for
carrige return or return key,
but sometimes the Keyboard scanner doesn't send those keys, so I would like
to wait so long until keyboard buffer is empty.
Any helb will be appriciated

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...

I've been trying to use _kbhit() but it didn't do what I thought it
would from books, "Detects whether a keypress is available for reading."
Herbert Schildt says,
"If the user has pressed a key, this function returns
true(non-0), but does not read the character.
If no keystroke is pending, kbhit() returns false (0)."
Here is the test code,

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...
