Hi,
I'm having a little problem catching keystrokes under Windows. I did a
little research and found that with mscvrt.getch() one can cath a single
key that is pressed. However this doesn't work when the program is run
on the backround and not as the primary task. What I would like to have
is a same sort of function that would also work when the program is being
run on the background. I'm trying to implement a program that would listen...

Hello,
I read a file from several classes and want to catch an EOF when it
appears.
Having caught the EOF I want to allow the final part of the program to
continue rather than just exiting.
At present I use methods which read from the file; test the read was
successful and return a 1 if not. This is then checked by the calling
method, which also returns a 1 if the other method returned 1 (thus

On most architectures integer division by 0 results in throwing an
exception (does anyone know of one that behaves differently?). I need a
way to catch FP division by 0. Is there a standard way to do so?

ok the function is supposed to accept only non-negative integers... but it still accepts letters input through the function. Such as '23e' still passes through. I tried to use isalpha in the or statement to cause an error, but it causes an error for everything input. How do I make an error occur when anything other than numbers are put in?

Hi All,
I have been crunching my brains on this one all day. I use this library that
creates output I want, but it can only write it to a file or the stdout. The
problem is that I don't want to use the filesystem (permissions, latency
through NFS, etc, etc), but a memory buffer. I've been looking for a way to
redirect stdout to a buffer that I manage myself. Obviously I considered
setbuf (from stdio.h), but then I'ld still have to...

How can I prevent the big close button in the top of the window from
closing the window?
I want to have and "are you sure?" confirmation so the user must press
"Yes" before the program ends. Right now, I've tried catching the
FormClosing and FormClosed events. The message box appears at the right
time, but since the form is already closing, it doesn't matter if the
user presses "Yes" or "No". how do I cancel the FormClosing?

Is it possible to use some C or compiler extension to catch
integer overflow?
The situation is as follows:
I use C as target language for compiled Seed7 programs.
For integer computions the C type 'long' is used.
That way native C speed can be reached.
Now I want to experiment with raising a Seed7 exception
(which is emulated with setjmp(), longjmp() in C) for integer

Hi there,
I am trying to reuse a piece of code that was designed as an
application. The code is covered with 'exit' calls. I would like to
reuse it as a library. For that I renamed the 'main' function into
'mymain', but I am stuck as to what I should do for the 'exit'.
AFAIK there is no portable way to catch the exit. The only thing I
can think of is atexit, but that does not work since 'exit' is still
called afterward.

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:

Overview:
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,...
