Hi all,
I was wondering if you could help out with this problem that I am having.
What I am trying to do is detect keyboard input in a while loop without
halting/pausing the loop until the key is pressed (without hitting return).
I looked at serveral faq's on the net and installed the cspan readkey module
and neither seems to work most likey its me since I am getting frustrated.
but anyway here's a sample code.
while (1) {

Hi!
What is the best way to check whether a key is pressed without blocking
in C++?
I know I can use cin.get(c) to get a character from standard input, but
this blocks.
And I know _kbhit() exists in MSVC++, but that's in <conio.h> and
probably not standard, is it?

Have read the FAQ's and the forums but still cant find a good solution
to this. I am using Linux and G++. I am trying to run a program which
computes something or other and have the ability to detect when a key
is pressed to make the program output its current reults. I.e. The
main iteration runs continuously the user can press 'o' say at any
time to output what it has.
At the moment I am looking at using a separate thread to handle the...

Hi,
How do I read a char from stdin before the '\n' is pressed?
for example I know that I can use getch() to read a single char from the
user input, but suppose I wanted to read before the carriage return is
pressed.
for example I type a char and the following actions is done before the
'\n' is pressed.

Is there any way to make cin behave like getch()? Specifically,
getch() returns immediately after a key is pressed and the cin family
of input methods seem to block until a new line is encountered. I need
some help.

My doubt is on the working of getch() function based on the following observations
1) if the pressed key has an ascii code,only that can be read using a single call to getch()
2) if the key has not an ascii code then the first call to getch() returns a zero and ,if we made a second call, it will return the scan code with out an additional key press.
Some one please help me to understand getch()

In the following code something strange happens ! If I keep pressed any
of ALT+Arrow, keys, they are extracted two times from buffer then getch
seems to stop; if I release and press again ALT+arrow nothing changes:
the only way to exit from this condition is press another key a single
time.
What seems to happen is that kbhit say some keys are present in buffer
but for getch don't see any data and waits for a key. Why this happen ?
If I...

You are probably thinking "Another Fool! He doesn't even know how to get what keys are pressed. Use getch()". You might think so, but i need to get the keys pressed without having the console active, i mean, imagine i am surfing the internet and write "http://thescripts.com". I want my program to know that i have typed in "http://thescripts.com", but the window i am typing that into is the Internet Explorer Window, so it's not that easy......

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
