Hi all
I write a program to detect key press,but , why there is a *space*
before the character I typed.??
#!/usr/bin/env python
import sys
import tty
import termios
i = sys.stdin.filen o()
o = sys.stdout.file no()
backup = termios.tcgetat tr(i)
def loop():
while 1:
ch = sys.stdin.read( 1)
print "->%s"%ch
if ch == 'q':break
try:
tty.setraw(i)
loop()
finally:
termios.tcsetat tr(i, termios.TCSADRA IN, backup) 3 7954

Puzzles me too, but I know this is really easy in Curses (on top of
that, it isn't specific to Linux; curses works on many terminals) http://www.amk.ca/python/howto/curses/

There is none. The output I see when I type 1 2 q is:
->1
->2
->q
If that is what you see, the problem is in your
print "->%s"%ch
statement. It implicitly outputs '\n' at the end, and when terminal is
set in raw mode, this is not translated into '\r\n' as when terminal is
in canonical mode.
Try
print "->%s\r" % ch
or just
sys.stdout.writ e(ch)

Hi all,
I am becoming a little stressed with the age-old problem of detecting when a
user types (for example) a quote character ("). On a UK keyboard, I can look
for a 2 + shift mask; on US, single quote + shift mask.
I don't want to have to know every single international keyboard layout just
to know when a shifted character has been entered. If anybody has any ideas
to share, I'd be very grateful!

Hi,
I have a problem that I have been working with for a while.
I need to be able from server side (asp.net) to detect that the file i'm
streaming down to the client is saved completely/succsessfully on the
client's computer before updating some metadata on the server (file
downloaded date for instance)
However,
All examples i have tried, and all examples I have found that other people
says works - doesn't work for me :-(

Hi everybody, does anyone know how to detect a key press from a
keyboard. Well I do know how to do that, but i need to detect just one
press and ignore the others. I mean, my program checks an input from the
outside (a sensor) and i emulate that signal as a keypress, but the
sensor doesn`t send the signal as a unique pulse y just keeps sending
signal during some seconds, so that is like to be pressing one key for a
period of time. How can...

Hi all,
I am writing an application to detect the dead pixel of LCD panel by using
visual C++ (MFC). My flow is follow:
1. Display a dialog with a start button. When the user press the start
button. The whole screen become black colour.
2. When the user press any key by keyboard. The whole screen changes to red
then green, blue and white.
3. The screen back to "normal display".

In most modern distributions of Linux and Unix (at least ones with graphical environments like KDE, Gnome or XFCE), you get to mount your partitions easily from the desktop. In some cases however, it isn't that easy.
Note, that all of these commands have to be run in a terminal as root user. To open a terminal (sometimes called a console), either press ALT+F2 and type xterm (alternatives could be konsole or terminal) or press CRTL+ALT+F1 to...

C/C++ Programs and Debugging in Linux
This tutorial will give you a basic idea how to debug a program in Linux using GDB. As you are aware Visual Studio doesn’t run on Linux so you have to use some of the tools provided on the command-line. If you hate the command line tools, get over it since you’re bound to be using them at some point in your career. All commands in Linux ARE case sensitive so capital letters are different from lowercase...

Compound question: first, and this is not easy, if there's a way to
detect multiple simultaneous key presses in C# let me know (in the
below code, keys c and d being pressed simultaneously or nearly so).
I researched this and for C# (as opposed to MFC) there is no library
function, and no easy way, though some code on the net suggested that
you set up a thread that 'lives' for a certain time, then, if keys are
pressed in that certain...

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.

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,...
