Hi,
A question about how to execute a system command from python program. e.g.
in a python script, I need to run another program written in C++, and after
that come back to the same python program.
Is it the system module, and which function do I use to do this?
Thanks a lot
Catherine

Hi. I'm writing a command shell that reads commands from standard input.
At this point I have the command in a std::string. Now I want to execute
this command in the shell. From the Borland newsgroups I learned that there
is a function in stdlib.h called system.
int system(const char *command);
First question, is the system command ANSI compliant. Because I include
<cstdlib> and write std::system(command.c_str()); it looks like an...

I would like to redirect the output from os.system to a variable, but
am having trouble. I tried using os.popen(..).read() ...but that
doesn't give me exactly what i want.
...this is windows by the way.
For example:
tmp = os.popen("hostname").read()
....works as expected.

Hello all.
I have a python script here which is just a wrapper for 2 or more system
commands. I would estimate the program spends at least 95.5% of 'real' time
running the system commands.
I want to trap the key combo and exit (somewhat) gracefully if the
user decides to abort the program. I am using os.system for the system call,
and I have wrapped the entire main loop in a try: except KeyboardInterrupt
statement to try to...

I have an issue trying to execute commands in a web service. The command
starts under the specified user. However, it never completes its execution. I
can execute simple commands like "echo HELLO" and cmd.exe starts but never
terminates. I'm relatively new to .NET, so I may be forgetting some thing
obvious. Thanks! Here's the code:
using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

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

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,...
