I'm wanting to output a text header file in front of the data portion
of an output file. However when I use "\n" or "endl" as end of line,
it just puts a 0x0a in the file(which is non-printing)...in Windows
you need the (0x0d 0x0a) pair, if you want a new-line in a text
editor. What's the correct way to get this 2-byte sequence into a
file?
Thanks

This is long. Bear with me, as I will really go through all the convoluted
stuff that shows there is a problem with streams (at least when used to
redirect stdout).
The basic idea is that my application (VB.NET) will start a process,
redirect its stdout and capture that process' output, displaying it in a
window.
I've written a component for this, and a test application for the component.
It allows me to specify a command to execute,...

TcpClient has a method called GetworkStream GetStream();
So in other words, there is only one stream associate with it for input and
output, right?
So while it is receiving, it can not send, and vise visa, right? So will it
be a problem both server and client can initiative a sending action?
TcpClient only supports synchronous operation. What does "Synchronous" mean?
Means while it is reading or waiting for data to arrive from the...

I'm making an program that encodes text, and then writes it into
another text file. The problem is that I can't seem to get the "file
exists" checking right. If I use the command (coder is the
application):
coder something.txt an_exsiting_file.txt, then if I chose to overwrite
"an_exsiting_file.txt", an error message pops up, saying that to many
files are open <EMFILE>. Any help would be appreciated. Here is the

Hi, I am pretty new to python but i do have experience with c++. As a
part of learning exercise i wrote a python script to insert
beautifying comments(with name, problem...) to our lab program source
files (c language).
The script is working for most of the cases. The problem is i also
need to append the test output of the lab programs to the
corresponding source files(again the output should be added as a
beautified comment). The lab...

Hello all,
I have been having some problems with using Open CV to play an avi file.
I am currently creating a eye input based system, where the mouse is replaced by an eye tracker. I am currently working on flat .csv files, and importing the coordinates then using those coordinates to do various tasks on the screen.
These coordinates have been recorded using a real eye tracker which creates two files, a .csv file of the coordinates of...

hi, I'm a novice programmer trying to better define a hobby project
I'm thinking of.
What I would like to do is take a program and embed it or put it
within a Python-run GUI, using the GUI just to capture and send input
to the application, and display the ouput.
Specifically I want to use a Python module such as wxPython, pygame or
pyglet to build the UI, capture key presses, and then send a string to
the program, an interactive...

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...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
