This may be the wrong group but I didn't see anything for VC++ so I'm
trying here.
I have a C++ book by Deitel and Deitel that says I can use fstream
File("data.dat", ios::in | ios::out | ios::binary) to declare a file
object with read/write modes turned on for working with binary data.
I've tried this and my file is not created. The only time it is created
is when I specify ifstream or ofstream but not fstream. I've tried
removing the...

I am rewriting a C++ application in C#. This file has a combination of Text
and Binary data.
I used CFile before to read the text. If I hit a certain string that
denotes the following data is binary, I used the current position in the
file and another stream to read to the binary data.
All text data is ended with a carriage return / line feed while the binary
is actually an image file listed byte by byte. Preceding the binary data...

i'm trying to read a file byte by byte (and later alter the data and
write it to a 2nd file byte by byte) and running into a problem where
it seems to keep reading the same byte over and over again (an endless
loop). i thought that BinaryReader.ReadByte advanced to the next byte?
i had it time out after 1000 iterations, and keeps outputting the same
byte. any help appreciated, my code is below:

Hi,
I came from delphi world and now I'm doing my first steps in C++. I'm
using C++builder because its ide is like delphi although I'm trying to
avoid the vcl.
I need to insert new features to an old program that I wrote in delphi
and it's a good opportunity to start with c++.

I'm using the zipfile library to read a zip file in Windows, and it
seems to be adding too many newlines to extracted files. I've found
that for extracted text-encoded files, removing all instances of '\r'
in the extracted file seems to fix the problem, but I can't find an
easy solution for binary files.
The code I'm using is something like:
from zipfile import Zipfile
z = Zipfile(open('zippedfile.zip'))

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,...

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...
