Hi all.
Handling files is an extremely frequent task in programming, so most
programming languages have an abstraction of the basic files offered by
the underlying operating system. This is indeed also true for our language
of choice, Python. Its file type allows some extraordinary convenient
access like:
for line in open("blah"):
handle_line(line)

Hey folks,
I have a question regarding file handling, and the preservation of class
structure. I have a class (and I will post snippets of code later in the
post) with both primitive data structures (ints), and more complex data
structures (strings and vectors) in it, and would like to write the entire
class to a data file that could then
be read back and loaded.
However I'm having difficulty with this -- I found out (due to an...

I'm fairly new to doing involved file i/o and I came across something
weird with a program I'm writing (modifying MIDI data, if it makes any
difference). With some input files, when I modify data and then output
to a new file, the program will crash. The catch is that when I open up
the output file to see what the program managed to write, it always
makes it to an offset of xFFF.
For example, with one file it crashed at 2FFF, another at...

Hi,
I'm writing a windows service which interacts with a separate process.
Basically, it calls a process which creates a file, and then my service
reads that file. The problem is, the external process can take a second
or two to finish writing the file. If I try to read the file to soon, I
get an exception that "The process cannot access the file because it is
being used by another process".
I could just set a timer, but the time it...

I need help in implementing proper error handling.
I am trying to upload a file based on the sample code below. The code works
well except if the file selected is too big.
I do know about the maxRequestLength parameter of the <httpRuntime> section
and that works as expected. What I want is to enforce a max file size but
haven't been able to trap the error thrown when the file is too large and
that's where I could use some help.

Hi,
I'm using PHP 4.4.4 on Apache 2 on Fedora Core 5. PHP was installed
using Apache's apxs and the php library was installed to
/usr/local/php. However, when I set my "error_reporting" setting to be
"E_ALL", notices are still not getting reported. The perms on my file
are 664, with owner root and group root. The php.ini file is located
at /usr/local/lib/php/php.ini. Any ideas why the setting does not seem
to be having an effect? ...

I fixed a bug today that went against my intuition. I am on Linux.
I had a class that fopen'ed some files. When I called delete
on these objects, I expected that the files would be closed
automatically, just as when an application terminates, but
evidently this is not the case. I guess I have to fclose the files
in the destructor.
Is this a correct assessment?

First of all I am very new to c++ so please bear with me. I am trying
to create a program that keeps an inventory of items. I am trying to
use a struct to store a product name, purchase price, sell price, and
a taxable flag (a Y/N char) and then write this all out to a file
(preferably just a plain old text file) and then read it in later so
that I can keep a running inventory. The problem that I am running
into is when I write to the...

Assumptions
I am assuming that you know or are capable of looking up the functions I am to describe here and have some remedial understanding of C++ programming.
FYI
Although I have called this article “How to Parse a File in C++”, we are actually mostly lexing a file which is the breaking down of a stream in to its component parts, disregarding the syntax that stream contains. Parsing is actually including the syntax in order to make...

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.

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...
