Hi
I have a textbox which displays a formatted numeric. eg: 100,000
When I retreive this value for calculations, it is valued at 100
eg:
calc = val(txtbox) * 2
calc will equal 200, not 200,000.
Why is this, how do I fix it ??

Okay, i've got a file open, call it infile. I've got a simple while(!eof),
but say the first line of my file is "<?xml version="1.0">", then it takes
two iterations to get the string. first 'line' is "<?xml", then 'line' is
"version="1.0"", what's happening that I need to change the behavior of so

I'm still not completely sure what's going on with C++ I/O regarding the
extractors and inserters. The following document seems a bit inconsistent:

Copying a file:
WRONG WAY:
#include <fstream>
std::ifstream IN ("input_file");
std::ofstream OUT ("output_file");

Hi
I am writing a code to open a space delimited data file, return the
number of rows and columns, as well as return the nth column where n
is user define number.
I put all the cells in a loooong vector and loop in an incremental way
to select the column of choice, here is the code which works but gives
a warning

My data is in a big file that I have no control over. Sometimes its
over 30 MB and often there are several of them.
It is machine generated and is nicely formatted. Example text follows:

= 20,
= 1,

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...

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...
