Hi,
I installed a Apache 2.0.47, PHP 4.3.2 and MySQL 3.23.38 on windows2000 and
I installed a forum on which I enabled the feature to upload files. Together
with some friends of mine I make music and they all travel alot, so a forum,
on which we could chat ánd keep in touch with our family and at the same
time upload our newly created music seemed a good solution, only the problem
is, MySQL doesn't seem to be able to handle files bigger...

I'm using the stringstreams to get the numerical values of string
tokens (the strings result from tokenizing a line of input elsewhere):
#include <iostream>
#include <sstream>
using namespace std;
int main(void)
{
istringstream iss("1.23DOG");

I know that this has been posted before on several other newsgroups, but I
need to make sure I got this right, so I hope you can forgive me for
posting this.
In MVSC6.0, and also in several Borland c++ compilers from what I can see
from newsgroup postings, ifstream::tellg() alters the position of the file
reading pointer when reading UNIX files (only LF character, not CRLF) in
text mode. I can see why it does this, keeping consistency...

Is the any reason according to the standard that calling tellg() on an
std::ifstream after a call to peek() could place the filebuf in an
inconsistent state?
I think it's a bug in the VC7 dinkumware implementation (and I've
reported to them as such), but the following code
std::ofstream ofs("test.txt");
ofs << "0123456789";
ofs.close();
std::wifstream ifs("test.txt");

I am reading in image files in a program and I read in
the header in ascii mode. The problem is, sometimes tellg
() gives me a completely incorrect result and sometimes
it is just fine. Here is an example:
char input;
std::ifstream fin("blocks.pgm", std::ios::in);
std::ifstream::pos_type position = fin.tellg();
fin>>input;
position = fin.tellg();

quite annoying because there is no other good way to read

since it works just fine when I compile it using g++ on a
Linux system. Here is an example:

Hello!
This is my first time dealing with Very Large Files.
I have vector of strings representing numbers and I need
to extract bytes in binary mode from a Large File that
correspond to ranges specified by the strings. For example
for an input of
"0", "100", "500", "700"
I need to create three files, the first would contain

Hi,
I am reading a big file , and need to have a flag for current file
position so that I can store the positions for later direct access.
However it looks tellg is a very costly function ! But it's code says
it should just return the current buffer position , thus should be a
very low cost function.
To explain,
{
boost::progress_timer t;
std::ifstream in("Y:/Data/workspaces/tob4f/tob4f.dat");

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...
