Hi.
I'm reading a 5 meg (or so) file from the response stream of a WebRequest,
and it's pitifully slow. I mean *really* slow, in the order of 15 minutes to
download. Now obviously I'm caching this on the client (Windows app /
IsolatedStorage), but I can't have it taking this long to download in the
first instance. We've got Gigabit LAN. what's the bottleneck?
I could make the resource available via a different protocol / means if...

Hi,
I am fairly new to C and all the C books I got talk about gets() but when
I compile it says I should not use gets() because it is dangerous. I
understand that it is dangerous because it doesn't check whether there is
more characters entered by the user the what can be stored but I don't
know what the safe equivalent of gets() is.
Below is an example program I have written. (GCC is my compiler on
GNU/Linux system.)

All,
I believe I am having a threading problem. Class "BELights" is part of a
larger DLL that is used by my main application. A user control (of type
BESeat) within the main application raises an event and attempts to execute
the "StartTiming" method of BELights. The method does not execute which
leads me to believe that BELights is not thread-safe. (Or is it the user
control that is not thread safe?)
When an event fires for...

Hi
I have a situation where a method is fired from receiving a message from my
server.
On receiving this message it triggers a visual animation.
So what happens when the server sends say 3 messages in quick succession.
I want the method to fire, animate completely, and then fire again, finish

I have a device in the field that I access by the stream method.
I open the Stream and do the following:
1. stream.write a character to the device.
2. stream.read the information from the device.
The problem is that when I am debugging and step through the code there is a long enough pause that I recieve the entire string. If I just run it, I only get the 1st character. I have attached the code below.

Hi all,
I am filling up a class by reading a binary file.
I have a Read(std::string& name) method that opens the file and reads
the inside.
The first few lines of the file contain some text describing the size of
the data that follows; imagine that the file contains some images and
this first line tells the size of the images and their number.
Having this info, what I do is to call a function Init() that allocates

SUBJECT: How to make this program more efficient?
In my program, a thread will check update from server periodically and
generate a stl::map for other part of this program to read data from.
Let's name the update method as doUpdate and stl::map read methods as
getData and copyData.
Since stl::map is not thread-safe, we should do synchronization by
ourselves. A usable solution is to create a boost::mutex::scoped_lock
object in all above...

I have a fully-portable C program (or at least I think I do). It works
fine on Windows, but malfunctions on Linux. I suspect that there's
something I don't know about the standard input stream that's causing
the problem.
Here's how I wrote the program originally:
#include <stdio.h>
#include <string.h>

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...
