These questions apply to std vector, map, and cout:
I am uncertain of the thread safety for reading/writing
for std templates. I know if all threads are reading
concurrently, it is thread safe. However, I have this situation:
Case 1: map

Hi,
I have a problem about thread related exception handling.
I created a background thread to fill a DataTable in a Windows
Application. Inside the code, I have
foreach (…)

Hi,
The documentation states that enumeration through a collection is
inherently NOT thread-safe, since a thread which added/removed an item from
said collection could screw up the thread that was iterating. That makes
sense.. but... given a collection that is filled at start-time and never
modified again, is it safe to have multiple threads *reading* (not writing
to) the collection using foreach()?
I have a class that exposes an...

Hello,
I am writing a program in Visual C# and I have encountered a problem.
In my program I want to dynamically create a multitude of controls (thousands) on a form. The problem is that calling the Controls.Add() method several times or even calling the Controls.AddRange() method once can take a huge amount of time. Therefore, I would like to be able to run the loop that creates the controls on a different thread and meanwhile give the user...

My application uses a singleton static class for writing entries to a log
file. The location and name of the log-file is read from web.config each time
an entry is written, but has the current date inserted into its name. For
example, the string:
c:\inetpub\wwwroot\myapp\log.txt
will be changed to:
c:\inetpub\wwwroot\myapp\log_20060216.txt

I have a class that instantiates two Timer objects that fire at
different intervals. My class can be instantiated within a Windows
Form or from a Windows Service. Actions performed by one of the event
handlers may take longer than the interval for either of the timers,
so it's possible for multiple events to fire "simultaneously" and for
events to queue up. I'm attempting to get the timers to sync on some
reference type object, or use...

Don't see any official notice that compiled library dll's loaded in the BIN
directory of an asp.net website need to be thread safe, but concurrent visits
to the same web site sure bear this out. Does anyone know the answer to this?

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...
