I have an application where I need a very simple database, effectively a
very large dictionary. The very large dictionary must be accessed from
multiple processes simultaneously. I need to be able to lock records
within the very large dictionary when records are written to. Estimated
number of records will be in the ballpark of 50,000 to 100,000 in his
early phase and 10 times that in the future. Each record will run about
100 to 150...

In Project settins - C/C++ - Code Generation,
what is the difference between the option
"Multithreaded" and "Multithreaded DLL".
I understand that on selecting multithreaded option,
single and multithreaded applications can both use that
dll, but what about multithreaded DLL option.
Thanks

We have a multithreaded app that responds to events, and writes these
events to a text file. This text file is used by an external system
for further processing.
We want to be able to write multiple entries to the file, and then
rename it and copy it to a new location when the file reaches a
certian size, or a certain time span elapses (which ever comes first).
I have created a static/shared timer member variable in class that

Okay, here is what's happening:
I have a reasonably fast laptop (1.4 GHz Mobile M, so comparable to 2.5GHz
P4) doing .net development.
Running Windows XP pro, SP2
IIS is installed and running fine
All SQL Servers I am referring to share a small (10 computers or so) LAN
with a 100MB Switch.
No other computers on the LAN exhibit this problem.

Hi,
I am working on converting Informix database to Postgre. I have one
question for fetching records using PostgreSQL. The record I am fetching
is a variable size text string. Before fetching the record, a
preallocated static buffer size will have to be declared beforehand in
the declaration section. Since the record sizes vary a lot, instead of
using the static buffer, is there a dynamic way to fetch these records?

Hi all,
I've recently ported a rather large C application to run multithreaded.
A few functions have seriously deteriorated in performance, in
particular when accessing a rather large global array, that contains
information that is shared among threads.
Any idea, why the lines accessing this global array now take about 50x
longer in the multithreaded application?

I have a multithreaded application that I now want to convert into a Windows

to take into consideration when creating a multithreaded windows service as
opposed to a multithreaded windows forms application?

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...
