Hi all,
I am developing in Python (as a GUI I choosed Qt).
To increase my expertise, besides reading manuals & tutorials, I am
studying a big program developed in the language of my choice, and
related with my project (to develop a card game).
For that reason I choosed PySol (also if the GUI part uses Tkinter and
not Qt).
PySol is made up from almost 100 python modules and for that reason
you need a mean to organize that. I developed...

Hi,
Does anyone here have a strong understanding for the meanings of the
terms "lvalue" and "rvalue" as it pertains to C, objects, and different
contexts? If so please share.
I've been reading several old posts/threads on the subject, and they
never end with a conclusion (people keep correcting each other and
disagreeing).

We have service oriented architecture
that comprises of a number of Win2k/IIS boxes.
Some of these web service applications access an AS400
system for data acess (We are using HitSoftware's Ritmo .net
native driver). For fail over we route these requests
through a hardware based load balancer (BigIP).
The BigIP allows us to fail over to a secondary AS400 system
in case the primary one fails.

What is the best practice for querying, inserting and deleting from a SQL
2000 database from high traffic ASP.NET web forms? Is it to have the
SqlConnection & SqlCommand object initialized and stored globally in the
Application object, or is it to dynamically create and destroy them with
every visit to the web forms? I am seeing a serious problem with
performance when I got to over 1000 users consecutively. I estimate a usage
of over...

Two network load balanced (using Microsoft NLB software) webservers
with session maintained in a SQL Server database. NLB is configured
with no affinity settings and two network cards in each machine.
Machine keys are identical on both webservers. There is no anti-virus
software installed. SQL Server database is storing session information

I wasn't sure if this was the best place to post since there isn't
really an algorithm section for programming. I was curious that if
you're given a MST tree of G and P is the shortest path between two
nodes s and t. If we increaset the cost of each edge of G by some
amount x, would P still be the shortest path between s and t, because
all the values are incremented by x amount or would it change?

I am having a problem with the TreeView control. What I am trying to
do, *should* be simple.
When the user selects a node in my TreeView, I first check to see if
the data for the object referenced by that node has changed. If it has,
I want to give the user the option of either selecting the next node in
the tree, or canceling, in which case the next node is not selected.
The tree remains as it was, with the original node selected. (I...

Hi all,
I'm creating a number of fragments to calculate various presence numbers. I'm creating variables from the results of these fragments then doing simple math to give the results.
I'm having an error when trying to add two variables (from the result-tree-fragment) when one variable has no value at all. In the source XML, the criteria returns no matches, so when the two variables are added, it returns NaN. I'm Trying to make a...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
