Hello,
I vaguely remember reading in the manual that the order of the retrieved
rows in a response to a select statement is unpredictable (unless you
use an order by clause). this possibly depends on the indices set up for
the table and/or used in constructing the result etc. is this accurate?
if so is there any way to insure that rows retrieved are returning in
the order by were inserted in, say other than ordering by some
'insertion...

Having problem with retrieving a class instance item from a Vector.
This is the result of the code below.
Also a weird note: If I dont declare as:
TYPE_VECTOR_BANKED_MEMORY_DATA
bankedDataMemoryLayout(NUMBER_BANKS);
but an empty vector
TYPE_VECTOR_BANKED_MEMORY_DATA bankedDataMemoryLayout;
The program crashes on the 3rd insertion???

Problem:
I am fetching data from the database, storing it in a
dataSet, and binding it with a Data Grid. The DataGrid
controls allows sorting. The problem is that when the data
is sorted on one of the columns in the Data Grid, and I
then try to retrieve the selected row using
the "SelectedRowIndex", I get the row as per the original
order of data.
Eg: If the order of rows is: C - A - B, which after
sorting becomes A - B - C. Now, if I...

I am trying to sort a linked list using insertion sort. I have seen a
lot of ways to get around this problem but no time-efficient and
space-efficient solution. This is what I have so far:
struct node
{
int x;
struct node *next;
};

I am trying to write a conatiner which has std::map like methods but
preserves the order of insertion.
TO achieve this I thought of providing my own function for comparing
the keys of the map. Following is the sample code for this:
template <class T>
struct my_compare
{
bool operator () (const T&a, const T&b)

Hi,
I'm playing with dynamic script insertion to make a request to the
server for a JavaScript file to be automatically run when it arrives
in the browser. It works but...
The page caching is too good. When I revisit the page or refresh the
page, and then redo the script insertion, the browser doesn't even hit
the server to check for a newer version of the JavaScript file. The
same old script runs with each insertion.

One question which pops up frequently here at TheScripts is: 'How do I retrieve data from a Recordset once I've created it?' One very efficient, and not that often used approach, is the GetRows() Method of the Recordset Object. This Method varies slightly from DAO to ADO, so for purposes of this discussion, we'll be talking about DAO Recordsets. The ADO approach will be addressed in the following Tip. We'll be using a Query, consisting of 5...

Last Tip, we demonstrated the technique for retrieving data from a DAO Recordset, and placing it into a 2-dimensional Array using the GetRows() Method. This week, we will cover the same exact Method (GetRows()), but only as it applies to an ADO Recordset. Although there are similarities in the 2 methodologies, the ADO Method offers 2 more Optional Arguments, is a little more complex, and of course, the syntax is different in creating the...

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...

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
