In java, this seems so easy. You need a new object
Object test = new Object() gives me exactly what I want.
could someone please help me understand the different ways to do the
same thing in C++. I find my self sometimes, trying
Object app = Object();
Object *app = Object();

We were testing a version of our app that's been running for months with no
problems and it started throwing "Object no longer exists" messages on two
machines in the test environment.
We tried the same test scenario on a production box: no problems. Tried them
on my developer box: no problems. In each of those two cases, the PC's were
connected to the same test server and *supposedly* had the same production build
image on them.

Hello,
This is a simple question for you all, I guess .
int main(){
double *g= new double;
*g = 9;
delete g;
cout<< sizeof(g)<<" "<<sizeof(double)<<" "<<sizeof(*g)<<" "<<*g<<" "<<endl;
*g = 111;
cout<< sizeof(g)<<" "<<sizeof(double)<<" "<<sizeof(*g)<<" "<<*g<<" "<<endl;

Hi,
Is there a standard for the global 'window' object in browsers? For
example, it supports methods such as setInterval and clearInterval, and
several others.
I know that w3c standardized several parts of the DOM, but this does
not include the window object.
Thank you

With the following code I can't understand why this.num keeps
incrementing each time I create a new instance of Foo. For each instance
I'm expecting this.num to alert as 1 but keeps incrementing.
Foo = function(type) {
this.num = 0;
this.type = type

I have Access 2000 and 2003 on my development machine. My client only has
Access 2000. When I develop for this client, I run Access 2000. However, my

As I result, on my machine they're listed as version 11.0, and then, when I
upload the file, they show as missing. So I have to go through the steps of

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,...

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....

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
