Hi all
I am creating a basic control to perform some tasks, and I want to declare
some events to be raised so they can be handled from the form that the
control is on. I can create my own Event Handler class and use that, but I
would like to use the System.EventArgs class so that my event can be handled
by different controls.
For example:

What advantages do I reap by following the EventArgs pattern in defining
custom event delegates?
For example...
public delegate void CustomEventHandler(object sender, CustomEventArgs e);
public class CustomEventArgs : System.EventArgs
{
int index = 0;
public CustomEventArgs(int Index)

Why do I get a System.NullReferenceException for this script?
I added the following script to a simple form with a button.
<Script>
public event EventHandler DoThis;
static void Main()
{
Application.Run(new Form1());
}
private void button1_Click(object sender, System.EventArgs e)

I have a 3rd party object that fires an itemchanged event when someone edits
some data on a form. This event has a custom eventArgs that has a field
called ActionCode. In the code of the event, if you set this ActionCode to
various values the control will respond in various ways (reject, reject
change field, accept, etc). I am trying to understand exactly how that
works as I am trying to extend the control and add more processing s...

Hi,
When we create customEventArgs, we also derive the classes from
eventArgs( ) and I dont understand the advantage of this inheritance.
This is neither an interface nor applied as attribute.
I have seen similar stuff in remoting also where we derive from
marshallByRef object in SAO to create transparent proxy. I don't know
how it creates transparent just by inheriting from base class.

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....
Now, this would greatly impact the work of software developers. The idea...
