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:

Given the typical following code:

}
In a "clean" fashion, how is it possible to add custom data (to be
subsequently accessed) to the Event instance? By custom data i mean
practically anything, from a class to a single int. Particularly to my case,

Hi!

This control is then added to a form( myMainForm)
Now, whenever something is dragged and dropped onto myDrawControl , I want

been added.(ArrayList objectsAdded)

I've created a custom control based on TreeView and it handles several
events, such as Mousedown. I added this custom control to the toolbox in
another project, dragged the custom control to the form and everything works
as it should with the custom control responding to the mousedown event.
I also want to respond to the mousedown down event occuring in the custom
control inside of the form containing the custom control. Does anyone know...

Hello all,
I've created a custom control that draws a monthly schedule (using the Draw
function in C#). Basically it draws 31 boxes and writes the day number in
every box.
This works great. But I now want to show a different tooltip for every day.
For now I found out that I can add a tooltip for the entire custom control

OK.. phew. Playing with data grids for the past few days has been fun and a
huge learning experience..
My problem. I have a requirement to display a gird with a gird. Within the
embedded grid, theres a requirement to show a drop down menu list (this is a
control I downloaded online) in one of the columns. For the purposes of this
question, Ive implemented the drop down menu as a drop down list instead.
Ive got all this working at this...

I am using VS2005 to build a web form dynamically.
I'm using AddHandler to connect a custom event handler to the TextChanged
event of dynamically added textbox controls. Data entered in the
dynamically added textbox controls is saved to a database in the custom
event handler.
The custom event handler fires when the page posts back. I have a menu
control which causes a postback, and the custom event handler then fires if

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...

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...
