error all the time, I've been looking in MSDN for a couple of hours with no
luck, no idea, it's my first program, if you are so kind and could explain
me in detail.
Sorry for my english.

Hi, I'm getting an exception that really has me stumped. It's sporadic
at best, it's only happened a handful of times.
This particular time it happened when the user pressed 'Alt-S' to save
the data that they were entering.
Following is all exception information.
Any thoughts much appreciated.
Cheers

Hello,
I am trying to find a way to tell if an .NET windows forms Button
(System.Windows.Forms.Button) is "depressed" (pushed down). For my
application, I can not use a check box control set to button style, I
must use a System.Windows.Forms.Button. I can not find a way to tell
when it is momentaraly pressed.
I tried calling the API SendMessage with the button handle and
BM_GETSTATE to get the state of the button. This will only return...

Hi All,
I tried creating a C# Form using Petzold's "Programming MS Windows with C#"
guidance. He recommended using the namespace System.Windows.Forms.
However, VS.NET claims "the type or namespace name 'Windows' does not exist
in the class or namespace 'System'."
But I read it, MSDN seems to think it's fine at

Hi,
I am relatively inexperienced with VB.Net, but I am familiar with many
concepts from programming; I have some basic level of competence with C/C++
and Perl, but I just started using VB this morning.
I am trying to write an .exe file that is essentially a script. It will
open an application, send it some commands via the keyboard, then wait for
the results and close the application.

Hi, if someone could answer this please I would be grateful - I have
looked online but can't find the answer.
In C# I can do this for example
m = new System.Windows.Forms.Form()
but of course in VB.NET the same would be wrong
m = New System.Windows.Forms.Form()

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...
