Here's a little test app to demonstrate a problem I'm having.
It creates four buttons, each one with the different FlatStyle types
available. Three of them behave exactly the same way(and the way I'd
anticipate), but the FlatStyle.System one does not.
If you click on any of the buttons, use the enter key, or the
spacebar, they will bring up a messagebox that says "Activate".
Except the FlatStyle.System one, which will bring up _two_...

(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,
I am wondering why the .NET Framework is quite different from Win32 API when
it comes to displaying system modal message boxes.
Consider the four following types of system modal message boxes (please see
associated source code below):
1) Win32 API with context ("btnWin32WithContext_Click")
2) .NET Framework with context ("btnFrameworkWithContext_Click")
3) Win32 API withOUT context ("btnWin32WithOUTContext_Click")

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...
