I am trying to determine if C# has the capabilities to listen for system
events when the application does not have the window's focus.
I am writing a windows application that I would like to run in the
background when I am using my computer. I would like this windows
application to utilize the clipboard, and determine when data has changed on
the clipboard. I would also like my app to listen for Ctrl+C and Ctrl+V
events, as well as mouse...

Howdy,
I would like to get down to the nitty-gritty of the keyboard's operation.
Specifically, I would like to poll only a few keys on the keyboard, and I
would like to know when more than one key is pressed. In other words, I
would like to know how to access the keyboard's scan lines, so that if, for
example, the user is holding two of the arrow keys pressed simultaneously, I
will get a continuously changing response of...

I am writing a multi-threaded program with a worker thread. I want the rich text box to auto scroll down as the text is added.
Here is what I want to happen:
From the worker thread:
1. Add the text to a richtextbox named txtMessageBody.
2. Make sure that the scroll is to the bottom of the box.
3. Put the focus back on the box where the user enters text
This is from a basic messenger I am writing.
The problem only occurs when trying...

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...

Does anyone know how to detect keypresses in a Datagrid cell? The
Keypress event ofthe datagrid doesn't fire if you are in a cell.
Neither does KeyUp & KeyDown. I've tried hooking in to the
DataGridCell events but it doesn't have the keypress event.

I'm trying to setup a mechanism whereby I store a formatting code in the Tag
of a textbox. This code might be "UpperCase" or "LowerCase" or "NumericOnly".
I've been trying out various code in KeyPress and KeyDown but haven't been
able to figure out exactly what to do to intercept the keypress and modify
the code accordingly.
So for example, if "UpperCase" is in effect and I receive an "a" then I will
turn it into an "A" on the fly.

Hey everyone!
I'm not very good with Tk, and I am using a very simple canvas to
draw some pictures (this relates to that nokia screen emulator I had a
post about a few days ago).
Anyway, all is well, except one thing. When I am not in the program,
and the program receives a draw command (from a FIFO pipe), the canvas
does not refresh until I click into the program. How do I force it to
refresh, or force the window to gain focus? It...

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,...
