Is there a way to use a keyboard listener in applications other than
applets?
I am trying to make a simple text editor that stores words in a
LinkedList, then checks each word in the list against a library of
keywords after a certain amount of time.
Must all the keystroke listening be done through the AWT or Swing, or
is there another way?

I have English Windows XP Pro and Office 2003 Pro on my computer. When I
enter data into fields of tables, queries and forms of Access 2003, it
automatically switches to Chinese keyboard input. Even though I remove the
Chinese keyboard input from Regional applet, the system will automatically
reinstall Chinese keyboard input when I enter data in Office 2003. After I
switch from Chinese keyboard input back to English keyboard input, it...

I'm working on an application (OEM) using C# that utilizes input from a
keyboard, and USB Barcode Scanner. The scanner is a HID Keyboard device,
and input from it is sent to the system as if it were a keyboard. I need to
be able to identify input from the scanner and keyboard independently. I've
looked at DirectX.DirectInput, and using user32.dll to hook into the
keyboard messages, but neither method seems to allow for identification of...

I've been trying to use _kbhit() but it didn't do what I thought it
would from books, "Detects whether a keypress is available for reading."
Herbert Schildt says,
"If the user has pressed a key, this function returns
true(non-0), but does not read the character.
If no keystroke is pending, kbhit() returns false (0)."
Here is the test code,

How can I duplicate the behavior of the operating system shortcut keys
in my application? For example, my windows form has 5 controls
(textboxes), the operating system will pickup which control has the
focus and handle ctrl-c, ctrl-v, or any other shortcuts. I have the
same shortcuts working in my app, but have not determined how to find
out which control has focus. Would I set up a loop or code for each
control at form level. Any help...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
