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...

Hi,
in my application I want to react to certain keys when a context menu
is showing. So I installed a keyboard hook, but now whenever a key is
pressed when the menu is showing, the application crashes and sometimes
throws a NullReferenceException in system.windows.forms.dll. I assume
that the hook somehow messes up the context menu's message loop or
something like this. I also had this problem with a mouse hook, so i
guess its a...

I have a Windows form application running that contains a button and textbox.
An easy thing to do is to monitor the last time a keystroke was executed in
the textbox. I can then click the button and it will say: "The last
keystroke in the textbox was 10 minutes ago."
This is not what I want to do. What I would like to see is a message that
says: "The last keystroke in any running application on this computer was 23
minutes ago."

hello all,
I am working on a project related to Internet Explorer. I want my
application to be invoked by a keypress( single key stroke or a
combination). But this must get invoked only when the IE browser is
open. I learnt that SetWindowsHookEx must be used along with few
others. But my doubt is how to call my application? Can i implement the
keyboard hooks related methods in the same project as my application or
should this be else...

hooks globally whenever IE is opened.The keys that are pressed when IE
is active are to be captured.I am trying to check whether the IE is

the flag is set, the keys are sent for further processing.The keyboard

I have an application that minimizes itself, and I want it to listen
for certain key commands, and when they are pressed, my program can
react to them.
So far I've gotten my application to react as I intend while the
program has focus, but when the application loses focus, the listening
stops.
I am using VS 2008 beta 2, with .net 3.5.

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...

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,...

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...
