What are the most popular, and well supported, libraries of drivers for bar
code scanners that include a Visual Basic and C/C++ API? My requirements
are:
- Must allow an application to be written to a single interface, but support
many different manufacturers' barcode scanning devices. I do not want to
be tied to one manufacturers' software interfaces.
- Must support use of the scanner from Visual Basic, and ideally from C/C++
and...

I posted yesterday about a project I'm involved in to build a login
application using a barcode scanner.
I've solved most of the problems, but one remains. The client want to
disable keyboard input (except at some remote sites where there won't
be a scanner). The session "knows" whether that site should be
keyboard enabled, but unfortunately the output from the scanner is in
the form of keypresses! So any attempt to capture and...

Hi all,
I have an application that uses input from a barcode reader via a USB
port. My application works fine only if the application HAS FOCUS.
If the user opens up another application (not mines) such as
notepad/word, etc, the Barcode Reader reads data into the applicaton
that currently has focus with is notepad/word but not my own
applicaton.
My question is as follows: Is there a way to write a Listener

I'm working on an application (OEM) using c# that uses input from a keyboard
and a USB Barcode Scanner.
I need to be able to identify keystrokes from the barcode scanner and remove
them from the message queue, regardless of what application has focus.
I can identify the keystrokes and input device by registering for raw input
(RegisterRawInputDevices) and processing the WM_INPUT message. This gives
me the keystrokes and the ability to...

Greetings,
I would like to integrate a barcode scanner into the current project I
am working on. I have been looking around teh web and with the
exception of embeded devices I cannot find many programming guides.
What I am looking for is a barcode scanner with an api/sdk. I am not
interested in using a keyboard wedge because I do not want my end user
to have to deal with making sure the cursor is in the right place.
As it needs to...

Hi,
I am in the design phase of building a database that will track the
productivity of my warehouse. I am thinking of using a barcode
scanner to assist me with this. Employees will hopefully be scanning
a barcode which will communicate to the computer that the employee did
some type of task. Employees will be identified by ID badges which
will contain string data to identify them and hopefully log them in.
Is this a good way to keep...

Hi
I have created a website which has a number of buttons on it which allow users to add items to there basket, they then click on an AJAX watermarked textbox to set focus before using a keyboard wedge scanner to scan there staff ID card, this causes a postback and validates the user - all works perfectly.
My problem is caused if the user attempts to scan their card before clicking on the watermarked textbox. This then forces a postback...

Does anyone know of any python based barcode readers? I'm looking for
something (commercial or open source) that will use some OCR algorithm
to read barcodes from an image or ps/pdf file, and ideally will be
something along the lines of a callable python script. I have some
pretty simple needs, i'm only trying to read code 93 barcodes, so i
don't need it to be able to identify multiple symbologies or
anything. Any suggestions would be...

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...
