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'm developing a fairly simple user control that has two textboxes for
date/time entry (a from date/time and a to date/time). One of my
requirements is that there should be no button that sets these values (i.e.,
no button to cause a postback). The problem I'm having is that I need a
number of validations to be performed on the data entry, but I don't know
how to do this without having the user control/page posted back to the
server. ...

Hi guys,
I am trying to read from a USB keyboard using vb.net and HID classes. the

and I am getting valid handles. however, everytime I use the readfile

Hello:
There are a series of textboxes (x.text, y.text, z.text etc.) in which user input is expected.
As:
dtmX=CDate(x.text)
dtmY=CDate(y.text)
dtmZ=CDate(z.text)
where x, y, and z.text must be in hh:mm format.

I have a barcode scanner which uses a "keyboard wedge" program so that the
data it scans comes through as if it was typed on a keyboard. I am trying
to have the data in the barcode be displayed in a text box. I know that
there are certain control characters embedded in the data that I want to
display substitutions for in the text box, for instance I want to replace
ASCII character 04 with the string "<EOT>". I have tried doing a simple...

Hi all you hardcore coders and everyone else.
I'm a beginner programmer, so forgive me if this is a stupid question.
I'd like to be able to check if the user has pressed a key since I
flushed the keyboard buffer. But the only thing I can find is a function
kbhit(), which I believe is a Borland only component and not really a
part of ANSI C. kbhit() is not supported in any of my standard #include
files.
getch() stops execution and...

I created a user control that handles certain keystrokes, e.g. Ctrl-C for
cut, Ctrl-V for paste, plus other more specialized keystrokes. I want to list
these in the menubar like any other menu items. Once I assign a Shortcut Key
to the menu item, that menu sees the event before the control, as one would
expect. The question is, then, inside the menu item handler what code do I
need to pass on the keystroke to a control? This is slightly...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...

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...
