Hi, I'm a newbie to programming of any kind. I have posted this to other
groups in a hope to get a response from anyone.
Can any one tell me how to make my VB program read the Bios serial number
(or would HDD be better, or both?) and put that info into VB prog so the
program won't work on another computer. My program uses an MSAccess table.
Much appreciated if you can help!
Thanks

Is there any way of simply using the COM port from Visual Basic? All the
solutions I've found seem to require the use of Visual Studio whereas I only
have the the 'basic' version. I'm not after anything too complicated as all I
want to do is read a serial stream of data.
Thanks in advance

I wrote a program that communicate with SerialComm. In every 300
milliseconds, my program continuously send & receive data via the serial
port once the program starts.
My program is once in a while, the serial port seems corrupted because when
my data is sent, it doesn't go through the serial port, so as same to
receive process. In order to fix this, I have to close the port and reopen
the port again.
Why?!! Is there any way to fix...

Below is the code in Managed C++. It was originally written in C, and
posted somewhere around the Internet (I forgot where I copied this
code), and I changed it into Managed C++. This code returnes the
serial string like "WD-WC1234567" of the hard disk where C drive is
on.
Now, I would like to change this code into C#, but there are so many
API's, structures and macroes. I've searched the Internet for
equivalent C# code but I couldn't...

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...
