Vb6 Get Serial Number

Posted : admin On 5/29/2019
Hi folks,
I have to write a Visual Basic 6.0 Program and need to uniquely identify a
computer in a network and the user mustn't be able to change that id while my
program is running. So the Volume Serial Number of the HDD isn't a possibility,
because you can set the Volume SN whatever you want and therefore it's not
unique in a Network. I heard that there's a manufacturer's Serial Number on the
HDD that can't be changed and that is unique (worldwide?). How can I get that SN
with VB6? Or do you have any other ideas? Like a BIOS SN?
Thanks a lot in advance,
Michael
PS: Answer in German is ok.

Vb6 Get Serial Number

This topic describes how to use My.Computer.Ports to show the available serial ports of the computer in Visual Basic.

To allow a user to select which port to use, the names of the serial ports are placed in a ListBox control.

Example

Vb6

Get Serial Number

This example loops over all the strings that the My.Computer.Ports.SerialPortNames property returns. These strings are the names of the available serial ports on the computer.

Typically, a user selects which serial port the application should use from the list of available ports. In this example, the serial port names are stored in a ListBox control. For more information, see ListBox Control.

This code example is also available as an IntelliSense code snippet. In the code snippet picker, it is located in Connectivity and Networking. For more information, see Code Snippets.

Compiling the Code

Vb6 Get Cpu Serial Number

This example requires:

Serial

  • A project reference to System.Windows.Forms.dll.

  • Access to the members of the System.Windows.Forms namespace. Disable protexis licensing v2 in windows services. Add an Imports statement if you are not fully qualifying member names in your code. For more information, see Imports Statement (.NET Namespace and Type).

  • That your form have a ListBox control named ListBox1.

Robust Programming

You do not have to use the ListBox control to display the available serial port names. Instead, you can use a ComboBox or other control. If the application does not need a response from the user, you can use a TextBox control to display the information.

Note

The port names returned by My.Computer.Ports.SerialPortNames may be incorrect when run on Windows 98. To prevent application errors, use exception handling, such as the Try..Catch..Finally statement or the Using statement, when using the port names to open ports.
