How can my WinForms app get the users MachineID or ProcessorID?

Question

I'm looking for a way to retrieve the user's MachineID or ProcessorID using a VB.net WinForms app? Any thoughts?

Answer 1

You can access that information using WMI.

string s = "SELECT SerialNumber FROM WIN32_BaseBoard";
System.Management.ManagementObjectSearcher oWMI = new
System.Management.ManagementObjectSearcher(s);
System.Management.ManagementObjectCollection oSerialNumbers = oWMI.Get();

foreach (System.Management.ManagementObject mo in oSerialNumbers)
{
Console.WriteLine("Serial Number: " +
mo.Properties["SerialNumber"].Value.ToString());
}

Another option is to get the MAC address of one of the network cards in your system. This is a unique number The following routine gets a mac address of the first network card, and then appends the bytes in the address into a unique ulong (sorry for the C# instead of VB.NET):

using System.Net.NetworkInformation;
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
if (nics.Length != 0)
{
    byte[] addressBytes = nics[0].GetPhysicalAddress().GetAddressBytes();
    if (addressBytes.Length > 6)
        throw new ApplicationException("Unexpected length for MAC address");

    ulong address = 0;
    foreach (byte b in addressBytes)
    {
        address
