[RESOLVED] [2005]hard disk serial number

Hi,

I am using VB2005

How can I detect hard disk serial number without API

Thanks in advance

Have a look through System.Management.

You can use WMI through managed code, e.g.

vb.net Code:

''' <summary>
''' Gets a value that identifies this system for licensing purposes.
''' </summary>
''' <returns>
''' An string containing a relatively unique value that identifies the system as being linked to a license key.
''' </returns>
Private Shared Function GetSystemID() As String
    Dim driveMedium As DiskDrivePhysicalMedia
    Dim drive As DiskDrive
    Dim medium As PhysicalMedia
    Dim interfaceType As String
    Dim serialNumber As String
    Dim systemID As Integer = 0
 
    Using driveMedia As New ManagementClass("Win32_DiskDrivePhysicalMedia")
        For Each mo As ManagementObject In driveMedia.GetInstances()
            driveMedium = New DiskDrivePhysicalMedia(mo)
            drive = New DiskDrive(driveMedium.Dependent)
            medium = New PhysicalMedia(driveMedium.Antecedent)
 
            interfaceType = drive.InterfaceType
            serialNumber = medium.SerialNumber
 
            drive.Dispose()
            medium.Dispose()
            mo.Dispose()
 
            'Look for an IDE or SCSI drive with a serial number.
            If (interfaceType = "IDE" OrElse interfaceType = "SCSI") AndAlso _
               serialNumber <> Nothing Then
                'Hash the serial number of the first hard drive as the system ID.
                systemID = serialNumber.GetHashCode()
                Exit For
            End If
        Next mo
    End Using
 
    If systemID = 0 Then
        'Use the computer name as a fail safe.
        systemID = My.Computer.Name.GetHashCode()
    End If
 
    Return systemID.ToString()
End Function

Note that the DiskDrivePhysicalMedia, DiskDrive and PhysicalMedia classes are all .NET classes generated by the MgmtClassGen.exe utility that comes with the .NET Framework SDK. They each correspond to an unmanaged WMI class. You can find information on using the utitlity in the MSDN library, then just import the generated class files into your project.

Hi,

I added References to System. Management and Imports System.Management
Do I have to add anything else ?
Because I get an errors

Hi,

I found at: http://www.vbforums.com/showpost.php...50&postcount=3
Little example that posted by jmcilhinney and it's working ok.

My question is if it's doing the same like the code above?

If you need to ask that question then you haven't really looked at the code, or read what was posted, very carefully. In both posts I use the same class names and the same variable names, and I mentioned using the same utility to generate the .NET wrappers for the WMI classes in both. This thread's code has just been changed a little because it's in a different app and it's been updated slightly for VB 2005. Other than that they are almost identical.

Hi,

First of all thanks jmcilhinney

The code that you post in this thread I get errors. And I wrote it.
Because of the errors I search for other code.

Thanks again

What errors did you get? Are they a secret? If we don't know what they are we can't help you fix them.

Hi,

Look at the attached picture.

c# Code:

using System;
using System.Collections;
using System.Management;
 
namespace HardDriveSample1
{
    class HardDrive
    {
        private string model = null;
        private string type = null;
        private string serialNo = null;
 
        public string Model
        {
            get {return model;}
            set {model = value;}
        }
 
        public string Type
        {
            get {return type;}
            set {type = value;}
        }
 
        public string SerialNo
        {
            get {return serialNo;}
            set {serialNo = value;}
        }
    }
 
    class TestProgram
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main(string[] args)
        {
            ArrayList hdCollection = new ArrayList();
 
            ManagementObjectSearcher searcher = new
                ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
 
            foreach(ManagementObject wmi_HD in searcher.Get())
            {
                HardDrive hd = new HardDrive();
                hd.Model    = wmi_HD["Model"].ToString();
                hd.Type     = wmi_HD["InterfaceType"].ToString();
 
                hdCollection.Add(hd);
            }
 
            searcher = new
                ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
 
            int i = 0;
            foreach(ManagementObject wmi_HD in searcher.Get())
            {
                // get the hard drive from collection
                // using index
                HardDrive hd = (HardDrive)hdCollection[i];
 
                // get the hardware serial no.
                if (wmi_HD["SerialNumber"] == null)
                    hd.SerialNo = "None";
                else
                    hd.SerialNo = wmi_HD["SerialNumber"].ToString();
 
                ++i;
            }
 
            // Display available hard drives
            foreach(HardDrive hd in hdCollection)
            {
                Console.WriteLine("Model\t\t: " + hd.Model);
                Console.WriteLine("Type\t\t: " + hd.Type);
                Console.WriteLine("Serial No.\t: " + hd.SerialNo);
                Console.WriteLine();
            }
 
            // Pause application
            Console.WriteLine("Press [Enter] to exit...");
            Console.ReadLine();
        }
    }
}

It's weird. I found the above c# code that works but when I converted it to vb.net it came up with some errors. Mainly it said that System.Management contained no public members. I do not know the solution.

yulyos, if you hover the mouse above those errors, the IDE will give you correction suggestions. You probably havent imported the correct namespaces.

Actually Atheist, I pasted the same code and the errors do not show any suggestions. I also tried searching for the underlined words in the object browser and it came up empty.

Hi yulyos,

Here's a way to find the serialnumber of your Harddisk.
Use a multiline Textbox to see your HDDserialnumber.

Code:

---

Imports System
Imports System.Collections
Imports System.Management
Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim hdCollection As New ArrayList()
        Dim searcher As New ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive")
        Dim wmi_HD As New ManagementObject()

        For Each wmi_HD In searcher.Get

            Dim hd As New HardDrive()

            hd.Model = wmi_HD("Model").ToString()
            hd.Type = wmi_HD("InterfaceType").ToString()
            hdCollection.Add(hd)
        Next

        Dim searcher1 As New ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia")


        Dim i As Integer = 0
        For Each wmi_HD In searcher1.Get()

            '// get the hard drive from collection
            '// using index

            Dim hd As HardDrive
            hd = hdCollection(i)


            '// get the hardware serial no.
            If wmi_HD("SerialNumber") = "" Then
                hd.serialNo = "None"
            Else
                hd.serialNo = wmi_HD("SerialNumber").ToString()
                i += 1
            End If
        Next

        Dim hd1 As HardDrive
        Dim ii As Integer = 0

        For Each hd1 In hdCollection
            ii += 1
            TextBox1.Text = TextBox1.Text + "Disco #: " + ii.ToString + Chr(13) + Chr(10)
            TextBox1.Text = TextBox1.Text + "Model: " + hd1.Model + Chr(13) + Chr(10)
            TextBox1.Text = TextBox1.Text + "Tipo: " + hd1.Type + Chr(13) + Chr(10)
            TextBox1.Text = TextBox1.Text + "Serial No: " + hd1.serialNo + Chr(13) + Chr(10) + Chr(13) + Chr(10)
        Next

    End Sub

End Class

Public Class HardDrive
    Private dsk_model As String
    Private dsk_type As String
    Private dsk_serialNo As String

    Public Property Model() As String

        Get
            Return dsk_model
        End Get
        Set(ByVal value As String)
            dsk_model = value
        End Set
    End Property

    Public Property Type() As String

        Get
            Return dsk_type
        End Get
        Set(ByVal value As String)
            dsk_type = value
        End Set
    End Property

    Public Property serialNo() As String
        Get
            Return dsk_serialNo
        End Get
        Set(ByVal value As String)
            dsk_serialNo = value
        End Set
    End Property


End Class

Wkr,

It is my feeling that if you post code then people copy the code and ignore anything else you post. That's why I avoid posting code a lot of the time: because I want people to read my words, think about them and develop some understanding of what I'm trying to convey. It seems that this is another case of code copied and words ignored. No doubt the error messages say that those classes are not defined. In the very same post that you copied that code from I told you how to define those classes:

I provided essentially the same advice in that other post you found:

I have done this myself recently, and I found that the best way was to use the mgmtclassgen.exe utility to generate .NET classes that correspond to the WMI classes and then use code like this: ... The DiskDrivePhysicalMedia, DiskDrive and PhysicalMedia classes are the ones generated by the utility. Do a help search for the name and you'll find a topic that tells you how to use it.

If you're going to just copy and paste code without reading the explanation that goes with then you're only going to get half the story.

Hi,

This little code that posted by jmcilhinney doing all the work.

Code:

---

        Imports System.Management

        Dim physicalMedia As New Management.ManagementClass("Win32_PhysicalMedia")

        For Each physicalMedium As Management.ManagementObject In physicalMedia.GetInstances()
            MessageBox.Show("Serial Number: " & CStr(physicalMedium("SerialNumber")))
        Next physicalMedium

Thanks to everybody
