C ++ hardware information to obtain the hard disk serial number and the hard disk serial number

This section describes how to obtain the serial number of a hard disk, not the serial number of a hard disk partition. The core is throughDeviceIoControlInterface to obtain the version and data information of the hard disk.

Simple.

1. Obtain the disk serial number, volume label, and file system type.
The disk serial number is re-generated after each floppy disk or hard disk formatting and is not repeated. Many programmers use this encryption. You can also modify this function to obtain the disk volume label and file system type information.
Statement:
Private Declare Function GetVolumeInformation Lib "kernel32.dll" Alias "volumes" (ByVal lpRootPathName As String, ByVal encoded As String, ByVal nVolumeNameSize As Integer, stored As Long, stored As Long, lpFileSystemFlags As Long, byVal lpFileSystemNameBuffer As String, ByVal nFileSystemNameSize As Long) As Long
Code:
Function GetSerialNumber (sRoot As String) As Long
Dim lSerialNum As Long
Dim R As Long
Dim sTemp1 As String, sTemp2 As String
StrLabel = String $ (255, Chr $(0 ))
Note: disk volume label
StrType = String $ (255, Chr $(0 ))
Note: The file system type is generally FAT.
R = GetVolumeInformation (sRoot, strLabel, Len (strLabel), lSerialNum, 0, 0, strType, Len (strType ))
GetSerialNumber = lSerialNum
Note: Mark the disk volume in strLabel.
Note: In strType, It is the file system type.
End Function
Usage:
If the drive does not exist, the function returns 0. If it is a non-root directory, 0 is returned:
LSerial = GetSerialNumber ("c :\")
2. You only need to paste the following code into the VB project and save it as a class. I have tested all the code and used it in many development projects.

How can I obtain the hardware information of a visitor's machine, such as the hard disk serial number and cpu id?

You can download a drive life that can detect the hardware information of the visitor's machine.
