The following functions rely primarily on WMI implementations

Get the hard drive serial number

The code is as follows	Copy Code
Dim Cmicwmi as New System.Management.ManagementObjectSearcher ("SELECT * from Win32_DiskDrive") Dim Uint32 as UInt32 For each cmicwmiobj as ManagementObject in Cmicwmi.get Uint32 = cmicwmiobj ("signature") Next TextBox1.Text = uint32.tostring

　　

Get CPU Serial Number

The code is as follows	Copy Code
Dim Wmi as New System.Management.ManagementObjectSearcher ("SELECT * from Win32_Processor") Dim Uint32 as String For each wmiobj as ManagementObject in Wmi.get Uint32 = Wmiobj ("Processorid") Next TextBox1.Text = Uint32

Get total drive capacity

The code is as follows	Copy Code
Dim Wmi as New System.Management.ManagementObjectSearcher ("SELECT * from Win32_DiskDrive") Dim Uint64 as UInt64 For each wmiobj as ManagementObject in Wmi.get Uint64 = wmiobj ("size") Next TextBox1.Text = uint64.tostring
