Hello,

How can I read HID (hardware id) of PC component, like hard disk hid,
mainboard hid, processor etc. ?

Please help.

Thanks in advance
Johns

You need to get familiar with WMI to get that type of information.

Here is a good starting point from which you can wander around to get
what you want:

I recommend you stop using HID to mean hardware ID. I'm willing to bet a
good chunk of us looked at the subject and thought "Human Interface Device,"
i.e., some form of (probably USB-based) input, as that is the major use of
the abbreviation these days. (You'll get better responses if you don't
confuse the responders, y'know?)

Different classes of hardware have different methods of accessing this info.
You will need to look into specific API calls, or research WMI.

And I seconds the comment about using the incorrect acronym, a HID is
something entirely different.

Hi Duke and others, thanks for the answer.

I have tried WMI for the first time. The following code comes from
http://msdn.microsoft.com/en-us/library/aa394585%28VS.85%29.aspx

Sub t1()
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")
Set colSMBIOS = objWMIService.ExecQuery _
("Select * from Win32_SystemEnclosure")
For Each objSMBIOS In colSMBIOS
Debug.Print "Part Number: " & objSMBIOS.PartNumber
Debug.Print "Serial Number: " & objSMBIOS.SerialNumber
Debug.Print "Asset Tag: " & objSMBIOS.SMBIOSAssetTag
Next
End Sub

It seems that the code does not give the ouput accurately. Like this :

Part Number:
Serial Number: Chassis Serial Number
Asset Tag: Asset -1234567890

I only need to get hard disk,processor and mainboard unique id. Sorry
for incorrect use of the word HID.
Could anyone give me the best way ?

John S
