Hi, All and @behnam_tr

Today a user of my app reported the error:

in the getting win hardware ID sub https://www.b4x.com/android/forum/t...ets-test-windows-os-hardware-device_id.165018 under Windows11 24H2.

The WMI command-line (WMIC) utility provides a command-line interface for Windows Management Instrumentation (WMI).

@behnam_tr, is it possible to debug the lib v.2.7 under this Win version for you ?

@Peter Simpson, did your customers use the jUUID lib in your apps under Win11 already?

behnam_tr · Jan 12, 2025

Hello
I will test and post the results here.

Thanks !
The error log mentioned only 3 functions, not all:

at b4j/ir.padina.jUUID.Get_MachineID(Unknown Source)
at b4j/ir.padina.jUUID.Get_HddID2(Unknown Source)
at b4j/ir.padina.jUUID.Get_BiosVersion(Unknown Source)

Daestrum · Jan 12, 2025

when I ran your test (the other thread mentioned) I was using 24H2

peacemaker · Jan 12, 2025

ooops, interesting...

So, seems the jUUID lib depends on the system "wmic" utility that ... may be absent.
I have found now it here:

"C:\Windows\System32\wbem\WMIC.exe"

Daestrum · Jan 12, 2025

I do get a warning though if I use from command prompt

>wmic /?

WMIC is deprecated.

[global switches] <command>

The following global switches are available:
/NAMESPACE Path for the namespace the alias operate against.
/ROLE Path for the role containing the alias definitions.
/NODE Servers the alias will operate against.
/IMPLEVEL Client impersonation level.

check this :

Add or Remove WMIC command Feature in Windows 11

This tutorial will show you how to add or remove the WMIC command as an optional feature for all users in Windows 11. The WMI command-line (WMIC) utility provides a command-line interface for Windows Management Instrumentation (WMI). WMIC is compatible with existing shells and utility commands...

MS is super...
Please, make in the lib try\catch on each function, to make sure that "null" is returned also if WMIC trouble would be on the user machine.
Or more correct is to trap on the app side ?

I tested it on version 24 and the problem was solved by enabling Wmic.
Yes, I will update soon and add a try/catch.
And also the ability to check wmic feature is enable or not.

I already added try\catch so:

B4X:

Sub Get_DeviceID As String
    Dim sb As StringBuilder
    sb.Initialize
    Dim sr As String
    Try   
        Dim sr As String = pdd.Get_MotherboardSN
        If sr <> Null And Not(sr.Contains("O.E.M")) Then sb.Append(sr)
    Catch
    End Try
    Try
        sr = pdd.Get_CPUID
        If sr <> Null Then sb.Append(sr)
    Catch
    End Try
    Try
        sr = pdd.Get_MachineID
        If sr <> Null Then sb.Append(sr)
    Catch
    End Try
    Try
        sr = pdd.Get_HddID1
        If sr <> Null Then sb.Append(sr)
    Catch
    End Try
    Try
        sr = pdd.Get_HddID2
        If sr <> Null Then sb.Append(sr)
    Catch
    End Try
    Try
        sr = pdd.Get_MacId
        If sr <> Null Then sb.Append(sr)
    Catch
    End Try
    Try
        sr = pdd.Get_BiosVersion
        If sr <> Null Then sb.Append(sr)
    Catch
    End Try
    Try
        sr = pdd.Get_CPUName
        If sr <> Null Then sb.Append(sr)
    Catch
    End Try
    Try
        sr = pdd.Get_GpuID
        If sr <> Null Then sb.Append(sr)
    Catch
    End Try
    Try
        sr = pdd.Get_MotherboardSN2
        If sr <> Null Then sb.Append(sr)
    Catch
    End Try
    Try
        sr = pdd.Get_HWID1
        If sr <> Null Then sb.Append(sr)
    Catch
    End Try
    
    sr = sb.ToString
    
    If sr.Trim.Length < 8 Then
        sr = sr & GetEnvironmentVariable("computername","") & GetSystemProperty("user.name","")
    End If
    sr = sr.Replace(" ", "").Replace("\", "").Replace("/", "").Replace(":", "")
    sr = Main.appname & "_" & sr
    If sr.Length > 48 Then
        sr = sr.SubString2(0, 48)
    End If
    
    Return sr.ToLowerCase
End Sub

App on those user machine (with initial error) was started OK and returned "defaultstringbfebfbff000806c1104595......".
Some "defaultstring"

Which method returns this value?

behnam_tr · Jan 12, 2025

lib updated
try with v2.8

No exact idea - you see that some parts may be passed if Null. I may guess that "defaultstring" was from first .Get_MotherboardSN
