DllCall MS MDT 2012 Microsoft.BDD.Utility.dll

[Gregor1806]

Hi folks,

Please can someone help.  I found the following web article, which explains what I'm trying to do - except I want to do this natively within AutoIt code instead of using the VBS that the link provides: http://www.verboon.info/index.php/2012/12/exploring-the-functions-included-in-microsoft-bdd-utility-dll/

I've been trying to make this work, but so far unsuccessfully.  I just keep getting the @error code set to 1 and no results.  My attempts are here:

If @OSArch = "X86" Then
    $sDllName = @ScriptDir & "\x86Microsoft.BDD.Utility.dll"
ElseIf @OSArch = "X64" Then
    $sDllName = @ScriptDir & "\x64Microsoft.BDD.Utility.dll"
EndIf

;~ $oShell = ObjCreate("WScript.Shell")
;~ $sDllName = @ScriptDir & "\Microsoft.BDD.Utility.dll"
;~ $oShell.Run ("regsvr32.exe /s """ & $sDllName & """", 0, 1)
;~ $oBDDUtility = ObjCreate("Microsoft.BDD.Utility")

;~ $dll = DllOpen($sDllName)
;~ $sIsUEFI = DllCall($dll, "int", "IsUEFI")
$sIsUEFI = DllCall($sDllName, "int", "IsUEFI")
;~ $sSupports64Bit = DllCall($dll, "int", "Supports64Bit")
MsgBox(0, "", @error)
If IsArray($sIsUEFI) Then MsgBox(0, "", "UEFI: " & $sIsUEFI[0])
;~ MsgBox(0, "", "Supports64Bit: " & $sSupports64Bit)
;~ DllClose($dll)
Exit

;~ $bIsUEFI = 0
;~ $bIsUEFI = $oBDDUtility.IsUEFI

;~ $bIsAdmin = 0
;~ $bIsAdmin = $oBDDUtility.IsAdmin

;~ $bIsHyperVirsorRunning = 0
;~ $bIsHyperVirsorRunning = $oBDDUtility.IsHypervisorRunning

;~ $bSupportsNX = 0
;~ $bSupportsNX  = $oBDDUtility.SupportsNX

;~ $bSupportsVT = 0
;~ $bSupportsVT = $oBDDUtility.SupportsVT

;~ $bSupports64Bit = 0
;~ $bSupports64Bit = $oBDDUtility.Supports64Bit

;~ $bIs64Bit = 0
;~ $bIs64Bit = $oBDDUtility.Is64Bit

;~ ConsoleWrite("UEFI: " & $bIsUEFI & @CRLF)
;~ ConsoleWrite("Is Admin: " & $bIsAdmin & @CRLF)
;~ ConsoleWrite("Is HyperVisor Running: " & $bIsHyperVirsorRunning & @CRLF)
;~ ConsoleWrite("Supports NX: " & $bSupportsNX & @CRLF)
;~ ConsoleWrite("Supports VT: " & $bSupportsVT & @CRLF)
;~ ConsoleWrite("Supports 64 Bit: " & $bSupports64Bit & @CRLF)
;~ ConsoleWrite("Is 64 Bit: " & $bIs64Bit & @CRLF)

Can anyone help me understand where I'm going wrong with this?  I did try searching the forums for answers first, but couldn't find anything related to this particular dll.

Basically, I want to use this MDT dll to determine if the machine is running in UEFI or BIOS mode.  Any help or advice is greatfully received!

Many thanks,

G.

Have you registered the dll?

OK, I played around with it a bit more and realised that my issues were related to OSArch.  I've tested the snippet below and it all seems to work - albeit without using DllCall - as I couldn't get that to work.  If anyone has time to explain how to achieve the same result as the below script using the native DllCall AutoIt command, I'd love to see how it is done (from a learning perspective) - but otherwise the following code is working fine for me (have tested it on W8 x64 and W7 x86).

#RequireAdmin
If @OSArch = "X86" Then
    #Region ;**** Directives created by AutoIt3Wrapper_GUI ****
    #AutoIt3Wrapper_UseX64=n
    #EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
    $sDllName = @ScriptDir & "\x86Microsoft.BDD.Utility.dll"
ElseIf @OSArch = "X64" Then
    #Region ;**** Directives created by AutoIt3Wrapper_GUI ****
    #AutoIt3Wrapper_UseX64=y
    #EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
    $sDllName = @ScriptDir & "\x64Microsoft.BDD.Utility.dll"
EndIf

RunWait('regsvr32.exe /s "' & $sDllName & '"', "", @SW_HIDE)
$oBDDUtility = ObjCreate("Microsoft.BDD.Utility")

If @error Then
    MsgBox(0, "@Error", @error)
    Exit
EndIf

If IsObj($oBDDUtility) Then
    Local $bIsUEFI, $bIsAdmin, $bIsHyperVisorRunning, $bSupportsNX, $bSupportsVT, $bSupports64Bit, $bIs64Bit

    $bIsUEFI = $oBDDUtility.IsUEFI
    $bIsAdmin = $oBDDUtility.IsAdmin
    $bIsHyperVisorRunning = $oBDDUtility.IsHyperVisorRunning
    $bSupportsNX  = $oBDDUtility.SupportsNX
    $bSupportsVT = $oBDDUtility.SupportsVT
    $bSupports64Bit = $oBDDUtility.Supports64Bit
    $bIs64Bit = $oBDDUtility.Is64Bit

    MsgBox(0, "Results", "UEFI: " & $bIsUEFI & @CRLF & _
     "Is Admin: " & $bIsAdmin & @CRLF & _
     "Is HyperVisor Running: " & $bIsHyperVisorRunning & @CRLF & _
     "Supports NX: " & $bSupportsNX & @CRLF & _
     "Supports VT: " & $bSupportsVT & @CRLF & _
     "Supports 64 Bit: " & $bSupports64Bit & @CRLF & _
     "Is 64 Bit: " & $bIs64Bit)
EndIf

RunWait('regsvr32.exe /s /u "' & $sDllName & '"', "", @SW_HIDE)

Thanks,

I don't think you have to register and unregister your dll each time.

Just registering it once should do.
