Hi guys,

I'm trying to use the Open Hardware Monitor library to read some values about the hardware. I know that I could run directly OpenHardwareMonitor.exe and read from WMI but I want to use the library.

It is written in C# but I've read from >this topic I can use RegAsm to register the types in the registry so I could run the classes in the library as COM objects.

I've downloaded the source, changed COMVISIBLE property to TRUE and compiled the library with MSBuild.exe

I would convert this (or this) script to Autoit but after some lines of code I get an error: "Invalid pointer".

I don't understand why I get that error, I don't think it's cause RegAsm because it gives me a warning but then it does its job registering the types.

#RequireAdmin
$RegAsm_path = "C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm" ; CHECK YOUR VERSION!!!
$foo = Run($RegAsm_path & " /codebase /nologo OpenHardwareMonitorlib.dll", "", @SW_HIDE, 0x2 + 0x4)
$std = _Read_Std($foo)
MsgBox(0,$foo,$std)

$oMyError = ObjEvent("AutoIt.Error","MyErrFunc")

$cp = ObjCreate("OpenHardwareMonitor.Hardware.Computer")
If IsObj($cp) Then MsgBox(0,"OpenHardwareMonitor.Hardware.Computer","Object created")
$cp.Open() ; <--------------- ERROR

RunWait($RegAsm_path & " /nologo /unregister OpenHardwareMonitorlib.dll", "", @SW_HIDE)

Func MyErrFunc()
    $HexNumber=hex($oMyError.number,8)
    Msgbox(0,"","We intercepted a COM Error !" & @CRLF & _
        "Number is: " & $HexNumber & @CRLF & _
        "Windescription is: " & $oMyError.windescription & @CRLF & _
        "Source is: " & $oMyError.source & @CRLF & _
        "Description is: " & $oMyError.description & @CRLF & _
        "Script line is: " & $oMyError.scriptline)
    RunWait($RegAsm_path & " /nologo /unregister OpenHardwareMonitorlib.dll", "", @SW_HIDE)
    Exit
Endfunc

Func _Read_Std($handle)
    Local $s
    While 1
        $s &= StdoutRead($handle)
        If @error Then ExitLoop
        $s &= StderrRead($handle)
        If @error Then ExitLoop
    WEnd
    Return $s
EndFunc 

I'll attach the compiled dll but you need to check .NET Framework folder first.

Thank you at all.

nothing, nothing can happen... COM error handling function contains an "exit" statement and the script ends before executing everything after $cp.Open (that generates the COM error)

New issue :) thanks to this patch I could write a new version of OpenHardwareMonitorLib.dll, now I can run my script without errors, till I try to enumerate a collection: then Autoit crashes without errors.
It seems to be an Autoit managing-object related issue and not an external library issue, I'll attach the new version of the library.
Have you got any idea?

#RequireAdmin
$RegAsm_path = "C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm" ; CHECK YOUR VERSION!!!
$foo = Run($RegAsm_path & " /codebase /nologo OpenHardwareMonitorlib.dll", "", @SW_HIDE, 0x2 + 0x4)
Sleep(1000)

$oMyError = ObjEvent("AutoIt.Error", "MyErrFunc")

$cp = ObjCreate("OpenHardwareMonitor.Hardware.Computer")
If IsObj($cp) Then
    MsgBox(0, "OpenHardwareMonitor.Hardware.Computer", "Object created")
    $cp.Open()
    $cp.GPUEnabled = True
    $cp.CPUEnabled = True
    $a = $cp.Hardware
    MsgBox(0,"Var type",VarGetType($a))

    For $HWItem In $a ;---------> error
        MsgBox(0, 1, "hello")
    Next
Else
    MsgBox(16, "ERROR", "Object not created")
EndIf


RunWait($RegAsm_path & " /nologo /unregister OpenHardwareMonitorlib.dll", "", @SW_HIDE)

Func MyErrFunc()
    $HexNumber = Hex($oMyError.number, 8)
    MsgBox(0, "", "We intercepted a COM Error !" & @CRLF & _
            "Number is: " & $HexNumber & @CRLF & _
            "Windescription is: " & $oMyError.windescription & @CRLF & _
            "Source is: " & $oMyError.source & @CRLF & _
            "Description is: " & $oMyError.description & @CRLF & _
            "Script line is: " & $oMyError.scriptline)
    RunWait($RegAsm_path & " /nologo /unregister OpenHardwareMonitorlib.dll", "", @SW_HIDE)
    Exit
EndFunc   ;==>MyErrFunc

Func _Read_Std($handle)
    Local $s
    While 1
        $s &= StdoutRead($handle)
        If @error Then ExitLoop
        $s &= StderrRead($handle)
        If @error Then ExitLoop
    WEnd
    Return $s
EndFunc   ;==>_Read_Std

P.S: extract the dll in the same directory of the script and check your .NET Framework version  :bye:

EDIT:

I adjusted the code formatting

OpenHardwareMonitorLib.zip

We need more information to track down the error:

Which version of AutoIt?

What's the result of VarGetType($a)?

Do you get any messages from the COM error handler?

The history for the latest AutoIt beta version doesn't list fixes for COM problems so I fear installing the latest beta won't help.

If $a.count returns a value you could loop through the collection like an array. Maybe this works.

Count method is not exported by the library and the COM error handler reports a NULL pointer error if I try to do $a.Count.

This is what ILSpy shows about method and properties exported with Computer Class (on the left) and the source code of Hardware method (on the right):

"Business reading"? Ehm... what?

EDIT:

I tried something about c0000005: http://stackoverflow.com/a/17169463/3812399

But it doesn't really help until I will inspect $a to see if it is empty or something else.

Just a clarification, the library works without problems if I don't try to enumerate that collection, for example if you run this script it works:

#RequireAdmin
$RegAsm_path = "C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm" ; CHECK YOUR VERSION!!!
$foo = Run($RegAsm_path & " /codebase /nologo OpenHardwareMonitorlib.dll", "", @SW_HIDE, 0x2 + 0x4)
Sleep(1000)

$oMyError = ObjEvent("AutoIt.Error", "MyErrFunc")

$cp = ObjCreate("OpenHardwareMonitor.Hardware.Computer")
If IsObj($cp) Then
    MsgBox(0, "OpenHardwareMonitor.Hardware.Computer", "Object created")
    $cp.Open()
    $cp.GPUEnabled = True
    $cp.CPUEnabled = True
    $a = $cp.Hardware
    MsgBox(0,"Var type",VarGetType($a))
    FileWrite(@DesktopDir & "\log.txt", $cp.GetReport)

Else
    MsgBox(16, "ERROR", "Object not created")
EndIf


RunWait($RegAsm_path & " /nologo /unregister OpenHardwareMonitorlib.dll", "", @SW_HIDE)

Func MyErrFunc()
    $HexNumber = Hex($oMyError.number, 8)
    MsgBox(0, "", "We intercepted a COM Error !" & @CRLF & _
            "Number is: " & $HexNumber & @CRLF & _
            "Windescription is: " & $oMyError.windescription & @CRLF & _
            "Source is: " & $oMyError.source & @CRLF & _
            "Description is: " & $oMyError.description & @CRLF & _
            "Script line is: " & $oMyError.scriptline)
    RunWait($RegAsm_path & " /nologo /unregister OpenHardwareMonitorlib.dll", "", @SW_HIDE)
    Exit
EndFunc   ;==>MyErrFunc

Func _Read_Std($handle)
    Local $s
    While 1
        $s &= StdoutRead($handle)
        If @error Then ExitLoop
        $s &= StderrRead($handle)
        If @error Then ExitLoop
    WEnd
    Return $s
EndFunc   ;==>_Read_Std

But GetReport method returns a string, not an array as .Hardware method.

Is there any way to look into $a (other else than Count)?

      Good evening everyone
      I'm working on a little project of mines, and I was trying to use WMI Object.
      The question which I don't find an answer is: 
      Once I do the query with WMI Object, something like "SELECT * FROM Win32_LogonSession", instead of specify the field of the collection returned, ( i.e. $colItems.Caption ), can I loop though each property and each value of the property, writing so one row of code only?
      Hope my question was clear enough.
      Thanks in advance.

      Best Regards.

      I was Playing around With AutoIt this evening and wondered how hard it would be to get typeinfo like the COM Viewers do only using AutoIt
      Turns out it was pretty easy.
      A Few Notes:
      CAarray info is unfinished I didn't have any objects to test it on so I left it Limited.
      The Object must have IDispatch exposed (ITypeInfo is derivative)
      Its Just a proof of concept Run with it but don't carry scissors
      ITypeInfoCOM.au3
      ITypeInfoTest.au3

       Hello all"
      I have curious problem with com object implementation of Sapi 5.1.
      In some cases }Some Voice engines] the metods for retrieve the voice parameters fails with error :Member not exists:.
      But the Retrieved Voice object can speak the given text, so It exists and work.
      Example of this type of Engine can be this one: http://download.kobavision.be/KobaSpeech3/KobaSpeech 3 With Vocalizer Serena - English (Great Britain).exe (can work as demo)
      So my question is> Is there some way to workaround or solve this issue?
      What i tryed:
      1. Typical use of Sapi.spvoice object:
      $oMyError = ObjEvent("AutoIt.Error","MyErrFunc"); Install a custom error handler
       
        $spvoice = ObjCreate("sapi.spvoice")
      for $voice in $spvoice.getvoices()
        msgbox(0, "Voice", $voice.getdescription())
      next
      Func MyErrFunc()
      $HexNumber = hex($oMyError.number, 8)
      Msgbox(0,"","We intercepted a COM Error !" & @CRLF &"Number is: " & $HexNumber & @CRLF &"Windescription is: " & $oMyError.windescription)
      SetError(1)
      Endfunc

      2. Implement workaround based on Nvda Screen reader sapi5 Library at https://github.com/nvaccess/nvda/blob/master/source/synthDrivers/sapi5.py
      Thys code in Pascal should work, so i tryed to reproduce it in Autoit.
      Pascal code just as example:
                   SOTokens:=SpVoice.GetVoices('','');
                   for i:=0 to SOTokens.Count-1 do
                   try
                        SOToken:=SOTokens.Item(I); s:=SOToken.GetDescription(0);
      end
      In Autoit I tryed it like this:
      $oMyError = ObjEvent("AutoIt.Error","MyErrFunc"); Install a custom error handler
        $spvoice = ObjCreate("sapi.spvoice")
      for $i = 0 to $spvoice.getvoices.count-1
      $name = $spvoice.getvoices.item($i).getdescription
      msgbox(0,"Voice", $name)
      next
      Func MyErrFunc()
      $HexNumber = hex($oMyError.number, 8)
      Msgbox(0,"","We intercepted a COM Error !" & @CRLF &"Number is: " & $HexNumber & @CRLF &"Windescription is: " & $oMyError.windescription)
      SetError(1)
      Endfunc
      Both of this methods returning same Error ("Member not exists.").
      Thanks a lot for help.
