Using .NET libary with AutoIt, possible?

LarsJ · March 7, 2017

If I call CLRCreateInstance in this way it leads to an immediate crash (0xC0000005, STATUS_ACCESS_VIOLATION):

Local $aRet = DllCall( "MSCorEE.DLL", "long", "CLRCreateInstance", "struct*", $tCLSID_CLRMetaHost, _
                       "struct*", $tIID_ICLRMetaHost, "ptr*", 0 )

A couple of weeks ago I did a few tests with CLR.ahk from our AutoHotkey friends. They are using the function CorBindToRuntimeEx also implemented in MSCorEE.DLL. This function works in AutoIt in this way:

Local $aRet = DllCall( "MSCorEE.dll", "long", "CorBindToRuntimeEx", "wstr", $sVersion, "ptr", NULL, "dword", 0, _
                       "struct*", $tCLSID_CorRuntimeHost, "struct*", $tIID_ICorRuntimeHost, "ptr*", 0 )

I don't know why CLRCreateInstance leads to a crash. It could be interesting to see if CLRCreateInstance is working in AutoHotkey.

A quick way to get around the problem and be able to move on is to call CLRCreateInstance through some C++ code in a DLL file. Whether you can get a pointer in this way which can be used in AutoIt, you simply have to test.

Local $aRet = DllCall("MSCorEE.DLL", "long", "CLRCreateInstance", "struct*", $tCLSID_CLRMetaHost, _
        "struct*", $tIID_ICLRMetaHost, "ptr*", 0)

If $aRet[0] = $S_OK Then
    Local $pClrHost = $aRet[3]
    ConsoleWrite("$pClrHost: " & $pClrHost & @CRLF)
EndIf
Func _WinAPI_CLSIDFromString($sGUID)
    $tGUID = DllStructCreate('ulong Data1;ushort Data2;ushort Data3;byte Data4[8]')
    $iRet = DllCall('ole32.dll', 'uint', 'CLSIDFromString', 'wstr', $sGUID, 'ptr', DllStructGetPtr($tGUID))

Danyfirex, Excellent. Your code also works for me.

My code was a little too short. I had only:

$tCLSID_CLRMetaHost = "{9280188D-0E8E-4867-B30C-7FA83884E8DE}"
$tIID_ICLRMetaHost = "{D332DB9E-B9B3-4125-8207-A14884F53216}"

ptrex, Now you have the pointer for ICLRMetaHost and you should be able to create the object.

And it's this C++ code in the link by junkew you are trying to translate into AutoIt?

HI Guys,

Good news ! thanks for all so far...

Nevertheless I am not a C++ code reader, but I will see how far we get... more eyes can help of course.

This is really great news ... I will test it later today...

If all works fine it opens a totally new world for the community ...

Thanks a lot for the efforts so far ...

Ps : I propose to move this post to the Example section.

Or even create a new section in the forum :yawn:

junkew · March 12, 2017

nice work and it rocks here also ;-)

Hard time to understand how to deal in AutoIt with all this pointer logic which is to me at least more difficult then it is in c++ or c# itself

Any reference / guide on this DLL thing from within AutoIt? Tried to get just a simple GetVersionString to work without a result (0,0 is printed). offcourse reading manual/help file on all DLL* functions

;~  HRESULT GetVersionString(
;~     [out, size_is(*pcchBuffer)] LPWSTR pwzBuffer,
;~     [in, out]  DWORD *pcchBuffer);
    ; Assign some space to get data back
    Local $mySTRUCT = DllStructCreate("wchar[16] pwzBuffer; dword pcchBuffer")
    dllstructsetdata($myStruct,"pcchBuffer",16) ;~ probably 32 should be given
    $oRunInfo.GetVersionString(dllstructgetptr($myStruct,"pwzBuffer"), dllstructgetptr($myStruct,"pcchBuffer"))
    ConsoleWrite(">Version: " & dllstructgetdata($myStruct,"pwzBuffer") & dllstructgetdata($myStruct,"pcchBuffer") & @CRLF)

Hi Danyfirex,

Tested all of this as well and runs like a charm and fast too .... you really rock ! :graduated:

added some cleanup code : (stop and release methods)

Local $iRet = 0
        $oRuntimeHost.Start()
        $oRuntimeHost.ExecuteInDefaultAppDomain(@ScriptDir & "\C#Library.dll", "ClassLibraryDemo.ClassDemo", "NetMsgBox", "AutoIt Rocks!!! " & @CRLF & "Danyfirex does too lol!!!", $iRet)
        ConsoleWrite(">Ret: " & $iRet & @CRLF)

    EndIf
    $oClrHost.Release()
    $oRunInfo.Release()
    $oRuntimeHost.Stop()
    $tRuntimeHost.Release()
EndIf

Since you have got your head wrapped around all of the the .NET interfacing. I was wondering how we could get access to the run the .NET Class Libraries inline.... without having to compile a C# library and accessing it through CLRHost Interface.

Like this : https://support.smartbear.com/testcomplete/docs/testing-with/advanced/using-external-functions/calling-from-dotnet-assemblies.html

Dim str, i

  ' Calling a class instance constructor
  Set str = dotNET.System.String.zctor_8(&H41, 3)
  Log.Message str.OleValue ' Using the OleValue property

  ' Calling a static method
  Set str = dotNET.System.String.Copy("Hello, world!")
  ' Calling a class instance (non-static) method
  i = str.IndexOf("w")
  Log.Message i

never new I could do a shorthand on structs with the dot syntax but cannot find in help file how this should behave

Example 1 on working/not working

;~ Why does this work
Local $tSize = DllStructCreate("dword data2; dword Data")
    $tSize.Data = 0
;~ Why does this fail: Variable must be of type "Object".
Local $tSize = DllStructCreate("wchar[16] data2; dword Data")
    $tSize.Data = 0

Example 2 why not working if in the structure is a member of wchar before my dword pcchBuffer/length value

;~ does not work
;~ Local $mySTRUCT = DllStructCreate("wchar[16] pwzBuffer;dword pcchBuffer")

;~ does work
Local $mySTRUCT = DllStructCreate("dword pwzBuffer;dword pcchBuffer")

;~  $oRunInfo.GetVersionString(null, dllstructgetptr($myStruct,2))
    $oRunInfo.GetVersionString(null, dllstructgetptr($myStruct,"pcchBuffer"))

    ConsoleWrite(">Required Size: " & dllstructgetdata($myStruct,2) & @CRLF)
    ConsoleWrite(">Required Size: " & dllstructgetdata($myStruct,"pcchBuffer") & @CRLF)

I understand @danyfirex code is cleaner. For me its more about learning how to translate this stuff in AutoIt (C/C3/C++ is so much easier) and understanding the details on these definitions in AutoIt

@ptrex I really don't understand what you mean :S. (I'll read the page you're talking about as soon I can maybe I'll get your point) or maybe you can get a better C++ example about what you mean.

thanks about cleaning code. I'm no sure if .Release is needed becase I think objCreateInterface do it by itself. I think. ( I'll check this later too) lol

@junkew

Example 1 Answer.

First does not works because allocated size should be after dataname

Wrong:

Local $tSize = DllStructCreate("wchar[16] data2; dword Data")

Because allocated size should be after dataname like:

Correct:

Local $tSize = DllStructCreate("wchar data2[16]; dword Data")

Example 2 Answer.

Answered with Example 1. It should be:

Local $mySTRUCT = DllStructCreate("wchar pwzBuffer[16];dword pcchBuffer")

Local $mySTRUCT = DllStructCreate("dword pwzBuffer;dword pcchBuffer")

and this work because you declare the structure correctly but when you try to use probably you'll get an app crash because method is expecting a pointer to an allocated string.

Just use

"GetVersionString hresult(wstr;dword*);"

And then

Local $sVer
$oRunInfo.GetVersionString($sVer, 65536)
ConsoleWrite($sVer & @CRLF)

Also dich the use of structs for guids when there you have "clsid" type available

"GetInterface hresult(clsid;clsid;ptr*);"

Local $pRuntimeHost
$oRunInfo.GetInterface($sCLSID_CLRRuntimeHost, $sIID_ICLRRuntimeHost, $pRuntimeHost)

Btw, it would be better to enumerate available runtimes and choose from there.

Good job Danyfirex. :kiss:

Danyfirex · March 12, 2017

@trancexx thank you lady. You're right. I really know all those types of ObjetCreateItnerface But I'm too lazy to set all correct ones (it does not mean that ptr was wrong) but I dont want to go so deep into interfaces documentations. For that I use most of the times ptr type (Also I love working with ptrs and structs...)

Kisses for you too (here where our romance starts...)

Saludos

According to the description :

https://msdn.microsoft.com/en-us/library/dd233125(v=vs.110).aspx

ICLRRuntimeInfo::LoadLibrary Method
Loads a .NET Framework library from the common language runtime (CLR) represented by an ICLRRuntimeInfo interface.

It's should be possible to .NET Framework library (not a custom build library)

like for example : System.Windows.Forms or System.String or any other native .net class libraries ?

I have searched the net but did not find any examples though...

junkew · March 12, 2017

my logic would be (implicitly assemblies will be loaded with the load function)

CurrentDomain.CreateInstanceFrom(“mscorlib.dll”, “system.string")

or with

gettype("system.string")

found by reading around on ironpython and dynamic language runtime (on top of clr)

edit: some other references to go thru

Type.GetType(“System.Int32”) can return type System.Int32 without mentioning mscorlib.dll.
CreateInstanceAndUnwrap method
https://msdn.microsoft.com/en-us/library/3c4f1xde(v=vs.113).aspx
Current domain (deprecated in version 4??)
https://msdn.microsoft.com/en-us/library/ms164326(v=vs.110).aspx
AppDomains
When the CLR COM server initializes, it creates an AppDomain. An AppDomain is a logical container for a set of assemblies. The first AppDomain created when the CLR is initialized is called the default AppDomain; this AppDomain is destroyed only when the Windows process terminates.
In addition to the default AppDomain, a host using either unmanaged COM interface methods or managed type methods can instruct the CLR to create additional AppDomains. The whole purpose of an AppDomain is to provide isolation. Here are the specific features offered by an AppDomain:

ICorRuntimeHost::GetDefaultDomain
HRESULT GetDefaultDomain (  
    [out] IUnknown** pAppDomain  
);

fully qualified names (weird on a list there is a ' in the type)

Hi All,

To make this solution more attractive / interesting there are 2 steps to investigate how to :

1. Access to the native .Net Class libraries (if possible not to have the DLL to loads first)

2. Run C# code inline .... using the inline compilation of the IL code.

Then there is no need to do pre-compilation to .Net DLL.

3. Optionally is to be able to compile the inline C# code to a DLL / EXE.

I will try to find out some articles where this is explained... next is that we need some to translate this to au3 code.

@junkew

The "CreateInstanceAndUnwrap Method" is a beta release an can be subject to changes as is mentioned in the article.

The approach I found to be used would be :

Retrieve default domain by ICorRuntimeHost::CreateDomain/GetDefaultDomain, and after use it to instantiate class instance - e.g. AppDomain.CreateInstanceFrom.

1. ICorRuntimeHost::CreateDomain Method

2. ICorRuntimeHost::GetDefaultDomain Method

3. AppDomain.CreateInstanceFrom Method

Hopefully DanyFirex can give us a hand to convert this in au3 code ?

junkew · March 13, 2017

Although its C++ it shows you can directly instantiate a system.int32 from unmanaged code

maybe in 2 steps this has to be transformed to createinstance followed by an unwrap

#using <mscorlib.dll>
#include "stdafx.h"
using namespace System;
using namespace System::Reflection;

static void InstantiateINT32(bool ignoreCase) {
	try {
		AppDomain^  currentDomain = AppDomain::CurrentDomain;
		Object^ instance = currentDomain->CreateInstanceAndUnwrap("mscorlib",
			"SYSTEM.INT32",	
			ignoreCase,	
			BindingFlags::Default,
			nullptr,
			nullptr,
			nullptr,
			nullptr,
			nullptr);
		Console::WriteLine(instance->GetType());
	}
	catch (TypeLoadException^ e) {
		Console::WriteLine(e->Message);
	}
}

int main() {
	InstantiateINT32(false);     // Failed!
	InstantiateINT32(true);      // OK!
}

and this works nicely in VBA excel (early binding, no late binding) and helps in understanding the cor runtime as its easier walking thru in debugmode of VBA ide

just set the reference to mscoree.tlb and mscorlib.tlb (classes are case sensitive)

Sub test()
    Dim rt As mscoree.CorRuntimeHost
    Dim unk As stdole.IUnknown
    Dim ad As mscorlib.AppDomain
    Dim s As mscorlib.Stack
    
    Set rt = New mscoree.CorRuntimeHost
    rt.Start
    rt.GetDefaultDomain unk
    Set ad = unk
    Set s = ad.CreateInstance("mscorlib", "System.Collections.Stack").Unwrap
    s.Push "hello"
    s.Push "goodbye"
    s.Push 42
    
    MsgBox s.Pop
    MsgBox s.Pop
    MsgBox s.Pop
End Sub

this works not

Sub test2()
    Dim rt As mscoree.CorRuntimeHost
    Dim unk As stdole.IUnknown
    Dim ad As mscorlib.AppDomain
    Dim s As mscorlib.ObjectHandle
    
    
    Set rt = New mscoree.CorRuntimeHost
    rt.Start
    rt.GetDefaultDomain unk
    Set ad = unk
    'System.Runtime.Remoting.ObjectHandle
    Set s = ad.CreateInstance("mscorlib", "System.Int32") '.Unwrap
   ' .Unwrap
        
      
Debug.Print s

End Sub

First get it running in VBA and when found out how to do late binding with createinstance it should not be hard

fixed c++ code based on VS2015 CE

This is exactly the same for when investigating COM objects

Using the VBA Object browser gives you all the details you need about the methods / properties / events etc.

It's good workbench for testing indeed...

I will also do some more reading on this, but a bit short of time these days, so hold on for a while ...

Thanks for keeping this alive !

Using .NET libary with AutoIt, possible?
