Using .NET libary with AutoIt, possible?

Recommended Posts

  • updated post 4 & 6 with some documentation/cleanup
     
  • A better interface definition for IAppdomainbased on some AIO Wrapper Generator stuff and manual changes. 
    Unsure how to validate (high level compared with MIDL) uncertain on types like variant
    should this get_ be removed? get_ToString --> ToString?
    when to use ptr* or object*?

  • Why is only from below the first line working?
Local $oAppDomain = ObjCreateInterface($pAppDomain, $sIID_IAppDomain, $sTag_IAppDomain)
;~          Local $oAppDomain = ObjCreateInterface($pAppDomain, $sIID_IAppDomain, Default)
;~          Local $oAppDomain = ObjCreateInterface($pAppDomain, $sIID_IAppDomain)

To me it looks a "normal" iUnknown and iDispatch see below MIDL part

Nice documentation cleanup... I will add post 4 & 6 to the other thread So that everyone can easily find it....

Thanks for the improved Interface code... is this already tested and can we update the UDF using this code or just wait for further testing ?

"The proof in the pudding "  As you know AutoIt comes with a .NET Assembly that Jon released a few years ago.

So I thought I would use PowerShell to dive into the Assembly and get any useful information regarding Data Types and more ...

Quote

CLS

$sFile = "C:\Program Files (x86)\AutoIt3\Beta\AutoItX\AutoItX3.Assembly.dll"

$assembly = [Reflection.Assembly]::Loadfile($sFile) 

$assembly.gettype().FullName

#$oAu3 = New-Object AutoIt.AutoItX (New Object does not work because it is not in the GAC)

[AutoIt.AutoItX].GUID

[AutoIt.AutoItX].Namespace

#[AutoIt.AutoItX].Assembly

#[AutoIt.AutoItX].BaseType

[AutoIt.AutoItX].Module

[AutoIt.AutoItX]::ClipPut("From AutoItX Assembly ! ")

$SRet = [AutoIt.AutoItX]::ClipGet()

write-host $SRet

Once we know the Data Types etc... we should be able to get this running using CLR correct ?

But unfortunately I did not get everything to work ... :(

;~  #AutoIt3Wrapper_UseX64=y
#include "CLR.Au3"

Example1()

Func Example1()
    Local $oAssembly = _CLR_LoadLibrary("C:\Program Files (x86)\AutoIt3\Beta\AutoItX\AutoItX3.Assembly.dll") ; Equals [Reflection.Assembly]::Loadfile()
    ConsoleWrite("!$oAssembly: " & IsObj($oAssembly) & @CRLF)

     Local $aText[] = ["We Love CLR !!"]

    local $oAu3X =_CLR_CreateObject($oAssembly,"AutoIt.AutoItX.ClipPut", CreateSafeArray($aText)) ; Equals [AutoIt.AutoItX]

    ConsoleWrite("!$oAu3X " & IsObj($oAu3X ) & @CRLF)
EndFunc

Example2()

Func Example2()
    Local $oAssembly = _CLR_LoadLibrary("C:\Program Files (x86)\AutoIt3\Beta\AutoItX\AutoItX3.Assembly.dll") ; Equals [Reflection.Assembly]::Loadfile()

    Local $pAssemblyType = 0
    $oAssembly.GetType_2("AutoIt.AutoItX", $pAssemblyType)
    ConsoleWrite("$pAssemblyType = " & Ptr($pAssemblyType) & @CRLF)

    Local $oAssemblyType = ObjCreateInterface($pAssemblyType, $sIID_IType, $sTag_IType)
    ConsoleWrite("IsObj( $oAssemblyType ) = " & IsObj($oAssemblyType) & @CRLF)

    Local $aText[] = ["We Love AutoIt !!"]
    Local $sClipBoardText = ""

    $oAssemblyType.InvokeMember_3("", 0x158, 0, 0, 0, 0)

;~     ConsoleWrite("Clipboard Data: " & ClipGet() & @CRLF)
    MsgBox(0,"[AutoIt.AutoItX]::ClipPut" , "Clipboard Data: " & ClipGet())
    sleep (1000)
    ClipPut("AutoIt Rocks!!!")

    $oAssemblyType.InvokeMember_3("ClipGet", 0x158, 0, 0, 0, $sClipBoardText)
    ConsoleWrite("Clipboard Data: " & $sClipBoardText & @CRLF)
    MsgBox(0,"[AutoIt.AutoItX]::ClipPut" , "New Clipboard Data: " & $sClipBoardText)

EndFunc   ;==>Example

What is confusing (and especially for other users that are not familiar with CLR) is :

Sometimes you need to use the first method Example1 using _CLR_CreateObject and sometimes Example 2 ObjCreateInterface method ?

I hope that this Example gives you a good idea on how to debug the CLR.au3 

A lot of things have to do with Data Type conversion between CLR and Variant Types apparently...

Some useful information I found when reading the Python CLR implemenation...

Also AHK tells it is not easy to get access to Static Methods in a straightforward way ?

It needs DllCalls inbetween ?

See this post and get to read the System.Math Examples at the bottom.

Quote

CLR_CreateObject is only for instantiating a class. Static methods like Math.Tan are difficult to call via COM as it requires...
[*:2252zeql]getting an instance of the Type object representing the type which contains the method,
[*:2252zeql]initializing a SAFEARRAY of VARIANTs containing parameters,
[*:2252zeql]calling the appropriate overload of Type.InvokeMember via a complicated DllCall, and
[*:2252zeql]interpreting the result VARIANT as necessary.For instance, this is a slightly modified (for readability) extract from CLR.ahk:


[color=darkgray]; pApp is a pointer to an AppDomain as returned by CLR_GetDefaultDomain()[/color]
p_App := COM_QueryInterface(pApp,"{05F696DC-2B29-3663-AD8B-C4389CF2A713}")
[color=darkgray]...[/color]
; Get typeof(Assembly) for calling static methods. (p_App->GetType()->Assembly->GetType())
DllCall(NumGet(NumGet(p_App+0)+40),"uint",p_App,"uint*",p_Type)
DllCall(NumGet(NumGet(p_Type+0)+80),"uint",p_Type,"uint*",p_Asm)
COM_Release(p_Type)
DllCall(NumGet(NumGet(p_Asm+0)+40),"uint",p_Asm,"uint*",p_Type)
COM_Release(p_Asm)

; Initialize VARIANTs & SAFEARRAY(VARIANT) for method args.
VarSetCapacity(vArg,16,0), NumPut(8,vArg), NumPut(psLib,vArg,8)
VarSetCapacity(vRet,16,0)
VarSetCapacity(rArgs,24,0), NumPut(1,NumPut(&vArg,NumPut(16,NumPut(1,rArgs))+4))

; Attempt to load from file.  (Call Assembly.LoadFrom().)
hr:=DllCall(NumGet(NumGet(p_Type+0)+228),"uint",p_Type
    ,"uint",COM_SysString(ws,"LoadFrom"),"int",0x118
    ,"uint",0,"int64",1,"int64",0,"uint",&rArgs,"uint",&vRet)

@ptrex:  interfaces I have tested with the examples and seems to work properly on my machine for the existing stuff. 

regarding autoit assembly did not know it exists so will study it.

Post 6 will nicely explain you from part 1-4 and inmore examples 5-8 how all this stuff works with Com. Then you will understand the logic of the calculation you see in AHK (and similar "magic" in AutoIt library).

will study your above post(s) later this week

OK I will make the interface mods to the UDF and test it, see if it makes any difference.

Regarding the logic, I understand but when you run my example in post 185, it does not make sense !  

Something is not working correctly in the UDF so far... 

Let's see which conclusions it bring you...

ptrex, Why do you think that creating an object as an instance of a class is the same as executing a static method which is not tied to an instance? I think it's obvious that these two different things should be implemented in two different ways.

Hi Larsj, Sure these are 2 different things I understand. The confusing part is coming from my (maybe too much PowerShell life in the meantime)

Once you create an Object you have access to the Methods / Properties etc.

in the CLR UDF you can create an instance of the .NET Object but you don't have access to the Methods / Properties etc persé ...

Like this example it make sense you load the assembly, create and instance to the object and you can access Class Types / Methods / Properties / ....

Func Example_FileInfo()
  Local $oAssembly = _CLR_LoadLibrary( "mscorlib" )
  Local $oFileInfo = _CLR_CreateObject( $oAssembly, "System.IO.FileInfo", @ScriptDir & "\tst02.txt" )
  ConsoleWrite( "IsObj( $oFileInfo ) = " & IsObj( $oFileInfo ) & @CRLF & @CRLF)
  $oFileInfo.Create()
;~   ConsoleWrite( $oFileInfo.Name & @CRLF)
  MsgBox(0,"System.IO.FileInfo","File Created :  " & $oFileInfo.Name )
EndFunc

I would expect the same approach here : you load the Assembly, create and instance to the object .....

Func Example1()
    Local $oAssembly = _CLR_LoadLibrary("C:\Program Files (x86)\AutoIt3\Beta\AutoItX\AutoItX3.Assembly.dll") 
    ConsoleWrite("!$oAssembly: " & IsObj($oAssembly) & @CRLF)

     Local $aText[] = ["We Love CLR !!"]

    local $oAu3X =_CLR_CreateObject($oAssembly,"AutoIt.AutoItX.ClipPut", CreateSafeArray($aText)) 

    ConsoleWrite("!$oAu3X " & IsObj($oAu3X ) & @CRLF)
EndFunc

Of course the second example does not create and instance to the object for whatever reason ?

The only difference between these 2 assemblies that the 1st one is registered in the GAC and the second one is not ?

But the main difference is that the first one has a COM interface and the second one has not ;)

because AutoItX is not comvisible  [assembly: ComVisible(false)] whereas system.io.fileinfo  [ComVisible(true)]

system.io.fileinfo is not reachable by objCreate by progid as its not in registry

but most likely you can do objcreate with the clsid (i will try, and if that works thats a better approach to instantiate .NET ComVisible then createInstance)

And then it would be interesting to better understand what objCreateInterface is doing internally
as I think it then tries to provide the missing interfaces to make it COM compliant again.

And last few weeks reading a lot but not found a nice reference that easily explains the main difference between a .NET interface and a .COM interface and why they are not just 100% interchangable (I understand offcourse wrapping will cause performance degradation but for scripting thats is normally not terrible)

Even the COM examples show the normal CoCreateInstance call takes an IID_ImanagedInterface and internally the CCW stuff handles the magic

// Initialize COM and create an instance of the InterfaceImplementation class:
   CoInitialize(NULL);
   HRESULT hr = CoCreateInstance(CLSID_InterfaceImplementation,
               NULL, CLSCTX_INPROC_SERVER,
               IID_IManagedInterface, reinterpret_cast<void**>(&cpi));

@ptrex Whats the question on this?  C# examples show static main so static methods just work

Changes:

I tested the Modification to the UDF function you proposed in post 183, and everything still works... So I will post a Version v2 in the other thread.

Together with the AutoIt.AutoItX Custom Assembly Example of ClipPut(), and the modified  .NET CLR Activator - GetType.au3 Example.

Clarifications :

Thanks a lot for the clarification on the different methods to use. In fact that is what I figured out last evening after I posted the examples in post 189 ...

Just for the record, basically you can say that :

COM Visible .NET Assemblies is called using _CLR_CreateObject() / comparable to Conventional COM object are called using ObjCreate()

Non COM Visible .NET Assemblies is called using ObjCreateInterfaceInvokeMember / comparable to WinAPI Libr. using DLLCall()

But this brings us to some more Questions : 

Why the ClipPut() works and the ClipGet() does not ?

Func Example2()
    Local $oAssembly = _CLR_LoadLibrary("C:\Program Files (x86)\AutoIt3\Beta\AutoItX\AutoItX3.Assembly.dll") ; Equals [Reflection.Assembly]::Loadfile()
    ConsoleWrite("$oAssembly: " & IsObj($oAssembly) & @CRLF)

    Local $pAssemblyType = 0
    $oAssembly.GetType_2("AutoIt.AutoItX", $pAssemblyType)
    ConsoleWrite("$pAssemblyType = " & Ptr($pAssemblyType) & @CRLF)

    Local $oAssemblyType = ObjCreateInterface($pAssemblyType, $sIID_IType, $sTag_IType)
    ConsoleWrite("IsObj( $oAssemblyType ) = " & IsObj($oAssemblyType) & @CRLF)

    Local $aText[] = ["We Love AutoIt !!"]
    Local $sClipBoardText = ""

    $oAssemblyType.InvokeMember_3("", 0x158, 0, 0, 0, 0)

    $oAssemblyType.InvokeMember_3("ClipPut", 0x158, 0, 0, CreateSafeArray($aText), 0)
;~     ConsoleWrite("Clipboard Data: " & ClipGet() & @CRLF)
    MsgBox(0,"[AutoIt.AutoItX]::ClipPut" , "Clipboard Data: " & ClipGet())
    sleep (1000)
    ClipPut("AutoIt Rocks!!!")

    $oAssemblyType.InvokeMember_3("ClipGet", 0x158, 0, 0, 0, $sClipBoardText) ; <===== DOES NOT WORK
    ConsoleWrite("Clipboard Data: " & $sClipBoardText & @CRLF)
    MsgBox(0,"[AutoIt.AutoItX]::ClipPut" , "New Clipboard Data: " & $sClipBoardText)

EndFunc   ;==>Example

Did I make a mistake or is there still bug in the UDF or is it because it can't reach the data outside of the au3 Process or ...

I am still trying to understand where things go wrong if they don't work as expected ...

The same thing happened if I use the RUN("Notepad.exe") method in the AutoItX assembly, nothing happens...

I was refering to the AHK simple example that was givin me issues too ?

Using the COM Visible Class Math, trying to get a simple "Math.PI" returned did not work... But I will look into this again... could be that I made a mistake somewhere.

So there are still bits and pieces that puzzle me, whereas this is working straight forward in PowerShell (this is my only benchmark at the moment).

So it's hard for me with out have all the under the hood documentation to pinpoint where it goes wrong...

N.B. Wouldn't it make sense to name the function _CLR_ObjCreate so it is in line with ObjCreate and ObjCreateInterface?

and after .net 2.0-4.7 we are back at coreclr with c-flat api's

If you follow all sourcerepositories and scan them a lot boils really down to CoCreateInstance that is also used in objCreate/objCreateInterface so will raise issue in AutoIt issue log to rename the AutoIt functions to CoCreateInstance :D. I don't care how we call them but if we have 3 then it should be clearly documented when and why to use any of them (or make a new function that wraps away the difference between the 3). For me thats still a mystery (after all posts in this thread and all manuals etc which was fun to read and learn) and I am trying to find out first for MSCORLIB and MSCOREE.

  • For objCreateInterface we should ask Jon or other developers whats the reason its still BETA as in this thread we also have examples that are based on objCreateInterface whereas some of them would be logical to write with CLR_CreateObject (calling createInstance methods)

@ptrex

not behind a computer with AutoIt but try this

Local $sClipBoardText = ["Now I am an array of text"]

The clipboard types you have to manage and as you put text on it as an array of characters it seems logical to assume you have to make it type array (and internally stuff with SAFEARRAY to array will be handled assumming that AutoIt internally has not SAFEARRAY but "normal"  c/c++ array). Could also be you have to make your variable preinitialized with a certain length of spaces / NULL values.

@junkew                                 

Thanks but it's the opposite side that does not work. The ClipPut() is OK, it is the ClipGet() from a regular clipboard value that does not work ... 

But no hurries. I will release only the AutoIt.AutoItX.ClipPut() for now... 

For the   .NET CLR Activator - GetType.au3 correction, I could not find the interface type in the UDF.au3, so that has to wait as well...

initial way of coding with cocreateinstance and c# example system.activator

https://www.codeproject.com/Articles/2615/DirectShow-NET

System.activator looks com visible so no clue why we cannot do objcreate with clsid. Progid is logical as its not registered as system.activator

://msdn.microsoft.com/en-us/library/system.activator.aspx

 

The answer regarding System.Activator looks to be in mscorlib_TLB.pas (Google for it)

IID__Activator: TGUID = '{03973551-57A1-3900-A2B5-9083E3FF2943}';
  CLASS_Activator: TGUID = '{9BA4FD4E-2BC2-31A0-B721-D17ABA5B12C3}';
...
  IID__ApplicationActivator: TGUID = '{D1204423-01F0-336A-8911-A7E8FBE185A3}';
...
 IID_IActivator: TGUID = '{C02BBB79-5AA8-390D-927F-717B7BFF06A1}';
 ...
 CLASS_ApplicationActivator: TGUID = '{1D09B407-A97F-378A-ACCB-82CA0082F9F3}';
 ...
 // Constants for enum ActivatorLevel
type
  ActivatorLevel = TOleEnum;
const
  ActivatorLevel_Construction = $00000004;
  ActivatorLevel_Context = $00000008;
  ActivatorLevel_AppDomain = $0000000C;
  ActivatorLevel_Process = $00000010;
  ActivatorLevel_Machine = $00000014;
 ...
   _Activator = interface;
  _AccessViolationException = interface;
  _AccessViolationExceptionDisp = dispinterface;
  _ApplicationActivator = interface;
  _ApplicationActivatorDisp = dispinterface;
  ...
    IActivator = interface;
  IActivatorDisp = dispinterface;
  ...
// *********************************************************************//

  CLRException = _Exception;
  Activator = _Activator;
  ....
  // *********************************************************************//
// Interface: IActivator
// Flags:     (4416) Dual OleAutomation Dispatchable
// GUID:      {C02BBB79-5AA8-390D-927F-717B7BFF06A1}
// *********************************************************************//
  IActivator = interface(IDispatch)
    ['{C02BBB79-5AA8-390D-927F-717B7BFF06A1}']
    function Get_NextActivator: IActivator; safecall;
    procedure _Set_NextActivator(const pRetVal: IActivator); safecall;
    function Activate(const msg: IConstructionCallMessage): IConstructionReturnMessage; safecall;
    function Get_level: ActivatorLevel; safecall;
    property NextActivator: IActivator read Get_NextActivator write _Set_NextActivator;
    property level: ActivatorLevel read Get_level;
  end;

// *********************************************************************//
// DispIntf:  IActivatorDisp
// Flags:     (4416) Dual OleAutomation Dispatchable
// GUID:      {C02BBB79-5AA8-390D-927F-717B7BFF06A1}
// *********************************************************************//
  IActivatorDisp = dispinterface
    ['{C02BBB79-5AA8-390D-927F-717B7BFF06A1}']
    property NextActivator: IActivator dispid 1610743808;
    function Activate(const msg: IConstructionCallMessage): IConstructionReturnMessage; dispid 1610743810;
    property level: ActivatorLevel readonly dispid 1610743811;
  end;

And this is then the part where the example is on instantiating the class in delphi (seems in the end then to use com function)

// *********************************************************************//
// The Class CoActivator provides a Create and CreateRemote method to          
// create instances of the default interface _Activator exposed by

// server of this typelibrary.                                            
// *********************************************************************//
  CoActivator = class
    class function Create: _Activator;
    class function CreateRemote(const MachineName: string): _Activator;
  end;

// *********************************************************************//
// The Class CoAppDomain provides a Create and CreateRemote method to          
// create instances of the default interface _AppDomain exposed by              
// the CoClass AppDomain. The functions are intended to be used by             
// clients wishing to automate the CoClass objects exposed by the

// *********************************************************************//
  CoAppDomain = class
    class function Create: _AppDomain;
    class function CreateRemote(const MachineName: string): _AppDomain;
  end;
class function CoActivator.Create: _Activator;
begin
  Result := CreateComObject(CLASS_Activator) as _Activator;
end;

updated post 199 with info on how to be able to create a object for System.Activator

Based on this I understand a little more but COM is not my native area.

Search for Activator in this source and it gets a little clearer

https://sourceforge.net/p/whitestaruml/code-0/270/tree/trunk/Imports/mscorlib_TLB.pas

As _Activator is hidden (and I assume its missing iDispatch) we have to do something similar with ObjCreateInterface or if it works like delphi it can just be a objcreate

      Dear members of the forum,
      I'm working on a project in which I have to use Image recognition technique. 
      Due to client restrictions, I couldn't use AutoIt for this project. 
      Is there a way to use this DLL "ImageSearchDLL.dll" (which is used to do image recognition steps in AutoIt) in VB.Net to achieve the same result? 
      I have used this DLL few years before and got good results. If there is a latest version of this DLL and if you can share it, that will be helpful too.
      Any guidance is deeply appreciated.

      Hi AutoIt Scripters/Programmers. I have a question about MIME Tools for Notepad++:
      I've recently found a UDF about Base64 in forum, but they can't decode\encode correctly some emojis , other UTFs and etc. so i decided to use mimeTools.dll of Notepad++ or main site
      My problem is how to use this dll in AutoIt Language?

      I will be happy with your comments and answers❤ Thanks.

      Good morning Forums 
      In these days, I am working on a project that involved me to use some Windows APIs to obtain some information about Terminal Servers.
      I'm doing this using wtsapi32.dll in a VBA Project, but, the lack of knowledge about few things threated in the articles make this quite difficult to
      implement and understand at the same time.
      The most difficult thing I'm facing is "translating" C/C++ functions or struct in VBA when pointers are used, or pointers of pointers, and so on.
      Since VBA seems to not have a pointer type, to make those functions work I need to implement other functions taken from other DLLs, and this confuses me a lot.
      For example, starting from this code, I splitted all the functions and all the definitions to understand why they are there, and why I need to use them.
      At the end, I've found out that the code I was going to implement starting from the functions provided in the Microsoft Docs won't be ever be able to work without some supplementary functions which are not mentioned anywhere.
      So, I was wondering if someone would please point me out to a good and practical exaplanation about pointers (in general) or specifically for VBA, because I need to use them quite often in these days, and I'd like to understand what I am doing.
      Thanks in advance.

      Best Regards and Stay at home 🏡

      Hello all!
      I got the Acroname Programmable USB Hub based on BrainStem platform. I will use it to manage ports and read current.
      They have development kit (BRAINSTEM DEVELOPMENT KIT) with examples for any languages like C#, C++, LabVIEW and python but no AutoIt.
      The kit include BrainStem2.dll (x32 and x64), BrainStem2_LabVIEW.dll, BrainStem2CLI.dll and many examples.
      Anyone used this dll and implemented it in AutoIt?
      Please share some example for Device Discovering, User LED Flashing or power enable/disable on port to start play with this HUB
