AutoIT – Visual Studio Light

August 24, 2014

Sometime you find some nice code on the internet like VB.Net or C#.

But it is of no use if it is not compiled Sad smile

As explained in this post you can compile you own .NET COM objects on the fly.

But if you want to do it using a GUI interface without installing the full blown Visual Studio. You can use this GUI Wrapper – Visual Studio Light


The first option is for compiling GUI Applications EXE’s.

The second one is to create DLL’s (Libraries) which you can use later on in a .Net application.

The third one is for compiling Console Applications EXE’s.

You can download it here

PS :  This wrapper is for VB.Net but can easily be changed to use C# replace the vbc.exe by csc.exe

If you run it you get an EXE or DLL



This is the code :

imports System.Windows.Forms

' The name of the module must match the name of the code item
' created in the hosting application via CreateItem.
module Script
  sub Main()
    MessageBox.Show("hi From DotNET !!")
  end sub
end module

Using AutoIT to compile your own .NET COM Object

August 24, 2014

Wouldn’t it be nice to compile your own .NET COM DLL and use it on AutoIT.

Well we don’t need much to do this. Everything is available on your system.

Let’s see :

First we need of course some VB.Net code or C# that will exposes some methods or properties.

Imports System.Collections.Generic
Imports System.Text
Imports System.Runtime.InteropServices

Namespace myDotNetLibrary
  <classinterface   (CLASSINTERFACETYPE.AUTODUAL)> _
  Public Class myDotNetClass
    Private myProperty As String

    Public Sub New()
    End Sub

    Public Function myDotNetMethod(input As String) As String
      Return "Hello " & input
    End Function

    Public Property myDotNetProperty() As String
        Return myProperty
      End Get
      Set(ByVal value As String)
        myProperty = value
      End Set
    End Property

  End Class
End Namespace

Next we need a .Net compiler ? Ha but that is default available on each system that has a .Net Framework installed Smile

Go and have a look here : C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\vbc.exe

The vbc.exe is the compiler for the .Net 2.0 framework. But you will find as well the compiler for .NET 3.0 and 4.0 if you have that framework installed.

So now we need to compile the code to a DLL and register it.


; Framework 2.0
;$vbc = "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\vbc.exe" ;  ; check the path of your version
;$RegAsm = "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\RegAsm.exe" ; check the path of your version
; Framework 4.0
$vbc = "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\vbc.exe" ;  ; check the path of your version
$RegAsm = "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" ; check the path of your version

RunWait($vbc & " /target:library hello.vb", @ScriptDir, @SW_HIDE) ; compile the .net DLL
RunWait($RegAsm & " /codebase hello.dll", @ScriptDir, @SW_HIDE) ; register the .net DLL

$obj = ObjCreate("myDotNetLibrary.myDotNetClass")
$obj.myDotNetProperty = " ... from DotNet to the AutoIt World !"

MsgBox(0,"My Own DotNet Object " , $obj.myDotNetMethod($obj.myDotNetProperty) & @CRLF)

RunWait($RegAsm & " /unregister hello.dll", @ScriptDir, @SW_HIDE) ; unregister the .net DLL

Ones you run the code it will compile the code to a DLL and register it in the GAC

Or if you want don’t want to register the COM Assembly to the GAC, you can use this approach 😉



And run it as a COM object, where AU3 will access it’s methods and properties.


You can see if the COM object registered correctly here :


For a C# compiler you need to look for the csc.exe instead of the vbc.exe
