Pass variables from AutoITX C# to au3 script.

Recommended Posts


I have a question. I am making a Windows Form application with C#. I want to automate Chrome, I found out that it won't work properly with AutoITX. So I created a custom AutoIT script and I run it in my C# code. I want to give variables from my C# code to my normal AutoIT and use them there, is that possible? I tried copying a variable to my clipboard in C# and get it in my script, but I don't know how to copy the next variable to my clipboard. See below the code from my C# application.

  private static void AutoItTicket(Ticket ticket1)
            #region Alle variabelen naar notepad exporteren
            AutoItX.Run(@"C:\Program Files (x86)\AutoIt3\AutoIt3.exe /AutoIt3ExecuteScript setCompany.au3",@"C:\TicketScripts\", 1);

@Nine Thanks for your answer and sorry for my late reply.

I don't get it working. I need to pass C# variables to my au3 script, but I don't know the syntax. See the code below. for example I want to add $test to the au3 file, how does that look like?

$test = "Dynamic variable"

; Pass $test variable to the setCompany.au3
AutoItX.Run(@"C:\Program Files (x86)\AutoIt3\AutoIt3.exe, /AutoIt3ExecuteScript setCompany.au3", @"C:\TicketScripts\", 1);

Thanks in advance!

I do not have C#, but I will show you with AutoIt :


Func Example2()
  Local $oAutoIt = ObjCreate("AutoItX3.Control")
  Local $var = "This is a test"
  $oAutoIt.Run('"C:\Program Files (x86)\AutoIt3\AutoIt3.exe" /AutoIt3ExecuteScript "C:\Apps\Autoit\Test.au3" ' & _
    '"' & $var & '"', "", $oAutoIt.SW_SHOW)


#include <Constants.au3>

MsgBox ($MB_SYSTEMMODAL, $CmdLine[0], $CmdLine[1])

I'm not experienced with C#, but I can't imagine that it doesn't offer the ability to launch an executable without the use of a 3rd party library. Therefore, I'm confused about why you are trying to use AutoItX to launch an AutoIt script. Why not just use native C# for this?

P.S. Have you looked at the AutoItX help file entry for Run? To me, this command doesn't appear to support parameters.

here is how you do it. from the master @LarsJ


I am not sure if you can do it via the com object mate. I have used the methods below and it works for me.


@Nine, you do have .net installed most likely... lol you can use msbuild to build stuff in C# or any .NET language. it's fun! and they have SDKs  too if you really want to develop/debug via Visual Code

I've got the AutoITX included in my C#. So it's the other way around

so..., wassup Doc. :) 
Say, why not write an AutoIt script and IPC back and forth with the C# ?. It'll be better than all this AutoItX, as AutoIt has more stuff.  ( my 2 cents. )
