Using AutoIT with our registering the DLL

[SilentSnake]

Hi, 

 

on my target machine, i don´t have admin privileges. So I am looking for a way to make use of the autoit functionality without the need of register the dll with regsvr32. Does anybody have an idea? I already tried this way, but get an InvalidCastException. I am thankful for any hints or tips.

 

Best regards,

SilentSnake

You mean using activex object ?

I have no glue, I would use any method thad works.  I don´t know much about this autoit dll. Is it a question of individual usage, if it is an ActiveX object or a COM object? 

I built a minimal visual studio project to show my problem: https://teimotronic.de:501/sharing/pilOiMudv

Steps to reproduce: 

1. register the autoitx3.dll in the console with admin rights (regsvr32 autoitx3.dll)
2. Build the project and run it. It should work fine. 
3. Unregister the dll (regsvr32 -u autoitx3.dll)
4. Start the previous built version and see the exception. It complains about a missing interface. Does anybody has an idea?

I think you should to read this:

But I'm not VisualStudio user... (nor C, C++ , C#) so my hint may not be the right ones.

It has to be registered or you can't call it's methods and whatnot. I hate COM anyway. you can easily register it on client machines though, so what's the problem? distribute it with your app and register it.

you need to go read about COM and how it works. I don't think anyone around here will help with bypassing any kind of security btw.

Hi SilentSnake

I know this it old topic, but I was searching for same question in last week and I found my answer in some stackoverflow posts and one old topic on here. So for others that seeking for the same question, I hope this will help you:

You do not need to register AutoItX3.DLL or AutoitX3_64.DLL files in the target computers. In this old topic show how to use methods inside those two dll's directly: C# use of the dll, some idears for you. and I use same way in my simple app in C# and test it on other computers without registering any dll.

using System;
using System.Runtime.InteropServices;
using AutoIt;

namespace SendKeyCommand
{
    internal static class Program 
    {
        [DllImport("AutoItX3.dll", SetLastError = true, CharSet = CharSet.Auto)]
        private static extern int AU3_WinMenuSelectItemByHandle(IntPtr intPtr
            ,  string item1
            ,  string item2 = ""
            ,  string item3 = ""
            ,  string item4 = ""
            ,  string item5 = ""
            ,  string item6 = ""
            ,  string item7 = ""
            ,  string item8 = "");

        [DllImport("AutoItX3.dll", SetLastError = true, CharSet = CharSet.Auto)]
        private static extern int AU3_WinMenuSelectItem(string title
            ,  string text
            ,  string item1
            ,  string item2 = ""
            ,  string item3 = ""
            ,  string item4 = ""
            ,  string item5 = ""
            ,  string item6 = ""
            ,  string item7 = ""
            ,  string item8 = "");

        private static void Main()
        {
            var intPtr = AutoItX.WinGetHandle("μTorrent");
            if (intPtr != IntPtr.Zero)
            {
                AU3_WinMenuSelectItemByHandle(intPtr, "&File", "E&xit");
                // Or:
                // AU3_WinMenuSelectItem("μTorrent", "", "&File", "E&xit");
            }
        }
    }
}

All methods in these two libraries "AutoItX3.DLL or AutoitX3_64.DLL" listed inside of AutoItX3_DLL.h file under Autoit\AutoitX3 folder.

Note this: There are some methods with postfix "...ByHandle" they are overloaded methods that we do not use them with that name in Autoit but you have to specify them in C# just like I did in above sample on "AU3_WinMenuSelectItemByHandle" method.

Still, you can add a reference to this "AutoItX3.Assembly.dll" file without any problem. This file does not need any registration on target computers. [I think] You can do the same thing for any *.dll by using DllImportAttribute [DllImport("DllFilename")]. For more info :MSDN DllImportAttribute.

For more info please check my solved problem: "[SOLVED] WinMenuSelectItem method cannot find in C#"

 

Happy Coding!
