C# use of the dll, some idears for you.

JLeveille · March 30, 2009

This code looks to be a potential massive help for me. I am building a C# executable and cannot register the AutoIt dll on the target machine.

I was doing some testing of this technique versus the use of the registered DLL and I was surprised to find out that the two techniques gave different results. An example of this is when I called WinGetPosX and WinGetPosY. If I call using the registered DLL and a C# standard reference I get correct coordinates for the window. If I call using

AutoItX3Declarations.AU3_WinGetPosX

AutoItX3Declarations.AU3_WinGetPosY

I get a value of 1 returned by both of these functions.

Anybody got a guess as to what I might be missing or how I am shooting myself in the foot?

Oh, and BTW, I don't think that this odd result has anything to do with the code provided for AutoItX3Declarations in this thread. The reason I say that is because I was getting coordination of 1,1 for my window even before I switched from my own DLLImports to using the class provided here.

Hello JLeveille.

This is an example how I use the function in my code to do a mouse click:

AutoItX3Declarations.AU3_MouseClick("left"

, AutoItX3Declarations.AU3_MouseGetPosX()

, AutoItX3Declarations.AU3_MouseGetPosY()

, 1, 10);

Something else to consider is using AutoItX3Declarations.AU3_AutoItSetOption although I have never needed to.

It has and option called MouseCoordMode:

MouseCoordMode Sets the way coords are used in the mouse functions, either absolute coords or coords relative to the current active window:

0 = relative coords to the active window

1 = absolute screen coordinates (default)

2 = relative coords to the client area of the active window

John.

Hi John,

I have the same problem as JLeveille. I get an 1 for wingetposheight. I put the autoitsetoption in the init and its not working. In hte button click it doesn't work also. When I try your example it is working. Could you check it? I think its only not working for the getpos etc.

Thanks!

John,

Glad to see you are keeping up with this! I will be testing the new methods soon.

I was just wondering, has anyone had to access/control a datagrid using the autoit classes? When I Spy them, they don't seem be fully accessible.

Does anyone have an example of Datagrid access through managed code?

Roel.

Please send your code snippet to me at:

jdekker@xtra.co.nz

I will take a look at it.

Regards,

John.

Here is another thought for those having difficulty with returned values. I have not had to use this with AutoIt but it has helped me out with code that used external dll's.

Sometimes the Garbage collector can be too quick and you loose your data before it has been used. Seems that this should not happen yet .net provides us with the PINNED mehcanism.

int mouseposition;

GCHandle gchandle1 = GCHandle.Alloc(mouseposition, GCHandleType.Pinned); //prevent the GC from affecting the variable

mouseposition = AutoItX3Declarations.AU3_MouseGetPosX();

//use the value in mouseposition

gchandle1.Free(); //let the GC do his thing again

If it doesn't help here you may find it useful elsewhere.

Regards,

John.

The garbage collector won't collect referenced values. Especially not native types like ints.

Alynuzzu · May 30, 2009

If I want to add this "AutoItX3Lib.dll" at references and I will create a instance of the extern class "AutoItX3Declarations" on the beginning of any internal class (eg Form1() ) then when I need a function , must to call a function so:

int x = name_of_instance.AutoItX3Declarations.AU3_MouseGetPosX();

What can be the problem ???

I don`t like to use [DllImport]

Richard Robertson · May 30, 2009

If you are adding it as a reference, you are using the COM version. If you want the dll version, don't add a reference.

Second, you need DllImport to use a dll interface. There's no dodging that. You don't need any instance functions since dll imports should be static functions.

jcddcjjcd · June 3, 2009

Just paste the whole class supplied here into a new class you have created and named AutoItX3Declarations.cs This will become part or you project. Inside the supplied code change the "namespace IRhub" near the top to be the same as your own namespace then just use the code as in the examples near the top of the code.

Regards,

John.

Here is the class I use for autoit functions. Most of the au3 functions are wrapped/overloaded for easier use.
...the code...

Nice helpercode!!! One problem though. What is Bing_bot and how do i get the needed class for that?

why not put your code in the code tag

So does this approach require the DLL be installed/registered? I am trying to use AutoItX3.dll from C#. I have added the AutoItX3Declarations class to my Visual Studio solution and everything appears good there, but when executing the code I get a DLL not found error. From reading the first post I thought the idea of this approach was to not have to install/register the DLL. Visual Studio will not let me add a reference to the DLL as it gives me a "could not add reference" error.

I am writing a C#/Windows application that will be distributed to several hundred desktops and am looking to avoid installing AutoIt on each machine.

Markos · April 28, 2011

No need to register, but you must put the AutoItX dll in the path (next to exe or to any folder referenced by PATH variable), so it can be loaded at runtime

i have a massive problem here any help would be welcome.

i have a project which was based on your post i was using the 3.2.12 dll with a class that imports all the functions.

it was working fine in c# 2008 express and when i upgraded to 2010 ver the project also worked fine.

in another computer with the same setup, i installed c# 2010 without upgrading, and copied the project to a folder and then ran it.

no error are reported from c# the project runs normally, but ANY call to a autoit function simply doesn't do anything. not even WinActivate works.

any ideas??????

Hi.

I just noticed your post. I only check here very occasionally. I suggest you read through this entire thread, somewhere you will see that I updated the code, from memory I think is was when it supported unicode. You will need to use the 3.3 autoitx and the declarations I posted to go with it.

With the new declarations things will work again for you.

This is from memory, it you try all this and still have problems then post here again, I will keep and eye out.

Regards,

John.

Hey guys,

I can´t get this to work, I´m trying to use the ControlCommand function in C#, the dll import etc. works fine but i cant handle all the parameter for example:

AutoItX3Declarations.AU3_ControlCommand(string Title,string Text,string Control,string Command,string Extra,stringbuilder result,int buffsize);

could someone give me an example with all parameters...

regards Kraddler

Hi John. Funny to find you on here. I guess great minds think alike. Anyway, I like your declarations. Thanks for posting them. I have improved them by adding documentation for the parameters for most of the functions. Now the intellisense will provide some useful information.

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace AutoitxTest
{
    internal static class AutoItX
    {
        //NOTE: This is based on AutoItX v3.3.0.0 which is a Unicode version
        //NOTE: My comments usually have "jcd" appended where I am uncertain.
        //NOTE: Optional parameters are not supported in C# yet so fill in all fields even if just "".
        //NOTE: Be prepared to play around a bit with which fields need values and what those value are.
        //NOTE: In previous versions we used byte[] to return values like this:
        //byte[] returnclip = new byte[200]; //at least twice as long as the text string expected +2 for null, (Unicode is 2 bytes)
        //AutoItX3Declarations.AU3_ClipGet(returnclip, returnclip.Length);
        //clipdata = System.Text.Encoding.Unicode.GetString(returnclip).TrimEnd('\0');
        //Now we are returning Unicode we can use StringBuilder instead like this:
        //StringBuilder clip = new StringBuilder(); //passing a parameter here will not work, we must asign a length
        //clip.Length = 200; //the number of chars expected plus 1 for the terminating null
        //AutoItX3Declarations.AU3_ClipGet(clip,clip.Length);

        //The below constants were found by Registering AutoItX3.dll in Windows
        //, adding AutoItX3Lib to References in IDE
        //,declaring an instance of it like this:
        // AutoItX3Lib.AutoItX3 autoit;

        //,right clicking on the AutoItX3Class and then Goto Definitions
        //and seeing the equivalent of the below in the MetaData Window.
        //So far it is working
        //NOTE: easier way is to use "DLL Export Viewer" utility and get it to list Properties also
