[SOLVED] WinMenuSelectItem method cannot find in C#

[IgImAx]

Hi

 

UPDATED Notes: ===============================================================================

UPDATED: My main and second questions answered. Here the answers:

1. To add/access WinMenuSelectItem you need to [Thanks to Fernando_Marinho]:

• Add AutoItX.Dotnet in Manage NuGet Packages
• Right Click in your Project -> Add -> Reference... -> COM ( Type Libraries )than, check the option AutoItX3 1.0 Type Library 
• using AutoItX3Lib;
• AutoItX3 au3 = new AutoItX3();
• au3.WinMenuSelectItem("", ...)
• My full source code in C# exists in 11 posts in below.

1. How to access those overloaded methods in AutoitX3 that are not accessible via above method!? Or how to fix AutoitX3 DLL Registration need in target computers without Autoit pre-installed on them!? Please check my post at 14 posts below!

=============================================================================== Original Post:

 

 

I was writing a small app in Autoit to close µTorrent app. It was working. Then I try to import AutoItX into C#, but unfortunately this method

WinMenuSelectItem

Couldn't find by IntelliSense and If I typed completely it still give me this message:

Quote

'AutoitX' dose not contain a defination of 'WinMenuSelectItem'

Please check the image. I Google it and I found this QA at stackoverflow: Autoit error within C# application I saw they use this line:

au = new AutoItX3Lib.AutoItX3Class();

I figure it how to add 'AutoItX3Lib' to project (by adding 'AutoItX3.dll' to reference) but again! When I use this line:

var au = new AutoItX3Class();

I got this error message: Interop type 'AutoItX3Class' cannot be embedded. Use the applicable interface instead.

My system info:

Visual Studio 2017 Enterprise - v15.5.4

X64 Windows 10 Enterprise 1607

Thanks in advanced

Post code if you want help. There is a NuGet package for auto IT that works quite well

Hi Earthshine

Thanks for your fast reply!

I already posted code! (But in the image!  ) Here it is my code in VS2017:

using System;
using AutoIt;

namespace Send_key_commant_to_a_Window
{
    class Program 
    {
        static void Main()
        {
            IntPtr intPtr = AutoItX.WinGetHandle("µtorrent");
            if (intPtr != IntPtr.Zero)
            {
                // This line wont compile! This is error message:
                //  'AutoitX' does not contain a definition of 'WinMenuSelectItem'
                AutoItX.WinMenuSelectItem(intPtr, "", "&File", "E&xit");
            }

        }
    }
}

And here is my AutoIt Code(this working without any problem):

$hWin = WinGetHandle("μTorrent")
$result = WinMenuSelectItem($hWin, "", "&File", "E&xit")

Quote

There is a NuGet package for auto IT that works quite well

Thanks, I check it, there were two Autoitx and Autoitx.DotNet the first one gives me this error:

But second one, installed without any problem. But still it cannot find 'WinMenuSelectItem' method!

add comment at C# sample code.

[Earthshine]

Ok. I will take a look at it when I get back in the office tomorrow

[Earthshine]

yes, it says the same for me. that is not one of the methods. so, what exactly is it you want to do, just close uTorrent app? there is a ShutDown method

or you could just do this and not use autoit at all.

try
{
    foreach (Process proc in Process.GetProcessesByName("utorrent"))
            {
                proc.Kill();
            }
}
catch(Exception ex)
{
    MessageBox.Show(ex.Message);
}

Thanks Earthshine

Well! This was my first intention! To make sure that I added Autoit library in the right way!  Thanks to you now I know that I did it right!

So now I would like to report it ['WinMenuSelectItem' method does not exists in AutoItX] so developers team put its fix in their To Do list.

I even try to copy all dll's manually fromlatest Autoit directory too! Still no hope!

so, what exactly is it you want to do, just close uTorrent app?

It's not the right way to close some apps by killing their process! They may have some unsaved data and sometimes they do not need that a user save them first, they will do it automatically when the user chooses the Exit option. In this case (µtorrent) if you kill its process, at next startup, it will start checking all files in its download list and it will make hug disk usage.

 

But still there are some other issues  that force me to use 'WinMenuSelectItem' method. I have to send some key commands to µTorrent window, while the workstation is in Lock mode. In that case and based on this article 'Why doesn't my script work on a locked workstation?' only these commands will work: 

ControlSend()  ControlSetText()  ControlClick()  WinWait()  WinExists()  WinMenuSelectItem()

That's why I need to use 'WinMenuSelectItem' method to send menu commands to µTorrent, not only to close it in the right way, but also to set other options in its menu too like this one:

$hWin = WinGetHandle("μTorrent")
$result = WinMenuSelectItem($hWin, "", "&Options", "&Auto Shutdown", "Shutdown when Downloads Complete")

 

At the end you may ask why you are not using AutoIt itself (To write the code and compile)!? I prefer C# and VS environment! Anyway. Thanks for your help and I hope this method add to AutoitX.DotNet library in near future updates or bug fixes.

 

Cheers

some corrections

[Earthshine]

lol, how about this

using System;
using AutoIt;

namespace Send_key_commant_to_a_Window
{
    class Program
    {
        static void Main()
        {
            IntPtr intPtr = AutoItX.WinGetHandle("µtorrent");
            if (intPtr != IntPtr.Zero)
            {
                // This line wont compile! This is error message:
                //  'AutoitX' does not contain a definition of 'WinMenuSelectItem'
                //AutoItX.WinMenuSelectItem(intPtr, "", "&File", "E&xit");
                AutoItX.ProcessClose("µtorrent");
            }
        }
    }
}

and if you prefer C#, then you don't need autoit at all anyway.

[IgImAx]

ProcessClose() do the same thing that Process.kill do! Beside that I want to do other stuff I mention too!

lol don't get me wrong. I like to use AutoIt inside the VS not only the VS/C# to do automation. Autoit have many many many useful methods that if I want to write them with pure C# it's look like to inventing the bicycle again! And again!!! lol

[Earthshine]

then i suggest you use ControlSend and the like to automate the menu. it can probably be done.

[Fernando_Marinho]

Hi IgImAx,

 

You need :

• add AutoItX.Dotnet in Manage NuGet Packages ;
• add  to your code :

  using AutoItX3Lib;

• set instance, like :

AutoItX3 au3 = new AutoItX3();

than, call the method:

au3.WinMenuSelectItem("", ...)

 

Works for me !

Thanks! That is working 

 

But now I found another problem! Please look at bellow Code:

using System;
using AutoIt;
using AutoItX3Lib;

namespace SendKeyCommand
{
    internal static class Program 
    {
        private static void Main()
        {
            var au = new AutoItX3();

            var intPtr = AutoItX.WinGetHandle("μTorrent");
            if (intPtr != IntPtr.Zero)
            {
                // intPtrString will be equal to intPtr in Hex
                var intPtrString = "0x" + intPtr.ToString("X8");
                // Bellow line, Doesn't Work!!? Why!?
                au.WinMenuSelectItem(intPtrString, "", "&Options", "&Auto Shutdown", "Shutdown when Downloads Complete");
                // Bellow line, Will work
                au.WinMenuSelectItem("μTorrent", "", "&Options", "&Auto Shutdown", "Shutdown when Downloads Complete");
            }
        }
    }
}

This line with a window handle as first parameter will not work: au.WinMenuSelectItem(intPtrString, ...

While the next line with a title will work!

I checked this line: var intPtr = AutoItX.WinGetHandle("μTorrent"); and it finds the right handle, and when I convert it to string  it is in the right format. (I checked to make sure it converts it to string in right way, for instance, if intPtr is 0x0008074a its string will be the same "0x0008074a") 

 

So why is that line with window handle is not working!?

 

[BrewManNH]

Why not just use the handle returned by WinGetHandle instead of converting it into a string and manipulating it to get it back to the format it was in previously?

It does not accept intPtr as first parameter, won't compile!  please check the image:

 

 

I found these two lines in AutoitX3_DLL.h file:
 

AU3_API int WINAPI AU3_WinMenuSelectItem(LPCWSTR szTitle, /*[in,defaultvalue("")]*/LPCWSTR szText, LPCWSTR szItem1, LPCWSTR szItem2, LPCWSTR szItem3, LPCWSTR szItem4, LPCWSTR szItem5, LPCWSTR szItem6, LPCWSTR szItem7, LPCWSTR szItem8);

AU3_API int WINAPI AU3_WinMenuSelectItemByHandle(HWND hWnd, LPCWSTR szItem1, LPCWSTR szItem2, LPCWSTR szItem3, LPCWSTR szItem4, LPCWSTR szItem5, LPCWSTR szItem6, LPCWSTR szItem7, LPCWSTR szItem8);

Is it possible to use/access WinMenuSelectItemByHandle method!?

[IgImAx]

Hi everyone 

First, I like to thank you all for all help and specially Fernando_Marinho for his solution.

I found my answer on this topic: C# use of the dll, some idears for you. about how to use those overloaded methods with "...ByHandle" postfix that doesn't exist in AutoitX3 lib in C#. (If we add it via COM to project reference)

expandcollapse popup

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");
            }
        }
    }
}

Two important things:

1. Omit all "[MarshalAs(UnmanagedType.LPStr)]" parts.
2. No need to Register AutoItX3.DLL or AutoitX3_64.DLL files in the target computers. (Tested in VMware)
3. No need to Reference AutoItX3 1.0 Type Library in C# (unless you do not want to use above method!) Just adds AutoItX.Dotnet in Manage NuGet Packages or Reference AutoItX3.Assembly.dll  manually from AutoitX folder under the audit installation folder.

Thanks again everyone. Managers can kindly tag this topic as [ANSWERED] .
