ProcessClose in AutoItX3 version 3.3.12.0 not working

[takg]

I just installed version 3.3.12.0 of AutoItX3.dll and now ProcessClose does not work.

If I put version 3.2.10.0 back in,  it works.

Any idea what's going on?

I am using Windows 7 Pro.

Followup: I am closing using the process name (e.g. "notepad.exe") not the PID.

I forgot to say AutoitX3.dll. Sorry about that.

If nobody else can reproduce, I will try to post a sample. Everything works fine for compiled Autoit script. The problem is with the AutoitX3.dll

Probably best to post your code, and say if other Process* functions work, along with your OS details and language you're using.

[takg]

I will try to replicate the problem in a small program on Tuesday.

I am using Windows 7 SP1 Pro. Let me know what else you need to know.

The ProcessExists function does work.

I have tried Run As Administrator and that doesn't matter.

I don't have the manual for the AutoItX3.dll version 3.2.10.0. Has something changed since then?

Could this have something to do with closing the program that calls ProcessClose before the command has a chance to execute? I tried ProcessWaitClose but that didn't seem to work either.

[JohnOne]

I do not think anything changed from 10 to 12

I will try to replicate the behavior with a small app. This behavior happens with both a VB and a C# app.

[takg]

I am hoping someone can help me out. 

To do the test, I think a simple loop.exe for the app to close would work.

while 1

Sleep(1000)

wend

Now a script that loads the AutoItX3.dll and calls the ProcessClose function is needed. I have never used the DllCall function in AutoIt. Tutorial is here:

http://www.autoitscript.com/forum/index.php?app=core&module=attach&section=attach&attach_id=25713

Here is the function:

DllCall ( "dll", "return type", "function" [, "type1", param1 [, "type n", param n]] )

 

Would this work?

 

DllCall("AutoItX3.dll","void","AU3_ProcessClose","dword","loop.exe")

 

Could someone who knows how to use DllCall try this out? With AutoItX3.dll version 3.3.12.0 it will not work but with AutoItX3.dll version 3.2.10.0 it will work; namely, closing loop.exe.

 

This is to test the dll. I know it would be easier to just use AutoIt built-in ProcessClose function. I am using the dll in another development environment.

 

Also, if it works with both versions of the dll, I will have to post a sample from my development environment.

 

Please note that this is only a dll issue. Also, I have tried running as adminstrator and it doesn't fix the problem.

[JohnOne]

I just tried ProcessClose in AutoItX which is packed with AutoIt3 version 3.3.12.0 and it works just fine.

EDIT:

C#

namespace AutoItXTest
{
    class Program
    {
        static void Main(string[] args)
        {
            AutoItX.ProcessClose("PCTest.exe");
        }
    }
}

Are you really using AutoIt to DLLCall into AutoItX, or is that just being used as and example?

Because if you are, that's nuts.

[JohnOne]

Think it was just an example to make it easier for more people to test it.

Definitely works.

[takg]

Please read the entire thread carefully before commenting. The scripts below are just meant to show - in a convenient way - the problem with ProcessClose in 3.3.12.0 version of AutoItX3.dll.

Here is how to replicate the problem. 

You need two versions of the AutoItX3.dll (sorry, it won't let me attach so if you can't replicate it might be I have a corrupted version of the newer dll but other functions in the dll do work so I ruled this out): 3.3.12.0 and 3.2.10.0. Rename 3.3.12.0 to AutoItX3_new.dll and 3.2.10.0 to AutoItX3_old.dll.

Now, create a Loop.exe file using this:

while 1

Sleep(1000)

wend

 

Next, create a CloseLoop.exe using this script:

 

;Function declaration

;AU3_API int WINAPI AU3_ProcessClose(LPCWSTR szProcess);

 

;DllCall("AutoItX3_new.dll", "int", "AU3_ProcessClose","str", "Loop.exe")

 

DllCall("AutoItX3_old.dll", "int", "AU3_ProcessClose","str", "Loop.exe")

 

if @error Then

msgbox(0,"failed",@error)

    Else

msgbox(0,"success",@error)

endif

 

If you use the old dll, then it works. If you use the new dll, it does not.

[JohnOne]

AutoItX3 dll is meant for use in other language such as VB and C# as you mentioned, and said it does not work.

I'm here to tell you that it does.

I think you should post your whole C# code because you are obviously doing something wrong.

[takg]

Does this mean you can't replicate the problem with what I posted? If so, the only possibilities left in my view are that there is something wrong with my computer or the dll I have is corrupted. I will try re-downloading the dll and test on another computer.

My source code is irrelevant at this point because I can replicate the problem with what I have posted.

[takg]

I just tried re-downloading and installing AutoIt on a different computer. The same behavior is observed. Namely, when the old dll is used, the external Loop.exe is closed. When the new (re-downloaded) dll is used, the Loop.exe does not close.

So, at this point I strongly believe there is something wrong with the AutoItX3.dll version 3.3.12.0. 

I hope this helps someone. For now, I will continue to use the older version.

[JohnOne]

Works fine for me in AutoIt.

DllCall("AutoItX3.dll", "int", "AU3_ProcessClose","wstr", "Loop.exe")

[BrewManNH]

If you run that code as an x64 bit process, it won't work. If you run that code as an x86 process it works fine. If you run it as an x64 process and replace AutoItX3.dll with AutoItX3_x64.dll it runs fine.

Make sure you're running with the right DLL when you compile your program. If your program is an x64 program you'll see the same problem.

[takg]

BrewManNH --- I think that was it! My development computer is 64-bit. Thanks. I learned something today. I am not sure how this will affect things for me (namely, do I need x86 and x64 versions of everything? Or do I just need AutoItX3_x64.dll on 64-bit development machines?) but at least I have my work cut out for me now. Thanks again.

[BrewManNH]

Depending on what you're doing, you might only need an x86 version of your program to do it on both 64 bit and 32 bit operating systems.

[Richard Robertson]

BrewMan is right. Unless you have explicit reason to use 64 bit, it's much easier for everyone to develop only in 32 bit.
