Very Simple Inter-Process Communication (using AutoItObject_Internal)

[SEuBo]

Hi there,

while I created an example script to generate and execute a function during runtime, I stumbled across a neat way to share data between running autoit scripts.
This is done using the amazing magic of  AutoItObject_Internal . (You'll need at least Version 3.0.0 of AutoItObject_Internal)

Using this UDF, you can create a shared data storage, basically an empty "AutoitObject_Internal-"Object which you can then use to write / read data Inline. no set/get methods, just

#include "AutoItSharedData.au3"
$oShare = _AutoIt_SharedData_CreateOrAttach("MyCustomID")
$oShare.some_data = 'foo'

and you're done. any other script accessing this data will have to do:

#include "AutoItSharedData.au3"
$oShare = _AutoIt_SharedData_CreateOrAttach("MyCustomID")
ConsoleWrite($oShare.some_data & @LF)

 

Basically it's Larsj's Implementing IRunningObjectTable Interface, but you dont have a Dictionary, but an IDIspatch Object instead.

There are already a bunch of IPC options available - and this is another one.

Feedback and/or improvements appreciated

 

changelog

version 2.0

• Removed need for AutoItObject, as AutoItObject_Internal now comes with ROT support
• Added UDF Header
• Fixed typo on "#include AutoItObjectInternal.au3" -> "#include AutoItObject_Internal.au3"
• Added ObjGet() after registering the object fails (in case 2 programs tried to register the same ID simultaneously)
• Updated Examples & zip archive.

I didn't tested it yet, but can we pass arrays, objects that way?

Hey,

yes you can, see example for array & object (in array) below - I think problems only really occur with DLLStructs, Pointers and Function-References. Some types (like handles) have to be Hwnd()'ed again on the other side. As far as I understood, those are internal limitations. Larsj did a great job summarizing it here (scroll down to "data types"):

$aArray :     Array variable type.
$dBinary :    Binary variable type.
$bBoolean :   Bool variable type.
$pPtr :       Int32 variable type.
$hWnd :       Int32 variable type.
$iInt :       Int32 variable type.
$fFloat :     Double variable type.
$oObject :    Object variable type.
$sString :    String variable type.
$tStruct :    Not recognized as a valid variable type.
$vKeyword :   Keyword variable type.
fuMsgBox :    Not recognized as a valid variable type.
$fuFunc :     Not recognized as a valid variable type.
$fuUserFunc : Not recognized as a valid variable type.

Great, i will test it soon, thanks for sharing!

[SEuBo]

New Version.

Since AutoItObject Internal now comes with ROT support, I removed the need for AutoItObject. No Dlls anymore, and most notably: 64-Bit support. Archive in first post updated.

 

[TheSaint]

Thanks for sharing. Intriguing stuff that I just might use one day ... I see the possibilities.

Of course, like many I suspect, I have shared data between programs using an INI file entry or a Registry entry, probably even via SQL. I've also done it using STDOUT and STDIN by compiling to a console based executable. Your project however seemingly promises more and better.

Thanks for you kind words. I didn't do much but to stumble accross this (Even a blind squirrel finds a nut once in a while ) but I am glad you like it!

All credits go to @genius257 for AutoItObject_Internal and of course to the original AutoItObject-Team for their great effort.

From me as well : "Thanks for sharing"

That is true, but it makes a big difference whether the nut is made of gold or is rotten. Moreover, finding something is only the first step. There must also be someone willing to spend his time to prepare something delicious from it (as you did) .

[frank10]

Thank you SEuBo, very useful!

I found these limits with array:

you can set and change a string/number var etc, you can read array, but you can't set/change an array and you can't directly use UDF _array: i.e. _arrayDisplay($oShare.arr)

#include "AutoItShared/AutoItSharedData.au3"
#include <Array.au3>

$oShare = _AutoIt_SharedData_CreateOrAttach("MyCustomID")

$oShare.data = 'foo'

global $arr = [1,2]
;global $oShare.arr = [1,2] ; NO

$arr[1] = 4
$oShare.arr = $arr
msgbox(0,'', $oShare.arr[1]) ; OK
;~ $oShare.arr[1] = 5 ; NO

_arrayDisplay($arr) ; OK
;~ _arrayDisplay($oShare.arr) ; NO

can you overcome these?

[SEuBo]

Hey frank10,

those are unfortunately limitations of the AutoIt Parser, as far as I understand. 

I guess you have no chance, but to use a temporary variable.

 

Regarding the direct access of Array-Elements for writing, there is a potential workaround, which is still not pretty.
We could "fake" a method for all the Array data. This would be done by replacing your AutoItSharedData.au3 with the following file (for testing purposes:)

Instead of

;~ $oShare.arr[1] = 5 ; NO

you could then write:

$oShare.arr(1) = 5

 

Not great, but at least something.

Great, a lot better!

It works also with 2D array:

global $arr = [[1,2],[3,4]]
$arr[1][0] = 8
$oShare.arr = $arr
$oShare.arr(1,1) = 9 

$temp = $oShare.arr
_arrayDisplay($temp)

 

[Nine]

Could you explain why I am receiving this error : "The requested action with this object failed"

 

Test1.au3 :

#include "AutoItSharedData.au3"

$oShare = _AutoIt_SharedData_CreateOrAttach("MyCustomID")

$oShare.Request = @MSEC

Do
    Sleep(10)
Until $oShare.Response

MsgBox(64,"",$oShare.Request & "/" & $oShare.Response)

Test2.au3 :

#include <AutoItSharedData.au3>

$oShare = _AutoIt_SharedData_CreateOrAttach("MyCustomID")

Do
    Sleep(10)
Until $oShare.Request

$oShare.Response = @MSEC

If I run Test2 first, and then Test1 I get the error.

Hi Nine,

contrary to what I've said in the first post about "the first script accessing a variable":

My best guess is that because Test2.au3 is the last script to assign any value within $oShare, it becomes the "Server" for this IDispatch.
Even though the behaviour isn't really consistent. I'd have to dig into that.

Potential workarounds:

1) Add Sleep(100) as last line of Test2.au3, like so:

#include <AutoItSharedData.au3>

$oShare = _AutoIt_SharedData_CreateOrAttach("MyCustomID")

Do
    Sleep(10)
Until $oShare.Request

$oShare.Response = @MSEC
Sleep(100)

2) OR: Add Error-Handler into Scripts, like so:

#include "AutoItSharedData.au3"

$oShare = _AutoIt_SharedData_CreateOrAttach("MyCustomID")
$oError = ObjEvent("AutoIt.Error", _ErrorHandler)

$oShare.Request = @MSEC

Do
    Sleep(10)
Until $oShare.Response

MsgBox(64,"",$oShare.Request & "/" & $oShare.Response)


func _ErrorHandler($oObject)
    SetError($oObject.number)
EndFunc

 

I'll investigate this later today.

Cheers,

[frank10]

There is also a problem with handles:

local $hWin = WinGetHandle("[active]")
$oShare.hGUImain  = $hWin ; it also stores it in Decimal...
ConsoleWrite($hWin & "___" & Hex($oShare.hGUImain) & @CRLF)
Local $aGUI_Main_Pos = WinGetPos($hWin)
ConsoleWrite("Pos hWin:"  & $aGUI_Main_Pos[0]  & @CRLF)

Local $aGUI_Main_Pos = WinGetPos($oShare.hGUImain)
ConsoleWrite("Pos oShare:"  & $aGUI_Main_Pos[0] & @CRLF) ; ERR
 
Local $aGUI_Main_Pos = WinGetPos( HWND($oShare.hGUImain) ) ; THIS works
ConsoleWrite("Pos oShare:"  & $aGUI_Main_Pos[0] & @CRLF) ; OK

EDIT

You should detect if there is a handle and store it as 0xHexNumber into the share var.

I would like to change some control settings of a GUI created from another script.

I got Get/Set with ControlGetText and ControlSetText, because original funcs like GUICtrlRead does not work in the script that didn't create the GUI.

Is there a way to use those original funcs also in the other script?

i.e. GUICtrlSetBkColor or GUICtrlSetImage

Is there a limit on the number and long of "variables"?
I mean $oShare.xxx.

Is there a command to erase the values of all variables of $oShare ?

This is the first time I have used AutoitObject.
I'm not sure if my question is related to this UDF, or if it is a more general question about Objects.
I'll ask here. Help me 🙂.
How to set the name and value of an object variable through function parameters?

#include "AutoItSharedData.au3"
$oShare = _AutoIt_SharedData_CreateOrAttach("MyCustomID")

_SharingSetData("1", "aaa")

Func _SharingSetData($Var, $String)

    $oShare.Variable($Var) = $String

    MsgBox(0,"", $oShare.Variable1)
EndFunc

I decided with the help of an array.

#include "AutoItSharedData.au3"
$oShare = _AutoIt_SharedData_CreateOrAttach("MyCustomID")

_SharingSetData("1", "aaa")

Func _SharingSetData($Var, $String)
    Local $arr[1]
    $oShare.Variable = $arr
    $oShare.Variable($Var) = $String

    MsgBox(0,"", $oShare.Variable($Var))
EndFunc
