MultiThreading UDF

[nekkutta]

I just created a UDF for doing Multithreading, seems to only work once the script is compiled, it's a bit messy, but I believe it should work fairly well, need some people to try it out.

The UDF:

;Multithreading Include
#include-once
Global Const $MultiThreadInt = 15684987214 ; created upon supply
Dim $MultiThreadParam1, $MultiThreadParam2, $MultiThreadParam3, $MultiThreadParam4, $MultiThreadParam5, $MultiThreadParam6, $MultiThreadParam7
If $CmdLine[0] <> 0 Then
    If $CmdLine[1] = $MultiThreadInt Then
        $MultiThreadFunctionName = $CmdLine[2]
        $MultiThreadNumOfParams = $CmdLine[0] - 2
        If $MultiThreadNumOfParams = 0 Then
            Call($MultiThreadFunctionName)
            Exit
        ElseIf $MultiThreadNumOfParams > 8 Then
            MsgBox(0, "Error", "Too Many Parameters")
            Exit
        Else
            For $i = 3 To $CmdLine[0]
                Assign("MultiThreadParam" & $i - 2, StringReplace($CmdLine[$i], '"', ''))
            Next
            Switch $MultiThreadNumOfParams
                Case 1
                    Call($MultiThreadFunctionName, $MultiThreadParam1)
                    Exit
                Case 2
                    Call($MultiThreadFunctionName, $MultiThreadParam1, $MultiThreadParam2)
                    Exit
                Case 3

                    Exit

    Local $NewThreadNumOfParams = 0
    For $i = 1 To 7
        If Eval("param" & $i) = "" Then ContinueLoop
        If IsHWnd(Eval("param" & $i)) Then Assign(Eval("param" & $i), String('0x' & Eval("param" & $i)))
        $NewThreadNumOfParams += 1
    Next
    If $NewThreadNumOfParams = 0 Then
        ShellExecute(@ScriptFullPath, $MultiThreadInt & ' ' & $sFunctionName , @ScriptDir, "", @SW_HIDE)
    Else
        Switch $NewThreadNumOfParams

        EndSwitch
    EndIf
EndFunc   ;==>NewThread

and a quick test script:

;multithread test
#include "Multithreading.au3"
Func One()
    MsgBox(0,'','One')
EndFunc
Func Two()
    MsgBox(0,'','Two')
EndFunc
Func Three()
    MsgBox(0,'','Three')
EndFunc
Func Four()
    MsgBox(0,'','Four')
EndFunc
Func Five()
    MsgBox(0,'','Five')
EndFunc
Func Six($sString)
    MsgBox(0,'Func Six', $sString)
EndFunc
_newthread("one")
_newthread("Two")
_newthread("Three")
_newthread("Four")
_newthread("Five")
_newthread("Six",InputBox('',''))

Let Me know what you think.

This is not multi-threading. It's multi-process which is two very different things. If you do a search for it you'll find you're not the first to explore this area >_

Ok, I'll grant you it isn't true multi-threading, but its probably the closest we're going to get with autoit, I tried doing a search, but I didn't really see anything that stood out from all the rest of the results junk. all I'm asking is a try out.

PS I really like your two-liner GUI

I am sorry, but this is the reason why it's can not work like multithreading, and thus can not be usefull:

;multithread test (failed?)
#include "Multithreading.au3"

$sVar = 1

_newthread("one")

Func One()
    MsgBox(0, $sVar, 'One')
EndFunc

$sVar is not declared in new process, it's can not be used >_<

;multithread test (failed?)
#include "Multithreading.au3"

$sVar = 1

_newthread("one")

Func One()
    MsgBox(0, $sVar, 'One')
EndFunc

$sVar is not declared in new process, it's can not be used >_<

This is why would would save all variables in a ini and let the scripts read them as it needs them.

This is why would would save all variables in a ini and let the scripts read them as it needs them.

It's still not usefull as multithreading >_<

I agree but was just giving some idea's

[arcker]

Agree, this is not multithreading.

I'm working on the trancexx solution and this is awesome.

BTW it needs some asm and C++ knowledge.

It took me one week to understand the trancexx code so multithread is possible but you need to work hard on it,

so the interest is limited since autoit is here to simplify our life >_<

try this:

#include "Multithreading.au3"

$sVar = 1

_newthread("one", $sVar)

Func One($funcVar = '')
    MsgBox(0, $funcVar, 'One')
EndFunc

[MrCreatoR]

try this:

And what if i have hundreds of these vars? No need to answer, it's a retorical question. This is still not the same as multithreading, where you can use the same runing environment in different processes.
