Hi, I'm trying to add some new threads on a normal autoit executable

I found that the only way to do that is to use guiregistermsg and an internal message code

So I made this piece of script:

#Include <WinAPI.au3>
#include <WindowsConstants.au3>
Global $mymsg=_WinAPI_RegisterWindowMessage("MyNewMsg")
Global $uiui=GUICreate("uuu")
GUIRegisterMsg($mymsg,"lol")
Func lol($a,$b,$c,$d)
    MsgBox(0,$c,$d)
EndFunc
Sleep(1000)
_WinAPI_PostMessage ($uiui,$mymsg,"Hello","uuu")
While 1
    ;.....................................
WEnd

But msgbox displays only 0x000000000000

You can't add more threads to AutoIt. a function from GUIRegisterMsg interrupts the whole script until it's finished.

Try this.

#Include <WinAPI.au3>
#Include <WindowsConstants.au3>

Global $mymsg=_WinAPI_RegisterWindowMessage("MyNewMsg")
Global $uiui=GUICreate("uuu")

GUIRegisterMsg($mymsg,"lol")

Func lol($a,$b,$c,$d)
    
    local $tStruct = DllStructCreate('wchar[' & Number($d) & ']', $c)
    
    MsgBox(0, 'Test', DllStructGetData($tStruct, 1))
 EndFunc

Sleep(1000)

Global $sParam = "Hello"
Global $tStruct = DllStructCreate('wchar[' & String(StringLen($sParam) + 1) & ']')

DllStructSetData($tStruct, 1, $sParam)
_WinAPI_PostMessage($uiui, $mymsg, DllStructGetPtr($tStruct), DllStructGetSize($tStruct) / 2)
$tStruct = 0

While 1
    ;.....................................
WEnd

It might be worth pointing out that Yashied's example only works because you are reading with the same aplication that sent the message. If you were sending to another preocess then you would need to use the WM_COPYDATA message or use some memory functions.

tanks, it seems to work

but what ProgAndy wrote is true...

I can't have more than a main thread and an adlib

tanks all

Of course this will only work within the script. I just corrected the code. If you need to pass a string in another program then see the following.

Will be developed a version of autoit with threads?

I know that is really difficult to use threads (expecially for base-level developers)

but a special version with threads will help developers a lot!!!!!

No. The devs have even posted a note that this is one of the features that will not be developed and it should not to be requested.
