@AutoItPID

this is my code, do you know what im doing wrong?

expandcollapse popup

#include 'authread.au3'
Global $Paused = True
Local $iPIDA,$iPIDB
HotKeySet("{p}", "TogglePause")

_AuThread_Startup()

$hThread = _AuThread_StartThread("myThreadFunction")
$hThreadb = _AuThread_StartThread("myThreadFunction2")

While True

    While $Paused
        Sleep(100)
        $msgA = _AuThread_GetMessage($iPIDB) ;this is the problem
        If $msgA Then
            ToolTip($msgA,0,0)
            Sleep(100)
        EndIf

    WEnd

WEnd

Func myThreadFunction()

    While True

        Global $iPIDA = @AutoItPID
        $threading = PixelGetColor(37, 215,0) ;desktop icon
        If ($threading = 0x6E7B9D) Then
            ToolTip($iPIDA,0,50)
            _AuThread_SendMessage(_AuThread_MainThread(),'no')
        Else
            ToolTip($iPIDA,0,50)
            _AuThread_SendMessage(_AuThread_MainThread(),'yes')
        EndIf

    WEnd

EndFunc

Func myThreadFunction2()

    While True

        Global $iPIDB = @AutoItPID
        $threadingb = PixelGetColor(28, 317,0) ;other desktop icon
        If ($threadingb = 0x7E718D) Then
            ToolTip($iPIDB,0,100)
            _AuThread_SendMessage(_AuThread_MainThread(),'no-no')
        Else
            ToolTip($iPIDB,0,100)
            _AuThread_SendMessage(_AuThread_MainThread(),'yes-yes')
        EndIf
