PHP Code:
Func GetThreadStartAddress($hThread)
    $StartAddress = DllStructCreate("DWORD")
    If @error Then Return SetError(1, "", False)

    $ntdll = DllOpen("ntdll.dll")
    If @error Then Return SetError(2, "", False)

    DllCall($ntdll, "none", "NtQueryInformationThread", "HANDLE", $hThread, "int", 9, "ptr", DllStructGetPtr($StartAddress), "int", 4, "int", 0)
    If @error Then Return SetError(3, "", False)

    Return SetError(0, "", DllStructGetData($StartAddress, 1))

here is the code for get the thread(TID's) from PID, I need get the StartAddress from the TID's returned, thank you for help!

PHP Code:

$pid = ProcessExists("game.exe")

$arr=_GetAllProcessThreads($pid)

_ArrayDisplay($arr)

Func _GetAllProcessThreads($iPid)
        $call = DllCall("Kernel32.dll", "ptr", "CreateToolhelp32Snapshot", "dword", $TH32CS_SNAPTHREAD, "dword", 0)
    $handle = $call[0]
    Local $RetArr[1][1]
    ConsoleWrite("Handle: " & $handle & @CRLF)

    $te32=DllStructCreate($THREADENTRY32)
    DllStructSetData($te32,"dwSize",DllStructGetSize($te32))
    $call=DllCall("Kernel32.dll","int","Thread32First","ptr",$handle,"ptr",DllStructGetPtr($te32))
    If DllStructGetData($te32,"th32OwnerProcessID")=$iPid Then _GetAllThreads_ArrHelper($RetArr,$te32)
    Do
        $call=DllCall("Kernel32.dll","int","Thread32Next","ptr",$handle,"ptr",DllStructGetPtr($te32))
        If Not $call[0] Then ExitLoop
        If DllStructGetData($te32,"th32OwnerProcessID")=$iPid Then  _GetAllThreads_ArrHelper($RetArr,$te32)
    Until True And False
    _ArrayDelete($RetArr,0)
    _WinAPI_CloseHandle($handle)
    Return $RetArr
EndFunc


Func _GetAllThreads_ArrHelper(ByRef $Arr,$TE32_Struct)
    $ub=Ubound($Arr)
    ReDim $Arr[$ub+1][1]
    $Arr[$ub][0]=DllStructGetData($TE32_Struct,"th32ThreadId")

Use "OpenThread" to get the required handle.

Example:

You have to compile the script as a 32 bit application. Otherwise the returned StartAddress will be 0.
