nomad's memory doesn't work?

5 posts in this topic

Nomad's memory doesn't work with windows 7 x64 with latest AutoIt? Addresses are ok, but MemoryRead() doesn't return me anything.

I am running it with admin privilegs, but still no effect. Any ideas?

Script

Global $D2Client = 0x6FAB0000
Global $pAct = 0x11C3B8
Global $Room1 = 0x10
Global $PosX = 0x4C
Global $PosY = 0x50

$pID = ProcessExists("game.exe")
$Open = _MemoryOpen($pID)
$Val = $D2Client + $pAct
$P1 = Hex(_MemoryRead($Val, $Open) + $Room1)
$P1o = '0x' & $P1
$P2 = _MemoryRead($P1o, $Open)
$Val2 = Hex($P2 + $PosX) ; This is where you designate whether it returns PosX or PosY
$Val2o = '0x' & $Val2
$Ret = _MemoryRead($Val2o, $Open)
MsgBox(1, "Room1", $Ret)

Nomad's memory for those who don't have this.

; AutoIt Version:   3.1.127 (beta)
; Language:         English
; Platform:         All Windows
; Author:           Nomad
; Requirements:     These functions will only work with beta.

;==================================================================================

; Functions:
;
;==================================================================================
; Function:         _MemoryOpen($iv_Pid[, $iv_DesiredAccess[, $iv_InheritHandle]])
; Description:      Opens a process and enables all possible access rights to the
;                   process.  The Process ID of the process is used to specify which
;                   process to open.  You must call this function before calling
;                   _MemoryClose(), _MemoryRead(), or _MemoryWrite().
; Parameter(s):     $iv_Pid - The Process ID of the program you want to open.
;                   $iv_DesiredAccess - (optional) Set to 0x1F0FFF by default, which
;                                       enables all possible access rights to the
;                                       process specified by the Process ID.
;                   $iv_InheritHandle - (optional) If this value is TRUE, all processes
;                                       created by this process will inherit the access
;                                       handle.  Set to 1 (TRUE) by default.  Set to 0
;                                       if you want it FALSE.
; Requirement(s):   None.
; Return Value(s):  On Success - Returns an array containing the Dll handle and an
;                                open handle to the specified process.
;                   On Failure - Returns 0
;                   @Error - 0 = No error.
;                            1 = Invalid $iv_Pid.
;                            2 = Failed to open Kernel32.dll.

The module isn't 64-bit friendly . Run it in 32-bit mode and use only on 32-bit processes.

game.exe is 32 bit app and when I installed Autoit I told installer to use 32 bit stuff (I think it's what you suggested (both binaries (autoit and game) is 32 bit)). Anything other I need to change?

I also fund that _WinAPI_OpenProcess(0x0010, 1, ProcessExists("game.exe")) fails only if process name is "game.exe" but sucess with any other process (tested with vlc.exe,explorer.exe)

I don't think you need the 2nd parameter set to 1, but I don't think that would cause it to fail. It could be that you need higher privileges to open that process. The 4th parameter to _WinAPI_OpenProcess() will try to get you Debug security privileges and open it that way. That might mean your script might need to be run in Administrator mode, I'm not sure.

I thought for sure that most games run in the same session and with the same privileges though? That seems odd. You might want to double-check that the game is 32-bit. My Process Functions UDF has a GUI that will let you try opening processes and running all kinds of little tests on them (see signature).
