SetPrivilege Fails in NomadMemory.au3

Recommended Posts


I wonder if someone here can help me.

At the moment, im writing a little prog that reads various addresses in a game.

When i use it with notepad it works fine, when i use it with the game, the value always returns zero.

After researching i have found that SetPrivilege seems to be faulty.

To back up my conclusion i used a program called "permedit.exe" to grant permissions to my au3 file, which in turn allowed it to give me the correct value as a result.

Therefore im assuming SetPriilege in NomadMemory.au3 doesnt work quite how it should.

Is there anyway to set permissions correctly on my au3 file without having to use an external program to do so?

BTW im using Win XP

And here is my source.

#include <String.au3>
SetPrivilege("SeDebugPrivilege", 1)

Global $Start = 0

While 1
    If $Start = 1 then call ("_Start")
    Sleep (200)

Func ToggleStart()
    $Start = Not $Start

Func _Start()
$proc = ProcessExists("Game.exe")
        If Not $proc Then
        MsgBox(0, "Error", "Process is not open, please run it first.")
    If @Error Then
        MsgBox(0, "ERROR", "Failed to open memory")
    $charname = _MemoryRead($address, $ID, 'short')
    MsgBox(0,"Current HP",$charname)
    $Start = 0

Here is the section of NomadMemory.au3 thats in question

Func SetPrivilege( $privilege, $bEnable )
    Const $TOKEN_QUERY = 0x0008
    Const $SE_PRIVILEGE_ENABLED = 0x0002
    Local $hToken, $SP_auxret, $SP_ret, $hCurrProcess, $nTokens, $nTokenIndex, $priv
    $nTokens = 1
    $LUID = DLLStructCreate("dword;int")
    If IsArray($privilege) Then $nTokens = UBound($privilege)
    $TOKEN_PRIVILEGES = DLLStructCreate("dword;dword[" & (3 * $nTokens) & "]")
    $NEWTOKEN_PRIVILEGES = DLLStructCreate("dword;dword[" & (3 * $nTokens) & "]")
    $hCurrProcess = DLLCall("kernel32.dll","hwnd","GetCurrentProcess")
    $SP_auxret = DLLCall("advapi32.dll","int","OpenProcessToken","hwnd",$hCurrProcess[0],   _
    If $SP_auxret[0] Then
        $hToken = $SP_auxret[3]
        $nTokenIndex = 1
        While $nTokenIndex <= $nTokens
            If IsArray($privilege) Then
                $priv = $privilege[$nTokenIndex-1]
                $priv = $privilege
            $ret = DLLCall("advapi32.dll","int","LookupPrivilegeValue","str","","str",$priv,   _
            If $ret[0] Then
                If $bEnable Then
                    DLLStructSetData($TOKEN_PRIVILEGES,2,$SE_PRIVILEGE_ENABLED,(3 * $nTokenIndex))
                    DLLStructSetData($TOKEN_PRIVILEGES,2,0,(3 * $nTokenIndex))
                DLLStructSetData($TOKEN_PRIVILEGES,2,DllStructGetData($LUID,1),(3 * ($nTokenIndex-1)) + 1)
                DLLStructSetData($TOKEN_PRIVILEGES,2,DllStructGetData($LUID,2),(3 * ($nTokenIndex-1)) + 2)
            $nTokenIndex += 1
        $ret = DLLCall("advapi32.dll","int","AdjustTokenPrivileges","hwnd",$hToken,"int",0,   _
                "ptr",DllStructGetPtr($TOKEN_PRIVILEGES),"int",DllStructGetSize($NEWTOKEN_PRIVILEGES),   _
        $f = DLLCall("kernel32.dll","int","GetLastError")
    If $SP_auxret[0] = 0 Then Return 0
    $SP_auxret = DLLCall("kernel32.dll","int","CloseHandle","hwnd",$hToken)
    If Not $ret[0] And Not $SP_auxret[0] Then Return 0
    return $ret[0]
EndFunc  ;==>SetPrivilege

Remember it works fine with notepad, it doesnt work at all with the game im using until i grant my program permissions using an external program.

p.s i did read that autoit runs in usermode? maybe this is the problem :S

Not at home at the moment, but doesn't require an extra t?

SetPrivilege("SetDebugPrivilege", 1)

I can check my source when I'm home.

EDIT: nope the correct term is "Sedebugprivilege" no T

Either the section in nomadmemory.au3 is incorrect or it doesnt function properly.

Can you compare your source with mine and tell me if im using an outdated version or something?
