_MemoryRead problem

[Hatish]

Hi, how i can read this Offset with _MemoryRead?

8B15 F8A66400  MOV EDX,DWORD PTR DS:[64A6F8]

I need to read 64A6F8 Thanks for help!

Ok here is an example

 Spoiler

$pid = ProcessWait("yourprocess.exe")
$openmem = _MemoryOpen($pid)

$myValue=_MemoryRead(0x64A6F8,$openmem)

MsgBox(0,"Hi there","Your value: " & $myvalue)

;					_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
