Hello,

This tutorial will focus on the general api's to use to edit memory, which are:

- WriteProcessMemory

We will use the following api's to obtain the necessary parameters for WPM (WriteProcessMemory) which are:

- FindWindow
- GetWindowThreadProcessId
- OpenProcess

To begin, we add a module (Project --> Add Module --> Module --> OK)

In this module, it will contain the functions declarations, we will do it like so:

Public Declare Function GetWindowThreadProcessId Lib "user32" (ByVal hWnd As Long, lpdwProcessId As Long) As Long Public Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long Public Declare Function WriteProcessMemory Lib "kernel32" (ByVal hProcess As Long, ByVal lpBaseAddress As Any, lpBuffer As Any, ByVal nSize As Long, lpNumberOfBytesWritten As Long) As Long Public Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal Classname As String, ByVal WindowName As String) As Long

We will also declare this constant, this will full in for the first parameter for OpenProcess (Desired Access), and is done like so:

Public Const PROCESS_ALL_ACCESS = &H1F0FFF

Now, since we have the declarations for the functions we will use, we will also make our own function called "WriteAInt", when we want to edit memory, we will refer to this function instead of finding the values etc all the time, and editing memory.

This is done like so:

Public Function WriteAInt(ByVal Address As Long, ByVal Value As Long) Dim hWnd As Long Dim ProcessID As Long Dim Handle As Long hWnd = FindWindow(Classname, Windowname) GetWindowThreadProcessId(hWnd, ProcessID) Handle = OpenProcess(PROCESS_ALL_ACCESS, False, ProcessID) Call WriteProcessMemory(Handle, Address, Value, 4&, 0&) Call CloseHandle(Handle)

Now, since we have everything ready, add a button to the form or w/e and do the following:

WriteAInt(AddressInHex, Value)
