Simple Memory Editor

7 posts in this topic

#1 ·  Posted (edited)

This little bit of code was made because I needed a way to change values in the memory space of a running program on the fly with different values.

and as such I just made my own tool for it with AutoIt and here is the result of that endeavor, any comments on ways to do any of it better welcomed

#cs
Memory_Editor.au3 - It's not fancy and may not be the best way to do it, but it does what I needed it for ;-)
#ce

#Include <NomadMemory.au3>
#include <string.au3>

$i = 1

While $i = 1
    $Do_It = MsgBox(262148, "Do You Wish To Edit A Program's Memory Space ?", _
    "Do You Wish To Continue [Yes / No] ?" & @LF & "Also You Can Enter x At Anytime To Exit")
    If $Do_It = 6 Then _Edit()
    If $Do_It = 7 Then Exit
WEnd

Func _Edit()
$File = InputBox("Process to use", "Enter Process Name From Taskman", "" , " M", 75, 20, -1, -1)
If $File = 'x' Then Exit

$Addy = "0x" & InputBox("Address to use", "Enter Start Address [Hex]", "", " M", 75, 130, -1, -1)
If $Addy = 'x' Then Exit

$Type = InputBox("Data Type", "Enter 1 for Text" & @lf & "Enter 2 for Hex", "", " M", 75, 130, -1, -1)
If $Type = 'x' Then Exit
If $Type = '1' Then
    $Text = InputBox("New Data", "Enter Text String", "", " M", 600, 130, @DesktopWidth/4, -1)
    $Data = "0x" & _StringToHex($Text)
    ElseIf $Type = "2" Then
    $Data = "0x" & InputBox("New Data", "Enter Hex Data", "", " M", 600, 130, @DesktopWidth/4, -1)
    Else
Exit

EndIf

$Proc = ProcessList($File)
    $ID = _MemoryOpen($Proc[1][1])
    If @Error Then
    MsgBox(262144, "ERROR", "Failed to open memory")
    EndIf
    _MemoryWrite($Addy, $ID, $Data, 'byte[' & StringLen($Data)/2-1 & ']')
    _MemoryClose($ID)
    MsgBox(262144,"Confirmed", "Memory Edited")
EndFunc

A good start to a useful script Thamiel.

If you are thinking of developing it I would suggest trying to get one gui to replace all the inputs, have radio buttons for options rather than entering a nuimber, and display the current contents of a memory location with an option to change it. A bit more error checking would be helpful.

BTW, related to crapmail's contribution post, I prefer CODE tags as my signature verifies.


Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
