问题 I found this function on the internet: [DllImport("kernel32.dll")] public static extern bool ReadProcessMemory(IntPtr hProcess, int lpBaseAddress, byte[] buffer, int size, int lpNumberOfBytesRead); public static int ReadAddress(string Process_Name, string Address_Offsets) { Process[] P; if ((P = Process.GetProcessesByName(Process_Name)).Length == 0) return -1; int Addy = -1; while (Address_Offsets.Contains(" ")) Address_Offsets = Address_Offsets.Replace(" ", " "); int Index = -1; while (

StackWalk of other process in delphi?

问题 Do you know how to read another process stack in delphi ?? 回答1: Yes. You can enumerate threads with Toolhelp functions; get the context with GetThreadContext(); and read the stack memory (i.e. using ESP from the context) with ReadProcessMemory(). The stack grows downwards in memory, so reading memory locations after ESP is going down the stack. 回答2: You could take a look at the "TThreadSampler.MakeStackDump" procedure of the following unit of my sampling profiler: http://code.google.com/p

What's the fastest way to ReadProcessMemory?

问题 I'm trying to search for all instances of a null-terminated string the memory of a process. I enumed all the alloced memory areas with VirtualQueryEx, then I read them with ReadProcessMemory to a byte array and search using this algo (which I found here and the author claims to be the fastest) public static unsafe List<long> IndexesOf(byte[] Haystack, byte[] Needle) { List<long> Indexes = new List<long>(); fixed (byte* H = Haystack) fixed (byte* N = Needle) { long i = 0; for (byte* hNext = H,

问题 I'm having some trouble with ReadProcessMemory My code is 64 bit I can read the memory of any 32 bit process , but ReadProcessMemory always fails with error code 299 (Partial read) returning 0 bytes read. Done my research and most answers were relate to privilges , but I have Debugging token enabled and running as admin , The address i read the the ImageBase in the PE optional header I tried to check the page status using VirtualQueryEx and got access denied! Note : The code runs perfectly on

ReadProcessMemory fails on some Pages (GetLastError()=299)

谁都会走 提交于 2019-11-30 16:01:39
I try to read all commited pages of a process (Win7-64). On most pages it works but it fails for a few pages. I cannot explain why. Here is my test programme (compiled x32, tested in Win7-64): #include <windows.h> void main() { HANDLE hProc = OpenProcess(PROCESS_VM_READ | PROCESS_QUERY_INFORMATION,FALSE,GetCurrentProcessId()); SYSTEM_INFO si; ZeroMemory(&si,sizeof(SYSTEM_INFO)); GetSystemInfo(&si); char* buf = new char[si.dwPageSize]; for (unsigned i = 0; i < 0x7fff0; i++) { void* baseOffs = (void*) (i * si.dwPageSize); MEMORY_BASIC_INFORMATION mbi; ZeroMemory(&mbi,sizeof(MEMORY_BASIC

问题 im working on a little solitär trainer. I don't know why the function ReadProcessMemory doesn't work. Normally it returns a False or True but in that case nothing. The GetlastError() gives me the Errorcode 6. #-*- coding: cp1252 -*- import ctypes, win32ui, win32process ,win32api PROCESS_ALL_ACCESS = 0x1F0FFF HWND = win32ui.FindWindow(None,"Solitär").GetSafeHwnd() print(HWND) PID = win32process.GetWindowThreadProcessId(HWND)[1] print(PID) PROCESS = win32api.OpenProcess(PROCESS_ALL_ACCESS,0,PID

How to write a Perl, Python, or Ruby program to change the memory of another process on Windows?

落爺英雄遲暮 提交于 2019-11-30 07:16:23
I wonder if Perl, Python, or Ruby can be used to write a program so that it will look for 0x12345678 in the memory of another process (probably the heap, for both data and code data) and then if it is found, change it to 0x00000000? It is something similar to Cheat Engine , which can do something like that on Windows. I initially thought this was not possible but after seeing Brian's comment, I searched CPAN and lo and behold, there is Win32::Process::Memory : C:\> ppm install Win32::Process::Info C:\> ppm install Win32::Process::Memory The module apparently uses the ReadProcessMemory function
