My code is very slow , how do I get it fast? And I would like to put a scanner on if you have a name in memory save it in a text file .

#include <iostream>
#include <iomanip>
#include <windows.h>
#include <tlhelp32.h>
#include <shlwapi.h>
#include <shlobj.h>
#include <fstream>

#define ReadLimit 100*4096 //6 zeroes - for ReadProcessMemory
#define StaticCacheSize 2*40000


using namespace std;

int main()
{

DWORD address = 0x02C076C8;
char* value = new char[79];
HANDLE hProcess, hProcesses;
MEMORY_BASIC_INFORMATION MBI;
BYTE *Buf, pGlobalBuf;
DWORD ReadAddr, QueryAddr, BytesRead, BufSize;
ofstream meuArquivo;

// OpenProcess
HANDLE phandle = OpenProcess(PROCESS_VM_READ | PROCESS_QUERY_INFORMATION,
0,
28104);
// verifica se o soft está em execução
if (!phandle)
{
cout << "Programa não está em execução!";
}

QueryAddr = 0;
while (1)
{ //Enumerate process memory regions

VirtualQueryEx(phandle, (LPVOID) QueryAddr, &MBI, sizeof(MBI)); //if its bigger than 1 0 000 000 bytes, read only that amount

if (MBI.BaseAddress == 0 && QueryAddr != 0)
{
break;
} //memory regions finished

QueryAddr += (DWORD) MBI.RegionSize;

if (MBI.Protect & PAGE_NOACCESS || MBI.Protect & PAGE_GUARD /*|| MBI.Protect&PAGE_EXECUTE || MBI.Protect&PAGE_EXECUTE_READ || MBI.State&MEM_FREE*/)
{
continue;
}

ReadAddr = 0;

while (MBI.RegionSize > 0)
{

if (ReadAddr != 0)
{
ReadAddr += ReadLimit;
}
else
{
ReadAddr = (DWORD) MBI.BaseAddress;
}

if (MBI.RegionSize > ReadLimit)
{

BufSize = ReadLimit;
MBI.RegionSize -= ReadLimit;
}
else
{
BufSize = MBI.RegionSize;
MBI.RegionSize = 0;
}

BytesRead = 0;
meuArquivo.open("teste.txt", ios::out | ios::ate | ios::in);
ReadProcessMemory(phandle,
(LPVOID) ReadAddr,
&value[0],
100,
&BytesRead);
meuArquivo << value << endl;
cout << value << endl;
meuArquivo.close();
}

}

return 0;
}

You are only reading 100 bytes at a time, it is going to be insanely slow to keep doing over and over again. Read the full regions size of memory then check the return values from ReadProcessMemory to determine if it read the full section successfully. If not, it will either say it failed entirely or that it only read partial memory. If it read partial use the BytesRead value to determine how much is left to read and where to offset the read address from to continue reading etc.

group the reads together in as little reads as possible

VirtualQueryEx tells you the max size of the memory block. Try allocating the memory you need first, and then read it.

Or at least read in blocks of 4096 bytes. That's the smallest amount of memory windows/the system can allocate at a time.

To paulomendes1,

This should help.
