This interesting post is for people that want to make a memory editor...

Your missions, should you choose to accept them:
1. Write a CachedRemoteMemory class that extends RemoteMemory for faster scans.
2. Add a cache for the value that was found on the last scan, enabling scans such as 'incremented'.
3. Understand what is going on... shouldn't be hard for one who has mastered C++ (lol). No comments, since comments are ezmode.
(As noted in the file, largely untested so something is probably broken somewhere... I suppose that's what you get for a 1 hour hack job.)
Here is how to use (part of) it.
Code:
#include
#include
#include "memory.hpp"
void ExampleOne(int i) {
std::list items;
Scanner scanner;
std::cout << "Starting..." << std::endl;
if(scanner.Scan(i, items)) {
do {
std::cout << "Scanning..." << std::endl;
} while(scanner.ScanNext(++i, items) > 1);
if(items.size() == 1) {
std::cout << "Done." << std::endl;
std::cout << "i = " << i << std::endl
<< "&i = " << &i << std::endl;
Address addr = items.front();
std::cout << "addr = " << (int)addr << std::endl
<< "&addr = " << (void *)addr.Value() << std::endl;
std::cout << "Setting addr = " << i + 42 << std::endl;
addr = i + 42;
std::cout << "i = " << i << std::endl;
} else {
std::cout << "Something broke. Go fix it." << std::endl;
}
}
}
bool GreaterThan(int a, int b) {
return a > b;
}
bool LessThan(int a, int b) {
return a < b;
}
void ExampleTwo(int i) {
std::list items;
Scanner scanner;
std::cout << "Starting..." << std::endl;
if(scanner.Scan(i-10, items, GreaterThan)) {
std::cout << items.size() << " items greater than " << i-10 << "." << std::endl;
if(scanner.ScanNext(i+10, items, LessThan)) {
std::cout << items.size() << " items also less than " << i+10 << "." << std::endl;
if(scanner.ScanNext(i-2, items, GreaterThan)) {
std::cout << items.size() << " items also greater than " << i-2 << "." << std::endl;
if(scanner.ScanNext(i+2, items, LessThan)) {
std::cout << items.size() << " items also less than " << i+2 << "." << std::endl;
}
}
}
}
}
void PrintTestHeader(int i) {
std::cout << std::endl << "Test " << i << std::endl << "--------------" << std::endl;
}
int main()
{
// Fast
PrintTestHeader(1);
ExampleOne(3);
// Slow - Will probably crash (bad_alloc) on a big process. You need to store results in a file for such a situation.
PrintTestHeader(2);
ExampleOne(0);
// Same as above.
PrintTestHeader(3);
ExampleTwo(100);
return 0;
}
