C++读写进程内存

读

#include <iostream>
#include <Windows.h>
using namespace std;

int main(){
    HWND hwnd = FindWindowA("MainWindow", "植物大战僵尸中文版");
    cout << hwnd<<endl;
    DWORD pid, tid;
    tid=GetWindowThreadProcessId(hwnd, &pid);
    cout << pid<<endl;
    HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);
    unsigned int 返回值=0;
    ReadProcessMemory(handle, (LPCVOID)0x401004, &返回值, 4, 0);
    printf("%X", 返回值);
}

写

#include <iostream>
#include <Windows.h>

extern "C" UINT32 __stdcall mycall();

using namespace std;

unsigned int  R4(UINT_PTR 数据地址) {
    HWND hwnd = FindWindowA("MainWindow", "植物大战僵尸中文版");
    DWORD pid, tid;
    tid = GetWindowThreadProcessId(hwnd, &pid);
    HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);
    unsigned int 返回值 = 0;
    ReadProcessMemory(handle, (LPCVOID)数据地址, &返回值, 4, 0);
    CloseHandle(handle);
    return 返回值;
}

int main(){
    cout << mycall() << endl;
    //printf("%X", R4(0x6A9EC0));
    printf("%d", R4(R4(R4(0x6A9EC0) + 0x00000768) + 0x00005560));

    UINT_PTR 阳光地址 = R4(R4(0x6A9EC0) + 0x00000768) + 0x00005560;
    HWND hwnd = FindWindowA("MainWindow", "植物大战僵尸中文版");
    DWORD pid, tid;
    tid = GetWindowThreadProcessId(hwnd, &pid);
    HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);
    int 新阳光值 = 1000;
    WriteProcessMemory(handle, (LPVOID)阳光地址, &新阳光值, 4, NULL);
}
