刚刚学内核对象,想写个可以防杀的进程,但其他方法太高级,
本菜鸟不感高攀,想了几天,想到一个很本的办法,不正确的
方还请高手指点一下.
程序运行两个事例,每个实例互相监视另外的实例是否存在,
如果不存在,就运行一个.
代码:
// test_process.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include "tchar.h"
#include "iostream.h"
#include "windows.h"

LPCTSTR lpszMutex1 = _T("mutex1");

        CloseHandle(hMutex1);
        cout << lpszMutex1 << " already exist." << endl;
