Answer 2

给你个简单的吧，
PROCESSENTRY32 pe32;
HANDLE hSnaphot;
HANDLE hApp;
DWORD dProcess;
hSnaphot = CreateToolHelp32Snaphot(TH32CS_SNAPPROCESS,0); //获取进程快照
Process32First(hSnaphot, &pe32); //指向第一个进程
do
{
在这里你可以对当前枚举到的进程进行处理，如果是你需要结果的进程，就
HANDLE hProcess=OpenProcess(PROCESS_TERMINATE, FALSE, pe32.th32ProcessID);
if(!hProcess)
TerminateProcess(hProcess); //关闭进程
}
}while(Process32Next(hSnaphot, &pe32)); // 不断循环直到取不到进程
