求大神帮助，如何实现自动检测某程序已关闭，如已闭关则自动重新启动程序：GetWindowThreadProcessId(hwnd, &PID);   hProcess=OpenProcess(PROCESS_ALL_ACCESS,false,PID);   if (!hProcess)    return;      else   {    plvitem=(LVITEM*)VirtualAllocEx(hProcess, NULL, sizeof(LVITEM), MEM_COMMIT, PAGE_READWRITE);    pItem=(char*)VirtualAllocEx(hProcess, NULL, 512, MEM_COMMIT, PAGE_READWRITE);
