后台创建进程和杀掉进程

后台创建进程：下面这段代码可以后台创建进程，不需要再用dos命令在cmd.exe界面操作了。

  STARTUPINFO si;
  ZeroMemory(&si, sizeof(si));
  si.cb = sizeof STARTUPINFO;

  PROCESS_INFORMATION pi;

//LPTSTR szCmdline = _tcsdup(TEXT("C:\\notepad.exe D:\\file.txt"));
LPTSTR szCmdline = _tcsdup(str);

BOOL res = CreateProcess(NULL, 
                szCmdline,
                NULL, 
                NULL, 
                NULL, 
                NORMAL_PRIORITY_CLASS|CREATE_NO_WINDOW, 
                NULL, 
                NULL, 
                &si, 
                &pi);

//you code

........


if (TRUE == res) 
{
    CloseHandle(pi.hProcess); 
    CloseHandle(pi.hThread);
    killNodeProcess();
}

 

后台杀掉程序：

void killNodeProcess()
{
    STARTUPINFO  si;  
  ZeroMemory(&si,  sizeof(si));  
  si.cb  =  sizeof  STARTUPINFO;  

  LPTSTR szCmdline = _tcsdup(TEXT("taskkill /f /im node.exe"));
  PROCESS_INFORMATION  pi;
  BOOL res  =  CreateProcess(NULL,  
      szCmdline,
      NULL,  
      NULL,  
      NULL,  
      ABOVE_NORMAL_PRIORITY_CLASS|CREATE_NO_WINDOW,  
      NULL,  
      NULL,  
      &si,  
      &pi);
  

  if (TRUE  ==  res)  
  {
      if (!WaitForSingleObject(pi.hProcess,INFINITE))
      {
          CloseHandle(pi.hProcess);  
          CloseHandle(pi.hThread);
      }

  }
      
}
