Question

我正在使用WMI远程启动交互式进程（refer this）

Const INTERVAL = "n"
Const MINUTES  = 1
strComputer = "machineDomain"
strCommand  = "Notepad.exe"

Set objWMIService = _
    GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set objScheduledJob = objWMIService.Get("Win32_ScheduledJob")

Set objSWbemDateTime = _
    CreateObject("WbemScripting.SWbemDateTime")
objSWbemDateTime.SetVarDate(DateAdd(INTERVAL, _
    MINUTES, Now()))

intReturnValue = objScheduledJob.Create(strCommand, _
    objSWbemDateTime.Value, False, 0, 0, True, intJobID)
WScript.Echo "Job ID: " & intJobID

问题在于上面的代码是任务将安排到下一分钟[意味着当前时间是9:30 am然后它将安排到9:31]，但是我想在当前时间仅5秒后安排任务时间。我修改了以下几行：
来自：

Const INTERVAL = "n"
Const MINUTES  = 1

致：

Const INTERVAL = "s"
Const SECONDS  = 5

但它无法正常工作。我认为问题是当我们呼叫SetVarDate(DateAdd(INTERVAL, _ SECONDS, Now())) SECONDS被添加到当前时间时，如果当前时间是9:30:20 AM，那么预定时间将是9:30:25 AM，但是如果时间当前时间是9 ：30：57 AM然后问题。

请有人帮我解决这个问题吗？

提前致谢。

编辑：
为了调用上面的vbscript代码我正在使用以下代码[^]：

            string remoteMachine = Console.ReadLine();
            string sBatFile = string.Empty;
            if (remoteMachine != string.Empty)
                sBatFile = @"\\" + remoteMachine + "\\admin$\\process.bat";
            else
                Console.WriteLine("Invalid Machine name");

            if (File.Exists(sBatFile))
                File.Delete(sBatFile);

            StreamWriter sw = new StreamWriter(sBatFile);
            string _cmd = "DIR > \\\\" + remoteMachine + "\\admin$\\output.txt";
            Console.Write("Enter the remote Command <eg : Notepad.exe, Dir, Shutdown - r, etc..> : ");
            _cmd = Console.ReadLine();
            if ( _cmd.Trim()==string.Empty )
                Console.WriteLine("No command entered using default command for test :" + _cmd);
            sw.WriteLine(_cmd);
            sw.Close();
            ConnectionOptions connOptions = new ConnectionOptions();
            connOptions.Impersonation = ImpersonationLevel.Impersonate;
            connOptions.EnablePrivileges = true;
            ManagementScope manScope = new ManagementScope(String.Format(@"\\{0}\ROOT\CIMV2", remoteMachine), connOptions);
            manScope.Connect();
            ObjectGetOptions objectGetOptions = new ObjectGetOptions();
            ManagementPath managementPath = new ManagementPath("Win32_Process");
            ManagementClass processClass = new ManagementClass(manScope, managementPath, objectGetOptions);
            ManagementBaseObject inParams = processClass.GetMethodParameters("Create");
            inParams["CommandLine"] = sBatFile;            
            ManagementBaseObject outParams = processClass.InvokeMethod("Create", inParams, null);
            Console.WriteLine("Creation of the process returned: " + outParams["returnValue"]);
            Console.WriteLine("Process ID: " + outParams["processId"]);

它工作正常但经过一些尝试后开始给出例外情况：
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))。

我不确定我是否正确理解你的问题，但听起来当地时间和远程机器上的时间之间存在差异。您可能希望在远程计算机上获得时间，然后使用它而不是“现在”。

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * From Win32_LocalTime")

For Each objItem in colItems
If objItem.Hour > 12 Then
    intHour = objItem.Hour - 12
    strAMPM = "PM"
Else
    intHour = objItem.Hour
    strAMPM = "AM"
End If 
strTime = objItem.Month & "/" & objItem.Day & "/" & objItem.Year & " " _
    & intHour & ":" & objItem.Minute & ":" & objItem.Second & " " & strAMPM
Next

然后你可以做

objSWbemDateTime.SetVarDate(DateAdd(INTERVAL,MINUTES, strTime))
