x 分钟后终止 vbscript [英] Terminate vbscript after x minutes

问题描述

我正在使用 vbscript 编写脚本，我希望它在 x 分钟后自行终止.

I am working on a script with vbscript, and I would like it to terminate itself after x number of minutes.

我在想一些事情，比如在脚本开始时抓住时间，然后将整个事情保持在一个循环中，直到时间是开始时间后的 x 分钟，但我需要它继续在后台检查，而不是只需等到循环完成即可.

I was thinking something like grabbing the time when the script starts and then keeping the whole thing in a loop until the time is x number of minutes after the start time, but I need it to keep checking in the background, and not just wait until a loop is complete.

我想要一条消息或其他内容来通知用户他们花了太长时间，我可以自己做.

I want a message or something that notifies the user they took too long, which I can do myself.

有没有办法在后台跟踪时间，或者确定它会有点冗长的过程?

Is there any way to keep track of the time in the background, or will it be a bit of a drawn-out process to determine it?

推荐答案

按照 Ekkehard.Horner 可能是您的最佳选择.另一种略有不同的方法可能如下所示:

Re-launching the script with //T:xx as suggested by Ekkehard.Horner is probably your best option. Another, slightly different, approach could look like this:

Const Timeout = 4 'minutes

timedOut = False

If WScript.Arguments.Named.Exists("relaunch") Then
  'your code here
Else
  limit = DateAdd("n", Timeout, Now)
  cmd = "wscript.exe """ & WScript.ScriptFullName & """ /relaunch"
  Set p = CreateObject("WScript.Shell").Exec(cmd)
  Do While p.Status = 0
    If Now < limit Then
      WScript.Sleep 100
    Else
      On Error Resume Next  'to ignore "invalid window handle" errors
      p.Terminate
      On Error Goto 0
      timedOut = True
    End If
  Loop
End If

If timedOut Then WScript.Echo "Script timed out."

您仍然会重新启动脚本，但在这种情况下，是您的脚本杀死了子进程，而不是脚本解释器.

You'd still be re-launching the script, but in this case it's your script killing the child process, not the script interpreter.
