Stop Music Once Playing

问题:

I am trying to get a song to play in the background of Windows, after a little looking I found this:

@echo off
set file=RRLJ.mp3
(  echo Set Sound = CreateObject("WMPlayer.OCX.7"^)
   echo Sound.URL = "%file%"
   echo Sound.Controls.play
   echo do while Sound.currentmedia.duration = 0
   echo wscript.sleep 100
   echo loop
   echo wscript.sleep (int(Sound.currentmedia.duration^)+1^)*1000) >sound.vbs
start /min sound.vbs

This works well for starting the song but I have no way of stopping it from a .bat file. The only way I found to cut it short is to open task manager and close it from the processes.

I have tried:

taskkill /im wscript.exe

But I keep getting something in the window saying: Success: Sent termination sidnal to the process "wscript.exe" with PID 185448 but the music continues to play until I manually end it with task manager

回答1:

I'd use /T switch (Tree kill): terminates the specified process and any child processes which were started by it.

Here is a script to find ProcessID to terminate exactly needed process only using PID:

@ECHO OFF >NUL
for /F "usebackq tokens=*" %%G in (
      `wmic process where "CommandLine like '%%sound.vbs%%' AND Caption like '%%script.exe%%'" get ProcessID/value ^|find /I "="`
    ) do (
        rem echo %%G
        for /F "tokens=2 delims==" %%H in ("%%~G") do echo  taskkill /T /F /PID %%H  
    )

Note taskkill command is echoed merely... Remove echo when debugged.
