Hi, Can some one help me with this? I scheduled a task from Win xp "Scheduled tasks". This job is will open a reflection window( an application for unix) and doing some other jobs. I want to run it dailly. Now I am having problem: I can run it at first time it's ok, but I can't close up that window so my scheduled task is in runing status, which blocked my next run. I want to find out a way to kill that window. I can see this application runing from task manager. My question is how can I kiil/ close that window from command line? Please help. Thanks in advance

or something can run this in background?

You'll need to run these two commands: tasklist taskkill You'll see the process using tasklist. A PID will be shown next to the process and by running taskkill you will be able to kill it. (I am assuming that the built-in commands in XP are similar to System Internal's pslist and pskill).

Thanks for your advice Astroraptor. Yes, I could use tasklist and taskkill but the problem is how should I do it. Here is my situation: I am runing an application called reflection. When it runing window shows r2win.exe is runing from my tasklist. when I auto run my script named "test" it will bring another widow up and add another r2win.exe in tasklist ( I have serveral r2win.exe runing-- I don't want to kill then all) So I need to use specific PID to kill the one my "test" created.. How can I tell which PID is from my "test". the PID # seems to be the latest but not the biggest. if I use taskkill /f /im r2win.exe it would kill all of my r2win.exe section BTW, on task manager wiondow I can see it shows my "test" is runing-- buy from task list only shows r2win.exe. Is there anyway I can kill specific PID ( I don't know which PID is belong to my "test") Any help is appreciated.

For /F "tokens=2" %%n in ('tasklist ^| Find "r2win.exe"') Do Set Task=%%n TaskKill %task% Set Task= ---- Assuming that TaskList lists all processes based on launch order as does PSList, this will extract the PID and set the last found PID of r2win.exe as %task% which will then be killed by TaskKill. Careful, using Find, you must use the exact case of the EXE file in question. It should always remain the same however. If that doesn't work, try manually looking at the case of r2win.exe.

Thanks Astroraptor. I got another issue now. I trying to combine my script into batch script like this: ************** echo hello -- start test.r2w -- my script to be run For /F "tokens=2" %%n in ('tasklist ^| Find "r2win.exe"') Do Set Task=%%n TaskKill %task% Set Task= echo hello I am finished ************** The proble is my script couldn't ended so the script is hang there the for... part is not get excuted. May be I'll need to use 2 seperated script? 1 my test.r2w 2 batch one to kill( end) my script? Please help.

Have you run this from the command-line to see if an error is displayed?
