I am launching a browser from batch file.
START "www.google.com"
I would like to know the PID of this browser window launched.
There can be many browser windows launched on a single machine. I need to find the PID of the process which was launched by my batch file only. I tried with WINDOWTITLE filter. But its not a good idea as titles may change in future. I am using Windows XP/7
Any help would be appreciated. Thanks.
For what it worth (question is more than 2 years old) this code do the trick, just change variable according to default browser exe
set "browser=palemoon.exe"
tasklist /FI "imagename eq %browser%" /NH /FO csv > task-before.txt
start www.google.com
tasklist /FI "imagename eq %browser%" /NH /FO csv > task-after.txt
:: fc /L /LB1 test4-Before.txt test4-After.txt | find /I "%browser%"
for /f "delims=, tokens=2,*" %%A in ('"fc /L /LB1 task-before.txt task-after.txt | find /I "%browser%""') do set pid=%%A
SETLOCAL enabledelayedexpansion
pid=!pid:"=!
ENDLOCAL
echo pid is %pid%
This is just an idea, to get you maybe on the way
there is a command called Tasklist
there is a switch called filter /FI with lets you decide what filter parameters you want to output, f.e PID. Output this to a > 1.TXT
start your proces
recheck the watchlist and output to 2.TXT
Then you would have to get creative. COmpare 1 to 2, maybe remove the processes in 1 from the 2.TXT The remainig PID is what you wanted?
If you have some programming experience, you could create your own console application that accepts command-line parameters and passes them to the Win32 API CreateProcess() function. One of its output values is the spawned process ID, which your app could then return. Then just update your batch file to call your app instead of using START directly.
I'm trying to do the same thing. Though there must be some way of doing it, but all my Googling suggests not.
Check out robvanderwoude.com to see a list of 3rd party tools and examples. Also check out the full list of Sysinternal's process utilities here.
I've been looking at this for about 2 hours now and I think that there is a way to do this, but it requires some more insight on how windows handles iexplore.exe for PID...
I have a working version of a batch file I wrote that will get you what you want, BUT only if its the FIRST AND ONLY Internet Explorer Window open.
For some reason I can't get the PID to change when I open new browsers, but I can get results if there is no window open (obviously because there is no PID)
Anyhow, this is what I have... you should be able to run this on your system and it will tell you that there are no differences and it might actually produce results if your default browser is Firefox or Chrome or something... just need to make the changes to what I'm providing.

Let me know if this helps...
