Assuming you have no control over the code of the external application, then, I would say no, there is no Tcl function to do it. You would have to check active processes (exec ps -ef) or something like that.

Hi Bob,

Thankyou for your response.

My use of system commads to find out the processes is limited since i am working in Windows NT. I can see the process in Task Manager-> processes, but not aware of any function to access it

thankyou for your time

I'm afraid there isn't much to go on. This was discussed here before: thread287-66260

Rumman,

There is a program called pslist.exe which gives you the NT equivalent of ps -ef
Don't recall the site this came from but google should.

found the site which has pslist.exe

http://www.sysinternals.com/ntw2k/freeware/pslist.shtml

lists some Utilities that can be used to get process information in Windows, for the people who need it
