Easy way to tell if a program is running.

I am writing an automatic download process that will update software on a
computer. We've got services that run all of the time and a couple of
programs that run all of the time. How can I tell if the program/service is
running so I can stop it, update it and restart it?

TIA - Jeff.

I guess the easies way would be to try updting (replacing the files) if the
the program/service is running you will get an excpetion that the file you
are trying to replace is locked (used at the moment). Collect all such
failed updates and ask the user to stop problematic applications or if it is
possible stop them by yourself. You can also rename the files that has been
in use (you can do that even if the file is locked in the memory) and copy
the new ones. When the installation is done ask the user to restart the
machine. You need to have a mechanism to delete the old renamed files ones
the system is up and running again.

Other solution would be to use the Process class to check out all running
processes at the moment.

The services are easy to tell, all you have to do is use ServiceControll er
class to tell the status.

Regarding the running programs you could just follow Stoitcho's suggestion ,
or alternatively you could create a unique object in the system and check
for it (a common techinque to assure only one instance of an app is run)

Then you could send a message to the running process for it to terminate

Hi all. Handling files is an extremely frequent task in programming, so most programming languages have an abstraction of the basic files offered by the underlying operating system. This is indeed also true for our language of choice, Python. Its file type allows some extraordinary convenient access like: for line in open("blah"): handle_line(line)
