[python-win32] Re: Getting path+executable associated with a process

[Gabriel Reis]

Hi again,

thanks for the tips. I didn't use EnumProcessModules, but I got the
solution as shown below:

import win32api, win32con, win32process

def IsRunning(filename):
    processes = win32process.EnumProcesses()    # get PID list
    for pid in processes:
        try:
            handle = win32api.OpenProcess(win32con.PROCESS_ALL_ACCESS,
False, pid)
            exe = win32process.GetModuleFileNameEx(handle, 0)
            if exe.lower() == filename.lower():
                return True
        except:
            pass
    return False


This function gets a 'filename' (full path to the executable file) 
and compares it to each process' executable name. It is very useful to
determine wheter a program is running or not.
E.g.: IsRunning('C:\\Program Files\\Mozilla Firefox\\firefox.exe')
should return True, if Firefox browser is opened.

Thanks again,
