embedded Python calling app via COM

[Jim]

I have a C++ app which fires up a Python script using C API calls.
That script operates the app via Automation calls, like this:

from win32com.client import *
from mywrapper import *

myapp = Application()
myapp.Visible = True
mydoc = myapp.Documents .Open(...)

My problem is to make sure the instance of myapp is the same one I am
calling from. The above code starts up a new instance of the app,
which is not what I want. In other words I need something like a
GetObject instead of a CreateObject, and I need some way to identify
the calling app so I can tell GetObject about it.

Before I go and do something hack, I thought I'd see if anyone else is
in this situation and knows a good way to do the job.

Pythoncom.GetAc tiveObject will retrieve the running instance of the app.
(assuming that it registers itself in the Running Object Table)

Thanks Roger, that does seem to do the trick. I haven't tested to see
what happens if there are two instances of the app running, I'm hoping
it will return the frontmost visible one.
