multiple instances of winword.exe

[Linny]

Hi,
I am programming for Automation of MS Word XP, in C++.
My application which runs as a background process is concerned with
getting the active Word document and interacting with it.

But whenever I use CoCreateInstance for getting an object of the
Word.Application, another instance of winword.exe is created apart from
the instance of word which is already active and in focus and
I get a pointer to that applications IDispatch interface rather than
the existing one.

I am not able to understand how to get control of the already existing
word app object. Please help me out.

regards
Linny
