Accessing COM interface from C or C++ in Windows environment

Question

I'm relatively new to the Component Object Model specification - I have a simple question:

• How can I access a COM interface from a C or C++ application

For instance, accessing Microsoft Excel COM interface to perform basic operations, without user intervention.

Kind regards

I would suggest looking into ATL if you are using C++, and using C++ if using C. It is very easy to use the #import construct to access COM objects in DLLs or EXEs.
