How to detect PowerPoint 2007 from a C++ addin?

I need to detect if my addin is in PowerPoint 2007 via my C++ addin. The PowerPoint object model exposes Application.Version, which should work, but I do not know enough about how to use this with IDispatch.

Answer 1

Firstly - call IDispatch::GetIDsOfNames and get id for "Version" property. After that call IDispatch::Invoke which will get Version porperty value by id.

Also, you could generate wrappers with #import directive and use more easy methods for get value of this property.
