Importing using #import can be used to instantiate a COM component from its type library that is either embedded inside the DLL or as a separate file (.TLB file).
This method prompts the compiler to create the header files which is automatically included in the generated source codes.
It also create smart pointer for all the exposed interfaces using the _com_ptr_t class. The smart pointers will have a naming convention of xxxPtr where xxx is the name of the exposed interface.

The method of #include is a more basic approach where you use the standard COM APIs like CoCreateInstance to instantiate and use the COM component. You will have to manually create smart pointers if needed.
