So the difference between import and include is that:
import = used for binary library like DLL or .Lib files. it's very
similar to include that it load all the header (function definition)
from the DLL file so that we can use the header file just like include
include = just include header (source file)

#import "c:\Program Files\Common Files\System\ADO\msado15.dll" \
rename("EOF", "EndOfFile")
