Import COM Object in Qt

I'm trying to import a COM Object in a .cpp program by using Qt framework (the COM object is an .exe file). After the inserion of the line "#import "C:VNA\S2VNA\S2VNA.exe" ", function's parameters reported below turns black. Moreover, used object methods seems to be not accessible or different wrt the delared and the #import code line turns green. Thanks in advance Qt #Import
