I had this problem too...I beleive I solved it by commented the line : //#define WINVER 0x0501 in kssample.h. Try it. If it doesn't work set WINVER at 0x0400. I also had the undeclared identifiers. I don't remember very well but I think I had to manually include headers supplying the definitions (Maybe #include <winioctl.h> )....
