Matlab fails when using Microsoft SDK

I created a simple DLL to try and interface Matlab, and it finally worked fine after fixing a typographical error I originally had with it.

Then I tried to make use of a DLL that isn't so simple (has a lot of functions) and I get a LOT of errors related to the Microsoft SDK that I downloaded following a link from the Matlab website. Below is an example of just one of the errors but there are 50 or more very similar. Anyone have any suggestions what I can do about this:

Function pointer types are unsupported in structures

HRESULT ( __stdcall * QueryInterface )( ICreateErrorInfo * .
