finding the typedef of unmanaged type in managed c++

Hi,

I'm trying to use the __typeof operator to find the size of
CRYPTPROTECT_PROMPTSTRUCT in managed c++:

DWORD somesize = Marshal::SizeOf(__typeof(CRYPTPROTECT_PROMPTSTRUCT ));

I'm getting a compilor error that __typeof expects a fully defined
managed type. Can someone please tell me another alternative way to
find the typeof the typedef (CRYPTPROTECT_PROMPTSTRUCT is a typedef
defined in wincrypt.h)?

Thanks

Sharon

size_t somesize = sizeof(CRYPTPROTECT_PROMPTSTRUCT);
