I think it would be good to have those `Set` member templates, which were added in Windows 8.1 SDK.One of the 'Set' member template has a MSVC macro. I can not figure out any proper alternative of that. I have replaced it with std::is_convertible but got compiler error. Could you add those please? I can try to compile that with gecko.
Do you mean this thing? ``` template <typename T> HRESULT Set(__in_opt const T &strRef, // const-ref required in case caller has a type convertible to const wchar_t*, but not copy-able typename ::Microsoft::WRL::Details::EnableIf< __is_convertible_to(T,const wchar_t*), ::Microsoft::WRL::Details::Dummy>::type = ::Microsoft::WRL::Details::Dummy()) throw()
```
This can be declared as
```
#include <type_traits> // std::enable_if, std::is_convertible
template<typename T>
HRESULT Set(
const T& strRef,
typename std::enable_if<
std::is_convertible<T, const wchar_t*>::value,
::Microsoft::WRL::Details::Dummy>::type
/* no name */ = ::Microsoft::WRL::Details::Dummy())
throw()
```
