[SOLVED] WinRT WRL ABI collections

WinRT WRL ABI collections

I trying work with WRL and stuck with collections.

I need pass to function additional properties:

ABI::Windows::Devices::Enumeration::IDeviceInformationStatics::FindAllAsyncAqsFilterAndAdditionalProperties(
  /* [in] */ __RPC__in HSTRING aqsFilter,
  /* [in] */ __RPC__in_opt ABI::Windows::Foundation::Collections::IIterable<HSTRING>* additionalProperties, ...)

but IIterable has no methods to fill it, and has no touch with IVector<T> (which has methods for filling, but it abstract interface).

Am I need implement my own vector like there or there exist a simpler way to work with collections? What kind of collections return ABI functions under these interfaces?

Solution

You'll need to implement your own (or reuse the ones from the link you posted).

Note that IIterable does have a single method, "First", that you can implement if you want to do it yourself. Have a look in windows.foundation.collections.h for more details.
