How to check the Windows setting-Location permission is enabled or not for my Application using win32 C ++

Question

Hi,

How to check the Windows setting-Location permission is enabled or not from a Win32 C++ Application.

I would like to know the win32 API which can get the status about the Location setting, whether it's enabled for the application or not.

This is an example code to do the same thing as I said in comment using a console CppWinRT project.

#include "pch.h"
#include <winrt/Windows.Devices.Geolocation.h>
using namespace winrt;
using namespace Windows::Foundation;
using namespace winrt::Windows::Devices::Geolocation;
int main()
{
	init_apartment();
	Uri uri(L"http://aka.ms/cppwinrt");
	printf("Hello, %ls!\n", uri.AbsoluteUri().c_str());
	// Create geolocator object
	Geolocator geolocator;
	auto operation = geolocator.GetGeopositionAsync();
	switch (operation.wait_for(TimeSpan(50000000)))
	{
	case AsyncStatus::Completed:
		printf("result %d\n", operation.GetResults());
		break;
	case AsyncStatus::Canceled:
		puts("canceled");
		break;
	case AsyncStatus::Error:
	{
		winrt::hresult h = operation.ErrorCode();
		puts("failed");
	}
	break;
	case AsyncStatus::Started:
		puts("still running");
		break;
	}
	// Make the request for the current position
	auto status = geolocator.LocationStatus();
}

Hello @67883078,

You may also use the ILocationPermissions interface to check the location capability. For more information, see Sensor API.

Hi @Xiaopo Yang - MSFT

Thanks for your suggestion.

I have gone through the ILocationPermissions Microsoft documentation, it says this interface gets the location capability of the Windows Store app. I want to try with a win32 C++ application.

I would like to know whether I can use the ILocationPermissions interface in a pure win32 C++ application.

I found another way to check the location status using the WinRT:

param::hstring capabilityName(L"Location");
auto s = Windows::Security::Authorization::AppCapabilityAccess::AppCapability::Create(capabilityName);

Windows::Security::Authorization::AppCapabilityAccess::AppCapabilityAccessStatus ss = s.CheckAccess();
