[The Win32 Location API is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. Instead, use the Windows.Devices.Geolocation API. ]

Sets the default location.

Syntax

HRESULT SetReport(
  [in] REFIID          reportType,
  [in] ILocationReport *pLocationReport
);

Parameters

[in] reportType

REFIID that represents the interface ID of the type of report that is passed using pLocationReport.

[in] pLocationReport

Pointer to the ILocationReport instance that contains the location report from the default location provider.

Return value

Possible values include, but are not limited to, those in the following table.

Return value	Description
S_OK	The location report was successfully set.
E_INVALIDARG	The location report contains invalid data. This may occur when a civic address report does not contain a valid IS0 3166 two-letter country or region code, or when a latitude/longitude report does not contain a latitude between -90 and 90 or does not contain a longitude between -180 and 180.
E_ACCESSDENIED	The user does not have permission to set the default location.

Remarks

ILocationReport is the base interface of specific location report types. The actual interface you use for pLocationReport must match the type you specify through reportType.

Note that the type specified by reportType must be the IID of either ICivicAddressReport or ILatLongReport.

The latitude and longitude provided in a latitude/longitude report must correspond to a location on the globe. Otherwise this method returns an HRESULT error value.

Note An application does not receive the expected location change event from OnLocationChanged if both of the following conditions are true. First, the application runs as a service, in the context of the LOCALSERVICE, SYSTEM, or NETWORKSERVICE user account. Second, the location change event results from changing the default location, either manually when the user selects Default Location in Control Panel, or programmatically when an application calls IDefaultLocation::SetReport.

Examples

The following example shows how to set the default location using a civic address report.

            // set the civic address fields of the Default Location
            hr = spDefaultLocation->SetReport(IID_ICivicAddressReport, spCivicAddressReport);
            if (E_INVALIDARG == hr)
            {
                wprintf(L"The civic address report has invalid data. ");
                wprintf(L"Country/region must be a valid ISO-3166 2-letter or 3-letter code.\n");
            }
            else if (E_ACCESSDENIED == hr)
            {
                wprintf(L"Administrator privilege required.\n");
            }
