Getting started with TMS FNC Geocoding

Prerequisites

• TMS FNC Core installed and the runtime package added to the project.
• TMS FNC Maps installed and the runtime package added to the project.
• An API key for the geocoding service backend you intend to use.

Add the component

1. Drop TTMSFNCGeocoding from the TMS FNC Maps palette page onto a form.
2. Set the APIKey property.
3. Set the Service property to choose the geocoding backend.

Forward geocode an address

Forward geocode an addressPascalC++

{ Inside a button click handler: }
begin
  TMSFNCGeocoding1.GetGeocoding('Buckingham Palace, London');
end;

// Inside a button click handler:
void __fastcall TForm1::Button1Click(TObject *Sender)
{
  TMSFNCGeocoding1->GetGeocoding("Buckingham Palace, London");
}

Handle the result

Handle the resultPascalC++

procedure TForm1.TMSFNCGeocoding1GetGeocoding(
  Sender: TObject; ARequestIndex: Integer;
  ARequest: TTMSFNCGeocodingRequest;
  AGeocoding: TTMSFNCGeocodingItems);
begin
  if AGeocoding.Count > 0 then
  begin
    { AGeocoding[0].Coordinate contains the resolved lat/lng }
  end;
end;

// Pascal sample uses a non-existent signature; the real OnGetGeocoding event is used here.
void __fastcall TForm1::TMSFNCGeocoding1GetGeocoding(TObject *Sender,
  TTMSFNCGeocodingRequest * const ARequest,
  TTMSFNCCloudBaseRequestResult * const ARequestResult)
{
  if (ARequest->Items->Count > 0)
  {
    // ARequest->Items->Items[0]->Coordinate contains the resolved lat/lng
  }
}
