Code Example: Create and Configure Azure Maps Information Providers

The following code example implements a procedure that accepts an Azure Maps account key, and creates and configures all Azure Maps information provider components:

Delphi
C++

delphi

uses
  dxAzureMapInformationProviders; // Declares all Azure Maps information provider classes
// ...

procedure TMyForm.CreateAzureMapsInformationProviders(const AAzureKey: string);
var
  AProviders: TdxMapControlInformationProviders;
  AProvider: TdxMapControlAzureMapInformationProvider;
  I: Integer;
begin
  AProviders := dxMapControl1.InformationProviders;
  AProviders.BeginUpdate; // Initiates the following batch change
  try
    // Create all Azure Maps information providers
    AProviders.Add(TdxMapControlAzureMapGeocodeProvider);
    AProviders.Add(TdxMapControlAzureMapGeolocationProvider);
    AProviders.Add(TdxMapControlAzureMapReverseGeocodeProvider);
    AProviders.Add(TdxMapControlAzureMapRouteProvider);
    for I := 0 to AProviders.Count - 1 do // Iterates through all created information providers
    begin
      AProvider := AProviders.Items[I] as TdxMapControlAzureMapInformationProvider;
      AProvider.AzureKey := AAzureKey; // Assigns the same Azure Maps account key to all providers
    end;
  finally
    AProviders.EndUpdate; // Calls EndUpdate regardless of the batch operation's success
  end;
end;
