TdxAzureMapResponse.ErrorInfo Property

Provides access to detailed error information if the current server query is not successful.

#Declaration

Delphi
property ErrorInfo: TdxAzureMapErrorDetail read;

#Property Value

Type Description
TdxAzureMapErrorDetail

Stores detailed information on an Azure Maps server query.

The property value is nil (in Delphi) or nullptr (in C++Builder) if an Azure Maps server does not return query error information.

#Remarks

Use ErrorInfo and StatusCode properties to obtain detailed error information if the IsSuccess property returns False.

#Code Example: Validate Server Response

The code example in this topic section demonstrates a function that checks if an Azure Maps server response is valid. The function returns False and displays a message box with the corresponding error message if a server query fails.

uses
  dxMessageDialog;  // This unit declares the dxMessageDlg global function
// ...

function TMyForm.ValidateServerResponse(AResponse: TdxAzureMapResponse): Boolean;
begin
  if AResponse <> nil then
  begin
    Result := AResponse.IsSuccess;
    if not Result and Assigned(AResponse.ErrorInfo) then
      dxMessageDlg(AResponse.ErrorInfo.Message, TMsgDlgType.mtError, [mbOK], 0);
  end
  else
    Result := False;
end;
