Response Event
Fires after a DNS query.
Syntax
type TResponseEvent = procedure Response(Sender: TObject; RequestId: Integer; const Domain: String; StatusCode: Integer; const Description: String; Authoritative: Boolean) of object;
property OnResponse: TResponseEvent read FOnResponse write FOnResponse;
Remarks
The Response event will fire after a call to Query. The RequestId parameter contains the request id associated with the original query. Domain is the domain of the query. The Authoritative parameter is true if the response is from an authoritative name server. If there is an error returned by the server, StatusCode and Description provide them.
Once the query is complete, a single Response event will fire, and the following properties will contain the results:
| StatusCode | The success or error code of the DNS query. |
| Status | A standard string interpretation of StatusCode. |
| Records | The Records in the last DNS response. |
| RecordSource | The source (type) of records being listed. |
