Response Event

Fires after a DNS query.

Syntax

typedef void __fastcall (__closure *TipwDNSResponseEvent)(System::TObject* Sender, TipwDNSResponseEventParams *e);

__property TipwDNSResponseEvent OnResponse = {read=FOnResponse, write=FOnResponse};

typedef struct {
     int RequestId;
     String Domain;
     int StatusCode;
     String Description;
     bool Authoritative;
} TipwDNSResponseEventParams;

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.
