구문
‘선언
Public Event FlushFailure As SqlCeFlushFailureEventHandler
‘사용 방법
Dim instance As SqlCeConnection
Dim handler As SqlCeFlushFailureEventHandler
AddHandler instance.FlushFailure, handler
public event SqlCeFlushFailureEventHandler FlushFailure
public:
event SqlCeFlushFailureEventHandler^ FlushFailure {
void add (SqlCeFlushFailureEventHandler^ value);
void remove (SqlCeFlushFailureEventHandler^ value);
}
member FlushFailure : IEvent<SqlCeFlushFailureEventHandler,
SqlCeFlushFailureEventArgs>
JScript는 이벤트 사용을 지원하지만 새로운 이벤트 선언은 지원하지 않습니다.
예
다음 예제에서는 FlushFailure 이벤트를 사용하는 방법을 보여 줍니다.
Public Sub Snippet4()
Dim conn As SqlCeConnection = Nothing
Try
conn = New SqlCeConnection("Data Source = MyDatabase.sdf; Password ='<pwd>'")
AddHandler conn.FlushFailure, AddressOf conn_FlushFailure
conn.Open()
'Flush failure occurs here
'OnFlushFailure will be called from the background thread.
Finally
conn.Close()
End Try
End Sub
Private Sub conn_FlushFailure(ByVal sender As System.Object, ByVal e As SqlCeFlushFailureEventArgs)
Dim errors As SqlCeErrorCollection = e.Errors
Console.WriteLine("Flush Failure: " + errors(0).Message)
End Sub
