'Declaración
Public Event FlushFailure As SqlCeFlushFailureEventHandler

public event SqlCeFlushFailureEventHandler FlushFailure

public:
event SqlCeFlushFailureEventHandler^ FlushFailure {
    void add (SqlCeFlushFailureEventHandler^ value);
    void remove (SqlCeFlushFailureEventHandler^ value);
}

    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
