static void OnEvent(object sender, MonitorEventArgs e) { if (e.TracePoint==MonitorTracePoint.BeforeEvent) { Console.WriteLine("Description: " + e.Description); Console.WriteLine(" Extra info: " + e.ExtraInfo); } } [MTAThread] static void Main(string[] args) { ZohoDeskConnection ZohoDeskConn = new ZohoDeskConnection( Refresh Token=1000.a6fde76542bfbb5244a7e539d4390e72.87e34ea57023c2d0e7dcb9ce55e3e7f); ZohoDeskMonitor ZohoDeskMonitor = new ZohoDeskMonitor(); ZohoDeskMonitor.TraceEvent += new MonitorEventHandler(OnEvent); ZohoDeskMonitor.IsActive = true; ZohoDeskCommand ZohoDeskCommand = new ZohoDeskCommand("select count(*) from Accounts",ZohoDeskConn); ZohoDeskConn.Open(); Console.WriteLine(ZohoDeskCommand.ExecuteScalar()); ZohoDeskConn.Close(); ZohoDeskMonitor.TraceEvent -= new MonitorEventHandler(OnEvent); Console.ReadLine(); }
Sub OnEvent(ByVal sender As Object, ByVal e As MonitorEventArgs) If e.TracePoint = MonitorTracePoint.BeforeEvent Then Console.WriteLine("Description: " & e.Description) Console.WriteLine(" Extra info: " & e.ExtraInfo) End If End Sub <MTAThread()> _ Sub Main() Dim ZohoDeskConn As ZohoDeskConnection = New ZohoDeskConnection( _ Refresh Token=1000.a6fde76542bfbb5244a7e539d4390e72.87e34ea57023c2d0e7dcb9ce55e3e7f) Dim ZohoDeskMonitor As ZohoDeskMonitor = New ZohoDeskMonitor AddHandler ZohoDeskMonitor.TraceEvent, AddressOf OnEvent ZohoDeskMonitor.IsActive = True Dim ZohoDeskCommand As ZohoDeskCommand = New ZohoDeskCommand("select count(*) from Accounts", ZohoDeskConn) ZohoDeskConn.Open() Console.WriteLine(ZohoDeskCommand.ExecuteScalar()) ZohoDeskConn.Close() RemoveHandler ZohoDeskMonitor.TraceEvent, AddressOf OnEvent Console.ReadLine() End Sub
