PowerTCP SSL Sockets for .NET |
| Dart.PowerTCP.SslSockets Namespace : TraceEventArgs Class |
Provides data for the EndSend event which marks the completion of an asynchronous trace route operation.
For a list of all members of this type, see TraceEventArgs members.

Dart.PowerTCP.SslSockets.TraceEventArgs
[Visual Basic]
Public Class TraceEventArgs
Inherits EventArgs[C#]
public class TraceEventArgs : EventArgs[C++]
public __gc class TraceEventArgs : public EventArgs[C++/CLI]
public ref class TraceEventArgs : public EventArgsA TraceEventArgs object is passed as a parameter to all events that mark the completion of an asynchronous trace route operation. The Result property is a TraceResult object encapsulating data about the trace route operation.
If your code causes an exception, it would be returned to the handling event without you seeing it. To preclude such a condition, you should ALWAYS use a try/ catch block around your event-handling code.
The following example demonstrates an asynchronous trace route operation.
[Visual Basic]
Private Sub TraceTest()
' Set all hops and echoes to be synchronous
Trace1.HopType = HopType.SynchHops
' Do not exceed 25 hops
Trace1.MaxHops = 25
' Begin the trace route operation.
Trace1.BeginSend("www.dart.com", Nothing)
End Sub
Private Sub Trace1_Hop(ByVal sender As Object, ByVal e As HopEventArgs) Handles Trace1.Hop
' Display information about the hop
Debug.WriteLine("Time-to-live for the hop: " & e.Result.TTL)
Debug.WriteLine("Remote address: " & e.Result.RemoteAddress)
' Now display info about each of the three echoes
Debug.WriteLine("Response times for this hop")
Dim er As EchoResult
For Each er In e.Result.Echoes
Debug.WriteLine(er.ResponseTime)
Next
Debug.WriteLine("Average time for this hop: " & e.Result.AverageTime)
End Sub
Private Sub Trace1_EndSend(ByVal sender As Object, ByVal e As TraceEventArgs) Handles Trace1.EndSend
' Check for any exceptions
If e.Exception Is Nothing Then
' Trace operation is complete, display info.
Debug.WriteLine("Total hops: " & e.Result.Hops.Length)
Else
Debug.WriteLine("Exception: " & e.Exception.Message)
End If
End Sub
[C#]
private void TraceTest()
{
// Set all hops and echoes to be synchronous
trace1.HopType = HopType.SynchHops;
// Do not exceed 25 hops
trace1.MaxHops = 25;
// Begin the trace route operation.
Trace1.BeginSend("www.dart.com", null);
}
private void trace1_Hop(object sender, HopEventArgs e)
{
// Display information about the hop
Debug.WriteLine("Time-to-live for the hop: " +
e.Result.TTL);
Debug.WriteLine("Remote address: " + e.Result.RemoteAddress);
// Now display info about each of the three echoes
Debug.WriteLine("Response times for this hop");
foreach(EchoResult er in e.Result.Echoes)
Debug.WriteLine(er.ResponseTime);
Debug.WriteLine("Average time for this hop: " + e.Result.AverageTime);
}
private void trace1_EndSend(object
sender, TraceEventArgs e)
{
// Check for any exceptions
if(e.Exception == null)
// Trace operation completed successfully, display info.
Debug.WriteLine("Total hops: " +
e.Result.Hops.Length);
else
Debug.WriteLine("Exception: " +
e.Exception.Message);
