The event handler receives an argument of type DataEventArgs containing data related to this event. The following DataEventArgs properties provide information specific to this event.

Property	Description
Data	Gets data provided by Data and Log events.
Message	Returns the message argument provided by the Marshal method. (Inherited from Dart.Emulation.UserStateEventArgs)
UserState	Returns the user state argument provided by the Marshal method. (Inherited from Dart.Emulation.UserStateEventArgs)

The handler must be added before connecting. See the SynchronizingObject property for information on updating UI controls in your event handler.

This example demonstrates logging sent and received data to a textbox.

C#

private void myComponent_Log(object sender, DataEventArgs e)
{
    string prompt = (e.Data.Direction == DataDirection.In) ? "Recv: " : "Sent: ";
    textBox1.AppendText(prompt + e.Data.ToString() + Environment.NewLine);
}

Visual Basic

Private Sub myComponent_Log(ByVal sender As Object, ByVal e As DataEventArgs)
    Dim prompt As String = If(e.Data.Direction = DataDirection.In, "Recv: ", "Sent: ")
    textBox1.AppendText(prompt & e.Data.ToString() & Environment.NewLine)
End Sub
