AspLog Class

Definition

Provides a property and methods for writing event and exception information to the application's log listeners.

public ref class AspLog : Microsoft::VisualBasic::Logging::Log
public class AspLog : Microsoft.VisualBasic.Logging.Log
type AspLog = class
    inherit Log
Public Class AspLog
Inherits Log
Inheritance
AspLog

Examples

This example shows how to use the My.Application.Log.WriteEntry method to log tracing information. For more information, see How to: Write Log Messages.

Public Sub TracingTest(ByVal fileName As String)
    My.Application.Log.WriteEntry( 
        "Entering TracingTest with argument " & 
        fileName & ".")
    ' Code to trace goes here.
    My.Application.Log.WriteEntry( 
        "Exiting TracingTest with argument " & 
        fileName & ".")
End Sub

Remarks

The My.Application.Log object provides a straightforward entry point from which to access the .NET Framework's logging services. The WriteEntry and WriteException methods write messages to the application's log listeners. The listeners can be configured by the application's configuration file. For more information, see Walkthrough: Changing Where My.Application.Log Writes Information and Working with Application Logs.

The My.Application.Log object is available only for client applications. For Web applications, use My.Log. For more information, see Microsoft.VisualBasic.Logging.Log.
