Developer's Guide - Code Samples

In This Topic

This is a collection of the significant code samples available throughout the documentation.

Alerting

Submitting ASP.NET Sessions immediately on Error: This example shows how to set your web site to automatically send data to you via email or a Server whenever there's an error recorded on the site.
Submitting Session data on Error (other than ASP.NET): This example shows how to send session data immediately after an error occurs while the application is still running.
Send Email Message on Error: This example shows how to send a very descriptive email message when errors occur in your application.

Configuration

Configuration through Code: You can configure the Agent through code instead of using an App.Config for most scenarios (the primary exception being ASP.NET where the web.config is highly recommended). This example shows a WinForm application being configured programmatically.
Add the Loupe Trace Listener: A quick way to add just the Loupe Trace listener to your application.

Using Loupe as your Log System: Demonstrates how to log data directly to Loupe both by porting forward code designed to use the .NET Trace capability and new code optimized for the Loupe API.
Relaying log messages from your own logging system: If you already have a central logging class you can gateway calls into Loupe easily.
Log handled exceptions using PostSharp: Demonstrates a PostSharp aspect that logs exceptions after they're thrown when they cause a method to exit.
Trace entry and exit from methods: Demonstrates a PostSharp aspect that records method entry and exit complete with parameter information and results.
Logging Exceptions (Any platform): There are optimized methods for logging unexpected and unhandled exceptions.
Display Exceptions to a user (WinForms and WPF): You can leverage the Loupe Error Manager to present a user-friendly dialog when unexpected exceptions happen in your application.
Logging Unhandled Exceptions in WinForms: If you want to do your own custom unhandled exception handling in WinForms, this walkthrough will get you there.

Defining Event Metrics: Two examples demonstrating event metrics with and without reflection.
Defining Sampled Metrics: Two examples demonstrating sampled metrics with and without reflection.
Profile the performance of a method: Demonstrates a PostSharp aspect that is optimized for profiling a single method.
Record feature utilization using PostSharp: Demonstrates a PostSharp aspect used to record how often a particular method in your application is used, how long it takes to run, and whether it was ultimately successful or not.

A complete walkthrough of designing and implementing an event metric to track the performance of database queries. Go to Developer's Guide - Metrics - Database Query Event Metric Example.

Simple Sending to Email or File: Example using the Packager class to send new sessions to an email address or to a file you specify.
Using the WinForms Packaging Wizard: WinForms example of using the PackagerDialog class to display a user-friendly wizard for sending data via Server, email, or file.
Sending Packages from the Command Line: Examples of using the Packager Utility to create & send sessions with or without user interaction.
Letting Users Opt In to Sending Data: Example of how to use the integrated User Opt In capabilities for WinForms & WPF applications.

Log handled exceptions: Demonstrates a PostSharp aspect that logs exceptions after they're thrown when they cause a method to exit.
Record feature utilization: Demonstrates a PostSharp aspect used to record how often a particular method in your application is used, how long it takes to run, and whether it was ultimately successful or not.
Track the value of a class field: Demonstrates a PostSharp aspect that will record the value of a field as it changes throughout the lifespan of your application.
Profile the performance of a method: Demonstrates a PostSharp aspect that is optimized for profiling a single method.
Trace entry and exit from methods: Demonstrates a PostSharp aspect that records method entry and exit complete with parameter information and results.
