# EventLog

The Wisej.NET `EventLog` component enables interaction with Windows event logs, which record important software and hardware events. Use it to read existing logs, write entries, manage event sources, and respond to log entries.

{% hint style="info" %}
The `EventLog` implements `IDisposable`. Always dispose of it either:

* Directly: Call `Dispose()` in a try/catch block
* Indirectly: Use language constructs like `using` (C#) or `Using` (VB)
  {% endhint %}

## Features

### Log Management

Access and manage event logs through static `EventLog` members:

* List available logs
* Create or delete logs
* Create or delete event sources
* Check source existence on a computer

### Default Logs

Windows provides three default event logs:

* Application: General application events
* System: Windows system events
* Security: Security-related events (read-only)

Additional logs may be available from installed applications and services like Active Directory.

{% hint style="info" %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wisej.com/docs/controls/other-components/eventlog.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
