  The SiticoneBackgroundWorker class extends the standard BackgroundWorker to
  automatically enable progress reporting and simplify the reporting of custom
  progress messages.

# Worker Initialization and Configuration

## Overview

SiticoneBackgroundWorker is an enhanced implementation of the BackgroundWorker component in .NET WinForms applications. It provides built-in support for progress updates and custom messages, making it easier for developers to manage background operations without additional configuration. The primary enhancement is the ability to report progress along with an accompanying message using the `ProgressChangedEx` event.

### Key Points

<table><thead><tr><th width="312">Feature</th><th>Description</th></tr></thead><tbody><tr><td>Inherits BackgroundWorker</td><td>Extends the standard BackgroundWorker class to provide enhanced functionality.</td></tr><tr><td>Automatic Progress Reporting</td><td><code>WorkerReportsProgress</code> is automatically set to <code>true</code>, eliminating the need for manual configuration.</td></tr><tr><td>Custom Progress Event</td><td>The <code>ProgressChangedEx</code> event supports messages along with progress updates.</td></tr><tr><td>Custom Progress Reporting Method</td><td>The <code>ReportProgressEx(int percentProgress, string message)</code> method allows reporting progress with additional context.</td></tr></tbody></table>

### Best Practices

| Practice                                | Explanation                                                                                                     |
| --------------------------------------- | --------------------------------------------------------------------------------------------------------------- |
| Always subscribe to `ProgressChangedEx` | Since this event includes additional message functionality, developers should prefer it over `ProgressChanged`. |
| Use `ReportProgressEx` for clarity      | This method makes progress reporting more readable and self-explanatory.                                        |
| Keep background work lightweight        | Avoid long-running or blocking operations inside the worker to keep the UI responsive.                          |

### Common Pitfalls

| Issue                                          | Solution                                                                                          |
| ---------------------------------------------- | ------------------------------------------------------------------------------------------------- |
| Forgetting to handle `ProgressChangedEx`       | Ensure you attach an event handler to `ProgressChangedEx` to receive custom progress updates.     |
| Calling `ReportProgressEx` from outside DoWork | This method should only be called from within the worker thread to avoid cross-thread exceptions. |

### Usage Scenarios

#### Scenario 1: Updating a Progress Bar with Custom Messages

A developer wants to execute a long-running task in the background and update a progress bar while displaying status messages.

**Implementation:**

```csharp
using System;
using System.ComponentModel;
using System.Threading;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;

public partial class MainForm : Form
{
    private SiticoneBackgroundWorker _worker;
    private ProgressBar progressBar;
    private Label statusLabel;

    public MainForm()
    {
        InitializeComponent();
        InitializeWorker();
    }

    private void InitializeWorker()
    {
        _worker = new SiticoneBackgroundWorker();
        _worker.ProgressChangedEx += Worker_ProgressChangedEx;
        _worker.DoWork += Worker_DoWork;
    }

    private void Worker_DoWork(object sender, DoWorkEventArgs e)
    {
        for (int i = 0; i <= 100; i += 10)
        {
            Thread.Sleep(500); // Simulate work
            _worker.ReportProgressEx(i, $"Processing {i}% complete");
        }
    }

    private void Worker_ProgressChangedEx(object sender, SiticoneBackgroundWorker.ProgressChangedExEventArgs e)
    {
        progressBar.Value = e.ProgressPercentage;
        statusLabel.Text = e.Message;
    }
}
```

### Real-Life Usage Scenarios

<table><thead><tr><th width="190">Scenario</th><th>Explanation</th></tr></thead><tbody><tr><td>File Processing</td><td>While scanning or processing files, display progress along with the current file name.</td></tr><tr><td>Data Upload</td><td>Show progress percentage along with a status message indicating the upload stage.</td></tr><tr><td>Database Queries</td><td>Report progress as rows are being processed.</td></tr></tbody></table>

### Troubleshooting Tips

| Issue                        | Possible Cause             | Solution                                             |
| ---------------------------- | -------------------------- | ---------------------------------------------------- |
| ProgressChangedEx not firing | Event handler not assigned | Ensure `ProgressChangedEx` has an attached delegate. |
| UI freezing                  | Work done on UI thread     | Ensure long operations are inside `DoWork` method.   |

### Review

### Summary

<table><thead><tr><th width="270">Feature</th><th>Benefit</th></tr></thead><tbody><tr><td>Automatic progress reporting</td><td><code>WorkerReportsProgress = true</code> by default, reducing setup time.</td></tr><tr><td>Custom progress event</td><td><code>ProgressChangedEx</code> supports progress updates with messages.</td></tr><tr><td>Simplified reporting method</td><td><code>ReportProgressEx</code> makes progress updates more intuitive.</td></tr></tbody></table>

By following best practices and using the provided examples, developers can effectively manage long-running tasks while keeping the UI responsive.
