Hourglass in WPF

Hourglass-WPF.cs

private void Button_Click(object sender, RoutedEventArgs e)
{
    // Change the cursor to an hourglass
    Mouse.OverrideCursor = Cursors.Wait;

    try
    {
        // Perform the long-running operation here
        // ...

    }
    finally
    {
        // Always ensure the cursor is reset even if an error occurs
        Mouse.OverrideCursor = null;
    }
}

If you want to show an hourglass cursor only over the specific control (like a button), you can use the `Cursor` property of the control:

```csharp
private void Button_Click(object sender, RoutedEventArgs e)
{
    var button = (Button)sender;

    // Change the cursor of the button to an hourglass
    button.Cursor = Cursors.Wait;

    try
    {
        // Perform the long-running operation here
        // ...

    }
    finally
    {
        // Always ensure the cursor is reset even if an error occurs
        button.Cursor = null;
    }
}
```

This code changes the cursor to an hourglass only when the mouse is over the button¹.

Please note that if your long-running operation is running on the UI thread, the UI will become unresponsive and the hourglass cursor might not show up until the operation is complete. To avoid this, consider running the long-running operation on a separate thread or using async/await¹.
