Effectively referencing and utilizing resources from different program parts is critical. This article discusses a common scenario: dynamically changing the NotifyIcon icon based on the program state.

Create resources

Create icon resource:

1. Right-click on the project in Solution Explorer and select Properties.
2. Go to the Resources tab.
3. Click on the first button and select "Icon".
4. Use "Add Resource" to add the desired icons.
5. Double-click the added resource to edit.

Use resources

Use the Properties.Resources static class to access resources. The following code dynamically sets the NotifyIcon icon:

<code class="language-c#">paused = !paused;
if (paused)
    notifyIcon.Icon = Properties.Resources.RedIcon;
else
    notifyIcon.Icon = Properties.Resources.GreenIcon;</code>

This approach simplifies resource access and operations, enabling complex program logic to be implemented efficiently.
