title: Create a screensaver preview in Delphi
body: <p>I've created a screen saver in Delphi 10 Lite, using diffrent descriptions about this question, available on the web. Now, the screen saver works well, one thing is missing: a good working preview on the Screen Saver Settings dialog box. How can it be created? I've read this description: <a href="https://stackoverflow.com/questions/903180/how-to-make-a-screen-saver-preview-in-delphi">how to make a screen saver preview in Delphi?</a>
  but I'd like something more specific, maybe with an example. I'm using Windows 7 Ultimate SP1.
  Thanks.</p>
