  • You want to have the same fade effect as when the wallpaper changes backgrounds automatically? – RCIX Dec 30 '09 at 04:10
  • Good code for changing the wallpaper (but does not address your question about fading) : http://stackoverflow.com/questions/1061678/change-desktop-wallpaper-using-code-in-net/1061682#1061682 – BillW Dec 30 '09 at 05:13
  • @RCIX -not exactly, just want to know if it is possible to do this in c# and how can it be done. – murasaki5 Dec 30 '09 at 06:05

This forum post covers changing the wallpaper with a fade: http://www.neowin.net/forum/topic/1035559-fade-effect-when-changing-wallpaper/

They use IActiveDesktop, includes a link to the wrapper class.

Edit
I've now taken this code, and other code, and have implemented it in an open source project: https://pulse.codeplex.com/SourceControl/changeset/view/72677#1589017

You could:

  • Create a window behind everything else (except the desktop).
  • Paint it with the current wallpaper
  • Change the desktop wallpaper
  • Fade out the window (increases it's transparency over a second or two)

You'll have to figure out how to get the window in front of the desktop, but behind the explorer icons. (I assume it's possible to do that.)
