Setting the wallpaper
-
I am using IActiveDesktop:SetWallpaper function to set the wallpaper. My application generates a bitmap, say D:\image.bmp and then this image is set as wallpaper. The problem is when I edit this image.bmp and call set wallpaper again, the new picture is internally set but is not updated on desktop. I mean to display the new edited picture I need to go to properties->Desktop and then ask windows to load image again. Is there any way to programmatically tell windows to reload the wallpaper image. I guess it just assumes that if path is same, then no need to reload the image?

Hey, thanks for the useful link. The link you have given will be helpful to me in many other ways although the problem I had can be solved by passing AD_APPLY_FORCE flag to ApplyChanges function of IActiveDesktop interface. I was using AD_APPLY_ALL but it was not refreshing the desktop.

IActiveDesktop::ApplyChanges( AD_APPLY_ALL ) alone wont do. You need to pass AD_APPLY_FORCE function to refresh the same picture. AD_APPLY_ALL do not include AD_APPLY_FORCE. Thanks for your reply.
