I've got a collection of pictures that I use for the wallpaper on a windows desktop. It is set to move through the collection randomly at 30 minute intervals.
Occasionally I would like to change the wallpaper (as if the 30 minute interval had elapsed) at that instant. I can go to the desktop, right click then in the context menu select 'Next esktop background'. Now I sometimes find that a bit of work and would like to have an app/bat file on the desktop that would perform the same action.
What command / windows API is required to perform the same action as that context menu command ?
