Issue
Is there a way to trigger a shuffle in windows wallpaper slideshow?
Preferably something I can use from .net
EDIT: so I’m trying to use the IActiveDesktop interface, I got it from here, I tried to use it like this:
public static IActiveDesktop GetActiveDesktop()
{
Type typeActiveDesktop = Type.GetTypeFromCLSID(new Guid("{75048700-EF1F-11D0-9888-006097DEACF9}"));
return (IActiveDesktop) Activator.CreateInstance(typeActiveDesktop);
}
and then calling it like this:
IActiveDesktop dt = GetActiveDesktop();
dt.ApplyChanges(AD_APPLY.ALL | AD_APPLY.FORCE | AD_APPLY.BUFFERED_REFRESH);
nothing happens when I run the code, no errors too.
Solution
Try the following:
Your theme located in C:\Users\USERNAME\AppData\Local\Microsoft\Windows\Themes\.theme
Open the .theme file and update a Shuffle flag in the [Slideshow] section:
[Slideshow]
Shuffle=1
Then use IActiveDesktop interface to reload theme, call ApplyChange with the following parameters:
AD_APPLY_ALL | AD_APPLY_FORCE | AD_APPLY_BUFFERED_REFRESH
