Yeah, I know this seems like a dumb question, its just a one-off hack I need to wrap up a somewhat mundane task so I can move on to something more interesting.
Maybe more info would help: I'm trying to remove some shortcuts from the desktop and I need the user to see it removed right away (so they don't have to press F5).
You can use the SHChangeNotify API.
[System.Runtime.InteropServices.DllImport("Shell32.dll")] private static extern int SHChangeNotify(int eventId, int flags, IntPtr item1, IntPtr item2);
and then call it this way
SHChangeNotify(0x8000000, 0x1000, IntPtr.Zero, IntPtr.Zero);
