HOWTO: Show the Today or Home screen

I recently answered this question on an MSDN forum: how can I show the Today screen from my application? The answer is actually quite simple:

HWND hWndDesktop = GetDesktopWindow();
SetForegroundWindow((HWND)(((ULONG) hWndDesktop) | 0x01) );

The first line of code retrieves the "desktop" window handle (the Today screen) and in the second you set it to the foreground. Easy.
