/*
SideShow Class demonstration application. This give a reference
for implementing Microsoft SideShow compatible devices in an
embedded environment. SideShow allows for gadget data displayed
on a Vista machine to also be displayed on an externally connected
interactive display. Upon enumeration on a Vista system, this will
appear as a new SideShow device which can have gadgets loaded onto
it.
Note that while the incomming content is buffered in packet struct
form, the data is not actually displayed. It is left to the user to
write sufficient code to read out the packed data for display to a
screen.
Installed gadgets can be accessed through the InstalledApplications
array, with entries that have their InUse flag set being active. As
only the active content is displayed on the device due to memory
constraints, new content can be requested as needed.
