Get Started Building Windows Vista Gadgets
Alrighty, well I had a couple of opportunities to present on Windows Sidebar Gadgets of recent and as promised I've attached to this posting the working demo and a hands on lab to get you up and running with your own funky Windows Vista Gadget.
There are a couple of useful websites on Gadgets
One of the most useful sites is the Sidebar Gadgets Team blog, they post at https://blogs.msdn.com/sidebar/, you'll find some good discussions, useful samples and a couple of hands on labs.
The main Windows Vista Sidebar developer site is on MSDN at https://msdn.microsoft.com/library/default.asp?url=/library/en-us/sidebar/sidebar/reference/launch.asp
