Sidebar Gadgets - getting started made easy
We've got some great New Zealand gadgets up on the Microsoft NZ website now including ones from DigiRama, TrafficWatch, NZ Herald, ASB, and TVNZ (my personal favorite). These are all listed on here.
If you've been thinking about writing a side bar gadget (and you are not the only one) there are a few places you might like to start.
The first place to start is the Gadget Development overview which gives you an introduction to building a sidebar gadget. This will give you an understanding of the basic architecture and minimum requirements for a gadget.
There is also the Sidebar Reference (ignore the mostly blank landing page - look in the table of contents...) that will provide details about events and API calls available to use from inside the sidebar.
