_Way_ back in the day, I built a PocketPC HTML editor. It used a plain textbox control. Meanwhile, a lot of people were building apps and had expressed interest in having some kind of a rich text edit control, similar to the RichEdit control available as part of the desktop Win32 API. Microsoft's PocketWord app used a rich text control, but it wasn't actually part of the mobile Win32 API, or documented at all. After finding a couple hints on what WndProc messages the control would respond to, I spent a few weeks reverse-engineering it, and wrote up my findings here: https://groups.google.com/d/msg/microsoft.public.dotnet.framework.compactframework/MOk776gh5Fs/9VUDZhFJTokJ https://groups.google.com/d/msg/microsoft.public.dotnet.fram... . I never did wind up building anything useful with that information, but it was a pretty fun exercise.
