Windows Mobile 5.0 introduced an API known as the State and Notifications Broker for querying many device settings and raising events when these settings change. This library enables Basic4ppc to use that API. A list of the settings available is in the help file together with a link to the Microsoft online documentation. This library requires WM 5.0 or later and .NET 2.0. For technical reasons this library cannot at the moment be merged so there is no source code included with this initial release as putting the source code in the Libraries folder would raise compilation errors. EDIT :- Source archive added for merging on device compile. See post #5 for how.
