State & Notification Broker 101

  • Artikkeli

Not sure when it was published, but I just stumbled across this excellent article from Don that explains the new managed State & Notification Broker APIs (my baby) and everything you need to know to start taking advantage of them.

    I've actually found that you can use this in native C++ applications too. It's quite nice for monitoring the phone's signal strength.

    Thanks guys/gals!

    Hey Robert,

    I'm been trying to do some testing with this API in the WM5.0 emulator. Specifically with the phoneincomingcall changed event. When I make a call from/to the emulator using the 4250010001 number, the event doesn't seem to fire...I've successfully managed to handle other changed events, such as the call going on and off hold, but not a change in the incoming call status.

    Is this the correct property to be looking at if I want to be notified when there is an incoming call?

    Many thanks

    This feature is awesome when trying to optimize data replication based on the type of network that is available.

    Can this be used to detect if there is a WiFi or a Cell data signal present. My application needs to automatically detect a signal or either the WiFi network or a cellular data network and begin transfering data. Is there an integration of MSMQ-CE and this API such that my app can write to MSMQ-CE and then forget about it? Whenver there is a connection MSMQ-CE subsystem will take care of the transfer. Thanks
