This week's questions (actually last week's): More on HTML and add-ins

How are HTML apps and add-ins associated with each other? (Can HTML apps trigger add-ins to be launched?) HTML and add-ins can both be part of the same application, that is each is a different entrypoint of the application. The association takes place at registration time, when both would be registered as one application. An HTML page can start an add-in (on-demand only, not background) by using the NavigateToPage function with the guid for ExtensibilityEntryPoint as the first parameter.

Is there a way for HTML apps and add-ins to exchange information (parameters) and trigger events? (Is it possible for an add-in to be registered as a listener to an event that is fired within an HTML application?) No, there’s no built in way for add-ins and HTML pages to communicate.< Communication between a background add-in and an HTML page could be achieved with an ActiveX/.NET control on the HTML page and then .NET Remoting between the two components.

How do I register a .exe file so it runs from More Programs? The same way you register an add-in, except instead of using the “addin” property on the entrypoint tag, use “run” with the path to the .exe

    Using the Media State Aggregation Service is there any way to track the channel that your TV tuner card is using if you have dual tuners?

    Specifically, I am writing code to allow me to control a DirecTV receiver using the serial port rather than the unreliable IR blasters. I have working code to change the channels on the receiver, but I have no reliable method to obtain the channel that MCE has assigned each receiver.

    Do you have any idea if the assignment procedures for tuners are documented?
