IHWEventHandler interface (shobjidl.h)

  • Άρθρο

Called by AutoPlay to implement the handling of registered media types.

Inheritance

The IHWEventHandler interface inherits from the IUnknown interface. IHWEventHandler also has these types of members:

Methods

The IHWEventHandler interface has these methods.

 
IHWEventHandler::HandleEvent

Handles AutoPlay device events for which there is no content of the type the application is registered to handle.
IHWEventHandler::HandleEventWithContent

Not implemented. (IHWEventHandler.HandleEventWithContent)
IHWEventHandler::Initialize

Initializes an object that contains an implementation of the IHWEventHandler interface.

Remarks

Developers supporting this interface must expose it in a Component Object Model (COM) server.

All applications registered as AutoPlay media handlers must implement this interface. Handlers that implement this interface should return quickly from calls to IHWEventHandler::HandleEvent and IHWEventHandler2::HandleEventWithHWND so they won't block the AutoPlay dialog from closing. Additionally, if a local server must be launched for the creation of this handler, it should not block the CreateInstance call; it should return as soon as possible.
