IUserNotification2 interface (shobjidl.h)
Exposes methods that set notification information and then display that notification to the user in a balloon that appears in conjunction with the notification area of the taskbar.
Note IUserNotification2 does not inherit from IUserNotification. IUserNotification2 differs from IUserNotification only in its Show method, which adds an additional parameter for a callback interface to communicate with the notification. Otherwise the two interfaces are identical in form and function. CLSID_UserNotification implements both versions of Show as an overload.
Inheritance
The IUserNotification2 interface inherits from the IUnknown interface. IUserNotification2 also has these types of members:
