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:
Methods
The IUserNotification2 interface has these methods.
| IUserNotification2::PlaySound Plays a sound in conjunction with the notification. (IUserNotification2.PlaySound) |
| IUserNotification2::SetBalloonInfo Sets the information to be displayed in a balloon notification. (IUserNotification2.SetBalloonInfo) |
| IUserNotification2::SetBalloonRetry Specifies the conditions for trying to display user information when the first attempt fails. (IUserNotification2.SetBalloonRetry) |
| IUserNotification2::SetIconInfo Sets the notification area icon associated with specific user information. (IUserNotification2.SetIconInfo) |
| IUserNotification2::Show Displays the user information in a balloon-style tooltip. |
