IMbnVendorSpecificEvents interface


Starting in Windows 10, version 1803, the Win32 APIs described in this section are replaced by the Windows Runtime APIs in the Windows.Networking.Connectivity namespace.

This notification interface signals an application of the completion status of vendor-specific operations and other vendor-specific changes in the device state.


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


The IMbnVendorSpecificEvents interface has these methods.

Method Description
IMbnVendorSpecificEvents::OnEventNotification Notification method signaling a change event from the underlying Mobile Broadband device miniport driver.
IMbnVendorSpecificEvents::OnSetVendorSpecificComplete Notification method indicating that a vendor-specific operation has completed.


The following procedure describes how to register for notifications.

  1. Get an IConnectionPointContainer interface by calling QueryInterface on an IMbnInterfaceManager object.
  2. Call FindConnectionPoint on the returned interface and pass IID_IMbnVendorSpecificEvents to riid.
  3. Call Advise on the returned connection point and pass a pointer to an IUnknown interface on an object that implements IMbnVendorSpecificEvents to pUnk.
Notifications can be terminated by calling Unadvise on the connection point returned in step 2.

To view some code that registers for COM notifications, see the Client section of the COM Connection Points article.
