IWMRegisterCallback::Advise method (wmsdkidl.h)

Article

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The Advise method registers the application to receive status messages from the sink object.

Syntax

HRESULT Advise(
  [in] IWMStatusCallback *pCallback,
  [in] void              *pvContext
);

Parameters

[in] pCallback

Pointer to the application's IWMStatusCallback interface. The application must implement this interface.

[in] pvContext

Generic pointer, for use by the application. This is passed to the application in calls to OnStatus.

Return value

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Remarks

The sink object sends status messages to the application by calling the application's IWMStatusCallback::OnStatus method.

When the application has finished using the sink object, use the Unadvise method to break the connection with the sink object.
