Remarks

This event notification is sent to the application. This notification is used to allow the user interface to indicate that a media file is being opened prior to being processed by DirectShow. Because the file might be on the Internet or some slow device, some opens might take longer. This notification is also sent when the file has been opened.

For information on how to use this event code, see CBaseFilter::NotifyEvent.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
