EC_USERABORT

A user has forced the termination of a requested operation.

Parameters

  • lParam1
    Zero.
  • lParam2
    Zero.

Remarks

This event notification is sent by video renderers to the filter graph manager and the application. This notification signals a closure that the user requested. For example, this notification would be sent if the user closed the video window. After this notification has been sent, no more samples should be accepted until the renderer has gone through a stop transition. No EC_REPAINT notifications should be sent after an EC_USERABORT notification is sent unless the renderer is stopped and reset.

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.
