This event code allows arbitrary status messages to be passed to the application.
Parameters
- lParam1
Value of type BSTR pointing to a string containing a short status message.
- lParam2
Value of type BSTR pointing to a string containing a long status message.
Remarks
The EC_STATUS event code provides a means for filters to pass general supplementary information to the filter graph manager.
A filter is not required to send EC_STATUS events.
Neither DirectShow nor Windows Media technologies place restrictions on how the two EC_STATUS code parameters can be used.
In a typical scenario, an application would watch for EC_STATUS messages and then display the contents of the message to the user in some user interface element such as the status bar.
For information about how to use this event code, see CBaseFilter::NotifyEvent.
