EC_STATUS (Compact 2013)
3/26/2014
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.
