The StateChange event is called by the MSVidCtl object when the state of the Video Control changes.
object_StateChange( PrevState As Long, NewState As Long)
Identifies the previous state of the Video Control.
Identifies the new state of the Video Control.
Possible values for PrevState and NewState are shown in the following table.
|1||The Video Control has not created a filter graph.|
|2||The Video Control is stopped.|
|3||The Video Control is paused.|
|4||The Video Control is playing.|
This event is analogous to the DirectShow EC_COMPLETE event. You will need to implement a separate event handler in your application for each device type.
