ltmmConvert_Notify Constants

typedef enum _ltmmConvert_Notify 
{ 
   ltmmConvert_Notify_Started, 
   ltmmConvert_Notify_Complete, 
   ltmmConvert_Notify_ErrorAbort, 
   ltmmConvert_Notify_UserAbort, 
   ltmmConvert_Notify_Progress, 
   ltmmConvert_Notify_MediaEvent 
} ltmmConvert_Notify;

The ltmmConvert_Notify constants define the WPARAM parameter used in notification messages.

Constant	Description
ltmmConvert_Notify_Started	[0] Indicates that conversion process has started.
ltmmConvert_Notify_Complete	[1] Indicates a successful completion of the conversion process.
ltmmConvert_Notify_ErrorAbort	[2] Indicates a conversion error has occurred. The message LPARAM value contains the HRESULT error code.
ltmmConvert_Notify_UserAbort	[3] Indicates that user has aborted the conversion process by calling StopConvert.
ltmmConvert_Notify_Progress	[4] Indicates the current progress of the conversion process. The message LPARAM value contains the percentage complete.
ltmmConvert_Notify_MediaEvent	[5] Indicates an event related to the current media and the operations performed on it. The message LPARAM value is a pointer to an ltmmMediaEvent structure. For a list of all possible values of the event code and parameters, refer to the ltmmMediaEventCode Constants. Most of these events are DVD-specific, but Windows Media Script notifications and graph-building notifications for MPEG-2 Transport files or UDP streams can also be handled with this event. See ltmmMediaEventCode Constants for more information.
