The ltmmConvert_Notify constants define the WPARAM parameter used in notification messages.
typedef enum _ltmmConvert_Notify
{
ltmmConvert_Notify_Started,
ltmmConvert_Notify_Complete,
ltmmConvert_Notify_ErrorAbort,
ltmmConvert_Notify_UserAbort,
ltmmConvert_Notify_Progress,
ltmmConvert_Notify_MediaEvent
} ltmmConvert_Notify;
[0] Indicates that conversion process has started.
[1] Indicates a successful completion of the conversion process.
[2] Indicates a conversion error has occurred. The message LPARAM value contains the HRESULT error code.
[3] Indicates that user has aborted the conversion process by calling StopConvert.
[4] Indicates the current progress of the conversion process. The message LPARAM value contains the percentage complete.
[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.
