IITOperationStatus Interface Reference
Inheritance diagram for IITOperationStatus:
Detailed Description
Represents the status of an asynchronous add or convert operation.When a track is added using IITLibraryPlaylist::AddFile(), IITLibraryPlaylist::AddFiles(), IITUserPlaylist::AddFile(), or IITUserPlaylist::AddFiles(), the add may not complete immediately if iTunes needs to make a copy of the file.
Similarly, when converting or importing a file or track using IiTunes::ConvertFile(), IiTunes::ConvertFiles(), IiTunes::ConvertTrack() or IiTunes::ConvertTracks(), the conversion will never complete immediately.
These methods return an IITOperationStatus object, which can be polled to determine when the operation is done. This object will also return the collection of newly added or converted tracks.
As of version 1.1 of the iTunes type library, you should use IiTunes::ConvertFile2(), IiTunes::ConvertFiles2(), IiTunes::ConvertTrack2() or IiTunes::ConvertTracks2() instead of the original convert methods. These new methods return an IITConvertOperationStatus object to allow clients to retrieve additional conversion progress information.
