Currentmedia. getiteminfo (const string );	Obtain the current media information "title" = media title, "author" = artist, "Copyright" = copyright information, "Description" = media content description, "duration" = duration (seconds), "filesize" = file size, "filetype" = file type, "sourceurl" = original address
Currentmedia. setiteminfo (const string );	Set media information by attribute name
Currentmedia. Name: string;	Same as currentmedia. getiteminfo ("title ")
[Currentplaylist]	WMP. currentplaylist // attributes of the current playlist
Currentplaylist. Count: integer;	Number of media contained in the current playlist
Currentplaylist. item [integer];	Obtains or sets the media information of a specified project. Its Attributes are the same as those of WMP. currentmedia.
