Diagnosing NS_E_WMPCORE_ITEMNOTINPLAYLIST
This result is HRESULT 0xC00D1086. At the playback core item not in playlist checkpoint it means the requested Media object is not a member of the current Playlist generation; the result belongs to the Windows Media playlist and metafile state machine, not to an unspecified Player failure.
Evidence that separates the result
| Result | Different boundary |
|---|---|
NS_E_WMPCORE_PLAYLISTEMPTY | The current playlist contains zero media items at the point an item is required |
NS_E_WMPCORE_INVALIDPLAYLISTMODE | The playlist manager received a play-mode value it does not implement |
NS_E_WMPCORE_PLAYLIST_EMPTY_OR_SINGLE_MEDIA | The requested playlist operation requires multiple items, but the list has at most one |
Representative case: Code retains an IWMPMedia object after replacing the current playlist. The example isolates only the producing component.
Verification
Repeat the original operation with a fresh owning object after the identified precondition is corrected. Treat this result as resolved only when that same operation passes this stage; preserve any later HRESULT as a separate failure.
