HRESULT IITUserPlaylist::AddFile (  [in] BSTR  filePath,
[out, retval] IITOperationStatus **  iStatus
) 
 

Add a file or files inside a folder to the playlist.

You cannot use this method to add a file that requires conversion to be added (e.g. a CD track), use IiTunes::ConvertFile() or IiTunes::ConvertFile2() instead. If you add a folder that contains files that require conversion, they will be skipped.

Parameters:
filePath The full path to the file or folder to add.
iStatus Returns an IITOperationStatus object corresponding to the asynchronous operation. If an error occurs, or no files were added, this will be set to NULL.
Return values:
S_OK The operation was successful.
E_POINTER filePath or iStatus is NULL.
E_INVALIDARG filePath is empty or too long, or refers to a file that would require conversion.
ITUNES_E_OBJECTLOCKED This playlist is read-only.
ITUNES_E_OBJECTDELETED This playlist has been deleted.
E_FAIL An unexpected error occurred.

HRESULT IITUserPlaylist::AddFiles (  [in] VARIANT *  filePaths,
[out, retval] IITOperationStatus **  iStatus
) 
 

Add an array of files and/or folders to the playlist.

You cannot use this method to add a file that requires conversion to be added (e.g. a CD track), use IiTunes::ConvertFile() or IiTunes::ConvertFile2() instead. If you add a folder that contains files that require conversion, they will be skipped.

Parameters:
filePaths The single-dimensioned array of full paths to each file or folder. filePaths can be of type VT_ARRAY|VT_VARIANT, where each entry is a VT_BSTR, or VT_ARRAY|VT_BSTR. You can also pass a JScript Array object.
iStatus Returns an IITOperationStatus object corresponding to the asynchronous operation. If an error occurs, or no files were added, this will be set to NULL.
Return values:
S_OK The operation was successful.
E_POINTER filePaths or iStatus is NULL.
E_INVALIDARG filePaths is the wrong VARIANT type, or includes a file that would require conversion.
