Syntax

Parameters

Remarks

This method retrieves the metadata for an individual digital media item or a media item that is part of a playlist.

This method supports attributes with multiple values and attributes with complex values. The getItemInfo method does not support attributes with multiple values and attributes with complex values.

The attributeCount property contains the number of attribute names available for a given Media object. Index numbers can then be used with the getAttributeName method to determine the name of each available attribute. Individual attribute names can be passed to the name parameter of getItemInfoByType.

The getAttributeCountByType method returns the number of attributes that correspond to a particular attribute name for a given Media object. Index numbers can then be passed to the index parameter of getItemInfoByType. This is useful when a digital media item has been categorized under multiple genres, for example.

To use this method, read access to the library is required. For more information, see Library Access.

This method can cause errors. You should include error-handling code when you call this method. For example, in JScript you can implement error handling by using the try...catch...finally structure.

Windows Media Player 10 Mobile: This method is not supported.

Requirements

Version: Windows Media Player 9 Series or later.

Library: Use wmp.dll.
