[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The getAttributeCountByType method retrieves the number of attributes associated with the specified attribute name and language.

Syntax

retVal = Media.getAttributeCountByType(
  name,
  language
)

Parameters

name [in]: String containing the name of the attribute. For information about the attributes supported by Windows Media Player, see the Windows Media Player Attribute Reference.
language [in]: String representing the language. If the value is set to null or "" (empty string), the current locale string is used. Otherwise, the value must be a valid RFC 1766 language string such as "en-us".

Return value

This method returns a Number (long) containing the attribute count.

Remarks

This method is used to determine the number of attributes corresponding to a particular attribute name for a given Media object. Index numbers can then be passed to the getItemInfoByType method. This is useful, for example, when a media item has been categorized under multiple genres.

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

Windows Media Player 10 Mobile: This property always returns 0.
