Attributes That Support Multiple Values (Compact 2013)

3/26/2014

This topic lists attributes that can have multiple values assigned to them.

For example, "Artist" is an attribute that can have multiple values. You can call IWMHeaderInfo3::AddAttribute multiple times to add as many Artist values as you want. If you make multiple calls to AddAttribute for attributes that do not support multiple values, the method might return an error code, or it might ignore your request.

Some attributes can have multiple values only in Advanced Systems Format (ASF) files; other attributes can have multiple values in both ASF and MP3 files.

The following table lists the attributes that support multiple values.
