The Mapping element is used in DOCICON.XML to map particular document types to their respective icons.

  Key = "Text"
  Value = "Text">
</Mapping>

Attributes

Example

The code sample below does the following:

  • For different values of the ProgID <META> tag, it maps ProgIDs to the icons representing the applications. For example, "Excel.Sheet" maps to ichtmxls.gif.
  • It maps file extensions to appropriate icons. For example, "doc" maps to icdoc.gif.
  • If neither of the above causes a match, it provides a default value, icgen.gif, for the mapping.
