36 * IQueryAssociations {SHLWAPI}
39 * This object provides a layer of abstraction over the system registry in
40 * order to simplify the process of parsing associations between files.
41 * Associations in this context means the registry entries that link (for
42 * example) the extension of a file with its description, list of
43 * applications to open the file with, and actions that can be performed on it
44 * (the shell displays such information in the context menu of explorer
45 * when you right-click on a file).
48 * You can use this object transparently by calling the helper functions
49 * AssocQueryKeyA(), AssocQueryStringA() and AssocQueryStringByKeyA(). These
50 * create an IQueryAssociations object, perform the requested actions
51 * and then dispose of the object. Alternatively, you can create an instance
52 * of the object using AssocCreate() and call the following methods on it:
