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