Syntax HRESULT SHAssocEnumHandlers( LPCWSTR pszExtra, ASSOC_FILTER afFilter, IEnumAssocHandlers **ppEnumHandler ); Parameters pszExtra [in] A pointer to a null-terminated buffer that contains a single file type extension, for instance ".jpg". Only handlers associated with the given extension are enumerated. If this value is NULL, all handlers for all extensions are enumerated. afFilter [in] Specifies the enumeration handler filter applied to the full list of handlers that results from the value given in pszExtra. One of the following values. ASSOC_FILTER_NONE Return all handlers. ASSOC_FILTER_RECOMMENDED Return only recommended handlers. A handler sets its recommended status in the registry when it is installed. An initial status of non-recommended can later be promoted to recommended as a result of user action. ppEnumHandler [out] When this method returns, contains the address of a pointer to an IEnumAssocHandlers object.
