Collections (Visual C++ Syntax Index with #import)
It is useful to know that collections inherit certain common methods and properties.
All collections inherit the Count property and Refresh method, and all collections add the Item property. The Errors collection adds the Clear method. The Parameters collection inherits the Append and Delete methods, while the Fields collection adds the Append, Delete, and Update methods.
