i try to do something like :
GroupwareTypeLibrary.Application4Class gac = new GroupwareTypeLibrary.Application4Class();
GroupwareTypeLibrary.Account4Class ac = gac.Login("cristinal","","cris",null,null) as GroupwareTypeLibrary.Account4Class;

GroupwareTypeLibrary.FoldersClass fc = (GroupwareTypeLibrary.FoldersClass)ac.AddressBooks;
