Du kannst "ID" einfach umbennen, es wird via die DispID zugegriffen.
10 = ObjectID
14 = ArticleID
Code:
[id(0x0000000a), propget, helpstring("Object ID"), helpcontext(0x0001a522)]
long ID();
[id(0x0000000e), propput, helpstring("Use user defined distribution article ID which must be unique"), helpcontext(0x0001a526)]
void ID([in] long rhs);
