Expando ObjectsAug 2, 2001
I’ve seen lots of interest lately in expando objects, e.g. objects that can add methods and properties on the fly. Joe Graf wrote a piece on IDispatchEx in MIND that was pretty interesting. My own implementation of IDispatchEx is available here. It supports expando objects that have no static properties or methods as well as those that do. Check out the DispExTest.js for a demonstration, dispeximpl.h, dynamemlist.h and dynamemlist.cpp for the implementation and MyExpando.h for the usage.
