I'm trying to plan out a generic ActiveX control.  It deals with a rather
complicated tree structure and I was wondering how could I pass the data in
the tree structure to the container.  I've heard that you can't simply pass
pointers out of a control, but for me that would be the easiest solution.

Could somebody explain why I can't pass a pointer and also help with some
solutions?

Thanks.

If the ActiveX control will only be used in-process then you can pass pointers in or out by simply casting the pointer to and from any OLE supported type, such as long*.
