Replicating object selection frame behavior

I'm looking at adding some functionality to a tool that lays out graphical objects on a view.  I would like to mimic the selection behavior of other commercial applications that highlight selected objects with the hatched frames with points (like PowerPoint, Visio, etc.).  In doing the analysis, I was wondering if anyone else has gone down this path had has some MFC design pattern advise or at least help me avoid any unnecessary pitfalls.  There might even be a good class in a library that does this, but I haven't found it yet.  Suggestions?

Any help is greatly appreciated.... Thanks!

Your best bet would be to go with OLE objects, easy and widely supported. I will make things like creation, selection and layering fairly easy (once you've made the object classes and sub classes anyway)

Huh?  You should use OLE for OLE, not for selection!  And it's often inadequate for more complicated apps--OLE objects always have a rectangular area within their client, and objects you draw aren't always rectangles.

Implementing hatching and rubber-band selections isn't very hard. Look at the paint program from my book for examples on how to do rubber-banding and grab handles.

Thanks for the reference Mike.  It looks like your book is going to be the ticket for retro-fitting this behavior into this application I'm taking over.  From some reviews I just read, it looks like you have several other ideas I can play off of as well to beef it up.
