Drag and drop items

[The Palm Tree Magician]

I've been running through some Win32 GUI tutorials, and I've hit a brick wall. I want to add a drag and drop item; one that you can drag from a list of available items to a list of chosen items (as in if you had options A, B and C, you could drag A then B then A then C to the list, which would contain A,B,A,C). Google has been thoroughly unhelpful, as the only results deal with dragging text or files into an application, which has little to do with what I want to do.
AKA 'drag and drop item', not 'dragging and droping items to the application'.
I'm not asking for someone to program this for me, but rather for pointers as to what to look for or, if there is such a control item, what it's actually called.
Cheers.

You must use OLE to achieve this. Read here for examples:

Isn't COM stuff funny ?

Thankyou, this is almost exactly what I was looking for, and I'm confident I can tweak it to work for me.
