Outlook treeview/listview control ?

[Erwin van de Wiel]

Does anybody know how to get the same functionality in a listview
the way Microsoft does it when you read newsgroups with outlook.

I looked at it with a windowspy and it was just an ordinary syslistview
control. But I'm intrested in the way it works like a treeview.

It would be a perfect control, a listview and a treeview in one.

Is there anybody who knows the way this works ?

Thanks.
