My issue is really with the TreeView and the HitTest() method.

After you provided my with the logic for PixelsToTwips, I been testing my drag-n-drop. If you can picture this, Windows Explorer has the same interface that I am trying to implement in my app. I highlight items in the ListView and drag them to a TreeView Node(all I need to know is what node the use dropped on), however, if the node that I drop my items is not the one currently expanded, HitTest() returns the TreeView's Root Node object.

As far as you know is there anything else that I need to do in the TreeView OLEDragDrop Method other than what I've alreay tried

TreeView.OLEDragDrop Method
---------------------------
LPARAMETERS data, effect, button, shift, x, y

*-- Pixels to Twips
m.lnXTwips = 0
m.lnYTwips = 0
THISFORM.PixelsToTwips( @lnXTwips, @lnYTwips )

*-- TreeView node user dropped on
THIS.DropHighLight = THIS.HitTest( x * m.lnXTwips, y * m.lnYTwips )

*-- At this point I would perform my operation

Thanks
