Hi Linn.
>So now I can initiate a drag operation but I can't figure out how to make the other node objects highlight as I drag over them.
You'll need to use VFP 6, since this doesn't work correctly in VFP 5. Set the DropHighlight property of the TreeView to the node the mouse is currently over in the DragOver event of the TreeView. Use HitTest to get the node for the X and Y coordinates passed to DragOver. In DragDrop, set DropHightlight to .NULL.
By the way, are you using the proper twips to pixels factors to convert the X and Y coordinates used by HitTest? If not, download my white paper on ActiveX controls (including the TreeView) from the Technical Papers page of
www.stonefield.com for details. This might be the source of other problems you're running into.
