Redraws a specified tree view control item in the style used to indicate the target of a drag-and-drop operation. You can use this macro or the TreeView_Select macro, or you can send the TVM_SELECTITEM message explicitly.
BOOL TreeView_SelectDropTarget(
HWND hwndTV,
HTREEITEM hitem
);
Returns TRUE if successful, or FALSE otherwise.
If the specified item is the child of a collapsed parent item, the parent's list of child items is expanded to reveal the specified item. In this case, the parent window receives the TVN_ITEMEXPANDING and TVN_ITEMEXPANDED notification messages.
Using the TreeView_SelectDropTarget macro is equivalent to sending the TVM_SELECTITEM message with its flag parameter set to the TVGN_DROPHILITE value.
