ResPath = TreeSelect(TREE_RecipeTV)

// Selected rows in a multiselection memory TreeView control
FOR i = 1 _TO_ TreeSelectOccurrence(TREE_TREEVIEW1)
Trace("Selected element: " + TreeSelect(TREE_TREEVIEW1, False, i))
END

// Equivalent to:
// i is int
// FOR EACH SELECTED ROW i OF TREE_TREEVIEW1
// Trace("Selected element: " + TreeSelect(TREE_TREEVIEW1, False, i-1))
// END
