Duplicating TreeViews

i use 2 TreeViews with the name tvwR(0) and tvwR(1). sometimes they hold a lot of nodes (>40.000) and i don't want to copy them to a new TreeView with For-Next or Do-Loop. This takes to much time. With the load-command i can duplicate the whole structure of an treeview in some seconds and all the functions and events of the tvwR(0) and tvwR(1) works with the new ones in tvwR(2) and tvwR(3). the load-command works fine to copy tvwR(0) to tvwR(2), but i don't know how to duplicate tvwR(1) into tvwR(3) with the load-Command. ## Deliverables Complete source code of all programming work done
