ADO example supporting: Load on demand; Find First/ Next/ Previous; Label Edit; Drag'n'Drop; Node & TreeView context menus; node specific Open/Closed/Drag icons.

** Release 2 **
cTREEVIEW class features: Scroll treeview Up/ Down/ PageUp/ PageDown/ Home/ End using code; Dragging with auto-scrolling (not supported by Microsoft in the TreeView control); NodeFirstViewable; & NodeLastViewable.
ADO Example fixes: Find Next/Previous didn't work if branches already loaded. cTREEVIEW class fixes: correct node drag icon displayed.
cTreeview features include: fast clear a treeview; extended Add/Rename/Delete nodes; copy & move nodes through code &/or Drag'n'Drop including parent nodes onto child nodes (not normally possible!); find node using text and (optionally) key properties; check if a node is a parent of another; checks if a node is a root node; a safe get parent node text; right-click context menu (before/after click event); collapse/expand all nodes; collape/expand all child nodes; enable/disable redraw.
This example shows how to:- work with multiple tables of data and load data on demand. As a bonus, I've included cDB class that encapsulates working with an Access Database using ADO. All code is heavily commented.
