cTREEVIEW Class Wrapper v1.0.2 with ADO Code Example
====================================================

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

Original features include: fast clear a treeview; extended Add/Rename/Delete nodes; 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.

If there are any routines that you feel are missing or code/bug-fixes that you wish to contribute, then please let me know and I'll add them in.
