Subclassing Samples

Subclassing the .NET Treeview, Listbox and Combobox controls - Here are two completly functional sample Visual Basic .NET projects which demonstrate the rather simple but extremely powerful technique of subclassing the TreeView, ComboBox, or ListBox, such that you can store additional custom information behind (or inside) each individual Tree Node, Listbox Item or Combobox Item as you desire. There is no logical limit to the amount of additional information which can be stored alongside each individual node or item.
