Abstract: In VB6, Treeview is often used to represent hierarchical data. Code , Requires a large number of manual encoding; in VB. net, due to the enhancement of the Data Binding function and the enhancement of the language features, it is easy to bind the Treeview and hierarchical data. This article will first create a dbtreeview inherited from the Treeview, then, you can bind the hierarchical data of a u
