data controls;  data-bound controls;  navigation buttons;  Object;  Database

When using the data control DC data binding control in VB to access the database, due to the limitation of its own small number of navigation buttons and single function, it can only browse the database simply, but cannot flexibly insert or delete data. In the development of the actual database application system, the original navigation button can be masked, the new navigation button can be added, and the new program code can be written for the newly added button. The database application system developed by this method has the characteristics of perfect function and simple operation, which can further expand the application range of DC.
