Uos are custom visual objects that you can BUILD to supplement standard PB objects. UOs can request/display information and respond to mouse or keyboard actions and create a tab page UO.

Visual UO – a reusable control/set of controls. For example a set of buttons to function as a unit having scripts associated with them for standard processing.

THREE types are:

1. Standard – inherited from a specific visual control. For example command button/checkbox etc.
2. Custom - inherited from the user OBJECT system class. You can include many controls in the UO and write scripts for these EVENTS.
3. External - it is a UO that displays a visual control defined in a DLL.

Class UO – they consist of properties, FUNCTIONS, and events with no visual components.

1. Standard – inherited from a NV PB object such as a transaction/error object, which can have instance variables and functions.
2. Custom – an object of your own design for which you define variables, events and functions in order to encapsulate application-specific programming in an object.
