VB Package

These classes are in the VB built-in package, which provides the standard set of controls (CheckBox, CommandButton, ComboBox, Label, TextBox, …) and the form infrastructure that hosts them.

Classes

Non-Controls

• App -- singleton wrapping the running application's identity, version metadata, and process-level state
• Clipboard -- singleton wrapper around the system clipboard for inter-application copy and paste
• Global -- the application's app object -- singleton whose members (App, Screen, Clipboard, Forms, …) are reachable without qualification
• Printer -- drawing-surface wrapper around one Windows printer device, recording graphics calls into a spooled print job
• Printers -- read-only collection of every printer installed on the system
• Screen -- singleton wrapping the primary display's metrics, font list, active form and control, and application-wide mouse pointer
