Qs What is Visual Basic?
Ans: 1) Visual Basic is a tool that allows you to develop Windows (Graphic User
Interface - GUI) applications. The applications have a familiar appearance to the user.
2) Visual Basic is event-driven, meaning code remains idle until called upon to
respond to some event (button pressing, menu selection, ...).
3) Visual Basic is governed by an event processor. Nothing happens until an event is detected.
Once an event is detected, the code corresponding to that event (event procedure) is executed. Program control is then returned to the event processor.
