What is Event driven programming in VB?

Answer 1

Events are the actions that are performed by the user during the applications usage. If a user clicks a mouse button on any object then the Click event occurs. If a user moves the mouse then the mouse move event occurs. By the same way an application can generate Key down event, Key up event, mouse double click event.

Answer 2

Event driven programming provides interactivity with the user because the user has to generate an event before the code is run. This means code that is applicable to certain options, e.g. Buttons, is run in accordance to the user's output.

Answer 3

Event Driven Programming is more or less a buzz word because pretty much all programming is "Event Driven" A program typically sits there and does nothing until a user clicks on something (an event) and tells it what to do.

Answer 4

Event Driven Programming in VB can be achieved in several ways:

1. Timing Event.

2. XOR Boolean Event.

3. Numeric Variableequaling, more-than or less-thana second numeric value

Example:

x=0

Do while x<500

debug.print x

x=x+1

loop

Will invoke a looping function until the value (x) is equal to 500 by increasing the value by 1 and re-querying the value of X.

Answer 5

visual basic is called event driven programming language because it works on events
