Why vb is called event driven programming

Even if a computer wakes up on a signal from a modem or via a LAN signal it is still the result of an initial user request. Even if that request is an automatically timed request every day at say 2am. This is still at the request of some initial user or programmer. Therefore all events are initiated by a user or programmer , whether those events happen later in an automatic fashion or not is irrelevant. Computers do nothing by themselves and I hope they never do!!

Otherwise one day we may have a Terminator scenario. Mankind can still turn every computer in the world off, if we really wanted to!! I guess it depends on how one defines an event really. You got my meaning s. Turning the computer on in the first place!! As the Doctor in Doctor Who would say it is all; "Cause and effect".

VB is called Event-Driven because it has the capability of responding to events, not because you have to create VB programs using an event-driven model. The description is quite correct because it distinguishes VB from previous versions of BASIC and a number of other programming languages which do not have the ability to respond to events.

Acamar: Going by your definition, then most every computer language that has ever been created up till now is event driven. Every version of BASIC that I have seen, at least gave you the ability to wait for and read keyboard input from the user.

Every CPU, which does not always mean computer chip, that I am familiar with has a means to generate "Interrupts", either through hardware or software. Tuesday, February 16, PM. Acamar: Going by your definition, then most every computer language that has been created up till now is event driven.

Enough said? No one is arguing. I think the term EDP is grossly mis-used. I think it refers more to a style or structure to the code than what the code actually does. The "hows and whys", not the "whats and whens", of how the the code works.

Event - driven programs do not implement algorithms. An event - driven program is written to respond to specified events by executing a block of code or function associated with the event. The order in which an event - driven program will run cannot always be known ahead of time. Gema Cucarella Explainer. What is meant by Object Oriented Programming?

Object - oriented programming OOP refers to a type of computer programming software design in which programmers define the data type of a data structure, and also the types of operations functions that can be applied to the data structure. Jacqueline Koshes Explainer. What is VB language? Anina Reeve Pundit. What do you mean by visual programming? Visual programming is a type of programming language that lets humans describe processes using illustration.

Whereas a typical text-based programming language makes the programmer think like a computer, a visual programming language lets the programmer describe the process in terms that make sense to humans. Badayco Meceta Pundit. What is event driven programming in Java? In Java GUI applications, a user's interaction with a component is called an event. As a programmer, you can write code to do something after these events. This is why Java is referred to as being event driven.

In Java , the general term for an event is the event object. Eulogio Bahamonde Pundit. Disadvantages: Complex, Hard to control, Time consuming to get event loops and event handlers running.

Object driven programming languages are all based around objects on a 'form' or a 'room'. For example the program will be ran around buttons or other controls. For example if a user clicks a button a set of defined steps will occur. Event driven is similar. For example if this occurs then do this. Basically it is more simple for novice programmers to use and get their head around. Boring and unneccesary.

Is visual basic a object oriented programming language? Why visual Basic is called an event driven programming?

Why is VB considered an event driven programming language? Event-driven can make programming easier for some by being able to directly edit the object you want the code for. Another thing that can make the programming easier is that when using an event driven language such as visual basic it usually has predictive coding so when the user is coding it will predict what you want to do from what you are typing.

Both purely procedural and purely imperative approaches get brittle as they grow in length and complexity. It allows for more interactive programs. Almost all modern GUI programs use event-driven programming. It can be implemented using hardware interrupts, which will reduce the power used by the computer.

But it is an Event drive programming, easy to develop applications. Login to your account using email and password provided during registration. Don't have an account? Sign up.
