Key Features Of Event Driven Programming

Event Driven Programming is typically used for most modern day software applications, including word processing. In event driven programming it is important to understand the key features of the programming type,in this case it is Visual Basic Studio, these are

An example of this would be when you want to change the font of writing. This window showed in the image is displayed on the screen, making your writing fully customisable to the users needs.
User interface Events
User interface events are one of the key features that are commonly used in visual studio, an example of this would be if the user was to be making a keyboard, the buttons on the screen would be used to represent a letter. This would make the application interactive.
Event loops
Event loops constantly monitor an application and look out for any events that have been triggered by the user in order to cause an action in visual studio. For example; it would react when it senses the user pressing a key on the keyboard.
Flexibility
Flexibility on visual studio is one of the programmers best friends, it enables the user to make their application or program fully customisable that can be created to suit different functions. It gives the user a large amount of control regarding different triggers and the actions that happen because of them.
Suitability for graphical
