The first keyword is Dim and the second keyword is As.įor example, if you want to declare a variable that acts as a value for a number then you would write the following line of code. You use two keywords to declare a variable. To declare a variable in Visual Basic you have to assign it a data type and give it a name. The first thing is to declare it, then assign it, and finally use it. There are three things you have to do in order to use a variable in your program. In all programming languages, variables are a key component. Variables: Declaring, Assigning, and Using Them Check out Udemy’s course on Programming for Non-Programmers. This could be a way to set the speed of a car in order to calculations or the speed of a vehicle in a game or any other various applications you can think of applying this parameter.Īlthough it can seem complicated, programming is actually rather simple once you get the hang of it. Simply broken down you start off with Vehicle, and within that vehicle section you would pick speed and within the speed section you would set a value of 120. For example, if you wanted to say that the maximum speed of a vehicle was 120, then you would write something along the lines of = 120. You will also have to write in a specific manner when you’re programming in visual basic in order for a computer to understand what you’re saying. These elements include things such as statements, declarations, keywords, operators, and methods. Visual Basic, like many other programs, has programming elements that you will learn to use in order to “speak” the programming language. Many programmers who develop for Windows use Visual Basic since it helps to streamline the programming process. Visual basic is an interesting computer programming language due to the simplicity that it has. The Udemy course Visual Basic for Microsoft Access teaches you a lot about visual basic and how to program using it. Today visual basic has evolved into something far more powerful than it was during its early days of design, and it proves to be something that even advanced programmers still use today. It has software tools pre-installed that doesn’t just allow the user to create programs, but in a sense to draw them as well, which is why it’s called visual basic. The main reason why visual basic is so useful is because it automatically does some of the programming for you. Visual basic has become more than just a programming language, and today many people still use it when they’re developing for windows operating systems.
