Basic Visual Basic Programming Tutorial

How does visual basic programming work? There are many different ways to begin learning how to code, but one of the best places to start is with visual basic programming (VBP). It’s extremely easy to learn and you can use it to create software that runs on Windows-based systems. If you’re new to VBP, this guide will get you started with your first few projects in no time!

Basic Visual Basic

A computer program is just a series of instructions for a computer to execute. As basic visual basic programming languages are relatively easy to learn, you can start working on simple programs within an hour or two. And since most programming languages use these basics, learning basic visual basic programming concepts will serve you well when it comes time to tackle other coding languages.

Basic visual basic programming languages can be used to create applications for Windows, Mac and Linux, as well as web apps that work in any browser. There are also advanced versions of basic visual basic programming languages, such as C#, C++ and Java. These might take more time to master but they provide you with more flexibility than the basic version. The choice between which language to learn depends on your goal: If you want to get started quickly and produce something functional, go with the basics. But if you want more control over your application’s performance, choose one of the more advanced versions.

When it comes to basic visual basic programming, there are a few different steps involved in producing a functioning application. First, you’ll need to come up with an idea for your program. Next, you’ll create flowcharts that map out how different events will trigger actions in your application. This is known as procedural programming because it describes what happens as each event occurs procedurally.

Sub Procedures

One of the most fundamental programming concepts to learn is how to use sub procedures. A Sub procedure is a function that allows you to separate your code into logical segments. For example, let’s say you are writing an application that asks users for their age and then prints out whether they are over 18 or not. You could create two procedures, one that asks for their age and another that checks if they are over 18 or not . You would then call them using a command like Sub AgeCheck() or Sub GetAge().

This basic visual basic programming tutorial will teach you how to use sub procedures. First, you will learn how to create a procedure using in-line code or creating it as a seperate function using Public Sub and End Sub. You’ll then learn how to call your new sub procedures by writing commands like AgeCheck() or GetAge(). Finally, you’ll put all of your knowledge together in an example that calls two procedures to ask users for their age and check if they are over 18.

For and Next Loops

These are some of your most basic loops; all they do is execute a number of lines a certain number of times. A for loop is usually used to count something and a next loop to execute some sort of repetitive action like printing out every line in an array. To run through each line in an array, use a For Each loop instead. The following code would print out A B C D on separate lines:

F For x = 1 To 4

N Print Fx Next x

This would work if the string you wanted to print was contained in one variable but what if it was contained in multiple variables?


A function is a subroutine that performs an action in VB. A function allows you to reuse code and simplify your program. For example, you may have several areas of your program that use a print statement to display a message on screen. Instead of creating these same statements multiple times, consider creating one function that performs these actions for all of these places in your program. You would then use that function throughout your code whenever you need it. This makes programs easier to read and saves space by reducing duplicate code.

There are two types of functions in VB: Subroutines and

procedures. The only difference between these is that a subroutine returns a value, while a procedure does not. This doesn’t affect how you use them, however, so you’ll often hear people refer to both as just functions.


If you’re going to be writing any programs that interface with humans, you’ll need to know a little bit about graphics. After all, it’s hard to interact with someone if you can’t draw them a picture. In an effort to make things easier for programmers (particularly those just starting out), many programming languages have basic functionality for creating graphics output. In most cases, these capabilities are only available through a third-party library or API.

Text Strings

In most programming languages, including Visual Basic, a string is an ordered collection of characters. In your programs, you’ll create text strings when you enter text into a label control (which you’ll learn about in Chapter 9) or when you use any of your program’s features that display textual data to your users. You can also create text strings with VBScript functions such as Len and Mid.

In VBScript, you can use either single or double quotation marks to define a text string. For example, in a MessageBox function call such as MessageBox(Tutorial Successful!), Tutorial Successful! is defined as a text string that includes one comma and two exclamation points. If you use double quotation marks around a text string, you can also embed VBScript variables in your strings.

If and Select Case Statements

One of my favorite features in VB is conditional logic, or as it’s called in other languages, conditionals. Conditional logic allows you to run different sections of code depending on a set of circumstances that you specify ahead of time. These types of statements are where I begin when designing control structures and functions for any program I’m writing. My first step is to consider which type of statement will do the job best: If or Select Case?

The biggest difference between these two statements is that an If statement executes one and only one line of code. When you use a Select Case statement, it will evaluate each possible condition for true, starting with Case number 0 and continuing until a match is found or no more cases exist.

They are also different when deciding which type of conditional logic to use in your program. In general, you can use if-then statements in situations where you want to execute a specific line of code if a certain condition is met.

Random Number Generation

All programs need to generate random numbers for various reasons. Whether you’re simulating a die roll or generating a random password, knowing how to generate secure and reliable random numbers is essential. One of your options is to use the Random class in .NET, which gives you two methods: Next(Int32) and Next(Int32, Int32).

The first returns an integer between 0 and its second argument; if it’s negative, it instead returns 0. It’s also possible to provide a third parameter that specifies the maximum value that can be returned by this method (inclusive). For example, next(-10, 10, 100) will return integers from -10 up to 100. You can also make your own function with similar behavior using Rnd(), which generates double-precision floating point values that are uniformly distributed on . If you’re not sure what this means, take some time to learn about probability distributions!
