A Visual Basic Tutorial for Beginners: Getting Started

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. The Udemy course Visual Basic for Microsoft Access teaches you a lot about visual basic and how to program using it.

Programming in Visual Basic

Visual basic is an interesting computer programming language due to the simplicity that it has. Many programmers who develop for Windows use Visual Basic since it helps to streamline the programming process.

Visual Basic, like many other programs, has programming elements that you will learn to use in order to “speak” the programming language. These elements include things such as statements, declarations, keywords, operators, and methods.

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. 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

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. 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.

Although it can seem complicated, programming is actually rather simple once you get the hang of it. Check out Udemy’s course on Programming for Non-Programmers .

Variables: Declaring, Assigning, and Using Them

In all programming languages, variables are a key component. There are three things you have to do in order to use a variable in your program. The first thing is to declare it, then assign it, and finally use it.

To declare a variable in Visual Basic you have to assign it a data type and give it a name. You use two keywords to declare a variable. The first keyword is Dim and the second keyword is As.

For 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.

This simple line of code tells your program that number is a variable that can be assigned a number that counts as an integer. Remember that integers can only store whole numbers, but what if you wanted to store a number, such as 16.25 or 17.83, then you would have to use another data type.

This line of code allows you to store numbers that don’t have to be whole numbers. You may be wondering why you shouldn’t just use double for all your numbers since it can take more than just whole numbers. A double takes more space and memory than an integer, so you should only use the appropriate data type for your values.

The final type of variable and data type you want to learn to get the basics of Visual Basic is the string. The string is used when you want to use words in your program.

This line of code above will allow you to set a word as a value. This is great for setting names for a person or a company.

Assigning Variables and Values

Above we mentioned how you can assign a variable to a data type. After you write that initial line of code, you can assign a value to that variable as well.

For example if we were to write:

Then the number variable would now be assigned to 44 and its value will remain that until we change it something else. A lot of times your Visual Basic program will tell you there’s an error if you mistakenly try to assign a value to something without first establishing it as a variable.

A way to avoid this mistake is to streamline this coding and instead of breaking it down into two lines of code you simultaneously create the variable and give it a value.

For example, for the number variable you could write:

All of this is in the same line of code and it does the same thing that the previous two lines of code did before. When you’re programming, and you’re writing several hundred or even thousand lines of code at a time, you will want to do whatever you can to make the process a lot simpler.

Creating Your Own Project

Now that you understand some of the basic concepts of Visual Basic, you can actually go ahead and create your own program. In the program, you will assign variables to various data types, give those data types a value, and then have them appear on the screen. You’ve already covered the basics you need to do this, so now all there’s left to do is to create the project and run it for yourself.

To create a new project, go to Visual Basic and open up the program. Then go to File and select New Project.

Within the new project Dialog box you will see various templates to choose from. For this program you will be using the Windows Forms Application template.

Once you click OK after you name the program, Visual Basic will then create all the files you need for the program to run in the Form Designer window. All you have to do is create your variables and see your program come to life.

Creating Your First Visual Basic Program

Now that you’ve done the setup, all you have to do is go to the correct place to enter in your code.

What you’re going to do is create your variables and make the values display on a popup box. Click on the form and it will open up the Code Editor.

When you open up the Code Editor, you will be in a section called Form1_Load and it will be the place where you give your program instructions on what to do when you start it.

In the code editor you will write the following lines of code.

The code you’ve just written has done a few things, all of which you’ve seen and done before. The code declared three different variables, string, integer, and double. The code then assigned those variables to their data types. Remember you can name your variables whatever you want, and it doesn’t have to be the same name as the data type it’s assigned.

The final three lines of code you have to write are

In these message boxes your program puts in your variables along with their values and when you start the program, you will see them appear in a message box.

Once you’re done you just have to press F5 for the program to run.

Now look at your results. You should see each message box appear with the value of your variable in the box. You can click OK or the small x on the upper-right corner to get rid of the box.

That’s all there is to it, and you’ve successfully created your first Visual Basic program!

Now that you know a little bit about Visual Basic programming, you can see how it can be applied to other professions and hobbies. The Udemy course VBA –Visual Basic and Macros , teaches you how to use Visual Basic to create more dynamic excel spreadsheets.

IntelliSense

One thing you probably noticed is as you were writing your program the computer was prompting you with suggestions of what you should write on some of your lines of code. These suggestions are known as IntelliSense, and it helps you write code a lot faster.

If you’re stuck on a program, IntelliSense may help you figure things out so learn to use it when you can.

Projects You Can Do with Visual Basic

Getting started with Visual Basic programming can be really easy as you saw in the tutorial above. With just a few lines of code, you can have a program give you your name, age, birthday, and even calculate complicated problems.

The Udemy course Learning Game Design: As a Job or Hobby teaches you how you can use programming to create video games.

Excel VBA Tutorial – How to Write Code in a Spreadsheet Using Visual Basic

This is a tutorial about writing code in Excel spreadsheets using Visual Basic for Applications (VBA).

Excel is one of Microsoft’s most popular products. In 2016, the CEO of Microsoft said "Think about a world without Excel. That's just impossible for me.” Well, maybe the world can’t think without Excel.

We’re one big happy family!

In this tutorial, you’ll learn about VBA and how to write code in an Excel spreadsheet using Visual Basic.

Prerequisites

You don’t need any prior programming experience to understand this tutorial. However, you will need:

Learning Objectives

Over the course of this article, you will learn:

Important Concepts

Here are some important concepts that you should be familiar with to fully understand this tutorial.

Objects : Excel is object-oriented, which means everything is an object - the Excel window, the workbook, a sheet, a chart, a cell. VBA allows users to manipulate and perform actions with objects in Excel.

If you don’t have any experience with object-oriented programming and this is a brand new concept, take a second to let that sink in!

Procedures : a procedure is a chunk of VBA code, written in the Visual Basic Editor, that accomplishes a task. Sometimes, this is also referred to as a macro (more on macros below). There are two types of procedures:

Note: you can have functions operating inside of subroutines. You’ll see later.

Macros : If you’ve spent any time learning more advanced Excel functionality, you’ve probably encountered the concept of a “macro.” Excel users can record macros, consisting of user commands/keystrokes/clicks, and play them back at lightning speed to accomplish repetitive tasks. Recorded macros generate VBA code, which you can then examine. It’s actually quite fun to record a simple macro and then look at the VBA code.

Please keep in mind that sometimes it may be easier and faster to record a macro rather than hand-code a VBA procedure.

For example, maybe you work in project management. Once a week, you have to turn a raw exported report from your project management system into a beautifully formatted, clean report for leadership. You need to format the names of the over-budget projects in bold red text. You could record the formatting changes as a macro and run that whenever you need to make the change.

What is VBA?

Visual Basic for Applications is a programming language developed by Microsoft. Each software program in the Microsoft Office suite is bundled with the VBA language at no extra cost. VBA allows Microsoft Office users to create small programs that operate within Microsoft Office software programs.

Think of VBA like a pizza oven within a restaurant. Excel is the restaurant. The kitchen comes with standard commercial appliances, like large refrigerators, stoves, and regular ole’ ovens - those are all of Excel’s standard features.

But what if you want to make wood-fired pizza ? Can’t do that in a standard commercial baking oven. VBA is the pizza oven.

Pizza in a pizza oven

Why use VBA in Excel?

Because wood-fired pizza is the best!

A lot of people spend a lot of time in Excel as a part of their jobs. Time in Excel moves differently, too. Depending on the circumstances, 10 minutes in Excel can feel like eternity if you’re not able to do what you need, or 10 hours can go by very quickly if everything is going great. Which is when you should ask yourself, why on earth am I spending 10 hours in Excel?

Sometimes, those days are inevitable. But if you’re spending 8-10 hours everyday in Excel doing repetitive tasks, repeating a lot of the same processes, trying to clean up after other users of the file, or even updating other files after changes are made to the Excel file, a VBA procedure just might be the solution for you.

You should consider using VBA if you need to:

Getting Set Up to Write VBA in Excel

To write VBA, you’ll need to add the Developer tab to the ribbon, so you’ll see the ribbon like this.

VBA developer tab

To add the Developer tab to the ribbon:

After you show the tab, the Developer tab stays visible, unless you clear the check box or have to reinstall Excel. For more information, see Microsoft help documentation.

Navigate to the Developer Tab, and click the Visual Basic button. A new window will pop up - this is the Visual Basic Editor. For the purposes of this tutorial, you just need to be familiar with the Project Explorer pane and the Property Properties pane.

VBA editor

Excel VBA Examples

First, let’s create a file for us to play around in.

Let’s rock and roll with some easy examples to get you writing code in a spreadsheet using Visual Basic.

Example #1: Display a Message when Users Open the Excel Workbook

In the VBA Editor, select Insert -> New Module

Write this code in the Module window (don’t paste!):

Sub Auto_Open() MsgBox ("Welcome to the XYZ Workbook.") End Sub

Save, close the workbook, and reopen the workbook. This dialog should display.

Welcome to XYZ notebook message example

How is it doing that?

Depending on your familiarity with programming, you may have some guesses. It’s not particularly complex, but there’s quite a lot going on:

In short, this is a simple subroutine that contains a function.

When could I use this?

Maybe you have a very important file that is accessed infrequently (say, once a quarter), but automatically updated daily by another VBA procedure. When it is accessed, it’s by many people in multiple departments, all across the company.

Real World Examples

Example #2: Allow User to Execute another Procedure

Sub UserReportQuery() Dim UserInput As Long Dim Answer As Integer UserInput = vbYesNo Answer = MsgBox("Process the XYZ Report?", UserInput) If Answer = vbYes Then ProcessReport End Sub

Sub ProcessReport() MsgBox ("Thanks for processing the XYZ Report.") End Sub

Save and navigate back to the Developer tab of Excel and select the “Button” option. Click on a cell and assign the UserReportQuery macro to the button.

Now click the button. This message should display:

Process the XYZ report message example

Click “yes” or hit Enter.

Thanks for processing the XYZ report message example

Once again, tada!

Please note that the secondary subroutine, ProcessReport, could be anything . I’ll demonstrate more possibilities in example #3. But first...

This example builds on the previous example and has quite a few new elements. Let’s go over the new stuff:

This could be used in many, many ways. The value and versatility of this functionality is more so defined by what the secondary subroutine does.

For example, maybe you have a file that is used to generate 3 different weekly reports. These reports are formatted in dramatically different ways.

Example #3: Add Numbers to a Range with a For-Next Loop

For loops are very useful if you need to perform repetitive tasks on a specific range of values - arrays or cell ranges. In plain English, a loop says “for each x, do y.”

Sub LoopExample() Dim X As Integer For X = 1 To 100 Range("A" & X).Value = X Next X End Sub

Save and navigate back to the Developer tab of Excel and select the Macros button. Run the LoopExample macro.

This should happen:

For-Next loop results

Etc, until the 100th row.

The For-Next loop is one of the most powerful functionalities of VBA; there are numerous potential use cases. This is a more complex example that would require multiple layers of logic, but it communicates the world of possibilities in For-Next loops.

Maybe you have a list of all products sold at your bakery in Column A, the type of product in Column B (cakes, donuts, or muffins), the cost of ingredients in Column C, and the market average cost of each product type in another sheet.

You need to figure out what should be the retail price of each product. You’re thinking it should be the cost of ingredients plus 20%, but also 1.2% under market average if possible. A For-Next loop would allow you to do this type of calculation.

Now that we’ve talked about pizza and muffins and oh-yeah, how to write VBA code in Excel spreadsheets, let’s do a learning check. See if you can answer these questions.

If you have a fair idea of how to you could answer these questions, then this was successful.

Whether you’re an occasional user or a power user, I hope this tutorial provided useful information about what can be accomplished with just a bit of code in your Excel spreadsheets.
