Programming languages are slightly different in that you generally don't use them to communicate with a human being. You use a programming language, such as VBA, to communicate with a computer.
More particularly, you communicate instructions to the computer. In other words, Visual Basic for Applications is the language that allows you and me to communicate instructions to Excel. In order to be able to automate tasks in Excel and unleash its power, you must learn VBA. However, as you may expect, VBA is different from regular human languages. More generally, the codes you can use to communicate with your computer are slightly different from those you use to communicate with other people.
Imagine you are learning a new human language such as French, Italian or Spanish. One of the subject you need to study is its structure and, quite likely, you come across terms such as nouns, pronouns, verbs, adjectives, and the like. If you hadn't heard those terms before or you're like me and forgot their precise meanings, learning a new language could be quite challenging.
Programming languages are not significantly different and, therefore, in order to learn a language such as Visual Basic for Applications, you need to understand its structure. Since this structure isn't exactly the same as that of human languages, you encounter some special and different terms that you must learn.
Thank you for your feedback!
And this is where this Excel VBA tutorial for beginners comes in to help. In the following sections, I explain to you some of the most important terms that you need to know to learn VBA programming. By the end of this guide, you will understand the basic building blocks of Visual Basic for Applications, which will allow you to learn this programming language and become fluent much faster.
As a side note: you can, to a certain extent, make an analogy between some of the word classes nouns, verbs, adverbs, etc. Excel and Excel consultant Tracy Syrstad, where you can find a concrete example about how the parts of speech of a regular human language are comparable to certain VBA components.

In this particular Excel VBA tutorial for beginners, I use the analogy between VBA components and parts of speech to a certain extent but, where appropriate, I use different illustrations. Excel macros and Visual Basic for Applications are not exactly the same thing , although they are closely related and, sometimes, people use them interchangeably. A macro is not a programming language. As explained by John Walkenbach one of the most outstanding authors on the topic of Excel in the Excel Bible :. A macro is a sequence of instructions that automates some aspect of Excel.
The whole set of instructions is the equivalent of an Excel macro. It's a sequence of instructions that should be followed in order to achieve a purpose which, in this case, is enjoying a tsukemen meal. The language in which the instructions in the image above are written is English.

This is the equivalent of Visual Basic for Applications. So… as you can see: VBA and Excel macros have a very close relationship but, strictly speaking, they are not the same. However, as you will see below, it is not uncommon to use certain terms interchangeably with the word macro. The following is a very basic example of VBA code. The comments near the top in green font explain what the piece of code does.
I don't go into too may details it deviates from the purpose of this Excel VBA tutorial for beginners but, if you are interested, you can check out this discussion about the difference between macro code and VBA code in Mr. Excel's forum. For purposes of this guide, there is no essential difference. Some very prominent Excel professionals and authors do make a distinction between code and macros. Now that the definitions of macros, VBA and VBA code are clear or at least clearer than they were at the beginning , let's start looking at the different components of Visual Basic for Applications.
In broad terms, a module is the equivalent of a VBA container. In other words, it is where Excel actually stores the VBA code. If you have seen a cargo ship or port, or if you have ever been involved in shipping, you may have seen intermodal containers such as the ones in the image below. These containers are used for, among other purposes, storing goods. In Excel, the equivalent of the intermodal containers are modules and the goods that are stored are the pieces of VBA code.
You can check out which modules are stored in the Excel workbook you're currently working on in the Project Explorer which is one of the sections of the Visual Basic Editor.

There are other types of modules in addition to standard modules but I'll cover this topic in future tutorials. Note however that, as explained by Chip Pearson , standard modules are also referred to simply as modules. A procedure is, basically, the part of a computer program that performs a particular task or action.
In more technical terms, a procedure is a block of statements that is enclosed by a particular declaration statement and an End declaration. Sub procedures do not return a value but function procedures can perform certain activities before returning a value. As explained by Walkenbach in Excel VBA Programming for Dummies , the use of terms such as sub procedure, routine, program, procedure and macro can be a little bit confusing and, generally, they're used interchangeably.
Perhaps the most important distinction you should be able to make is between Sub and Function procedures, as explained above. You can refer to these tutorials on Sub procedures and Function procedures for further information.. I imagine that you may have several questions related to the more technical definition of procedure given above, so let's take a look at the meaning of one of its key words….
A statement is an instruction. In some contexts, you can distinguish 2 main types of statements :. You may wonder, what is the object of those tasks? In other words, on what is Excel performing the particular action? The answer is objects. So let's change topics for a second and focus on English grammar.

Actually, since I used to be a real big fan of horses when I was a child, I use them for explanation purposes throughout this Excel VBA tutorial for beginners and have some more horse pictures throughout this guide. In Visual Basic for Applications things are not very different.

According to Walkenbach, there are more than classes of objects that can be manipulated using Visual Basic for Applications. As explained by Chandoo probably the most prominent Excel blogger here , the ActiveCell and Selection objects which I highlight above are among the most common. As I mention above, classes define objects and, more particularly, classes define the following aspects of an object:.
As a consequence of the above, you can think of objects as instances of classes or, similarly, you can think about classes as blueprints. For example, let's assume you used to run a company that produced roll film cameras. That company had a basic blueprint or technical drawing such as the following:. This blueprint defines the characteristics of each of the roll film cameras to be produced and is, therefore, the equivalent of a VBA class.
Once the company has the blueprint, it can produce the actual cameras. Classes are a slightly advanced Excel topic and, therefore, you're unlikely to work much with them at the beginning. But, just in case, now you know what a class is and how it is different from, and related to, an object. At the basic level, the general use of the word collection doesn't differ too much from the use given to it in VBA. As you'd expect, in very general terms, a collection is a group of objects, more precisely a group of related objects.
At a basic level, the concept of collections is relatively simple I will cover more complicated collection topics in future tutorials but, if you want a more graphical illustration, check out the following Dr. Seuss collection. As explained by John Walkenbach in Excel Power Programming with VBA , collections themselves are objects , although there is also a collection class. Containment relationships are present when objects are put within a container object.
- Lifes A Witch;
- Search results.
- Ein kalter Tag im Paradies – DuMonts Digitale Kriminal-Bibliothek: Alex-McKnight-Serie (Folge 1) (German Edition).
This means that objects can contain other objects within them, such as the plastic container an object that holds the Dr. Seuss books other objects in the image above. Another important type of relationship is hierarchical, which is mostly applicable to classes. Hierarchical relationships occur when a class is derived from a more fundamental class.
Objects have properties. These are the attributes, characteristics or qualities that can be used to describe the object. I cover the topic of properties in this Excel tutorial.
