In the next sections we will look at each of these components in more detail.Īn object property allows us to read a value from the object or write a value to the object. ' Prints the worksheet name Debug.Print Sheet1.Name The Application property allows us to reference the application(i.e. It has an Activate event which is triggered when the worksheet is activated. It has an Activate method which we can use to make worksheet active. Let’s take a look at the first three members of the worksheet. For example, the screenshot below shows the first three members of the Worksheet object If you look in the Object Browser(F2) or use Intellisense you will notice different icons beside the members of an object.

Think of how great your code would be if it was full of these type of objects. All you expect is that turning the key will start the car, pressing the accelerator will speed it up and pressing the brake will slow it down and so on. The details of how this happens are hidden from you. This then causes the wheels of your car to turn.Ī nice looking combustion engine | © For example, fuel gets injected, compressed and ignited leading to combustion. When you are driving your car, a lot of complex stuff is happening. Looking at a real-world example can often be a good way to understand concepts. It is not affected in any way by the existing code and in turn it will not affect the existing code. For example, a Collection can be added to any VBA application. It also makes it easier to add items to an application. Building it this way means you can work on one part without affecting other parts of your application. Using objects allows us to build our applications as blocks. All that we need to know is when we use Add it will add the item, Remove will remove the item and Count will give the number of items. We don’t know how it is doing this and we don’t need to know.

When an item is added it must allocate memory, add the item, update the item count and so on. Take the VBA Collection we looked at above. The major benefit of an object is that it hides the implementation details. In the Worksheet object, the main data item is the worksheet and all the procedures perform actions related to the worksheet.Īn object is used to represent real world or computer based items. The procedures such as Add, Remove, Count then act on this data. In the Collection the data is the group of the items it stores. The procedures are used to perform some task related to the data. We can add items, remove items and get the number of items.ĭefinition of a VBA Object: An object is a grouping of data and procedures(i.e. That is, it does more than storing a piece of data. The Collection is an example of an object. The following code shows an example of using a Collection in VBA ' Sub UseCollection()ĬollFruit.Add "Pear" ' Get the number of items in the collection Dim lTotal As Long In VBA we have a Collection which we use to store groups of items. We either put a value in the variable or read a value from the variable. To store a value while our application is running. Dim Score As Long, Price As Double Dim Firstname As String, Startdate As Dateīasic VBA variables have only one purpose. We use these data types when we are creating a variable e.g. In VBA we have basic data types such as string, integers, double and date.
To understand what an object is, we must first look at simple variables. So grab your favourite beverage and take a journey into the fascinating world of VBA objects. However, before you create your own it is vital that you understand exactly what they are and why you need them. In my next post, I will cover creating objects using Class Modules. How objects such as Collections, Workbooks and Worksheets save you much complexity, time and effort. In this post, you will see how VBA makes brilliant use of objects. In fact, they make your life much easier. If you are serious about learning VBA then it is important to understand VBA Objects. ( Note: Website members have access to the full webinar archive.)
