Type is a statement in VBA which is used to define variables similar to the DIM function, it used at the user-defined level where we have one or more values in a variable, there are two nomenclature for type statement which is public or private however these are optional to use, but the variable name and the element name are required.
What is Type Statement in Excel VBA?
VBA Type Statement is used to define variables under one single group name with different data types assigned to each variable. This helps us to group together multiple variables under a single object to use them under the defined type name.
By declaring the Type statement, we can avoid using Class modules in VBAClass Modules In VBAUsers have the ability to construct their own VBA Objects in VBA Class Modules. The objects created in this module can be used in any VBA project.. It doesn’t need any string modules because it can be embedded into already existing modules, which can save us space.
In one of the earlier articles, we have discussed the “VBA ENUMVBA ENUMENUM or enumerations are pre-defined enumerations by users in every programming language. In VBA Vbnewline is an enumeration and we can make our own enumerations using ENUM statement.” to group together all the variables under the single group name.
For example, if you have a group name called “Mobiles,” we have group members like “Redmi, Oppo, Vivo, Samsung, LG and etc..” So Enum statement we can group together with their respective values.
Redmi = 12000
Oppo = 18000
Vivo = 18000
Samsung = 25000
LG = 15000
Like this, we have created enumerations in that article. The problem with the Enum statement as it can hold only a LONG data type. In order to group together variables with different data types, we can use “VBA TYPE Statement.” In this article, we will show you how to construct a Type statement in VBA. Read on…
Before you declare variables by using Type statement, take a look at the syntax:
Type Group Name [Variable 1] as Variable Data Type [Variable 2] as Variable Data Type [Variable 3] as Variable Data Type [Variable 4] as Variable Data Type [Variable 5] as Variable Data Type End Type
These types of statements can be declared within the module as well as at the top of the module, like our Global Variables in VBA.
VBA Type can hold object variables. It can hold arrays. However, it cannot contain procedures, functions.
Type Statement Example in VBA
Ok, let start the process of declaring variables with the Type statement. We will see the same example of declaring Mobile brands like how we have used in VBA Enum.
Step 1: At the top of the module, start the word “Type” and give a name to the Type of group.
Type MobileBrands End Type
Step 2: In Mobile Brands, what are the things we usually see. We see Name first so declare the variable as Name as String.
Type MobileBrands Name As String End Type
Step 3: After the name, we check the Launch date. Declare the variable as LaunchDate as Date.
Type MobileBrands Name As String LaunchDate As Date End Type
Step 4: The next thing is we check Storage capacity. To declare the variable as Storage as Integer.
Type MobileBrands Name As String LaunchDate As Date Storage As Integer End Type
Step 5: The next thing is we check RAM capacity.
Type MobileBrands Name As String LaunchDate As Date Storage As RAM As Integer End Type
Step 6: At last, we check about the Price.
Type MobileBrands Name As String LaunchDate As Date Storage As Integer RAM As Integer Price As Long End Type
Now in the Sub Procedure by declaring the variable as Type, Name, i.e., MobileBrands, we can access all these variable data types.
Step 7: Create a subprocedure.
Sub Type_Example1() End Sub
Step 8: Now declare the variable “Mobile” as MobileBrnads.
Sub Type_Example1() Dim Mobile As Mob End Sub
Step 9: Now, with the variable name “Mobile,” we can access all the variables of “MobileBrands.”
Step 10: Now store each value like the below.
Type MobileBrands Name As String LaunchDate As Date Storage As Integer RAM As Integer Price As Long End Type Sub Type_Example1() Dim Mobile As MobileBrands Mobile.Name = "Redmi" Mobile.LaunchDate = "10-Jan-2019" Mobile.Storage = 62 Mobile.RAM = 6 Mobile.Price = 16500 MsgBox Mobile.Name & vbNewLine & Mobile.LaunchDate & vbNewLine & _ Mobile.Storage & vbNewLine & Mobile.RAM & vbNewLine & Mobile.Price End Sub
Finally, show the result in a VBA message boxVBA Message BoxVBA MsgBox function is an output function which displays the generalized message provided by the developer. This statement has no arguments and the personalized messages in this function are written under the double quotes while for the values the variable reference is provided. like the below one.
Sub Type_Example1() Dim Mobile As MobileBrands Mobile.Name = "Redmi" Mobile.LaunchDate = "10-Jan-2019" Mobile.Storage = 62 Mobile.RAM = 6 Mobile.Price = 16500 MsgBox Mobile.Name & vbNewLine & Mobile.LaunchDate & vbNewLine & _ Mobile.Storage & vbNewLine & Mobile.RAM & vbNewLine & Mobile.Price End Sub
Now run the code using the F5 key or manually and see the result in a message box.
Like this, we can use the “VBA Type” statement to define new data types in the subprocedure.
VBA Types vs. VBA Class
VBA Type is often compared to VBA Class modules. There are certain differences between them. Below are the common differences.
- Difference 1: VBA Type can contain only Public variablesOnly Public VariablesIn VBA, "public variables" are variables that are declared to be used publicly for all macros written in the same module as well as macros written in different modules. As a result, variables declared at the start of any macro are referred to as "Public Variables" or "Global Variables.". VBA Class can contain both Public as well as Private variables.
- Difference 2: VBA Type cannot contain Procedures and Function. VBA Class contains both of them along with properties.
- Difference 3: VBA Type can be declared in any of the modules and procedures. VBA ClassVBA ClassVBA Class allows us to create our Object function to add any features, command line, function type. When created, they act like totally an independent object function but are connected. can only be declared in dedicated class modules.
