Introduction
In Visual Basic for Applications (VBA), constants are used to assign a meaningful name to a value. Once a constant is declared, it cannot be modified or assigned a new value. In this guide, we will walk you through the process of declaring constants and using them in VBA.
Prerequisites
Before you begin, make sure that you have Microsoft Excel installed on your computer. You will also need a basic understanding of programming concepts.
Declaring Constants
To declare a constant in VBA, you need to use the Const statement followed by the constant name and value. Here are some examples:
Const pi As Double = 3.14159
Const daysInWeek As Integer = 7
Const companyName As String = "Microsoft"
In the above example, we have declared three constants: pi, daysInWeek, and companyName. pi is a double-precision floating-point constant that stores the value of pi. daysInWeek is an integer constant that stores the number of days in a week. companyName is a string constant that stores the name of the company.
Data Types
Constants can be declared as one of the following data types: Boolean, Byte, Integer, Long, Currency, Single, Double, Date, String, or Variant. Because you already know the value of a constant, you can specify the data type in a Const statement.
Scope
By default, constants are private to the module in which they are declared. To declare a public constant that can be accessed from other modules, precede the Const statement with the Public keyword.
Conclusion
Understanding constants is essential for anyone looking to assign meaningful names to values in VBA code. By following these steps and declaring constants with appropriate data types for your use case in VBA programming language you will be able to write efficient code!
