The data type in VBA tells the computer the type of variable that the user intends to use. Different types of variables occupy a varied amount of space in the memory, and users should know how much space the variable will occupy in the computer memory beforehand. A data type specifies the...
First let’s start with a simple example of using a variable: 1 2 Dim myVar As Integer myVar = 10 So what is a variable? Is it basically a symbolic name for a storage location, for storing data or pointers to data. Without variables you would be able to process any data. When usi...
Different types of variable scope that help the users to determine which parts of the code the variable can be used were discussed. We learned the usage of Static variables that helps to retain the value of the variable and Constant variables that help to maintain the value of the variable u...
If you have multiple variables of the same data type, you can declare these on the same line. In the code below, the two String variable types are declared on the same line. Sub VariableExamples() Dim companyID, companyName as String Dim numberOfProducts as Integer Dim productPrice as Do...

Guide to VBA Type. Here we learn how to construct a Type statement in VBA to define variables along with practical examples and a downloadable template.
All variables become Variant data types if not explicitly declared as some other data type. 我以前一直好奇为什么能有什么数据都可以保存的类型,现在对内存知识有了一定了解才知道,其实说到底,Variant底层也是一种数据结构,16个字节分别会有不同的意义,对于一些VBA里的对象复制给Variant后,也只是保存了它的地址...
