When a computer processes information or data, that data should be placed in its memory first, then it performs different operations on that. You application as well should process the information in memory. To accomplish that the you allocate memory by defining variables. Simply, a variable is small piece of memory that allows the program to process data within it.
To define a variable in VB.NET you use the following format:
1 |
Dim MyInt As Integer |
Where the Dim tells the computer that you are going to define a variable. Next you write variable name (in this case it is MyInt) and finally the data type As Integer which tells the computer you are going to perform integer operations on the data in that variables.
