How to: Create a New Variable - Visual Basic (original) (raw)

• Declare the variable in a Dim statement.

Dim newCustomer  

• Include specifications for the variable's characteristics, such as Private, Static, Shadows, or WithEvents. For more information, see Declared Element Characteristics.

Public Static newCustomer  

You do not need the Dim keyword if you use other keywords in the declaration.

• Follow the specifications with the variable's name, which must follow Visual Basic rules and conventions. For more information, see Declared Element Names.

Public Static newCustomer  

• Follow the name with the As clause to specify the variable's data type.

Public Static newCustomer As Customer  

If you do not specify the data type, it uses the default: Object.

• Follow the As clause with an equal sign (=) and follow the equal sign with the variable's initial value.
  Visual Basic assigns the specified value to the variable every time it runs the Dim statement. If you do not specify an initial value, Visual Basic assigns the default initial value for the variable's data type when it first enters the code that contains the Dim statement.
  If the variable is a reference type, you can create an instance of its class by including the New Operator keyword in the As clause. If you do not use New, the initial value of the variable is Nothing.
