Example

This example uses the TypeName function to return information about a variable.

' Declare variables.
Dim NullVar, MyType, StrVar As String, IntVar As Integer, CurVar As Currency
Dim ArrayVar (1 To 5) As Integer
NullVar = Null    ' Assign Null value.
MyType = TypeName(StrVar)    ' Returns "String".
MyType = TypeName(IntVar)    ' Returns "Integer".
MyType = TypeName(CurVar)    ' Returns "Currency".
MyType = TypeName(NullVar)    ' Returns "Null".
MyType = TypeName(ArrayVar)    ' Returns "Integer()".
