Note: Examples that follow demonstrate the use of this function in a Visual Basic for Applications (VBA) module. For more information about working with VBA, select Developer Reference in the drop-down list next to Search and enter one or more terms in the search box.
This example uses the TypeName function to return information about a variable.
Dim NullVar, MyType, StrVar As String
Dim 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()".
