User FAQs

1) What is an Enumeration ?
An Enumeration provides a way of grouping a collection of symbolic constants so they can be identified easily.
The underlying data type cannot be explicitly defined because all enumerations are defined with a Long data type.
An Enumeration is a value data type.

2) Can you define an Enumeration that contains three cities ?
If you do not specify any integer (Long) numbers, the first item will have a zero (0) value and subsequent items will be in sequential order.

Public Enum enMyCities1 
   London     'defaults to the value 0  
   Tokyo      'defaults to the value 1  
   Paris      'defaults to the value 2  
End Enum 

Public Enum enMyCities2 
   London = 100 
   Tokyo = 200 
   Paris = 300 
End Enum 

3) Is it possible to return the string names instead of the numbers from an Enumeration ?
No. This can only be achieved by creating a function that matches the numerical values to their corresponding string names.

Public Function GetCityNames(ByVal enValue As enMyCities) As String 
   Select Case enValue 
      Case enMyCities.London : GetCityNames = "London" 
      Case enMyCities.Tokyo :  GetCityNames = "Tokyo" 
      Case enMyCities.Paris :  GetCityNames = "Paris" 
   End Select 
End Function
