Question

I usually do something like the example below when I need to return error messages from a function, if no errors occur I just return an empyty string. Is this best practice, or are there alternatve ways of returning error messages from functions?

Function Test() as String   ' Do something   If error occured Then        Return 'Some error message'   Else        Return ''     End Functon

Instead of returning an error message you should throw an exception that contains the error message.
