Functions can return values using two different syntaxes. The modern, and correct, way to do it is to use a Return
statement. The VB6
way, i.e. old way, is to assign a return value to the function’s name .
The VB6 syntax is obsolete as it was introduced to simplify migration from VB6 projects. The compiler will create a local variable which is
implicitly returned when execution exits the function’s scope.
Return
statement should be used instead as they are easier to read and understand.
Noncompliant code example
Public Function FunctionName() As Integer
FunctionName = 42 ' Noncompliant
End Function
Public Function FunctionNameFromVariable() As Integer
Dim Value As Integer = 42
FunctionNameFromVariable = Value ' Noncompliant
End Function
Compliant solution
Public Function FunctionName() As Integer
Return 42
End Function
Public Function FunctionNameFromVariable() As Integer
Dim Value As Integer = 42
Return Value
End Function
