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The VB6 syntax is obsolete as it was introduced to simplify migration from VB6 projects.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
