Custom Routines (Cross Ref > Language Details)

By Mike Prestwood

VB Classic versus C++/CLI: A side by side comparison between VB Classic and C++/CLI.

Language Details

Language Details is kind of a catch all for stuff that didn't make it into language basics nor any other category.

Custom Routines

[Other Languages]

Languages Focus

For non-OOP languages, a custom routine is a function, procedure, or subroutine and for pure OOP languages, a custom routine is a class method. Hybrid languages (both non-OOP and OOP) combine both.

VB Classic: Sub, Function

VB Classic is a non-OOP language with some OOP features. It offers both Subs and Functions. A Sub does not return a value while a Function does. When Subs and Functions are used in a class module, they become the methods of the class.

Syntax Example:

Sub DoSomething(ByVal pMessage As String)

  MsgBox (pMessage)

End Sub

Function GetAge(ByRef pFullname As String) As Integer

  GetAge = 7

End Function
