15
Client/Server Architecture cont

• Fat client Thin Client

16
Microsoft Visual Basic 6 as a RAD environment

• Introduction to MS Visual Basic 6
• Event-driven Programming Language
• Object Based instead structured or Object
  Oriented
• And is part of Visual Studio

17
Introduction to Visual Basic 6

• Recently released Visual Basic.net the latest of
  Visual Basic language is fully object oriented
  language with Implementation inheritance (N.B. WE
  USE ONLY MSVISUAL BASIC 6 FOR THIS COURSE)

18
Introduction to Visual Basic ..

• Visual Basic 6 does not have implementation
  Inheritance instead it has interface inheritance
  .
• Visual Basic supports OLE(object Linking and
  Embedding)
• COM(Component Object Model Architecture) and
  Later into DCOM(Distributed Component Object
  Model Architecture)
