Transcription de la présentation

  1. IE 423 – Design of Decision Support Systems Visual Studio Introduction to VB.NET programming

  2. Important Events Submit Term Project Proposal by Monday, April 7th

  3. Keepin Up • Read • Pol and Ahuja – Chapter 10 – Visual Studio • Pol and Ahuja – Chapters 11-13

  4. DSS Application Programming • Spreadsheets, Databases, etc. are tools to support decision making • You still need a delivery systems • Sometimes you can build a delivery system within a tool – like Access • …but it often involves some programming

  5. DSS Application Programming • We will be using Visual Basic.NET • Don’t worry about the .NET part yet • VB programming model • Object Oriented Programming • Event-driven programming

  6. DSS Application Programming • Object Oriented Programming • As oppose to ? • Focus on objects as the major organizing principle for the software • …rather than the procedure or algorithm as the organizing principle • In part, it is about how you think about the program and its design

  7. DSS Application Programming • Object Oriented Programming • Objects are things in the program • Objects have attributes, usually called Properties • Properties have a name and one or more values • Values can change or be set by your program

  8. DSS Application Programming • Object Oriented Programming • Objects have actions, called Methods • Methods are things that the object do,… • …or have done to them • Methods are components of objects • Not independent

  9. DSS Application Programming • Event-driven Programming • Events are things that can happen to objects • In VB many events are predefined (click) • …but you can define others • Code (program code – the code that you are going to write) is associated with events

  10. DSS Application Programming • So, how do you start thinking about developing a program? • What’s the “old” way?

  11. DSS Application Programming • What are the objects in your problem and your design? • Some problem specific • Some are UI objects • What are the properties of these objects? • What should happen when events happen to these objects?

  12. DSS Application Programming • Note: your programming language must support object oriented, event-driven programming • Visual Basic • Visual C++ • Visual C# • C++ (object oriented)

  13. DSS Application Programming • Visual Studio • A place to make movies? • A place to make music videos? • A type of apartment with big windows? • IDE – Interactive Development Environment

  14. DSS Application Programming • Visual Studio IDE • An environment to create and edit software • …to run and test the software • Has many, many tools to make software development easier • Controls • Windows • Web • Servers • Helps manage software development • Configuration management

  15. DSS Application Programming • Visual Studio IDE • You can run you software in Visual Studio • When it is finished and tested you can make a standalone software package

  16. DSS Application Programming • Visual Studio IDE • Mostly for MicroSoft Development products
