History of VB.NET • 2002: Version 1.0 • 2003: Version 1.1 – The first version to be included as part of the Windows operating system (Windows Server 2003) – Better performance and reliability of the .NET IDE – .NET Compact Framework • 2005: Version 2.0 – Full 64-bit support for 64-bit hardware platforms – Improved ASP.NET support • 2006: Version 3.0 – Added support for Windows Vista and Windows Server 2008 operating systems – New APIs for XML, graphics, workflow, web services, and e- business • 2007: Version 3.5 – Included in Visual Studio 2008 – Still uses CLR of version 2.0 – Language Integrated Query (LINQ) – Support AJAX web programming without page reloading – New classes in the base class library • 2008: Version 4.0 – Parallel extensions to improve parallel extensions; multi- core distributed systems • PLINQ, Task Parallel Library – Support for a subset of the .NET Framework and ASP.NET – Code Contracts – M programming languages; OSLO – Software transactional memory support Objectives: The .NET framework To provide a consistent object-oriented programming environment – To provide a smooth code execution environment – To make the developer experience consistency across widely varying types of applications – To build all communication on industry standards to ensure that code based on .NET can integrate with any other code .NET vs. JAVA  Both are object oriented .NET  mainly works on Windows, even though it’s supposed to be platform independent JAVA  x - platform support  desktop applications suck with JAVA .NET vs. C#  same runtime engine  language is very similar; functions, variables, constants, loops etc. Data Types:  Byte  Short  Integer  Long  Single  Double  Boolean  Object  Char  String  Decimal New in 3.0: 1. Windows Presentation Foundation (WPF) 2. Windows Communication Foundation (WCF) 3. Windows Workflow Foundation (WF) 4. Windows CardSpace New in 3.5: 1. Uses CLR of 2.0 2. Includes compilers for C# and VB NET 9.0 3. ASP.NET – AJAX: no page reloading Integrated Development Environment: 1. Languages supported by VS 2008: unlmtd. 2. How to compile and execute a VB.NET application 3. Major components of VS 2008 4. How to design a VB Application 5. Project and solution concepts Solution .NET FrameworkVisual Studio Project Common Language Runtime Integrated Development Environment Source files Visual Basic compiler 1 2 3 Assembly Intermediate Language (IL) Class references Common Type System  The ability of objects programmed in different languages to interact Base Class Library: (Namespaces) 1. System 2. System.Collections 3. System.IO Data Types (Byte, short, long, integer) are Objects; Objects, Date, and String are Data Types The form itself is an Object Variable names are not case sensitive! So Dim susan as String = Susan (same thing) Decimal vs. Double:  Double 1. Less precise 2. Less memory  Decimal 1. More sig figs --- more precise! 2. Takes up more memory Classes: 1. Single 2. Double When you open a project file; it opens the solution. When you open a solution file; it opens all projects within the solution. Project file can be stored with the solution file. Properties:  Name – languageTextBox  Text – what shows up in the form, or label 1.
