Study Notes

Visual Basic .NET - Intermediate Programming - Week 2

  • Visual Basic .NET is a programming language developed by Alan Cooper in the late 1980s.
  • Its primary purpose was to make GUI programming easier for developers.
  • The GUI (Graphical User Interface) aspect focuses on graphics, forms, and icons instead of text commands.
  • This language runs on the .NET framework, giving it access to extensive .NET libraries.
  • VB.NET is designed for both beginners and advanced programmers. It's highly reliable and scalable.
  • It supports object-oriented programming (OOP) concepts like encapsulation, inheritance, and polymorphism.
  • VB.NET features automatic memory management through garbage collection.
  • The VB.NET development environment (IDE) is primarily based on Microsoft Visual Studio.
  • Key IDE elements include an integrated development environment (IDE), menus, toolbars, toolboxes, the output window, and the code designer.
  • Visual Basic.NET, although an evolution of Visual Basic 6, isn't compatible with it.
  • VB.NET has gone through several versions (7.0, 7.1) with various improvements to the .NET Framework support.
  • Recent versions (e.g., VB.NET 8.0, 9.0 & 10.0) include enhancements such as anonymous types and string interpolation in response to requests from developers.
  • The IDE provides a drag-and-drop GUI design.
  • The simple syntax and drag-and-drop controls make it user-friendly and fast for development.
  • Visual Basic .NET is suitable for both small-scale and large-scale projects, including enterprise systems.
  • Despite its ease of use, some disadvantages include the inability to work directly with pointers which requires more CPU cycles, which in turn can cause processing delays.
  • The language's widespread use has created a large talent pool, but this can make securing a job as a VB.NET programmer more competitive.
