In this hands-on instructor-led VB.NET OOP course, developers learn the fundamental skills that are required to design and develop object-oriented applications (OOP) for the Web and Microsoft Windows using Microsoft Visual Basic.NET and the Microsoft Visual Studio .NET development environment.
This object oriented Visual Basic .NET training course is offered in two flavors – a 3 day version for programmers experienced in another object oriented language such as C++, Java, or Delphi, and a 5 day version for less experienced programmers who are not familiar with object-oriented design and programming, and for Developers moving to Visual Basic .NET as their first fully object-oriented language. Programmers with a background in Visual Basic 6 and COBOL, for example, will want to take the slower paced more introductory 5 day course where the fundamental topics of classes, objects, and inheritance are covered in detail. The 5 day version is intended to be fully accessible to programmers who do not already have a strong background in object-oriented programming. The 3 day version covers the same topics but at a much faster pace where the more introductory topics are just reviewed and the syntax covered, and differences between Visual Basic .NET and other OOP languages are discussed.
This is a fully hands-on Visual Basic .NET training course. After each major topic is introduced students undertake short exercises to ensure they understand the important principles. This VB.NET training course cover all the object oriented topics you need to understand to develop using Visual Basic with the .NET framework – using existing classes, writing your own classes, using inheritance, utilizing and implementing interfaces, polymorphism, the standard .NET interfaces, how to work with generics, and an introduction to design patterns.
Visual Basic .NET as a language is elegant and powerful. But to utilize its capabilities fully, you need to have a good understanding of how it works with the .NET Framework. The course explores several important interactions between Visual Basic .NET and the .NET Framework; how to implement standard interfaces, how to use the built-in classes for collections, and delegates and events. It includes a succinct introduction to creating GUI programs using Windows Forms. It discusses memory management and the garbage collector, the consequences on destructors, and how to work with iDisposable.
