This is made possible by the rich set of classes that have been built in the .NET Framework.

VB.NET 2005 Free Training: Setting and Adding Properties to a Windows Form - In this tutorial we wil leran about Setting and Adding Properties to a Windows Form, Using the Visual Designer to set Windows Form Properties, Setting Windows Forms Properties programatically and Using Visual Inheritance along with the sample project and screen shots.

VB.NET 2005 Free Training: Using Application Class and Message Class - Visual Basic 2005 introduces a speedy way to access many important classes relating to the Computer on which the application is running, the user running it, the application itself, its forms and any associated web services. The best part of it all is that you can access it all using the new My object. The new My object has added features that help the programmer to gain access to some functionality that was really hard to achieve.

Exploring the Forms Designer generated code - As you create a new project in the Visual Basic, the IDE generally automatically adds lots of lines of code on its own. Visual Basic 2005 comes with an option to skip over this behavior of the Visual Basic IDE. The default option comes with this behavior enabled.

VB.NET 2005 Free Training: Windows Forms Designer Window - Using The System.Windows.Forms.Form class System.Windows .Forms.Form class is the foundation class for all forms to be created. All the forms that are created in VB .NET are also inheriting from this base class. This class provides for all the facilities needed for the form. Additional functionality can be added by separate codes.

VB.NET 2005 Free Training : Visual Studio.NET Namespaces - The .NET Framework class library has thousands of classes which are needed for developing and deploying solutions. In order to organize all those classes for ease of use .NET Framework uses namespaces. This Gives the Classes their own space and prevents conflicts between the various names in these classes. For instance if two classes contain a method Paint(), then to avoid conflicts in names we can place these classes in two different namespaces. Thus namespaces allow classes to be grouped in a consistent, hierarchical manner.

Implementing Class Library Object in VB.NET 2005 Class: Classical Object Oriented Concepts explain a class as a cookie cutter. A class allows you to create objects of the class. As a programmer you define a class with data fields, properties, methods and events. Then you can create objects based on that class that have state (fields, properties) and behavior (methods, events). A class can be considered as a specification of how the object of the class should look like and behave.
